摘要
以薄板形零件为例,运用Moldflow软件找出最佳浇口位置,设计了2种浇注系统的试验方案。通过对比塑件不同浇注系统的填充分析、流动前沿温度分布分析、缩痕指数和翘曲变形量的模拟分析,综合分析了各个因素对注塑成型的影响,并确定了最佳浇注系统,为整个模具设计提供依据。模拟分析方法提高了试模效率,提高产品的生产效率和质量。采用Moldflow软件对薄壁零件注塑成型进行模拟,找出最佳浇口位置,并且建立不同浇注系统。分析不同浇注系统对塑件流动情况的影响,为整个模具设计提供依据。
The best gate location of the thin plate part was chosen by using Moldflow software. Two types of gating systems were designed. By comparing with the analysis of filling, temperature at flow front, sink marks and warpage of two different gating systems, the better gating system is determined, which provides the basis for the entire mold design. Simulation method improves not only the effwiency of testing mold, but also quality of product.
