摘要
本文首先对注塑模结构ＣＡＤ的重要性及尚存在的问题进行分析。接着提出在注塑模ＣＡＤ三维系统的基础上采用“自顶向下”的设计流程，对实现该流程的关键技术进行讨论，提出了塑件骨架构型、模具符号零件、装配模型等概念。此外，本文还对参数化设计技术在注塑模具结构ＣＡＤ柔性化方面的应用进行了讨论。
? The importance of the structure CAD of plastic injection mold and existing problems are reviewed first. Based on 3D CAD system of injection mold, the “Top to Bottom” flow approach is adopted for design works. The key techniques for implementation of the design flow is discussed, and in view of concept, including contour modeling of a plastic part, symbolparts and assembly model of an injection mold are presented. Moreover, the application of parametrization design technique is discussed in the flexibility of CAD structure of injection mold.
