| Abstract: | A mathematical model for solving the temperature field of an injection molding die during cooling of injection molding process by means of the boundary element method is proposed with the heat transfer by coevection between melted plastics and die taken into consideration. The formulae for calculating the coefficients of heat transfer by convection have been derived. With the computer programs written, the temperature fields in the die under steady and unsteady conditions have been calculated. The correctness of the mathematical model and numerical results are confirmed by experimental results. |
