【摘要】 注射成型过程中 ,塑料熔体在模具型腔内的流动、传热过程是非常复杂的物理过程。利用注塑模CAE技术可在模具制造之前 ,对模具设计方案进行分析和模拟来代替实际的试模 ,预测设计中潜在的缺陷并及时修改。本文简要介绍了注塑模内流动、传热的数值分析理论 ,并通过几个典型例子说明了如何利用CAE的分析结果解决注塑模设计及成型加工中出现的问题。更多还原

【Abstract】 Flow and heat transfer are two very complex physical processes in plastic injection molding. Using CAE technique, the mold design can be analyzed and simulated in computer to replace the actual mold trial-and-error and potential defect can be predicted and corrected before mold is made. Theories of numerical analysis are introduced and how to use the CAE results to optimize injection mold delivery and cooling system design with some typical examples is illustrated.更多还原
