In the development of the car parts mold industry at home and abroad, the production and sales demand of China's car parts mould industry and the forward-looking mold technology for transformation and upgrading have shown the following two major development trends.

　　1. The position of mold 3D design is consolidated

　　Car parts The three-dimensional design of mold is an important content of digital mold technology, and it is the basis for the integration of mold design, manufacturing, and inspection. Companies such as Toyota and General Motors of the United States have realized the three-dimensional design of molds and achieved good application results. Some methods adopted in the 3D mold design abroad are worthy of our reference. In addition to being conducive to the realization of integrated manufacturing, the three-dimensional design of the mold has another advantage in that it is convenient for interference inspection and can perform motion interference analysis, which solves a problem in the two-dimensional design.

　　2. The simulation of the stamping forming process (CAE) is more prominent

　　In recent years, with the rapid development of computer software and hardware, the simulation technology of the stamping forming process (CAE) has played an increasingly important role. In developed countries such as the United States, Japan, and Germany, CAE technology has become a necessary part of the mold design and manufacturing process. It is widely used to predict forming defects, optimize the stamping process and mold structure, improve the reliability of mold design, and reduce car parts. Modular time. Many domestic car parts mold companies have also made significant progress in the application of CAE and achieved good results. The application of CAE technology can greatly save the cost of trial molds and shorten the development cycle of stamping molds, which has become an important means to ensure mold quality. CAE technology is gradually transforming mold design from empirical design to scientific design.
