Description

Technical Field

[0001] This utility model relates to the field of foamed concrete technology, specifically a mold for demolding foamed concrete blocks. Background Technology

[0002] Foamed concrete blocks, also known as building blocks, are porous, lightweight materials made from cementitious materials such as cement, fly ash, and silica fume. They are produced through a physical foaming process that introduces numerous uniform, closed pores, followed by mixing, pouring, and curing. They are widely used in building energy conservation, civil engineering, and municipal infill projects.

[0003] Patent CN221736524U relates to the field of concrete mold technology and discloses a multi-layer mortise and tenon structure foam concrete mold, comprising: a multi-layer mold, wherein each multi-layer mold has a fixing ring on its outer perimeter, and the fixing ring is fixedly connected to the multi-layer mold; and an impact structure disposed outside the fixing rings, the impact structure comprising a fixing shell and a fixing plate. This utility model adds an impact structure to the outside of the mortise and tenon structure, causing the mortise to be loosened, thus facilitating the separation of the mortise and tenon structure.

[0004] In the production of foamed concrete, molds are needed to shape the foamed concrete. Although the molds in the aforementioned patents are convenient to assemble and separate, the edges and corners of the foamed concrete blocks tend to stick to the mold when they are demolded, causing damage to the edges and corners, resulting in damage to the foamed concrete blocks, reducing the production efficiency of foamed concrete blocks, and affecting the yield of foamed concrete blocks. To address these issues, we provide a demoldable foamed concrete block mold. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a demoldable foam concrete block mold. The soft side plate is detached from the block by a traction device linked to a lifting device, while the base is separated from the block by hammering vibration, thus avoiding sticking to the mold, reducing block damage, and improving yield and production efficiency.

[0006] To achieve its technical objectives, this utility model adopts the following technical solution:

Furthermore, unless otherwise specified, all components used in this application are commercially available components, and the connection between different components can be achieved through conventional technical means.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] This invention provides a demoldable foamed concrete block mold.

[0032] like Figure 1 As shown, the system includes a fixed base 1, a mold base 2, and a block frame. A lifting device for raising the mold base 2 and a vibration device for hammering the mold base 2 are installed between the mold base 2 and the fixed base 1. The block frame includes four flexible side plates 3 connected end to end. The block frame is positioned above the mold base 2 with flush edges. The block frame and the mold base 2 together form a cavity without a top cover. The flexible side plates 3 are made of composite materials, such as polyester fiber or sheet metal, which have elastic deformation. The mold base 2 and the flexible side plates 3 are combined to form a block mold. In actual production, foamed concrete raw materials are fed into the mold to produce foamed concrete blocks.

[0033] like Figure 2 As shown, four edges of the upper surface of the fixed base 1 are vertically provided with fixed frames 501. Roller assemblies and traction ropes 504 are provided on the fixed frames 501. One end of the traction rope 504 is fixedly connected to the upper end of the soft side plate 3, and the other end passes around the outside of the roller assembly and is fixedly connected to the mold base 2 through the buffer assembly.

[0034] As a preferred option, such as Figure 3 As shown, a motor and a horizontally arranged power bevel gear 605 are installed at the center of the bottom surface of the mold base 2 through a receiving cavity. The rotating shaft of the motor and the bottom of the power bevel gear 605 are fixedly connected. The power bevel gear 605 rotates horizontally under the drive of the motor. The motor and the power bevel gear 605 can serve as the power source for the lifting device and the vibration device.

[0035] As a preferred option, such as Figure 4As shown, the vibration device includes a hammer head 606 and a vibrating block 607. Specifically, the hammer head 606 includes an inner column 608 and an outer column 609 that are parallel to each other and vertically arranged. The outer column 609 is fixedly connected to the inner column 608 through an intermediate plate 610. The inner column 608 is vertically fixedly installed at the center of the upper surface of the power bevel gear 605, and the outer column 609 rotates around the inner column 608 under the drive of the motor. Specifically, the vibrating block 607 is accommodated in the receiving cavity, and the upper end of the vibrating block 607 is vertically fixedly connected to the mold base 2 through an elastic column 611. 607 is located in the rotation path of the outer column 609 of the hammer head 606. Driven by the motor, the power bevel gear 605 and the hammer head 606 rotate. During the rotation, the outer column 609 will hit the edge of the vibrating block 607. The vibrating block 607 generates vibration and transmits the vibration to the mold base 2, causing the mold base 2 to vibrate and separate the mold base 2 from the foam concrete block, avoiding the phenomenon of foam concrete block sticking to the mold and improving the yield of foam concrete block production. At the same time, under the action of the elastic column 611, the outer column 609 will not stop after hitting the vibrating block 607.

