[0002] Concrete is one of the most durable man-made building materials. Besides traditional structural engineering, it's also widely used in decorative, environmental, road, and landscaping projects. Concrete products primarily utilize factory-prefabricated production methods, such as pavement bricks, decorative blocks, and decorative concrete veneers. These blocks are typically produced by placing the concrete mix into a box-shaped mold with holes for easy demolding. The mix is then compacted through vibration and tamping, initially cured, and then demolded. After curing, the finished blocks are then formed.
[0003] At present, when preparing concrete, a special molding mold needs to be customized according to its size so that it can solidify and form. However, in order to improve the structural strength, traditional molding molds are mostly one-piece molding structures. Since the sides of the concrete are tightly attached to the inner wall of the mold when solidifying, there is a large viscosity and static friction resistance between the inner walls of the one-piece mold and the concrete, which causes inconvenience when removing. Even if it is forcibly removed, the sides of the concrete are easily damaged due to viscosity and static friction resistance, resulting in an increase in the defective rate. Therefore, it is necessary to propose a demoulding device for house construction concrete. Summary of the Invention

The movement of the demoulding soft plate 21 forms a progressive peeling on the concrete surface.
[0035] Multiple buffer springs 2 are evenly distributed along the circumference of the demolding box 3. The outer side of the demolding box 3 is symmetrically fixedly connected with a horizontal plate 4. The side of the horizontal plate 4 close to the bottom plate 1 is fixedly connected with a first fixed block 5. The outer side of the first fixed block 5 is fixedly connected with a first fixed rod 6. The function of the first fixed block 5 is to connect the first fixed rod 6 and the horizontal plate 4. When the first fixed block 5 moves in the vertical direction, it will drive the horizontal plate 4 to move.
[0036] The side of the base plate 1 close to the demolding box 3 is fixedly connected to the dual-axis motor 8, the end of the output shaft of the dual-axis motor 8 is fixedly connected to the extension shaft 9, the outer side of the extension shaft 9 is fixedly connected to the traction rope 7, and the end of the traction rope 7 away from the dual-axis motor 8 is fixedly connected to the first fixed rod 6.

The inner bottom of the first placement groove 11 is fixedly connected to the telescopic motor 12, and the telescopic motor 12 is placed on the inner side of the first placement groove 11 opened in the second fixed block 10.
[0038] A first movable groove 13 is symmetrically opened at the end of the output shaft of the telescopic motor 12. A second fixed rod 14 is fixedly connected to the inner side of the telescopic motor 12. The outer side of the second fixed rod 14 is movably connected to the oscillation rod 15. The second fixed rod 14 is fixed to the inner side of the first movable groove 13 opened at the end of the output shaft of the telescopic motor 12.
[0039] A first sliding groove 16 is provided at the inner bottom of the demolding box 3, and the first sliding groove 16 and the sliding plate 17 are slidingly connected.

The outer side of the third fixed rod 19 is movably connected to the oscillation rod 15. The third fixed rod 19 is pushed by the oscillation rod 15 to push the sliding plate 17 to slide on the inner side of the first sliding groove 16.
[0040] The inner bottom of the demoulding box 3 is fixedly connected to a plurality of limiting arc plates 20 , which are evenly distributed along the circumference of the demoulding box 3 . The function of the limiting arc plates 20 is to limit the position of the demoulding soft plate 21 .
[0041] In this embodiment, the specific implementation method is that, when in use, concrete is poured into the inner side of the limiting arc plate 20, and the dual-axis motor 8 is started. The output shafts at both ends of the dual-axis motor 8 rotate intermittently. During the rotation of the output shaft of the dual-axis motor 8, the traction rope 7 is pulled. The movement of the traction rope 7 drives the first fixed rod 6, thereby driving the first fixed block 5 to move in the vertical direction. The function of the first fixed block 5 is to connect the first fixed rod 6 and the cross plate 4. When the first fixed block 5 moves in the vertical direction, it drives the cross plate 4 to move, and the movement of the cross plate 4 The movement will drive the demoulding box 3 to move in the vertical direction. By intermittently pulling the two sets of horizontal plates 4 through the two sets of traction ropes 7, the demoulding box 3 will vibrate. The vibration of the demoulding box 3 will drive the concrete on the inner side of the limiting arc plate 20 to vibrate. This vibration mode forms a dynamic force on the concrete component. Compared with the traditional demoulding method, the vibration effect of the device can effectively destroy the bonding force between the concrete and the mold. Through high-frequency and directional vibration transmission, the concrete forms a uniform micro-displacement on the inner wall of the mold, which significantly reduces the demoulding resistance. When the dual-axis motor 8 stops starting, the buffer spring 2 will return the demoulding box 3 to its original position. At the same time as the demoulding box 3 vibrates, the telescopic motor 12 will start. The telescopic motor 12 is placed on the inner side of the first placement slot 11 opened on the second fixed block 10. The output shaft of the telescopic motor 12 will extend and retract in the vertical direction. The extension and retraction of the telescopic motor 12 will drive the oscillation rod 15 to move on the outer side of the second fixed rod 14. The second fixed rod 14 is fixed on the inner side of the first movable slot 13 opened on the end of the output shaft of the telescopic motor 12. The movement of the oscillation rod 15 will push the third The fixed rod 19 and the third fixed rod 19 are pushed by the oscillation rod 15 to push the sliding plate 17 to slide on the inner side of the first sliding groove 16. The size of the sliding plate 17 is adapted to the size of the first sliding groove 16. By starting the telescopic motor 12, the two sets of oscillation rods 15 will slide back and forth along the first sliding groove 16. The oscillation rod 15 will further oscillate the inner side of the concrete inside the limiting arc plate 20. When the oscillation rod 15 slides to the lowest point, the oscillation rod 15 will coincide with the first sliding groove 16. At this time, it will not affect the demoulding of the concrete.

There are two groups of servo motors 23, and the output shaft end of the servo motor 23 is fixedly connected to the rotating shaft 24. The outer side of the rotating shaft 24 is fixedly connected to the gear 26. The rotation of the rotating shaft 24 will drive the gear 26 to rotate.
[0044] The inner bottom of the second sliding groove 22 is slidably connected to the demoulding soft plate 21 , and the demoulding soft plate 21 is in contact with the limiting arc plate 20 , so that the demoulding soft plate 21 moves outside the limiting arc plate 20 .
[0045] A rack 25 is symmetrically fixedly connected to the outer side of the demoulding soft plate 21 . The rack 25 is meshed with a gear 26 . The rotation of the gear 26 drives the rack 25 to move.

The rotation of the rotating shaft 24 drives the gear 26 to rotate. Because the gear 26 and the rack 25 are meshed, the rotation of the gear 26 drives the rack 25 to move. The end of the rack 25 away from the gear 26 is fixedly connected to the demoulding soft plate 21. The movement of the rack 25 drives the demoulding soft plate 21 to move, and the demoulding soft plate 21 will move on the outside of the limiting arc plate 20. The function of the limiting arc plate 20 is to limit the position of the demoulding soft plate 21. The demoulding soft plate 21 forms a continuous and uniform rotation trajectory along the limiting arc plate 20. The demoulding soft plate 21 ensures sufficient flexibility to fit the curved surface of the limiting arc plate 20, and forms a progressive peeling effect on the concrete surface during the rotation process, thereby realizing the demoulding of the concrete on the inner side of the demoulding soft plate 21.
