[0001] This utility model belongs to the field of concrete molding technology, specifically relating to a novel concrete specimen molding device. Background Technology

[0002] Research on civil engineering materials is an important part of the field of civil engineering research. Civil engineering materials experiments often require the casting of a large number of standard concrete specimens to study the tensile, compressive, and bending mechanical properties of concrete.

[0003] Traditional concrete molds use an integrated structure, which makes it difficult to slide, disassemble, and separate the mold box after pressing, thus making it inconvenient to remove materials.

[0004] Furthermore, concrete tends to stick to the mold, making demolding difficult and affecting the progress of the experiment. This problem also easily leads to incomplete demolding or damage to the concrete specimens during the demolding process, affecting the performance of the molded concrete specimens in subsequent tensile, compressive, and bending mechanical property studies, and compromising the accuracy of the experimental results.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-4 The present invention provides the following technical solution: a novel concrete specimen molding device, including a device base 1 and a molding die 3 sliding on the device base 1. The molding die 3 adopts a split structure design of two molds on the left and right sides. A drive structure 2 for driving the two molding dies 3 is installed in the middle of the device base 1. A mold cover plate 4 that can be raised and lowered is installed on the top of the device base 1 through a bracket 6. The mold cover plate 4 is inserted into the molding die 3 through a plug-in hole via a plug-in post. A molding base plate 5 is also positioned on the device base 1. A sealing groove 51 is opened around the molding base plate 5. A sealing slide plate 34 is integrally formed on the inner side wall of the lower end of the molding die 3. The molding die 3 slides into the sealing groove 51 through the sealing slide plate 34 and connects with the molding base plate 5.

[0022] In this embodiment, the driving structure 2 includes a bidirectional adjusting screw 21, which is installed in the slide groove 11 of the device base 1. Both ends of the bidirectional adjusting screw 21 are connected to the bottom center of the forming mold 3 via screw sliders 22. The bottom front and rear ends of the forming mold 3 slide within the slide groove 11 via sliders 31. One end of the bidirectional adjusting screw 21 extends out of the slide groove 11 and is connected to an adjusting handle 23. The two forming molds 3 are interconnected via a first insertion post 35 and a first insertion hole 36. Second insertion holes 32 and third insertion holes 33 are respectively provided on the top sides and middle of the forming mold 3. Second insertion posts 42 and third insertion posts 43, respectively adapted to the second insertion holes 32 and third insertion holes 33, are installed on the bottom surface of the mold cover plate 4. The mold cover plate 4 is provided with a connection to the concrete filling pipe. The connection is made through an addition port; by adjusting the handle 23, the bidirectional adjusting screw 21 is rotated, which drives the left and right molding dies 3 to move towards each other via the screw slider 22. At the same time, the molding dies 3 slide along the slide groove 11 on the device base 1 via the slider 31, so that the sealing slide plate 34 at the lower end of the molding die 3 slides into the sealing slide groove 51 of the molding base plate 5, until the left and right molding dies 3 are inserted into each other through the first insertion post 35 and the first insertion hole 36, thereby assembling the molding base plate 5 and the molding die 3 into one piece; the electric telescopic rod 7 is activated to drive the mold cover plate 4 to move downward until it is inserted into the second insertion hole 32 and the third insertion hole 33 respectively through the second insertion post 42 and the third insertion post 43 below it, thereby assembling it firmly with the molding die 3; this facilitates the assembly, disassembly and separation of the molding device and makes it easy to remove materials.

[0023] In order to remove the concrete specimen intact from the molding base plate 5, in this embodiment, four positioning posts 53 are installed at the bottom of the molding base plate 5 and are positioned in the positioning groove of the device base 1 by the positioning posts 53; a demolding air hole is opened in the middle of the molding base plate 5, and a mold plug 52 is used to seal the demolding air hole, with the top surface of the mold plug 52 flush with the upper surface of the molding base plate 5; after removing the molding base plate 5 and the mold plug 52, the demolding gun is used to pressurize the demolding air hole 54 at the bottom of the molding base plate 5, and the concrete specimen can be removed intact from the molding base plate 5.

[0024] To prevent the concrete from firmly adhering and solidifying on the mold surface after molding, the molding mold 3, mold cover plate 4, and molding base plate 5 are made of stainless steel and coated with a nano-silica coating.

[0025] In this embodiment, the bracket 6 is equipped with an electric telescopic rod 7 for driving the mold cover plate 4 to move up and down, and the bottom of the mold cover plate 4 is also provided with a forming pressure plate 41.

[0026] In addition, in order to achieve concrete molding, a vibration motor is installed on the device base 1 to ensure that the concrete is vibrated and compacted in the molding mold 3; the device base 1 is also equipped with a battery for powering the electric telescopic rod 7 and the vibration motor.

[0027] The working principle and usage process of this utility model are as follows: Before casting concrete specimens, the mold plug 52 is inserted into the demolding air hole in the middle of the mold base plate 5. Then, the mold base plate 5 is installed on the device base 1 via the positioning pin 53 and the positioning groove. Then, the adjusting handle 23 drives the bidirectional adjusting screw 21 to rotate, which drives the two forming molds 3 on the left and right to move towards each other via the screw slider 22. At the same time, the forming molds 3 slide along the sliding groove 11 on the device base 1 via the slider 31, so that the lower end of the forming mold 3 is sealed. The slide plate 34 slides into the sealed groove 51 of the forming base plate 5 until the two forming molds 3 on the left and right are inserted into each other through the first insertion post 35 and the first insertion hole 36, thereby assembling the forming base plate 5 and the forming mold 3 into one unit. Finally, the electric telescopic rod 7 is activated to drive the mold cover plate 4 to move downward until it is inserted into the second insertion hole 32 and the third insertion hole 33 through the second insertion post 42 and the third insertion post 43 below it, thereby assembling it firmly with the forming mold 3; this facilitates the assembly, disassembly and separation of the forming device and makes it easy to remove materials.

[0028] When molding the concrete specimen, concrete is filled into the mold through the concrete filling port on the mold cover plate 4, and then flattened by the forming pressure plate 41 at the bottom of the mold cover plate 4.

[0029] After the concrete specimen is formed, the mold cover plate 4 is opened, and the left and right forming molds 3 are opened using the drive structure 2. The forming base plate 5 is removed, and the mold plug 52 is removed. The demolding gun is used to pressurize the demolding air holes 54 at the bottom of the forming base plate 5, and the concrete specimen can be completely removed from the forming base plate 5. Compared with traditional molds, the forming molds 3, mold cover plate 4, and forming base plate 5, which are coated with nano-silica, cannot firmly adhere to the mold surface after the concrete is formed. This allows the mold to be quickly and cleaned with a high-pressure water gun, improving experimental efficiency and extending the life of the mold device.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
