The 3D Motion Simulation of Injection Mould Based on UG II

The structure and motion characteristics of typical injection moulds are described.The motion theory and its process are introduced.As an example of the mould of a part ofdigital camera,the 3D motion simulation of mould-opening,ejection and mould-closing isestablished based on UGⅡ.By predicting problems of injection mould design,the rationalityof its structure is ensured.
