DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1 to 4 The utility model provides a kind of technical scheme: a prefabricated building pre-support mold, including mold base 1, cover plate 3, defoaming component 4 and vibration motor 5, the top of mold base 1 is provided with cover plate 3, the top of cover plate 3 is provided with defoaming component 4 on both sides, the top of mold base 1 is provided with lifting component 6 on both sides.

[0027] In the process of constructing prefabricated building wall molds, concrete is first added into the mold groove 2 of the mold base 1. Then, the cover plate 3 is closed to the mold base 1 by the lifting component 6 to provide a seal inside the mold base 1. Subsequently, the defoaming component 4 is used to eliminate air bubbles in the concrete placed inside the mold groove 2. After molding, the cover plate 3 is opened by the lifting component 6 to remove the molded concrete wall.

[0028] Please see Figure 1 , Figure 2 and Figure 3 A prefabricated building mold, the defoaming component 4 includes a vacuum pump 401, an air outlet pipe 402, a valve 403, an air extraction pipe 404, an air outlet valve 405, a sealing gasket 406, and a pressure gauge 407. The vacuum pump 401 is fixedly connected to one side of the upper part of the cover plate 3. The air outlet of the vacuum pump 401 is connected to the air outlet pipe 402. The air inlet of the vacuum pump 401 is connected to the valve 403. The air inlet of the valve 403 is connected to the air extraction pipe 404. The air outlet valve 405 is connected through the other side of the upper part of the cover plate 3. The pressure gauge 407 is installed on the upper side of the sealing gasket 406. Vibration motors 5 are fixedly connected to both sides of the outer wall of the mold base 1. The mold base 1 has a mold groove 2. The other end of the air extraction pipe 404 passes through the cover plate 3. The sealing gasket 406 is fixedly connected to the lower part of the cover plate 3.

[0029] Specifically: When the defoaming component 4 eliminates air bubbles in the concrete placed in the mold groove 2 inside the mold seat 1, the vibration motor 5 is first started to vibrate the mold seat 1 at high frequency. The high-frequency vibration of the mold seat 1 allows the particles in the concrete to move and rearrange continuously within the mold, effectively reducing the porosity and air bubbles inside the concrete, making the concrete denser. At the same time, the valve 403 is opened and the air outlet valve 405 is closed. Then, the vacuum pump 401 is started in conjunction with the air extraction pipe 404 to extract the air inside the mold seat 1, creating a negative pressure inside the mold seat 1. This allows the concrete to be evenly distributed within the mold, avoiding segregation, layering, and other phenomena, ensuring consistent concrete performance in all parts of the wall, improving the stability of the wall quality, and promoting the discharge of air bubbles from the concrete, making the wall surface smoother and flatter, reducing surface defects such as pores and pitting, greatly improving the appearance quality of the wall, making it more in line with the requirements of architectural decoration, and reducing the workload and cost of later repairs and decorations. At the same time, the air pressure level inside the mold seat 1 can be monitored through the air pressure gauge 407.

[0031] When the lifting component 6 automatically lifts the cover plate 3, the driving motor 606 drives the worm 605 to rotate reversely, the rotating worm 605 drives the nut in the worm wheel 607 to move linearly and automatically, the cover plate 3 is lifted, and the limiting block 603 is limited to slide in the limiting hole groove 602, so that the cover plate 3 is automatically lifted, the opening and closing of the cover plate 3 is quickly completed, the operation time of the prefabricated building wall mold is shortened, and the overall production efficiency is improved.

[0032] The working principle of the prefabricated building pre-support mold is as follows: when the prefabricated building wall mold works, firstly, the concrete is added to the mold groove 2 of the mold base 1, secondly, the driving motor 606 drives the worm 605 to rotate forward, the rotating worm 605 drives the nut in the worm wheel 607 to move linearly and automatically, the cover plate 3 is pushed by the lead screw 608 to seal the mold base 1, then the vibration motor 5 is started to vibrate the mold base 1 at high frequency, the mold base 1 vibrated at high frequency can make the particles in the concrete continuously move and rearrange in the mold, effectively reduce the pores and bubbles in the concrete, make the concrete more dense, meanwhile, the valve 403 is opened, the air outlet valve 405 is closed, then the vacuum pump 401 is started to cooperate with the air suction pipe 404 to suck the air in the mold base 1, so that the negative pressure is generated in the mold base 1, the bubbles in the concrete are discharged, after the bubbles are eliminated, the air outlet valve 405 is opened, then the driving motor 606 is started to drive the worm 605 to rotate reversely, the rotating worm 605 drives the nut in the worm wheel 607 to move linearly and automatically, the cover plate 3 is pushed by the lead screw 608 to open the mold base 1, finally, the formed concrete wall is taken out, thus the working principle and working process of the prefabricated building pre-support mold are completed, and the contents not described in detail in the specification all belong to the prior art known to the person skilled in the art.
