[0001] This utility model relates to the field of mold technology, and in particular to an adjustable well barrel forming mold. Background Technology

[0002] In numerous fields such as urban construction, water conservancy projects, and underground pipeline laying, manholes are widely used as an important infrastructure component in structures such as inspection wells and drainage wells. Traditional manhole molding molds are usually fixed structures, capable of manufacturing manholes of specific sizes. When a project requires manholes of different heights, the entire set of molds must be replaced. This not only increases production costs but also leads to mold inventory buildup, occupying a significant amount of storage space. Furthermore, the mold replacement process is cumbersome, consuming considerable time and manpower, reducing production efficiency. Moreover, existing molds require bolted connections for fixation during use, making installation and demolding relatively difficult and resulting in lower production efficiency. Utility Model Content

[0003] This invention proposes an adjustable well casing forming mold to solve the problem that existing molds can only manufacture well casings of a specific size.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable well shaft forming mold, comprising a first mold component, the first mold component comprising an inner mold portion and two outer mold portions, the inner mold portion being located between the two outer mold portions, and the inner walls of the two outer mold portions forming a forming cavity for casting the well shaft between the inner mold portion and the inner mold portion, two first connecting plates being fixedly connected to both sides of the circumference of one outer mold portion, and two second connecting plates being fixedly connected to both sides of the circumference of the other outer mold portion, the second connecting plates having recessed through-holes, a rod being fixedly connected to the side of the first connecting plate facing the second connecting plate, and a deformable limiting plate being fixedly connected to the side of the second connecting plate away from the first connecting plate, the limiting plate being located on the side of the through-hole, and a limiting groove matching the limiting plate being formed on the side of the rod.

[0006] Preferably, the mold further includes a second mold component, which is located above the first inner mold and includes a second inner mold and two second outer mold portions. The top of the second inner mold protrudes to form a second connecting rod, and the bottom of the second inner mold is recessed to form a connecting hole. The top of the inner mold portion protrudes to form a first connecting rod. The connecting hole matches the second connecting rod and the first connecting rod. The outer peripheral surfaces of the first main mold shell and the first secondary mold shell are fixedly connected to a first side plate. The top of the first side plate is fixedly connected to a first positioning rod. Holes matching the first positioning rod are formed on both second outer mold portions.

[0007] Preferably, the second outer mold portion includes a second mold shell, and a third side plate is fixedly connected to the outer peripheral surface of the second mold shell, and a hole matching the first positioning rod is opened on the third side plate.

[0009] Preferably, protrusions are fixedly connected to both sides of the symmetrical periphery of the first inner mold, and mold holes matching the protrusions are formed in the first secondary mold shell and the first main mold shell.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] (1) In this application, when the two outer mold parts are connected, the insert rod is inserted into the insertion hole and the limiting plate engages with the limiting groove to connect the two outer mold parts. When the two outer mold parts need to be disassembled, the limiting plate can be pulled apart from the limiting groove to demold. Therefore, the mold does not need to be fixed by bolts during use. Thus, the installation and demolding are relatively easy and the production efficiency is high.

[0012] (2) By setting a first connecting rod, a connecting hole, a first positioning rod, a second positioning rod, and a third side plate, the second connecting rod is screwed into the connecting hole to connect the required number of second inner molds.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6As shown, an adjustable well shaft forming mold includes a first mold component 1, which includes an inner mold portion and two outer mold portions. The inner mold portion is located between the two outer mold portions, and the inner walls of the two outer mold portions and the inner mold portion form a forming cavity for casting the well shaft. Two first connecting plates 19 are fixedly connected to both sides of the circumference of one outer mold portion, and two second connecting plates 112 are fixedly connected to both sides of the circumference of the other outer mold portion. A through-hole 113 is formed in the recess of the second connecting plate 112. A rod 110 is fixedly connected to the side of the first connecting plate 19 facing the second connecting plate 112. A deformable limiting plate 114 is fixedly connected to the side of the second connecting plate 112 away from the first connecting plate 19. The limiting plate 114 is located on one side of the insertion hole 113, and a limiting groove 111 matching the limiting plate 114 is opened on one side of the rod 110.

[0023] With the above technical solution, when personnel need to produce a well shaft, the inner mold part is placed between the two outer mold parts, and the insertion rod 110 on the first connecting plate 19 is inserted into the insertion hole 113 on the second connecting plate 112. The limiting plate 114 on the second connecting plate 112 is engaged with the limiting groove 111 on the insertion rod 110, so that the second connecting plate 112 and the first connecting plate 19 are connected, thereby completing the connection of the two outer mold parts. Then, concrete is poured into the forming cavity between the inner mold part and the two outer mold parts. After the concrete solidifies to form a well shaft, the limiting plate 114 is pulled to separate the limiting plate 114 from the limiting groove 111 on the insertion rod 110, thereby separating the first connecting plate 19 and the second connecting plate 112, and thus separating the two outer mold parts. Finally, the well shaft is taken out from the inner mold part, completing the production of the well shaft.

[0024] Specifically, in one embodiment, regarding the aforementioned inner mold portion, as... Figures 1-3 As shown, the inner mold part includes a first inner mold 12, and a base 11 is fixedly connected to the bottom of the first inner mold 12. The outer mold part includes a first main mold shell 15 and a first secondary mold shell 16 arranged symmetrically. A first connecting plate 19 is fixedly connected to the first secondary mold shell 16, and a second connecting plate 112 is fixedly connected to the first main mold shell 15.

