Description

Technical Field

[0001] The utility model relates to the technical field of aerated concrete block blank demoulding devices, in particular to a blank edge material self-removing mold. Background Art

[0002] Aerated concrete blocks are a new type of building material that is lightweight, porous, heat-insulating, seismic-insulating, sound-insulating, energy-saving, and environmentally friendly. They are made of cement, lime, silica sand, etc. as the main raw materials, mixed with aluminum powder as an aerating agent, and are made into porous concrete products through processes such as grinding, metering, mixing and pouring, gas expansion, static maintenance, and cutting. Because they have a large number of pores and micropores inside, they have excellent thermal insulation properties, low thermal conductivity, and high thermal resistance. At the same time, aerated concrete blocks also have good seismic resistance, fire resistance, and sound insulation properties, which can effectively improve the overall performance of the building. Aerated concrete blocks are widely used in the construction of interior and exterior wall filling, partition walls, floor slabs and roof panels of various buildings. Compared with traditional solid clay bricks, aerated concrete blocks have lighter weight, higher strength, better thermal insulation and lower cost. Therefore, the use of aerated concrete blocks can effectively reduce the weight of the building, improve construction efficiency, reduce construction costs, and also help save energy and reduce emissions and protect the environment. The demoulding process of aerated concrete blanks is a delicate and critical production link. The blanks are ensured to be stable by fixing the mold-type mold or other demoulding and curing molds. Subsequently, the blanks are hoisted to the demoulding station by a crane, and the demoulding is carried out by special demoulding machines or manual methods to ensure standardized operation and avoid damage. Finally, the demoulding blanks are marked with necessary marks and production dates to complete the entire demoulding process. This link requires careful operation to ensure the quality and integrity of the blanks.

[0003] After the aerated concrete block slurry is added to the mold for hardening and curing, expansion will indeed occur. This expansion process is mainly due to the reaction between the aluminum powder in the aerated concrete block and the alkaline substance, releasing hydrogen, thereby expanding the volume of the concrete. If this part of the expansion exceeds the mold itself, the embryo after demolding will be asymmetrical on the left and right. When it is transported to the next step for peeling and cutting, it is very likely that the tool will be subjected to uneven force, causing cracks inside the embryo, resulting in cracks in the produced blocks. Utility Model Content

[0004] (I) Technical problems solved: In view of the deficiencies in the prior art, the utility model provides a self-removing mold for the blank edge material, which has the advantage of automatically removing the blank edge material during the demoulding process, and solves the problem of edge deformation caused by expansion during the hardening and curing of the aerated concrete slurry.

[0005] (ii) Technical solution: In order to achieve the purpose of automatically removing the blank edge material during the above-mentioned demolding process, the utility model provides the following technical solution: a blank edge material self-removal mold, including a mold body and a mold baffle, one side of the mold body is not provided with a baffle to form a notch, a connecting column is provided in the direction of the notch of the mold body, the mold baffle is connected to the connecting column by a buckle provided on the outside, so that the mold body and the mold baffle form a top-opening mold, clamping ends and cutting devices are provided at both ends of the mold body, a cutting rope is provided between the cutting devices at both ends, and a rotating motor is provided in the cutting device to drive the cutting rope to rotate, so as to cut the portion of the blank that exceeds the mold body.

[0006] Preferably, cutting guide rails are provided at both ends of the mold body, and the cutting device is arranged on the cutting guide rails and can be translated. By moving the cutting device on one side, the cutting rope forms an oblique line. The inclination helps to discharge the waste and debris generated in the peeling process along the inclined direction, reducing the accumulation that causes the uneven cutting surface during the cutting process.

[0007] Preferably, the baffles at both ends of the mold body extend 2-3 mm toward the notch to form an L-shaped structure, and a scraper is provided on the inner side of the extended part. In the subsequent peeling process of the blank, only the side or top surface of the blank is peeled, while the front and back sides of the blank are not peeled, so there may be uneven parts. By utilizing the upward pulling and demolding process of the mold, the front and back sides are peeled with a scraper to make the surface smoother.

