Abstract Through deep analysis on typical mold-base structure of general injection mold, uniform modeling method of standard mold-base was proposed, in which uniform modeling was implemented by controlling the suppression of plate in standard mold-base through redundancy control parameters and the size deformation of related components. And then analysis on technology of mold-base design based on the uniform assembly model was conducted. Through control expressions, plate features construction, top-down mold-base assembly construction, and virtual assembly mating location technology, a mold-base assembly design system was developed by adopting redundancy control parameters to realize variant design and then mold-base free variant design based on uniform assembly model was implemented.

基于统一装配模型的模架设计技术研究
对通用注塑模具的典型模架结构进行深入分析,提出标准模架的统一建模方法,即利用冗余控制参数控制标准模架中模板的抑制与显示以及相关组件的尺寸变型实现模架统一建模,并研究了基于统一装配模型的模架设计技术．通过控制表达式、模板特征构造、自顶向下的模架装配构造、虚拟的装配定位关系、基于属性的部件识别等技术,开发出利用冗余控制参数实现模架变型设计的模架装配系统,从而实现基于统一装配模型的模架自由变型设计．
