【Abstract】 In view of the current problems of insufficient user-friendliness and convenience in the design tools for injection mould cooling systems, the visualized design tool for injection mould cooling system had been developed, the cooling system model based on the centerline was established, the dynamic waterway generation algorithms and modular design technology were employed to achieve two rapid initial design approaches for cooling system: dynamic waterway and template-based waterway. Based on NX Group association technology, the storage and management of the topological structure and parameter information of the cooling circuit, the rapid editing of the cooling system and the automatic modification of the association circuit had been achieved. An interference checking algorithm for cooling systems was developed by using the ray tracing method, the real-time interference check of the cooling circuit during the design and editing process had been achieved. The visual reminders for design preview and interference were realized based on the NX Curve wireframe model. A cooling system design tool was developed through secondary development based on the NX software, the dynamic visualized design of the cooling system had been achieved, basically meeting the requirements of the cooling system design.更多还原
