Abstract: The article focuses on analyzing the characteristics and design methods of injection mold parts, reclassifies non-standard parts, and points out that establishing and calling the corresponding standard library of various parts is an effective way to improve the efficiency of mold design. In order to reduce unnecessary repetitive work and reduce the amount of drawing, the purpose of improving the design efficiency of the injection mold base and shortening the mold design cycle is achieved. Taking NX10.0 as the platform and the NX/OPEN secondary development technology as the tool, the design system of the injection mold base is developed by the program-based modeling method. The design system can not only generate the required mold base accurately and quickly according to the selected key parameters, but also integrates the expert knowledge and experience to reduce the designer's reliance on the design experience. Moreover, the human-computer interaction interface is friendly, the system operation is convenient, and it conforms to the domestic design standards and habits.
