Abstract: On account of difficulties of squeeze casting die temperature control, squeeze casting process and factors influencing squeeze casting die were analyzed. On the basis of current heating and cooling ways of squeeze casting die, the much factors and variability of die temperature influence were studied, a new squeeze casting die temperature control model was established. The temperature control was realized by the fuzzy control pattern. After designing the fuzzy controller, simulation model of die temperature control system was set up in the Simulink block of Matlab and the analysis of simulation was operated. The simulation results show that the system has good control performance, compared with the traditional PID control mode.
