Two second telescopic plates 45 on both sides of one end, four docking plates 46 whose one end is hinged on both sides of the horizontal ends of the two connecting plates 35 and the other ends are connected to the two first telescopic plates 42 and the two second telescopic plates 45 on the outside of the pipe segment mold body 2, and four avoidance long strip holes 47 are respectively arranged on both sides below the end surfaces of the two ends of the pipe segment mold body 2 for the movement of the two first telescopic plates 42, the two second telescopic plates 45 and the four docking plates 46; the four docking plates 46 are arranged obliquely; the hydraulic cylinder 5 is located between the two top plates 43 and the output end is used to push the driving plate 41 to move toward one end of the pipe segment mold body 2.

[0021] Furthermore, a gap is left between the two sealing cover plates 34 to facilitate concrete injection.

[0022] Furthermore, the two first telescopic plates 42 and the two second telescopic plates 45 are each provided with a support block 6 on a section inside the segment mold body 2; the bottoms of the four support blocks 6 are all connected to the bottom of the segment mold body 2, making the telescopic movement more stable.

[0023] When in use: when opening and closing the two sealing cover plates 34, first start the hydraulic cylinder 5 to drive the output end to retract, and then the output end of the hydraulic cylinder 5 drives the driving plate 41 to move toward the hydraulic cylinder 5, and then the driving plate 41 drives the first telescopic plate 42 to retract into the pipe segment mold body 2, and at the same time the driving plate 41 drives the top plate 43 to move toward one end of the pipe segment mold body 2, and then the top plate 43 pushes one end of the rotating plate 44 to rotate toward one end of the pipe segment mold body 2, and then the other end of the rotating plate 44 rotates toward the direction of the hydraulic cylinder 5. Since one end of the second telescopic plate 45 is hinged on the other end of the rotating plate 44, the rotating plate 44 drives the second telescopic plate 45 to retract into the pipe segment mold body 2, and then the first telescopic plate 42 and the second telescopic plate 45 drive the inclined docking plate 46 to move toward one end of the pipe segment mold, and then one end of the docking plate 46 pulls the bottom horizontal end of the connecting plate 35. Since the vertical end of the connecting plate 35 is connected to the bottom surface of the horizontal end of the sealing cover plate 34, and the horizontal end of the sealing cover plate 34 is connected to the fixed plate 3 3 is connected to the driving rod 32, so when the docking plate 46 pulls the connecting plate 35, the connecting plate 35 drives the horizontal end of the density cover plate to flip clockwise, and then the density cover plate covers one end side of the pipe segment mold body 2 and flips upward, and then the pipe segment mold body is opened and closed. When it needs to be closed, the hydraulic cylinder 5 is started to extend the output end to drive the driving plate 41 to move. The driving plate 41 drives the first telescopic plate 42 to extend out of the pipe segment mold body 2. At the same time, the driving plate 41 drives the top plate 43 to return to its original position, and then the top plate 43 pulls the rotating plate 44 to move and rotate in the opposite direction, and then the other end of the rotating plate 44 pushes the second telescopic plate 45 to extend out of the pipe segment mold body 2, and then the first telescopic plate 42 and the second telescopic plate 45 drive the docking plate 46 to move away from the pipe segment mold body 2, and then one end of the docking plate 46 pushes one end of the connecting plate 35 to flip counterclockwise, and then the connecting plate 35 drives the sealing cover plate 34 to flip counterclockwise. When the sealing cover plate 34 covers the top surface of the pipe segment mold body 2, it stops, and the closing is completed.

[0024] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
