If the casting is taken out from the moving die, long distance core pulling is needed according to the shape of the casting, so the mechanism of the sliding block which rotates midway was designed.

根据铸件形状特点，若在动模内取出铸件，需长距离抽芯，故设计了滑块中途自行转动机构。

The working principle of the die casting mould has been discussed, and the core pulling force, the core pulling distance and the diameter of the angle pin have been confirmed by calculation.

论述了壳体铸件压铸模工作原理，通过计算确定了抽芯力和抽芯距离以及斜销直径。
