| 摘 要： | 采用Moldflow软件对轿车后保险杠三点进浇顺序注射成型的过程进行模拟.为了分析阀浇口不同的延迟开启时间对熔接痕形成的影响,进行了两组仿真实验.结果表明,阀浇口不同的延迟开启时间可以对熔接痕的形成施行动态控制,从而影响熔接痕形成的时间、压力及熔体前沿温度的变化,这样有利于降低注塑压力、消除熔接痕或把熔接痕控制在不影响其外观质量的位置,获得最佳制品质量.

| Abstract: | The plastic injection process of car hinder bumpers was analyzed based on Moldflow. The numeral simulations of the injecting with 3 points were carried out. In order to analyze the delay of different valvegate opening time effects on the formation of weld lines,two groups of simulation experiment were carried out. The results showed the delay of different valve gate opening time could dramatically control weld line formation,affect the weld line formation time,pressure and flow front temperature,reduce the ... |
