Description

Technical Field

[0001] This utility model relates to the field of concrete pipe production technology, and in particular to a concrete pipe forming mold. Background Technology

[0002] Currently, reinforced concrete drainage pipes are widely used in various drainage projects. Pipe production primarily employs vertical concrete casting, gradually phasing out the traditional roller-forming technology. However, vertical concrete casting first requires assembling a welded steel cage into a pipe forming mold, followed by pouring concrete under high-frequency vibration to form the pipe. During mold assembly, due to limited space in the casting pit, a base is placed first, then the inner mold is placed on the base, the steel cage is placed outside the inner mold, and finally the outer mold is assembled. However, the narrow space in the casting pit often makes outer mold assembly difficult for production personnel. If the mold is not properly assembled, grout leakage at the bottom of the pipe can occur, severely affecting the production quality of the reinforced concrete pipe and failing to meet societal demands.

[0003] In the existing technology patent CN216465315U, a reinforced concrete pipe forming mold that is easy to lock is disclosed. By inserting the fixing plate into the fixing seat and locking it, it is easy to position and install the outer mold. Then, by activating the second telescopic mechanism, the limiting rod is driven to move towards the outer mold, so that the limiting rod passes through the fixing sleeve and extends into the fixing plate, which facilitates the fixing and limiting of the fixing plate. This can effectively enhance the stability of locking the outer mold and achieve the advantage of easy locking.

[0004] In the existing methods described above, after the concrete is poured and formed, the inner mold needs to be removed from the formed concrete pipe, and then the outer mold needs to be separated from the concrete pipe to complete the demolding operation. The removal of the inner and outer molds requires a lot of manpower and mechanical equipment, and the operation process is cumbersome and inefficient. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete pipe forming mold, which solves the problem in the prior art that it is inconvenient to demold the concrete pipe after the concrete is poured and formed, which requires a lot of manpower and mechanical equipment, and the operation process is cumbersome and inefficient.

[0006] To achieve the above objectives, this utility model employs a concrete pipe forming mold, comprising a fixed base, a mold, a fixed column, two sets of fixing components, and a demolding component. The mold is disposed above the fixed base, the fixed column is fixedly disposed above the fixed base, and both sets of fixing components are disposed above the fixed base and connected to the mold. The demolding component includes two slide rails, two sliders, a clamping unit, a bracket, positive and negative threaded rods, two sleeves, and two movable rods. Both slide rails are fixedly connected to the fixed base and are located above the fixed base. The two sliders are slidably connected to their respective slide rails. The bracket is fixedly connected to the two sliders and has a limiting groove. The positive and negative threaded rods are rotatably disposed within the limiting grooves. The two sleeves are respectively sleeved on the outside of the positive and negative threaded rods and are threadedly engaged with the positive and negative threaded rods. The clamping unit is disposed within the bracket, and both ends of each movable rod are rotatably connected to the clamping unit and the corresponding sleeve, respectively.

[0007] The clamping unit includes a fixed ring, two connecting seats, two first telescopic rods, and two clamps. The fixed ring is located inside the bracket. Both connecting seats are fixedly connected to the fixed ring and are located on the outer side wall of the fixed ring. The two ends of each movable rod are rotatably connected to the corresponding connecting seat and the sleeve, respectively. The two clamps are located inside the fixed ring. Both first telescopic rods are fixedly connected to the fixed ring, and the output end of each first telescopic rod is fixedly connected to the corresponding clamp.

[0008] The clamping unit further includes two rubber pads, which are fixedly connected to the corresponding clamps and are located on the inner sidewalls of the clamps.

[0009] The demolding assembly further includes two force-applying rods, both of which are fixedly connected to the bracket and located on the outer side wall of the bracket.

[0010] The fixing assembly includes a second telescopic rod, a limiting sleeve, and a fixing rod. The second telescopic rod is fixedly connected to the fixing seat and is located above the fixing seat. The limiting sleeve is fixedly connected to the mold and is located on the outer side wall of the mold. The fixing rod is fixedly connected to the output end of the second telescopic rod and is movably connected to the limiting sleeve.

