Description

Technical Field

[0001] This utility model relates to the field of concrete block mold technology, and in particular to an autoclaved aerated concrete block mold. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made primarily from fly ash, lime, cement, gypsum, and slag, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers. The process involves batching, mixing, pouring, static curing, cutting, and high-pressure autoclaving. Molds for AAC block production are used to manufacture these concrete blocks.

[0003] In the existing technology patent CN220008198U, an autoclaved aerated concrete block mold is disclosed. By setting a bidirectional screw to drive the second side plate to move, the size of the mold can be adjusted, and concrete blocks of different sizes can be produced. It is simple to operate, saves production costs and time. The extrusion plate and extension plate are detachably connected by bolts, and the extension length of the extension plate can be adjusted according to the size of the production mold, so that it fits better when extruding the mold. A stop block and a first spring are set. After the block solidifies, the elasticity of the first spring can push the stop block out of the mold, which is convenient for removal.

[0004] In the existing method described above, a spring and a stop block are used to push the solidified block out of the mold. However, because the block is large and heavy, the spring force is limited and it will remain compressed under the weight of the block, making it difficult to push the block out smoothly, which is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a mold for autoclaved aerated concrete blocks, which solves the problem in the prior art where a spring and a stop block are used to push the solidified blocks out of the mold. However, due to the large size and weight of the blocks, the spring force is limited and the blocks remain compressed under the weight of the blocks, making it difficult to push the blocks out smoothly and causing inconvenience.

[0006] To achieve the above objectives, this utility model employs an autoclaved aerated concrete (AAC) block mold, comprising a base, a support, two first side plates, two second side plates, an electric push rod, an extrusion plate, two extension plates, an adjustment assembly, and a feeding assembly. The support is fixedly disposed above the base, both first side plates are fixedly disposed above the base, and both second side plates are located above the base. The electric push rod is fixedly connected to the support, and the extrusion plate is fixedly connected to the output end of the electric push rod. Both ends of each extension plate are movably connected to the extrusion plate and the second side plates, respectively. The adjustment assembly... The component is disposed within the bracket and connected to the two second side plates. The pushing assembly includes a drive unit, a first bidirectional lead screw, two sleeves, two connecting rods, a top plate, and two rotating seats. Both rotating seats are rotatably connected to the base and are located within the base. The two ends of the first bidirectional lead screw are fixedly connected to the two rotating seats. Both sleeves are sleeved on the outside of the first bidirectional lead screw and are threadedly engaged with the first bidirectional lead screw. The top plate is movably connected to the base and movably passes through the base. The two ends of each connecting rod are rotatably connected to the top plate and the corresponding sleeve, respectively.

[0007] The drive unit includes a first motor, a first bevel gear, and a second bevel gear. The first motor is fixedly connected to the base and located inside the base. The first bevel gear is fixedly connected to the output end of the first motor. The second bevel gear is fixedly connected to the first bidirectional lead screw and sleeved in the middle of the first bidirectional lead screw, and the second bevel gear meshes with the first bevel gear.

[0008] The material pushing assembly further includes a maintenance plate and a fixing component. The maintenance plate is located on the outside of the base, and the fixing component is connected to the maintenance plate and the base respectively.

[0009] The fixing component includes two first magnetic blocks and two second magnetic blocks. The two first magnetic blocks are fixedly connected to the base and are embedded in the outer side of the base. The two second magnetic blocks are fixedly connected to the inspection plate and are embedded in the inner side of the inspection plate. Each second magnetic block is magnetically attracted to the first magnetic block.

[0010] The adjustment assembly includes two fastening bolts, a second bidirectional lead screw, a guide rod, and a second motor. The second motor is fixedly mounted on the outside of the bracket. The second bidirectional lead screw is rotatably mounted inside the bracket and connected to the output end of the second motor. The guide rod is fixedly mounted inside the bracket. Two second side plates are respectively sleeved on the outside of the second bidirectional lead screw and the guide rod, and are threadedly engaged with the second bidirectional lead screw. Each extension plate has multiple adjustment holes. Each fastening bolt movably passes through the extrusion plate and is connected to multiple adjustment holes.

