某型仪表透明塑料罩多抽芯注塑模具设计

Design of multi-core injection mold for the transparent plastic cover of a certain instrument

以某型仪表透明塑料罩为研究对象,首先对其结构尺寸进行了分析,并对其注塑模具的型腔布置方式进行了确定,接着对模具的浇注系统、成型零件、抽芯机构、推出机构及冷却水道进行了设计计算,然后对模具进行了整体装配,最后对注塑模具的工作原理进行了阐述。

Aiming at the transparent plastic cover of a certain instrument,this paper analyzes the structure and size of the cover,determines the arrangement of the injection mold cavity,and designs and calculates the pouring system,the molding parts,the core-pulling mechanism,the push-out mechanism,and the cooling waterway.Then the mold is assembled.Finally,the working principle of the injection mold is described.
