This impact force may exceed the bearing limit of the prefabricated part material, especially for prefabricated parts with large mass or fast speed when demoulding, the microstructure inside the prefabricated part material, such as the bonding interface between cement stone and aggregate in concrete, may first appear micro cracks. These cracks are not easy to find at the beginning, but the cracks will gradually expand with the later use, seriously affecting the bearing capacity, durability and waterproof performance of the prefabricated part, and bringing potential safety hazards and quality problems to the project.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1-2 As shown, this utility model provides a flipping demolding device for demolding preforms in a mold. The mold has flanges at both ends. The flipping demolding device includes a limiting frame 1, a support component 2, and a shock-absorbing component 3. The limiting frame 1 has two limiting grooves 10 with their openings facing each other. The flanges can be inserted into the two limiting grooves 10 one by one. The support component 2 is connected to the limiting frame 1. The shock-absorbing component 3 includes a shock-absorbing plate 31 and an elastic element 32. The shock-absorbing plate 31 is slidably connected to the support component 2, and the elastic element 32 abuts against or is connected to the side of the shock-absorbing plate 31 away from the limiting frame 1. The limiting frame 1 can flip and switch between a mold-loading state and a mold-flipping state. In the mold-loading state, the limiting frame 1 is located below the shock-absorbing component 3 and is supported by the support component 2. In the mold-flipping state, the limiting frame 1 is located above the shock-absorbing component 3 and is supported by the support component 2.

[0036] The limiting frame 1 and the support component 2 are the basic structural parts of the entire demolding device. The limiting frame 1 has two limiting grooves 10 with their openings facing each other. In the molded state, the support component 2 supports the limiting frame 1, and the flanges at both ends of the mold can be inserted into the two limiting grooves 10 one by one, ensuring that the mold is relatively fixed in the subsequent demolding process, laying a stable foundation for the entire demolding process. The shock-absorbing component 3 can improve the reliability of the demolding process. In the mold flipping state, the support component 2 supports the limiting frame 1, so that the preform will fall onto the shock-absorbing plate 31 first after being ejected from the mold. At the same time, since the shock-absorbing plate 31 is slidably connected to the support component 2, the shock-absorbing plate 31 can slide downward and compress the elastic element 32. The elastic element 32 generates elastic deformation according to the pressure it receives, and buffers the impact force of the preform through its own elasticity, thereby effectively preventing the preform from cracking and other quality defects due to excessive impact force, ensuring the stability and reliability of the demolding process, and enabling the preform to be ejected from the mold smoothly and completely.

[0037] In this embodiment, the limiting frame 1 can be switched between the mold-loading state and the mold-flipping state by manual operation.

[0038] Specifically, such as Figure 2 As shown, the limiting frame 1 includes a first frame 11 and two second frames 12. The two second frames 12 are parallel to each other and spaced apart, and are tunably connected to the first frame 11. Each second frame 12 has a limiting groove 10. Since the two second frames 12 are tunably connected to the first frame 11, when encountering molds of different widths, the distance between the two limiting grooves 10 can be changed by adjusting the position of the second frames 12. For wider molds, the two second frames 12 can be adjusted away from each other to increase the distance between the limiting grooves 10, thereby securely locking the flanges at both ends of the mold; while for narrower molds, the second frames 12 can be adjusted towards each other to reduce the distance. In this way, the device can adapt to molds of various lengths, improving the versatility of the device.

[0039] In this embodiment, a sliding track is provided on the first frame 11, and a slider is provided on the second frame 12. The slider matches the track. When it is necessary to adjust the position of the second frame 12, the second frame 12 is pushed so that the slider slides on the track, thereby realizing the position adjustment. This method is relatively convenient and quick, and at the same time, it can ensure a certain connection stability.

[0040] In other embodiments, a bolt connection combined with an elongated hole can be used. An elongated hole is provided on the first frame 11, with its length direction aligned with the direction in which the second frame 12 needs adjustment. A mounting hole is provided on the second frame 12, and the connection is achieved by passing a bolt through the mounting hole in the second frame 12 and the elongated hole in the first frame 11. When the position of the second frame 12 needs adjustment, the bolt is loosened, the second frame 12 is moved to the appropriate position along the length direction of the elongated hole, and then the bolt is tightened to achieve the position adjustment. This method provides a secure and reliable connection.

[0041] More specifically, the first frame 11 is provided with a fixing groove 110, into which the flange at one end of the mold can be inserted. When the flange at one end of the mold is inserted into the fixing groove 110, it can cooperate with the flanges in the two limiting grooves 10, so that the flanges at all three ends of the mold are limited, forming a three-point fixing effect to ensure that the mold remains stable within the limiting frame 1. When the flipping demolding device switches from the mold loading state to the mold flipping state, the mold will not undergo unnecessary displacement. At the same time, the limiting groove 10 and the fixing groove 110 can work together to limit the three flanges of the mold on the limiting frame 1, so that under the action of gravity, the limiting frame 1 can prevent the mold from falling, and the preform in the mold can be successfully separated from the mold under the action of gravity.

