Description

Technical Field

[0001] This invention belongs to the technical field of concrete slab production equipment, and specifically relates to a mold for manufacturing autoclaved aerated concrete slabs. Background Technology

[0002] In the modern construction industry, autoclaved aerated concrete (AAC) panels are widely used in the walls, roofs, and other structures of various buildings due to their excellent properties such as lightweight, thermal insulation, and sound insulation. However, there are still some problems to be solved in the current manufacturing process of AAC panels, especially in the mold manufacturing stage.

[0003] Existing molds for manufacturing autoclaved aerated concrete (AAC) slabs have significant shortcomings in material addition. Traditional methods mostly involve manual or semi-manual addition of raw materials such as cement, sand, and lime, making precise control of the material addition process difficult. On the one hand, manual operation is highly susceptible to deviations in the amount of each material added due to individual worker differences and fatigue, thus affecting the stability of product quality. For example, excessive cement addition will make the concrete slab too hard and brittle; insufficient lime addition may result in poor curing and failure to meet strength requirements. On the other hand, this inefficient material addition method severely restricts production progress. Adding materials one by one not only consumes a large amount of manpower but also prolongs the production cycle of a single mold, making it difficult to meet the demands of large-scale, high-efficiency modern production.

[0004] Furthermore, traditional mold structures fail to adequately consider the order and process optimization of material addition, resulting in uneven mixing of materials within the mold. This not only affects the consistency of the internal structure of the concrete slab but also reduces the overall performance of the product, such as uneven strength distribution, making it prone to localized damage during use. To address these issues, this invention provides a mold for manufacturing autoclaved aerated concrete (AAC) slabs. Summary of the Invention

[0005] To address the aforementioned technical problems, the technical solution adopted by this invention is: a mold for manufacturing autoclaved aerated concrete (AAC) slabs, comprising an outer frame, with a forming frame fixedly installed inside the outer frame. The forming frame has two sets of symmetrically arranged feeding holes, each set including five feeding holes. Each feeding hole is connected to a feeding pipe. The forming frame has multiple vertical grooves that slide in cooperation with a positioning plate. Four linearly arranged steel mesh sheets are detachably installed on the positioning plate. The raw material for the concrete slab is fed into the forming frame through the feeding pipe, so that the concrete slab is formed between the forming frame and the steel mesh sheets.

[0006] Furthermore, the forming frame is provided with five rectangular grooves arranged linearly along the depth direction of the forming frame. Each rectangular groove is slidably mounted with a closing plate. One side of the closing plate is provided with an inclined surface. The closing plate is slidably engaged with the outer frame, and a return spring is provided between the closing plate and the outer frame.

[0007] Furthermore, a rotating plate is rotatably mounted on the forming frame. The rotating plate is located on the surface of the forming frame opposite to the surface where the rectangular groove is located. The rotating plate is slidably engaged with the telescopic plate. The telescopic plate is fixedly connected to the connecting rod. The connecting rod is fixedly connected to the sliding rod. A circular hole is provided on each side of the sliding rod. Two symmetrically arranged rectangular holes are provided around each circular hole, and the rectangular holes are connected to the circular holes. When the circular holes on the sliding rod are connected to the positioning component, the long side of the rotating plate is parallel to the bottom surface of the outer frame.

[0008] Furthermore, the positioning component includes two symmetrically arranged locking rods, which are slidably mounted on the outer frame. One end of each locking rod is fixedly fitted with a limit block, and the other end of the locking rod is provided with a rotating part. The locking rod is rotated through the rotating part so that the limit block that matches the rectangular hole does not coincide with the rectangular hole.

[0009] Furthermore, the rotating part includes two symmetrically arranged inclined grooves on the locking rod, and a straight groove is arranged between the two inclined grooves. The straight groove is arranged on the locking rod, and both ends of the straight groove are smoothly connected to the two inclined grooves respectively. The locking rod or the inclined groove is slidably engaged with one end of the ball head rod, and the other end of the ball head rod is fixedly connected to the tripod. The tripod is fixedly installed on the outer frame.

[0010] Furthermore, the outer frame is provided with two symmetrically arranged arc-shaped grooves, and a straight groove is provided above the arc-shaped grooves, and the arc-shaped grooves and the straight groove are smoothly connected.

[0011] Furthermore, a baffle is rotatably mounted on the outer frame, and a coil spring is provided at the connection between the baffle and the outer frame. Two positioning rods are fixedly installed on the side of the baffle near the forming frame. Positioning rods 1 and 2 are slidably engaged, and a return spring 2 is provided between positioning rods 1 and 2. A limit plate is fixedly installed on positioning rod 2.

