[0002] Prefabricated building components can meet different prefabrication requirements by changing the style of the components and blocking certain areas, so as to set reserved spaces such as doors and windows at the components. Not only wall components, but also stairs and certain load-bearing parts in the building can be prefabricated. In the existing prefabricated parts production, the rational use of release agents has a great influence on the quality of prefabricated components.

DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: Figure 1 and Figure 2 As shown, a mold for producing assembled building components includes a casting mold 1, a window frame 11 is arranged in the casting mold 1, the window frame 11 is arranged at the bottom of the casting mold 1, and the defects of the outer shape such as windows are reserved by the outer shape to avoid concrete pouring, a positioning frame 12 is arranged above the casting mold 1, and a plurality of telescopic sliding rods 13 are arranged on the outer sides of the casting mold 1 and the positioning frame 12, each of the telescopic sliding rods 13 is slidably connected with the casting mold 1 and the positioning frame 12, and the telescopic sliding rods 13 control the upper and lower positions of the positioning frame 12 by electric telescopic extension; A plurality of telescopic material control rods 14 are sleeved in the positioning frame 12. In the rectangular component shape of the positioning frame 12, a telescopic material control rod 14 is arranged on each of the four faces of the positioning frame 12. One end of each telescopic material control rod 14 passes through the positioning frame 12 and is connected to a telescopic sliding rod 13. The telescopic material control rod 14 and the telescopic sliding rod 13 are both controlled by electric telescopic movement. The other end of each telescopic material control rod 14 is movably connected to a casting pipe 15. The telescopic material control rods 14 connected on the four faces of the positioning frame 12 respectively adjust the movement of the casting pipe 15 in the same plane through different telescopic degrees, thereby realizing the movement of the casting pipe 15 in the positioning frame 12. At the same time, the pouring pipe 15 introduces concrete from the outside through an external feed pump, and the end of the pouring pipe 15 close to the telescopic material control rod 14 is connected to the telescopic pipe 2, and the telescopic pipe 2 is extended and retracted through electric control. The telescopic material control rod 14 and the telescopic sliding rod 13 can control the movement of the pouring pipe 15 and the telescopic pipe 2 in the up and down, front and back, left and right directions. Through the above movement, the distance between the pouring pipe 15 for pouring concrete and the pouring mold 1 can be effectively adjusted, thereby ensuring the smooth pouring of concrete.

[0022] The telescopic tube 2 is divided into an inner tube 21 and an outer tube 22. The telescopic tube 2 is specifically an electrically controlled telescopic structure. The inner tube 21 can be electrically controlled to be telescopic relative to the outer tube 22. In the casting mold 1, the inner tube 21 is telescopic relative to the outer tube 22. When the casting tube 15 is completely close to the casting mold 1, the bottom impregnation block 3 and the side impregnation block 4 can be more conveniently controlled to better spray the release agent on the inner side and bottom surface of the casting mold 1. Four zoom rectangular blocks 23 are arranged on the outer side of the inner tube 21, and the two ends of each zoom rectangular block 23 are respectively connected to one end of other zoom rectangular blocks 23, and the two ends of each zoom rectangular block 23 are set to an inclination angle of 45°. Each zoom rectangular block 23 is connected to a plurality of zoom telescopic rods 24 on a side close to the inner tube 21, and the zoom telescopic rods 24 are electrically controlled to adjust the distance between the zoom rectangular block 23 and the inner tube 21. The outer side surface of the inner tube 21 is provided with a plurality of circular arrays of matching slide rails 211, and each zoom telescopic rod 24 is slidably connected to a matching slide rail 211. Through the sliding connection between the zoom telescopic rod 24 and the matching slide rail 211, the zoom rectangular block 23 can conform to the inner tube 21 through electrical control. The telescopic rod 24 slides in the axial direction, and the extension and retraction of the telescopic rod 24 and the sliding at the matching slide rail 211 can effectively adjust the orientation between the telescopic rectangular block 23 and the inner tube 21, so as to better adapt to the casting mold 1 provided with the window frame 11. According to the distance between the inner side surface of the casting mold 1 and the outer side surface of the window frame 11, it can avoid that the spraying of the release agent is affected by the size of the rectangle formed by the telescopic rectangular block 23 being smaller than the distance between the casting mold 1 and the window frame 11. At the same time, the sliding of the telescopic rod 24 at the matching slide rail 211 can make the telescopic rectangular block 23 slide from a place on the inner side surface of the casting mold 1 close to the bottom surface of the casting mold 1 to a place on the inner side surface of the casting mold 1 close to the top surface of the casting mold 1.

