Abstract

A two-dimentional finite element model of aluminum alloy die casting die for joint was established by using Pro CAST software. Equivalent plastic strain and thermal fatigue of die casting die under the heat balance condition were analyzed. Orthogonal experiment of three factors and three levels was designed with the fatigue life as the experimental goal. The results show that the order of the factors affecting the service life is presented as follows: die preheating temperature

pouring temperature and heat transfer coefficient of release agent. Die casting die has the desirable service life at the pouring temperature of 600 ℃

die preheating temperature of 250 ℃ and heat transfer coefficient of release agent of 400 W/（m
