摘要：分析了塑料拼插件外壳的结构工艺特点，运用Moldflow软件优化分析平衡浇注系统，对浇注系统进行了填充、保压分析，确定模具结构为一模四腔，并设计了浇注系统。借助于三维设计软件设计了模具的侧向抽芯机构，在侧滑块机构的设计上采用了T形槽式结构，大大简化了模具结构。生产实践证明，设计的塑料拼插件注射模具结构稳定，成型过程中气穴分布在料流前端，排气顺畅，产品质量高，成型周期短。关键词：塑料拼插件；平衡浇注系统；侧抽芯

Abstract: The structure of the plastic bricks shell was analyzed. The balanced runner system was optimized. The filling and pressure maintaining analysis of the gating system was car-ried out by Moldflow software. The four cavity structural feature was determined and the gating system was designed. The side core pulling mechanism was designed with the help of 3D design software. The mould structure was grcatly simplified by adopting the T groove structure in side sliding block mechanism. The injection mould structure of the plastic bricks shell assembly was proved to be stable under mass production. In the forming process, the cavitation was distributed in the front of the material. The exhaust was smooth, the product quality was high, and the moulding cycle was short.
