What is HPDC - Magnesium Alloy Die Casting Molds Magnesium Alloy is the lightest commonly used structural metal. Its use in die cast parts has grown dramatically, often replacing plastic parts with greater strength and rigidity at no weight penalty. Mg alloy AZ91D is the most widely-used magnesium die casting alloy, offering high purity with excellent corrosion resistance, excellent strength, and excellent castability. Corrosion resistance in AZ91D is achieved by enforcing strict limits on metallic impurities. Magnesium’s high cost limits it to weight-sensitive applications in the aerospace and automotive industries. Commonly used magnesium die casting alloys metals grades: AZ91D, AZ31B, AZ40, AZ41, AM60B, AM50A, etc. The Main Physical Of Magnesium Alloys As Below: ●AZ91D belongs to the category of cast magnesium alloy, which has a low affinity with iron, less mold sticking, and has a longer mold life than aluminum alloy. Magnesium alloy is the lightest metal among practical metals, with high strength and high rigidity. It is mostly used in lightweight parts such as automobile instrument panel frame, wiper bracket, bicycle wheel hub, steering wheel frame, etc. Magnesium alloy die castings are mainly processed by die casting assisted by subsequent processing, and the appearance can be changed by surface methods such as electrophoresis. ●AZ31B magnesium alloy is a wrought magnesium alloy with good mechanical properties and is mainly used for automobile parts, machine parts, and communication equipment. ●AZ40 magnesium alloy product use: engine gear casing, oil pump and oil pipe, instrument panel, gearbox body, crankcase, engine front cover, cylinder head, air conditioner casing, etc. ●AZ41 magnesium alloy has high strength and hardness, electrical and thermal conductivity, good wear resistance, and wear resistance. After aging treatment, the hardness, strength, electrical conductivity, and thermal conductivity are significantly improved, and it is easy to weld. ● AM60B has high elongation and impact resistance. Steering wheels and seats on cars, etc. ●AM50A has high elongation and impact resistance. Steering wheels and seats on cars, etc. Magnesium alloy die casting die life depends upon the part/tool design, as well as the Tool steels used.

Dimensional tolerance and fit of structural parts of Die-casting dies 4 Die-casting dies work at high temperatures. Therefore, when selecting the matching tolerances of die-casting dies parts, not only a certain assembly accuracy is required at room temperature, but also the structural dimensions of each part are required to be stable and reliable in operation at working temperature. Especially the parts that are in direct contact with the molten metal are subjected to high pressure, high speed, and thermal alternating stress during the filling process, and the clearance with other parts is prone to change, which affects the normal progress of die casting. The change of the fit-gap is not only related to the temperature but also related to the material, shape, volume, heating degree of the working part of the parts of the dies, and the actual fit properties after processing and assembly. Therefore, the working conditions of die-casting dies parts are very complicated. Generally, the fit clearance should meet the following two requirements: ① For the fixed parts after assembly, there will be no position deviation under the impact of the molten metal. After being heated and expanded, the deformation cannot make the fit too tight, so that the dies inserts and the sleeve plate are locally overloaded seriously, causing the dies to crack. ② For parts that are active during work, after being heated, the nature of the clearance fit should be maintained to ensure normal movement, and during the filling process, the molten metal will not cause the fit clearance. Combined with the actual situation of die-casting dies manufacturing and use, the tolerance and matching accuracy of the main parts of the die-casting dies are now recommended as follows: (1) Tolerance of forming dimensions: The general tolerance level is specified as IT9, H for holes, h for shafts, and GB/T180F for length. Individual special sizes can be selected IT6~T8 level when necessary. (2) Tolerance and fit of matching parts for forming parts: ① The fixed parts of the larger parts that are in contact with the molten metal and are heated, mainly include the sleeve plate and the insert block, the insert block and the core, the sleeve plate and the sprue sleeve, the insert block and the shunt cone, etc. The integral type and accuracy are H7/h6 or H8/h7. The inlaid hole is H8, the largest one in the shaft is h7, and the rest of the spare parts in the shaft is js7, and the cumulative tolerance of the assembly is h7. ②The matching type and accuracy of the movable parts (including push rods, push tubes, formed push plates, sliders, slider grooves, etc.), the hole is H7, the axis is e7 Or d8. ③The height tolerance of inserts, inserts, and fixed cores is F8. ④The tolerance of the base size is taken as js8. (3) Tolerance and coordination of template size: the tolerance of the base size is taken as js8; the core is cylindrical or symmetrical, and