[0025] When the staff needs to make the aluminum ingot casting mold pop out of the inside of the lower mold 1, the second motor 16 is turned on. The second driving gear 19 is driven to rotate through the sleeve block 6. Through the tooth engagement between the second driving gear 19 and the second driven gear 18, the second driven gear 18 is driven to rotate by the second driving gear 19. Then, the second threaded rod 15 is driven to rotate inside the threaded sleeve 12 by the second driven gear 18. Through the cooperation between the second threaded rod 15 and the threaded sleeve 12, the threaded sleeve 12 moves upward inside the limiting box 17. Then, the top plate 11 is driven by the threaded sleeve 12 to slowly rise inside the lower mold 1. The made aluminum ingot casting mold is slowly pushed out of the inside of the lower mold 1 by the top plate 11, thus completing the ejection of the aluminum ingot casting mold.

The second driving gear 19 is driven to rotate through the sleeve block 6. The second driven gear 18 is driven to rotate by the second driving gear 19. Then, the second threaded rod 15 is driven to rotate inside the threaded sleeve 12 by the second driven gear 18, so that the threaded sleeve 12 moves upward inside the limiting box 17. Then, the top plate 11 is driven by the threaded sleeve 12 to slowly rise inside the lower mold 1. The made aluminum ingot casting mold is slowly pushed out of the inside of the lower mold 1 by the top plate 11. Compared with the traditional device, this device is convenient to drive the top plate 11 to slowly push out the aluminum ingot casting mold in the lower mold 1 through the cooperation between the threaded sleeve 12 and the second threaded rod 15, greatly improving the product quality and effectively reducing the defects of scratches and depressions on the surface of the casting caused by too fast ejection, avoiding the severe friction and impact between the casting and the mold during high-speed ejection.
