Description

Technical Field

[0001] This utility model relates to molds for prestressed steel cylinder concrete pipes, and more particularly to molds that can simultaneously meet the processing requirements of single-rubber ring pipes and double-rubber ring pipes. Background Technology

[0002] In the current concrete pipe casting process, pipe manufacturers often use a single mold to produce one type of pipe: a mold for single-ring pipes and a mold for single-ring pipes. However, customers may require different types of pipes when purchasing. In this case, the pipe manufacturer must purchase two types of molds, which undoubtedly increases production costs. The differences between the two types of pipe joints are mainly in the following two aspects: first, the number of rubber rings at the joint is different, resulting in different depths of the sockets at both ends; second, the pipe lengths are also different.

[0003] Therefore, based on the above situation, the applicant improved the original mold and produced a mold that simultaneously conforms to two types of pipes (i.e., single-ring pipe and double-ring pipe). Summary of the Invention

[0004] To address the above problems, this utility model provides a pressure pipe mold that is simple and convenient to operate and can produce both single and double rubber ring pipes.

[0005] The technical solution of this utility model is: a pressure pipe mold for single and double rubber ring pipes, including an outer mold and an inner mold. The bottom ends of the outer mold and the inner mold are provided with adjustable bottom molds with socket rings. The adjustable socket depth bottom mold includes a bottom mold body and a ring depth adjustment ring sleeved on the bottom mold body; the height of the ring depth adjustment ring is 0-150mm. The surface of the top of the outer mold is provided with an overflow outlet one and an overflow outlet two, the height of the overflow outlet one is higher than the height of the overflow outlet two; the overflow outlet two is provided with an overflow outlet opening and closing device.

[0006] Furthermore, the outer surface of the bottom mold body is provided with an outer cylindrical surface, an outer mold mating circle, and a socket ring mating circle from the outside to the inside; and the top opening of the inner surface of the bottom mold body is provided with an inner mold mating circle. The outer surface of the bottom mold body is provided with a first step surface and a second step surface from bottom to top, and the inner surface of the bottom mold body is provided with a third step surface; The first stepped surface is used to receive the bottom opening of the outer mold. The second stepped surface is used to receive the ring depth adjustment ring or the bottom of the socket ring. The third step surface is used to receive the bottom opening of the inner mold.

[0007] Furthermore, the overflow opening and closing device includes a cover plate, a fixing rod, a pressure plate, and bolts. One end of the cover plate is connected to the surface of the outer mold via a rotating pin. The pressure plate is movably disposed on the top surface of the cover plate via the bolts. The fixing rod is shaped like a "7" and its bottom end is fixedly connected to the surface of the outer mold.

[0008] Furthermore, the bottom surface of the cover plate is also provided with a matching rubber pressure plate.

[0009] Furthermore, a steel cylinder is provided between the inner wall of the outer mold and the outer wall of the inner mold.

[0010] Furthermore, a socket ring is provided at the bottom end of the steel cylinder.

[0011] Furthermore, the top of the steel cylinder is provided with a socket ring.

[0012] This invention first changes the traditional form of the bottom mold in the prior art by adding an adjustable ring depth to the traditional bottom mold, making the bottom mold in this case an adjustable socket ring depth bottom mold. This allows the formed socket portion to achieve different socket depths. Secondly, to accommodate the length differences of different types of pipes, two overflow outlet structures are opened at the top of the outer mold. The top edge height of the concrete portion at the spigot is determined by the different overflow outlet heights.

[0013] This invention enables the production of both single-ring and double-ring tubes on the same mold, reducing mold investment costs and effectively lowering production costs. Attached Figure Description

Detailed Implementation

[0016] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0017] The following is in conjunction with the instruction manual appendix. Figure 1-11 The present invention will be further described below.

[0018] A pressure pipe mold shared by single and double rubber ring pipes, including an outer mold 3 and an inner mold 4. The bottom ends of the outer mold 3 and the inner mold 4 are provided with a bottom mold 1 with adjustable socket depth, which is used to close the bottom opening of the annular cavity formed by the outer mold 3 and the inner mold 4. The top ends of the outer mold 3 and the inner mold 4 are also provided with a top mold 2, which is used to close the top opening of the annular cavity formed by the outer mold 3 and the inner mold 4.