the centerline size tolerance of the hole from the base to the fixed core on the template is taken as js8; the core is non-cylindrical Or when it is asymmetrical, the edge dimension tolerance from the base surface to the fixed core on the template is taken as js8; the thickness dimension tolerance of the combined sleeve plate is taken as h10; the depth dimension tolerance of the insert hole of the integral sleeve plate is taken as h10. (4) Dimension tolerance of sliding groove: ①The dimensional tolerance of the sliding block groove to the base surface is taken as f7. ②For the combined sleeve, the dimensional tolerance from the slider groove to the bottom surface of the sleeve is taken as js8. ③For the integral sleeve plate, the dimensional tolerance from the slider groove to the bottom surface of the insert hole is taken as js8. (5) Tolerance and fit of guide post and guide sleeve: For the fixed position of the guide post and guide sleeve, the hole is H7, and the axis is m6, r6, or k6; for the clearance fit of the guide post and guide sleeve, the hole is H7, and the axis is k6 or printed. ; If the hole is H8, the axis is e7. (6) The size between the guide post and guide sleeve and the base surface: the dimensional tolerance from the base surface to the center line of the guide post and guide sleeve is js7; the dimensional tolerance of the distance between the center line of the guide post and guide sleeve is js7, or cooperated processing. (7) The tolerance and fit between the push plate guide post and the push rod fixed plate and the push plate: the hole is H8, and the shaft is f8 or f9. (8) Tolerance of core table, push rod table, and corresponding dimensions: the depth of the hole table is +0.05~+0.10mm, and the height of the pillow block is -0.03~0.05mm. (9) The tolerance level of the unmarked tolerance dimensions of various parts is IT14 level, H for holes, h for shafts, and length (height) and distance dimensions are selected according to js14 accuracy. 5.Geometric tolerances and surface roughness requirements of Die-casting dies structural parts 5 Geometric tolerance is the deviation of the surface shape and position of the part. The deviation range of the geometric tolerance of the forming part of the formed part and the reference part of all other structural parts is generally required to be within the tolerance range of the size, and no additional mark is added on the drawing. The geometric tolerances of other surfaces of the parts of the Die-casting dies are selected according to the table below and marked on the drawing. The table below Selection accuracy grades of geometric tolerances of die casting dies parts: Geometric tolerances of relevant elements Selection accuracy Coaxial between the axis of the fixed part of the guide post and the axis of the guide sliding part Level 5~6 The coaxial of each forming step surface of the circular insert to the mounting surface Level 6 Concentricity between the inner diameter of the guide sleeve and the outer diameter axis Level 6~7 The axis of the fixed hole of the insert in the sleeve is coaxial with the common axis of the holes Level 7~8 on the other sleeves The perpendicularity between the axis of the guide post or the guide sleeve Level 5~6 mounting hole and the parting surface of the sleeve plate The two adjacent sides of the set of plates are the perpendicularity of the process reference plane Level 5~6 The perpendicularity of the two adjacent sides of the insert and the other side of the parting face Level 6~7 The perpendicularity between the surface of the insert hole in the sleeve and the parting surface Level 7~8 The perpendicularity of the axis of the core fixing hole on the insert to the parting surface Level 7~8 Parallelism of the two planes of the plate Level 5 The parallelism of the opposite sides of the insert and the bottom of the parting face Level 5 The axis of the insert hole in the sleeve and the end face of the parting surface are circularly run out Level 6~7 The radial runout of the axis of the circular insert to its end face Level 6~7 Parallelism of the parting surface of the insert, the sealing surface of the slider, the combined surface ≤0.05mm of the combined block, etc. The surface roughness of die-casting dies parts not only affects the surface quality of the die-casting part, but also affects the use, wear, and life of the dies. It should be selected according to the work needs of the part. The appropriate surface roughness is shown in the table below. Surface roughness of Die-casting dies: Surface position Surface roughness Ra/pm The forming surface of inserts, cores and other forming parts and the surface of the gating system 0.1~0.2 The mating surface of inserts, cores, sprue sleeves, shunt cones, and other parts ≤0.4 The mating surfaces of guide posts, guide sleeves, push rods, diagonal pins and other parts ≤0.8 Mold parting surface, joint surface between each template ≤0.8 Support surface of core, push rod, sprue bushing, shunt cone and other parts ≤1.6 Other non-working surfaces ≤6.3 contact

Steps Of Die Casting Die(HPDC Mold) Design III Die casting mold design, We often said as design of die casting dies or die casting die design.

