[0002] During the concrete pouring construction on the project site, the strength test of concrete specimens is an important means of construction quality control. Through the test, the rationality of the concrete mix design can be verified, whether the concrete materials meet the requirements of the specifications, and whether the construction process is appropriate, which can help construction personnel to promptly discover and correct possible problems; in order to determine the concrete strength and construction quality, it is necessary to conduct strength tests on the prepared concrete specimens, and the molding of concrete specimens requires the use of molding molds. The molding of concrete specimens is usually done by pouring concrete slurry into the molding mold, and the concrete specimens can be taken out of the molding mold after the concrete solidifies; currently, when preparing concrete specimens, they need to be based on their Special concrete is customized in size so that it can solidify and form, while traditional forming molds are usually one-piece forming structures. Since the sides of the concrete are tightly attached to the inner walls of the forming mold when solidifying, there is a large viscosity and static friction resistance between the inner walls of the one-piece mold and the concrete. Therefore, it is very inconvenient to demold and remove the concrete specimen. The operator is required to turn the solidified concrete downward first, and then shake the mold continuously or hit the forming mold with tools to try to separate the solidified concrete specimen from the forming mold. This disassembly method may cause damage to the sides of the concrete due to viscosity or static friction resistance, resulting in an increase in the defective rate, and the demolding process is slow, time-consuming and labor-intensive.

[0037] This embodiment provides a molding die that is easy to demould, such as Figures 1 to 8 As shown, it includes a base 1, a forming seat 2, a first forming piece 3 and a second forming piece 4, and the forming seat 2 is detachably mounted on the base 1; along the width direction of the forming seat 2, the first forming piece 3 and the second forming piece 4 are respectively located on both sides of the forming seat 2, and the first forming piece 3 and the second forming piece 4 can be turned over after being mounted on the base 1;

[0038] like Figure 3 As shown, this embodiment also includes two end seats 5, which are detachably mounted on the forming seat 2 along the length direction of the forming seat 2. The forming seat 2, the first forming member 3, the second forming member 4 and the two end seats 5 can be together enclosed to form a frame structure with an opening facing upward, and concrete slurry is filled into the frame structure to form a concrete specimen 11 after the concrete slurry is solidified.

[0039] As a preferred embodiment, the base 1 and the forming seat 2 are respectively provided with engaging parts adapted to each other; specifically, the engaging part includes a limiting groove 61 and / or a limiting strip 62 arranged on the side of the base 1 close to the forming seat 2, and a limiting strip 62 and / or a limiting groove 61 arranged on the side of the forming seat 2 close to the base 1, and the limiting strip 62 can be inserted into the limiting groove 61 to achieve the engagement of the base 1 and the forming seat 2. As an exemplary embodiment, Figure 4 and Figure 7 As shown, the limiting groove 61 is arranged on the upper surface of the base 1, and the limiting strip 62 is arranged on the lower surface of the forming seat 2, and the limiting groove 61 is adapted to the limiting strip 62. When the base 1 and the forming seat 2 need to be connected, the limiting strip 62 on the forming seat 2 only needs to be inserted into the corresponding limiting groove 61 on the base 1 to complete the connection between the two. The connection between the base 1 and the forming seat 2 can be completed with a simple insertion action without the use of additional tools or equipment; and through the close combination of the limiting groove 61 and the limiting strip 62, relative movement or dislocation is not easy to occur, the structure is simple, and it can be disassembled and assembled at any time, which is convenient for transportation, storage and maintenance.

[0040] As a preferred embodiment, Figure 6 As shown, this embodiment further includes a connection unit 7, and along the width direction of the base 1, the first molded part 3 and the second molded part 4 are symmetrically connected to the two sides of the base 1 through the connection unit 7. Further, the connection unit 7 includes a connection shaft 72 and at least two connection seats 71, and each connection seat 71 is arranged at intervals along the length direction of the base 1. In this embodiment, the number of connection seats 71 in the connection unit 7 is preferably three, and the connection shaft 72 passes through each connection seat 71 and is rotatably connected to each connection seat 71. The first molded part 3 and the second molded part 4 are symmetrically connected to the two sides of the base 1 through the connection unit 7, respectively. This design helps to maintain the balance and stability of the overall structure.

[0041] Furthermore, if Figure 6 As shown, the connection unit 7 further includes a fastener 73, and each connection seat 71 is installed on the base 1 through the fastener 73. In this embodiment, the fastener 73 is preferably a bolt. The connection seat 71 is installed on the base 1 through the fastener 73. The fastener 73 can loosen or tighten the base 1. The connection seat 71 can be adjusted within a certain range by twisting the fastener 73.

