汽车座椅放倒卡扣上盖注射模设计

Design of injection mould for fastener cover of automobile seat

分析了汽车座椅放倒卡扣上盖的结构特点和成型工艺,卡扣上盖注射模采用合理的型腔布局,对浇注系统、滑块结构、塑件脱模方式和冷却系统进行了详细论述,模具结构布局合理,抽芯机构简单可靠,经实际生产验证,成型的塑件满足尺寸精度和表面粗糙度的要求。

The structural features and forming process of a fastener cover to lay the automobile seat down were analyzed. The layout of injection mould cavities for the fastener cover adopted was reasonable. The gating system, slider mechanism, demoulding method and cooling system were elaborated in detail. The mould structure layout was reasonable, and the core-pulling mechanism was simple and reliable. After the actual production verification,the formed plastic parts met the requirements of dimensional accuracy and surface roughness.
