[0006] A leveling mechanism is provided on the top of the lower membrane, and the leveling mechanism includes an installation groove, a moving block, a fixed shaft, a crank, a rotating plate, a fixed rod and a leveling roller. An installation groove is opened on one side of the lower membrane, a moving block is slidably connected to the inner wall of the installation groove, a fixed shaft is threadedly connected to one side of the moving block, a crank is fixedly installed on one end of the fixed shaft, a rotating plate is fixedly installed on the outer ring of the fixed shaft, a fixed rod is fixedly installed on one side of the rotating plate, and a leveling roller is rotatably connected to one end of the fixed rod.

[0007] In one example, a screw rod penetrating through and extending outside the lower membrane is rotatably connected to one side of the inner wall of the mounting groove, and a bevel gear set is fixedly mounted on one end of the screw rod.

[0008] In one example, a second motor is fixedly mounted on one side of the lower membrane, a rotating shaft is fixedly mounted on an output shaft of the second motor, and one end of the rotating shaft is fixedly connected to a bevel gear set.

[0011] In one example, a guide rod is inserted into one side of the lifting plate, and the bottom end of the guide rod is fixedly connected to the support plate.

[0012] The production molding die of the imitation stone stainless steel manhole cover proposed by the utility model can bring the following beneficial effects:

[0013] 1. The production and forming mold of the imitation stone stainless steel manhole cover is composed of a leveling mechanism, a screw, a bevel gear set, a rotating shaft and a second motor.