[0008] Preferably, the surface of the cutting rope is provided with serrated protrusions, and these teeth can increase the contact area with the blank during rotation, thereby improving the cutting efficiency. The toothed cutting rope is suitable for occasions requiring higher cutting accuracy, and can more effectively cut hard blanks, making the cutting surface smoother and reducing the generation of cracks.

[0009] Preferably, the mold body and the inner side of the mold baffle are coated with a silicone oil release agent coating. The silicone oil release agent has excellent lubricating properties, which significantly reduces the friction between the aerated concrete and the mold during the demolding process, thereby ensuring smooth demolding. The silicone oil release agent has a small surface tension and can easily form a uniform film on the mold surface, covering all contact surfaces, ensuring the uniformity of the demolding effect. In addition, its easy dispersibility also makes the coating operation easier.

[0010] (III) Beneficial effects: Compared with the prior art, the utility model provides a blank edge material self-removal mold, which has the following beneficial effects:

[0011] 1. The blank edge material is removed from the mold by itself. The mold body is pulled up by the overhead crane to achieve demoulding. The mold baffle and the blank are placed on the transport rail and transported to the next step. During the process of the overhead crane pulling up, the cutting device works to drive the cutting rope to rotate, and the part of the upper end of the aerated concrete block that has expanded beyond the mold is cut. The cutting device is located above the mold. By driving the cutting rope to rotate, the aerated concrete block that exceeds the mold can be accurately cut. This design ensures the accuracy and consistency of cutting, avoids the errors that may occur during manual cutting, and thus ensures the accuracy of the block size. Accurate cutting can not only ensure the size of the block The accuracy of the size can also reduce the surface defects or damage of the blocks caused by improper cutting, which helps to improve the overall quality of the blocks, meet customer needs, and enhance the market competitiveness of the products. The automated cutting device can quickly complete the cutting task, reducing the time and labor costs of manual operation. At the same time, the edge of the blank is removed during the demoulding process by pulling the mold upward with the overhead crane. While the mold is pulled upward, the cutting rope removes the edge of the blank as the mold is pulled upward. When the mold is completely demoulded, the edge material is removed. The cutting device is combined with the demoulding process to realize the continuous operation of demoulding and cutting, further improving the overall efficiency of the production line.

[0012] 2. The blank edge material self-removal mold is provided with cutting guide rails at both ends of the mold body. The cutting device 12 is arranged on the cutting guide rails and can be translated. By moving the cutting device on one side, the cutting rope forms an oblique line. The inclination helps to discharge the waste and debris generated in the peeling process in the inclined direction, reducing the accumulation and causing the uneven cutting surface during the cutting process. The baffles at both ends of the mold body extend 2-3 mm to the notch to form an L-shaped structure. A scraper is provided on the inner side of the extended part. In the subsequent peeling process of the blank, only the side or top surface of the blank is peeled, and the front and back sides of the blank are not peeled, so there may be uneven parts. By utilizing the upward pulling and demoulding process of the mold, the front and back sides are peeled with a scraper to make the surface smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 2 The blank edge material self-removal mold comprises a mold body 1 and a mold baffle 2. One side of the mold body 1 is not provided with a baffle to form a notch. A connecting column 101 is provided in the notch direction of the mold body 1. The mold baffle 2 is connected to the connecting column 101 through a buckle 102 provided on the outside, so that the mold body 1 and the mold baffle 2 form a top-opening mold. Clamping ends 11 and cutting devices 12 are provided at both ends of the mold body 1. A cutting rope 122 is provided between the cutting devices 12 at both ends. A rotating motor is provided in the cutting device 12 to drive the cutting rope 122 to rotate, so as to cut the portion of the blank exceeding the mold body 1.