[0011] This utility model discloses a concrete pipe forming mold. During the production of the concrete pipe, the mold is inserted into a fixed column at its bottom center. Two sets of fixing components secure the mold above a fixed base. Concrete is then poured into the mold. Once the concrete pipe is formed, workers tap the outer wall of the mold to separate the pipe from the mold. Next, a support is moved above the mold, driving the positive and negative threaded rods within the limiting groove to rotate. Since both sleeves are threadedly engaged with the positive and negative threaded rods, they move away from each other within the limiting groove. Subsequently, the two movable rods are gradually stretched. A clamping unit is fitted onto the outer wall of the mold, clamping and fixing the mold. Finally, the positive and negative threaded rods are reversed, causing the two sleeves to move relative to each other within the limiting groove. The two clamping units then separate the mold from the concrete pipe. This method facilitates demolding of the concrete pipe, reduces manpower and machinery requirements, is easy to operate, and greatly improves efficiency. Attached Figure Description

The mold 102 is disposed above the fixed base 101, and the fixed column 119 is fixedly disposed above the fixed base 101. Both sets of fixing components are disposed above the fixed base 101 and are connected to the mold 102. The demolding component includes two slide rails 103, two sliders 104, a clamping unit, a bracket 105, positive and negative threaded rods 106, two sleeves 107, and two movable rods 108. Both slide rails 103 are connected to the fixed base 102. 1. Fixed connection, both located above the fixed base 101, two sliders 104 are slidably connected to the corresponding slide rails 103, the bracket 105 is fixedly connected to the two sliders 104, the bracket 105 has a limiting groove 109, the positive and negative threaded rods 106 are rotatably disposed in the limiting groove 109, two sleeves 107 are respectively sleeved on the outside of the positive and negative threaded rods 106 and are threadedly engaged with the positive and negative threaded rods 106, the clamping unit is disposed in the bracket 105, and the two ends of each movable rod 108 are rotatably connected to the clamping unit and the corresponding sleeve 107 respectively.

[0020] In this embodiment, when making the concrete pipe, the mold 102 is inserted into the fixing post 119 through the center of its bottom. The mold 102 is fixed above the fixing base 101 using two sets of fixing components. Then, concrete raw materials are poured into the mold 102. When the concrete pipe inside the mold 102 is formed, the worker taps the outer wall of the mold 102 to separate the concrete pipe from the inside of the mold 102. Then, the bracket 105 is moved to a position above the mold 102, and the positive and negative threaded rods 106 in the limiting groove 109 are driven to rotate. Since both sleeves 107 are connected to the positive and negative threaded rods... With the threaded rod 106 engaged, the two sleeves 107 are driven to move away from each other within the limiting groove 109. Subsequently, the two movable rods 108 are driven to gradually stretch. The clamping unit is sleeved on the outer wall of the mold 102, and the mold 102 is clamped and fixed by the clamping unit. Finally, the positive and negative threaded rods 106 are controlled to reverse, and the two sleeves 107 move relative to each other within the limiting groove 109. Subsequently, the two clamping units separate the mold 102 from the concrete pipe. By adopting the above method, it is possible to easily demold the concrete pipe, reduce manpower and mechanical equipment, facilitate operation, and greatly improve efficiency.

[0025] Furthermore, the demolding assembly also includes two force-applying rods 115, both of which are fixedly connected to the bracket 105 and are located on the outer side wall of the bracket 105.

[0026] In this embodiment, by providing the force-applying rod 115 on the outside of the bracket 105, the force-applying rod 115 facilitates the movement of the bracket 105 above the fixed base 101, making it convenient to use.

[0027] Furthermore, the fixing assembly includes a second telescopic rod 116, a limiting sleeve 117, and a fixing rod 118. The second telescopic rod 116 is fixedly connected to the fixing base 101 and is located above the fixing base 101. The limiting sleeve 117 is fixedly connected to the mold 102 and is located on the outer side wall of the mold 102. The fixing rod 118 is fixedly connected to the output end of the second telescopic rod 116, and the fixing rod 118 is movably connected to the limiting sleeve 117.

[0028] In this embodiment, when fixing the mold 102 above the fixing base 101, the center of the mold 102 is inserted into the fixing post 119, and the two limiting sleeves 117 on the outside of the mold 102 correspond to the fixing rod 118 respectively. Then, the two second telescopic rods 116 above the fixing base 101 are activated respectively. The output end of each second telescopic rod 116 pushes the fixing rod 118 into the limiting sleeve 117. Then, the mold 102 is fixed above the fixing base 101.
