Abstract

The present invention relates to the technical field of molds for wall panel production, and discloses a mold assembly for prefabricated building wall panels and its use method, including a base. A placement plate is fixedly connected to the top of the base, and a placement groove is opened at the top of the placement plate. Before use, concrete is poured onto the top of the wooden board. Restricted by the shrinkage component and the baffle, the concrete forms a prototype of a wall panel. After the concrete is cooled and solidified, the power supply of the electric telescopic rod is turned on. At this time, the electric telescopic rod drives the fixed plate and the push plate to move horizontally, so that the inclined surface contacts multiple rollers, forcing the rollers to drive the sliding square rod to move horizontally. The horizontal movement of the sliding square rod will drive the piston plate to move outward along the inner wall of the hydraulic tank. As the piston plate moves, the piston plate will drive the push rod to move outward synchronously through the first spring. The movement of the push rod will force the shrinkage component to move outward synchronously, reducing the contact area between the wall surface and the equipment, and avoiding the large contact area from affecting the demolding efficiency of the equipment.

Description

Technical Field

[0001] The present invention relates to the technical field of die equipment for wall panel production, and specifically relates to a die assembly for prefabricated building wall panels and a using method thereof. Background Technique

[0002] When prefabricated building wall panels are produced, first determine the size of the die, then install and fix the steel bar skeleton in the die to enhance the strength and stability of the wall panel. After ensuring that the position and quantity of the steel bars are accurate, install the embedded parts according to the design requirements, and the position and fixing method need to be precisely controlled. After completion, pour the concrete into the die to fill the entire space of the wall panel. After the concrete is poured, after a certain curing time, ensure the strength and stability of the concrete, and finally take it out of the die to complete the production of the wall panel.

[0003] Among them, after the concrete sets, it will produce an adhesion effect on the surrounding area, resulting in adhesion between the wall panel and the inner wall of the die during demoulding, reducing the demoulding efficiency of the equipment. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a die assembly for prefabricated building wall panels, including a base, a placement plate fixedly connected to the top of the base, a placement groove opened on the top of the placement plate, a wooden board placed on the inner wall of the placement groove, a baffle fixedly connected to the top of the placement plate, six sliding grooves opened on the side wall of the placement plate, and a discharge port opened on the top of the placement plate;

[0005] A power mechanism, the power mechanism includes an electric telescopic rod fixedly connected to the side wall of the base, a fixing plate fixedly connected to the end of the electric telescopic rod away from the base, a pushing plate fixedly connected to the side wall of the fixing plate, and an inclined surface opened at the end of the pushing plate away from the fixing plate;

[0006] Limit mechanism. The limit mechanism includes sliders slidably connected to the inner walls of six chutes. A connecting frame is fixedly connected to the bottoms of the six sliders. A mounting plate is fixedly connected to the tops of the sliders. A plurality of fixed boxes are fixedly connected to the tops of the mounting plates. A sliding square rod is slidably connected to the inner wall of the through hole of the fixed box. A roller is fixedly connected to the top of the sliding square rod. A piston plate is fixedly connected to the end of the sliding square rod away from the roller. A first spring is fixedly connected to the side wall of the piston plate. The end of the first spring away from the piston plate is fixedly connected to a hydraulic tank. A push rod is fixedly connected to the side wall of the hydraulic tank. A contraction assembly is slidably connected to the inner wall of the fixed box. A limiting assembly is fixedly connected to the inner wall of the fixed box. To address the problem of difficult demolding, a limit mechanism and a contraction assembly are provided inside the device. Before use, install the base at the required position, place the wooden board inside the placement groove, and ensure that the sliding baffle and the chute are in an overlapping state. The electric telescopic rod is in an extended state. At this time, pour the concrete onto the top of the wooden board. The concrete is restricted by the contraction assembly and the baffle to form a prototype of a wall panel. The side wall of the wall panel contacts the side wall of the contraction assembly. After the concrete cools and solidifies, connect the power supply of the electric telescopic rod. At this time, the electric telescopic rod drives the fixed plate and the push plate to move horizontally, so that the inclined surface contacts multiple rollers, forcing the rollers to drive the sliding square rod to move horizontally. The horizontal movement of the sliding square rod will drive the piston plate to move outward along the inner wall of the hydraulic tank. As the piston plate moves, the piston plate will drive the push rod to move outward synchronously through the first spring. The movement of the push rod will force the contraction assembly to move outward synchronously, forcing the side wall of the contraction assembly to separate from the side wall of the wall panel. Through the application of the above components, the contact area between the wall surface and the device is reduced, avoiding the large contact area from affecting the demolding efficiency of the device.

