Description

Technical Field

[0001] The utility model belongs to the technical field of cement culvert production, in particular to a cement culvert production mold. Background Art

[0002] A culvert refers to a pipe buried below the ground, cast with reinforced concrete, commonly known as a cement pipe. Small culverts are also made of metal materials. They are used as water diversion pipes under the entire cofferdam dam. In general, they are used as water transmission pipes. Cement pipes are mostly used as culverts for water supply and drainage pipes in most cities in my country.

[0003] When making a culvert, first you need to place a steel cage in a mold, and then deliver the stirred cement material into the mold. Then use a vibration device to make the material in the mold combine more tightly. After the material is filled, the mold is driven up by a lifting device so that the product can be demolded smoothly. When placing the steel cage, the steel cage is prone to offset, causing the steel cage to offset in the cement wall of the culvert, affecting the service life of the culvert. For this reason, it is necessary to design a cement culvert manufacturing mold to solve the above problem. Utility Model Content

[0021] Hereinafter, an embodiment of a cement culvert manufacturing mold of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-3 A cement culvert production mold according to an embodiment of the utility model is shown, which includes an outer mold 1, a steel cage body 2 and an inner mold 3: the inner mold 3 is placed in the inner cavity of the outer mold 1, the steel cage body 2 is placed in the inner cavity surrounded by the outer mold 1 and the inner mold 3, clamping blocks 4 are welded around the top of the surface of the inner mold 3, and a clamping groove 5 used in conjunction with the clamping block 4 is provided on the top of the outer mold 1. Through the coordinated use of the clamping block 4 and the clamping groove 5, when the inner mold 3 is placed, the inner mold 3 can be quickly placed in the center of the outer mold 1, thereby improving the efficiency of cement culvert production, and the left and right sides of the top of the inner mold 3 are installed with hanging rings 6, and the left and right sides of the surface of the outer mold 1 are installed with side hanging rings 7. The front, back, left and right sides of the surface of the inner mold 3 are slidably connected with push plates 8, and a connecting rod 9 is welded on the side of the push plate 8 close to the inner mold 3, and a sliding column 10 is welded on the top of the opposite side of the connecting rod 9. The inner cavity of the inner mold 3 is rotatably connected with a four-pointed star-shaped rotating disk 12 through a rotating shaft 11, and the rotating shaft 11 is welded on At the top of the four-pointed star-shaped rotating disk 12, the rotating shaft 11 is rotatably connected to the inner cavity of the inner mold 3 through a torsion spring. The front, back, left and right ends of the four-pointed star-shaped rotating disk 12 are all provided with movable grooves 13 used in conjunction with the sliding column 10.

The inner cavity of the inner mold 3 is fixedly installed with four guide rails 15, and the storage cavity 14 slides in the inner cavity of the guide rails 15. A ratchet 16 is welded on the surface of the upper end of the rotating shaft 11, and the ratchet 16 rotates at the top of the inner mold 3. The top of the inner mold 3 is rotatably connected to a pawl 17 used in conjunction with the ratchet 16 through a torsion spring. Through the coordinated use of the ratchet 16 and the pawl 17, the rotation of the rotating shaft 11 is further locked, thereby avoiding the rotation of the rotating shaft 11 when the vibration device is used to tightly combine the cement material, thereby causing the cement material to enter the inner cavity of the storage cavity 14, affecting the next use. The top of the rotating shaft 11 extends to the outside of the inner mold 3 and is fixedly connected with a flower-shaped rotating cap 18.

[0023] Working principle: When the utility model is used, the user places the steel cage body 2 in the inner cavity of the outer mold 1, and then aligns the clamping block 4 with the inner cavity of the clamping slot 5, so as to place the inner mold 3 in the inner cavity of the outer mold 1, and drives the rotating shaft 11 and the four-pointed star-shaped rotating disk 12 to rotate by rotating the flower-shaped rotating cap 18, and compresses the torsion spring, thereby driving the sliding column 10 to slide in the inner cavity of the movable groove 13, and then pushes the connecting rod 9 to slide in the inner cavity of the guide rail 15, and then drives the four push plates 8 to slide back to back, so that the four push plates 8 synchronously push the steel cage body 2, so that the steel cage body 2 is on the same vertical axis as the outer mold 1 and the inner mold 3, and the steel cage body 2 is centered, and then the flower-shaped rotating cap 18 is released to use the resilience of the torsion spring to drive the push plate 8 to be stored in the inner cavity of the storage cavity 14, and when pouring cement material into the inner cavity of the outer mold 1 and the inner mold 3, the steel cage body 2 is prevented from being offset, thereby improving the firmness of the cement culvert.

[0024] In summary, the cement culvert manufacturing mold drives the rotating shaft 11 and the four-pointed star-shaped rotating disk 12 to rotate by rotating the flower-shaped rotating cap 18, thereby driving the four connecting rods 9 to slide back to back, and then driving the four push plates 8 to synchronously push the steel cage body 2, so that the steel cage body 2 and the outer mold 1 and the inner mold 3 are on the same vertical axis, thereby avoiding the deviation of the steel cage body 2 and improving the firmness of the cement culvert.
