Description

Technical Field

[0001] The present invention relates to the technical field of porous brick processing, and particularly to a production mold for porous bricks. Background Art

[0002] Porous bricks are a new type of wall material. Porous bricks include concrete porous bricks, which are made with cement as the gelling material, sand, stones, etc. as the main aggregates, through adding water and stirring, forming, and curing, and have a multi-row small hole structure. During the production process, it can utilize some industrial waste residues and other waste materials, which can not only reduce the dependence on natural resources and lower production energy consumption, but also have good environmental protection benefits; at the same time, its multi-row small hole structure endows it with certain heat insulation and heat preservation properties, which helps to improve the thermal environment of buildings and reduce energy consumption, and is an ideal choice for wall materials.

[0003] In the current production process of porous bricks, first, the prepared concrete mixture is poured into the mold, and then a vibrating rod is inserted into it, and the air bubbles are discharged through vibration. After the concrete mixture coagulates and hardens, demolding is carried out, and the demolded bricks are placed in the sun to dry. However, the hole columns set in the porous brick production mold will hinder the vibrating rod from penetrating deep into the concrete mixture, resulting in the difficulty of fully discharging the air bubbles. For this reason, production workers usually tap the four sides of the mold to shake out the internal air bubbles. However, since it is difficult to maintain a uniform tapping force, this not only easily generates new air bubbles, affecting the production quality of porous bricks, but also may damage the mold.

[0004] Therefore, the present invention provides a production mold for porous bricks to meet the requirements. Summary of the Invention

In addition, after the concrete mixture condenses, it can be pushed out of the fixed mold by means of the rotating assembly, realizing rapid demolding, which is convenient for workers to carry it to a spacious place for drying.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting the rotating assembly, not only can the knocking column on the inner wall of the large-hole column be knocked when rotating, so that the large-hole column drives the small-hole column to shake, and the vibration generated by the cooperation of the two is used to discharge the air bubbles in the concrete mixture in the fixed mold, and at the same time, the collapse generated at the top of the mixture due to the discharge of air bubbles is rolled flat; moreover, by adjusting the rotation direction of the rotating assembly, the redundant concrete mixture can also be shoveled away. In addition, after the concrete mixture condenses, it can be pushed out of the fixed mold by means of the rotating assembly, realizing rapid demoulding, which is convenient for workers to carry it to a spacious place for drying.

[0019] By setting the threaded column, threaded cylinder, first connecting column, abutting cylinder and metal support plate, by rotating the second connecting circular plate clockwise, the threaded column will rotate synchronously with it, and then drive the abutting cylinder to displace along the threaded cylinder on the outer wall of the threaded column, so as to push out the concrete mixture in the fixed mold. In this way, workers can quickly demould the condensed concrete mixture and carry it to a spacious place for drying.

[0020] By setting the second rotating circular plate, the second limiting column, the rotating rod, the rolling cylinder and the shoveling plate, the rotating handle can be rotated. During the rotation of the rotating rod, the rolling cylinder will continuously knock on the two knocking columns on the inner wall of the large-hole column, causing the large-hole column to shake, and driving several small-hole columns to shake. The vibration generated by the shaking of the large-hole column and the small-hole columns can vibrate out the air bubbles in the concrete mixture. At the same time, the shoveling plate can roll flat the collapse generated at the top of the concrete mixture due to the discharge of air bubbles. In addition, by rotating the rotating handle in the reverse direction, the shoveling plate can use the centrifugal force generated by the rotation to remove the excess concrete mixture.

[0021] By setting the pushing column, the first abutting column, the third sliding protrusion, the second abutting column, the Z-shaped fixing plate and the pressing plate, by stepping on the pressing plate, the displacement of the first rotating circular plate can be driven. At the same time, under the limiting action of the third sliding protrusion and the fourth sliding protrusion, the pushing column and the second abutting column can be respectively prevented from rotating during the sliding process, which affects the subsequent operations of the workers. Also, when stepping on the pressing plate, the cable can be subjected to a tensile force, which provides convenience for the subsequent demolding operation of the workers.

