Through finite element simulation analysis,two different die parting modes of internal high pressure die for automotive EGR shell were analyzed,and the actual die was developed by us-ing the die opening mode with better simulation results.The thinning rate of wall thickness and forming quality of the actual part were compared with the simulation analysis results,the reasons were analyzed and the improvement measures were put forward,which obtained the obvious im-provement results in the test.
