In the development of the automotive mold industry at home and abroad, China's automotive mold industry production and sales demand and transformation and upgrading forward-looking mold technology present the following nine development trends.
1、The position of mold 3D design is consolidated
The three-dimensional design of automobile molds is an important content of digital mold technology and 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 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 stamping process (CAE) is more prominent
In recent years, with the rapid development of computer software and hardware, the simulation technology (CAE) of the stamping forming process is playing 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, which optimizes the stamping process and mold structure, and improves the reliability of mold design, and reduces mold trials for automobile molds. time. Many domestic auto 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 experience design to scientific design.