Select the parting surface and die casting system 4. Choose the die casting equipment 5. Determine the appropriate mold structure and draw the mold assembly sketch * 6. Calculation and verification of relevant parameters * 7. Draw the die casting mold pattern * 8. Proofreading and review * 9. Organize and archive design materials At last, The steps 7-9 of die casting mold design on this page. STEPS OF DIE CASTING DIE(HPDC MOLD) DESIGN III 7. Draw the die casting mold pattern * 7 Draw according to the national drawing standards, sometimes combined with factory custom drawing methods that are not specified by the national standards 1) Draw a die-casting drawing Before drawing the mold assembly drawing, the die-casting drawing should be drawn, and it should meet the requirements of the part drawing and process data. The size guaranteed by the next process should be marked with the words "process size" on the drawing. If after die-casting, except for repairing the burrs, no other machining is performed, then the process drawing is exactly the same as the part drawing. It is best to mark the part number, name, material, material shrinkage rate, drawing ratio, etc. under the die-casting drawing. Die casting drawing and material shrinkage are usually drawn on the mold assembly drawing. 2) Draw the mold assembly structure diagram The die-casting mold assembly drawing reflects the assembly relationship between the parts, the shape and size of the main parts and the working principle of die-casting. When drawing the mold assembly drawing, try to use a 1:1 ratio, first start drawing from the cavity, and draw the main view and other views at the same time. Code all the part numbers in order, and fill in the detailed list, marking the technical requirements and instructions for use. The mold assembly drawing should include the following: the structure of the pouring system and the overflow system, the position of the parting surface and the method of parting and taking parts, the shape of the mold and the positioning of all connecting parts, the position of the guide, the overall size of the mold, auxiliary tools ( Picking and unloading tools, calibration tools, etc.), related technical instructions, etc. 3) Draw a part drawing In addition to standard parts, all mold parts that need to be self-made should be separately drawn to meet the requirements of mechanical drawing specifications to meet the requirements of delivery processing; the drawing number of the part drawing should be consistent with the part drawing number in the assembly drawing so that it is easy to check the reason The sequence of disassembling and drawing parts of the mold assembly drawing should be: first inside and then outside, first complicated and then simple, first dismantling and drawing forming parts, and then dismantling and drawing structural parts. Graphics requirements: draw according to scale, allowing zoom in or zoom out. The view selection is reasonable, the projection is correct, and the layout is appropriate. In order to make the processing personnel easy to understand and easy to assemble, the graphics should be as consistent as possible with the assembly drawing, and the graphics should be clear. The dimensioning requirements are unified, centralized, orderly, and complete. The order of dimensioning is: first mark the main part dimensions and draft angle, then mark the matching dimensions, and then mark all the dimensions. Mark the mating dimensions first on the non-main parts drawings, and then mark all the dimensions. Other content, such as part name, mold drawing number, material designation, heat treatment, and hardness requirements, surface treatment, graphic ratio, processing accuracy of free size, technical description, etc. must be filled in correctly. 8. Proofreading and review * 8 Check the view positions of all parts drawings and assembly drawings, whether the projection is correct, and whether the drawing method meets the national standards of drawing. Whether the placement of each mold part on the assembly drawing is appropriate and whether it is clearly indicated; whether the part number, name, and production quantity on the part drawing are omitted, whether it is a standard part or a non-standard part; the material, heat treatment, surface treatment, and surface of the mold part Whether the degree of finishing is marked and clearly described; the working size and matching size figures should be correct and no missing size. Check the processing performance (whether the geometric structure of all parts, drawing methods, dimensions, etc. are conducive to processing); whether the position of the parting surface and the precision of finishing meet the needs, and whether there will be flashing. After opening the mold, can it be ensured that the die-casting parts remain on the side of the mold with the ejector device, whether the demolding method is correct, whether the size, position, and quantity of the push rod (push tube) are appropriate, and whether the push plate will be stuck by the core, Will it scratch the die casting parts. Whether the location, size, and quantity of the flow line of the cooling medium are appropriate; whether the location and size of the pouring system and the overflow system are appropriate. When the die casting part has an undercut, whether the mechanism for removing the undercut is appropriate, such as whether the slider and push rod in the inclined pin core pulling mechanism interfere with each other. 9. Organize and archive design materials 9 From the beginning to the success of mold design processing and inspection, the technical data generated during this period, such as the task book, the part drawing, the technical manual, the mold assembly drawing, the mold part drawing, the base drawing, the mold design manual, and the inspection record sheet, Trial and repair records, etc., are sorted, bound, numbered and archived according to regulations.

