Abstract：In view of the irregular shape of extrusion pipe and the phenomenon of coking and yellowing in the die of an enterprise, a new structure of two-stage buffer groove was adopted. The key parameters of the structure, that is the transition gap between the inclined buffer groove and the ring buffer groove, as well as the inclination angle of the inclined buffer groove were analyzed by simulation tests to determine the most suitable value. At the same time, in order to reduce the development cost and accelerate the development process, the secondary development of ANSYS through the combination of APDL and C++ to realize the parametric design of die structure was carried on to reduce the procedure of trial and error and improve first pass rate of the initial model and design efficiency. Finally, the verification was carried out in the factory. It can be seen from the experimental results that the new extruder head with two-stage buffer groove structure eliminates the irregular defects of extrusion products. The fracture ratio of the tube was also obviously decreased after the impact test of the drop hammer.