[0011] This utility model discloses an autoclaved aerated concrete (AAC) block mold. Two first side plates and two second side plates form the mold. In use, the position of the two second side plates within the two first side plates is adjusted using an adjustment assembly. Simultaneously, the adjustment assembly moves the extension plate towards the extrusion plate. After adjusting the mold to the appropriate position, concrete is added to the mold. The electric push rod is activated, causing the extrusion plate to move downwards and extrude the concrete. After the block solidifies, the extrusion plate is moved upwards to its original position. Then, the drive unit within the base is activated, causing the first bidirectional lead screw to rotate within the base. Since the two sleeves are threaded into the first bidirectional lead screw, the two sleeves move relative to each other on the first bidirectional lead screw. The two connecting rods push the top plate upwards, and subsequently, the top plate ejects the block from the mold. This method allows for convenient ejection of the block from the mold, making it very convenient to use. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a mold for autoclaved aerated concrete (AAC) blocks, comprising a base 101, a support 102, two first side plates 103, two second side plates 120, an electric push rod 104, an extrusion plate 105, two extension plates 106, an adjustment assembly, and a feeding assembly. The support 102 is fixedly disposed above the base 101, both first side plates 103 are fixedly disposed above the base 101, and both second side plates 120 are located above the base 101. The electric push rod 104 is fixedly connected to the support 102, and the extrusion plate 105 is fixedly connected to the output end of the electric push rod 104. Both ends of each extension plate 106 are movably connected to the extrusion plate 105 and the second side plate 120, respectively. The adjustment assembly is disposed within the support 102 and is connected to the two second side plates. The feeding assembly, connected in 120, includes a drive unit, a first bidirectional lead screw 107, two sleeves 108, two connecting rods 109, a top plate 110, and two rotating seats 111. Both rotating seats 111 are rotatably connected to the base 101 and are located within the base 101. The two ends of the first bidirectional lead screw 107 are fixedly connected to the two rotating seats 111. The two sleeves 108 are sleeved on the outside of the first bidirectional lead screw 107 and threadedly engaged with it. The top plate 110 is movably connected to the base 101 and extends through it. The two ends of each connecting rod 109 are rotatably connected to the top plate 110 and the corresponding sleeve 108, respectively. The drive unit is fixedly disposed within the base 101 and connected to the first bidirectional lead screw 107.

[0020] In this embodiment, the two first side plates 103 and the two second side plates 120 form a mold. During use, the position of the two second side plates 120 within the two first side plates 103 is adjusted using the adjusting assembly. Simultaneously, the adjusting assembly also moves the extension plate 106 into the extrusion plate 105. After adjusting the mold to the appropriate position, concrete is added to the mold. The electric push rod 104 is activated to move the extrusion plate 105 downwards, extruding the concrete. After the blocks solidify, the extrusion plate 105 is controlled to move upwards. After resetting, the drive unit inside the base 101 is activated again. The drive unit drives the first bidirectional lead screw 107 to rotate inside the base 101. Since the two sleeves 108 are threadedly engaged with the first bidirectional lead screw 107, the two sleeves 108 will move relative to each other on the first bidirectional lead screw 107. The two connecting rods 109 will push the top plate 110 upward. Subsequently, the top plate 110 will push the block out of the mold. By adopting the above method, the block can be conveniently pushed out of the mold, which is very convenient to use.

[0021] Furthermore, the drive unit includes a first motor 112, a first bevel gear 113, and a second bevel gear 114. The first motor 112 is fixedly connected to the base 101 and located inside the base 101. The first bevel gear 113 is fixedly connected to the output end of the first motor 112. The second bevel gear 114 is fixedly connected to the first bidirectional lead screw 107 and sleeved in the middle of the first bidirectional lead screw 107. The second bevel gear 114 meshes with the first bevel gear 113.

[0022] In this embodiment, when in use, the first motor 112 is started, and the first motor 112 controls the first bevel gear 113 to rotate. Since the first bevel gear 113 meshes with the second bevel gear 114, the rotation of the second bevel gear 114 will drive the first bidirectional lead screw 107 to rotate within the base 101.

[0023] Furthermore, the feeding assembly also includes a maintenance plate 115 and a fixing member. The maintenance plate 115 is located on the outside of the base 101, and the fixing member is connected to the maintenance plate 115 and the base 101 respectively. The fixing member includes two first magnetic blocks 116 and two second magnetic blocks 117. The two first magnetic blocks 116 are fixedly connected to the base 101 and are embedded in the outside of the base 101. The two second magnetic blocks 117 are fixedly connected to the maintenance plate 115 and are embedded in the inside of the maintenance plate 115. Each second magnetic block 117 is magnetically attracted to the first magnetic block 116.

[0024] In this embodiment, by providing the inspection plate 115 on the outside of the base 101, the components inside the base 101 can be protected and prevented from being exposed. The inspection plate 115 is fixed to the base 101 by the magnetic attraction between the second magnetic block 117 and the first magnetic block 116, which is simple to operate and convenient for later disassembly.

[0025] Furthermore, the adjustment assembly includes two fastening bolts 118, a second bidirectional lead screw 121, a guide rod 122, and a second motor 123. The second motor 123 is fixedly disposed on the outside of the bracket 102. The second bidirectional lead screw 121 is rotatably disposed inside the bracket 102 and connected to the output end of the second motor 123. The guide rod 122 is fixedly disposed inside the bracket 102. Two second side plates 120 are respectively sleeved on the outside of the second bidirectional lead screw 121 and the guide rod 122, and are threadedly engaged with the second bidirectional lead screw 121. Each extension plate 106 has multiple adjustment holes 119. Each fastening bolt 118 movably passes through the extrusion plate 105 and is connected to multiple adjustment holes 119.

[0026] In this embodiment, by starting the second motor 123, the motor drives the second bidirectional lead screw 121 to rotate. The second bidirectional lead screw 121 drives the two second side plates 120 to move closer to each other, adjusting the mold to a suitable position. The rotation of the second bidirectional lead screw 121 drives the extension plate 106 to move into the extrusion plate 105 and adjust it to a suitable position. The fastening bolt 118 is inserted into the adjustment hole 119 and tightened to adjust the size of the mold. The above is the prior art and will not be described in detail here.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
