摘要
介绍投影仪前盖注射模结构,阐述其工作过程,并从浇注系统、侧抽芯结构、推出结构、先复位结构以及冷却系统等方面分析了模具设计要点和应注意的问题,模具结构合理,动作平稳,避免了塑件的损伤和顶白,能满足塑件质量和批量生产要求。
According to the structure of the front cover of a projector and its working pro- cess, the key points and precaution of the mould design was analyzed from aspects of gat- ing system, side core-pulling mechanism, ejector mechanism, pre-return mechanism and cool- ing system.
