Description

Technical Field

[0001] The utility model belongs to the technical field of wall panel demoulding, and particularly relates to a rapid demoulding device for precast wall panels. Background Technique

[0002] Precast wall panels are reinforced concrete slab-shaped components processed in precast factories or construction sites for building assembly, simply referred to as wall panels or wallboards. Concrete is poured into a specific mold, and after the concrete solidifies, precast wall panels are formed.

[0003] At present, after the wall panels solidify and form, they need to be demoulded. Concrete has strong adhesiveness, and it is laborious to demould it from the mold after it solidifies. Moreover, when users demould the wall panels, they may damage the wall panels. In order to avoid damage to the wall panels during demoulding, reduce the time consumed for wall panel demoulding, and improve production efficiency, a rapid demoulding device for precast wall panels is needed. The mold can be removed through an extension device, avoiding the need for users to use crowbars and hammers to demould the wall panels, preventing damage to the wall panels during demoulding, and improving the production efficiency of wall panels. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rapid demoulding device for precast wall panels, which has the purpose of being able to remove the mold through an extension device, avoiding the need for users to use crowbars and hammers to demould the wall panels, preventing damage to the wall panels during demoulding, and improving the production efficiency of wall panels, so as to solve the above-mentioned background technical problems.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A rapid demoulding device for precast wall panels includes a fixing plate. A sliding frame is welded to the top of the inner cavity of the fixing plate. A bidirectional threaded rod is rotatably connected to the inner cavity of the fixing plate.

A first slider is rotatably connected to the inner cavity of the sliding frame. The first slider is threadedly connected to the bidirectional threaded rod. A rotating plate is rotatably connected to the top of the inner cavity of the fixing plate. Connecting rods are rotatably connected to both ends of the rotating plate. The other end of the connecting rod is welded with a second slider. Two symmetrical sliding grooves are opened at the top of the fixing plate. The second slider slides in the inner cavity of the sliding groove. Two symmetrical openings are opened at the bottom of the inner cavity of the fixing plate. A first sliding plate slides in the inner cavity of the opening. The first sliding plate is threadedly connected to the bidirectional threaded rod. The first sliding plate is slidably connected to the sliding rod. A fixing rod is welded to the top of the first slider. A deflection groove is opened at the top of the rotating plate. The fixing rod is adapted to the deflection groove. The top of the second slider penetrates through the top of the fixing plate and is welded with a second sliding plate.

[0006] Preferably, a motor is fixedly installed on the front surface of the fixing plate through bolts. The output shaft of the motor penetrates into the inner cavity of the fixing plate and is fixedly connected to the bidirectional threaded rod.

[0007] Preferably, limiting grooves are formed on both sides of the inner cavity of the carriage, limiting blocks are welded on both sides of the first slider, and the limiting grooves are adapted to the limiting blocks.

[0008] Preferably, four symmetric templates are arranged on the top of the fixing plate, and one side of the first slide plate and the second slide plate close to the rotating plate are fixedly connected to the templates.

[0009] Preferably, the lengths of the two sections of threads provided on the surface of the bidirectional threaded rod are different.

[0010] 1. The beneficial effects of the present utility model are as follows: After the concrete solidifies, the motor is started, and the motor drives the bidirectional threaded rod to rotate, causing the first slide plate to move away from each other. At the same time, the first slider drives the second slide plate to move away from each other through the connecting rod. Furthermore, the first slide plate and the second slide plate drive the templates to move away from each other, so that the mold can be removed by the stretching device, avoiding the user having to use a crowbar and a hammer to demold the wall panel, preventing damage to the wall panel during demolding, and improving the production efficiency of the wall panel.

[0011] 2. Through the arrangement of the deflection groove in the present utility model, when the fixing rod moves in the inner cavity of the deflection groove, it will deflect, avoiding the situation where the fixing rod cannot deflect in the inner cavity of the deflection groove, so that the fixing rod cannot drive the rotating plate to rotate through the deflection groove.

[0012] 3.