[0049] As Figures 1 to 18As shown in the figure, an embodiment of the present invention provides a porous brick production mold, including a fixed mold 1. The fixed mold 1 is a rectangular box body surrounded by four rectangular plastic plates. On both sides of the outer wall of the bottom of the fixed mold 1, support protrusions 101 are symmetrically and fixedly connected. The support protrusions 101 are plastic cuboids. On the outer walls of both sides of the support protrusions 101 near the bottom, slot holes 102 are symmetrically opened. The slot holes 102 are rectangular troughs. On the outer walls of one side of the two support protrusions 101 close to the central axis of the fixed mold 1, first elastic plates 109 are respectively fixed. The first elastic plates 109 are composed of plastic plates with "C" shapes at both ends and a plastic straight plate in the middle. When the first elastic plates 109 are stressed, they will deform along the direction of their bending. On the inner walls of both sides of the fixed mold 1 close to the first elastic plates 109, first avoidance grooves 103 are respectively opened. The first avoidance grooves 103 are rectangular troughs. A mold bottom plate 104 is slidably connected to the inner wall of the fixed mold 1. The mold bottom plate 104 is a rectangular plastic plate. The outer wall contour of the mold bottom plate 104 is adapted to the inner wall contour of the first avoidance groove 103. Therefore, the mold bottom plate 104 can shake on the inner wall of the fixed mold 1. On the top outer wall of the mold bottom plate 104, a large hole column 106 and a number of small hole columns 107 are fixedly connected. The large hole column 106 is a hollow plastic cylinder, and the small hole columns 107 are plastic cylinders. On the inner wall of the large hole column 106, knocking columns 108 are symmetrically and fixedly connected. The knocking columns 108 are semi-circular plastic column bodies. On the bottom outer wall of the mold bottom plate 104, four first avoidance holes 111 distributed in a circular array are opened. The first avoidance holes 111 are circular troughs. The first avoidance holes 111 can provide an avoidance space for the shaking of the mold bottom plate 104. In the middle of the bottom outer wall of the mold bottom plate 104, two limit cylinders 110 are fixedly connected. The limit cylinders 110 are plastic cylinders. When the mold bottom plate 104 shakes, the limit cylinders 110 will displace along with the mold bottom plate 104. At this time, the outer wall of the limit cylinder 110 will contact the middle outer wall of the first elastic plate 109, causing the two ends of the first elastic plate 109 to be stressed and deform along the direction of their bending. Subsequently, under the action of the elasticity of the first elastic plate 109 itself, it will recover the deformation and push the limit cylinder 110 to reset. In this way, with the cooperation of the two first elastic plates 109 and the two limit cylinders 110, the mold bottom plate 104 can shake better, and after the shaking ends, the mold bottom plate 104 can be reset, facilitating the subsequent operation of the worker; a rotating assembly, the rotating assembly can generate vibration by rotation to discharge the air bubbles in the concrete mixture in the fixed mold 1. The rotating assembly is connected to the fixed mold 1.

[0050] By providing a rotating assembly, the present application can not only strike the striking column 108 against the inner wall of the large-hole column 106 during rotation, causing the large-hole column 106 to drive the small-hole column 107 to shake, and using the vibration generated by the cooperation of the two to discharge the air bubbles in the concrete mixture in the fixed mold 1, and at the same time flatten the collapse generated at the top of the mixture due to the discharge of air bubbles, but also adjust the rotation direction of the rotating assembly to remove the excess concrete mixture. In addition, after the concrete mixture condenses, it can be pushed out of the fixed mold 1 with the help of the rotating assembly, which is convenient for workers to carry it to a spacious place for drying.

[0051] As an implementation manner in this embodiment, as Figures 1 to 10As shown, the rotating assembly includes a U-shaped fixing plate 112. One end of the U-shaped fixing plate 112 is inserted into the inner wall of the slot 102. The U-shaped fixing plate 112 is a "U"-shaped metal plate. The outer wall contour of the end of the U-shaped fixing plate 112 close to the fixed mold 1 is adapted to the inner wall contour of the slot 102. Therefore, the U-shaped fixing plate 112 can be inserted into the slot 102. The other end of the U-shaped fixing plate 112 is fixedly connected to a first fixing plate 2 by screws. In this way, the fixed mold 1 can be fixed to the top of the first fixing plate 2 by using the U-shaped fixing plate 112 through screws. A second fixing plate 201 is fixedly connected to the outer side of one side of the first fixing plate 2. The first fixing plate 2 is a rectangular metal plate, and a metal cylinder is fixedly connected to the middle position of the top outer wall of the first fixing plate 2. A first round hole groove 204 is opened on the top outer wall of the first fixing plate 2. The first round hole groove 204 is a circular hole groove. The second fixing plate 201 is a "U"-shaped metal plate. One end of the second fixing plate 201 away from the first fixing plate 2 is fixedly connected to a third fixing plate 202.

