are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application 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 meet the requirements of today. Compared with the traditional mold design, computer-aided engineering (CAE) technology is either in terms of improving productivity, ensuring product quality, or reducing costs and reducing labor intensity. In all aspects, they have great advantages.
In the processing of injection molds, various CNC machining is used. The most widely used are CNC milling and machining centers. CNC wire cutting and CNC EDM are also very common in the CNC machining of molds. Wire cutting is mainly used in various Kind of straight-wall mold processing, such as concave and convex molds in stamping, inserts, 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 of the mold cavity, deep cavity parts, and narrow grooves. 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 application of CNC drilling machines can also play a role in improving processing accuracy and shortening the processing cycle.
Molds are widely used, and the forming and processing of product components in modern manufacturing industry almost all require the use of molds. Therefore, the mold industry is an important part of the national 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 process and mold standardization level, improve the precision and quality of mold manufacturing, and reduce the amount of surface grinding and polishing operations on the molded parts And manufacturing cycle; research and application of high-performance, easy-cutting special materials used for various types of mold parts to improve mold performance
