[0024] When in use, apply demoulding liquid to the inside of the upper mold groove 8, the outside of the lower module 13 and the top of the lower mold 12, and then start the two hydraulic cylinders 6 through the external controller to drive the movable plate 5 and the upper mold 7 to move downward as a whole until the upper mold 7 is tightly fitted with the lower mold 12. At this time, the lower module 13 is located inside the upper mold groove 8, and then the external material pouring pipe is connected to the injection pipe 10, and the external booster pump is connected to the booster pipe 11 to pour the material and increase the pressure in the upper mold groove 8, so that the material fills the area between the inner wall of the upper mold groove 8 and the outer side of the lower module 13, so that the material is formed into a shell.

[0025] In summary, the booster casting mold for shell casting drives the two first threaded rods 176 to rotate by turning the two first hand wheels 179, thereby driving the two traction blocks 177, the two sliders 173 and the two first positioning blocks 174 to move in opposite directions, so that the two first positioning blocks 174 are respectively moved out from the inside of the two first positioning grooves 16, thereby releasing the position restriction on the upper mold 7. At this time, the upper mold 7 can be pulled downward to be removed. Secondly, the second hand wheel 264 can be turned to drive the rotating shaft 261 and the driving bevel gear 262 to rotate, and then the second threaded rod 21 is driven to rotate through the driven bevel gear 263, and the second threaded rod 21 During the rotation, the two moving blocks 23 and the two second positioning blocks 25 will be driven to move in opposite directions, so that the two second positioning blocks 25 are respectively moved out from the inside of the two second positioning grooves 24, thereby releasing the position restriction of the extension block 19. At this time, the lower mold 12 can be pulled upward to remove it, and finally the purpose of facilitating the disassembly of the supercharged casting mold is achieved, and then the maintenance or replacement of the supercharged casting mold is facilitated, which solves the problem that during the use of the existing supercharged casting mold, most of the casting molds are directly fixed on the casting device, so it is inconvenient to disassemble the casting mold, resulting in great inconvenience in maintaining or replacing the casting mold.