With the cooperation of the first fixing plate 2, the second fixing plate 201 and the third fixing plate 202, a supporting force can be provided for the fixed mold 1. Among them, a first rotating groove 205 is opened at the middle position of the bottom outer wall of the first fixing plate 2. The first rotating groove 205 is a circular groove with a cross-section in the shape of a "convex". Four second avoiding holes 203 are opened on the top outer wall of the first fixing plate 2 and are distributed in a circumferential array. The second avoiding holes 203 are circular groove bodies.

A first rotating protrusion 4 is fixedly connected to the top outer wall of the first connecting circular plate 401. The first rotating protrusion 4 is a "convex"-shaped plastic block, and the outer wall contour of the first rotating protrusion 4 is adapted to the inner wall contour of the first rotating groove 205. Therefore, the first rotating protrusion 4 can rotate on the inner wall of the first rotating groove 205. A threaded column 402 is fixedly connected to the bottom outer wall of the first connecting circular plate 401. The threaded column 402 is a plastic cylinder with a threaded groove on its outer wall. One end of the threaded column 402 away from the first connecting circular plate 401 is fixedly connected to a second connecting circular plate 403. The second connecting circular plate 403 is a plastic circular plate. A plurality of first limiting columns 406 are fixedly connected to the bottom outer wall of the second connecting circular plate 403 and are distributed in a circumferential array. The first limiting columns 406 are plastic cylinders with a curved end. A second rotating protrusion 404 is fixedly connected to the middle of the bottom outer wall of the second connecting circular plate 403. The second rotating protrusion 404 is a "convex"-shaped plastic block. A second round hole groove 405 is opened on the bottom outer wall of the second rotating protrusion 404. The second round hole groove 405 is a circular groove body and penetrates through from the top outer wall of the first rotating protrusion 4. A threaded cylinder 5 is screwed onto the outer wall of the threaded column 402. The threaded cylinder 5 is a plastic cylinder,A threaded hole 501 is provided on the outer wall at the top end of the threaded cylinder 5. The threaded hole 501 is a hole groove provided with a threaded groove. The inner wall contour of the threaded hole 501 is adapted to the outer wall contour of the threaded column 402. Therefore, the threaded cylinder 5 can rotate on the outer wall of the threaded column 402.,

[0052] Four first connecting columns 502 distributed in a circular array are fixedly connected to the outer wall of the threaded cylinder 5. The connecting columns are plastic cuboids with a curved end. A butting cylinder 503 is fixedly connected to the outer wall of the top of the first connecting column 502 away from the threaded cylinder 5. The butting cylinder 503 is a plastic cylinder with a curved end. And the outer wall contour of the butting cylinder 503 is respectively adapted to the inner wall contour of the first avoidance hole 111 and the inner wall contour of the second avoidance hole 203 mentioned above. Therefore, the end of the butting cylinder 503 away from the first connecting column 502 can sequentially pass through the second avoidance hole 203 and the first avoidance hole 111 and slide on its inner wall. A sliding column 504 is fixedly connected to the outer wall of the threaded cylinder 5 close to the second fixing plate 201. The sliding column 504 is composed of a plastic cylinder and a plastic circular plate. And the plastic circular plate is fixedly connected to the end of the plastic cylinder away from the threaded cylinder 5. Since a first sliding groove 206 is provided on the outer wall of the middle part of the second fixing plate 201. The first sliding groove 206 is a rectangular groove body with curved ends at both ends. The inner wall contour of the first sliding groove 206 is adapted to the outer wall contour of the sliding column 504. Therefore, the sliding column 504 can slide on the inner wall of the first sliding groove 206 and be limited by it. Therefore, when the threaded column 402 is rotated, the sliding column 504 can give a limiting effect to the threaded cylinder 5 to prevent the threaded cylinder 5 from rotating along with the threaded column 402. The worker first places the metal support plate 105 into the fixed mold 1. The outer wall contour of the metal support plate 105 is adapted to the inner wall contour of the fixed mold 1. And circular grooves adapted to the large hole column 106 and the small hole column 107 are provided on the outer wall of the metal support plate 105. Subsequently, the concrete mixture can be poured into the fixed mold 1. After the concrete mixture condenses, the second connecting circular plate 403 can be rotated clockwise. The second connecting circular plate 403 will drive the threaded column 402 to rotate. At this time, the threaded cylinder 5 will displace in the direction of the first rotating protrusion 4. The butting cylinder 503 will displace along with the threaded cylinder 5, will abut against the bottom outer wall of the metal support plate 105, and will push the metal support plate 105 to slide in the direction of the top of the fixed mold 1, so as to push out the condensed concrete mixture from the fixed mold 1. The above structural settings can push out the concrete mixture from the fixed mold 1 by rotating the second connecting circular plate 403 clockwise, which is convenient for the worker to quickly demold the condensed concrete mixture and carry it to a spacious place for drying.,

