Research on Integrated Technique of Digital Design and Machining Simulation for Plastics Injection Mould

阐述一种注塑模数字化设计及加工过程仿真一体化技术。运用Pro/Engineer软件的通用功能模块及其模架设计专家(EMX)模块,进行塑件及其注塑模设计,并将模具中的成形零部件模型数据转换到MasterCAM中进行数控编程和加工仿真。以相机面壳注塑模设计与加工仿真为例,验证了该方法的可行性。该方法可以提高塑料注射模具的开发效率。

An integrated technique of plastics injection mould design and process simulation was elaborated. Plastics products and plastics injection mould were designed using the general function module of Pro/Engineer and its expert moldbase extension （EMX） module. Then the model data were converted and imported into MasterCAM to program NC codes and to make machining simulation. As an application example, a camera＇s shell and its plastics injection mould were designed and simulated using the proposed method. The development efficiency of plastics injection mould can be improved using the method.
