[0001] The utility model belongs to the technical field of cement well plate pouring, and particularly relates to a pouring mold for an annular cement well plate. Background Art
[0002] The cement well plate is made of cement concrete and sand, and is produced by placing the materials in a mold and solidifying. It is used at the edge of the wellhead of farmland machinery to facilitate the sealing of the manhole cover and the well pipe. The normally used cement well plate is of a ring structure. When it needs to be stacked for use, it can be directly stacked. There are gaps between the well plates, and it is difficult to ensure the concentric dimension. Pouring with a mold is also time-consuming and laborious, with high costs and long construction periods. Summary of the Invention
[0003] The purpose of the utility model is to provide a pouring mold for an annular cement well plate to solve the problems existing in the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a pouring mold for an annular cement well plate, which includes a base. An outer shell, an oval inner shell, and a short-round inner shell are clamped on the base. The oval inner shell and the short-round inner shell are clamped with each other to form an annular inner shell. An end cover is clamped on the top ends of the outer shell and the annular inner shell. A lifting cylinder is placed at the central position of the base. A handle is provided at the top end of the lifting cylinder. Two support rods are hinged to the oval inner shell, and the two support rods are hinged to the outer wall of the lifting cylinder. Two support rod groups are hinged to the short-round inner shell, and the two support rod groups are hinged to the outer wall of the lifting cylinder. Pouring ports and risers are opened on the end cover.
[0005] Further, the base is circular, and annular first clamping protrusions and second clamping protrusions coaxial with the base are provided on the base from the inside to the outside.
[0006] Further, there are two oval inner shells and two short-round inner shells. Both the oval inner shell and the short-round inner shell are arc-shaped. The length of the oval inner shell is greater than that of the short-round inner shell. Third clamping protrusions are provided at both ends of the oval inner shell and the short-round inner shell. The oval inner shell and the short-round inner shell are distributed at intervals, and the oval inner shell and the short-round inner shell are clamped with each other through the third clamping protrusions to form an annular inner shell as a whole.
[0007] Further, first clamping protrusions are provided at the bottom ends of the oval inner shell and the short-round inner shell. The first clamping protrusions at the bottom ends of the oval inner shell and the short-round inner shell are clamped on the first clamping protrusions on the inner circle of the base. Inner clamping platforms are provided on the outer walls at the middle positions of the oval inner shell and the short-round inner shell.
[0008] Further, the outer shell is formed into a ring by bolting two semi-circular ring-shaped shells. A second clamping protrusion is provided at the bottom end of the outer shell. The second clamping protrusion at the bottom end of the outer shell is clamped on the second clamping protrusion on the outer circle of the base. A fourth clamping protrusion is provided at the top end of the outer shell.
[0009] Further, the end cap is annular. An inner clamping platform is provided at the bottom of the inner circle of the end cap, and a fourth clamping projection is provided at the bottom of the outer circle of the end cap. The inner clamping platform at the bottom of the end cap is clamped on the inner clamping platforms of the long-round inner shell and the short-round inner shell, and the fourth clamping projection of the end cap is clamped on the fourth clamping projection of the outer shell.
[0010] Further, the strut group is composed of two struts hinged to each other, and the length of the strut group is greater than the distance between the short-round inner shell and the lifting cylinder.
[0011] Further, the outer shell, the long-round inner shell, the short-round inner shell, and the end cap enclose an annular cavity, and the shape of the cavity matches the outer contour of the cement well plate.
[0012] Further, the outer shell and the annular inner shell both have a 2° draft angle on the pouring side.
[0013] The utility model has the following beneficial effects:
[0014] 1. The outer shell and the base, the annular inner shell and the base, the end cap and the outer shell, and the end cap and the annular inner shell all adopt stepped clamping, and the side of the clamping part in contact with the cement well plate is higher than the other side. This not only ensures the assembly tightness between the structures, but also effectively prevents slurry leakage, further ensuring the pouring effect.
[0015] 2. The outer shell and the annular inner shell both have a 2° draft angle on the pouring side, which is convenient for taking out the inner shell and the outer shell.
[0016] 3. Through the cooperation of the lifting cylinder and the struts, the utility model can first completely pull the annular inner shell away from the cement blank, rather than directly lifting the inner shell. Direct lifting has a great frictional force and high operation difficulty. The operation method of the utility model can quickly remove the formwork, effectively ensure the pouring effect, is easy to operate, and has high reliability.
[0017] 4. The annular inner shell of the utility model is composed of two long-round inner shells and two short-round inner shells clamped to each other, and also adopts the stepped clamping method. This not only improves the sealing performance of the inner shell, ensures the pouring quality, but also can be disassembled in groups, with convenient operation.
[0018] 5. The outer shell of the utility model is formed into an annular shape by bolting two semi-circular ring-shaped shells, which further improves the operability, not only ensures the pouring quality, but also is very convenient to disassemble.
[0019] 6. When the utility model is used for well plate pouring and disassembly, it is convenient to operate, easy to maintain, and has a low cost. If a component is damaged, only the corresponding component needs to be replaced, and there is no need to replace all components.
[0020] 7. The base, the outer shell, the annular inner shell, the end cap, etc. of the utility model can all be formed by casting or milling, with convenient processing and high precision, ensuring the concentric dimension of the well plate.
[0021] 8. The long oval inner shell and the short oval inner shell are respectively hinged to the lifting cylinder through a strut group and a strut. This segmented structure can shrink the whole circular structure, which cannot be shrunk in a normal annular structure. However, the annular inner shell of the present utility model can achieve the shrinking effect, and the operation is very simple, thus facilitating mold release. BRIEF DESCRIPTION OF THE DRAWINGS