How To Choose Steel For Die Casting Molds What feature of die casting mold steel? Die casting mold steel has the characteristics of high production efficiency, short production process, high casting finish and strength, less machining allowance, and metal material saving. It can produce a good surface and internal quality stably and efficiently. The mold material is required to have high strength, hardness, and thermal stability, especially high thermal strength, thermal fatigue, toughness and wear resistance. Die casting mold generally use hot mold steel H13, SKD61, 8407, 8418. We recommend the steels from these two companies： https://www.swiss-steel.com/ https://www.lkm.com.cn/tool_steel_advantage.php The following requirements when selecting die casting mold steel: Working conditions of the die casting mold The working conditions of die-casting molds are very harsh compared with other molds. Because of different die-casting metals, they have to withstand a high pressure of 150-500MPa. It is often in contact with molten metal at 300℃～1000℃ when working, and the pouring temperature of different die-casting alloys is also different. And the heating and cooling are repeated continuously, and the temperature gradient along the cross-section is very large. When the mold cavity with molten metal injected at a high speed of 150m/s～70m/s, severe wear will occur. Under the action of liquid metal erosion, the metal is easy to adhere to the surface of the mold cavity, and even penetrate into the mold surface to corrode the mold. ​ Other requirements of die casting mold steel Pressure casting can cast parts with complex shapes, high precision, small surface roughness, and good mechanical properties. Therefore, the die-casting mold steel should have the following requirements as below: Greater high-temperature strength and toughness Excellent high temperature wear resistance, oxidation resistance, and tempering resistance stability Good thermal fatigue performance High resistance to melt damage Good hardenability, small heat treatment distortion Good machinability and grinding properties The internal structure of the material is uniform without defects ​ Principles for the selection of die casting mold materials It can meet the requirements of the working conditions of the die-cast material. The mold size is determined according to the size of the die-cast part. Large and medium-sized precision die-casting molds should be made of steel with good processing performance, reliable performance, and long mold life. Free Quote & Part Analysis → ​H13 die casting mold steel H13 is hot die steel, which is formed by adding alloying elements on the basis of carbon steel. H13 die steel is used to manufacture forging dies with high impact load, hot extrusion dies, precision forging dies; die-casting dies for aluminum, copper, and their alloys. ​ 8407 die casting mold steel 8407 is mainly used for various metal die-casting molds, high-quality plastic injection molds. Such as engine molds, automobile lamp molds, etc. In die-casting molds, 8407 steel can be used for mold inserts, cores, cavities, gates, plungers, sleeves, etc. ASSAB 8407 The advantages of 8407: excellent thermal shock resistance and crack resistance, high-temperature strength, regardless of size, toughness, and ductility, high isotropy, excellent workability, and polishability, excellent hardenability, good heat treatment size Stability, and improvement of mold life. SKD61 die casting mold steel SKD61 has good toughness and high-temperature fatigue resistance, can withstand temperature fusion, is suitable for long-term work at high temperatures, and has good cutting performance and polishing performance. It is suitable for making aluminum, zinc, copper alloy die-casting molds, etc.; it is an ideal material for making ejector pins and barrels. 8418 die casting mold steel 8418 has excellent resistance to thermal fatigue cracking, thermal shock cracking, thermal wear, and plastic deformation. These unique properties make it the best choice for die-casting die steel. Used for zinc, magnesium, aluminum, titanium alloys die casting mold, etc. ASSAB 8418 has the following characteristics: 1. Excellent toughness, ductility, and homogeneity 2. Excellent anti-tempering softening performance 3. Excellent high-temperature strength 4. Excellent hardenability 5. Excellent heat treatment dimensional stability and plating performance How to improve mold life of die casting mold steel: 1.After heat treatment, the die-casting mold steel can ensure its required strength, hardness, stability, thermal fatigue resistance, and material cutting performance. 