When the invention is used, a worker sequentially places the third die 19, the second die 18 and the first die 17 in the mounting groove 14 at the top of the mounting column 10, and when the invention is used, the outer walls of the first die 17, the second die 18 and the third die 19 are polygonal, so that when the invention is used, the outer walls of the three dies are mutually abutted with the inner walls of the polygonal mounting groove 14. When the staff installs three moulds, can make accurate correspondence between the three moulds, and the outer wall of three moulds and the inner wall mutual butt of mounting groove 14 when using, can make the installation of three moulds more stable when using. The outer wall of the mounting post 10 and the inner wall of the protective housing 1 are connected and supported by four support plates 16 in use, and the four support plates 16 can divide the space between the mounting post 10 and the inner wall of the protective housing 1 into four storage cavities in use.

When the staff takes the cooled aluminum alloy shell, the staff rotates the top cover 2, the top cover 2 drives the external thread blocks 26 to move out of the installation groove 14, the reinforcing plate 4 and the lifting plate 3 are pulled to move upwards on the side face of the protective shell 1 through the hydraulic cylinder 6, when the lifting plate 3 moves upwards, the protective shell 1 gradually descends towards the ground, and simultaneously, the ground pushes the bottom ends of the support rods 8 when the protective shell 1 moves downwards, so that the support rods 8 slide towards the installation groove 14 in the guide holes 24. When the aluminum alloy shell is used, the top ends of the support rods 8 sequentially push the third die 19, the second die 18 and the first die 17 to move upwards in the mounting groove 14 until the first die 17 moves out of the mounting groove 14, and when the first die 17 is disassembled by a worker, the aluminum alloy shell in the top model groove 20 of the second die 18 can be taken. After the worker finishes taking the aluminum alloy shell on the second mold 18, the protective shell 1 can be moved down again through the hydraulic cylinder 6, so that the support rod 8 pushes the third mold 19 again until the second mold 18 moves out of the mounting groove 14, and the worker can take the aluminum alloy shell inside the top mold groove 20 of the third mold 19 after the worker finishes removing the second mold 18.