A pouring port 9 and a riser 10 are provided on the end cover 5.
[0032] The base 16 is circular, and an annular first clamping projection 11 and a second clamping projection 12 coaxial with the base 16 are provided on the base 16 from the inside to the outside.
[0033] The first clamping projection 11 is used to snap-connect the annular inner housing 4, and the second clamping projection 12 is used to snap-connect the housing 1.
[0034] There are two oval inner housings 2 and two short-round inner housings 3. Both the oval inner housing 2 and the short-round inner housing 3 are arc-shaped. The length of the oval inner housing 2 is greater than that of the short-round inner housing 3. Third clamping projections 13 are provided at both ends of the oval inner housing 2 and the short-round inner housing 3. The oval inner housing 2 and the short-round inner housing 3 are spaced apart, and the oval inner housing 2 and the short-round inner housing 3 are snap-connected to each other through the third clamping projections 13 to form an annular inner housing 4 as a whole. The third clamping projection 13 is used for the oval inner housing 2 and the short-round inner housing 3 to be snap-connected to each other to form a ring.
[0035] First clamping projections 11 are provided at the bottom ends of the oval inner housing 2 and the short-round inner housing 3. The first clamping projections 11 at the bottom ends of the oval inner housing 2 and the short-round inner housing 3 are snap-connected to the first clamping projections 11 on the inner ring of the base 16. Inner clamping platforms 15 are provided on the outer walls at the middle positions of the oval inner housing 2 and the short-round inner housing 3. The inner clamping platform 15 is used to snap-connect the inner ring of the end cover 5.
[0036] The housing 1 is formed by bolting two semi-circular ring-shaped shells to form a ring. A second clamping projection 12 is provided at the bottom end of the housing 1. The second clamping projection 12 at the bottom end of the housing 1 is snap-connected to the second clamping projection 12 on the outer ring of the base 16. A fourth clamping projection 14 is provided at the top end of the housing 1. The fourth clamping projection 14 is used to snap-connect the outer ring of the end cover 5.

A fourth clamping projection 14 is provided at the bottom of the outer ring of the end cover 5. The inner clamping platform 15 at the bottom of the end cover 5 is snap-connected to the inner clamping platforms 15 of the oval inner housing 2 and the short-round inner housing 3.

[0040] The outer shell 1 and the annular inner shell 4 both have a draft angle of 2° on the pouring side, which facilitates the demolding of the outer shell 1 and the annular inner shell 4.
[0041] The working principle of the present utility model is as follows:
[0042] As Figures 6-7 shown, at the beginning of the pouring operation, each component is combined to make the cavity in a closed state. At this time, the support rod 8 is in a horizontal position, and the long-round inner shell 2 and the short-round inner shell 3 are in a closed state. When pouring, first open the end cover 5, pour cement inward. After the pouring height exceeds 80%, place the end cover 5, continue pouring at the pouring port 9. When the cement emerges from the riser 10, flatten the surface, seal the pouring port 9 and the riser 10. After the cement solidifies and forms, start the mold disassembly.
[0043] At the beginning of the mold disassembly process, first remove the end cover 5, then lift the handle 7, and then lift out the lifting cylinder 6. The lifting cylinder 6 drives the support rod 8 to lift, and preferentially pulls the short-round inner shell 3 away from the cement well plate. Since the support rod group 17 connected to the long-round inner shell 2 is segmented and its length is greater than the distance between the short-round inner shell 3 and the lifting cylinder 6, after the short-round inner shell 3 is pulled, the long-round inner shell 2 will be pulled by the traction force and separated from the cement blank, so that all the inner shells can be disassembled.
[0044] In the second step of disassembly, loosen the bolts connecting the outer shell 1, separate the shells of the two closely connected outer shells 1, and disassemble the outer shell 1. Finally, after removing the cement well plate, start the pouring of the next well plate.
[0045] The embodiments described above are only descriptions of the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various variations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should all fall within the protection scope of the present utility model.
[0046] The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
