| 摘 要： | 基于Moldflow软件,采用正交试验和响应曲面法,对高铁橡胶外风挡注射成型的模拟方案优化设计,并对注射成型工艺参数进行研究。结果表明:模具温度是影响橡胶外风挡顶出时的体积收缩率和缩痕指数的最显著工艺因素,其次分别是熔体(胶料)温度、保压时间、保压压力、注射时间;优化的注射工艺参数为:模具温度185℃,熔体温度65℃,注射时间160 s,保压时间14 s,保压压力110 MPa。在此工艺参数下的橡胶外风挡顶出时的体积收缩率最大值为4.165%,缩痕指数最大值为5.103%。

| Abstract: | Based on Moldflow software,orthogonal test and response surface method were used to optimize the design of the injection molding simulation scheme of the rubber outer windshield for high-speed train,and the injection molding process parameters were studied. The results showed that mold temperature was the most significant process factor affecting the volume shrinkage and shrinkage mark index of the rubber outer windshield during ejection,followed by melt(compound) temperature,pressure holding time,holding pressure and injection time. The optimized injection process parameters were:mold temperature 185 ℃,melt temperature 65 ℃,injection time 160 s,pressure holding time 14 s,and holding pressure 110 MPa. Under this process parameter,the maximum volume shrinkage of the rubber outer windshield was 4. 165%,and the maximum shrinkage index was 5. 103%. |
