摘要：通过对卡通玩具壳盖的结构的分析，设计出能够安装在角式注塑机上的一模八腔、角式结构注塑模具。为了减少多模腔产品的各腔差异，运用CAE软件流道平衡分析，使所有流动路径内的压力降均相同，所有型腔同时填充，型腔保压均匀，获得了一致的体积收缩率，提高了塑件的质量。模具结构设计合理，开、合模动作稳定可靠，
制品能够顺利脱模，塑件精度较高，产品质量能够完全达到客户要求。关键词：玩具壳盖：CAE：流道平衡：角式结构：注塑模

CAE analysis of flow balance and design of injection mould for a cartoon toy shell
QIAONi
Abstract: By analyzing the structure feature of a cartoon toy shell, eight-cavity mould and L-type mould that can be installed in the L-type injcction moulding machine are designed. In order that disparity of different cavities in multi-cavity products are reduced, CAE software is used to analyze the flow balance and improve the quality of plastic parts. As a result, it can be obtained that the pressure drop in different flow paths are the same, all cavities are filled simultaneously, and the cavity pressure is uniform, resulting in similar volume shrin-kage. Reasonable design of mould structure, reliable and stable opening-closing of the mould and the easy demoulding of products are fullfilled to product highly precise plastic parts which can meet customers'requirements

塑工艺来生产的。但是不同厂家生产的塑料基材质量参差不齐，部分模具结构设计滞后，产品老化严重，这都影响了产品的进一步开发与创新。本文首先利用软件进行CAE分析，得出优化参数，然后设计模具结构并试模生产。
