Description

Technical Field

[0001] The utility model belongs to the technical field of experimental mold testing equipment, and specifically relates to a portable concrete mold making and demoulding integrated device. Background Art

[0002] The existing demoulding methods for concrete specimens are mainly manual demoulding and impact demoulding.

[0003] Manual demoulding relies on human power to collide with the test mold carrying the test block, and the test block is separated from the test mold under the action of the collision force. The demoulding efficiency is low and the utilization rate of human resources is low. During the demoulding process, the edges and corners of the test block will be damaged to a certain extent, resulting in defects in the molded test block. At the same time, the steel mold of the concrete test block will also be greatly worn, affecting the service life of the test mold. The defective test block obtained after demoulding will affect the subsequent tests, affecting the detection performance of the concrete and the accuracy of the test.

[0004] Impact demoulding mainly uses air pressure and hydraulic pressure to separate the test block and the test mold. However, there are impact holes on the test mold, and tape needs to be covered above the reserved holes to prevent leakage. Even so, leakage of test molds is still common in actual operation. At the same time, impact demoulding requires a complete set of hydraulic and air pressure devices, which is costly. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a portable concrete mold making and demolding integrated device, which has a simple structure, low manufacturing cost, and will not cause significant damage to the test block, thereby improving the demolding efficiency.

[0008] As an optional technical solution of the utility model, the air pump cover includes a pump body and a connecting body; the pump body is arranged above the connecting body, and the connecting body is connected to the upper end of the cylinder; the external inflation hole is arranged on the upper surface of the pump body; the inflation partition is arranged inside the connecting body.

[0009] As an optional technical solution of the utility model, a spring for resetting the pump body is provided in the pump body; the upper end of the spring is fixed to the top of the pump body, and the lower end is connected to the connecting body.

[0010] As an optional technical solution of the present invention, the pump body and the connecting body are connected by a snap fastener.

[0011] As an optional technical solution of the utility model, the inflatable partition includes an inner inflation hole, an inflatable diaphragm and an inflatable baffle; the inner inflation hole is arranged on the inflatable baffle, and the inflatable diaphragm is arranged below the inner inflation hole; the inflatable diaphragm and the inner inflation hole cooperate with each other for unidirectional conduction of air.

[0012] As an optional technical solution of the present invention, the bottom cover is detachably mounted on the lower end of the cylinder.

[0013] As an optional technical solution of the utility model, it also includes a labeling area for marking the test block; the labeling area is arranged on the upper surface of the air pump cover.

[0014] As an optional technical solution of the utility model, it also includes an age dial for marking the age; the age dial is arranged on the upper surface of the inflation pump cover.

[0024] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0025] Example 1

[0026] This embodiment provides a portable concrete mold making and demoulding integrated device, such as Figure 1 As shown, it comprises a cylinder 1, an air pump cover 2 and a bottom cover 3. The air pump cover 2 is arranged at the upper end of the cylinder 1. The bottom cover 3 is arranged at the lower end of the cylinder 1.

[0027] Furthermore, the bottom cover 3 is detachably mounted on the lower end of the cylinder body 1 .

[0028] Furthermore, in this embodiment, the cylinder 1 is made of ABS plastic. ABS plastic has high surface hardness, good wear resistance, and good strength, impact resistance and rigidity. At the same time, ABS plastic has good chemical resistance and good corrosion resistance to various chemicals.

[0029] like Figure 2 and 3 As shown, an external inflation hole 6 is provided on the upper surface of the inflation pump cover 2, and an inflation partition 9 for unidirectionally conducting air is provided inside the inflation pump cover 2.

[0030] Furthermore, the air pump cover 2 comprises a pump body 2.1 and a connector 2.2. The pump body 2.1 is arranged above the connector 2.2, and the connector 2.2 is connected to the upper end of the cylinder 1. The outer air filling hole 6 is arranged on the upper surface of the pump body 2.1. The air filling barrier 9 is arranged inside the connector 2.2.

[0031] Furthermore, a spring 4 is provided inside the pump body 2.1 for resetting the pump body 2.1. The upper end of the spring 4 is fixed to the top of the pump body 2.1, and the lower end is connected to the connector 2.2.

[0032] Furthermore, in this embodiment, the pump body 2.1 and the connector 2.2 are connected by a buckle 8. The buckle 8 prevents the pump body 2.1 and the connector 2.2 from being separated after being inflated.

[0033] Working principle:

[0034] Before use, assemble the bottom cover 3 and the cylinder 1, apply oil to the inside of the cylinder 1, and pour from the upper end of the cylinder 1. After pouring, cover it with the air pump cover 2. During the concrete molding process, you only need to place the device on a vibration table for shaking, because the device itself has high strength, high hardness and good sealing, which can well protect the quality of the concrete. After reaching the target age, demolding is performed, open the bottom cover 3, open the external air hole 6, block the external air hole 6 with your thumb and press the air pump cover 2, and fill air from the air pump cover 2 into the cylinder 1. The air-filled interlayer 9 can prevent the air from overflowing, so that the air below the air-filled interlayer 9 is filled with air to form high pressure. After pressing to the bottom, release the thumb, and the air pump cover 2 rebounds due to the internal spring 4 until the air pump cover 2 rebounds to the highest point. Repeat the above steps until the air pressure below the air-filled interlayer 9 is large enough, and the test block is removed from the cylinder 1, and demolding is completed.

[0035] If demoulding is not successful once, the demoulding operation can be repeated until the test block is removed. The device can be reused after cleaning.

[0036] Example 2

[0037] This embodiment provides other implementation methods of the portable integrated concrete mold making and demolding device based on the first embodiment.

[0038] like Figure 4 As shown, the inflatable barrier layer 9 includes an inner inflatable hole 9.1, an inflatable diaphragm 9.2 and an inflatable baffle 9.3. The inner inflatable hole 9.1 is arranged on the inflatable baffle 9.3, and the inflatable diaphragm 9.2 is arranged below the inner inflatable hole 9.1. The inflatable diaphragm 9.2 cooperates with the inner inflatable hole 9.1 to conduct air in a one-way manner and prevent air from overflowing.

[0039] Furthermore, when the air pump cover 2 is pressed, air is filled into the cylinder 1 from the inner space of the air pump cover 2 through the inner air filling hole 9.1, and the air filling membrane 9.2 can prevent the air from overflowing and conduct the air in a unidirectional manner. After the pressing is completed, the air filling membrane 9.2 and the air filling partition 9.3 are tightly attached under air pressure to prevent air from flowing back.

[0040] like Figure 3 As shown, the device also includes a labeling area 5 and an age dial 7.

[0041] Furthermore, the labeling area 5 is provided on the upper surface of the air pump cover 2 and is used for marking the test block.

[0042] Furthermore, the age dial 7 is arranged on the upper surface of the air pump cover 2 for marking the age. Commonly used curing ages are 3, 7, 14 and 28 days, and the pointer can be moved to the corresponding scale.

[0043] Furthermore, after the pouring is completed, the pointer of the age dial 7 is moved to the slot corresponding to the target age, and a label with the test block number is attached to the labeling location 5 to facilitate identification.
