Technical Field

[0001] The utility model specifically relates to the technical field of concrete moulds, in particular to a concrete rapid demoulding device. Background Art

[0002] Concrete is one of the most commonly used building materials in modern construction projects, and its quality is directly related to key performance factors such as a building's safety and durability. Concrete test blocks play an indispensable role in assessing concrete quality. By producing and testing concrete test blocks, various properties of concrete can be accurately evaluated before, during, and after construction, thereby ensuring project quality.

[0003] Traditional concrete molds present numerous challenges when it comes to demolding. Firstly, due to the strong adhesion between the concrete and the mold's inner walls, demolding is often difficult, requiring significant effort and time. For example, when demolding complex concrete components, traditional molds can damage the component's surface, impacting the quality and appearance of the concrete product. Secondly, traditional molds suffer from low demolding efficiency, which can severely impact project progress in large-scale concrete construction. Furthermore, frequent demolding operations can easily cause mold wear, reducing mold life and increasing construction costs. Utility Model Content

[0004] The purpose of the utility model is to provide a concrete rapid demoulding device, which can quickly form the concrete into concrete blocks by compressing it after loading it, and then lift the concrete blocks out by lifting and supporting them, thereby effectively improving the efficiency of concrete block demoulding and solving the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A concrete rapid demoulding device comprises a forming formwork, a top seat being slidably connected to the forming formwork; support plates being welded to the four corners of the bottom of the top seat via push rods; a U-shaped buckle being welded to the middle position of the top of the support plate, and a rotating shaft being movably connected to the U-shaped opening; both ends of the rotating shaft being movably connected to a movable frame, the movable frame being connected across both sides of the forming formwork, and a force-applying component capable of lifting the movable frame is provided below the movable frame;

[0010] As a further technical solution of the present invention, the force applying seat is L-shaped, and a clamping frame is movably connected to one end of the force applying seat close to the force applying arm; the clamping frame is buckled with an arc-shaped positioning block welded on the movable frame.

[0011] As a further technical solution of the present invention, one end of the top cover is movably connected to a movable shaft, and both ends of the movable shaft are rotatably connected to the bracket.

[0012] As a further technical solution of the present invention, the ribs are arranged in a trapezoidal shape, and a C-shaped groove is opened on the upper surface of the ribs to facilitate the positioning of the force-applying shaft.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 In an embodiment of the present invention, a rapid demoulding device for concrete includes a forming formwork 6, in which a top seat 14 is slidably connected; a support plate 4 is welded to the four corners of the bottom of the top seat 14 through a push rod 3; a U-shaped buckle is welded to the middle position of the top of the support plate 4, and a rotating shaft 5 is movably connected in the U-shaped mouth; both ends of the rotating shaft 5 are movably connected to a movable frame 11, which is connected across both sides of the forming formwork 6, and a force-applying component 10 capable of lifting the movable frame 11 is provided below the movable frame 11;

[0027] The force-applying assembly 10 is mounted in conjunction with the ribs 8; two ribs 8 are provided and welded to the top cover 7. The forming mold shell 6 is welded to the upper ends of the four brackets 2; and the lower ends of the brackets 2 are welded to the base 1.

[0028] By adopting the above technical solution, when pressing concrete blocks, the force-applying component 10 is pressed down, and the force-applying component 10 causes the movable frame 11 to be lifted up. Then, the rotating shaft 5 drives the push rod 3 to move up against the tray 13 through the support plate 4. With the cooperation of the top cover 7, the concrete compression molding is achieved. The structure is simple and the operation is very convenient.

[0029] In this embodiment, the force-applying assembly 10 includes a fixed seat 104 welded to the movable frame 11, and the fixed seat 104 is movably connected to the force-applying seat 101 through an axis; the force-applying seat 101 is arranged in an L shape, and the force-applying seat 101 is also welded with a force-applying shaft 102 horizontally therethrough; a force-applying arm 105 is welded on the force-applying seat 101.

[0030] By adopting the above technical solution, when applying force, one end of the force arm 105 is pressed downward, and the force seat 101 is flipped around the force axis 102, so that the other end of the force seat 101 pushes the fixed seat 104 upward, thereby enabling the movable frame 11 to move upward, providing an upward pressure for the compression of the concrete block.

[0031] In this embodiment, the force-applying seat 101 is L-shaped, with a clamping frame 103 movably connected to one end of the force-applying seat 101 near the force-applying arm 105. This clamping frame 103 engages with an arc-shaped positioning block 12 welded to the movable frame 11. A fixed shaft 15 is also welded to the center of the bracket 2 on the side where the movable shaft 9 is located. The movable shaft 9 is movably connected to one end of the top cover 7, and both ends of the movable shaft 9 are rotatably connected to the bracket 2.

[0032] By adopting the above technical solution, when demoulding, the clamping frame 103 is sleeved on the arc-shaped positioning block 12, and then the force arm 105 is pulled outward. Due to the clamping and fixing of the clamping frame 103 and the arc-shaped positioning block 12, the rib plate 8 is flipped around the movable shaft 9, so that the top cover 7 is opened;

[0033] Then continue to pull the force arm 105 outward until the movable frame 11 contacts the fixed shaft 15, and then apply force to the force arm 105. At this time, the movable frame 11 uses the fixed shaft 15 as the turning center to push the support plate 4 upward; thereby making it easier for the top seat 14 to push the concrete block on the tray 13 out of the forming shell 6 to facilitate the demoulding of the concrete block.

[0034] In this embodiment, the ribs 8 are arranged in a trapezoidal shape, and a C-shaped groove is provided on the upper surface of the ribs 8 for locating the force-applying shaft 102. The C-shaped groove facilitates the application of force when pressing and molding the concrete.

[0035] The working principle of the present invention is as follows: when applying force, one end of the force arm 105 is pressed downward, and the force seat 101 is flipped around the force shaft 102, so that the other end of the force seat 101 pushes the fixed seat 104 upward, so that the movable frame 11 is lifted up, and then the rotating shaft 5 drives the push rod 3 to move upward against the tray 13 through the supporting plate 4, and with the cooperation of the top cover 7, the concrete compression molding is achieved;

[0036] During demoulding, the clamping frame 103 is sleeved on the arc-shaped positioning block 12, and then the force-applying arm 105 is pulled outward. Due to the clamping and fixing of the clamping frame 103 and the arc-shaped positioning block 12, the rib plate 8 is flipped around the movable shaft 9, so that the top cover 7 is opened.

[0037] Then continue to pull the force arm 105 outward until the movable frame 11 contacts the fixed shaft 15, and then apply force to the force arm 105. At this time, the movable frame 11 uses the fixed shaft 15 as the turning center to push the support plate 4 upward; thereby making it easier for the top seat 14 to push the concrete block on the tray 13 out of the forming shell 6 to facilitate the demoulding of the concrete block.
