摘　　要：通过对座体零件进行结构分析,利用Pro/E软件完成了零件和毛坯的三维建模,采用自顶向下的方法设计了熔模精铸模具。在UG中进行了模具复杂型面的数控自动编程,并在加工中心上进行加工,最后将模具的各个零部件按照设计要求进行装配,并浇注蜡液,实现了蜡型制造。According to the structural analysis of frame, Pro/E was used to finish 3D modeling of the part and roughcast,the method of top-down was used to design the invest casting mold. The mold＇s complex surface CNC automatic programming was realized in UG, which was machined on machining center. The mold＇s assembling was complemented according to the design requirements, and liquid wax was poured to achieve a wax-based manufacturing.