[0042] More specifically, the limiting frame 1 also includes a connector 13, which is telescopic. One end of the connector 13 is connected to one of the second frame edges 12, and the other end is connected to the other second frame edge 12. When the limiting frame 1 is in the mold-flipping state, the flange at one end of the mold can abut against the connector 13. When the positions of the two second frame edges 12 are adjusted, the distance between them will change accordingly. The telescopic nature of the connector 13 allows it to adjust its length according to the change in the distance between the two second frame edges 12, so that the limiting frame 1 always maintains a complete frame structure. Secondly, when the limiting frame 1 is in the mold-flipping state, the connector 13, the limiting groove 10, and the fixing groove 110 can work together to limit the four flanges of the mold on the limiting frame 1. Under the action of gravity, the limiting frame 1 can effectively prevent the mold from falling through all-round limiting. At the same time, the preform in the mold can fall off and successfully separate from the mold under the action of gravity.

[0043] In this embodiment, the connector 13 adopts a design using telescopic plates. The main body of the connector 13 is provided with a sliding telescopic plate. A slide is opened along the length direction on the main body. The main body is connected to one of the second frame 12, and the telescopic plate is connected to the other second frame 12. The telescopic plate can slide in the slide. The overall telescopicity of the connector 13 is achieved by adjusting the extension or retraction length of the telescopic plate in the slide.

[0044] Specifically, the support component 2 includes a first support member 21 and a second support member 22. Both the first support member 21 and the second support member 22 are connected to the limiting frame 1. In the mold-installation state, the limiting frame 1 is located below the shock-absorbing component 3 and is supported by the second support member 22. In the mold-turning state, the limiting frame 1 is located above the shock-absorbing component 3 and is supported by the first support member 21. The arrangement of the first support member 21 and the second support member 22 can make the support structure more stable. By assigning the support tasks in different states to different components, the position and number of support members can be designed according to the specific needs during mold installation and mold turning.

[0045] More specifically, such as Figure 1 As shown, there are two of each of the first support member 21 and the second support member 22. As key components connecting the limiting frame 1 and the shock absorption assembly 3, the increased number of the first support member 21 and the second support member 22 helps to form a more stable frame structure, enhances the rigidity of the flipping demolding device as a whole, avoids deformation or twisting of the device, and thus ensures the normal operation of the entire flipping demolding device.

[0046] In this embodiment, the end of the second frame 12 away from the first frame 11 is connected to the first support member 21, and the end of the second frame 12 close to the first frame 11 is connected to the second support member 22. The two first support members 21 and the two second support members 22 are arranged in a rectangular shape in space, and the two first support members 21 and the two second support members 22 are respectively located at the four corners of the rectangle. The two first support members 21 and the two second support members 22 cooperate with each other to form a balanced force system, so that the entire device can maintain good stability in both the vertical and horizontal directions, and can effectively prevent the device from tilting, shaking or other unstable phenomena during operation.

[0047] Specifically, the first support member 21 includes a first strut, and the second support member 22 includes a second strut. Both the first and second struts pass through the damping plate 31, which can slide along the length of the first and second struts. This through-connection method tightly integrates the damping plate 31 with the first and second support members 21 and 22, enhancing the overall integrity of the device structure. Compared to other connection methods, such as simple surface bonding or indirect connection, through-connection makes the connection between components more robust and direct. This allows the device to better maintain structural integrity when subjected to external forces such as the weight of the precast component, centrifugal force, and impact force during the flipping process, reducing the possibility of relative displacement and loosening between components. On the other hand, from an installation perspective, the through-connection method is relatively simple. During the assembly of the flipping demolding device, the operation of passing the damping plate 31 through the first and second struts is straightforward and easy for workers to assemble.

[0048] In this embodiment, the damping plate 31 is slidably connected to the first support rod and the second support rod by means of clearance fit. The damping plate 31 is provided with holes for the first support rod and the second support rod to pass through. The outer diameter of the first support rod and the second support rod is smaller than the inner diameter of the corresponding holes on the damping plate 31, so that the damping plate 31 can slide on the first support rod and the second support rod. This configuration structure is simple and can improve the assembly efficiency of the device.

[0049] In other embodiments, a guide rail and a slider can be used to achieve a sliding connection between the damping plate 31 and the first and second support rods. The first and second support rods are respectively equipped with guide rails, and the damping plate 31 is provided with a slider. The slider can slide smoothly along the guide rail, thereby enabling the damping plate 31 to slide on the first and second support rods.

[0050] Specifically, such as Figure 1 As shown, the flipping and demolding device also includes a rotating component 4, which is connected to the limiting frame 1. During the flipping operation, it is difficult to accurately find the appropriate force point to directly lift the limiting frame 1 to achieve the flipping. However, the rotating component 4 makes the flipping operation simple and direct. The operator only needs to apply a rotational force to the rotating component 4 to easily control the limiting frame 1 to flip.

