[0026] Specifically, a slider 202 is provided at the rear end of the adjusting rod to play a limiting role, a convex block 203 is provided at the rear end of the slider 202, and a fourth groove 204 is opened at the lower end of the convex block 203 for being connectable to the hook 5, so as to movably connect the first movable part 4 and the adjusting rod, which is beneficial to controlling the position of the adjusting rod.
[0027] Among them, as Figure 2 shown, two sliding grooves 10302 are provided on both sides of the inner wall of the first groove 103 to provide stability for the movement of the adjusting rod. Two sliding rods 205 are provided on both sides of the adjusting rod, and both are movably connected to the first sliding groove 10302. Springs 206 are provided at the rear ends of the sliding rods 205, so that the adjusting rod returns to its original position when not affected by the movement of the first moving part 4.
[0028] Embodiment 2
[0029] In order to enable the manhole cover 1 to be placed on the blanking table and automatically adjust the offset;
[0030] For the above problems, as Figure 3 and 4 shown, a second sliding groove 403 is provided on the front surface of the first moving part 4. Two third sliding grooves 404 are provided on both sides in the second sliding groove 403. The second sliding groove 403 and the third sliding groove 404 provide a moving space for the second moving part 501. The second moving part 501 is movably connected in the third sliding groove 404. The front end of the second moving part 501 is movably connected to a hook 5 and is movably connected to the fourth groove 204. The fourth groove 204 is used to connect with the hook 5. A moving rod 401 is provided in each of the four first moving parts 4, and a return spring for resetting is provided in the moving rod 401. A push rod 402 is provided on one side of the first moving part 4 for contacting the ejector rod 301 and being controlled by the ejector rod 301. Ejector rods 301 are provided at the upper ends of the pressing blocks 3 and extend into the third groove 104 through the first groove 103. Springs 302 are provided between the pressing blocks 3 and the third groove 104.
[0031] Working principle: When in use, the manhole cover mold 1 is placed at the designated raw material blanking position. When the manhole cover mold 1 is placed on a plane and is subjected to force, the pressing block 3 located at the lower end of the well edge 101 is received in the third groove 104 under the action of the extrusion force. Since the pressing block 3 squeezes upward, the ejector rod 301 fixed at the upper end extends along the first groove 103 under the action of the force and is connected to the push rod 402 of the first moving part 4 at the front end. Therefore, under the pushing action of the ejector rod 301, the first moving part 4 rotates around the moving rod 401 as the axis. As Figure 3 and Figure 4 shown, the first moving part 4 drives the front hook 5 and the second moving part 501 to move along the second sliding groove 403 and the third sliding groove 404, and pushes the adjusting rod of the adjusting assembly 2 to extend out of the second groove 10301. By adjusting the distance between the well edge 101 and the surrounding components to be the same, the position of the manhole cover mold 1 is adjusted to ensure that the raw materials fall smoothly into the manhole cover mold 1. After receiving the materials, when the current manhole cover mold 1 is taken away, the pressing block 3 returns to its original position through the spring 302 in the non-loaded state, and the first moving part 4 and the adjusting rod are sequentially retracted to their original positions.
