[0045] Reference Figures 1-5 This is the first embodiment of the present invention, which proposes a mold for easy separation of cement products and for making cement pipes. It includes: a molding outer shell 1 and a molding inner shell 2. The molding inner shell 2 is located inside the molding outer shell 1, and the molding outer shell 1 and the molding inner shell 2 form a molding space 4 for holding cement. The molding inner shell 2 includes: a first movable member 5 that is arc-shaped; a second movable member 6 that is arc-shaped. The second movable member 6 and the first movable member 5 form a ring, and the first movable member 5 and the second movable member 6 are located inside the molding outer shell 1. The second movable member 6 is formed by sequentially hinged several arc-shaped plates.

[0046] In this embodiment, during use, the inner molding shell 2 is first placed into the outer molding shell 1 to ensure the formation of the molding space 4. After the cement is poured into the molding space 4 and solidifies, the second movable part 6 is loosened, allowing the inner molding shell 2 to be easily separated. The annular structure formed by the first movable part 5 and the second movable part 6 effectively supports the cement within the molding space 4, ensuring the shape stability of the cement during the curing process and improving molding efficiency. The design of the first movable part 5 and the second movable part 6 allows for better control of the cement distribution during the molding process, ensuring high quality of the molded cement product. The design of the first movable part 5 and the second movable part 6 also makes it easier to remove the molded cement product from the molding space 4, simplifying the demolding process.

[0047] Furthermore, the first movable member 5 and the second movable member 6 are hinged at one end and abutted at the other end, and also include: a limiting seat 7 disposed on the first movable member 5, the limiting seat 7 having a through hole 8; a limiting block 9 disposed on the second movable member 6, the limiting block 9 having a limiting groove 10; and a limiting rod 11 detachably disposed on the limiting seat 7. After the first movable member 5 and the second movable member 6 form a ring, the limiting rod 11 passes through the through hole 8 and the limiting groove 10, and the limiting rod 11 is used to fix the limiting block 9.

[0048] In this embodiment, the limiting seat 7 and the limiting groove 10 need to be installed together during pouring to ensure the molding of the inner shell 2, providing sufficient support for the cement during pouring. The design of the limiting rod 11 ensures the stability of the annular structure composed of the first movable part 5 and the second movable part 6 during the molding process, improving the molding quality. The detachable design of the limiting rod 11 makes the demolding process simpler and faster, reducing the difficulty of demolding.

[0049] Reference Figures 3-5 In Embodiment 2 of this utility model, the first movable member 5 and the second movable member 6 have the same structure.

[0050] As another embodiment of this utility model, the difference between this embodiment and embodiment 1 is only that the structure of the first movable part 5 and the second movable part 6 is the same in this embodiment. With the two identical structures, there is more movable area when in use, which makes it easier to demold the cement pipe and also reduces the area of ​​adhesion.

[0051] Furthermore, it also includes: the two ends of the connector 12 are hinged to the two ends of the first movable member 5 and the second movable member 6 which are diagonally arranged; the drive shaft 13 is rotatably arranged on the connector 12; there are several rotating seats 15, which are arranged on the drive shaft 13; there are two sets of connecting rods 14, one set of connecting rods 14 is hinged to the other ends of the rotating seat 15 and the second movable member 6 respectively, and the other set of connecting rods 14 is hinged to the other ends of the rotating seat 15 and the first movable member 5 respectively. When the drive shaft 13 rotates, the rotating seat 15 drives the connecting rods 14 to move.

[0052] In this embodiment, a connecting structure such as a connector 12 is added based on embodiment 2. This not only better ensures the molding strength of the device, but also drives the rotating seat 15 to rotate through the rotation of the drive shaft 13, thus making the rotating seat 15 rotate more smoothly. In summary, the design of the drive shaft 13 and connecting rod 14 not only improves molding stability and simplifies the demolding process, but also enhances the flexibility and service life of the equipment, positively impacting the user experience and maintenance convenience.

[0053] Furthermore, one end of the first movable member 5 and one end of the second movable member 6 both have through holes 8, and the device also includes a rotating shaft 16 disposed on the connecting member 12, with the rotating shaft 16 passing through the through hole 8.

[0054] In this embodiment, the rotating shaft 16 passes through one end of the first movable member 5 or the second movable member 6. The rotating shaft 16 is located on the connecting member 12. The first movable member 5 or the second movable member 6 connected by the rotating shaft 16 will be relatively fixed by the rotating shaft 16, so that it can only rotate along the rotating shaft 16. When the device is in use, the rotating shaft 13 can rotate the first movable member 5 and the second movable member 6 to complete the demolding of the inner shell 2, which improves the demolding efficiency and also ensures the quality of cement pipe molding.

[0055] Furthermore, a support plate 17 is disposed within the forming space 4, and the support plate 17 is used to support cement.

[0056] In this embodiment, the support plate 17 is used to support the cement. The design of the support plate 17 ensures the uniform distribution of cement during the molding process, improving the molding quality. The support plate 17 provides a uniform support surface for the cement, ensuring structural stability during the molding process. The design of the support plate 17 reduces the risk of deformation and breakage of cement products during the molding process, improving the safety of use.

[0057] Furthermore, the rotation drive 18 is disposed on the connector 12, and the rotation drive 18 is used to drive the drive shaft 13 to rotate.

[0058] In this embodiment, the design of the rotation drive component 18 allows the operator to control the rotation of the drive shaft 13 with simple movements, thereby controlling the opening and closing of the first movable component 5 and the second movable component 6, simplifying the operation process and improving the convenience of operation. By rotating the drive shaft 13 through the rotation drive component 18, the first movable component 5 and the second movable component 6 can be quickly and synchronously separated, simplifying the demolding process and reducing the difficulty of demolding.

[0059] Furthermore, the first body 19 has a plurality of mounting portions 20; the second body 21 is detachably mounted on the first body 19, and the second body 21 also has a plurality of mounting portions 20; mounting bolts 22 are mounted on the mounting portions 20, and the mounting bolts 22 are used to connect different mounting portions 20.

[0060] In this embodiment, the detachable design of the first body 19 and the second body 21 makes the separation of the molded outer shell 1 faster. The support base 23 is located below the molded outer shell 1 and the molded inner shell 2.

[0061] In this embodiment, the design of the support base 23 provides stable support for the outer shell 1 and the inner shell 2, improving the overall stability of the mold and reducing shaking during the molding process. The design of the support base 23 also makes it easier to remove the molded cement product from the mold, simplifying the demolding process.

[0062] Furthermore, there are several reinforcing plates 24, which are disposed on the side of the molded outer shell 1 and the molded inner shell 2 that are not in the molding space 4. The reinforcing plates 24 are used to enhance the load-bearing capacity of the molded outer shell 1 and the molded inner shell 2.

[0063] In this embodiment, the design of the reinforcing plate 24 enhances the load-bearing capacity of the outer molding shell 1 and the inner molding shell 2, ensuring the structural integrity of the mold under heavy loads. The reinforcing plate 24 increases the overall structural strength of the mold, ensuring structural stability during the molding process and reducing the risk of mold deformation. By enhancing the load-bearing capacity of the mold, the shape stability and dimensional accuracy of the cement products during the molding process are ensured.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