[0007] Preferably, the contraction assembly includes a first sliding square ring slidably connected to the inner wall of the fixed box. A second sliding square ring is slidably connected to the inner wall of the first sliding square ring. A third sliding square ring is slidably connected to the inner wall of the second sliding square ring.

[0008] Preferably, the contraction assembly further includes a fourth sliding square ring slidably connected to the inner wall of the third sliding square ring. The inner wall of the fourth sliding square ring is slidably connected to the outer wall of the push rod. A miscellaneous material opening is provided at the bottom of the fixed box.

[0009] Preferably, the contraction assembly further includes a third spring fixedly connected to the side wall of the sliding square rod. The end of the third spring away from the sliding square rod is fixedly connected to the side wall of the fixed box. The side wall of the piston plate is slidably connected to the inner wall of the hydraulic tank. Utilizing the characteristic that the push rod drives the contraction assembly to move, the contraction assembly is divided into multiple sliding components. Among them, when the push rod moves outward, it will drive the outer fourth sliding square ring to move synchronously. The horizontal movement of the fourth sliding square ring will drive the outer third sliding square ring, the third sliding square ring drives the second sliding square ring, and the second sliding square ring drives the first sliding square ring to slide along the inner wall of the fixed box, so that the contraction assembly moves from Figure 7The state of G changes to the state of F. Through the application of the above components, when the contraction component moves away from the wall panel, the contact area with the wall surface will gradually decrease, avoiding the phenomenon that the area of single peeling is too large, resulting in partial peeling of the side wall of the wall panel and unevenness of the side wall of the wall panel.

[0010] Preferably, the limiting component includes a slide rail fixedly connected to the inner wall of the fixed box. A bevel block is slidably connected to the inner wall of the slide rail. A second spring is fixedly connected to the side wall of the bevel block. By using the characteristic that the above-mentioned sliding square rod drives the hydraulic tank to move horizontally, a limiting component is arranged inside the equipment. When the equipment has not started demoulding, the sliding square rod is pulled by the third spring and the first spring, forcing the piston plate to move inward along the inner wall of the hydraulic tank. During this process, the liquid inside the hydraulic tank is pressurized and enters the hydraulic telescopic rod, forcing the hydraulic telescopic rod to extend. When the extension is completed, the sliding square rod will drive the hydraulic tank towards the contraction component through the piston plate, forcing the side wall of the hydraulic telescopic rod to contact the inclined surface of the bevel block. The bevel block is pressed and contracts along the inner wall of the slide rail, enabling the hydraulic telescopic rod to cross the limit of the bevel block. Finally, the side surface of the hydraulic telescopic rod contacts the vertical surface of the bevel block, restricting the reset of the hydraulic telescopic rod and the hydraulic tank. And when the hydraulic tank is restricted, it will also restrict the reset of the contraction component. At this time, when the concrete is poured on the top of the wooden board, through the application of the above components, it effectively avoids the impact force generated by the concrete causing the deformation of the contraction component and the appearance of irregular protrusions on the side wall of the wall panel.

