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, multiple factors and variability of die temperature influence were studied, a new squeeze casting die temperature control model was established. Fuzzy Control was chosen as the control system pattern. After designing the fuzzy controller, simulation model of die temperature control system was set up in the Simulink block of Matlab, and moreover, simulation was performed in it. The simulation results show that the system has good control performance compared with the traditional PID control mode.
