| 摘 要： | 选取汽车前门窗框为研究对象,基于CAE原理,运用Moldex3D模流软件分析后发现,导致翘曲变形量较大的原因为塑胶流动不平衡。根据流动平衡原理进行浇口位置的变更设计,再次模流分析显示最大翘曲位移量从18.54 mm降至14.05 mm,降低了24.22%;最大成型压力从224 MPa降至171 MPa(单一模穴),降低了23.66%;最大锁模力从2 003 t降至1 474 t(单一模穴),降低了26.41%。

| Abstract: | The front door and window frame of the car were selected as the research object. Based on the CAE principle, the Moldex3D mold flow software was used to analyze and found that the cause of the large warpage deformation was the plastic flow imbalance. According to the flow balance principle, the gate position is changed. The mold flow analysis shows that the maximum warpage displacement is reduced from 18. 54 mm to 14. 05 mm, which is reduced by 24. 22%. The maximum forming pressure is reduced from 224 MPa to 171 MPa(single cavity), which is reduced by 23. 66%. The maximum clamping force decreased from 2 003 t to 1 474 t(single cavity), which is reduced by 26. 41%. |
