| 摘 要： | 为预测注射模具在给定的冷却管道分布下型腔表面的温度分布情况，使用边界元法进行注射模的温度分析．对于注射模温度场问题，边界单元法具有数据准备量小、计算量小、精度高等优点．但由于注射模内部型腔为一狭缝，冷却孔长度远大于其直径，普通的边界单元法无法进行计算．根据注射模的结构特点，推导出适用于注射模冷却分析的边界积分方程，并给出模具三维温度场的边界元计算方法．实践表明，该软件对注射模冷却系统的分析和设计具有较好的指导作用．

| Abstract: | This paper presents a method for analyzing the heat - transfer process during the cooling stage of injection molding of plastics. The mold is treated as cyclic - steady - three - dimenstional conduction. To solve the relevant governing equations simultaneously, the present formulation uses a hybrid scheme consisting of a modified - three - dimensional - boundary - element method for the mold region and a finite - difference method with a variable mesh for the melt region.These two analyses are iteratively coupled so as to match the temperature and heat flux at the mold - melt interface. |
