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 application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the more demanding the products are. The higher the traditional mold design method can not meet the requirements of today. Compared with the traditional mold design, computer-aided engineering (CAE) technology is to reduce the cost and reduce the labor intensity in terms of improving productivity and ensuring product quality. In terms of aspects, they all have great advantages.
Injection molds are used in various CNC machining. The most widely used CNC milling and machining centers. CNC wire cutting and CNC EDM are also widely used in CNC machining. Wire cutting is mainly used in various applications. Straight wall mold processing, such as concave and convex molds in stamping, inserts, sliders in injection molds, electrodes for electrical discharge machining, etc. For mold parts with high hardness, machining methods can not be used, most of them use EDM, and EDM is also used for sharp corners, deep cavity parts and narrow grooves of mold cavities. The CNC lathe is mainly used for processing standard parts of mold rods, as well as mold cavities or cores of rotary bodies, such as injection molds for bottles and basins, and forgings for shafts and disc parts. In the mold processing, the application of the CNC drilling machine can also play a role in improving the machining accuracy and shortening the machining cycle.
Molds are widely used, and the forming of product components in modern manufacturing requires almost all of them. 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 CAD/CAE/CAM of the profile, and make it more intelligent, improve the forming process and mold standardization of the part, improve the precision and quality of the mold manufacturing, and reduce the amount of grinding and polishing of the surface of the part. And manufacturing cycle; research and application of high-performance, easy-to-cut special materials for various types of mold parts to improve mold performance; to adapt to market diversification and new product trial production, apply rapid prototyping technology and rapid system Mold technology, in order to quickly manufacture molding die, plastic injection mold or die-casting mold, etc., should be the development trend of mold production technology in the next 5 to 20 years.
