基于CAE的解决空调器大面罩塑件翘曲变形的设计优化

CAE-based Ameliorative Design for Solving Warpage on Big Plastic Veil of Air-Condition

以大型复杂的立式空调器出风大面罩塑件注塑模设计为例,分析了注塑成型的塑料制品发生翘曲变形的原因及相应的解决措施,并重点介绍了CAE软件Moldflow中翘曲变形分析模块的原理,通过Moldflow对产品进行注塑仿真模拟,分析浇口的位置和数量的变化等对制品翘曲的影响,从而得到最佳的浇口位置、数量、形状,有效解决该大型复杂塑件注塑模设计过程中容易出现的翘曲变形等问题,对大型复杂注塑模具设计和改善产品质量具有重要的指导意义。

With design of big and complicated plastic veil’s injection mould of stand-up Air-condition as an example,this article analyzed the causation and resolving of warpage on plastic made by mould injection.The theory of warping analysis in Moldflow of CAE was emphatically introduced.By injection simulation on plastic using Moldflow and analyzing the effect of gate′s location and number on warpage,getting the best location,number and form of gate accordingly.The problem of warpage on big and complicated plastic was effectively solved.It had important guiding significance not only on design of big and complicated injection mould,but also improving the quality of production.
