Description

Technical Field

[0001] This utility model relates to the field of concrete brick processing technology, specifically to an aerated concrete brick mold. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a lightweight, porous silicate product made primarily from siliceous and calcareous materials, with the addition of a foaming agent. It is produced through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing. Because it contains a large number of uniform and fine pores after aeration, it is named autoclaved concrete. AAC bricks, also known as autoclaved aerated concrete blocks, are a new type of building material made from AAC, formed through pouring, cutting, and autoclaving. They possess advantages such as being lightweight, porous, and providing thermal insulation. Special molds are required for the pouring of AAC blocks.

[0003] For example, a Chinese patent for an aerated concrete brick mold with publication number CN217573337U uses rollers set around the base plate. Four templates can rotate around the base plate. When they rotate to the top of the base plate, the templates are vertically connected to the side of the base plate, forming a sealed environment between the four templates and the base plate. The handle makes it easy to open the templates, thus enabling personnel to quickly demold the bricks inside the mold.

[0004] However, the aforementioned molds still have certain drawbacks in use. The mold structure itself is not dense enough, which can easily cause concrete to seep out from the gaps between the molds during pouring, affecting the quality of the final product. This seepage not only reduces the strength and performance of aerated concrete blocks, but may also lead to waste of raw materials and reduced production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an aerated concrete brick mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aerated concrete brick mold, comprising a bottom support plate, a restraint frame, and a top closing plate. A bottom mold plate is fixedly installed on the top of the bottom support plate, and four pairs of hinge plates are fixedly installed on the top of the bottom support plate. A hinge seat is rotatably installed inside each of the four pairs of hinge plates, and a side mold plate is fixedly installed on the top of each hinge seat. Four limiting vertical columns are fixedly installed on the inner side of the restraint frame. A threaded ring is fixedly installed on the top of the top closing plate, and a threaded rod is threadedly connected inside the threaded ring. A top mold plate is rotatably installed at the bottom of the threaded rod.

[0007] Preferably, the top of each side mold plate is provided with a circular insertion hole, and the bottom of the top closing plate is fixedly installed with four circular insertion posts.

[0008] Preferably, the positions of the four circular inserts correspond to the positions of the four circular holes, and the outer contour dimensions of the circular inserts match the inner contour dimensions of the bottom mold plate.

[0009] Preferably, both sides of the restraint frame are fixedly equipped with bending handles.

[0010] Preferably, the four limiting vertical posts are located at the contact points of the four side mold plates, and the height of the bottom mold plate is higher than the height of the hinge plate.

[0011] Preferably, a hand-operated handle is fixedly installed on the top of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by installing the restraint frame on the outside of the four side mold plates, the position of the four side mold plates can be precisely and firmly limited, ensuring the stability and accuracy of the mold structure during the subsequent concrete brick pouring process. Furthermore, the four limiting columns can be respectively clamped on the outside of the four side mold plates where they contact each other. The limiting columns not only play the role of supporting and reinforcing the mold frame, but more importantly, they can effectively seal the tiny gaps between the mold plates, thereby building a solid defense line to prevent concrete from accidentally flowing out from these gaps during the subsequent concrete brick pouring operation, which would affect the quality and appearance of the finished product.

[0013] In addition, after the concrete bricks are formed, the top closing plate can be removed from the top of the four side mold plates, and then the restraint frame can be removed from the outside of the four side mold plates. After that, the four side mold plates can be separated by the hinge plate and hinge seat, which facilitates demolding and allows personnel to quickly demold the bricks in the mold.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an aerated concrete brick mold, including a bottom support plate 1, a restraint frame 4, and a top closing plate 10. A bottom mold plate 13 is fixedly installed on the top of the bottom support plate 1. Four pairs of hinge plates 3 are fixedly installed on the top of the bottom support plate 1. A hinge seat 11 is rotatably installed inside each of the four pairs of hinge plates 3. A side mold plate 2 is fixedly installed on the top of each hinge seat 11. Four limiting vertical columns 5 are fixedly installed on the inner side of the restraint frame 4. The four limiting vertical columns 5 are respectively located at the contact points of the four side mold plates 2. The height of the bottom mold plate 13 is higher than the height of the hinge plates 3. A threaded ring 6 is fixedly installed on the top of the top closing plate 10. A threaded rod 7 is threadedly connected inside the threaded ring 6. A top mold plate 14 is rotatably installed at the bottom of the threaded rod 7. A hand handle 8 is fixedly installed on the top of the threaded rod 7.

