汽车落水槽立体旋转叠层双色注射模设计

Design of three-dimensional rotation stacked two-color injection mould for automobile rain gutter

以某汽车落水槽双色塑件为例,分析其成型工艺特点及立体旋转双色模成型的思路,设计了2副注射模,并分析了立体旋转双色注射模成型的关键技术,还阐述了模具的工作过程。模具已应用于实际生产,成型的双色塑件质量良好,达到了客户的要求,为类似双色注射模设计提供了参考。

Taking an automobile two-color plastic rain gutter as an example,the moulding process characteristics and the idea of three-dimensional rotating two-color mould were analyzed,two sets of injection mould were designed.The key technology of three-dimensional rotating two-color in⁃jection mould was analyzed,and the working process of the mould was described.The mould has been applied to the actual production,and the moulded two-color plastic parts quality was good and met the requirement of customers,which provided references for the design of similar two-col⁃or injection mould.
