| Abstract: | The cooling system of injection mold has significant effect on the quality of the plastic parts. With the characteristics of the temperature field of injection molding taken into account, a mathematic model based upon heat transfer technique and boundary element method has been built up in this paper. Special considerations about the 3-D boundary element meshing and boundary condition are presented, too. A software (CAE) used to analyze 3-D temperature field for injection molding has been developed. Reasonable results have been obtained in practical applications. |