[0011] Preferably, the limiting component further includes two hydraulic telescopic rods connected through the side wall of the hydraulic tank. The other end of the second spring is fixedly connected to the inner wall of the slide rail. When the sliding square rod moves horizontally outward, the sliding square rod drives the piston plate to move outward along the inner wall of the hydraulic tank, forcing the liquid inside the hydraulic telescopic rod to enter the hydraulic tank, and the hydraulic telescopic rod contracts. At this time, the vertical surface of the bevel block will be misaligned with the horizontal surface of the hydraulic telescopic rod, enabling the hydraulic tank to drive the hydraulic telescopic rod to cross the limit of the bevel block.

[0012] Preferably, the limiting component further includes a sliding baffle slidably connected to the side wall of the placement plate. A contact plate is fixedly connected to the side wall of the sliding baffle. A dislocation groove is formed on the side wall of the sliding baffle. By using the above-mentioned third spring, during the demoulding process, it is stretched and extended, and during this process, the third spring will accumulate mechanical power. When the fixed plate drives the push plate to contact the side wall of the contact plate, the contact plate will drive the sliding baffle to move horizontally along the side wall of the placement plate, and force the chute to be in a coincident state with the dislocation groove, as Figure 4 shown. During this process, since the sliding square rod and the roller are restricted by the horizontal surface of the push plate and cannot move, and the chute and the dislocation groove coincide, the sliding baffle will not be able to restrict the slider. Under the pulling of multiple third springs, the slider, the mounting plate and multiple fixed boxes will be forced to move outward, causing the side wall of the fixed box to separate from the side wall of the wall panel. Through the application of the above components, the side wall of the wall panel is completely separated from the inner wall of the equipment.

[0013] A method for using a mold assembly for a prefabricated building wall panel, comprising the following steps:

[0014] S1: Pour cement;

[0015] S2: Cool and shape;

[0016] S3: Demold and form.

[0017] The present invention has the following beneficial effects:

[0018] (1) Aiming at the problem of difficult demolding, a limiting mechanism and a contraction assembly are arranged inside the device. Before use, the base is installed at the required position, the wooden board is placed inside the placement groove, and it is ensured that the sliding baffle and the chute are in an overlapping state, and the electric telescopic rod is in an extended state. At this time, the concrete is poured onto the top of the wooden board. The concrete is restricted by the contraction assembly and the baffle to form a prototype of a wall panel. The side wall of the wall panel contacts the side wall of the contraction assembly. After the concrete is cooled and solidified, the power supply of the electric telescopic rod is turned on. At this time, the electric telescopic rod drives the fixed plate and the push plate to move horizontally, so that the inclined surface contacts multiple rollers, forcing the rollers to drive the sliding square rod to move horizontally. The horizontal movement of the sliding square rod will drive the piston plate to move outward along the inner wall of the hydraulic tank. As the piston plate moves, the piston plate will drive the push rod to move outward synchronously through the first spring. The movement of the push rod will force the contraction assembly to move outward synchronously, forcing the side wall of the contraction assembly to separate from the side wall of the wall panel. Through the application of the above components, the contact area between the wall surface and the device is reduced, and it is avoided that too large a contact area affects the demolding efficiency of the device.

[0019] (2) Utilizing the characteristic that the above-mentioned push rod drives the contraction assembly to move, the contraction assembly is divided into multiple sliding components. Among them, when the push rod moves outward, it will drive the outer sliding square ring four to move synchronously. The horizontal movement of the sliding square ring four will drive the outer sliding square ring three, the sliding square ring three drives the sliding square ring two, and the sliding square ring two drives the sliding square ring one to slide along the inner wall of the fixed box, so that the contraction assembly changes from Figure 7 state G to state F. Through the application of the above components, when the contraction assembly moves away from the wall panel, the contact area with the wall surface will gradually decrease, avoiding too large a single peeling area, resulting in partial peeling of the side wall of the wall panel and causing the side wall of the wall panel to be uneven; in addition, when the sliding square rod moves outward horizontally, the sliding square rod drives the piston plate to move outward along the inner wall of the hydraulic tank, forcing the liquid inside the hydraulic telescopic rod to enter the hydraulic tank, and the hydraulic telescopic rod contracts. At this time, the vertical surface of the inclined block will be misaligned with the horizontal surface of the hydraulic telescopic rod, so that the hydraulic tank can drive the hydraulic telescopic rod to cross the restriction of the inclined block.

