摘　　要：针对车灯在整车中的重要作用及设计开发困难的问题,运用先进的注塑成型分析软件Moldflow,结合灯具透明面罩模具的实际设计经验对所设计的车灯面罩模具进行仿真分析。结果表明:该面罩模具排布合理,浇口类型以及热流道选择合适,分流道和注塑工艺参数设计恰当,透明面罩的熔接痕控制在合理的区域,无气穴,整件产品收缩均匀,减少了模具开发周期和试模次数;控制了注塑生产合理的生命周期,保证了稳定的优良品率。For the importance of automobile light and the difficulty of design and development problem, the automobile light lens mold was simulated and analyzed by using high level injection tooling Moldflow combining with the practical design experience. The results show that the mold injection arrangement is reasonable, the gate type and hot runner selection are appropriate. The design of runner and injection molding process parameters is appropriate, the weld line of transparent mask is controlled in the reasonable area; there are no air traps. The shrinkage of the product is even. The injection mold production reasonable life cycle is controlled to ensure the good product stability rate.
