Description

Technical Field

[0001] This utility model relates to the field of casting mold frame technology, and in particular to a casting mold frame for autoclaved aerated concrete blocks. Background Technology

[0002] As a lightweight and porous new building material, the industrial production process of aerated concrete blocks mainly includes the following key steps: First, the raw materials such as lime, cement and tailings rich in quartz are precisely proportioned and pretreated; then, the mixture is stirred into a uniform block slurry, foamed by an aerator and injected into a specially made casting mold; after static curing and defoaming treatment, the entire mold is flipped to the cutting station for precise cutting of the formed blocks.

[0003] In existing production processes, casting mold frames typically adopt two structural forms: one is a modular design, which consists of five sets of detachable templates assembled into an open cuboid structure, facilitating demolding or transportation; the other is an integrated design, which welds the side plates and the base into an integral mold frame.

[0004] It is worth noting that the currently widely used splicing mold frame has obvious technical defects: its smooth edge design makes it easy for assembly gaps to be generated at the joint of the mold. This structural problem not only damages the sealing performance of the pouring process, but may also cause process accidents such as slurry leakage. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the smooth edge design of traditional mold frames in the prior art easily leads to assembly gaps at the joint of the molds, and to propose a mold frame for casting autoclaved aerated concrete blocks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A casting mold frame for autoclaved aerated concrete (AAC) blocks includes a base plate. At least one pair of long side plates and short side plates are detachably connected to the top surface of the base plate. The long and short side plates are connected by a corner locking mechanism. A first groove extending along the length direction is formed on the long and short sides of the base plate. A sealing gasket is placed in the first groove. When the bottom ends of the long and short side plates abut against the sealing gaskets, the sealing gaskets fill the first grooves, forming a sealing structure between the top surface of the base plate and the bottom of the long and short side plates. A second groove extending vertically is formed in the middle of the outer side wall of the short side plate. A sealing gasket is placed in the second groove. When the outer wall of the long side plate abuts against the sealing gasket, a sealing structure is formed between the short and long side plates.

[0008] To facilitate the detachable connection between the long side plate and the short side plate, preferably, the corner locking mechanism includes a wedge-shaped locking block disposed at the end of the long side plate, and a wedge-shaped groove is provided on the short side plate, and the wedge-shaped locking block is engaged with the wedge-shaped groove.

[0009] To improve the stability between the long and short side plates, the wedge groove and the wedge block are further fixedly connected by locking bolts.

[0010] To facilitate a stable connection between the bottom of the long side plate and the short side plate, preferably, the long side and the short side of the base plate are respectively provided with limiting grooves extending along the length direction, and the bottom of the long side plate and the short side plate are respectively fixedly connected with a first limiting block and a second limiting block, and the first limiting block and the second limiting block are both engaged in the limiting groove.

[0011] To facilitate the positioning and fixing of the short side plate, preferably, a locking groove is provided on the short side wall of the base plate, and the short side plate is engaged and connected in the locking groove by a connecting plate.

[0012] Furthermore, the locking groove and the connecting plate are provided with corresponding locking holes, and bolts are threaded onto the locking holes.

[0013] Compared with the prior art, this utility model provides a casting mold frame for autoclaved aerated concrete blocks, which has the following beneficial effects:

[0014] 1. The autoclaved aerated concrete block casting mold frame has a sealing gasket at the bottom of the long side plate and the short side plate. The sealing gasket fills the first groove, so that the top surface of the bottom plate and the bottom of the long side plate and the short side plate form an effective sealing structure. This design not only improves the sealing performance of the long side plate and the short side plate, but also reduces leakage during the casting process.

[0015] 2. The autoclaved aerated concrete block casting mold frame, by abutting the outer wall of the long side plate with the sealing gasket, forms an effective sealing structure between the short side plate and the long side plate. This design ensures the sealing performance of the mold frame, prevents leakage of the mixture during the casting process, and improves the practicality of the device.

