So that lower mould 5 and upper mould 9 are formed to casting, it is convenient to quickly form casting to the casting;

[0028] Specific as Figure 1 、 Figure 2 And Figure 4As shown, the fixed plate 2 is fixedly connected to the inner side of the lower end of the workbench 1, the drive motor 12 is fixedly arranged at the middle side of the lower end of the fixed plate 2, the movable mounting rod 13 is connected to the output end of the drive motor 12, the moving connection plate 14 is movably connected to the outer side of the movable mounting rod 13, and the drive cylinder 10 is started after the castings are quickly formed. The drive cylinder 10 drives the connecting plate 15 to slide upward, so that the connecting plate 15 drives the mounting plate 8 to slide upward under the action of the upward sliding of the connecting plate 15, and then the mounting plate 8 drives the upper mold 9 to separate from the inner side of the lower mold 5. The drive motor 12 arranged at the middle side of the lower end of the fixed plate 2 is started, so that the movable mounting rod 13 connected to the output end of the drive motor 12 rotates under the driving action of the drive motor 12. Thus, the movable mounting rod 13 and the moving connection plate 14 are threadedly connected under the rotating action of the movable mounting rod 13. Then, the moving connection plate 14 slides downward under the thread action between the movable mounting rod 13 and the moving connection plate 14. The moving connection plate 14 drives the mounting moving rod 3 to slide upward under the upward moving action of the moving connection plate 14.

The mounting plate 8 is manually pulled forward, so that the mounting plate 8 slides forward under the pulling action. Thus, the mounting plate 8 drives the fixed block 16 to slide forward at the outer side of the upper end of the connecting plate 15 under the forward sliding action of the mounting plate 8. Then, the mounting plate 8 separates from the outer side of the lower end of the connecting plate 15 under the forward sliding action of the fixed block 16, which facilitates the disassembly and replacement of the mounting plate 8, and thus facilitates the disassembly and replacement of the upper mold 9.
