速印机上合盖倒装式热流道注射模设计

Design of Flip Chip Type Hot Runner Injection Mold for the Printing Speed on the Cover

以一塑料上合盖为例,介绍了油缸推动推板带动侧抽芯开模的模具结构,由于塑件工艺要求,采用特殊运动脱模机构,利用倒装斜顶侧抽芯模机构和热流道点进胶的创新结构。经生产实践,该模具结构设计合理,动作可靠,生产的塑件质量稳定,符合塑件的技术要求。对有表面要求较高、体积较大的类似塑件注射模设计有一定的参考价值。

A plastic cover as an example, introduces the cylinder push board to drive side core-pulling molding mold structure, due to the product technical requirements, the use of special sports demoulding mechanism, using inversion inclined top side core-pulling molding mechanism and innovation structure of hot runner points gate. The production practice, the structure design is reasonable, reliable, stable production of parts quality, conform to the requirements of the plastic parts. Higher requirements on surface, large volume of similar products have a certain reference value.
