摘　　要：研究了电气分线盒塑件的结构和材料特性,采用Moldflow软件对塑件浇口位置、填充过程、成型窗口、冷却过程等进行模流分析。结果表明:塑件在填充过程中出现质量缺陷的主要原因是塑件壁厚相差过大。在满足客户对塑件使用要求的条件下,通过优化塑件结构,以及在塑件壁厚最厚的圆柱区域进行减胶处理,使填充过程中的流动缺陷消失,气穴分布和熔接痕显著减少,提升了注塑质量,提高了开模成效。The structure and material characteristics of the plastic parts of the electrical junction box were described.The mold flow analysis for the gate location,filling,forming window and cooling were carried out by Moldflow software.The results show that the quality defects of plastic parts in the filling process is caused by the thickness difference of plastic parts.The flow defects disappear in the filling process,the cavitation distribution and weld line mark are significantly reduced by optimizing the plastic part structure and reducing the rubber in the cylindrical area where the wall thickness of the parts is largest,meeting the customer′s requirements for plastic parts,improving the injection quality and the opening effect.