[0021] Embodiment 1:

[0022] Figures 1-4 A rapid demoulding device for precast wall panels showing an embodiment of the present utility model includes: a fixed plate 1. Four symmetric templates are provided at the top of the fixed plate 1. The sides of the first slide plate 11 and the second slide plate 14 close to the rotating plate 6 are fixedly connected to the templates. The front of the fixed plate 1 is fixedly installed with a motor 15 through bolts. The output shaft of the motor 15 penetrates into the inner cavity of the fixed plate 1 and is fixedly connected to the bi-directional threaded rod 3. The top of the inner cavity of the fixed plate 1 is welded with a slide carriage 2. Limiting grooves 16 are provided on both sides of the inner cavity of the slide carriage 2. Limiting blocks 17 are welded on both sides of the first slider 5. The limiting grooves 16 are adapted to the limiting blocks 17. By the combined use of the limiting grooves 16 and the limiting blocks 17, the first slider 5 is limited, preventing the first slider 5 from shifting when driving the rotating plate 6 to rotate, preventing the bi-directional threaded rod 3 from breaking, and improving the sliding stability of the first slider 5. The bi-directional threaded rod 3 is rotatably connected to the inner cavity of the fixed plate 1. The lengths of the two sections of threads provided on the surface of the bi-directional threaded rod 3 are different. The bi-directional threaded rod 3 penetrates through the slide carriage 2. The slide rod 4 is welded in the inner cavity of the fixed plate 1. The first slider 5 is rotatably connected to the inner cavity of the slide carriage 2. The first slider 5 is threadedly connected to the bi-directional threaded rod 3. The rotating plate 6 is rotatably connected to the top of the inner cavity of the fixed plate 1. Connecting rods 7 are rotatably connected to both ends of the rotating plate 6. The other ends of the connecting rods 7 are welded with the second slider 8. Two symmetric chutes 9 are provided at the top of the fixed plate 1. The second slider 8 slides in the inner cavity of the chute 9. Two symmetric openings 10 are provided at the bottom of the inner cavity of the fixed plate 1. The first slide plate 11 slides in the inner cavity of the opening 10.

The fixed rod 12 is welded to the top of the first slider 5. The deflection groove 13 is provided at the top of the rotating plate 6. Through the setting of the deflection groove 13, when the fixed rod 12 moves in the inner cavity of the deflection groove 13, it will shift, preventing the fixed rod 12 from being unable to shift in the inner cavity of the deflection groove 13, so that the fixed rod 12 cannot drive the rotating plate 6 to rotate through the deflection groove 13. The fixed rod 12 is adapted to the deflection groove 13. The top of the second slider 8 penetrates through the top of the fixed plate 1 and is welded with the second slide plate 14.

[0023] Working principle: When the utility model is in use, the user starts the motor 15 after the concrete solidifies, causing the bidirectional threaded rod 3 to rotate, making the first slide plate 11 move away from each other. The bidirectional threaded rod 3 will drive the first slider 5 to slide in the inner cavity of the carriage 2, enabling the first slider 5 to drive the rotating plate 6 to rotate through the cooperation of the fixed rod 12 and the deflection groove 13. The rotating plate 6 will drive the connecting rod 7 to move, and the other end of the connecting rod 7 will drive the second slider 8 to move. Limited by the chute 9, the second slider 8 drives the second slide plate 14 to move away from each other. Furthermore, the first slide plate 11 and the second slide plate 14 drive the formwork to move away from each other, removing the formwork, which facilitates the user to demold the wall panel. Through the combined use of the limiting groove 16 and the limiting block 17, the first slider 5 is limited, preventing the first slider 5 from shifting when driving the rotating plate 6 to rotate and improving the sliding stability of the first slider 5.

[0024] In summary: For this rapid demolding device for precast wall panels, by starting the motor 15 after the concrete solidifies, the motor 15 drives the bidirectional threaded rod 3 to rotate, making the first slide plate 11 move away from each other. At the same time, the first slider 5 drives the second slide plate 14 to move away from each other through the connecting rod 7. Furthermore, the first slide plate 11 and the second slide plate 14 drive the formwork to move away from each other, achieving the purpose of being able to remove the mold through the stretching device, avoiding the user having to use a crowbar and a hammer to demold the wall panel, preventing damage to the wall panel during demolding, and improving the production efficiency of the wall panel.
