Description

Technical Field

[0001] The utility model belongs to the technical field of casting molds, in particular to a cement manhole cover casting mold. Background Art

[0002] Currently, many circular cement manhole covers are found on urban roads. While these covers are sturdy and durable, plastic molds are often used during the casting process, making them susceptible to damage. Furthermore, the finished covers are difficult to remove from the mold, adding significant inconvenience to the casting process. A search revealed patent application number 201520554878.X, which discloses a casting mold for cement manhole covers. The mold comprises a main body with an air hole at the center of its bottom and a mesh anti-skid groove on its bottom surface. The finished manhole cover has an anti-skid surface, and a columnar body is welded to its bottom surface.

[0003] However, during actual use, the applicant found that when removing the cast cement manhole cover from the main body, since the bottom of the cement manhole cover fits with the bottom of the inner side of the main body, there is a lack of a starting point. The main body and the cement manhole cover inside it need to be flipped 180° together to pour the cement manhole cover out of the main body, which is not convenient to operate. In view of this, we propose a cement manhole cover casting mold. Utility Model Content

A step groove is provided at the center position of the top of the casting platform 11, and a jacking seat 6 is provided in the step groove. The top of the casting platform 11 on the front and rear sides of the jacking seat 6 is symmetrically fixed with a columnar body 12. The bottom of the jacking seat 6 is fixedly connected with a guide frame 10, and the guide frame 10 slides along the rectangular slide groove provided inside the cement manhole cover casting membrane seat 1. The internal movement of the guide frame 10 is provided with a cam 9, and the cam 9 is sleeved and fixed on the rotating shaft 7. The rotating shaft 7 is rotatably connected to the cement manhole cover casting membrane seat 1 through a bearing, and the front end of the rotating shaft 7 extends to the outside of the cement manhole cover casting membrane seat 1 The lever arm 8 is sleeved and fixed, and the arc membrane frame 5 is driven to move in the direction away from the lifting seat 6 by rotating the bolt 4, so that the arc membrane frame 5 is separated from the cement manhole cover, which is convenient for personnel to demould the cement manhole cover. The cam 9 is driven to rotate by rotating the rotating shaft 7, and the cam 9 can lift the lifting seat 6 upward, and lift the cast cement manhole cover through the lifting seat 6, so that the bottom of the cement top cover is separated from the casting platform 11, so that it is convenient for personnel to take out the cast cement manhole cover. When pouring the cement manhole cover, the screw 3 can be rotated forward to drive the moving seat 2 together with the arc membrane frame 5 to move toward the middle until the ear 21 abuts against the limit block 13, so that the two arc membranes The frames 5 are combined into a complete circular ring, and then cement can be poured inside the circular ring enclosed by the two arc-shaped membrane frames 5, and the cement on the top is smoothed. After the cement manhole cover is formed, the screw 3 is rotated in the opposite direction to drive the movable seat 2 and the arc-shaped membrane frame 5 to reset and move, so that the arc-shaped membrane frame 5 is separated from the cement manhole cover. Then, the tail end of the lever arm 8 is held and pressed downward. At this time, the lever arm 8 can drive the rotating shaft 7 together with the cam 9 to rotate clockwise. The rotation of the cam 9 can lift the guide frame 10 together with the lifting seat 6 upward, and then the cast cement manhole cover is lifted up by the lifting seat 6, so that the bottom of the cement manhole cover is separated from the casting platform 11, and the cement manhole cover can be taken out.

[0022] Embodiment 2: The difference between this embodiment and embodiment 1 is that the tail of the screw rod 3 is fixedly connected to the movable seat 2 by a bolt 4, and a connecting protrusion 22 is provided on the movable seat 2 away from the screw rod 3. The tail of the arc-shaped membrane frame 5 is provided with a connecting groove 51, and the connecting protrusion 22 is matched with the connecting groove 51 for connection. The lower end of the bolt 4 passes through the top of the tail end of the arc-shaped membrane frame 5 and is screwed into the threaded hole opened at the top of the connecting protrusion 22. By unscrewing the bolt 4, the arc-shaped membrane frame 5 and the movable seat 2 can be disassembled, so that different straight membrane frames can be replaced. The curved membrane frame 5 of different diameters can be used to cast cement manhole covers of different diameters, which is more practical. When casting cement manhole covers, the curved membrane frame 5 with a suitable diameter can be selected according to the size of the cement manhole cover to be cast, and the connecting groove 51 is docked with the connecting protrusion 22, so that the connecting protrusion 22 is inserted into the connecting groove 51, and finally the lower end of the bolt 4 is passed through the top of the connecting groove 51 and screwed into the connecting protrusion 22, so that the curved membrane frame 5 of the required diameter can be fixed on the movable seat 2, so as to realize the casting of cement manhole covers of the required diameter.

[0023] Working principle: When pouring cement manhole cover, the screw rod 3 can be rotated forward to drive the movable seat 2 and the curved membrane frame 5 to move toward the middle until the ear 21 abuts against the limit block 13, so that the two curved membrane frames 5 are merged into a complete circular ring, and then cement can be poured inside the circular ring enclosed by the two curved membrane frames 5, and the cement on the top is smoothed. After the cement manhole cover is formed, the screw rod 3 is rotated in the opposite direction to drive the movable seat 2 and the curved membrane frame 5 to reset and move, so that the curved membrane frame 5 is separated from the cement manhole cover, and then the tail end of the lever arm 8 is held and pressed downward. At this time, the lever arm 8 can drive the rotating shaft 7 to rotate clockwise together with the cam 9, and the cam 9 rotates. The kinetic energy can lift the guide frame 10 together with the lifting seat 6, and then lift the cast cement manhole cover through the lifting seat 6, so that the bottom of the cement manhole cover is separated from the casting platform 11, and the cement manhole cover can be taken out. When casting the cement manhole cover, you can also select an arc-shaped membrane frame 5 with a suitable diameter according to the size of the cement manhole cover to be cast, and dock the connecting groove 51 with the connecting protrusion 22, so that the connecting protrusion 22 is inserted into the connecting groove 51, and finally the lower end of the bolt 4 passes through the top of the connecting groove 51 and is screwed into the connecting protrusion 22, so that the arc-shaped membrane frame 5 of the required diameter can be fixed on the movable seat 2, thereby realizing the casting of the cement manhole cover of the required diameter.
