摘要
通过对某洗衣机控制面板进行工艺分析,对其注射模具进行了设计。根据洗衣机控制面板塑件的尺寸和具体结构特点,采用一模一腔模具,用热流道将熔融料输送到分型面,然后通过分流道分别以潜伏式、侧浇口形式进浇,采用油缸–隧道式结构及斜推杆机构实现侧抽动作,推杆、推管复合顶出塑件,复位杆复位。对模具采用的浇注系统、侧抽机构等设计作了简要分析。实践证明,模具结构合理、可行。
The injection mold was designed by analyzing process of the washer control panel. According to the washer control panel plastic part size and characteristics, injection mold with one mold and one cavity was used, the molten plastics was conveyed to parting surface by hot-runner system and then filled the cavity through the sub-runner with side-gate and submarine gate, the side core pulling was realized with oil cylinder-tunnel and slant ejector rod, the plastic part was ejected with ejector rod and ejector sleeve and the return rod returned. The brief analysis of the runner system and side core pulling mechanism were done. The practice prove that the structure is reasonable and feasible.
