挂钩注塑模具设计

Injection mould design of hook

采用塑料挂钩为研究对象,根据工艺要求和塑件结构特点,设计了点浇口三板式模具。为保证塑件的成型,设计了侧抽芯机构、先复位机构和冷却水路。结果表明,整套模具结构合理,动作可靠,生产精度高。

This article takes the plastic hook for study object. The three platc type mould with pin-point gate was designed based on technological requirements and structural charac- tcristics. The side core-pulling mechanism, early return system and cooling circuit wcrc de- signed to guarantee the moulding of plastic parts. The result show that the whole set of mould has reasonable structurc, reliable motion and high precision.
