Description

Technical Field

[0001] This utility model relates to the field of precast wall panel technology, and in particular to a precast wall panel demolding mold. Background Technology

[0002] Precast slabs, commonly used modules or panels in construction engineering, are produced through a process that primarily involves creating a hollow model in a prefabrication yard using wooden boards, then arranging reinforcing bars in the hollow part of the model and filling it with cement. After drying, the wooden boards are removed to form the precast slab. The structure of such precast slabs is typically a fixed ring-shaped frame structure, as shown in the precast slab mold and its demolding device disclosed in Chinese Patent Publication No. CN112720805B.

[0003] However, existing precast panel production technology has certain defects in the process of lifting and demolding the mold. Specifically, because the mold and the cast wall panel are tightly fitted together, when the mold moves upward, it will scratch the edges and corners of the precast wall panel. Especially at the corners, it is very easy to cause corner chipping. This not only affects the aesthetics of the precast panel, but may also affect its structural strength and service life.

[0004] Based on this, in order to further improve the stability of demolding of existing molds, we propose a demolding mold for prefabricated wall panels. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the scraping of the edges and corners of the precast wall panel when the mold moves upward due to the tight fit between the mold and the cast wall panel. Therefore, a precast wall panel demolding mold is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Design a precast wall panel demolding mold, comprising a rectangular frame consisting of two first mold frames and two second mold frames, wherein the ends of the first mold frames and the second mold frames are connected by a fastening mechanism;

[0008] The fastening mechanism includes a rod that passes through the first mold frame, a portion of which is located outside the second mold frame and slidably connected to the second mold frame. On both sides of the rod are respectively provided a stop member for stopping the first mold frame and a drive member for abutting the second mold frame. The drive member is used to move the second mold frame toward the side of the first mold frame.

[0009] Furthermore, the rod is a U-shaped rod, with the middle part of the U-shaped rod located outside the second mold frame. Two slide rails for sliding at both ends of the U-shaped rod are also provided on the end face of the second mold frame.

[0010] Furthermore, the stop component includes a nut threadedly connected to the end of the rod, and a rubber sleeve is fitted on the outside of the rod, the rubber sleeve being located between the nut and the side of the first mold frame.

[0011] Furthermore, the driving component is an eccentrically rotating disc handle located in the middle of the U-shaped rod.

[0012] Furthermore, a positioning post is fixedly installed on the side of the first mold frame, and a positioning hole adapted to the positioning post is opened on the end face of the second mold frame, wherein the outer side of the disc handle has a clearance opening to avoid the positioning post.

[0013] Furthermore, a sleeve is fixedly installed on the inner side of the first mold frame, and a top column is movably connected to the inner side of the sleeve via a compression spring. The end of the top column passes through the first mold frame and abuts against the side of the second mold frame.

[0014] The present invention provides a precast wall panel demolding mold with the following advantages: By employing a design where the first and second mold frames are separable from each other, after pouring, the fastening mechanism can be opened to sequentially separate the second and first mold frames from the sides of the precast wall panel. This separates the joint between the first and second mold frames from the corners of the precast wall panel. When the mold is subsequently lifted by a lifting device, the gap between the mold and the precast wall panel prevents any scraping of the corners or sides, greatly improving the overall aesthetics and corner integrity of the precast wall panel.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 As one embodiment of this utility model, a precast wall panel demolding mold is disclosed. The mold includes a rectangular frame composed of two first mold frames 1 and two second mold frames 2. Of course, in order to facilitate the lifting of the rectangular frame, lifting lugs can also be provided on both sides of the second mold frames 2 to facilitate connection with lifting equipment. The ends of the first mold frames 1 and the second mold frames 2 are connected by a fastening mechanism 3.

[0021] The fastening mechanism 3 includes a rod 31 that passes through the first mold frame 1. A portion of the rod 31 is located outside the second mold frame 2 and is slidably connected to the second mold frame 2. A stop member 32 for stopping the first mold frame 1 and a drive member 33 for abutting the second mold frame 2 are respectively provided on both sides of the rod 31. The drive member 33 is used to abut the second mold frame 2 and move towards the side of the first mold frame 1.