[0019] The adjustable socket depth bottom mold 1 includes a bottom mold body 11 and a ring depth adjustment ring 12 sleeved on the bottom mold body 11; the height of the ring depth adjustment ring 12 is 0-150mm. For different specifications, the height of the ring depth adjustment ring 12 can be designed to be 0 (i.e., not installed), 25, 50, 75, 100, 120, 150mm, etc.

[0020] The top surface of the outer mold 3 is provided with overflow outlet 1 31 and overflow outlet 2 32, the height of overflow outlet 1 31 is higher than the height of overflow outlet 2 32; overflow outlet 2 32 is provided with overflow outlet opening and closing device 8.

[0021] like Figure 7As shown, the outer cylindrical surface, the outer mold mating circle 112 and the socket ring mating circle 113 are provided on the outer surface of the bottom mold body 11 from the outside to the inside, and the inner mold mating circle 114 is provided on the top opening of the inner surface of the bottom mold body 11.

[0022] The outer surface of the bottom mold body 11 is provided with a first step surface 1111 and a second step surface 1112 from bottom to top, and the inner surface of the bottom mold body 11 is provided with a third step surface 1113.

[0023] The first step surface 1111 is used to receive the bottom opening of the outer mold 3.

[0024] The second step surface 1112 is used to receive the ring depth adjustment ring 12 or the bottom of the socket ring. The socket depth can be changed by adjusting the ring depth adjustment ring 12.

[0025] The third step surface 1113 is used to receive the bottom opening of the inner mold 4.

[0026] Furthermore, the overflow opening and closing device 8 includes a cover plate 81, a fixing rod 82, a pressure plate 83, and bolts 84. One end of the cover plate 81 is connected to the surface of the outer mold 3 via a rotating pin. The pressure plate 83 is movably mounted on the top surface of the cover plate 81 via bolts 84. The fixing rod 82 is shaped like a "7", and its bottom end is fixedly connected to the surface of the outer mold. When it is necessary to close the overflow opening and closing device 8, the cover plate 81 is flipped over, and the pressure plate 83 is rotated to lock under the fixing rod 82, thus completing the closure and fixation of the cover plate 81.

[0027] During pipe manufacturing, the number of rubber rings at the pipe joints can result in different depths of the sockets at both ends. like Figure 1-3 As shown in Figures 10 and 11, when pouring the double rubber ring pipe, adjust the ring depth adjustment ring 12 on the second step surface 1112 so that the overflow outlet 2 32 is in the open and closed state, and the double rubber ring pipe can be poured. When the concrete is poured to the minimum limit of the overflow outlet 2 32, the excess concrete overflows from the overflow outlet 1 31 and the overflow outlet 2 32, achieving the appropriate length of the double rubber ring pipe and the depth of the socket. like Figure 4-6 As shown in Figures 8 and 9, when pouring the single rubber ring pipe, the ring depth adjustment ring 12 on the second step surface 1112 is adjusted, and the overflow opening and closing device 8 at the overflow outlet 2 8 is closed, then the single rubber ring pipe can be poured. When the concrete is poured to the minimum limit of the overflow outlet 1 31, the excess concrete overflows from the overflow outlet 1 31, thereby changing the adaptable length of the single rubber ring pipe and the depth of the socket.

[0028] Furthermore, a matching rubber pressure plate 86 is provided on the bottom surface of the cover plate 81. This increases the airtightness of the cover plate 81 and prevents leakage during concrete pouring.

[0029] Furthermore, a steel cylinder 7 is provided between the inner wall of the outer mold 3 and the outer wall of the inner mold 4. Before being placed between the outer mold 3 and the inner mold 4, the steel cylinder 7 is wrapped with prestressed steel wire to enhance the overall compressive strength and improve the structural stability.

[0030] Furthermore, a socket ring 5 is provided at the bottom end of the steel cylinder 7.

[0031] Furthermore, a socket ring 6 is provided at the top of the steel cylinder 7. This invention addresses the issue of different socket depths during the casting of single-ring and double-ring pipes through the interaction between the adjustable socket ring bottom mold 1 and the overflow opening / closing device 8.