2.Strengthening the surface of die-casting die steel is currently the most effective way to extend the mold life of die-casting die steel. There are three main types of surface strengthening: It is not changing the surface chemical composition, laser phase change hardening, etc. It is changing the surface chemical composition, nitriding, etc. It is forming a covering layer on the surface, processing by vapor deposition technology, etc. By adjusting the general heat treatment process, the strength and toughness of steel can be effectively improved, and the mold surface can be given high hardness, wear, and corrosion resistance, seizure resistance, low friction coefficient, and many other excellent properties, so that the service life of die casting mold steel can be increased several times or even dozens of times. contact

Digest the process data, analyze whether the die casting method, equipment model, material specification, mold structure type, and other requirements proposed in the process task book are appropriate, whether the die casting equipment of the die casting production unit, the processing capacity and equipment conditions of the die processing unit can be implemented. Die-casting materials should meet the strength requirements of die-casting parts and have good fluidity, uniformity, isotropy, and shrinkage. According to the purpose of die-casting parts, die-casting materials should meet the requirements of electroplating metal conditions, decorative properties, necessary mechanical properties, or weldability. 2) Structural analysis of die castings Digest the drawings of die-casting parts, understand the purpose of the parts, and analyze the technical requirements of die-casting parts such as manufacturability and dimensional accuracy. For example, what are the requirements for die-casting parts in terms of appearance and performance, whether the geometric structure of die-casting parts, slope inserts, etc. are reasonable, the allowable degree of die-casting defects such as flow marks, shrinkage holes, and porosity, whether there is a coating, Electroplating, machining, etc? Select the dimension with the highest dimensional accuracy of die-casting parts for analysis, and see if the estimated die-casting tolerance is lower than that of die-casting parts, and whether die-casting parts can be die-casted. Specifically including (1) Under the condition of satisfying the structural strength of die castings, a thin-walled structure should be adopted. This not only reduces the weight of die casting but also reduces the thermal load of the mold. The wall thickness of die castings should be uniform, avoid hot spots, reduce local heat concentration, and reduce thermal fatigue of mold materials. (2) All corners of die-casting parts should have appropriate casting fillets to avoid the formation of edges and corners in the corresponding parts of the mold, resulting in cracks and corners. (3) Narrow and deep cavities should be avoided as far as possible on die castings, so as not to cause sharp splits in the corresponding parts of the mold, which will deteriorate the heat sink and cause fractures. When the die castings have smaller size round holes, they can only be on the surface of the casting. Press the punching hole position of the sample, and then post-process the die-casting part. 3. Select the parting surface and die casting system 3 According to the basic principles of selecting the parting surface, the position of the parting surface is reasonably selected, and the number and distribution of the cavity are determined according to the structural characteristics of the die-casting part, and the form of the gating system is selected reasonably so that the die-casting part has the best die-casting forming conditions and the longest The mold life and the best mold machining performance.