[0053] In this embodiment, as Figures 7 to 14As shown in the figure, a rotating cylinder 7 is rotatably connected to the outer wall of the second rotating protrusion 404. The rotating cylinder 7 is a plastic cylinder. First discs 701 and second discs 703 are respectively fixedly connected to both ends of the rotating cylinder 7. Both the first disc 701 and the second disc 703 are plastic circular plates. The diameters of the first disc 701 and the second disc 703 are both larger than the diameter of the rotating cylinder 7. A second rotating groove 704 is formed in the top outer wall of the first disc 701. The second rotating groove 704 is a cylindrical groove in a "convex" shape, and the inner wall contour of the second rotating groove 704 is adapted to the outer wall contour of the second rotating protrusion 404. Therefore, the second rotating protrusion 404 can rotate on the inner wall of the second rotating groove 704, so that when the rotating cylinder 7 is rotated, it will not affect the second connecting circular plate 403. A third rotating groove 705 is formed in the bottom outer wall of the second disc 703. The third rotating groove 705 is a cylindrical groove in a "convex" shape. A third circular hole groove 706 is formed in the bottom inner wall of the second rotating groove 704. The third circular hole groove 706 is a circular groove, and the third circular hole groove 706 penetrates out from the top inner wall of the third rotating groove 705. One ends of two second connecting columns 702 are fixedly connected to the bottom outer wall of the first disc 701, and the other ends of the two second connecting columns 702 are both fixedly connected to the top outer wall of the second disc 703, and the two second connecting columns 702 are symmetric with respect to the rotating cylinder 7. Linking plates 602 are respectively slidably connected to the outer walls of the two second connecting columns 702. The linking plate 602 is a rectangular plastic plate with a curved end. First rotating circular plates 6 are fixedly connected to the ends of the two linking plates 602 away from the rotating cylinder 7. The first rotating circular plate 6 is composed of two plastic hollow circular plates. The thickness of the plastic hollow circular plate located on the outer circle is less than that of the hollow plastic circular plate on the inner circle. A first sliding hole 603 is formed in the top outer wall of the linking plate 602. The first sliding hole 603 is a circular groove, and the inner wall contour of the first sliding hole 603 is adapted to the outer wall contour of the second connecting column 702. Therefore, the linking plate 602 can slide on the outer wall of the second connecting column 702, and when the first rotating circular plate 6 is rotated, it will drive the rotating cylinder 7 to rotate. One end of a tension spring 604 is fixedly connected to the bottom outer wall of the linking plate 602, and the other end of the tension spring 604 is fixedly connected to the top outer wall of the second disc 703. The tension spring 604 is a publicly known prior art, so it will not be elaborated here. When the linking plate 602 slides along the outer wall of the second connecting column 702 towards the second rotating protrusion 404, the tension spring 604 will be subjected to a tensile force and deform along its bent direction. When the tension spring 604 is no longer stressed, it will pull the linking plate 602 to reset. A plurality of second sliding holes 601 distributed in a circumferential array are formed in the outer wall of the first rotating circular plate 6 near the linking plate 602. The second sliding holes 601 are circular grooves. Fillets are respectively arranged on the inner walls of the second sliding holes 601 near the top end and the bottom end of the first rotating circular plate 6, and the inner wall contour of the second sliding holes 601 is adapted to the outer wall contour of the first limiting column 406.This facilitates the insertion of the first limiting post 406 into the second sliding hole 601. Four rotating handles 605 are fixedly connected to the outer wall of the first rotating circular plate 6 and are distributed in a circumferential array. The rotating handle 605 is composed of a plastic cylinder and a plastic sphere. The plastic sphere is fixedly connected to the end of the plastic cylinder away from the first rotating circular plate 6. The arrangement of the rotating handle 605 facilitates the worker to rotate the first rotating circular plate 6. A fifth sliding groove 606 is formed on the outer wall of the bottom of the first rotating circular plate 6. The fifth sliding groove 606 is a "convex"-shaped annular groove. When the first rotating circular plate 6 is pushed to slide in the direction of the second rotating protrusion 404, the linkage plate 602 will slide along the outer wall of the second connecting column 702 following the first rotating circular plate 6. At this time, the tension spring 604 will be subjected to a tensile force and deform along its bent direction. The second sliding hole 601 will be sleeved on the outer wall of the first limiting post 406. Subsequently, the rotating handle 605 can be rotated clockwise, and the first rotating circular plate 6 will drive the second connecting circular plate 403 to rotate clockwise. The above structural arrangement can drive the second connecting circular plate 403 to rotate by rotating the rotating handle 605, causing the threaded column 402 to rotate following the second connecting circular plate 403, thereby driving the above-mentioned abutting cylinder 503 to displace along the outer wall of the threaded column 402 following the threaded sleeve 5, providing convenience for subsequent demolding.,

