With the rapid development of information technology, digital design and simulation technology has become an important means of mold manufacturing. Through CAD, CAM, CAE and other software, mold designers can perform three-dimensional modeling, structural design and process analysis on computers, greatly improving design efficiency and accuracy. For example, in the structural design process of the mold, designers can use CAD software to quickly build a three-dimensional model of the mold, and perform assembly simulation and interference inspection on it, so as to timely discover problems in the design and optimize it. At the same time, CAE software can simulate and analyze the molding process of the mold, predict the defects that may occur in the mold during use, such as stress concentration, deformation, insufficient filling, etc., and provide a basis for the optimization design of the mold. When an electronic equipment manufacturer was developing a new mobile phone shell mold, it used digital design and simulation technology to optimize the structure and molding process of the mold many times. The mold finally produced not only had stable quality, but also increased production efficiency by more than 20%.