[0042] As a preferred embodiment, Figure 7 As shown, both sides of the forming seat 2 are provided with completely penetrating slots 21, and sealing rubber strips 81 are provided in the slots 21; Figure 8As shown, the outer periphery of the end seat 5 is covered with a sealing sleeve 82. The sealing rubber strip 81 provided in the card slot 21 can effectively block the possible gaps to prevent the concrete slurry from leaking out through these gaps. By opening the card slot 21 completely through the design on both sides of the forming seat 2, the sealing rubber strip 81 can fit tightly in the card slot 21 to form a continuous barrier to ensure its tight fit and good sealing effect. The sealing rubber strip 81 and the sealing sleeve 82 both prevent the concrete slurry from flowing out of the forming mold and play a role in leak prevention.

[0043] As an implementation method, Figure 1 As shown, the base 1 includes two first abutment units 9. Along the length direction of the base 1, the two first abutment units 9 are respectively arranged on both sides of the base 1 (i.e. Figure 1 In the embodiment, the first abutting units 9 are located on the left and right sides of the base 1). By providing two first abutting units 9 for abutting the end seat 5, when the concrete slurry is poured into the forming mold, the two first abutting units 9 will abut the corresponding end seat 5, thereby increasing the stability of the end seat 5 and preventing the end seat 5 from moving due to the impact or vibration of the concrete slurry.

[0044] Specifically, Figure 1 As shown, the first abutment unit 9 includes a connecting plate 91 and at least one screw 92. In this embodiment, the number of screws 92 is preferably two. The connecting plate 91 is installed at the ends of the first molded part 3 and the second molded part 4. The screw 92 is threadedly connected to the connecting plate 91, and one end of the screw 92 passes through the connecting plate 91 and abuts against the end seat 5. Since the first molded part 3 and the second molded part 4 are rotatably installed on the base 1, by installing the connecting plate 91 at the ends of the first molded part 3 and the second molded part 4, the connecting plate 91 plays a bridge role to stabilize the first molded part 3 and the second molded part 4; at the same time, the screw 92 is threadedly connected to the connecting plate 91. This connection method allows the length of the screw 92 extending into the frame structure to be adjusted by rotating it, thereby achieving accurate abutment with the end seat 5, which is suitable for concrete specimens 11 of different lengths. The screw 92 can be tightly abutted against the end seat 5, thereby increasing the stability of the end seat 5 and preventing the end seat 5 from moving due to impact.

[0045] As another embodiment, Figures 2 to 6As shown, two second abutting units 10 are included. Along the length direction of the base 1, the two second abutting units 10 are spaced apart at the two ends of the forming seat 2, and the two second abutting units 10 are respectively fixed on the upper surface of the forming seat 2. The two second abutting units 10 are respectively fixed on the upper surface of the forming seat 2, and the second abutting units 10 are used to limit the end seat 5, increase the stability of the end seat 5, and prevent the end seat 5 from moving due to impact; however, since the second abutting units 10 are fixedly connected in this embodiment, although the length of the concrete specimen 11 cannot be adjusted, it is easy to operate and has a more compact structure.

[0046] As a preferred embodiment, at least one first connection socket 101 is installed on the top of the first molded part 3, and at least one second connection socket 102 is also installed on the top of the second molded part 4, and the first connection socket 101 is corresponding to the second connection socket 102. When the concrete slurry is filled into the mold, the first connection socket 101 and the second connection socket 102 can firmly limit the first molded part 3 and the second molded part 4 by bolts, ropes or other fasteners 73, ensuring the overall stability of the first molded part 3 and the second molded part 4, and facilitating the curing and molding of the concrete slurry.

[0047] The base 1, the forming seat 2, the first forming part 3, the second forming part 4 and the end seat 5 are made of stainless steel or polymer materials. Such materials are not only durable, but also can reduce the resistance during demoulding. Before pouring the concrete slurry, a layer of release agent can be applied to the inside of the frame structure. The release agent can form a lubricating film, which effectively reduces the adhesion between the concrete specimen 11 and the mold, making demoulding easier. At the same time, during the pouring of the concrete slurry, appropriate vibration can help the concrete slurry to better fill the mold and reduce the generation of bubbles, so that the molded concrete specimen 11 is more uniform and dense, which is helpful for the subsequent demoulding operation.

[0048] Compared with the prior art, the utility model adopts a detachable design among the base 1, the forming seat 2, the first forming piece 3, the second forming piece 4 and the end seat 5, so that the various parts of the forming mold can be disassembled and assembled, which is not only convenient for demoulding, but also convenient for cleaning and maintenance of the mold; the first forming piece 3 and the second forming piece 4 are a flippable structure. After the concrete specimen 11 is formed, the demoulding can be assisted by flipping the forming pieces to reduce the adhesion between the specimen and the mold. At the same time, after the first forming piece 3 and the second forming piece 4 are flipped, the two end seats 5 can also be taken out, so as to facilitate the demoulding of the concrete specimen 11. The structure is compact and practical.

[0049] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
