手机外壳注射模设计

Development of injection mould for cell phone shell

分析了手机外壳塑件的成型工艺,详细阐述了手机外壳注射模结构设计要点与工作过程,通过采用动模斜推杆与定模斜推杆相结合的抽芯机构,使得模具使用寿命和可靠性大为提高,还介绍了定模斜推杆的设计要点。

The forming process of a plastic cell phone shell was analyzed. The key points in designing the structure of an injection mould for the shaping and the working procedure were described. The points in designing the inclined ejecting mechanism in fixed-half were stated as well. The application of integrated inclined ejecting from both moving and fixed-half extends the service life of the mould and increases the reliability.
