The invention discloses an automobile headlamp shell produced based on an injection mold. The automobile headlamp shell comprises a shell body, a liquid storage groove is formed in the side wall of the shell body, a liquid pumping groove is further formed in the side wall of the shell body, a one-way liquid outlet pipe is communicated between the liquid storage groove and the liquid pumping groove, and the one-way liquid outlet pipe is annularly distributed in the shell body; the side wall of the shell is provided with a one-way liquid inlet hole communicated with the liquid storage tank and the liquid pumping tank, a piston is connected into the liquid pumping tank in a sealed and sliding mode, the piston is elastically connected to the inner top of the liquid pumping tank through a spring, the side wall of the shell is provided with a rotation groove, and a driving device for driving the piston to move up and down is installed in the rotation groove. According to the invention, the one-way liquid outlet pipe, the liquid storage tank, the liquid pumping tank and the piston are arranged, cooling liquid is added into the liquid storage tank, the piston is driven by the driving device to move up and down, the cooling liquid can be promoted to flow in the circulation pipeline, and therefore heat in the lamp shell is rapidly dissipated out.
本发明公开了一种基于注塑模具生产的汽车前照灯外壳,包括壳体,所述壳体的侧壁开设有储液槽,所述壳体的侧壁还开设有抽液槽,且所述储液槽与抽液槽之间连通有单向出液管,且所述单向出液管呈环形分布在壳体内,所述壳体的侧壁开设有连通储液槽与抽液槽的单向进液孔,所述抽液槽内密封滑动连接有活塞,且所述活塞通过弹簧弹性连接在抽液槽的内顶部,所述壳体的侧壁开设有回转槽,所述回转槽内安装有驱动活塞上下移动的驱动装置。本发明通过设置单向出液管、储液槽、抽液槽与活塞,并在储液槽内添加冷却液,利用驱动装置驱动活塞上下移动,可促使冷却液在循环管路中流动,从而快速的将灯壳内的热量散发出去。
