以三维CAD软件MDT4.0为平台,建立起冷挤压模具CAD系统,初步实现了模具零件的特征造型和自动装配技术,节省了手工装配时间,减少了干涉的可能性。与传统设计相比,缩短了设计周期,提高了设计质量,降低了设计人员的劳动强度。%With the 3D CAD software, MDT4.0, being the design platform, thecold extrusion die & mould CAD system is presented, which has basically realized the function of feature modeling and automatical assembly of the die & mould parts. And it can reduce the time of manual assembly process and the possibility of interference. Compared with traditional design, the design cycle is shorted, the design quality is improved and the designer's labor strength is cut down.