[0021] The working principle of the above technical solution is as follows: First, the four side mold plates 2 are erected by the cooperation of the hinge plate 3 and the hinge seat 11, thereby assembling the four side mold plates 2 into a rectangular frame. Then, the restraining frame 4 is fitted onto the outside of the four side mold plates 2, which can accurately and firmly limit the position of the four side mold plates 2, ensuring the stability and accuracy of the mold structure during the subsequent concrete pouring process. Furthermore, the four limiting columns 5 can be respectively clamped onto the outside of the four side mold plates 2 where they contact each other. The limiting columns 5 not only play a role in supporting and reinforcing the mold frame, but more importantly, they can effectively seal the tiny gaps between the mold plates, thus building a solid defense line to prevent concrete from accidentally flowing out from these gaps during the subsequent concrete pouring operation, which would affect the finished product. After ensuring quality and appearance, concrete can be poured between the four side mold plates 2, and the top closing plate 10 is placed on top of the four side mold plates 2. The top mold plate 14 is placed between the four side mold plates 2. Then, the hand handle 8 is turned to drive the threaded rod 7 to rotate. With the cooperation of the threaded ring 6, the top mold plate 14 can move downward between the four side mold plates 2, thereby squeezing the concrete and ensuring the normal molding of the concrete bricks. After the concrete bricks are molded, the top closing plate 10 can be removed from the top of the four side mold plates 2, and then the restraining frame 4 can be removed from the outside of the four side mold plates 2. Then, the four side mold plates 2 can be separated by the hinge plate 3 and the hinge seat 11, which facilitates demolding and allows personnel to quickly demold the bricks in the mold.

[0022] In another implementation scheme, such as Figures 1-4 As shown, the top of the side mold plate 2 is provided with a circular insertion hole 12, and the bottom of the top closing plate 10 is fixedly installed with four circular insertion posts 15. The positions of the four circular insertion posts 15 correspond to the positions of the four circular insertion holes 12 respectively, and the specifications of the outer contour of the circular insertion posts 15 match the specifications of the inner contour of the bottom mold plate 13.

[0023] When the top closing plate 10 is placed on top of the four side mold plates 2, the four circular inserts 15 can be inserted into the four circular insert holes 12 to prevent the top closing plate 10 from detaching from the top of the four side mold plates 2. This also helps to restrain the position of the four side mold plates 2 and ensure the normal use of the mold.

[0024] In another implementation scheme, such as Figures 1-4 As shown, both sides of the restraint frame 4 are fixedly equipped with bending handles 9.

[0025] The two bent handles 9 make it easy to pull the restraint frame 4 upward.

[0026] Working Principle: First, the four side mold plates 2 are erected through the cooperation of the hinge plate 3 and the hinge seat 11, thus assembling the four side mold plates 2 into a rectangular frame. Then, the restraining frame 4 is fitted onto the outside of the four side mold plates 2, which can accurately and firmly limit the position of the four side mold plates 2, ensuring the stability and accuracy of the mold structure during the subsequent pouring of concrete bricks. The four limiting columns 5 can be respectively clamped onto the outside of the four side mold plates 2 where they contact each other. The limiting columns 5 not only support and reinforce the mold frame, but more importantly, they can effectively seal the tiny gaps between the mold plates, thus building a solid defense to prevent concrete from accidentally flowing out of these gaps during the subsequent pouring of concrete bricks, affecting the quality and appearance of the finished product. Then, concrete can be poured between the four side mold plates 2, and the top closing plate 10 is placed on top of the four side mold plates 2, and the top... The mold plate 14 is placed between the four side mold plates 2. Then, the hand handle 8 is turned to drive the threaded rod 7 to rotate. With the cooperation of the threaded ring 6, the top mold plate 14 can move downward between the four side mold plates 2, thereby squeezing the concrete and ensuring the normal molding of the concrete bricks. After the concrete bricks are molded, the top closing plate 10 can be removed from the top of the four side mold plates 2. Then, the restraining frame 4 can be removed from the outside of the four side mold plates 2. Afterward, the four side mold plates 2 can be separated by the hinge plate 3 and the hinge seat 11, which facilitates demolding. This allows personnel to quickly demold the bricks in the mold. When the top closing plate 10 is placed on the top of the four side mold plates 2, the four circular inserts 15 can be inserted into the four circular insert holes 12 to prevent the top closing plate 10 from detaching from the top of the four side mold plates 2. This also restrains the position of the four side mold plates 2 and ensures the normal use of the mold.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
