摘　　要：气体辅助注射成型是一种特殊注塑成型工艺,其模具设计尚未形成完善的体系。文章以塑料刀叉为例,基于塑料熔体的充填流动和气体保压模拟,通过熔体充填区域和气体充填区域来评价设计优劣,进行气辅成型模具浇注系统的设计,并推荐可行的工艺参数。Gas-assisted injection molding（GAIM） is a special injection molding process with less perfect design system on products and mold. Taking a plastic knife and fork as a example, this paper introduced the running gate system design in GAIM mold based on the simulation on filling flow of plastic melt and preservation of gas, the design is evaluated the design by the fill regions of melt and gas cores. Feasible process parameters were also recommended based on the simulation-design. [ Ch,5 fig. 10 ref. ]
