摘　　要：透明冰箱储物盒在注塑过程中 ,由于排气不良 ,导致制件内部产生气泡。运用注塑过程CAE软件C -MOLD对充模过程进行数值模拟 ,得到了气泡产生的原因 ;根据其生成原因 ,提出成型模具的合理设计方案 。In plastic injection moulding process of transparent boxes for article storage in refrigeratory,inner gas-hole would be produced in plastic part because of unsmooth air-exhausting.Software C-MOLD is applied to simulate and analyze the flowing processes of the melted plastics.The exact reasons and way of forming inner gas-hole is obtained.Reasonable principles are put up to modify and design injection mould,the problem of unsmooth air-exhaust is solved,and the inner gas-hole is effectively eliminated.