[0054] In this embodiment, as Figures 7 to 8 and Figures 15 to 16As shown in the figure, a third rotating protrusion 802 is rotatably connected to the inner wall of the third rotating groove 705. The third rotating protrusion 802 is a plastic block in the shape of a "convex". The outer wall contour of the third rotating protrusion 802 is adapted to the inner wall contour of the third rotating groove 705. Therefore, the third rotating protrusion 802 can rotate on the inner wall of the third rotating groove 705. The bottom of the third rotating protrusion 802 is fixedly connected to a second rotating circular plate 8. The second rotating circular plate 8 is a plastic circular plate. A fourth circular hole groove 810 is formed in the outer wall of the top of the third rotating protrusion 802. The fourth circular hole groove 810 is a circular groove body and penetrates out from the outer wall of the bottom of the second rotating circular plate 8. The inner wall contour of the fourth circular hole groove 810 is adapted to the outer wall contour of the cable 809. Therefore, the cable 809 can pass through the inner wall of the fourth circular hole groove 810. A plurality of second limiting columns 801 are fixedly connected to the outer wall of the top of the second rotating circular plate 8. The second limiting columns 801 are plastic cylinders with a curved end. The outer wall contour of the second limiting columns 801 is adapted to the inner wall contour of the second sliding hole 601. And in cooperation with the fillet provided on the inner wall of the second sliding hole 601 near the bottom end of the first rotating circular plate 6 mentioned above, it is convenient for the second limiting columns 801 to be inserted into the second sliding hole 601. When the rotating handle 605 is rotated, it will drive the second limiting columns 801 to rotate and drive the second rotating circular plate 8 to rotate. A rotating rod 803 is fixedly connected to the outer wall of the top of the third rotating protrusion 802. The rotating rod 803 is a metal hollow cylinder. The outer wall contour of the rotating rod 803 is respectively adapted to the inner wall contour of the first circular hole groove 204, the inner wall contour of the second circular hole groove 405 and the inner wall contour of the third circular hole groove 706. Therefore, one end of the rotating rod 803 away from the third rotating protrusion 802 can pass through the inner walls of the third circular hole groove 706, the second circular hole groove 405 and the first circular hole groove 204 in sequence and rotate. One end of the rotating rod 803 away from the third rotating protrusion 802 is set in the shape of a "Ji". And circular groove bodies are formed at both turning points of the rotating rod 803 near the "Ji" shape, which are respectively communicated with the inner wall of the rotating rod 803. A rolling cylinder 804 is sleeved on the outer wall of the rotating rod 803 in the shape of a "Ji". The rolling cylinder 804 is a plastic hollow cylinder. The inner wall contour of the rolling cylinder 804 is adapted to the outer wall contour of the rotating rod 803. Therefore, the rolling cylinder 804 can roll on the outer wall of the rotating rod 803. When the rotating rod 803 rotates, the rolling cylinder 804 can roll and continuously knock on the two knocking columns 108, causing the large hole column 106 to shake.

