Description

Technical Field

[0001] This utility model belongs to the field of building material production technology, and in particular relates to a mold for preparing high earthquake-resistant autoclaved aerated concrete blocks. Background Technology

[0002] With the continuous development of the construction industry and building materials, various new materials have emerged. Among them, high seismic-resistant autoclaved aerated concrete (AAC) blocks are a type of AAC blocks specifically designed to improve the seismic performance of buildings. They inherit many advantages of ordinary AAC blocks (such as lightweight, heat insulation, fire resistance, sound insulation, and environmental protection), and significantly improve their performance under earthquake loads through material formula optimization, production process control, structural design enhancement, and standardized construction methods. In the production process of high seismic-resistant AAC blocks, the concrete blocks are poured and prepared using special molds, which can improve the efficiency and quality of concrete block preparation.

[0003] A search revealed that publication number CN222987186U, application date 2024.09.03, discloses a mold for autoclaved aerated concrete (AAC) blocks, comprising: a workbench, a limiting seat embedded in the top of the workbench, a placement component for holding AAC blocks on the upper end of the limiting seat, an extrusion component for extruding and molding the AAC blocks on the upper end of the placement component, several pillars fixedly connected to both sides of the top of the workbench, and a support plate fixedly connected to the top of the pillars, the placement component including a placement frame disposed on the top of the limiting seat, several I-shaped locking seats engaged inside the placement frame, and first locking blocks engaged at both ends of the inner walls of the I-shaped locking seats, each first locking block being fixedly connected to the inner wall of the placement frame, thereby shortening the production time of AAC blocks and improving production efficiency.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing high seismic-resistant autoclaved aerated concrete block preparation molds require manual disassembly and placement of components during mold removal, which affects the efficiency of concrete block removal and increases workload;

[0006] 2. Existing high-seismic-resistance autoclaved aerated concrete (AAC) block preparation molds use extrusion components to compact the grout. However, this method easily leads to air bubbles in the grout during injection, affecting product quality. Therefore, we provide a high-seismic-resistance AAC block preparation mold to solve the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a mold for preparing high-seismic-resistant autoclaved aerated concrete (AAC) blocks. By setting a top plate of the top mold assembly to lift the high-seismic-resistant AAC blocks out of the mold box, the demolding and feeding efficiency of the high-seismic-resistant AAC blocks can be accelerated. Furthermore, by using a striking assembly to drive multiple rotating plates and striking rods to rotate around a pivot axis, and under the elastic action of torsion springs, the striking rods continuously strike the mold box, ensuring that the slurry can be evenly filled into the mold box, reducing air bubbles in the slurry, and improving product quality.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a mold for preparing high earthquake-resistant autoclaved aerated concrete blocks, including a processing table and a rotating groove set at the rear end of its upper surface. A top mold assembly is set at the bottom of the processing table, and a hammering assembly is set inside the rotating groove.

[0010] The top mold assembly includes a hanger mounted on the bottom of the processing table and a first motor mounted on one side wall of the hanger, with a drive sprocket mounted on the output shaft of the first motor;

[0011] The striking assembly includes a second motor mounted at the rear end of the bottom of the processing table, and a drive gear mounted on the output shaft of the second motor, with a driven gear meshing directly above the drive gear.

[0012] The present invention is further configured such that a mounting frame is installed on the upper surface of the processing table, an extrusion seat is slidably installed inside the mounting frame, and a lifting component is provided on the outer side of the extrusion seat.

[0013] The present invention is further configured such that a mold box is installed at the center of the upper surface of the processing table, and side plates are installed on both sides of the mold box.

[0014] The present invention is further configured such that partitions are evenly spaced along the horizontal direction inside the mold box, and top plates are evenly spaced along the horizontal direction at the bottom of the mold box.

[0015] The present invention is further configured such that a chain is fitted on the outer wall of the driving sprocket, and driven sprockets are evenly spaced along the horizontal direction inside the chain, with a screw fixed at the top center of the driven sprocket.

