摘　　要：小模数齿轮注塑成形精度要求高,工艺要求严格,目前的工艺设计主要依赖于设计人员的经验,严重影响产品开发周期和成形质量。针对这一问题,提出了一种小模数齿轮注塑工艺智能驱动设计方法。基于定义的齿轮分区模版,通过创建截面线,利用自动识别算法完成齿轮数字化;构建细化至零件层面的知识库,在知识库中查找相似齿轮零件;依据相似零件的成熟工艺和零件层面的知识,对新零件的成形工艺进行驱动设计,实现知识重用和知识驱动。最后,在NX平台上实现了小模数齿轮注塑工艺智能设计系统,并在两家注塑产品制造企业得到应用。案例分析和工业应用证明了系统的有效性,识别检索效率提高了97%以上,试模次数减少了66%。The injection molding of small module gear requires high precision and strict process control,and the current process design mainly relies on the experience of designers,which significantly affects the development cycles and forming quality of product.Regarding this issue,an intelligent driven design method for the injection molding process of small module gear was proposed,and based on the defined gear partition templates,the gear was digitized by creating cross-sectional lines and utilizing an automatic recognition algorithm.Then,a knowledge base refined to the level of parts was constructed in which to search the similar gear parts.Furthermore,based on the mature processes of similar parts and the knowledge at the level of parts,the forming process for new parts was driven and designed to realize the knowledge reuse and knowledge driven.Finally,an intelligent design system for the injection molding process of small module gear was realized on the NX platform,which was applied in two injection molding product manufacturing enterprises.Case analysis and industrial applications show that the system is effective,with an increase of over 97%in the recognition and retrieval efficiency and a reduction of 66%in the number of die trials.
