Abstract:
      Based on Moldflow software，orthogonal test and response surface method were used to optimize the design of injection molding simulation scheme of 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，packing time，packing pressure and injection time.The optimized injection process parameters were：mold temperature　185 ℃，melt temperature　65 ℃，injection time　160 s，parking time　14 s，parking pressure　110 MPa，at which the maximum volume shrinkage of the rubber outer windshield was 4.165%，and the maximum shrinkage index was 5.103%.
