[0021] Referring to Figure 2 With Figure 4 As shown in the embodiment, the surface of the bottom of the mould core body 1 is sleeved with a sealing gasket 7, the bottom of the nut block 6 is fixedly connected with a rubber pad 8, and the bottom of the casing 2 is provided with an inclined groove 9. By moving the bottom plate 3 downward on the surface of the mould core body 1, the bottom of the bottom plate 3 is tightly attached to the surface of the sealing gasket 7, the sealing gasket 7 is deformed to tightly attach to the bottom plate 3, the sealing property of the casing 2 and the bottom of the mould core body 1 is improved, and then the nut block 6 is moved downward to push the rubber pad 8 into the inclined groove 9, the bottom of the rubber pad 8 is tightly attached to the inner wall of the inclined groove 9, and the inclined shape of the inner wall of the inclined groove 9 causes the rubber pad 8 to gradually incline inward, tightly attaching to the surface of the mould core body 1, improving the sealing property of the top of the casing 2 and the mould core body 1, and preventing the water flow in the casing 2 from leaking out.
[0022] Referring to Figure 2 With Figure 4 As shown in the embodiment, the top of the casing 2 is provided with a circular groove 10, the bottom of the nut block 6 is fixedly connected with a circular plate 11, and the surface of the circular plate 11 is slidably connected to the inner wall of the circular groove 10.
