The top of one side of the pressure plate 1 is rotatably connected to a rotating shaft 1, and a spur gear 3 22 is fixedly connected to the outer wall of the rotating shaft 1.

The double-groove pulley 2 32 and the double-groove pulley 1 162 are connected through a belt three transmission. The rotation of the four rubber rollers 31 can make the two molds 4 rotate between the two pressing plates 1, so that the concrete in the two molds 4 can do centrifugal motion, so that the concrete can be evenly spread out to form the shape of a drainage pipe. Both ends of the inner wall of the pressing plate 1 are fixedly connected with a half T-shaped ring 18, and the mold 4 tightly attached to the four rubber rollers 31 is rotatably connected between the two half T-shaped rings 18 at relative positions, so that the four rubber rollers 31 can drive the two molds 4 to rotate.
[0027] Working principle: when in use, firstly, four rubber rollers 31 are rotated by an external driving device, and the rotating rubber rollers 31 can make the two molds 4 rotate, and then concrete is poured into the two molds 4, and the concrete inside is subjected to centrifugal motion by the rotation of the two molds 4, so that the concrete can be evenly spread to form the shape of a drainage pipe. When the concrete is dry and the sides of the two molds 4 that are close to each other are parallel to the ground, the drainage pipe needs to be taken out from between the two molds 4, and at this time, one of the spur gears 3 22 can be driven to rotate by an external driving device. Since the two spur gears 3 22 are meshed with each other, the two spur gears 3 22 rotate at the same time, and the rotating spur gear 3 22 can make the single-groove pulley 1 221 drive the single-groove pulley 2 23 at the corresponding position to rotate, and the rotating single-groove pulley 2 23 can make the incomplete gear 231 at the corresponding position drive the circular frame 24 at the corresponding position to move back and forth up and down, and the circular frame 24 that moves back and forth up and down can make the rack 3 242 at the corresponding position drive the spur gear 2 Gear 212 rotates, and the rotating spur gear 212 can make multiple protrusions 211 at corresponding positions rotate. Since the rack 3 242 moves up and down, the multiple protrusions 211 rotate back and forth between counterclockwise and clockwise. The multiple rotating protrusions 211 can knock the mold 4 at the corresponding position, so that the drainage pipes in the two molds 4 are separated from the inner walls of the two molds 4 by the adsorption state, and then the rack 171 can be moved by starting the hydraulic cylinder 17. The moving rack 171 can make the spur gear 161 drive the upper pressure plate 1 to rotate along the axis of the two connecting shafts. Since the double-groove pulley 162 is rotationally connected to the connecting shaft at the corresponding position, the rotation of the upper pressure plate 1 will not drive the double-groove pulley 162 to rotate. Since the two molds 4 are stuck between the pressure plate 1 at the corresponding position and the two half T-rings 18 at the corresponding position, the rotation of the upper pressure plate 1 will drive the mold 4 at the corresponding position to rotate until the sides of the two pressure plates 1 are against each other. At this time, the dried concrete drain pipe can be taken out. The device uses multiple protrusions 211 to knock on the mold 4 to achieve the separation of the drain pipe from the mold 4. No manual knocking is required, which can reduce the physical exertion of workers and improve the efficiency of drain pipe demoulding. In addition, the device does not need to use a large crane to demould the mold 4, thereby preventing the shaking of the mold 4 from causing collisions with the drain pipe, thereby improving the efficiency of drain pipe demoulding.
