Die-casting mold design is a key link in manufacturing high-quality molded parts, which directly affects the dimensional accuracy, surface quality and production efficiency of molded parts. When designing a die-casting mold, multiple aspects need to be considered, from mold structure to material selection, all of which need to be carefully designed and considered to ensure the quality and production efficiency of the final molded part.
Molded part design and requirements Before designing the die-casting mold, you first need to fully understand the design requirements and characteristics of the molded parts. This includes the shape, size, wall thickness, surface quality requirements, etc. of the molded parts. Only by fully understanding the design requirements of molded parts can we carry out reasonable mold design to meet product needs.
Mold structure design Mold structural design is one of the key factors affecting the performance of die-casting molds. Reasonable mold structure design can ensure the dimensional accuracy and surface quality of molded parts. In the mold structure design, the following aspects need to be considered: Mold cavity design: The design of the mold cavity should be reasonably designed according to the shape and size of the molded parts to ensure the dimensional accuracy and surface quality of the molded parts. Cooling system design: The design of the cooling system can affect the cooling rate and temperature distribution of the molded parts. A reasonable design of the cooling system can effectively control the cooling rate of the molded parts and avoid deformation and cracks caused by thermal stress. Runner system design: The design of the runner system can affect the uniformity of metal filling and the generation of bubbles. Reasonable design of the runner system can improve the uniformity of metal filling and reduce the generation of bubbles and defects.
Material selection Material selection is one of the important factors affecting the performance of die-casting molds. Choosing the right material can improve the wear resistance, corrosion resistance and high temperature resistance of the mold, thereby extending the service life of the mold. Common mold materials include tool steel, carbide, etc. Select the appropriate material according to the requirements of the molded parts and the production environment.
Mold processing accuracy Mold processing accuracy directly affects the dimensional accuracy and surface quality of molded parts. The use of high-precision processing equipment and technology can improve the processing accuracy of the mold and ensure that the size and shape of the mold meet the design requirements. Common mold processing techniques include CNC milling, EDM, etc. Precision machining can improve the processing accuracy and surface quality of the mold.
Mold assembly and debugging Mold assembly and debugging are key links to ensure stable performance of die-casting molds. During the mold assembly and debugging process, you need to pay attention to the following aspects: Mold fitting accuracy: The fitting accuracy of mold parts directly affects the operational stability of the mold and the dimensional accuracy of the molded parts. Through precise assembly and debugging, it can be ensured that the matching accuracy of the mold meets the design requirements. Lubrication system design: Proper design of the lubrication system can reduce friction between mold parts and extend the service life of the mold. During the assembly and debugging process, it is necessary to ensure the smoothness and stability of the lubrication system. Mold debugging: Mold debugging is a key link to ensure the quality of molded parts. It is necessary to optimize the molding process by trial molding and adjusting parameters to ensure the dimensional accuracy and surface quality of molded parts.