[0016] The present invention is further configured such that the top end of the screw passes through the bearing on the hanger and is threadedly connected to the threaded groove at the bottom of the lifting cylinder, and the top end of the lifting cylinder passes through the sliding hole at the bottom of the processing table and the mold box and is connected to the top plate.

[0017] The present invention is further configured such that a rotating shaft is fixedly provided at the center of the inner wall of the driven gear disk, and the two ends of the rotating shaft are rotatably mounted in bearings on the inner wall of the rotating groove.

[0018] The present invention is further configured such that torsion springs are fitted at both ends of the outer wall of the rotating shaft, rotating plates are fitted at even intervals along the horizontal direction on the outer wall of the rotating shaft, and a striking rod is fixed to the top of the front end face of the rotating plate.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a top mold assembly, allows the operation of a first motor to push the lifting cylinder upward, thereby lifting the top plate to eject the high-seismic-resistant autoclaved aerated concrete blocks from the mold box. This accelerates the demolding and feeding efficiency of the high-seismic-resistant autoclaved aerated concrete blocks, solving the problem that existing high-seismic-resistant autoclaved aerated concrete block preparation molds require manual disassembly and placement of components during demolding, which affects the demolding efficiency of concrete blocks and increases the workload.

[0021] 2. This utility model, by setting up a striking component, allows the second motor to drive multiple rotating plates and striking rods to rotate around a pivot axis. Under the elastic action of the torsion spring, the striking rods continuously strike the mold box, ensuring that the slurry can be evenly filled into the mold box, reducing air bubbles in the slurry, improving product quality, and solving the problem that existing high seismic-resistant autoclaved aerated concrete block preparation molds use an extrusion component to compact the slurry, which easily leads to air bubbles in the slurry during injection, affecting product quality.

Detailed Implementation

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1 to 5 This utility model is a mold for preparing high earthquake-resistant autoclaved aerated concrete blocks, including a processing table 100 and a rotating groove 103 disposed at the rear end of its upper surface. A top mold assembly 200 is disposed at the bottom of the processing table 100. The top mold assembly 200 includes a hanger 201 installed at the bottom of the processing table 100 and a first motor 202 installed on one side wall of the hanger 201. A drive sprocket 202a is installed on the output shaft of the first motor 202.

[0034] Specifically, a mounting bracket 101 is installed on the upper surface of the processing table 100, and an extrusion seat 102 is slidably installed inside the mounting bracket 101. A lifting assembly 102a is provided on the outer side of the extrusion seat 102. A mold box 104 is installed at the center of the upper surface of the processing table 100, and side plates 104a are installed on both side walls of the mold box 104. Partitions 104b are evenly spaced along the horizontal direction inside the mold box 104, and partitions 104b are evenly spaced along the horizontal direction at the bottom of the mold box 104. A top plate 105 is embedded therein; a chain 203 is sleeved on the outer wall of the drive sprocket 202a, and driven sprockets 204a are evenly spaced in the horizontal direction inside the chain 203. A screw 204 is fixed at the top center of the driven sprocket 204a; the top end of the screw 204 passes through the bearing on the hanger 201 and is threadedly connected to the threaded groove at the bottom of the lifting cylinder 205. The top end of the lifting cylinder 205 passes through the sliding hole at the bottom of the processing table 100 and the mold box 104 in sequence and is connected to the top plate 105.

[0035] Furthermore, the extrusion seat 102, lifting assembly 102a, mold box 104, etc. are all existing technologies, so they will not be described in detail here. Under the action of the chain 203, the driving sprocket 202a and multiple driven sprockets 204a are connected to achieve the transmission function. The external thread on the outer wall of the screw 204 is threadedly connected to the threaded groove at the bottom of the lifting cylinder 205. The lifting cylinder 205 is slidably installed in the sliding hole on the processing table 100. The lifting cylinder 205 is rectangular, which can limit and guide the lifting cylinder 205, and prevent the lifting cylinder 205 from rotating when the screw 204 rotates.

