摘　　要：在模具加工制造和挤压模拟分析软件中大量使用三维模型,三维建模水平直接关系到加工制造出来的模具能否与设计图纸的一致,同时也关系到挤压模拟分析结果的真实性。介绍了一种新的挤压分流模具建模方法:先将模具拆分为轮廓外形、芯头、模桥三大部分,分别建立模型,再通过布尔运算将三部分整合得到所要的模型。这种建模方法能将分流模具的三维建模过程简单化,同时也可以大大地缩短建模时间,提高生产效率。Threedimension modeling has been widely used during die manufacturing and extrusion simulation software analyzing. Threedimensional modeling level plays a very im portant part in die manufacturing accuracy and coincidence with the drawing, and it has an important relation on authenticity of the extrusion simulation analyzing. A new modeling method for splitdie has been introduced. The die has been divided into three parts, as con tour, core head and die bridge in order to build up simulating model separately. Finally, through Boolean operations, the three parts to be integrated into the whole model. This di version can simplify the process of threedimensional modeling of die, can also greatly reduce modeling time and increase productivity.
