摘要
汽车行李箱尾门槛板内饰件因其注塑量大,流道流程长,因而采用热流道模成型较为适宜。模具设计中,浇口位置和冷却方式的选择对产品的成型质量起到关键作用。利用MoldFlow软件对浇注系统、冷却系统及成形工艺的设定进行了两种方案的有限元模拟分析。通过CAE模流分析,对塑件在模具中的浇口位置和冷却方案进行了优化,改善了模具成型中如翘曲变形、熔接痕等潜在的缺陷,获得了合理的热流道注射模设计结构,提高了塑件成型质量,有效地缩短了汽车行李箱尾门槛板内饰件注塑模具的研制周期。
Because of the injection volume,long flow of the flow channel for the trunk of the car tail threshold plate interior parts,the hot runner molding was chosen.In mold design,the gate location and cooling methods played a key role for forming quality of the products.MoldFlow software was used to the gating system,cooling system and the forming process,two plans for the finite element simulation analysis was established.Through CAE mold flow analysis,the gate location and cooling program for plastic parts in the mold were optimized to improve the potential pitfalls of molding such as warpage,weld lines.Reasonable hot runner injection mold design was got and the plastic molding quality was improved,the development cycle of the injection molding parts for automotive trunk tail rocker panels was effectively shorten.
