摘要
对按钮塑件的结构进行了分析,根据塑件特点:一是塑件侧面有一个通孔,需要设计侧抽芯机构;二是塑件底面有一个圆形铜嵌件,需要在模具上进行固定。选用一模四腔,然后初选注射机,再设计分型面、浇注系统、脱模机构、成型零部件、其它零件以及选择模架。
The structure of the button plastic part is analyzed according to the characteristics of the plastic part:first,there is a through hole on the side of the plastic part,which needs to design the side core-pulling mechanism;second,the bottom surface of the plastic part has a circular copper insert,which needs to be fixed on the mold.One mold and four cavities are selected,then the injection machine is selected,and the parting surface,gating system,demoulding mechanism,forming parts,other parts and mold base are designed.