[0020] (3) By taking advantage of the feature that the above-mentioned sliding square rod drives the hydraulic tank to move horizontally, a limiting component is arranged inside the equipment. When the equipment has not started demolding, under the pulling of the third spring and the first spring, the sliding square rod forces the piston plate to move inward along the inner wall of the hydraulic tank. During this process, the liquid inside the hydraulic tank is pressurized and enters the inside of the hydraulic telescopic rod, forcing the hydraulic telescopic rod to extend. When the extension is completed, the sliding square rod will drive the hydraulic tank to move towards the contraction component through the piston plate, forcing the side wall of the hydraulic telescopic rod to contact the inclined surface of the inclined block. The inclined block is pressed and contracts along the inner wall of the slide rail, enabling the hydraulic telescopic rod to cross the restriction of the inclined block. Finally, the side surface of the hydraulic telescopic rod contacts the vertical surface of the inclined block, restricting the reset of the hydraulic telescopic rod and the hydraulic tank. And when the hydraulic tank is restricted, it will also restrict the reset of the contraction component. At this time, when the concrete is poured on the top of the wooden board, through the application of the above components, the impact force generated by the concrete is effectively prevented from deforming the contraction component, causing irregular protrusions on the side wall of the wall panel.

[0021] (4) By taking advantage of the above-mentioned third spring that extends under pulling during the demolding process, and during this process, the third spring will accumulate mechanical power. When the fixed plate drives the push plate to contact the side wall of the contact plate, the contact plate will drive the sliding baffle to move horizontally along the side wall of the placement plate, and force the chute and the dislocation groove to be in a coincident state, as Figure 4 shown. During this process, since the sliding square rod and the roller are restricted by the horizontal surface of the push plate and cannot move, and the chute and the dislocation groove coincide, the sliding baffle will not be able to restrict the slider. Under the pulling of multiple third springs, the slider, the mounting plate, and multiple fixed boxes will be forced to move outward, causing the side wall of the fixed box to separate from the side wall of the wall panel. Through the application of the above components, the side wall of the wall panel is completely separated from the inner wall of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Six sliding grooves 15 are formed on the side wall of the placement plate 11. A discharge port 16 is formed on the top of the placement plate 11;

[0039] A power mechanism 2, which includes an electric telescopic rod 21 fixedly connected to the side wall of the base 1. The end of the electric telescopic rod 21 away from the base 1 is fixedly connected to a fixing plate 22. A push plate 23 is fixedly connected to the side wall of the fixing plate 22. An inclined surface 24 is formed at the end of the push plate 23 away from the fixing plate 22;

[0040] A limiting mechanism 3, which includes sliders 31 slidably connected to the inner walls of the six sliding grooves 15. A connecting frame 32 is fixedly connected to the bottoms of the six sliders 31. An installation plate 33 is fixedly connected to the top of the slider 31. A number of fixing boxes 34 are fixedly connected to the top of the installation plate 33. A sliding square rod 35 is slidably connected to the inner wall of the through hole of the fixing box 34. A roller 36 is fixedly connected to the top of the sliding square rod 35. A piston plate 38 is fixedly connected to the end of the sliding square rod 35 away from the roller 36. A first spring 39 is fixedly connected to the side wall of the piston plate 38. The end of the first spring 39 away from the piston plate 38 is fixedly connected to a hydraulic tank 37. A push rod 310 is fixedly connected to the side wall of the hydraulic tank 37. A contraction component 4 is slidably connected to the inner wall of the fixing box 34. A limiting component 5 is fixedly connected to the inner wall of the fixing box 34. To solve the problem of difficult demoulding, a limiting mechanism 3 and a contraction component 4 are provided inside the device. Before use, the base 1 is installed at the required position. The wooden board 13 is placed inside the placement groove 12, and it is ensured that the sliding baffle 55 and the sliding groove 15 are in an overlapping state. The electric telescopic rod 21 is in an extended state. At this time, the concrete is poured onto the top of the wooden board 13. The concrete is restricted by the contraction component 4 and the baffle 14 to form a prototype of a wall panel. The side wall of the wall panel contacts the side wall of the contraction component 4. After the concrete is cooled and solidified, the power supply of the electric telescopic rod 21 is turned on. At this time, the electric telescopic rod 21 drives the fixing plate 22 and the push plate 23 to move horizontally, so that the inclined surface 24 contacts the multiple rollers 36, forcing the rollers 36 to drive the sliding square rod 35 to move horizontally. The horizontal movement of the sliding square rod 35 will drive the piston plate 38 to move outward along the inner wall of the hydraulic tank 37. As the piston plate 38 moves, the piston plate 38 will drive the push rod 310 to move outward synchronously through the first spring 39. The movement of the push rod 310 will force the contraction component 4 to move outward synchronously, forcing the side wall of the contraction component 4 to separate from the side wall of the wall panel. Through the application of the above components, the contact area between the wall surface and the device is reduced, avoiding the large contact area from affecting the demoulding efficiency of the device.

