摘要：

In the present study, simulations of the injection mold-cooling process are developed by using a modified boundary element technique. The mold cavity surface temperature distributino is first calculated on a cycle-averaged basis. The temperature distribution and the temperature profile of the polymer melt and the corresponding transient heat flux on plastics-mold interface are then computed by finite difference method in a decoupled manner. Finally, the difference between cycle-averaged heat flux and transient heat flux is analyzed to obtain the cyclic transient mold cavity surface temperature. The analysis results for a box mold are illustrated and discussed.
