摘要
采用特征造型技术建立注塑件模型,利用注塑件尺寸转换公式库,实现由注塑件模型到考虑尺寸补偿的塑件模型的自动转换,进而用体扫描法建立了注塑模型芯、型腔。
The feature-based modelling technique is adopted to build plastics parts.Using formula li- brary of dimension transformation,the plastics parts considering dimension compensation are built automati- cally through modification of the feature parameters,and then the injection mold parts are established with sweep operations.
