Abstract
Description
Technical Field
[0001] This utility model relates to the field of building component forming equipment technology, and in particular to a precast concrete forming mold. Background Technology
[0002] Precast concrete components are widely used in modern construction, water conservancy, municipal, and transportation engineering projects, offering advantages such as short construction cycles, stable quality, and reusability. Specialized concrete molding molds play a crucial role in ensuring the quality and efficiency of precast component molding. With the increasing industrialization of construction, higher demands are placed on the molding precision, ease of operation, and adaptability of molds, especially in improving production efficiency and reducing manual labor, posing new challenges to mold structure design.
[0003] Currently, the widely used precast concrete molds are mainly made of steel plates, assembled into closed or semi-closed structures by welding or bolting. During use, concrete is poured into the mold, vibrated to compact it, and cured to a certain strength. Then, using hoisting equipment or manually, the connecting parts are loosened sequentially to complete the demolding operation. This type of mold has a relatively simple structure, is suitable for mass production, and has low manufacturing costs, making it widely used in the production of small and medium-sized precast components.
[0004] However, existing mold structures mostly use bolt fastening for assembly and disassembly, resulting in a cumbersome demolding process. Especially after the concrete has hardened, the mold often requires loosening each bolt individually or hoisting the entire mold, significantly increasing labor intensity and operation time, thus hindering production efficiency. Furthermore, when changing molds for precast components of different sizes, structural adjustments are inconvenient, leading to poor versatility. This problem severely restricts the flexible and large-scale development of precast concrete production. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a precast concrete molding mold, which aims to improve the problem that existing mold structures mostly use bolt fastening or welding methods, resulting in a cumbersome and difficult demolding process.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a precast concrete molding mold, comprising a base, a support plate fixedly connected to the upper surface of the base, a side plate fixedly connected to the upper surface of the support plate, a surrounding plate fixedly connected to the outer wall of the side plate, a sealing plate fixedly connected to the outer wall of the surrounding plate, and a quick-release assembly provided on the outer wall of the sealing plate.
[0007] The quick-release assembly includes a pin, which is disposed on one side of the outer wall of a sealing plate. A fixing block is fixedly connected to the outer wall of the sealing plate.

[0014] Furthermore, the outer wall of the second fixing block is fixedly connected to the outer wall of the first sealing plate.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by pressing the button, the button moves the pin forward via the connecting rod one. With the help of the elastic force of the spring two, the pin quickly embeds into the internal hole of the fixing block three, realizing the quick locking and fixing of the sealing plate. When it is necessary to disassemble or disconnect, simply press the push rod inside the fixing block one, which squeezes the spring one and pushes the connecting rod one backward.

Pin 25 is mainly used to insert into the interior of fixing block 27 and fix it.
[0028] Reference Figures 1-5The outer wall of the enclosure 5 is fixedly connected to a fixing frame 6. The fixing frame 6 is a reinforcing rib structure, mainly used to prevent the mold from deforming due to vibration or concrete lateral pressure.

[0029] Working principle: When a precast concrete component molding mold is needed, the bottom mold, side plate 3, surrounding plate 5, and corner mold 4 must first be assembled. Then, concrete is poured evenly into its interior, and sealing plate 7 and sealing plate 8 are sealed and fixed. The mold needs to ensure a tight seal at the component boundaries and easy demolding. To solve the problems of cumbersome and inefficient disassembly of traditional molds, this mold is equipped with a quick-release component. The quick-release component includes a pin 25 set on the outer wall of sealing plate 7. The pin 25 is connected to the button via connecting rod 23 and spring 26 inside. Button 20 is connected to the connecting rod 23, which drives the pin 25 to move in and out. When in use, pressing button 20 drives the connecting rod 23 to push the pin 25. Due to the action of spring 26, the pin enters the interior of fixing block 3 27. When it is necessary to disassemble and exit the fixed state, press the push rod 16 inside fixing block 15 to squeeze spring 22, and then quickly pull out connecting rod 23 to achieve automatic reset, thereby quickly releasing the connection between sealing plate 1 7 and sealing plate 2 8, improving demolding efficiency and avoiding disassembly difficulties caused by traditional bolts or welding structures.
[0030] In addition, to ensure the positioning accuracy of the wall and the overall stability of the mold during the concrete pouring process, the mold is equipped with a multi-segment adjustable support structure on the outside of the surrounding plate 5. The support structure consists of support rod 3 13, support rod 2 12 and support rod 1 11, which are connected to each other to form a multi-segment telescopic structure. The diagonal brace 19 is connected to the connecting rod 2 28 to strengthen the lateral support strength. By adjusting the length of the support rod and the angle of the diagonal brace, the mold surrounding plate 5 can be stably limited and supported to prevent deformation and displacement during the pouring process, ensure the accuracy of the boundary dimensions of the formed component, and also adapt to molds of different sizes for support, which is convenient for later demolding and reuse.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
