| Abstract: | The key structure design points and operation process of an injection mould for a cell phone shell were stated after analyzing the forming technique of the part. The service life and reliability of the mould are improved with the integration of angle ejecting at the moving half and core-pulling by angle pin and the application of two-step ejection mechanism improves the product quality. The design points of the mechanisms mentioned above were discussed in detail. |