[0022] In some embodiments, the rod 31 in this invention is a U-shaped rod, the middle part of which is located outside the second mold frame 2. The middle part is the bent portion of the middle part of the U-shaped rod. Two slide rails 21 are also provided on the end face of the second mold frame 2 for sliding at both ends of the U-shaped rod. The two slide rails 21 are horizontally arranged so that when the first mold frame 1 and the second mold frame 2 are released, the two ends of the first mold frame 1 can slide back and forth between two adjacent second mold frames 2 by means of the design of the slide rails 21, so as to realize the side separation of the formed precast wall panel.

[0023] Based on the above embodiments, the stop component 32 in this embodiment includes a nut 321 threadedly connected to the end of the rod 31, and a rubber sleeve 322 sleeved on the outside of the rod 31. The rubber sleeve 322 is designed to provide elastic force to ensure the stability of subsequent clamping actions. In this embodiment, the rubber sleeve 322 can be set as a silicone sleeve. The position of the rubber sleeve 322 can be changed by the nut 321 to adjust the resistance force. The rubber sleeve 322 is located between the nut 321 and the side of the first mold frame 1.

[0024] Furthermore, in this embodiment, the driving component 33 is an eccentrically rotating disc handle located in the middle of the U-shaped rod. The disc handle includes a disc portion and a handle portion. The disc portion rotates eccentrically with the middle of the U-shaped rod. Thus, when the entire disc handle rotates, a cam motion structure is formed, which moves the second mold frame 2 against the first mold frame 1 towards one side until the rubber sleeve 322 at the end of the U-shaped frame tightly abuts against the nut 321 and the first mold frame 1. Due to the limiting effect of the nut 321, a tight connection is maintained between the first mold frame 1 and the second mold frame 2.

[0025] It should be noted that, in order to ensure the alignment accuracy of the first mold frame 1 and the second mold frame 2 in their initial positions, a positioning post 11 is fixedly installed on the side of the first mold frame 1 in this embodiment. A positioning hole 22 adapted to the positioning post 11 is opened on the end face of the second mold frame 2. The outer side of the disc handle has a clearance opening 331 to avoid the positioning post 11. That is to say, by adopting the design of positioning post 11 and positioning hole 22 in this embodiment, when assembling the entire mold, the positioning post 11 can be aligned and snapped with the positioning hole 22 to ensure the connection accuracy of its initial position and avoid misalignment affecting installation and other problems. The clearance opening 331 is used to avoid the positioning post 11 when the disc handle rotates, so as to avoid the problem of mutual interference between the two movements.

[0026] It should be noted that, in order to push the second mold frame 2 outward during demolding, a sleeve 12 is fixedly installed on the inner side of the first mold frame 1. The inner side of the sleeve 12 is movably connected to the top column 14 through the compression spring 13. The end of the top column 14 passes through the first mold frame 1 and abuts against the side of the second mold frame 2. In this embodiment, by adopting the design of the compression spring 13 and the top column 14, when the disc handle is rotated during demolding, the fastening force between the first mold frame 1 and the second mold frame 2 disappears. At the same time, under the abutment of the top column 14, the second mold frame 2 can be moved outward to quickly form a gap with the first mold frame 1. At the same time, the positioning column 11 separates from the positioning hole 22, and the first mold frame 1 can slide back and forth through the U-shaped frame. Since the first mold frame 1 and the second mold frame 2 are separated from the precast wall panel at this time, the corners of the precast wall panel will not be scratched during lifting, thus greatly ensuring the appearance consistency of the precast wall panel during demolding.

[0027] In summary, this utility model employs a design where the first mold frame 1 and the second mold frame 2 can be separated from each other. After pouring, by opening the fastening mechanism 3, the second mold frame 2 and the first mold frame 1 can be separated from the side of the precast wall panel in sequence. This separates the joint between the first mold frame 1 and the second mold frame 2 from the corner of the precast wall panel. When the mold is subsequently lifted by a lifting device, the gap between the mold and the precast wall panel prevents any scraping of the corners and sides of the precast wall panel, greatly improving the overall aesthetics of the precast wall panel and the integrity of the corners.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
