【摘要】 对基于随形冷却系统的车用内饰件收纳盒的成型工艺控制进行了研究。通过正交试验设计,研究了模具温度、熔体温度和保压压力对塑件缩痕指数、型腔内残余应力和翘曲变形量的影响,得到了产品的最佳注塑工艺参数,有效提高了产品质量。最后,开发的收纳盒模具经试模注塑,产品达到了厂商的装配使用要求。更多还原

【Abstract】 The molding process control of vehicle storage box with conformal cooling system was studied.The influence of mold temperature,melt temperature and holding pressure on the performance of the storage box were observed by orthogonal experimental design,which covers the shrinkage index,residual stress in cavity and warping deformation. The optimal parameters of injection process were determined,improving the quality of the product significantly. The products produced by testing mold and injection meet the requirement of manufacturers.更多还原
