| 摘 要： | 基于Moldflow软件，针对具有复杂曲面的免喷涂高光注塑格栅可能出现缺料、困气和泛白等的外观缺陷，通过局部优化渐变壁厚、优化布置顺序阀热流道系统、改变局部熔体流动方向的设计方法，进而消除产品外观缺陷。经过实际生产验证，制备的高光格栅产品外观品质较优，可实现量产，且大幅降低了产品的报废率，节约了制造成本。

| Abstract: | Aiming at the possible lack of material， air trapping and bleached appearance defects such as gradient in the free spray specular injection?molded grid with a complex curved surface， an optimization was conducted for the design methods based on the Moldflow software. These methods included the optimization of the local wall thickness and the placement sequence valve hot runner system as well as the change of the local melt flow direction. As a result， the production of appearance defects was eliminated， and the optimal surface quality of the product appearance was achieved. This greatly reduced the scrap rate of products and saved the manufacturing costs. |
