[0025] When the concrete test block is demolded, first, the air pump gun is inserted into the air inlet of the mold, then the water pump in the water tank 5 is started to work, the water pump can pump out water, then the water flows into the air pump gun through the water pipe 501, and finally flows into the mold through the water outlet assembly, the gap between the concrete test block and the mold can be filled through the water flow, then the pump body 1 is started to work, the air pump gun is inflated through the air pipe 101, so that the mold can be inflated, at this time, the high-pressure gas will not flow out through the gap between the test block and the mold, and the power of the gas will act on the test block, so that the concrete test block can be quickly pushed out of the mold, the test block demolding efficiency is improved, and the sealing assembly is arranged, so that when water is added to the mold, the sealing property between the air pump gun and the air inlet of the mold is improved, and the water flow is prevented from overflowing from the air inlet of the mold to affect the subsequent demolding work.
[0026] As shown in Figures 1 to 3 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the air pump gun comprises a gun body 2, a mounting pipe 3 arranged at the output end of the gun body 2, and a connecting pipe 4 screwedly arranged at the end of the mounting pipe 3 away from the gun body 2;
[0027] The water outlet assembly comprises a fixing sleeve 6 arranged outside the connecting pipe 4, a flow cavity 401 arranged inside the connecting pipe 4, and a plurality of drainage holes 402 opened in the end face of the connecting pipe 4 and communicated with the flow cavity 401, and the inner wall of the fixing sleeve 6 is provided with a slot 601 communicated with the flow cavity 401, and one end of the water pipe 501 away from the water tank 5 is connected with the fixing sleeve 6;
[0028] First, the connecting pipe 4 at the front end of the gun body 2 is inserted into the air inlet of the mold, and the fixing sleeve 6 abuts against the outer wall of the mold, when the water pump is started, water can flow into the inside of the fixing sleeve 6 through the water pipe 501, then flow into the flow cavity 401 in the connecting pipe 4 through the slot 601, and finally flow into the mold through the drainage holes 402, so as to fill the gap between the test block and the mold.
[0029] As shown in Figure 3 and Figure 4 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the sealing assembly comprises a first sealing sleeve 7 arranged outside the connecting pipe 4 and a second sealing sleeve 701 arranged on the side wall of the fixing sleeve 6, and the side wall of the fixing sleeve 6 is provided with a plurality of through holes 602 respectively communicated with the first sealing sleeve 7 and the second sealing sleeve 701;
[0030] When water is added to the mold, the water entering the inside of the fixing sleeve 6 also flows into the first sealing sleeve 7 and the second sealing sleeve 701 through the through holes 602, so that the first sealing sleeve 7 and the second sealing sleeve 701 expand after being filled with water, so as to improve the sealing property between the connecting pipe 4 and the air inlet of the mold, and prevent the water flow from overflowing through the air inlet to affect the subsequent inflation and demolding work.
[0031] Among them, the inner wall of the connecting tube 4 is provided with an air bag 12 extending into the interior of the flow cavity 401; after adding water to the mold, the water pump is turned off, and when the pump body 1 is started to inflate the interior of the mold, the high-pressure gas passing through the inside of the connecting tube 4 will enter the air bag 12, and cause the air bag 12 to bulge and press against the inner wall of the flow cavity 401, thereby isolating the flow cavity 401 and preventing the gas from entering the flow cavity 401 through the drainage hole 402 and affecting the demolding speed.
[0032] like Figure 3 and Figure 5 As shown, as a preferred embodiment, based on the above method, further, the inner wall of the connecting pipe 4 is slidably connected with a filter plate 8, and the outer wall of the filter plate 8 is provided with a scraper 801 in contact with the inner wall of the connecting pipe 4;
[0033] A positioning ring 9 is fixedly connected to the inner wall of the connecting tube 4. A plurality of fixed cylinders 10 are provided on the side wall of the positioning ring 9. A push rod 11 is slidably connected inside the fixed cylinder 10. A spring 1101 is provided between the push rod 11 and the inner bottom wall of the fixed cylinder 10. The end of the push rod 11 away from the fixed cylinder 10 is connected to the side wall of the filter plate 8.
[0034] When the connecting tube 4 is inserted into the mold, the filter plate 8 provided can block dust and impurities, preventing dust and impurities on the test block in the mold from entering the inside of the connecting tube 4. When the inside of the mold is inflated, the high-pressure gas will push the filter plate 8 to move, and drive the push rod 11 to slide toward the outside of the fixed cylinder 10 to stretch the spring 1101. The moving filter plate 8 will also push out some of the dust and impurities attached to the inner wall of the connecting tube 4 through the scraper 801, keeping the inside of the connecting tube 4 clean. When the test block is pushed out of the mold by the high-pressure gas, the inflation is stopped. At this time, the force on the spring 1101 is released, which will drive the push rod 11 and the filter plate 8 to slide back to the inside of the connecting tube 4.
[0035] The working principle of the present utility model is as follows: when demolding a concrete test block, the connecting pipe 4 at the front end of the gun body 2 needs to be inserted into the air inlet on the mold and the fixing sleeve 6 needs to be in contact with the outer wall of the mold. Then, when the water pump is started, water can be passed into the fixing sleeve 6 through the water pipe 501, and then flows into the flow cavity 401 inside the connecting pipe 4 through the notch 601, and finally flows into the mold through the drainage hole 402, thereby completing the filling of the gap between the test block and the mold. When water is added to the mold, the water entering the fixing sleeve 6 will also enter the first sealing sleeve 7 and the second sealing sleeve 701 through the through hole 602. Therefore, the first sealing sleeve 7 and the second sealing sleeve 701 will expand and bulge after being filled with water, thereby improving the sealing between the connecting pipe 4 and the mold air inlet, preventing water from overflowing through the air inlet and affecting the subsequent inflation and demolding work. Finally, start the pump body 1 and inflate the air pump gun through the air pipe 101, so that the mold can be inflated. At this time, the high-pressure gas will not flow out through the gap between the test block and the mold. The power of the gas will act completely on the test block, so that the concrete test block can be quickly pushed out of the mold, improving the test block detachment efficiency. In addition, the sealing component provided can improve the sealing between the air pump gun and the mold air inlet when water is added to the mold, preventing water from overflowing from the mold air inlet and affecting the subsequent demoulding work.