[0051] More specifically, the rotating component 4 is rotatably connected to the limiting frame 1, and the first support component 21 has a first limiting block 211 protruding from the limiting frame 1. When the limiting frame 1 is in the mold-mounted state, the rotating component 4 can flip the limiting frame 1 by abutting against the first limiting block 211. The first limiting block 211 provides a clear abutment point for the rotating component 4 during rotation, making the direction of the power transmitted by the rotating component 4 to the limiting frame 1 more clear. The limiting frame 1 can flip along a stable trajectory, improving the flipping accuracy and ensuring that the demolding process can proceed according to the predetermined plan.

[0052] More specifically, the rotating component 4 is rotatably connected to the limiting frame 1, and the second support component 22 has a second limiting block 221 protruding from the limiting frame 1. When the limiting frame 1 is in the mold-flipping state, the rotating component 4 can shake the limiting frame 1 by abutting against the second limiting block 221. In the mold-flipping state, the preform may adhere to the inner wall of the mold due to material properties, mold surface conditions, etc. When the rotating component 4 rotates to the position abutting against the second limiting block 221, the rotating component 4 is pressed down further, lifting the limiting frame 1. Then the rotating component 4 is lifted, and the limiting frame 1 falls under the action of gravity due to the loss of the downward pressure. This lifting and falling process causes the limiting frame 1 to produce rapid and rhythmic position changes, i.e., vibration. This vibration can use the generated vibration to break the adhesion that may exist between the preform and the mold, loosening the preform in the mold and allowing the preform to be demolded smoothly.

[0053] In this embodiment, the rotating component 4 is a U-shaped rotating component. The rotating component 4 spans across the limiting frame 1, and the two ends of the rotating component 4 are connected to the two second frame 12 in a one-to-one correspondence. This makes the force on the limiting frame 1 more uniform during the flipping process, which can avoid instability such as tilting and shaking caused by uneven force, thereby ensuring that the preform can be successfully demolded as the limiting frame 1 flips.

[0054] Specifically, the damping plate 31 is made of a stretchable material. The damping plate 31 is indirectly connected to the limiting frame 1 through the first support member 21 and the second support member 22. This connection means that any change in the limiting frame 1 may affect the damping plate 31. When the positions of the two second frame members 12 are adjusted, the internal space dimensions of the limiting frame 1 will change. Since the damping plate 31 plays a role in adapting to changes in the device's state and buffering external forces, it needs to adapt to these dimensional changes of the limiting frame 1. The damping plate 31 itself is made of a stretchable material and can expand and contract through its stretchability to maintain a reasonable fit with the limiting frame 1 and ensure that the entire device can operate normally under different conditions.

[0055] In this embodiment, the damping plate 13 is made of rubber, which has good elasticity and stretchability, allowing it to stretch and deform under external force and return to its original shape after stretching. It should be noted that the rubber damping plate 13 is a mature technology in this field. Of course, other stretchable materials can also be used in this invention.

[0056] like Figure 1 As shown, in this embodiment, elastic elements 32 are fitted onto both the first and second support rods. On the first support rod, the elastic element 32 is sandwiched between the first limiting block 211 and the damping plate 31. On the second support rod, a support is provided, and on the second support rod, the elastic element 32 is sandwiched between the support and the damping plate 31. In this embodiment, the elastic element 32 is a spring. The first limiting block 211 and the support limit one end of the spring, preventing the spring from dislodging from the first and second support rods when subjected to pressure or tension. This ensures a smooth demolding process and that the demolding device effectively performs its damping function.

[0057] In other embodiments, the elastic element 32 can also be a rubber block, which mainly utilizes the high elasticity of rubber material to achieve the shock absorption and buffering function. When the rubber block is squeezed by external force, it will undergo deformation such as twisting and stretching, and can quickly return to its original shape after the external force disappears. In this case, the elastic element 32 does not need to be sleeved on the first support rod and the second support rod, and can be directly installed on the side of the shock-absorbing plate 31 away from the limiting frame 1. The number of elastic elements 32 can be flexibly set according to the size of the shock-absorbing plate 31.

[0058] In this embodiment, the process of using the flipping demolding device to assist in demolding the preform is as follows:

[0059] First, arrange the precast parts to be demolded in sequence, adjust the spacing between the two second frame edges 12 in the limiting frame 1 according to the mold size and fix them;

[0060] Then, hold the rotating part 4 and pull the flipping demolding device to align the two limiting grooves 10 on the limiting frame 1 with the two flanges of the mold.

[0061] Then, continue to pull the flipping demolding device toward the direction of the mold so that the flanges at both ends of the mold are inserted into the two limiting grooves 10 one by one. At this time, the flange at the other end of the mold is also inserted into the fixing groove 110.

[0062] Next, rotate the rotating part 4. When the rotating part 4 abuts against the first limiting block 211, it continues to rotate. The first limiting block 211 drives the mold to rotate 180° with the second supporting part 22 as the fulcrum.

[0063] Next, rotate the rotating part 4 in the opposite direction until the rotating part 4 abuts against the second limit block 221, press down the rotating part 4, and lift the mold with the first support part 21 as the fulcrum. Lift and shake several times to make the preform fall out of the mold.

[0064] Finally, the precast component that fell onto the damping plate 31 was removed.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