[0041] Example 2. Please refer to Figure 9 - Figure 12 , the present invention is a mold assembly for an assembled building wall panel. On the basis of Example 1, the contraction assembly 4 includes a first sliding square ring 41 slidably connected to the inner wall of the fixed box 34. A second sliding square ring 42 is slidably connected to the inner wall of the first sliding square ring 41. A third sliding square ring 43 is slidably connected to the inner wall of the second sliding square ring 42.

[0042] The contraction assembly 4 further includes a fourth sliding square ring 44 slidably connected to the inner wall of the third sliding square ring 43. The inner wall of the fourth sliding square ring 44 is slidably connected to the outer wall of the push rod 310. A miscellaneous material opening 45 is formed at the bottom of the fixed box 34.

[0043] The contraction assembly 4 further includes a third spring 46 fixedly connected to the side wall of the sliding square rod 35. One end of the third spring 46 away from the sliding square rod 35 is fixedly connected to the side wall of the fixed box 34. The side wall of the piston plate 38 is slidably connected to the inner wall of the hydraulic tank 37. By using the characteristic that the push rod 310 drives the contraction assembly 4 to move, the contraction assembly 4 is divided into multiple sliding components. Among them, when the push rod 310 moves outward, it will drive the outer fourth sliding square ring 44 to move synchronously. The lateral movement of the fourth sliding square ring 44 will drive the outer third sliding square ring 43. The third sliding square ring 43 drives the second sliding square ring 42. The second sliding square ring 42 drives the first sliding square ring 41 to slide along the inner wall of the fixed box 34, so that the contraction assembly 4 changes from Figure 7 state G to state F. Through the application of the above components, when the contraction assembly 4 moves away from the wall panel, the contact area with the wall surface will gradually decrease, avoiding too large a single peeling area, resulting in partial peeling of the side wall of the wall panel and causing the side wall of the wall panel to be uneven;

[0044] The limiting component 5 includes a slide rail 51 fixedly connected to the inner wall of the fixed box 34. A bevel block 52 is slidably connected to the inner wall of the slide rail 51. A second spring 53 is fixedly connected to the side wall of the bevel block 52. Utilizing the characteristic that the above-mentioned sliding square rod 35 drives the hydraulic tank 37 to move horizontally, a limiting component 5 is provided inside the device. When the device has not started demolding, the sliding square rod 35 is pulled by the third spring 46 and the first spring 39, forcing the piston plate 38 to move inward along the inner wall of the hydraulic tank 37. During this process, the liquid inside the hydraulic tank 37 is pressurized and enters the hydraulic telescopic rod 54, forcing the hydraulic telescopic rod 54 to extend. When the extension is completed, the sliding square rod 35 will drive the hydraulic tank 37 to move towards the contraction component 4 through the piston plate 38, forcing the side wall of the hydraulic telescopic rod 54 to contact the inclined surface of the bevel block 52. The bevel block 52 is compressed and contracts along the inner wall of the slide rail 51, enabling the hydraulic telescopic rod 54 to cross the limitation of the bevel block 52. Finally, the side surface of the hydraulic telescopic rod 54 contacts the vertical surface of the bevel block 52, restricting the reset of the hydraulic telescopic rod 54 and the hydraulic tank 37. Since the hydraulic tank 37 is restricted, it will also restrict the reset of the contraction component 4. When the concrete is poured on the top of the wooden board 13 at this time, through the application of the above components, the impact force generated by the concrete is effectively prevented from deforming the contraction component 4, causing irregular protrusions on the side wall of the wall panel.

