基于Moldflow的竖梁基座气体辅助注射成型工艺优化

摘要

通过Moldflow软件对家电产品零件竖梁基座进行了气体辅助注射成型（GAIM）过程模拟仿真，并对比了不同工艺参数方案，优化得出了较好的气道布局和气体穿透效果，能够有效避免表面缩痕等产品缺陷，可以为模具设计及GAIM提供指导。%Moldflow software was used to simulate the gas-assisted injection-molding (GAIM) process for the vertical beam base as a part of household electrical appliances.The optimum airway layout and gas-penetration effect were obtained through a comparison of different process parameters.Sink marks and other product defects could be well avoided.The results obtained from this work could provide a good guide for GAIM and the relevant mould design.
