Injection molds are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and use of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the requirements for molds are becoming more and more important. The higher comes, the traditional mold design methods can no longer get used to today's requirements. Compared with the traditional mold design, computer-aided engineering (CAE) technology is no matter in terms of improving productivity, ensuring product quality, or reducing costs and reducing labor intensity. , Both have great advantages.In the processing of injection mold factories, various CNC machining is used. The most used are CNC milling and machining centers. CNC wire cutting and CNC EDM are also widely used in mold CNC machining. Wire cutting is mainly used In all kinds of straight-wall mold processing, such as concave and convex molds in stamping processing, inserts and sliders in injection molds, electrodes for EDM, etc. For mold parts with high hardness, machining methods cannot be used, and most of them use EDM. In addition, EDM is also used for sharp corners, deep cavity parts, and narrow grooves of the mold cavity. The CNC lathe is mainly used to process standard parts of mold rods, as well as mold cavities or cores of rotary bodies, such as injection molds for bottles and basins, and forging molds for shafts and disc parts. In mold processing, the use of CNC drilling machines can also improve processing accuracy and shorten the processing cycle. Molds are widely used, and the forming and processing of product components in modern manufacturing requires almost all molds. Therefore, the mold industry is an important part of my country's high-tech industry and an important and valuable technical resource. Optimize the structural design of the mold system and the CAD\/CAE\/CAM of the molded parts, and make them intelligent, improve the molding processing technology and mold standardization level, improve the precision and quality of mold production, and reduce the workload of surface grinding and polishing of the molded parts And production cycle; research and use high-performance, easy-cutting special materials selected for various types of mold parts to improve mold performance; to get used to market diversification and new product trial production, use rapid prototyping technology and rapid manufacturing Mold technology, rapid production of forming dies, plastic injection molds or die-casting molds, etc., should be the development trend of mold production technology in the next 5-20 years.
