大型注塑模具设计经验与技巧

Design Experience and Skills of Large Injection Mold

以某电冰箱透明储物柜注塑模具为例,简述了大型注塑模具的设计经验与技巧。模具采用液压油缸进行外侧斜向抽芯,采用分体式斜顶进行内侧斜向抽芯,采用气压和推块联合推出塑件。模具侧向抽芯机构复杂,冷却系统设计合理。实际运行表明,成型周期和塑件质量符合客户要求。

Design experience and skills of large injection mold were introduced by using the refrigerator transparent store content ark injection mould as an example. The hydraulic cylinder for lateral oblique core-pulling, the fission style inclined top for inside-oblique core pulling, the pressure gas and push block for plastic parts demolding were adopted. Its side core-pulling mechanism was complex, and cooling system design was reasonable. Production practice proved that the forming period and plastic parts quality could meet the requirements of customer.
