Description

Technical Field

[0001] This application relates to the field of concrete casting mold technology, and in particular to a self-locking concrete casting mold. Background Technology

[0002] Concrete casting molds are tools used to create concrete components on a construction site. They are typically made of steel plates, wood boards, or other suitable materials, and their function is to provide a space that defines the shape of the concrete, allowing it to maintain a specific shape and size during the setting process.

[0003] In practical use, we have found that traditional concrete casting molds face many problems: First, their sealing performance is insufficient, and gaps easily appear at the joints of the molds, leading to grout leakage during concrete pouring. This not only wastes materials but also affects the appearance quality and structural integrity of the components, increasing the cost of later repairs. Second, the fixing methods mostly rely on bolts, clips, and other manually fastened parts, making the installation and disassembly process cumbersome and consuming a lot of manpower and time. This is difficult to meet the needs of efficient construction in modern engineering, and frequent disassembly and assembly can easily lead to wear and tear on parts, reducing the service life of the mold. Third, during the demolding process, there is a lack of reasonable auxiliary mechanisms. It is often necessary to manually pry or forcibly separate the concrete components from the mold with simple tools. This is not only labor-intensive but also easily damages the surface of the mold and the concrete components, affecting the accuracy of the components and the turnover of the mold. Therefore, we propose a self-locking concrete casting mold to solve the above problems. Utility Model Content

[0025] See Figures 1-4 This application provides a self-locking concrete pouring mold, including a mold base 1, a support box 2 above the mold base 1, a back plate 3 fixedly installed on the back side of the support box 2 and the mold base 1, an ejection mechanism on the mold base 1, a rotating shaft 201 rotatably installed on the inner walls of both sides of the support box 2, the right end of the rotating shaft 201 penetrating the right side of the support box 2, and a rocking mechanism at the right end of the rotating shaft 201; a cover plate 4 below the support box 2, a lifting mechanism between the cover plate 4 and the support box 2, fixed plates 5 fixedly installed on both sides of the cover plate 4, piston cylinders 6 fixedly installed on both sides of the mold base 1, a piston mechanism between the piston cylinders 6 and the fixed plates 5, an air bladder groove at the bottom of the cover plate 4, a sealing mechanism between the air bladder groove and the piston cylinder 6, support legs at the four corners of the bottom of the mold base 1, a groove at the front of the back plate 3, a limit mechanism in the groove, and a pouring pipe 7 at the top of the cover plate 4.

[0028] Specifically, the lifting mechanism includes a threaded cylinder 401 and a screw 402. The threaded cylinder 401 is fixedly installed on the top of the cover plate 4. The threaded cylinder 401 is located outside the casting pipe 7. The screw 402 is rotatably installed at the bottom of the support box 2. The top of the screw 402 extends into the support box 2. The threaded cylinder 401 is located on the screw 402. A gear mechanism is provided between the screw 402 and the rotating shaft 201.

[0029] Specifically, the gear mechanism includes a first bevel gear 204 and a second bevel gear 205. The first bevel gear 204 is fixedly sleeved on the rotating shaft 201, and the second bevel gear 205 is fixedly sleeved on the top end of the screw 402. The first bevel gear 204 and the second bevel gear 205 mesh with each other.

[0030] Specifically, the piston mechanism includes a piston plate 601 and a piston rod 602. The piston plate 601 is slidably installed inside the piston cylinder 6, and the piston rod 602 is fixedly installed on the top of the piston plate 601. The top of the piston rod 602 is fixedly connected to the bottom of the fixed plate 5.

[0031] Specifically, the sealing mechanism includes a sealing airbag 403 and a ventilation hose 404. The sealing airbag is installed in the airbag groove. The same ventilation hose 404 is installed between the sealing airbag 403 and the piston cylinder 6. The bottom end of the ventilation hose 404 is located below the piston plate 601. The sealing airbag 403 is adapted to the mold base 1.

[0032] Specifically, the limiting mechanism includes a slide plate 8, a limiting rod 801, a spring 802, and a pull button 803. The slide plate 8 is slidably installed in the groove. The limiting rod 801 is fixedly installed on the right side of the slide plate 8. The left end of the limiting rod 801 extends to the left side of the slide plate 8. The spring 802 is sleeved on the limiting rod 801. The two ends of the spring 802 are fixedly connected to the right side of the slide plate 8 and the inner wall of the right side of the groove, respectively. The right end of the limiting rod 801 passes through the right side of the back plate 3. The pull button 803 is provided at the right end of the limiting rod 801. The left end of the limiting rod 801 is provided with a slope. The cover plate 4 is adapted to the slope.

[0033] In this application, when using the self-locking concrete pouring mold, the operator first holds the handle 203 and turns the rocker wheel 202, which can drive the rotating shaft 201 to rotate. This can drive the screw 402 to rotate through the first bevel gear 204 and the second bevel gear 205, which can drive the threaded cylinder 401 to move downward, thereby driving the cover plate 4 to move downward smoothly, so as to achieve a tight fit between the cover plate 4 and the mold base 1, and complete the initial closing of the mold. During the descent of the cover plate 4, the guide action of the inclined plane can push the limiting rod 801 to move to the right against the elastic force of the spring 802, making room for the descent of the cover plate 4; when the cover plate 4 reaches the predetermined position, the limiting rod 801 moves to the left under the restoring force of the spring 802, accurately engaging the corresponding limiting part of the cover plate 4, which can firmly limit the cover plate 4 from the top, and can prevent it from moving upward due to pressure during the concrete pouring process, ensuring the stability of the mold structure and avoiding grout leakage. At the same time, the fixing plates 5 on both sides of the cover plate 4 descend with the cover plate 4, which can drive the piston rod 602 to move downward. The piston rod 602 can push the piston plate 601 inside the piston cylinder 6 to move downward synchronously. The piston plate 601 presses the air below it into the sealing airbag 403 through the ventilation hose 404, which can make the sealing airbag 403 gradually expand and tightly fit the edge of the mold seat 1 to form a reliable sealing barrier, further enhancing the sealing performance of the mold. This can ensure that the concrete pouring process is carried out in a closed environment and effectively improve the molding quality of the concrete components. Once the concrete pouring is complete and the demolding strength is reached, pulling the button 803 will cause the limit rod 801 to move to the right against the elastic force of the spring 802, releasing the limit on the cover plate 4. Then, the rocker wheel 202 will rotate in the opposite direction, and through the coordinated action of the gear mechanism and the lifting mechanism, the cover plate 4 will rise and reset. The air in the sealing airbag 403 will flow back to the piston cylinder 6 through the ventilation hose 404 under the action of pressure difference, preparing for the next pouring operation. Then, by activating the hydraulic cylinder 101 of the ejection mechanism, the output shaft of the hydraulic cylinder 101 will extend, which can push the top plate 102 upward, so that the concrete product can be smoothly ejected from the mold seat 1 through the top plate 102, completing the demolding operation.
