[0002] Concrete pipe piles play an important role in supporting, protecting and fixing structures in engineering construction. They are widely used in various fields such as civil engineering, water conservancy engineering, transportation engineering and environmental engineering. The precise design and demoulding characteristics of the mold can ensure the consistency of the size and shape of each concrete pipe pile, reduce product deformation or damage caused by poor molds, and ensure the stability of product quality.

[0003] After searching, the mold for producing concrete pipe piles with announcement number CN216422984U, which is easy to demould, includes: two half-tubes, multiple inner ring plates and multiple driving mechanisms. The two half-tubes are connected into a circular tube, and the multiple inner ring plates are respectively installed in the two half-tubes for horizontal sliding. The mold for producing concrete pipe piles provided by the utility model is composed of two half-tubes to form a pipe pile mold. Cast-in-place operation is carried out in the circular tube composed of the two half-tubes. When the mold needs to be demoulded after the operation, the inner ring plate is moved toward the center of the half-tube through the driving mechanism, thereby pushing the half-tube to move to the side away from the pipe pile, so that the half-tube is separated from the pipe pile, reducing the demoulding difficulty, reducing the demoulding time, and speeding up the construction progress. Through the lifting connecting rod, all handle frames can be conveniently driven to be linked and rotated to a certain angle, saving the time of rotating the handle frames separately, thereby saving demoulding time;

The top of the slider 5 is fixedly connected to a semicircular mold 6, the inner wall of the semicircular mold 6 is slidably connected to a sliding frame 7, the opposite end of the sliding frame 7 is fixedly connected to a second motor 8, the driving end of the second motor 8 penetrates the inner wall of the sliding frame 7 and is fixedly connected to a threaded screw 9, the bottom end of the slider 5 is slidably connected to the left and right parts of the lower side of the inner wall of the base 1, the outer walls of the threaded screw 9 are respectively threadedly connected to the inner wall of the semicircular mold 6, and the opposite end of the sliding frame 7 is fixedly connected to a stripping plate 10, and the diameter of the stripping plate 10 is equal to that of the semicircular mold 6.

[0026] Specifically, when the molding process needs to be demolded, the clamping rod 14 is first removed from the through hole 12 to release the limit on the connecting plate 11 and the semicircular mold 6. At the same time, the first motor 3 is controlled to reverse, driving the semicircular mold 6 to move outward, and the second motor 8 is started. The second motor 8 drives the threaded screw 9 to rotate, so that the threaded screw 9 rotates on the inner wall of the semicircular mold 6, and drives the sliding frame 7 to move inward, and drives the demolding plate 10 to move inward to demold the concrete pipe pile.

[0028] Specifically, the worker can pull the clamping ring 15 to the right through the fixing plate 17, remove the clamping ring 15 from the limiting ring 18, and then rotate the connecting rod 13.

The connecting rod 13 drives the clamping rod 14 to rotate, align the clamping rod 14 with the through hole 12, and drive the semicircular mold 6 to move completely closed by the first motor 3, and then clamp the clamping rod 14 into the through hole 12, and then rotate the connecting rod 13, clamp the clamping rod 14 on the left side of the left connecting plate 11, and then release the fixing. Plate 17, through the spring 16, moves the clamping ring 15 to the left, and clamps the clamping ring 15 into the limiting ring 18, limits the connecting rod 13 and the clamping rod 14, and completes the limiting of the connecting plates 11 on both sides and the semicircular mold 6, and then pours concrete inward. When the molding needs to be demoulded, first remove the clamping rod 14 from the through hole 12 to release the limiting of the connecting plate 11 and the semicircular mold 6, and at the same time control the first motor 3 to reverse, drive the semicircular mold 6 to move to the outside, and start the second motor 8.
