[0011] Preferably, the bottom of the lower mold is provided with a guide sleeve that slides with the top block.

[0012] Preferably, a U-shaped seat is provided at the end of the cylinder shaft; the U-shaped seat and the end of the linkage rod are rotatably connected by a fourth pin.

[0013] Preferably, a hydraulic cylinder is installed on the rear side of the base, and the upper end of the hydraulic cylinder is connected to the upper mold via a connecting block.

[0014] Preferably, the lower mold has a lower extension plate at its upper end, and the lower extension plate has a stepped groove; the upper mold has an upper extension plate at its lower end that can be embedded in the stepped groove, and the upper mold has a pouring gate at its upper end.

[0015] Preferably, the base has multiple support feet at its bottom, a recess for mounting the cylinder is provided on the base, rotating grooves are provided on both sides of the recess, and convex shafts rotating in the rotating grooves are provided at both ends of the cylinder.

[0016] According to the above technical solution, this utility model provides a magnesium ingot casting device, which includes a base, a lower mold, and an upper mold. The lower mold is fixed to the base by multiple columns, forming a bottom space between the lower mold and the base. Multiple ejection holes are arranged along the length of the bottom surface of the lower mold. A top block is slidably disposed in the ejection hole. A push rod is rotatably connected to the bottom of the top block. A bearing seat is provided on the base at each ejection hole. A horizontal shaft is provided on the bearing seat. A rocker arm is rotatably disposed on the horizontal shaft. The upper end of the rocker arm is rotatably connected to the lower end of the push rod.

The cylinder shaft is rotatably connected to the end of the linkage rod.

[0017] This magnesium ingot casting device performs conventional casting after the upper and lower molds are closed. After casting is completed, the upper mold is opened, and a cylinder pushes a linkage rod to move horizontally. Under the push of the linkage rod, the lower ends of multiple swing rods swing around the horizontal axis, which in turn pushes the upper ends of the swing rods to move the push rod. The push rod pushes the top block upward, causing multiple top blocks to push the cast product upward at different positions, thus achieving demolding. Especially for longer cast products, demolding by pushing upward at multiple points can avoid the problem of one end of the cast product being biased and difficult to demold, thereby improving the demolding efficiency of the cast product.

[0029] Through the implementation of the above technical solution, the magnesium ingot casting device performs conventional casting after the upper and lower molds 1 are closed. After casting is completed, the upper mold 2 is opened, and the linkage rod 7 is moved horizontally by the cylinder 14. Under the push of the linkage rod 7, the lower ends of multiple swing rods 10 swing around the horizontal axis 6, thereby causing the upper ends of the swing rods 10 to push the push rod 11 to move. The push rod 11 pushes the top block 20 upward, so that multiple top blocks 20 push the cast product upward at different positions, realizing demolding. Especially for longer cast products, demolding by pushing upward at multiple points can avoid the problem of one end of the cast product being biased and difficult to demold, thus improving the demolding efficiency of the cast product.