[0012] Furthermore, multiple bolts are fixedly installed on the molding frame, and during the molding process of the concrete slab, the cover plate is fixed to the top of the molding frame by bolts and nuts.

[0013] The beneficial effects of this invention compared with the prior art are: (1) This invention quickly produces concrete blocks by placing steel mesh into a molding frame and adding the raw materials required for concrete blocks into the molding frame in sequence. The structure is simple and easy to use; (2) In the process of producing concrete blocks, this invention adds raw materials into the molding frame in sequence through the feed pipe, and can also pressurize and add air through the feed pipe. On the one hand, it meets the manufacturing requirements, and on the other hand, it can clean the residue of raw materials in the feed pipe by adding air; (3) After the concrete blocks are manufactured, the concrete blocks can be exposed by opening the turntable and baffle, and then the concrete blocks can be taken away by a robot or other equipment with gripping function, which improves the manufacturing efficiency.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figure 1 —— Figure 11 The mold shown includes an outer frame 1, inside which a forming frame 2 is fixedly installed. The forming frame 2 has two sets of symmetrically arranged feeding holes 5, each set of feeding holes 5 including five feeding holes 5. Each feeding hole 5 is connected to a feeding pipe 6. The forming frame 2 has multiple vertical grooves 3, which are slidably engaged with a positioning plate 11. Four linearly arranged steel mesh sheets 12 are detachably installed on the positioning plate 11. The raw material of the concrete slab is fed into the forming frame 2 through the feeding pipe 6 so that the concrete slab is formed between the forming frame 2 and the steel mesh sheets 12.

[0028] like Figure 1 — Figure 5 As shown, the forming frame 2 is fixedly installed on the outer frame 1. During the forming process of the concrete block, the steel mesh 12 is first inserted into the positioning plate 11 along the horizontal grooves on the positioning plate 11. There will be a distance between the four steel mesh 12, and the distance between each two adjacent steel mesh 12 is used to fill the remaining material. After the four steel mesh 12 are pushed into the positioning plate 11, the four positioning plates 11 are aligned with the four vertical grooves 3 on the forming frame 2, and the positioning plates 11 are slid down along the vertical grooves 3, thereby moving the positioning plates 11 and the steel mesh 12 into the interior of the forming frame 2.

[0029] Multiple bolts 4 are fixedly installed on the molding frame 2. During the concrete slab molding process, the cover plate 13 is fixed to the top of the molding frame 2 by the bolts 4 and nuts. After the positioning plate 11 and the steel mesh 12 are placed, the holes on the cover plate 13 are aligned with the bolts 4 on the molding frame 2 so that the cover plate 13 contacts the upper surface of the molding frame 2. Then, the cover plate 13 is fixed to the top of the molding frame 2 by the nuts and bolts 4.

[0030] After the reinforcing mesh 12 and cover plate 13 are arranged, the concrete slab pouring begins. First, the feed pipe 6, connected to the bottommost feed hole 5, is selected. The required material is poured into the feed hole 5 through the feed pipe 6 and flows into the forming frame 2 through the bottommost feed hole 5. At this point, the material enters between the bottommost reinforcing mesh 12 and the forming frame 2. After the material has solidified, the feed pipe 6, connected to the second-to-last feed hole 5, is used to feed material into the forming frame 2. Similarly, after the material solidifies, the next feeding and forming process continues. The entire forming process is performed from bottom to top, pouring sequentially. In addition to the reinforcing mesh 12, the concrete slab materials include cement, sand, lime, etc., all of which enter the forming frame 2 through the feed pipe 6. The reinforcing mesh 12 is treated with anti-corrosion measures.

[0031] After molding is complete, remove the nut from the bolt 4, and then remove the cover plate 13 from above the molding frame 2.

[0032] Autoclaved aerated concrete (AAC) blocks are a new type of green and environmentally friendly building material. They are made primarily from siliceous materials (such as quartz sand, fly ash, and tailings powder) and calcareous materials (such as cement and lime), with the addition of foaming agents (such as aluminum powder) and foam stabilizers. Their density is typically between 300-800 kg / m³, only 1 / 4 to 1 / 5 that of ordinary concrete, effectively reducing the building's self-weight, lowering foundation and structural costs, and facilitating handling and construction.