[0019] Furthermore, the worker uses the clamping device on the overhead crane to clamp the clamping ends 11 at both ends of the mold body 1, and rotates the mold as a whole so that one side of the mold baffle 2 faces downward, opens the buckle 102 on the mold baffle 2, separates the mold baffle 2 from the mold body 1, and uses the overhead crane to pull up the mold body 1 to achieve demolding, and places the mold baffle 2 and the blank on the transport rail for transportation to the next step. During the process of the overhead crane pulling up, the cutting device 12 works to drive the cutting rope 122 to rotate, and cuts the upper end of the aerated concrete block that has expanded beyond the mold. The cutting device is located above the mold, and by driving the cutting rope to rotate, it can accurately cut the aerated concrete block that exceeds the mold.

[0020] Cutting guide rails 121 are provided at both ends of the mold body 1. The cutting device 12 is arranged on the cutting guide rails 121 and can be translated. By moving the cutting device 12 on one side, the cutting rope 122 forms an oblique line. The inclination helps to discharge the waste and debris generated in the peeling process along the inclined direction, reducing the accumulation that causes the uneven cutting surface during the cutting process.

[0021] See also Figure 3The baffles at both ends of the mold body 1 extend 2-3 mm toward the notch to form an L-shaped structure. A scraper is provided on the inner side of the extended part. In the subsequent peeling process of the blank, only the side or top surface of the blank is peeled, while the front and back sides of the blank are not peeled, so there may be uneven parts. By utilizing the upward pulling and demoulding process of the mold, the front and back sides are peeled with a scraper to make the surface smoother.

[0022] The surface of the cutting rope 122 is provided with serrated protrusions, which can increase the contact area with the blank during rotation and improve the cutting efficiency. The toothed cutting rope 122 is suitable for occasions requiring higher cutting accuracy and can more effectively cut hard blanks, making the cutting surface smoother and reducing the generation of cracks.

[0023] The inner sides of the mold body 1 and the mold baffle 2 are coated with a silicone oil release agent coating. The silicone oil release agent has excellent lubricating properties, which significantly reduces the friction between the aerated concrete and the mold during the demolding process, thereby ensuring smooth demolding. The silicone oil release agent has a small surface tension and can easily form a uniform film on the mold surface, covering all contact surfaces, ensuring the uniformity of the demolding effect. In addition, its easy dispersibility also makes the coating operation easier.

[0024] Working principle: See Figure 2 , the worker uses the clamping device on the overhead crane to clamp the clamping ends 11 at both ends of the mold body 1, and rotates the mold as a whole so that one side of the mold baffle 2 faces downward, opens the buckle 102 on the mold baffle 2, separates the mold baffle 2 from the mold body 1, and uses the overhead crane to pull up the mold body 1 to achieve demoulding, and places the mold baffle 2 and the blank on the transport rail for transportation to the next step. After the aerated concrete block slurry is added to the mold for hardening and curing, it will indeed expand. This expansion process is mainly due to the reaction of aluminum powder in the aerated concrete block with alkaline substances to release hydrogen, thereby expanding the volume of the concrete. If this part of the expansion exceeds the mold itself, the left and right sides of the blank after demoulding will not be aligned. It is said that when the material is transported to the next step for peeling and cutting, it is very likely that the tool will be subjected to uneven force, causing cracks inside the embryo and resulting in cracks in the produced blocks. During the process of the overhead crane being pulled up, the cutting device 12 works to drive the cutting rope 122 to rotate, so as to cut the portion of the upper end of the aerated concrete block that has expanded beyond the mold. The cutting device is located above the mold, and because of the rotation of the overhead crane, the overhead crane can accurately cut the aerated concrete block that exceeds the mold by driving the cutting rope to rotate while pulling the mold upward to demould. This design ensures the accuracy and consistency of the cutting, avoids possible errors in manual cutting, and thus ensures the accuracy of the block size.
