摘　　要：为了解决注射模冷却系统干涉检查出错率高和效率低下等问题,在UG平台上开发了注射模冷却系统干涉检查模块,在定义冷却回路语法规则的基础上,通过对包含冷却系统零件的三维模型构造面边图实现冷却系统的特征识别,进行每条初始冷却回路子图的构造,判别图中节点属性分别获取冷却回路合理出入口数目进行冷却回路连通性检测,满足连通性要求的子图作为冷却系统干涉检查所用回路子图,在多个子图间循环选择子图节点代表的特征进行距离求解,与安全距离比较进行冷却系统干涉检查,并以一模两腔模具为例,对该系统的可行性和实用性进行了验证。To solve the problem of high error-rate and low efficiency in interference check- ing of injection mould cooling system, a module developed on the UG platform for cooling system interference checking was proposed. Based on the rule definitions of cooling circuit and the graph construction of the three-dimensional model inputted, the system achieves the sub-graphs of cooling circuit and recognizes the complete cooling system. With the ob- tained cooling system, the connectivity of cooling circuit is judged, and the further distance interference checking is realized. It is concluded that the module on NX platform for inter- ference checking of injection mould cooling system is applicable.
