【摘要】 本文介绍了描述热塑性塑料在注塑成型过程中流动行为的数学偏微分方程、简化这组微分方程的根据以及求解这组偏微分方程的方法。然后重点说明了用MOLDFLOW软件,通过有限元的方法实现熔融聚合物流体充填模具型腔时数值模拟的基本过程。最后,通过一个日立分体式空调机外盖的塑料制品的注塑成型流动模拟的实例分析,说明计算机辅助工程分析(CAE)方法在模具制造中的具体应用。更多还原

【Abstract】 In this paper the partial derivative equition to discribe the flow behavior in the injection process of the thermoplastic plastic the priniciple to simplify the eq-uitons and the method to solve the equition is discussed. Then the basic process to use Mold flow software to realize the numral simulation of the fusion polymer filling the mould cavity is introduced. At last,through the example of the cover of the the Hitaki air conditioning machine. The Application of CAE method used in die manufacture is discussed.更多还原
