基于CAE的电池盖注塑模具设计及成型工艺优化

Injection Mold Design of Battery Covers and Optimization of Forming Process Based on CAE

采用计算机辅助工程(CAE)技术分析了笔记本电池盖的结构和成型工艺性,运用Moldflow软件对塑件的进浇方案、冷却水路、填充时间、熔接线、气穴位置进行了模拟仿真,并以此为参考对塑件进行模具设计;同时,为改善塑件的翘曲变形,采用正交试验方法结合CAE仿真分析,得到电池盖的最佳成型工艺参数组合。最后,通过电池盖的实际制造验证了优化方案的正确性。

Based on CAE analysis of the structure and molding technology of a plastic battery cover, the injection, cooling water, filling time, weld line, trap location of battery cover were simulated by using moldflow software, which provided a reference for mold design. In order to improve the warping deformation of battery covers, orthogonal experiment combined CAE simulation analysis was used to get the optimal molding parameters of the plastic part.
