塑料机器人一模多异腔注射模设计

以塑料机器人产品为载体，介绍异型组合产品的结构工艺性，确定该产品采用一模多异腔的成型方案。基于计算机辅助工程（CAE）数值模拟技术优化模具浇注系统的设计，解决流道填充不平衡的问题；同时在流道上增设特殊结构，解决注塑生产后产品的空间存放问题。根据产品的功能要求，在模具结构中设置抽芯机构，以解决产品成型后产生夹线的工艺问题。该模具在实际的生产过程中取得较好效果，为类似模具的设计提供相关的参考与借鉴。

Design of Multi-cavity Injection Mold for Plastic Robot

In this paper, the structural manufacturability of special-shaped composite products was introduced by using the plastic robot products as carriers, and the forming scheme of one mold with many different cavities was determined. Based on the CAE numerical simulation technology, the design of the mold gating system was optimized to resolve the unbalanced filling problem occurring in the flow passage. Meanwhile, a special structure was additionally arranged on the runner to solve the problem of space storage for the products after injection molding production. According to the functional requirements of the products, a core pulling mechanism was arranged in the mold to solve the technical problem of thread clamping after the product was formed. The mold achieved good results in the actual production process. This work provided a good reference for the design of similar molds.
