[0026] Working principle: The screw 5 is driven to rotate by the motor 9 or manually rotating the manual adjustment disk 7. After the screw 5 rotates, the sleeve 3 is affected by the rotating thread to move vertically. During the movement of the sleeve 3, the top plate 2 is driven. After the top plate 2 moves up, the cavity 21 is exposed. After the surface of the cavity 21 is cleaned, the top plate 2 is reset and casting is carried out through the casting port 13. After the casting is cooled, the top plate 2 is moved up. During the upward movement, the positioning plate 12 pushes the limit block 15 to move up, so that the molded material is pushed by the push plate 20 to achieve the effect of rapid unloading. The material after unloading continues to move up to the mouth of the cavity 21, and then is removed for the next processing.

[0027] The components of the utility model, including 1, base; 2, top plate; 3, sleeve; 4, scale; 5, screw; 6, connecting plate; 7, manual adjustment disk; 8, transmission cavity; 9, motor; 10, fixing frame; 11, slide groove; 12, positioning plate; 13, casting port; 14, spring; 15, limit block; 16, connecting rod; 17, push rod; 18, support rod; 19, movable cavity; 20, push plate; 21, cavity; 22, sprocket; 23, chain; 24, manual adjustment rod, are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. The problem solved by the utility model is that the existing leak plate casting mold is not convenient for adjusting the thickness of the leak plate, and it is difficult for staff to calibrate and implement casting. The problem of cumbersome manual demoulding operation after casting and cooling is solved. The utility model combines the above-mentioned components with each other. The top plate 2 of the cavity 21 of the utility model can be adjusted in height by a height adjustment mechanism to adjust the height of the cavity 21, thereby adjusting the thickness of the leak plate.

The manual adjustment disk 7 can also be used to drive the screw 5 to rotate, thereby performing manual adjustment. The adjusted height can be known by observing the scale 4, which is convenient for workers to operate. At the same time, after the sleeve 3 drives the top plate 2 to move continuously upward, the positioning plates 12 on both sides of the sleeve 3 move upward at the same time and push the limit block 15. After the limit block 15 moves upward, it drives the push rod 17 and the support rod 18 to move upward, and the molded material is demoulded by the push plate 20, thereby increasing the demoulding speed and reducing the difficulty of demoulding.
