Description

Technical Field

[0001] The utility model relates to the technical field of concrete test molds, in particular to a concrete test mold which is easy to disassemble and assemble. Background Art

[0002] Concrete test mold is an important means to test and verify the correctness of concrete mix design, concrete strength and other related properties. In construction, by making and testing concrete specimens, it can be ensured that the concrete used in actual construction meets the engineering requirements.

[0003] However, in current construction operations, concrete test molds are mostly cast using a sedimentation method, which is simple but has many shortcomings. As concrete is deposited in the mold by gravity, this can cause stratification of aggregates in the concrete and easily generate bubbles inside the mold, thus affecting the overall quality and accuracy of the test piece.

[0004] Furthermore, when the test mold needs to be dismantled to take out the concrete specimen, the surface of the concrete specimen may adhere to the mold, resulting in defects on the surface of the specimen or affecting the integrity of the specimen, and causing wear of the mold itself.

[0005] In addition, traditional mold disassembly and assembly are cumbersome, which consumes both working hours and human resources, and reduces the overall construction efficiency.

[0006] Therefore, those skilled in the art have proposed a concrete test mold that is easy to disassemble and assemble. Utility Model Content

[0012] Through the above technical means, the top plate can be driven to move up and down through the movement of the hydraulic cylinder, and then the cross plate can be driven to move up and down through the top plate.

[0013] As a preferred embodiment, the rocking mechanism includes a fixed sleeve, a sliding sleeve and a moving rod, the fixed sleeve is symmetrically fixedly connected to one side of the corresponding connecting rod, the sliding sleeve is slidably connected to the inside of the fixed sleeve, the moving rod is slidably connected to the inside of the sliding sleeve, and the sliding sleeve and the fixed sleeve are both provided with springs for resetting, and planes are provided on the corresponding two fixed sleeves and two sliding sleeves.

[0014] Through the above technical means, the sliding sleeve can slide in the fixed sleeve, and the spring will be stretched during the movement, so that the sliding sleeve can be reset, and the moving rod can slide in the sliding sleeve. The moving rod will squeeze the spring when performing the return movement, and the rebound force generated by the squeezing of the spring can also reset the moving rod.

[0016] Through the above technical means, the dual-axis motor rotates, driving the two cams to rotate. The cam contacts the impact plate, driving the impact plate to move and then driving the sliding sleeve to move. The sliding sleeve drives the spring when moving, which allows the sliding sleeve to reset, thereby ensuring that the impact plate is always in contact with the cam.

On the other hand, the contact rod will contact the corners of the moving mold to produce an impact. This impact can move the concrete slurry inside the mold to be more uniform during the molding process. On the other hand, this can also facilitate the separation of the model from the mold during demoulding, and wait until the model manufacturing is completed;

[0033] The test mold structure includes an upper fixing frame 1 and a lower fixing frame 2, the upper fixing frame 1 and the lower fixing frame 2 are arranged in parallel in an upper and lower structure, and four connecting rods 3 are fixedly connected between the upper fixing frame 1 and the lower fixing frame 2;

[0034] In summary, the upper fixing frame 1 and the lower fixing frame 2 are connected via the connecting rod 3, so that the entire device forms an integral structure.

[0035] The test mold structure also includes a horizontal plate 4 and a movable mold 6. The horizontal plate 4 is fixedly connected to the upper fixed frame 1. The horizontal plate 4 is symmetrically provided with hydraulic cylinders 5. The movable mold 6 is arranged below the horizontal plate 4. The top of the movable mold 6 is fixedly connected with a top plate 7. The output ends of the hydraulic cylinders 5 are connected to the top plate 7.

[0036] In summary, the movement of the hydraulic cylinder 5 can drive the top plate 7 to move up and down, and then the top plate 7 can drive the cross plate 4 to move up and down.

The sliding sleeve 9 and the fixed sleeve 8 are both provided with a spring for resetting, and the corresponding two fixed sleeves 8 and two sliding sleeves 9 are both provided with a plane.

[0038] To sum up: the sliding sleeve 9 can slide in the fixed sleeve 8, and the spring will be stretched during the movement, so that the sliding sleeve 9 can be reset, and the moving rod 10 can slide in the sliding sleeve 9, and the moving rod 10 will squeeze the spring when performing the return movement, and the rebound force generated by the squeezing of the spring can also reset the moving rod 10.

[0039] The shaking mechanism also includes a contact rod 11, a mounting support rod 12, a cam 15 and an impact plate 16. The contact rod 11 is fixedly connected between one end of the corresponding two moving rods 10 and a right-angle groove used to match the corner of the moving mold 6 is opened on the side close to the moving mold 6. The mounting support rod 12 is fixedly connected to the plane of the two fixed sleeves 8. The inside of the mounting support rod 12 is fixedly connected with a dual-axis motor 13. Two reinforcement plates 14 are symmetrically fixedly connected to the mounting support rod 12.

[0046] In actual use, the movable mold 6 is placed on the bottom plate 17, and a seal is formed by using the sealing plate 18. Subsequently, grouting is performed through the grouting pipe 19. During the grouting, the dual-axis motor 13 is started, and the dual-axis motor 13 rotates, driving the two cams 15 to rotate. The cam 15 contacts the impact plate 16 to drive the impact plate 16 to move and then drives the sliding sleeve 9 to move. The sliding sleeve 9 drives the spring when moving, which allows the sliding sleeve 9 to reset, thereby ensuring that the impact plate 16 is always in contact with the cam 15. On the other hand, the contact rod 11 will contact the corners of the movable mold 6 to produce an impact, and the excessive stroke will be offset by the stroke of the spring. This impact can make the concrete slurry inside the movable mold 6 more uniform during the mold forming period. On the other hand, this can also facilitate the separation of the model from the mold during demoulding.