[0033] During the production process, pressurization is used to make the internal structure of concrete more compact. During autoclaving, a specific pressure environment promotes better hydration of cementitious materials such as cement, generating denser hydration products. These products fill the pores of the concrete, significantly reducing porosity and thus improving the strength and durability of the concrete slab. For example, in practical engineering applications, properly autoclaved concrete slabs are less prone to deformation and cracking when subjected to long-term structural loads, effectively ensuring the safety and stability of the building. Aeration, on the other hand, imparts lightweight and insulating properties to concrete. Adding a foaming agent (such as aluminum powder) to the concrete raw materials causes it to react chemically with alkaline substances to produce hydrogen gas, forming numerous tiny bubbles. These bubbles are evenly distributed throughout the concrete, acting like tiny insulating cavities, significantly reducing the density of the concrete and making it lightweight, thus reducing the overall weight of the building. Simultaneously, the presence of these bubbles increases thermal resistance, greatly improving the thermal insulation performance of the concrete slab. During building use, this effectively reduces heat transfer between indoors and outdoors, lowers building energy consumption, and improves living comfort.

[0034] The forming frame 2 is provided with five rectangular grooves 7 arranged linearly. The rectangular grooves 7 are arranged along the depth direction of the forming frame 2. A closing plate 8 is slidably installed on each rectangular groove 7. A slope 9 is provided on one side of the closing plate 8. The closing plate 8 is slidably engaged with the outer frame 1, and a return spring 10 is provided between the closing plate 8 and the outer frame 1.

[0035] like Figure 1 , Figure 2 , Figure 4 As shown, the molding frame 2 has five rectangular slots 7, each of which slides with a closed plate 8. During the concrete block molding process, in the initial state, the left side of the closed plate 8 (within...) Figure 4 (From a specific perspective) The sealing plate 8 and the molding frame 2 are tightly attached. At this time, the inclined surface 9 on the sealing plate 8 is inserted into the rectangular groove 7, meaning the interior of the molding frame 2 is sealed. After adding material to the molding frame 2 through the feed pipe 6, pressure and gas are added to the molding frame 2 through the feed pipe 6. At this time, the pressure in the uncured material added to the molding frame 2 will increase. When the pressure in the molding frame 2 becomes too high, the pressure will push the sealing plate 8, causing the sealing plate 8 to slide on the outer frame 1. The inclined surface 9 will slide away from the rectangular groove 7, thus gradually moving the inclined surface 9 away from the rectangular groove 7. The original closed state of the molding frame 2 caused by the inclined surface 9 being inserted into the rectangular groove 7 will change, and the gas in the molding frame 2 will flow out through the gap between the sealing plate 8 and the rectangular groove 7. During this process, the return spring 10 will be stretched to generate elastic force. The function of the return spring 10 is to assist the sealing plate 8 in resetting when the pressure in the molding frame 2 equals the external pressure.

[0036] A rotating plate 20 is rotatably mounted on the forming frame 2. The rotating plate 20 is located on the surface of the forming frame 2 opposite to the surface where the rectangular groove 7 is located. The rotating plate 20 is slidably engaged with the telescopic plate 21. The telescopic plate 21 is fixedly connected to the connecting rod 22. The connecting rod 22 is fixedly connected to the sliding rod 23. A circular hole 30 is provided on each side of the sliding rod 23. Two symmetrically arranged rectangular holes 29 are provided around each circular hole 30, and the rectangular holes 29 are connected to the circular hole 30. When the circular hole 30 on the sliding rod 23 is connected to the positioning component, the long side of the rotating plate 20 is parallel to the bottom surface of the outer frame 1. Two symmetrically arranged arc-shaped grooves 32 are provided on the outer frame 1, and a straight groove 33 is provided above the arc-shaped grooves 32. The arc-shaped grooves 32 and the straight groove 33 are smoothly connected.

[0037] like Figure 2 , Figure 6 , Figure 8 , Figure 11 As shown, during the concrete block molding process, the rotating plate 20 is in contact with the molding frame 2, making the interior of the molding frame 2 a sealed space. When the pouring is complete and the concrete block needs to be removed, the rotating plate 20 needs to be rotated relative to the molding frame 2, so that the rotating plate 20 rotates from a vertical position to a horizontal position (e.g., ...). Figure 2 , Figure 6 (The intermediate plate 20 is in a horizontal state). During the process of the intermediate plate 20 changing from a vertical state to a horizontal state, the operator will push the handles at both ends of the sliding rod 23 to push the sliding rod 23 to slide along the arc groove 32 on the outer frame 1, so that the intermediate plate 20 rotates on the forming frame 2. When rotating from a vertical state to a horizontal state, it will first rotate to the upper end of the arc groove 32, where the arc groove 32 makes smooth contact with the straight groove 33. Therefore, the sliding rod 23 is pushed upward to slide upward along the straight groove 33. Since the intermediate plate 20 and the telescopic plate 21 are in sliding fit, there will be relative sliding between the intermediate plate 20 and the telescopic plate 21 at this time, so as to ensure that the sliding rod 23 slides on the straight groove 33. Finally, the sliding rod 23 slides to the positioning component, completing the positioning of the intermediate plate 20 and keeping the intermediate plate 20 in a horizontal state.

