Moldflow在鼠标注塑件成型工艺中的应用分析

Application Analysis of Moldflow in Mouse Injection Molding Process

为避免常见的熔接痕、应力痕、翘曲变形等注塑成型缺陷,基于Moldflow对鼠标外壳塑件的成型工艺参数进行CAE分析,在相同工艺参数下比较了两种不同浇注系统、冷却系统对塑件成型质量的影响,对填充时间、注射压力等工艺参数进行分析,并对翘曲变形量进行优化设计。结果证明,方案一的翘曲变形量比方案二下降了25%,牛角浇口的进胶方式对改善此类塑件的翘曲变形影响较大。

In order to avoid common injection molding defects such as fusion marks,stress marks and warpage deformation,CAE analysis of the molding process parameters of the mouse shell plastic parts is carried out based on Moldflow.Under the same process parameters,the effects of two different gating systems and cooling systems on the molding quality of the plastic parts are compared,and the filling time,injection pressure and other process parameters are analyzed.The warpage deformation is optimized.The results show that the warpage deformation of the first scheme is reduced by 25%compared with the second scheme,and the way of feeding glue into the corner gate has a great influence on improving the warpage deformation of such plastic parts.
