电器壳盖热流道注射模设计

Design of hot runner injection mould for electric apparatus casing lid

分析了电器壳盖成型工艺,介绍了模具热流道浇注系统和镶拼式成型零件、斜推式内抽机构、组合式脱模机构的特点。此模具结构缩短了塑件成型周期,节省了材料,提高了产品质量,对有精度要求塑件的大批量生产,有一定的借鉴作用。

The forming process of an electric apparatus casing lid was analyzed. The structure and components of a mould for the shaping was introduced, which includes the hot runner feeding system, split forming components, inclined internal core-pulling mechanism and combining demoulding mechanism. With the use of the new structure, the forming cycle was shortened, the material was economized and the product quality was upgraded.
