Description

Technical Field

[0001] The utility model relates to the technical field of concrete test block molds, and specifically relates to a detachable concrete test block mold. Background Art

[0002] Concrete test blocks generally refer to cube test blocks. Cube test blocks are used to measure the compressive strength of concrete. Among them, the concrete test block mold is an indispensable tool in the production of concrete test blocks. The test block mold can help produce concrete test blocks for mechanical property testing. After the concrete test block is formed, it needs to be cured for a period of time before demolding. The Chinese patent with the authorized publication number CN212707307U discloses a concrete test block mold, which includes a bottom plate, a movable mold enclosure plate arranged above the bottom plate, and a U-shaped frame. The interior of the movable mold enclosure plate is divided into chambers for filling concrete by partitions. Slide rails are fixedly arranged on both sides of the plate body of the movable mold enclosure plate near the upper edge; guide grooves that can slide axially along the slide rails are arranged on both side feet of the U-shaped frame. A nut is fixedly arranged at the middle position of the U-shaped frame body. A lead screw is installed inside the nut. A pressure plate is fixedly arranged at one end of the lead screw close to the movable mold enclosure plate, and a bolt head is installed at the other end of the lead screw.

[0003] However, in actual application, the above concrete test block mold still has the following problems: When demolding, it is necessary to first knock on the bottom plate to remove the bottom plate, and then move the movable mold enclosure plate to a high place to make the formed concrete test block in the movable mold enclosure plate suspended. Then, the bolt head is screwed, and the formed concrete test block can be pressed out through the pressure plate. The disassembly process is time-consuming and laborious. In addition, during the process of pressing and demolding by the pressure plate, it will also have a certain impact on the test block, such as the test block having corners missing, cracks, uneven surface, etc., affecting the accuracy of the subsequent mechanical property testing of the test block. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a detachable concrete test block mold aiming at the above deficiencies. The disassembly process is not only more time-saving and labor-saving, but also the disassembled concrete test block is more complete, ensuring the accuracy of the subsequent mechanical property testing of the test block.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A detachable concrete test block mold, comprising a base, a rectangular fixed mold and a controller fixed on the base, a sliding sleeve sliding up and down along the rectangular fixed mold, a demolding driving assembly one for driving the sliding sleeve to slide up and down, a demolding cavity arranged in the rectangular fixed mold, and a demolding driving assembly two arranged in the demolding cavity. A movable mold apron is fixed on the sliding sleeve. When the sliding sleeve is in the rising state, the upper surfaces of the movable mold apron and the rectangular fixed mold enclose a mold cavity. A demolding hole communicating with the mold cavity is arranged in the demolding cavity. Both the demolding driving assembly one and the demolding driving assembly two are electrically connected to the controller.

[0007] Further, the demolding driving assembly one includes connecting seats symmetrically fixed on the left and right on the base, a cylinder fixed on the connecting seats, and the piston rod head of the cylinder vertically extends upward to drive and connect the sliding sleeve.

[0008] Further, an air pump is fixed on one side of the base, and the air pump is electrically connected to the controller; the demolding driving assembly one includes a sliding seat sliding up and down in the demolding cavity, multiple electric cylinders for driving the sliding seat to slide up and down, an air cavity arranged in the sliding seat, and an air pipe for communicating the air cavity and the air pump. An abutting column is arranged on the sliding seat opposite to the demolding hole. Multiple connecting holes communicating with the upper surface of the sliding seat are arranged in the air cavity, and the connecting holes are arranged between adjacent abutting columns.

[0009] Further, when the sliding sleeve is in the rising state, the top end of the abutting column is flush with the top end of the demolding hole.

[0010] Further, the outer diameter of the abutting column gradually decreases from bottom to top, and the shape of the demolding hole is adapted to the outer shape of the abutting column.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In practical applications, when the demolding driving assembly one drives the sliding sleeve to be in the rising state, concrete can be injected into the mold cavity; after the concrete is cooled and formed, the controller controls the demolding driving assembly one to drive the sliding sleeve to move down along the rectangular fixed mold to demold the side wall of the concrete test block. At the same time, the demolding driving assembly two makes the bottom of the concrete test block be demolded from the upper surface of the rectangular fixed mold through the demolding hole; the present utility model not only saves time and effort in the disassembly process, but also the disassembled concrete test block is more complete, ensuring the accuracy of the subsequent mechanical property detection of the test block.