[0023] like Figure 2 and Figure 3As shown, the two ends of each zoom rectangular block 23 are movably connected to one end of the other two zoom rectangular blocks 23, and the four zoom rectangular blocks 23 are connected to each other to form a rectangle. The zoom rectangular block 23 is a telescopic structure. The zoom rectangular block 23 includes a center block 231 and a side block 232. The two ends of the center block 231 are respectively provided with a side block 232. A pressure sensor connected to the center block 231 is provided in the side block 232. According to the expansion and contraction of the zoom telescopic block, the center block 231 is electrically controlled to expand and contract relative to the center block 231 by the side blocks 232 on both sides, so that the four zoom rectangular tubes can still be in a state of being connected to each other at both ends. When the telescopic rod 24 is retracted, the pressure sensor of the side block 232 is increased, and the central block 231 controls the side block 232 to retract accordingly. When the telescopic rod 24 is extended, the pressure sensor of the side block 232 is increased, and the central block 231 controls the side block 232 to extend accordingly. The end of each side block away from the central block 231 is set at a 45° angle. No matter how the central tube controls the side block 232 to retract relative to the central block 231, the end of the side block 232 set at 45° will be docked with the side block 232 in another telescopic rectangular block 23, so that the four telescopic rectangular tubes can continue to maintain a rectangular shape. like Figure 4 and Figure 5 As shown, each of the central block 231 and the side block 232 is provided with a plurality of liquid spraying ports 25 on the side away from the inner tube 21 and the side close to the bottom surface of the casting mold 1, and each of the liquid spraying ports 25 is arranged in a linear array along the central block 231 and the side block 232, and one end of each side block 232 close to the central block 231 is partially embedded in the central block 231, and the liquid spraying ports 25 provided on the surface of the part of the side block 232 embedded in the central block 231 are blocked by the central block 231 and thus cannot spray liquid, and each scaling matrix The top of the block 23 is respectively provided with one end of an infusion tube 251, and the other end of the infusion tube 251 is connected to a liquid storage ring 252. The infusion tube 251 guides the liquid in the liquid storage ring 252 to the liquid spray port 25 at each center block 231 and the side block 232. The liquid storage ring 252 is sleeved on the outer side surface of the outer tube 22. A connecting tube 253 is provided on the top of the liquid storage ring 252. The connecting tube 253 is externally connected to a booster pump. The booster pump pushes the liquid in the liquid storage ring 252 through the infusion tube 251 through the connecting tube 253 to flow to the liquid spray port 25.

[0024] A bottom wetting block 3 is provided at the bottom of each scaling rectangular block 23, and the bottom wetting block 3 includes a bottom pad 32, a bottom storage roll 33 and a first motor 34. Each side block 232 is provided with a bottom groove 31 at one end away from the center block 231, and the opening of the bottom groove 31 is toward the bottom of the side block 232. A bottom storage roll 33 is hinged in each bottom groove 31, and the outer side surface of the bottom storage roll 33 is also toward the opening of the bottom groove 31. Each bottom storage roll 33 passes through the side block 232 and is coaxially connected to a first motor 34. The first motor 34 is externally connected to a power supply. The two bottom The storage rolls 33 are respectively movably connected to one end of the bottom pad 32, and the two bottom storage rolls 33 are respectively controlled to rotate by a first motor 34. The two first motors 34 can adjust the fit and separation of the bottom pad 32 with the center block 231 and the side block 232 by rotating in opposite directions. At the same time, the two bottom storage rolls 33 can be controlled by the opposite direction movement of the two first motors 34 to jointly provide a pulling force to the bottom pad 32, thereby controlling the bottom pad 32 to leach a certain amount of demoulding liquid under pressure, which can effectively control the content of the demoulding agent in the middle of the bottom of the casting mold 1, and can adjust the amount of the demoulding agent as needed; At the same time, the two first motors 34 can control the movement of the bottom pad 32 connected to the two bottom storage rolls 33 by rotating in the same direction. The bottom pad 32 stored in one bottom storage roll 33 will decrease, and the bottom pad 32 stored in the other bottom storage roll 33 will increase. The contact portion between the bottom pad 32 and the center block 231 and the side block 232 can be conveniently adjusted by the rotation of the first motor 34, so that the demoulding liquid can be effectively sprayed on the bottom pad 32 through the liquid spraying port 25 again, and the demoulding liquid content of the bottom pad 32 in the contact portion with the center block 231 and the side block 232 can be readjusted. Each zoom rectangular block 23 is provided with a side infiltration block 4 on the side away from the inner tube 21, and the side infiltration block 4 includes a side pad 42, a side storage roll 43, a second motor 44 and a limit block 45. Each side block 232 is provided with a side groove 41 at one end away from the center block 231, and the opening of the side groove 41 is facing the side of the side block 232 away from the inner tube 21, and the outer side surface of the side storage roll 43 is also facing the opening of the side groove 41 of the side block 232. A side storage roll 43 is hinged in each side groove 41, and each side storage roll 43 is coaxially connected to a second motor 44 through the side block 232. The second motor 44 is externally connected to a power source, and two side storage rolls 43 are respectively movably connected to one end of the side pad 42, and the two side storage rolls 43 are respectively controlled to rotate by a second motor 44. The two second motors 44 can adjust the fit and separation of the side pad 42 with the center block 231 and the side block 232 by rotating in opposite directions. At the same time, the two side storage rolls 43 can be controlled by the opposite direction movement of the two second motors 44 to jointly provide a pulling force to the side pad 42, thereby controlling the side pad 42 to leach a certain amount of demoulding liquid under pressure, which can effectively regulate the content of the demoulding agent in the inner side of the casting mold 1, and can realize the adjustment of the amount of the demoulding agent as needed; At the same time, the two second motors 44 can control the movement of the side pads 42 connected to the two side storage rolls 43 by rotating in the same direction, so that the side pads 42 stored in one side storage roll 43 will decrease, and the side pads 42 stored in the other side storage roll 43 will increase. The contact portion between the side pads 42 and the center block 231 and the side block 232 can be conveniently adjusted by the rotation of the second motors 44, so that the side pads 42 can be effectively sprayed with demoulding liquid through the liquid spraying port 25 again, and the content of demoulding liquid in the contact portion between the side pads 42 and the center block 231 and the side block 232 can be readjusted. The size of each liquid spraying port 25 is smaller than that of the bottom pad 32 or the side pad 42 , and each liquid spraying port 25 is covered by the bottom pad 32 or the side pad 42 , respectively.

