摘要
通过分析自铰链瓶盖的结构特征,设计了一模二腔三板两开式注塑模具。采用了齿轮齿条旋转脱螺纹机构和定模先推出的双推出机构,整套模具结构合理,动作可靠,制品脱模顺利,生产的塑件精度高,保证了产品质量。
Through the analysis of structural features of the hinged bottle cover,a three-plates with two parting-faces injection mould which has two cavities was designed.Both of the thread demolding mechanism with pinion and rack and stripping mechanism in the fixed mould plate were used in this mould.It is proved that the mould had reasonable structure, reliable motion ability and effective demolding property,which could satisfy the require-ments of products accuracy and quality.