Specific embodiments

[0017] As Figure 1 、 Figure 2 and Figure 3 shown, a detachable concrete test block mold includes a base 1, a rectangular fixed mold 2 and a controller 3 fixed on the base 1, a sliding sleeve 4 sliding up and down along the rectangular fixed mold 2, a first demolding drive assembly 5 for driving the sliding sleeve 4 to slide up and down, a demolding cavity 21 arranged in the rectangular fixed mold 2, and a second demolding drive assembly arranged in the demolding cavity 21. A moving mold enclosure 6 is fixed on the sliding sleeve 4. When the sliding sleeve 4 is in the ascending state, the upper surfaces of the moving mold enclosure 6 and the rectangular fixed mold 2 enclose to form a mold cavity. A demolding hole 22 communicating with the mold cavity is arranged in the demolding cavity 21. Both the first demolding drive assembly 5 and the second demolding drive assembly are electrically connected to the controller 3.

[0018] During use, the first demolding drive assembly 5 drives the sliding sleeve 4 to be in the ascending state, and then concrete can be injected into the mold cavity; after the concrete is cooled and formed, the controller 3 controls the first demolding drive assembly 5 to drive the sliding sleeve 4 to move down along the rectangular fixed mold 2 to demold the side wall of the concrete test block. At the same time, the second demolding drive assembly makes the bottom of the concrete test block be demolded from the upper surface of the rectangular fixed mold 2 through the demolding hole 22; the utility model not only saves time and effort in the disassembly process, but also the disassembled concrete test block is more complete, ensuring the accuracy of the subsequent mechanical property test of the test block.

[0019] As Figure 1 、 Figure 2 and Figure 3 shown, the first demolding drive assembly 5 includes connecting seats symmetrically fixed on the left and right of the base 1, and cylinders fixed on the connecting seats. The piston rod head of the cylinder vertically extends upward to drive and connect the sliding sleeve 4; in this embodiment, the piston rod head driven by the cylinder expands and contracts to drive the sliding sleeve 4 to slide up and down along the rectangular fixed mold 2, so that the mold is closed or demolded.

[0020] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, an air pump 7 is fixed on one side of the base 1, and the air pump 7 is electrically connected to the controller 3; the first demolding driving assembly 5 includes a sliding seat 81 slidably connected up and down in the demolding cavity 21, a plurality of electric cylinders 82 for driving the sliding seat 81 to slide up and down, an air cavity 811 arranged in the sliding seat 81, and an air pipe 83 for communicating the air cavity 811 and the air pump 7. An abutting column 84 is arranged on the sliding seat 81 opposite to the demolding hole 22. A plurality of connecting holes 812 communicating with the upper surface of the sliding seat 81 are arranged in the air cavity 811, and the connecting holes 812 are arranged between adjacent abutting columns 84. In this embodiment, during mold closing, the electric cylinder 82 drives the sliding seat 81 to rise in the demolding cavity 21, and the abutting column 84 blocks the demolding hole 22; during demolding, the electric cylinder 82 drives the sliding seat 81 to descend in the demolding cavity 21, so that the abutting column 84 slides out of the demolding hole 22, and a connecting cavity is formed between the upper surface of the sliding seat 81 and the inner wall of the demolding cavity 21. The air pump 7 makes high-pressure gas impact the bottom of the concrete test block through the air pipe 83, the air cavity 811, the connecting holes 812, the connecting cavity and the demolding hole 22, so that the bottom of the concrete test block is separated from the upper surface of the rectangular fixed mold 2 for demolding.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, when the sliding sleeve 4 is in the rising state, the top end of the abutting column 84 is flush with the top end of the demolding hole 22. In this embodiment, when the sliding sleeve 4 is in the rising state, the top end of the abutting column 84 is flush with the top end of the demolding hole 22, so that the formed concrete test block has a more complete shape.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, the outer diameter of the abutting column 84 gradually decreases from bottom to top, and the shape of the demolding hole 22 is adapted to the outer shape of the abutting column 84. In this embodiment, when the outer diameter of the abutting column 84 gradually decreases from bottom to top and the shape of the demolding hole 22 is adapted to the outer shape of the abutting column 84, it is not necessary to completely slide the abutting column 84 out of the demolding hole 22, and the high-pressure gas can demold the bottom of the concrete test block and the upper surface of the rectangular fixed mold 2 through the demolding hole 22.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but they will not deviate from the scope defined by the spirit of the present invention.
