Abstract: 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.
Key words: fastener cover; injection mould; gating system; demoulding; cooling system