[0038] The positioning assembly includes two symmetrically arranged locking rods 26, which are slidably mounted on the outer frame 1. A limit block 31 is fixedly mounted at one end of each locking rod 26, and a rotating part is provided at the other end. This rotating part allows the locking rod 26 to rotate, preventing the limit block 31, which is adapted to the rectangular hole 29, from coinciding with the rectangular hole 29. The rotating part includes two symmetrically arranged inclined grooves 27 on the locking rod 26, with a straight groove 28 positioned between them. The straight groove 28 is mounted on the locking rod 26, and its two ends are smoothly connected to the two inclined grooves 27 respectively. The locking rod 26 or the inclined groove 27 is slidably engaged with one end of a ball joint rod 25, and the other end of the ball joint rod 25 is fixedly connected to a tripod 24, which is fixedly mounted on the outer frame 1.

[0039] like Figure 7 — Figure 10 As shown, during the upward sliding of the sliding rod 23 along the straight groove 23, the upper part of the locking rod 26 is pulled upward, causing the inclined groove 27 located below the locking rod 26 to slide relative to the ball head rod 25. Since the inclined groove 27 is in an inclined state, the ball head rod 25 will cause the locking rod 26 to rotate, so that the limiting block 31 is aligned with a rectangular hole 29. In this way, the circular hole 30 on the sliding rod 23 passes smoothly through the lower part of the locking rod 26, and the rectangular hole 29 passes through the limiting block 31. At this time, the ball head rod 25 moves to the position of the straight groove 28, and the locking rod 26 no longer rotates. When the locking rod 26 moves upward and the inclined groove 27 located below contacts the ball head rod 25, the ball head rod 25 will cause the locking rod 26 to rotate again. In this way, the limiting block 31 will rotate to a position that does not coincide with any of the rectangular holes 29, and at the same time, the end of the inclined groove 27 contacts the ball head rod 25, and the locking rod 26 remains stationary. In this way, the sliding rod 23 is locked by the limiting block 31, and the sliding rod 23 will not drive the rotating plate 20 to move, so that the rotating plate 20 remains in a horizontal state.

[0040] A baffle 14 is rotatably mounted on the outer frame 1. A coil spring 15 is provided at the connection between the baffle 14 and the outer frame 1. Two positioning rods 16 are fixedly mounted on the side of the baffle 14 near the forming frame 2. Positioning rod 16 and positioning rod 2 are slidably engaged. A reset spring 27 is provided between positioning rod 16 and positioning rod 2. A limit piece 19 is fixedly mounted on positioning rod 2.

[0041] like Figure 1 , Figure 6As shown, during the concrete block pouring process, the baffle 14 is in a vertical position. As the rotating plate 20 rotates to the vertical position, the sliding rod 23 also rotates. The sliding rod 23 pushes the limiting plate 19, causing the limiting plate 19 to move the positioning rod 18 away from the positioning rod 16 along the bottom of the outer frame 1. After the sliding rod 23 stops moving, it remains in contact with the limiting plate 19. The purpose of this is to block the limiting plate 19 with the sliding rod 23, preventing the baffle 14 from rotating. This creates a complete space between the baffle 14 and the outer frame 1, ensuring the safety of the surrounding environment. It also prevents the baffle 14 from being accidentally opened during concrete block production, thus avoiding potential hazards to the surrounding environment or people. To improve sealing, the rotating plate 20 can be made of a magnetic material, and the forming frame 2 can also be made of a magnetic material, resulting in a tighter fit between the rotating plate 20 and the forming frame 2.

[0042] After pouring is completed, the rotating plate 20 rotates to a horizontal position. The limiting plate 19 is no longer blocked by the sliding rod 23, allowing the baffle 14 to rotate from a vertical to a horizontal position. The coil spring 15 assists in the reset of the baffle 14. The second positioning rod 18 approaches the first positioning rod 16 under the action of the second reset spring 17. Once both the rotating plate 20 and the baffle 14 are horizontal, the concrete slab in the molding frame 2 can be removed using a robotic arm or similar tool. The bottom of the molding frame 2 can be designed to be smooth to prevent the concrete slab from sticking to the bottom of the molding frame 2, which would affect the removal of the concrete slab. This is existing technology and can be adopted by those skilled in the art.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
