[0040] In the embodiment, the mould for cement product production includes inner mould and outer mould, the inner mould is located in the center of the mould, and the forming space is formed between the inner mould and the outer mould. Annular main body 100 is located between the inner mould and the outer mould, and is used to form a through hole on the cement product. When pouring cement between the inner mould and the outer mould, annular main body 100 can prevent cement from passing through, so as to form a through hole at annular main body 100.

[0041] The annular body 100 has a first gap 101, and the annular body 100 can be deformed through the first gap 101. When the annular body 100 needs to be taken out after the cement product is poured, only the two ends of the first gap 101 need to be moved close to each other to reduce the diameter of the annular body 100, so that the annular body 100 can be taken out from the through hole.

[0042] The top block 200 can move relative to the annular body 100 to adjust the size of the first gap 101. The top block 200 deforms the annular body 100 by abutting against the two sides of the first gap 101. The top block 200 not only can open and loosen the first gap 101, but also can block the cement from entering the inside of the annular body 100.

[0043] Further, the top block 200 has two guide inclined surfaces 210, which are away from each other along the direction close to the axis of the annular body 100, and abut against the two sides of the first gap 101, respectively.

The guide inclined surfaces 210 can gradually deform the annular body 100 along with the movement of the top block 200, so that the top block 200 can more easily push the two sides of the first gap 101 away from each other.

[0045] Further, the sleeve 300 is arranged on the inner wall of the annular body 100 away from the first gap 101 at one end and faces the first gap 101 at the other end, and the sleeve 300 passes through the axis of the annular body 100.

[0046] In this embodiment, the moving rod 400 serves as a guide device of the top block 200 to ensure that the top block 200 can move along a predetermined direction. The sleeve 300 provides a guide channel for the moving rod 400 to ensure that the moving rod 400 can move smoothly. The sleeve 300 can also serve as a fulcrum to fix the position of the top block 200 and keep the top block 200 stable. By adjusting the position of the moving rod 400, the size of the first gap 101 can be flexibly controlled.

[0047] Further, the moving rod 400 has an external thread, and the device further comprises a nut 500 arranged on the sleeve 300 in a rotatable manner, the nut 500 is threadedly connected with the moving rod 400, and the moving rod 400 moves relative to the sleeve 300 after the nut 500 is rotated.

[0048] In the embodiment, the position of the moving rod 400 is adjusted more conveniently through the threaded connection of the nut 500 and the moving rod 400, and the moving rod 400 is moved through the rotation of the nut 500, so that the labor can be saved.

[0049] Further, the device further comprises an annular ring 600 arranged on the inner wall of the annular body 100, the annular ring 600 has a second gap 601, and the two ends of the second gap 601 are respectively in abutment with the two guide inclined surfaces 210.

[0050] In the embodiment, the annular ring 600 is arranged on the inner wall of the annular body 100, which not only plays a supporting role and improves the strength of the annular body 100, but also makes the two guide inclined surfaces 210 of the top block 200 abut with the two sides of the second gap 601 when the top block 200 is completely separated from the gap, so that the two sides of the first gap 101 can be separated again when the top block 200 moves towards the first gap 101.

[0051] Further, the two ends of the annular body 100 are sealingly connected with the inner mold and the outer mold respectively.

[0052] In the embodiment, the two ends of the annular body 100 are sealingly connected with the inner mold and the outer mold respectively, so that the cement cannot pass through between the annular body 100 and the inner mold and the outer mold to enter the inside of the annular body 100, and the two ends of the annular body 100 can be in a shape that can be attached to the inner mold and the outer mold.

[0053] Further, the device further comprises a first baffle 700, one end of the first baffle 700 is hingedly arranged at one end of the first gap 101, the hinging axis of the first baffle 700 and the first gap 101 is parallel to the axis of the annular body 100; a second baffle 800, one end of the second baffle 800 is hingedly arranged at the other end of the first gap 101, the other end of the second baffle 800 is hingedly arranged at the end of the first baffle 700 away from the hinging axis of the first baffle 700, the hinging axes of the two ends of the second baffle 800 are parallel to the axis of the annular body 100, the first baffle 700 and the second baffle 800 are used for blocking the cement from entering the annular body 100; and a connecting rod 900, one end of the connecting rod 900 is arranged on the top block 200, and the other end of the connecting rod 900 is hingedly arranged at the hinging position of the first baffle 700 and the second baffle 800, the hinging axis of the connecting rod 900 is parallel to the axis of the annular body 100.

[0054] In the embodiment, the first baffle 700 and the second baffle 800 are hingedly arranged at one end close to each other, and the other end of the first baffle 700 and the second baffle 800 are hingedly arranged on both sides of the first gap 101 respectively. One end of the connecting rod 900 is arranged on the top block 200, and the other end is hingedly arranged at the hinge of the first baffle 700 and the second baffle 800. When the top block 200 moves away from the axis of the annular body 100, the top block 200 pulls the first baffle 700 and the second baffle 800 close to the axis of the annular body 100 through the connecting rod 900, and the other end of the first baffle 700 and the second baffle 800 rotates relative to the two ends of the first gap 101, and the two sides of the first gap 101 are pulled close to each other. The first baffle 700 and the second baffle 800 not only can pull or push the two sides of the first gap 101 to make the first gap 101 deform, but also can further block the cement from entering the inside of the annular body 100.

[0055] Further, the other end of the first baffle 700 and the second baffle 800 away from the axis of the annular body 100 is a circular arc surface.

[0056] In the embodiment, when the top block 200 moves away from the axis of the annular body 100, the top block 200 pushes the first baffle 700 and the second baffle 800 away from the axis of the annular body 100 through the connecting rod 900, and the other end of the first baffle 700 and the second baffle 800 rotates relative to the two sides of the first gap 101, and the other end of the first baffle 700 and the second baffle 800 pushes the two sides of the first gap 101 away from each other. The other end of the first baffle 700 and the second baffle 800 away from the axis of the annular body 100 is a circular arc surface, which can make the first baffle 700 and the second baffle 800 and the outer wall of the annular body 100 form a complete annular shape, which is beneficial to the formation of the through hole.
