瓶盖热流道注射模设计

Design of the Cap Hot Runner Injection Mold

通过分析带有浅腔型内螺纹塑料瓶盖的结构特征,模具设计为十八腔均衡式分布热流道浇注系统,螺纹推管旋转自动卸螺纹的推出机构,整套注射模具结构合理,动作可靠,制品脱模顺利,生产的塑料铸件精度高,完全达到客户要求,模具结构对同类形状塑料铸件具有一定的参考价值。

Through the analysis with structural characteristics shallow cavity type inner screw of plastic bottle cap,die design for the eighteen cavity balanced distribution of hot runner system, push pipe thread rotation launch mechanism of automatic screw thread unloading,Reasonable set of die structure,reliable action, products be moulding successfully,production which is high precision plastic parts meets customer requirements fully,long service life can be in bulk the production of products, the structure of molds have a reference value to similar shape plastic parts.
