Injection mold is the production of a variety of industrial products of the important process equipment, with the rapid development of the plastic industry, as well as plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive Industries, the application of the product to mold more and more high, traditional mold design methods can not adapt to today's requirements.
Compared with the traditional mold design, computer-aided Engineering (CAE) technology has great superiority in improving the productivity, guaranteeing the quality of products, reducing the cost and reducing the labor intensity. Injection mold in the processing, a variety of CNC machining are useful to the most applications are CNC milling and machining center, CNC wire cutting and numerical control EDM in the mold NC machining application is also very common, wire cutting is mainly used in a variety of straight-wall mold processing, such as punching in the concave and convex mold, injection mold inserts, sliders, Electrodes for EDM machining. For the high hardness of the mold parts, the use of machining methods can not be processed, most of the use of EDM, in addition to the mold cavity of the sharp angle, deep cavity, narrow groove and so also use EDM processing. and CNC lathe is mainly used for the processing of Mold rod class standard parts, as well as the rotary body mold cavity or core, such as bottle, basin-type injection mold, shaft type, disc parts of the forging die.
In the mold machining, the application of NC drilling machine can also play a role in improving the machining precision and shortening the machining cycle. Mold is widely used in modern manufacturing industry, the product component forming process, almost all need to use the mold to complete. Therefore, the mold industry is an important part of the national high-tech industry, is an important and valuable technical resources. Optimize the structure design and the Cad/cae/cam of the die system, and make it intelligent, improve the molding process and mold standardization level, improve the mold manufacturing precision and quality, reduce the surface grinding, polishing operation and manufacturing cycle; research and application of high-performance, Easy cutting of special materials to improve the performance of the mold; in order to adapt to market diversification and new product trial, rapid prototyping technology and rapid tooling technology are used to quickly manufacture molding die, plastic injection mold or die casting mould, which should be the development trend of mould production technology in the next 5-20 years.
