摘要
以某汽车电池外壳为研究对象,通过Moldflow软件进行网格划分及注塑成型过程的仿真模拟.选取保压压力、冷却水温、保压时间、冷却时间作为因素,每个因素选取3个水平设计正交试验.结果表明,最佳工艺参数组合为:保压压力60 MPa,冷却水温22℃,保压时间25 s,冷却时间30 s,在此条件下塑件总翘曲变形量较传统方案降低了2.491 3 mm,通过对冷却水道进行调整,有效解决了薄壁塑件易于翘曲变形的质量问题.
Abstract
The simulation for mesh division and injection molding process of an automobile battery shell was carried out by Moldflow software.Holding pressure,cooling water temperature,holding time and cooling time were selected as the four factors of the orthogonal experiment,and three levels were selected for each factor to design the orthogonal experiment.The results show that the optimal process parameters are as follows:the holding pressure is 60 MPa,the cooling water temperature is 22℃,the holding time is 25 s,and the cooling time is 30 s.The total warping deformation is reduced by 2.491 3 mm than that of traditional design under the conditions.The quality problem that thin wall parts is easily warped and deformed is solved effectively by adjusting the cooling water channel.