Custom Die Casting In China Customized Die Casting Die Casting using a mold or a reusable competitive cost mass production manufacturing process is complicated metal parts. This process is highly automated devices; it involves four key elements: metal raw material, the furnace, the mold, and die casting machines. Metal die casting processes are generally used in aluminum, magnesium, brass, copper, zinc, or several metal alloys. However, the composition of the alloy used may vary, depending on the specifications and product requirements of individual customers. In the production process, The metal melts in a hot chamber or a cold chamber. Cold chamber furnaces refractory metal such as aluminum, and the hot chamber furnaces low-melting metal such as zinc or a metal alloy. Once the metal in a liquid state, the die casting machines will be forced into a mold, and then rapidly cooled and solidified into the desired shape. The die casting process is almost automated, so labor costs are low. However, the high-costed complexity of using the steel die and the die casting tools require mass production in order to a relatively low cost per unit. Free Quote & Part Analysis → Die Casting Metals And Alloys The die casting process usually uses aluminum alloys, magnesium alloys, and zinc alloys. The choice of a particular alloy depends on the physical properties and design features required for the final casting. Quality such as density, corrosion resistance, melting point, and strength may be decisive factors along with cost factors. Aluminum Magnesium Zamak alloy Cooper Each metal used has specific properties, in certain cases, it may prove advantageous. For example, aluminum alloys generally have the advantages of lightweight and corrosion resistance. In contrast, the copper alloy generally higher cost but has excellent electrical conductivity. The required part design features may also greatly influence the choice of materials used for die-casting parts. Certain metal alloys (e.g. Zn) exhibit a high degree of ductility for parts having better surface finish and a thin, these alloys could be a good choice. Zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (Zinc ), Aluminum , Magnesium and Kupfer (Copper ). The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. These alloys are most commonly die casting. -Copyright Wikipedia The choice of material also affects the processing possibilities. Aluminum alloys with much higher melting points require cold-chamber die casting machines, While zinc and other alloys melt at low temperatures using hot-chamber die casting machines. contact

How Does Hot-chamber Die Casting Machine Work Hot-chamber die casting machine is a kind of die-casting machine with a high degree of automation, less material loss, and higher production efficiency than the cold-chamber die-casting machine. It is suitable for die-casting zinc, lead, and other low-melting non-ferrous alloy parts and can be widely used in automobiles and motorcycles: accessories, instruments, household hardware, household appliances, and other industrial sectors. Working principle of hot chamber die casting machine: When the shot hammerhead rises, the molten metal in the crucible enters the pot press chamber through the pot inlet. After the mold is closed, the molten metal fills the die casting cavity from the nozzle head along the channel after the hammerhead is pressed down. Medium solidification molding, the injection hammerhead rises, the mold is opened to take out the casting, and a die-casting cycle is completed. The injection chamber of the hot chamber die-casting machine and the injection punch are immersed in the molten metal. The injection chamber is connected with the gate of the die-casting mold through a gooseneck tube. The structure of the hot chamber die casting machine: The hot-chamber die casting machine is mainly composed of four parts: mold clamping device (also called mold clamping device), injection device, hydraulic transmission system, and electrical control system. The mold clamping device mainly plays the role of closing and opening the mold, locking the mold, and ejecting the product. It is mainly composed of a fixed seat plate, a movable seat plate, a tie rod, a mold clamping hydraulic cylinder, an ejection mechanism, a mold adjustment device, and a safety door. The hydraulic transmission system is a system that transmits power through various hydraulic components and circuits to realize various action programs. It is mainly composed of hydraulic pumps, lock/open mold hydraulic cylinders, thimble hydraulic cylinders, buckle nozzle hydraulic cylinders, and injection hydraulic cylinders. , Various control valves, accumulators, oil tanks, coolers, hydraulic oil, etc. The electrical control system is to ensures that the machine works according to the predetermined pressure, speed, temperature, and time. It is mainly composed of a motor and various electrical components, meters, and electrical circuits. Features of hot chamber die casting machine: Die-casting of low-melting-point alloys is usually the main method, and zinc alloy is the most typical one; It is suitable for the production of small die-casting parts, while hot-chamber die-casting is not suitable for medium and large-scale die castings; The molten metal filled into the mold cavity always flows in the closed channel, and the oxidized inclusions are not easily involved, which is more beneficial to the quality of the die casting; The automation of die-casting process is easy to realize; Since no pouring procedure is required, the production efficiency is higher under normal operation; The injection pressure is slightly lower, and there is no pressurization stage in the injection process, but it has little effect on small and thin-walled parts; The life of hot work parts such as injection punches, pouring pots, nozzles, etc. is difficult to grasp and control, and it takes time to replace after failure; When replacing or repairing the furnace, it is necessary to disassemble and assemble hot work parts, which increases the auxiliary time; For the hot chamber die casting of high melting point alloys, magnesium alloy is still more suitable at present, and the hot chamber die casting machine used for magnesium alloys also has the above-mentioned characteristics.