[0055] One end of the rotating rod 803 away from the third rotating protrusion 802 is fixedly connected with a movable buckle 806. The movable buckle 806 is a "U"-shaped metal plate. The movable buckle 806 is screwed with a screwing plate 807 through a screw. The screwing plate 807 is composed of three parts: plastic circular plates at both ends and a plastic cylinder in the middle. One end of the screwing plate 807 away from the movable buckle 806 is fixedly connected with a shoveling plate 808 on the outer wall. The shoveling plate 808 is a plastic plate with a radian. By adjusting the rotation direction of the rotating rod 803, the shoveling plate 808 can not only remove the excess concrete mixture in the fixed mold 1, but also roll the uneven concrete mixture in the fixed mold 1 flat. A second elastic plate 805 is fixedly connected to the outer wall of the screwing plate 807 close to the shoveling plate 808. The second elastic plate 805 is a "C"-shaped metal plate. When the second elastic plate 805 is stressed, it will deform along its bending direction. A cable 809 is fixedly connected to the outer wall of the screwing plate 807 close to the movable buckle 806. The cable 809 is disclosed in the prior art, so it will not be elaborated here. The outer wall contour of the cable 809 is respectively adapted to the inner wall contour of the rotating rod 803 and the inner wall contour of the fourth circular hole groove 810. Therefore, the other end of the cable 809 first passes through the top of the rotating rod 803, then passes out from the turning point near the "Ji"-shaped top of the rotating rod 803, then passes into the inner wall of the rotating rod 803 from the turning point near the "Ji"-shaped bottom of the rotating rod 803, and then passes out from the fourth circular hole groove 810. By pulling the cable 809, the screwing plate 807 can rotate around the screwing point as the center, so that the shoveling plate 808 is parallel to the pulling rod. This can facilitate the worker to place the metal support plate 105 into the fixed mold 1, and also facilitate the worker to remove the condensed concrete mixture from the fixed mold 1.

[0056] When the cable 809 is no longer pulled, the second elastic plate 805 is no longer stressed, will restore its deformation along the bending direction, and drive the shovel plate 808 to reset. When the rotating handle 605 is rotated clockwise, it will drive the second limiting column 801 to rotate clockwise, and the second rotating circular plate 8 will rotate following the second limiting column 801. At this time, the rotating rod 803 will rotate clockwise. During the rotation of the rotating rod 803, the rolling cylinder 804 will continuously knock on the two knocking columns 108 on the inner wall of the large-hole column 106, causing the large-hole column 106 to shake, driving several small-hole columns 107 to shake. The vibration generated by the shaking of the large-hole column 106 and the small-hole columns 107 can vibrate out the air bubbles in the concrete mixture. The shovel plate 808 will rotate clockwise around the screwing joint of the movable buckle 806 following the rotation of the rotating rod 803. At this time, the outer wall of the protrusion on the shovel plate 808 can flatten the collapse generated at the top of the concrete mixture due to the discharge of air bubbles. When the rotating handle 605 is rotated counterclockwise, the rolling cylinder 804 will still continuously knock on the two knocking columns 108 on the inner wall of the large-hole column 106 during the rotation of the rotating rod 803, and the shovel plate 808 will cooperate with the centrifugal force generated by the rotation to remove the excess concrete mixture. The above structural settings can rotate the rotating handle 605, and during the rotation of the rotating rod 803, the rolling cylinder 804 will continuously knock on the two knocking columns 108 on the inner wall of the large-hole column 106, causing the large-hole column 106 to shake and driving several small-hole columns 107 to shake. The vibration generated by the shaking of the large-hole column 106 and the small-hole columns 107 can vibrate out the air bubbles in the concrete mixture. At the same time, the shovel plate 808 can flatten the collapse generated at the top of the concrete mixture due to the discharge of air bubbles. In addition, when the rotating handle 605 is rotated in the reverse direction, the shovel plate 808 can use the centrifugal force generated by the rotation to remove the excess concrete mixture.

