[0024] A skirt is provided at the outer bottom end of the container 2, and the skirt of the container 2 is bolted to the mounting frame 1. When the container 2 is working, the position of the container 2 can be limited to prevent the container 2 from being displaced.
[0025] A sealing gasket 8 is sleeved on the outer side of the top end of the hydraulic rod Ⅱ5 and located below the push plate 7. A sealing groove is provided at the inner bottom end of the container 2 and located in the moving path of the sealing gasket 8. The size of the sealing gasket 8 is adapted to the size of the sealing groove of the container 2. A plurality of openings are provided on the side of the sealing groove of the container 2, and the plurality of openings are arranged at equal angles on the side of the sealing groove. When the sealing gasket 8 moves upward, the liquid inside the container 2 fills the inner side of the sealing groove of the container 2. When the sealing gasket 8 is below the sealing gasket 8, the sealing groove of the liquid oil sealing gasket 8 can be discharged by moving the sealing gasket 8 downward, wherein a through hole for slidingly installing the hydraulic rod Ⅱ5 is provided in the middle of the sealing groove of the container 2, and the outer size of the sealing gasket 8 is larger than the size of the through hole of the container 2.
[0026] The upper cover includes a cover and a cover plate 3 at the top of the container 2, a sealing ring 6 which is sleeved on the outside of the bottom end of the cover plate 3 and inserted into the inside of the container 2. This structure can make the top of the container 2 open and close more conveniently. At the same time, the hydraulic system pressure of the hydraulic rods Ⅰ4 and Ⅱ5 is greater than the pressure used inside the container 2, so as to avoid pressure leakage caused by excessive pressure inside the container 2.
[0027] The bottom end of the container 2 is provided with a closing pad 9 which is sleeved on the outside of the hydraulic rod II5 and connected to the mounting frame 1. The closing pad 9 is installed between the container 2 and the mounting frame 1 to further seal the container 2 and the hydraulic rod II5.

[0029] Working principle:
[0030] When in use, the sealed mold with magnetic powder is placed in the liquid inside the container 2, so that the hydraulic rod I4 drives the cover plate 3 to cover the container 2 and seal it through the sealing ring 6, and the hydraulic rod II5 drives the push plate 7 to move downward, so that the sealing gasket 8 is subjected to pressure under the push plate 7, thereby improving the seal between the hydraulic rod II5 and the container 2, so that the hydraulic system presses the powder inside the mold into shape through the liquid, and opens the upper cover through the hydraulic rod I4. At the same time, the hydraulic rod II5 drives the push plate 7 to move upward, so that the upper surface of the push plate 7 is flush with the top of the container 2, and the surface of the push plate 7 is mesh-shaped, so that the mold can be drained before being taken out, making the unloading work more convenient.
