基于装配的注射模二维参数化CAD系统

Mould Based on Assembly Model

介绍了在微机上开发的基于装配的注射模二维参数化ＣＡＤ系统。即从装配几何模型开始，采用参数化方法进行模具结构设计。最后由计算机输出模具装配图、零件图、物料清单（ＢＯＭ）等信息。提出了基于装配的模具设计框架。介绍了参数化图库管理及图形实例化操作和物料清单生成等关键技术。

A 2D parametric CAD system of injection mould & die based on assembly model is introduced. The system is developed on PC systems based on top-down methodologies, and the moud design is begin first from it's assembly model. In this paper, we presented a mould design infrastructure, and introduced some key technologies, such as parametric graphic library management, manipulation methods of parametric drawings instance and BOM.