[0025] In this embodiment, the first inner mold 12 is placed between the first main mold shell 15 and the first secondary mold shell 16. The first main mold shell 15 supports the second connecting plate 112, and the first secondary mold shell 16 supports the first connecting plate 19. The insertion rod 110 on the first connecting plate 19 is inserted into the insertion hole 113 on the second connecting plate 112, and the limiting plate 114 on the second connecting plate 112 engages with the limiting groove 111 on the insertion rod 110, thereby connecting the second connecting plate 112 and the first connecting plate 19. Then, the connection between the first main mold shell 15 and the first secondary mold shell 16 is completed. Then, concrete is poured into the forming cavity between the first inner mold 12 and the first main mold shell 15 and the first secondary mold shell 16. After the concrete solidifies to form a well shaft, the limiting plate 114 is pulled to separate the limiting plate 114 from the limiting groove 111 on the insert rod 110, thereby separating the first connecting plate 19 and the second connecting plate 112, and then separating the first main mold shell 15 and the first secondary mold shell 16. Finally, the well shaft is taken out from the first inner mold 12 to complete the production of the well shaft.

[0026] Furthermore, in this invention, to allow the device to adjust the length of the well shaft as needed, such as... Figures 1-6 As shown, it also includes a second mold component 2, which is located above the first inner mold 12. The second mold component 2 includes a second inner mold 21 and two second outer mold parts. The top of the second inner mold 21 protrudes outward to form a second connecting rod 22, and the bottom of the second inner mold 21 is recessed to form a connecting hole 27. The top of the inner mold part protrudes outward to form a first connecting rod 14. The connecting hole 27 matches the second connecting rod 22 and the first connecting rod 14. The outer peripheral surfaces of the first main mold shell 15 and the first secondary mold shell 16 are both fixedly connected to a first side plate 17. The top of the first side plate 17 is fixedly connected to a first positioning rod 18. Holes matching the first positioning rod 18 are formed on both second outer mold parts.

[0027] In this embodiment, after the first inner mold 12 is placed between the first main mold shell 15 and the first secondary mold shell 16, and the first main mold shell 15 and the first secondary mold shell 16 are connected, the second inner mold 21 is screwed to the second connecting rod 22 through the connecting hole 27. Then, the two second outer mold parts are placed on the first main mold shell 15 and the first secondary mold shell 16 respectively. The first main mold shell 15 and the first secondary mold shell 16 support the first side plate 17, and the first side plate 17 supports the first positioning rod 18. When the second outer mold part is placed on the first... After the main mold shell 15 and the first auxiliary mold shell 16 are attached, the first positioning rod 18 is inserted into the hole on the second outer mold part to complete the connection between the second outer mold part and the first main mold shell 15 and the first auxiliary mold shell 16. The release agent is sprayed onto the device, and then concrete is poured between the first inner mold 12, the second inner mold 21, the first main mold shell 15 and the first auxiliary mold shell 16, and the second outer mold part. After the concrete solidifies, a well shaft is formed. Then the first main mold shell 15, the first auxiliary mold shell 16, and the second outer mold part are disassembled to demold the well shaft.

[0028] Specifically, in one embodiment, regarding the aforementioned second outer mold portion, as... Figures 1-6 As shown, the second outer mold part includes a second mold shell 23, and a third side plate 26 is fixedly connected to the outer peripheral surface of the second mold shell 23.

The first side plate 17 supports the first positioning rod 18. After the second mold shell 23 is placed on the first main mold shell 15 and the first sub-mold shell 16, the second mold shell 23 supports the third side plate 26. The first positioning rod 18 is inserted into the hole on the third side plate 26, thereby completing the connection between the third side plate 26 and the first main mold shell 15 and the first sub-mold shell 16.

[0030] To ensure connection when the second mold shells 23 are stacked, as follows: Figures 3-5 As shown, a second side plate 24 is also fixedly connected to the outer peripheral surface of the second mold shell 23. The second side plate 24 is located above the third side plate 26, and a second positioning rod 25 is fixedly connected to the top of the second side plate 24. The second positioning rod 25 matches the hole on the third side plate 26.

[0031] In this embodiment, before the personnel connect the second mold shell 23 to the first main mold shell 15 and the first auxiliary mold shell 16, the second mold shell 23 is placed on another second mold shell 23, and the second mold shell 23 supports the second side plate 24 and the third side plate 26. The second side plate 24 supports the second positioning rod 25, and the second positioning rod 25 is inserted into the third side plate 26. This allows the personnel to stack and connect the required number of second mold shells 23. Then, the adjusted number of second mold shells 23 is placed on the first main mold shell 15 and the first auxiliary mold shell 16, and the first positioning rod 18 is inserted into the hole on the third side plate 26. Concrete is then injected into the device, and the device is left to solidify to form a well shaft, thus completing the well shaft production and further increasing the scope of application of the device.

[0032] And in order to create the necessary holes on the surface of the well casing during production, such as Figures 1-3 As shown, protrusions 13 are fixedly connected to both sides of the symmetrical periphery of the first inner mold 12, and mold holes 115 matching the protrusions 13 are recessed on the first secondary mold shell 16 and the first main mold shell 15.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