[0036] The operation process of this embodiment is as follows: After the slurry is injected, the extrusion seat 102 is pushed down by the lifting component 102a, so that the extrusion seat 102 presses into the mold box 104 and compacts the slurry. After standing still for a period of time under suitable temperature and humidity, the blank body gains initial strength. When demolding is required, the first motor 202 is started. The output shaft of the first motor 202 rotates, driving the drive sprocket 202a to rotate. The outer wall of the drive sprocket 202a is connected to multiple driven sprockets 204a through the chain 203. Therefore, the drive sprocket 202a... When the screw 204 rotates, it will drive multiple driven sprockets 204a to rotate synchronously under the action of the chain 203. The rotation of the driven sprockets 204a will drive the screw 204 to rotate. The external thread on the outer wall of the screw 204 is threadedly connected to the threaded groove at the bottom of the lifting cylinder 205. Therefore, when the screw 204 rotates, it will push the lifting cylinder 205 to rise. As the lifting cylinder 205 rises, it will push the top plate 105 to rise, thereby ejecting the high seismic-resistant autoclaved aerated concrete blocks in the mold box 104. This can speed up the demolding and feeding efficiency of the high seismic-resistant autoclaved aerated concrete blocks.

[0037] Example 2

[0038] Please see Figure 3 and Figure 6 Based on Embodiment 1, unlike the first embodiment, a striking component 300 is provided. The striking component 300 includes a second motor 301 installed at the rear end of the bottom of the processing table 100, and an active gear 302 installed on the output shaft of the second motor 301. A driven gear 303a is meshed directly above the active gear 302. This solves the problem that existing high seismic-resistant autoclaved aerated concrete block preparation molds use an extrusion component to compact the slurry, which can easily cause air bubbles in the slurry during injection, affecting product quality.

[0039] Specifically, a rotating shaft 303 is fixed at the center of the inner wall of the driven gear disk 303a, and both ends of the rotating shaft 303 are rotatably installed in bearings on the inner wall of the rotating groove 103; torsion springs 304 are sleeved on both ends of the outer wall of the rotating shaft 303, and rotating plates 305 are evenly spaced on the outer wall of the rotating shaft 303 in the horizontal direction, and a striking rod 305a is fixed on the top of the front end face of the rotating plate 305.

[0040] Furthermore, only a portion of the outer circumference of the active gear disk 302 is provided with a rack. The rack on the outer wall of the active gear disk 302 meshes with the rack on the outer wall of the driven gear disk 303a, thus playing a transmission role. Under the elastic action of the torsion spring 304, the rotating plate 305 and the striking rod 305a can rotate around the rotating shaft 303 as the axis.

[0041] The operation process of this embodiment is as follows: When producing high seismic-resistant autoclaved aerated concrete blocks, the side plates 104a, partition plates 104b, etc. are first assembled onto the mold box 104 in sequence. Then, the slurry is injected into the mold box 104. Next, the second motor 301 is started. The output shaft of the second motor 301 rotates, driving the active gear disk 302 to rotate. Only a portion of the outer wall of the active gear disk 302 is provided with racks, and the racks on the outer wall of the active gear disk 302 mesh with the racks on the outer wall of the driven gear disk 303a. Therefore, when the active gear disk 302 rotates... When rotating, it drives the driven gear plate 303a to perform a cyclic reciprocating motion. The rotation of the driven gear plate 303a drives the rotating shaft 303 to rotate synchronously and compress the torsion spring 304. Under the elastic performance of the torsion spring 304 and the intermittent meshing action of the driving gear plate 302 and the driven gear plate 303a, the rotating plate 305 and the striking rod 305a oscillate back and forth around the rotating shaft 303. Thus, after the slurry is injected, it can continuously strike the mold box 104, so that the slurry can be spread evenly in the mold box 104, reducing air bubbles in the slurry and improving product quality.
