With the continuous development of science and technology, digital mold technology has formed a mainstream direction. In recent years, the digital mould technology has been developed rapidly and rapidly. It is one of the effective ways to solve many problems in the development of automobile die. The so-called digital mold processing technology, in fact, is the application of computer technology or computer aided technology (CAX) in the manufacturing process of mold design. The successful experience of the application of computer aided technology in automobile die and mould enterprises at home and abroad is summarized. The digital auto mold technology mainly includes the following aspects:

DFM is to consider and analyze its manufacturability in the design process, so as to ensure the success of the process.

Second, the auxiliary technology of mold surface design, we strive to develop intelligent surface design to meet the technical requirements.

CAE assisted analysis and Simulation of stamping and then forming process, and actively forecast and solve possible defects and forming problems.

(4) replace the traditional two-dimensional design with the new three dimensional die structure design.

Most of the manufacturing processes of moulds are CAPP, CAM and CAT technology.

Under the guidance of digital technology, we should deal with or solve problems in the process of trial manufacture and stamping production.