[0016] 3. The autoclaved aerated concrete block casting mold frame, through the design of the corner locking mechanism, can ensure the tightness and structural stability of the combination between the long side plate and the short side plate, enhance the overall connection rigidity of the device, and reduce production problems caused by structural instability.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model can form an effective sealing mechanism between the short side plate, the long side plate and the bottom plate, thereby greatly reducing leakage during the casting process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-5A casting mold for autoclaved aerated concrete (AAC) blocks is described. In the production process of AAC, the raw materials, including lime, cement, and tailings rich in quartz, are first precisely proportioned and pretreated. Then, the mixture is stirred into a uniform block slurry, foamed using an aerator, and poured into a specially designed casting mold. After static curing and defoaming, the entire mold is flipped to the cutting station for precise cutting of the formed blocks. However, the casting mold typically employs two structural forms: one is a modular design consisting of five sets of... One design involves disassembling and assembling the templates to form an open cuboid structure, facilitating demolding or transportation. Another design is an integrated one, where the side plates and base are welded together to form a single mold frame. This device is designed for a detachable casting mold frame, including a base plate 1. At least one pair of long side plates 5 and short side plates 8 are detachably connected to the top surface of the base plate 1. The long side plates 5 and short side plates 8 are connected by a corner locking mechanism to ensure a tight fit and structural stability. The base plate 1 has openings along its length on both its long and short sides. The extended first groove 2 contains a sealing gasket. When the bottom ends of the long side plate 5 and the short side plate 8 abut against the sealing gasket, the gasket fills the first groove 2, forming a sealing structure between the top surface of the base plate 1 and the bottom of the long side plate 5 and the short side plate 8. During assembly, when the bottom ends of the long side plate 5 and the short side plate 8 abut against the sealing gasket, the gasket fills the first groove 2, thus forming an effective sealing structure between the top surface of the base plate 1 and the bottom of the long side plate 5 and the short side plate 8. This design not only improves the sealing structure between the long side plate 5 and the short side plate 8... To improve sealing performance and reduce leakage during casting, a vertically extending second groove 9 is provided in the middle of the outer side wall of the short side plate 8. A sealing gasket is placed in the second groove 9. When the outer wall of the long side plate 5 abuts against the sealing gasket, a sealing structure is formed between the short side plate 8 and the long side plate 5. When the outer wall of the long side plate 5 touches against the sealing gasket, an effective sealing structure is formed between the short side plate 8 and the long side plate 5. This design ensures the sealing performance of the mold frame, prevents leakage of the mixture during casting, and improves the practicality of the device.

[0028] In the above scheme, by setting a sealing gasket on the first groove 2 opened on the long and short sides of the base plate 1, the sealing effect between the bottom ends of the long side plate 5 and the short side plate 8 and the top surface of the base plate 1 can be improved. When the bottom ends of the long side plate 5 and the short side plate 8 abut against the sealing gasket, the first groove 2 is effectively filled, thereby forming a reliable sealing structure. At the same time, when the outer wall of the long side plate 5 abuts against the sealing gasket, an effective sealing mechanism is formed between the short side plate 8 and the long side plate 5, thereby greatly reducing leakage during the casting process.

[0029] In addition, the corner locking mechanism design ensures the tightness and structural stability of the combination between the long side plate 5 and the short side plate 8, enhances the overall connection rigidity of the device, and reduces production problems caused by structural instability.

[0030] Furthermore, the aforementioned corner locking mechanism includes a wedge-shaped locking block 6 disposed at the end of the long side plate 5, and a wedge-shaped groove 10 provided on the short side plate 8. The wedge-shaped locking block 6 engages with the wedge-shaped groove 10. The wedge-shaped locking block 6 is installed at the end of the long side plate 5. Through the wedge design, its shape allows it to effectively cooperate with the wedge-shaped groove 10 of the short side plate 8 in the fixed state, thereby providing a larger contact area, enhancing the stability and tightness of the connection, and making the combination of the two more secure.

[0031] When the wedge-shaped locking block 6 on the long side plate 5 is inserted into the wedge-shaped groove 10, the wedge-shaped groove 10 and the wedge-shaped locking block 6 are then fixedly connected by locking bolts, thereby achieving precise positioning and docking, effectively reducing the gaps that may occur during assembly, and the wedge locking mechanism makes the assembly and disassembly of the mold frame easier, allowing operators to quickly complete assembly or disassembly and improve production efficiency.

[0032] The base plate 1 has a limiting groove 3 extending along the length direction on its long side and short side respectively. The bottom of the long side plate 5 and the short side plate 8 are respectively fixedly connected to the first limiting block 7 and the second limiting block 11. The first limiting block 7 and the second limiting block 11 are both engaged in the limiting groove 3. The cooperation between the limiting groove 3 and the first limiting block 7 and the second limiting block 11 ensures that the mold frame is not easily deformed or misaligned when it encounters external force or internal pressure, thus enhancing the stability of the overall structure.

[0033] A locking groove 4 is provided on the short side wall of the base plate 1. The short side plate 8 is engaged and connected in the locking groove 4 by the connecting plate 12. Corresponding locking holes are provided on the locking groove 4 and the connecting plate 12, and bolts are threaded on the locking holes.

[0034] When the long side plate 5, short side plate 8, and base plate 1 of the device need to be connected by snapping, the two sides of the long side plate 5 are first snapped into the wedge grooves 10 on the short side plate 8 by wedge-shaped snapping blocks 6. During this process, sealing gaskets need to be placed in the first groove 2 and the second groove 9. The sealing gaskets can be made of rubber. After the long side plate 5 and the short side plate 8 are connected, the wedge-shaped snapping blocks 6 are fixedly installed on the short side plate 8 by locking bolts to form a frame. Then, the first limiting block 7 and the second limiting block 11 of the long side plate 5 and the short side plate 8 are snapped into the limiting grooves 3 on the base plate 1. At this time, the connecting plate 12 is fixedly connected to the locking groove 4 by locking bolts. During this process, the sealing gaskets in the first groove 2 and the second groove 9 are compressed, thereby forming a reliable sealing structure, which greatly reduces leakage during the casting process.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
