When the hydraulic cylinder drives the upper casting mold bin to lift and lower, the impact can be effectively absorbed to avoid damage to the mold caused by rigid collision; the upper die casting bin is fixedly connected to the top of the fixed plate through the connecting pieces at the four corners by a bolt and nut assembly, which is convenient for quick disassembly, installation and maintenance of the upper casting mold bin, and the setting of the liquid inlet pipe is beneficial to the accurate injection of the casting liquid.

[0015] In the lifting component of the present invention, the cylinder is set to drive the second connecting rod to rotate around the first connecting rod, the second connecting rod drives the rotating rod to lift and lower, so as to drive the pressing column to lift and lower. The pressing column is slidably connected to the chute frame of the first connecting rod through a T-shaped chute, so as to provide guidance and limit for the lifting and lowering of the pressing column. The lifting and lowering of the pressing column drives the third connecting rod to rotate around the rotating frame, so that the other end of the connecting rod drives the moving plate to lift and lower, so as to realize the lifting. In this way, using the lever principle, with the rotating frame as the fulcrum, when the cylinder drives the lifting component, the third connecting rod amplifies the acting force by means of the lever to realize the efficient lifting and lowering of the moving plate and the limiting pile. The sliding fit between the T-shaped chute and the chute frame ensures the accurate movement track of the lever and avoids shaking.