[0036] As a preferred option, such as Figure 3 and Figure 5 As shown, the lifting device includes a slider 602, threaded rods 603, and a lifting plate 601. Four threaded rods 603 are movably installed below the mold base 2. The threaded rods 603 can rotate on their own, but their relative position to the mold base 2 remains unchanged. The threaded rods 603 are arranged diagonally below the mold base 2 and pass through the slider 602 and are threadedly connected to the slider 602. One end of the threaded rod 603 is fixedly provided with a driven cone gear that meshes with the power bevel gear 605. The gear 604 is inserted into the bearing at one end. The bearing is vertically fixed to the lower wall of the mold base 2 by a bracket. Two threaded rods 603 are provided on the diagonal of each mold base 2. The end of the threaded rod 603 with the gear is pointed to the center of the mold base 2, and each pair of threaded rods 603 is symmetrical to each other. The top of the slider 602 is slidably connected to the bottom surface of the mold base 2. One end of the lifting plate 601 is hinged to the bottom end of the slider 602, and the other end is rotatably connected (hinged) to the upper surface of the fixed base 1.

[0037] In actual production or use, gears and brackets can be replaced with other components as needed, as long as the relative position of threaded rod 603 remains unchanged and it rotates in a fixed position.

[0038] When the motor drives the power bevel gear 605 to rotate, the driven bevel gear 604 rotates, which in turn causes the threaded rod 603 to rotate. Since the threaded rod 603 as a whole does not move but only rotates in a fixed position, the slider 602 gradually moves outward along the threaded rod 603 under the action of the threaded rod 603 (moving from the center position of the mold base 2 along the diagonal to the corner). Since the overall length of the lifting plate 601 remains unchanged, along with the movement of the slider 602, the upper end of the lifting plate 601 rotates clockwise and moves synchronously with the slider 602, while the lower end rotates counterclockwise. The lower end of the lifting plate 601 applies a thrust to the fixed base 1. Under the reaction of the fixed base 1, the mold base 2 is supported, thereby realizing the lifting and lowering of the mold base 2.

[0039] Sealing strips 4 can be detachably installed at the inner joint of adjacent soft side plates 3, and the surface of the sealing strip 4 abuts against the adjacent soft side plates 3. The sealing strip 4 seals the joint of the two soft side plates 3, preventing the slurry from flowing out and improving the production efficiency of foamed concrete blocks.

[0040] As a preferred option, such as Figure 2 As shown, the roller assembly includes an upper support wheel 503 and a lower support wheel 502 that are rotatably mounted on the upper and lower ends of the fixed frame 501, respectively. One end of the traction rope 504 is fixedly connected to the inner side of the fixed frame 501 and the upper end of the soft side plate 3, and the other end passes around the outer side of the upper support wheel 503 and the lower support wheel 502 and is fixedly connected to the inner side of the fixed frame 501 and the mold base 2.

[0041] Preferably, the buffer assembly is a buffer spring 505, with one end of the traction rope 504 fixedly connected to the buffer spring 505, and the other end of the buffer spring 505 fixedly connected to the mold base 2. The buffer spring 505 provides buffering for the traction rope 504, making the traction rope 504 pull the soft side plate 3 more smoothly, avoiding damage to the foam concrete block caused by strong pulling, reducing damage to the foam concrete block, and improving the yield rate of foam concrete block production.

[0042] Preferably, the four outer corners of the block frame are provided with corner plates 507. Two mutually perpendicular connecting plates 506 are fixedly installed on the surface of the corner plate 507 perpendicular to its own length direction. The connecting plates 506 are fixedly connected to the side wall of the fixing frame 501. The corner plates 507 are fixed by the connecting plates 506, thereby improving the stability of the corner plate 507 in positioning the soft side plate 3.

[0043] Working principle: The block mold is formed by combining the mold base 2 and the block frame. Foamed concrete raw materials are fed into the mold to produce foamed concrete blocks. After the foamed concrete blocks are formed, the motor controls the rotation of the power bevel gear 605. The power bevel gear 605 drives the hammer head 606 to rotate and strike the vibrating block 607, causing the mold base 2 to vibrate and separate the mold base 2 from the foamed concrete blocks. At the same time, the rotation of the power bevel gear 605 controls the rotation of the driven bevel gear 604, which drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 causes the slider 602 to move one end of the lifting plate 601, which in turn moves the mold base 2 upward. When the mold base 2 moves upward, the traction rope 504 pulls the soft side plate 3, flipping the top of the soft side plate 3 outward and slowly pulling the soft side plate 3 off the surface of the foamed concrete block, reducing damage to the foamed concrete block and improving the yield of foamed concrete blocks.

[0044] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
