The injection mold is an important equipment for the production of various industrial products, with the rapid development of plastic industry, plastic products and application in aviation, aerospace, electronics, machinery, shipbuilding and automobile industry, the requirements of the mold products is also more and more high, the traditional mold design method has been unable to adapt to the requirements. With the traditional mold design, computer aided engineering technology both in improving productivity and ensuring the quality of products, or to reduce costs, reduce labor intensity, has great superiority.
Injection mold in the processing of various CNC machining, all useful, is the most widely used CNC milling machine and machining center, CNC wire cutting and CNC EDM in mold machining application is also very common, line cutting is mainly used in the mold processing all kinds of straight wall, such as die stamping, insert the block and slider in injection mold, EDM electrode used etc.. For die parts with high hardness, machining methods cannot be processed, mostly EDM, and EDM is also used for sharp corners, deep cavity parts and narrow grooves of mold cavity. The CNC lathe is mainly used for processing mould rod and standard parts, rotary die cavity or core, such as injection mould, bottle pot, shaft, disk type parts die. In the mold processing, the application of CNC drilling machine can also improve the machining precision and shorten the processing cycle.
The mold is widely used, and the forming process of the product components in modern manufacturing industry is almost all needed to be done with the mold. Therefore, the mould industry is an important part of the national high and new technology industry, and it is an important and valuable technical resource. Optimization of mold structure design and the type of CAD/CAE/CAM, and make it become intelligent, improve the type forming process and die level of standardization, improve the mould manufacturing precision and quality, reduce the surface grinding and polishing operation and parts manufacturing cycle; special material research, application of needle used in various types of mold parts high performance, easy cutting, in order to improve the mould performance; in order to adapt to the market diversification and new product development, application of rapid prototyping technology and rapid tooling technology, with rapid manufacturing dies, plastic injection mold or mold, mold production technology should be the development trend in the future 5~20 years.
