摘要
以平板手机后盖为例,基于CAE软件Moldflow对该手机后盖塑件浇口数量与位置、充填和冷却进行分析;为减小塑件的翘曲变形,采用正交试验方法进行成型工艺参数模拟;通过极差与方差法对试验数据进行分析,得到了四个工艺参数对翘曲变形的影响程度及最佳组合工艺条件。结果表明:CAE的应用可以改善塑件的翘曲变形,得到模具合理的结构设计方案,缩短模具开发周期,提高企业核心竞争力。
Based on Ph-ablet back cover as an example, the CAE software of Moldflow was used to finish the analysis of gate number and location, filling and cooling system. In order to reduce the warpage, orthogonal test method was used through the process. Through the analysis of experimental data with range and variance method, the significant of the four conditions warpage effects and the best combination of process parameters was obtained. The results indicate that the application of CAE can improve the warpage of part and obtain reasonable structure design of the mold. Finally, the development cycle shortens and core competitiveness of the enterprise improves effectively.
