[0029] Specifically, after cooling is completed, the water pump 15 is turned off and the hydraulic rod 4 is retracted upward to drive the upper mold 5 to move upward. When demolding, the worker rotates the knob 6, and the knob 6 drives the main bevel gear 7, the secondary bevel gear 8, and the two-way threaded rod 9 to rotate. The rotation of the two-way threaded rod 9 drives the sliders 10 on the left and right sides of the outer wall to slide inward. While the sliders 10 slide, they also drive the rotating rods 11 to rotate, and then drive the demolding plate 12 to slide upward, ejecting the product from the lower mold 1, completing the demolding, reducing the time from pouring to demolding of each casting, thereby improving the overall production efficiency.

When the slider 10 slides, it will also drive the rotating rod 11 to rotate, and then drive the demolding plate 12 to slide upward, and the product is ejected from the lower mold 1 to complete the demolding.