[0025] A limit block 45 is provided on both sides of each center block 231. Each limit block 45 and the side pad 42 connected to the same zoom rectangular block 23 are in contact with each other. A round ball 451 is embedded on the surface of each limit block 45. The round ball 451 is movably connected to the limit block 45. The limit block 45 is sleeved with the side pad 42. The two larger surfaces of the side pad 42 are in contact with the round ball 451 in the limit block 45 and the center block 231 respectively. The two side storage rolls 43 are rotated in the same direction by the second motor 44, and the side pad 42 moves from one side to the other. The side storage roll 43 moves toward the other side storage roll 43, and the ball 451 rotates synchronously under the premise of contacting the side pad 42. The contact between the cylinder and the side pad 42 can control the side pad 42 to better fit with the center block 231 and the side block 232, thereby preventing the release agent spraying effect from being poor due to the side pad 42 not fitting well with the center block 231 and the side block 232 when the release liquid is sprayed on the inner side of the casting mold 1, and at the same time causing signs of release agent dripping, thereby affecting the quality of the prefabricated component after molding.

[0026] The working process of this embodiment is as follows: the telescopic sliding rod 13 and the telescopic material control rod 14 are adjusted in advance as needed, and the casting tube 15 is adjusted to a suitable position between the casting mold 1. At the same time, the bottom infiltration block 3 and the side infiltration block 4 are installed or not as needed, and the expansion and contraction between the inner tube 21 and the outer tube 22 are controlled, and then the sliding of the telescopic rod 24 at the matching slide rail 211 is controlled, and then the orientation of the telescopic rectangular block 23 relative to the inner side of the casting mold 1 is adjusted. According to the distance between the window frame 11 and the inner side of the casting mold 1, the telescopic rod 24 is controlled to expand and contract. Then, the center block 231 controls the expansion and contraction of the side block 232 by electrically controlling the expansion and contraction of the center block 231, and controls the expansion rectangular block 23 that is connected to form a rectangle to fit with the inner side of the casting mold 1. Then, the booster pump controls the demoulding liquid in the storage ring to enter the infusion pipe 251 until the liquid spray port 25 through the connecting pipe 253. If the side block 232 is not installed with the bottom infiltration block 3 and the side infiltration block 4, the demoulding liquid will directly contact the inner side of the casting mold 1. If the side block 232 is installed with the bottom wetting block 3 and the side wetting block 4, the first motor 34 and the second motor 44 are used to control the fitting of the bottom pad 32 and the side pad 42 with the center block 231 and the side block 232, and the side pad 42 is controlled to be embedded in the limit block 45 and contact with the ball 451, and the release agent is in contact with the bottom pad 32 and the side pad 42. The release agent wets the bottom pad 32 and the side pad 42, and then the side pad 42 can contact with the inner side surface of the casting mold 1, the bottom pad 32 can contact with the bottom surface of the casting mold 1, and the side pad 42 and the bottom pad 32 can make the demoulding liquid evenly sprayed on the inner side surface of the casting mold 1, by controlling the sliding of the telescopic rod 24 at the matching slide rail 211 and the different telescopic material control rods The extension and retraction of 14 can control the side pads 42 and the bottom pad 32 to spray the release agent on the parts between the casting mold 1 and the window frame 11 that need to contact with the concrete, and then the liquid spray port 25 is stopped from spraying the release agent by controlling the booster pump and the liquid storage ring 252, and the bottom pad 32 or the side pad 42 soaked with the release agent is respectively stored by the bottom storage roll 33 and the side storage roll 43 according to the control between the first motor 34 and the second motor 44. The bottom pad 32 and the side pad 42 that are not soaked with the release agent are re-contacted with the liquid spray port 25 to absorb the residual release agent, and then the feed pump is controlled to pour concrete into the casting mold 1 through the casting pipe 15 for subsequent prefabricated parts production.
