Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 The utility model provides a technical solution: a steel mold for producing post-tensioned prestressed concrete pipe piles, comprising a lower mold 1, a steel cage 3 is installed inside the lower mold 1, an upper mold 2 is installed on the upper surface of the lower mold 1, a positioning device 4 is provided on the surface of the lower mold 1, and a smoothing device 5 is provided on the side of the lower mold 1 close to the upper mold 2.

[0032] The specific arrangement and function of the positioning device 4 and the smoothing device 5 will be described in detail below.

[0033] like Figure 1 and Figure 2 as well as Figure 3 As shown, the positioning device 4 includes four connecting bars 401, and the four connecting bars 401 are all slidably connected to the inner wall of the lower mold 1. The ends of the four connecting bars 401 away from the lower mold 1 are fixedly connected to a rectangular plate 402, and the upper surface of the rectangular plate 402 is slidably connected to a push plate 403, and the side of the push plate 403 close to the lower mold 1 is fixedly connected to a pad 404. The rectangular plate 402 can be connected to the lower mold 1 through the connecting bars 401, and the push plate 403 slidably connected to the rectangular plate 402 can be moved. The pad 404 can be moved by moving the push plate 403, and the position of the upper mold 2 can be adjusted when the lower mold 1 and the upper mold 2 are connected by the push plate 403 and the pad 404. The side of the push plate 403 away from the pad 404 is fixedly connected to a handle 405, and the side of the connecting bar 401 away from the lower mold 1 is fixedly connected to a first arc plate 406. The position of the push plate 403 can be conveniently moved through the handle 405 , and the position of the connecting bar 401 can be fixed through the first arc-shaped plate 406 .

[0034] Four second curved plates 407 are fixedly connected to the surface of the lower mold 1, and a pull rod 408 is slidably connected to the inner wall of the first curved plate 406. The pull rod 408 slidably connected to the inner wall of the first curved plate 406 can move, and the position of the first curved plate 406 can be limited by the pull rod 408 and the second curved plate 407. A pull plate 409 is fixedly connected to one end of the pull rod 408 away from the second curved plate 407, and a spring 410 is sleeved on the surface of the pull rod 408, and the two ends of the spring 410 are fixedly connected to the first curved plate 406 and the pull plate 409 respectively. The pull plate 409 can facilitate the movement of the pull rod 408, and the spring 410 can limit the position of the pull rod 408.

[0035] like Figure 2 and Figure 4 as well as Figure 5 As shown, the smoothing device 5 includes two mounting bars 51, both of which are mounted on the side of the lower mold 1 close to the upper mold 2, and a concave arc strip 53 is mounted on the side of the two mounting bars 51 close to each other. The concave arc strip 53 can be mounted on the lower mold 1 through the mounting bars 51, and the inner wall of the concave arc strip 53 is arc-shaped, which facilitates smoothing of concrete and avoids the situation of concrete scattering when smoothing concrete as much as possible.

[0036] One side of the concave arc strip 53 is fixedly connected with the installation arc strip 52, and both ends of the installation arc strip 52 are fixedly connected with sliders 56. The two installation strips 51 are provided with a slide groove on one side close to the installation arc strip 52, and the slider 56 is slidably connected to the surface of the slide groove on the installation strip 51. The slider 56 slidably connected to the surface of the slide groove on the installation strip 51 can move, thereby ensuring that the installation arc strip 52 can move, and the concave arc strip 53 can be installed on the installation strip 51 through the installation arc strip 52. Four fixing rods 55 are fixedly connected to the lower surfaces of the two installation strips 51, and eight fixing plates 54 are fixedly connected to the surface of the lower mold 1. The position of the installation strip 51 can be limited by the fixing plates 54 and the fixing rods 55, so that the installation strip 51 can be installed on the lower mold 1.

[0037] Working principle: When using the steel mold for producing post-tensioned prestressed concrete pipe piles to produce concrete pipe piles, first install the steel cage 3 into the lower mold 1, then evenly spread the concrete in the lower mold 1, and then connect the upper mold 2 and the lower mold 1, and complete the processing of the concrete pipe pile by rotating the steel mold. When connecting the lower mold 1 and the upper mold 2, first pull the pull plate 409 to drive the pull rod 408 to slide on the inner wall of the first curved plate 406, so that the pull plate 409 moves away from the first curved plate 406, and then move the connecting strip 401 close to the lower mold 1, release the pull plate 409, and under the action of the elastic force of the spring 410, the pull rod 408 moves close to the second curved plate 407 to limit the position of the connecting strip 401, and then move the upper mold 2 close to the lower mold 1, grab the handle 405, and push the push plate 403 to make the pad 404 move close to the upper mold 2 to limit the position of the upper mold 2, and then continue to move the upper mold 2 close to the lower mold 1. Close to the lower mold 1, fix the upper mold 2 and the lower mold 1. After completing the connection between the upper mold 2 and the lower mold 1, pull the pull plate 409 to move the pull rod 408 away from the second arc plate 407, release the restriction on the position of the connecting strip 401, move the rectangular plate 402, and make the connecting strip 401 away from the lower mold 1. By setting the positioning device 4, when connecting the upper mold 2 and the lower mold 1, it is convenient for the staff to adjust and limit the position of the upper mold 2, and at the same time, the docking accuracy between the upper mold 2 and the lower mold 1 can be guaranteed as much as possible, thereby improving the efficiency of the connection between the upper mold 2 and the lower mold 1.

[0038] After spreading concrete in the lower mold 1, move the installation strip 51 so that the fixing rod 55 moves close to the fixing plate 54, install the installation strip 51 on the lower mold 1, and then move the installation arc strip 52 so that the slider 56 slides on the slide groove surface on the installation strip 51, so that the concrete can be smoothed by using the concave arc strip 53. After completing the smoothing of the concrete, move the installation strip 51 so that the fixing rod 55 moves away from the fixing plate 54, and complete the disassembly of the installation strip 51. By setting the smoothing device 5, it is convenient for the staff to smooth the concrete after spreading the concrete in the lower mold 1, thereby improving the staff's efficiency in smoothing the concrete. At the same time, the inner wall of the concave arc strip 53 is set in an arc shape, which can ensure that the concrete is not spilled when smoothing the concrete.