[0045] The limiting component 5 further includes two hydraulic telescopic rods 54 penetrating and connected to the side wall of the hydraulic tank 37. The other end of the second spring 53 is fixedly connected to the inner wall of the slide rail 51. When the sliding square rod 35 moves horizontally outward, the sliding square rod 35 drives the piston plate 38 to move outward along the inner wall of the hydraulic tank 37, forcing the liquid inside the hydraulic telescopic rod 54 to enter the hydraulic tank 37. The hydraulic telescopic rod 54 contracts. At this time, the vertical surface of the bevel block 52 will be misaligned with the horizontal surface of the hydraulic telescopic rod 54, enabling the hydraulic tank 37 to drive the hydraulic telescopic rod 54 to cross the limitation of the bevel block 52.

[0046] The limiting component 5 further includes a sliding baffle 55 slidably connected to the side wall of the placement plate 11. A contact plate 56 is fixedly connected to the side wall of the sliding baffle 55. A misalignment groove 57 is formed on the side wall of the sliding baffle 55. Utilizing the above-mentioned third spring 46, during the demolding process, it is stretched and extended. During this process, the third spring 46 will accumulate mechanical power. When the fixed plate 22 drives the push plate 23 to contact the side wall of the contact plate 56, the contact plate 56 will drive the sliding baffle 55 to move horizontally along the side wall of the placement plate 11, and force the chute 15 to be in a state of coincidence with the misalignment groove 57, as Figure 4As shown, during this process, since the sliding square rod 35 and the roller 36 are restricted from moving by the transverse surface of the push plate 23, and the sliding groove 15 coincides with the dislocation groove 57, the sliding baffle 55 will not be able to restrict the slider 31. Under the pulling of multiple spring threes 46, it will force the slider 31, the mounting plate 33, and multiple fixed boxes 34 to move outward, causing the side wall of the fixed box 34 to separate from the side wall of the wall panel. Through the application of the above components, the side wall of the wall panel is completely separated from the inner wall of the device.

[0047] The usage method of this mold assembly device includes the following steps:

[0048] S1: Pour cement;

[0049] S2: Cool and set;

[0050] S3: Demold and form.

[0051] A specific application of this embodiment is as follows: Before use, install the base 1 at the required position, place the wooden board 13 inside the placement groove 12, and ensure that the sliding baffle 55 and the sliding groove 15 are in an overlapping state. The electric telescopic rod 21 is in an extended state. At this time, pour the concrete onto the top of the wooden board 13. The concrete is restricted by the shrinkage component 4 and the baffle 14 to form a prototype of a wall panel, and the side wall of the wall panel contacts the side wall of the shrinkage component 4. After the concrete is cooled and solidified, connect the power supply of the electric telescopic rod 21. At this time, the electric telescopic rod 21 drives the fixed plate 22 and the push plate 23 to move horizontally, so that the inclined surface 24 contacts multiple rollers 36, forcing the rollers 36 to drive the sliding square rod 35 to move horizontally. The horizontal movement of the sliding square rod 35 will drive the piston plate 38 to move outward along the inner wall of the hydraulic tank 37. As the piston plate 38 moves, the piston plate 38 will drive the push rod 310 to move outward synchronously through the spring one 39. The movement of the push rod 310 will force the shrinkage component 4 to move outward synchronously, forcing the side wall of the shrinkage component 4 to separate from the side wall of the wall panel. Through the application of the above components, the contact area between the wall surface and the device is reduced, avoiding the influence of too large a contact surface on the demolding efficiency of the device.

