The 3d design of mould is the important content of digital mould technology and the basis of realizing the integration of mould design, manufacture and inspection.Japan Toyota, the United States general motors and other companies have achieved the three-dimensional mold design, and achieved good application results.Some foreign practices in the 3d mold design are worthy of our reference.In addition to facilitating integrated manufacturing, 3d mold design is also convenient for interference inspection and motion interference analysis, which solves a difficult problem in 2d design.
2. Simulation of stamping forming process (CAE) is more prominent
In recent years, with the rapid development of computer software and hardware, the simulation technology of stamping forming process (CAE) plays an increasingly important role.In the United States, Japan, Germany and other developed countries, CAE technology has become a necessary link in die design and manufacturing process, is widely used to predict the forming defects, and optimization of stamping process and die structure, improve the reliability of the mold design, to reduce the test time.Many domestic automobile mould enterprises 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 mold testing and shorten the development period of stamping die.CAE technology is gradually transforming mould design from experience design to scientific design.
