摘要：

A three-dimensional model of a hot extrusion die was developed by using ANSYS software and its second development language—ANSYS parametric design language. A finite element analysis and op-timum design were carried out. The three-dimensional stress diagram shows that the stress concentration is rather severe in the bridge of the hot extrusion die, and that the stress distribution is very uneven. The opti-mum dimensions are obtained. The results show that the optimum height of the extrusion die is 89.596 mm. The optimum radii of diffluence holes are 65.048 mm and 80.065 mm. The stress concentration is reduced by 27%.