[0052] Utilizing the characteristic that the above push rod 310 drives the shrinkage component 4 to move, the shrinkage component 4 is divided into multiple sliding components. Among them, when the push rod 310 moves outward, it will drive the external sliding square ring four 44 to move synchronously. The horizontal movement of the sliding square ring four 44 will drive the external sliding square ring three 43, the sliding square ring three 43 drives the sliding square ring two 42, and the sliding square ring two 42 drives the sliding square ring one 41 to slide along the inner wall of the fixed box 34, so that the shrinkage component 4 moves from Figure 7The state of G changes to the state of F. Through the application of the above components, when the contraction component 4 moves away from the wall panel, the contact area with the wall surface will gradually decrease, avoiding the phenomenon that the area of single peeling is too large, resulting in partial peeling of the side wall of the wall panel and unevenness of the side wall of the wall panel. In addition, when the sliding square rod 35 moves horizontally outwards, the sliding square rod 35 drives the piston plate 38 to move outwards along the inner wall of the hydraulic tank 37, forcing the liquid inside the hydraulic telescopic rod 54 to enter the hydraulic tank 37. The hydraulic telescopic rod 54 contracts. At this time, the vertical surface of the inclined block 52 will be misaligned with the horizontal surface of the hydraulic telescopic rod 54, enabling the hydraulic tank 37 to drive the hydraulic telescopic rod 54 to cross the restriction of the inclined block 52. Using the characteristic that the sliding square rod 35 drives the hydraulic tank 37 to move horizontally, a limiting component 5 is arranged inside the device. When the device has not started demoulding, the sliding square rod 35 is pulled by the third spring 46 and the first spring 39, forcing the piston plate 38 to move inwards along the inner wall of the hydraulic tank 37. During this process, the liquid inside the hydraulic tank 37 is pressurized and enters the hydraulic telescopic rod 54, forcing the hydraulic telescopic rod 54 to extend. When the extension is completed, the sliding square rod 35 will drive the hydraulic tank 37 towards the contraction component 4 through the piston plate 38, forcing the side wall of the hydraulic telescopic rod 54 to contact the inclined surface of the inclined block 52. The inclined block 52 is compressed and contracts along the inner wall of the slide rail 51, enabling the hydraulic telescopic rod 54 to cross the restriction of the inclined block 52. Finally, the side surface of the hydraulic telescopic rod 54 contacts the vertical surface of the inclined block 52, restricting the reset of the hydraulic telescopic rod 54 and the hydraulic tank 37. Since the hydraulic tank 37 is restricted, it will also restrict the reset of the contraction component 4. When the concrete is poured on the top of the wooden board 13 at this time, through the application of the above components, the impact force generated by the concrete is effectively avoided from deforming the contraction component 4 and causing irregular protrusions on the side wall of the wall panel.

[0053] During the demoulding process, the third spring 46 is stretched and extended. During this process, the third spring 46 will accumulate mechanical power. When the fixed plate 22 drives the push plate 23 to contact the side wall of the contact plate 56, the contact plate 56 will drive the sliding baffle 55 to move horizontally along the side wall of the placement plate 11, and force the chute 15 and the dislocation groove 57 to be in a coincident state, as Figure 4 shown. During this process, since the sliding square rod 35 and the roller 36 are restricted by the horizontal surface of the push plate 23 and cannot move, and the chute 15 and the dislocation groove 57 coincide, the sliding baffle 55 will not be able to restrict the slider 31. Under the pulling of multiple third springs 46, the slider 31, the mounting plate 33 and multiple fixed boxes 34 will be forced to move outwards, causing the side wall of the fixed box 34 to separate from the side wall of the wall panel. Through the application of the above components, the side wall of the wall panel is completely separated from the inner wall of the device.
