某弧形细长零件翘曲变形的解决优化方案

Optimization Solution for Warpage Deformation of a Curved Slender Part

注塑件普遍存在翘曲变形问题,在细长条、弧状产品中表现得尤为明显。文章借助Moldflow软件,以细长、圆弧造型零件--汽车轮眉为例,从优化模具结构(调整进胶口位置)和优化产品结构(选取应力集中位置减胶)的方法有效改善由于翘曲变形带来的零件难装及外观不良问题,以满足整车外观质量要求。

Warpage deformation is a common problem in injection molded parts,especially in thin strip and arc products.With the help of Moldflow software,this paper takes the slender and circular arc molding part automobile wheel eyebrow as an example.By optimizing the mold structure(adjusting the position of the glue inlet)and the product structure(selecting the stress concentration position to reduce the glue),the problems of difficult assembly and poor appearance caused by warpage deformation can be effectively improved to meet the appearance quality requirements of the whole vehicle.