[0057] In this embodiment, as Figures 4 to 6 and Figures 17 to 18As shown, a second sliding groove 207 is formed on the outer wall of the top of the third fixing plate 202 close to the second fixing plate 201. The second sliding groove 207 is a straight groove in a "convex" shape. A third avoidance hole 208 is formed on the outer wall of the top of the third fixing plate 202 at one end close to the second sliding groove 207. The third avoidance hole 208 is a square hole groove. First connecting plates 3 are symmetrically and fixedly connected to the outer walls of the top of the third fixing plate 202 on both sides close to the second sliding groove 207. The first connecting plates 3 are rectangular metal plates. One end of the first connecting plate 3 away from the third fixing plate 202 is fixedly connected to a Z-shaped fixing plate 301. The Z-shaped fixing plate 301 is a metal plate in a "Z" shape. Third sliding grooves 303 and fourth sliding grooves 304 are respectively formed on the outer walls of the Z-shaped fixing plate 301 close to both ends. Both the third sliding groove 303 and the fourth sliding groove 304 are rectangular troughs with arcs at both ends. The third sliding groove 303 and the fourth sliding groove 304 are centrosymmetric about the center of the Z-shaped fixing plate 301, and the third sliding groove 303 is farther from the third fixing plate 202 than the fourth sliding groove 304. For the Z-shaped fixing plate 301 far from the second skeleton, a fourth avoidance hole 302 is formed on the outer wall close to the middle. The fourth avoidance hole 302 is a circular trough, and the inner wall contour of the fourth avoidance hole 302 is adapted to the outer wall contour of the cable 809. Therefore, the cable 809 can pass through the fourth avoidance hole 302. A push column 9 is slidably connected to the inner wall of the fifth sliding groove 606. The push column 9 is a plastic cylinder with an inclined surface at the bottom end. The top end of the push column 9 is fixedly connected to a first sliding protrusion 901. The first sliding protrusion 901 is a plastic block in a "convex" shape. The outer wall contour of the first sliding protrusion 901 is adapted to the inner wall contour of the fifth sliding groove 606. Therefore, the first sliding protrusion 901 can slide on the inner wall of the fifth sliding groove 606. Second sliding protrusions 902 are symmetrically and fixedly connected to the outer wall of the push column 9. The second sliding protrusion 902 is composed of two parts: a plastic cuboid with arcs at both ends and a plastic circular plate. The outer wall contour of the plastic cuboid on the second sliding protrusion 902 is adapted to the inner wall contour of the third sliding groove 303. Therefore, the second sliding protrusion 902 can slide on the inner wall of the third sliding groove 303. A first abutting column 903 is slidably connected to the inner wall of the second sliding groove 207. The first abutting column 903 is an isosceles trapezoidal column made of plastic. A third sliding protrusion 904 is fixedly connected to the bottom outer wall of the first abutting column 903. The third sliding protrusion 904 is a plastic column in a "convex" shape, and the outer wall contour of the third sliding protrusion 904 is adapted to the inner wall contour of the second sliding groove 207. Therefore, the third sliding protrusion 904 can slide on the inner wall of the second sliding groove 207. When the third sliding protrusion 904 slides along the inner wall of the second sliding groove 207 towards the push column 9, the first abutting column 903 will slide along with the third sliding protrusion 904, and the inclined surface at one end of the first abutting column 903 close to the push column 9 will abut against the inclined surface at the bottom end of the push column 9.And it drives the push column 9 to drive the second sliding protrusion 902 to slide along the inner wall of the third sliding groove 303 in a direction away from the third fixing plate 202, and drives the first rotating circular plate 6 to displace in the direction of the second rotating protrusion 404. Moreover, under the limiting sliding action of the third sliding protrusion 904, it can prevent the push column 9 from rotating during the sliding process, which affects the pushing of the first rotating circular plate 6.

[0058] Fourth sliding protrusions 907 are respectively slidably connected to the outer walls of the two fourth sliding grooves 304. The fourth sliding protrusion 907 is composed of two parts: a plastic cuboid with arcs at both ends and a plastic circular plate. Among them, for the plastic cuboid on the fourth sliding protrusion 907, the outer wall contour thereof is adapted to the inner wall contour of the fourth sliding groove 304. Therefore, the fourth sliding protrusion 907 can slide on the inner wall of the fourth sliding groove 304. One ends of the two fourth sliding protrusions 907 are fixedly connected to the same second abutting column 905. The second abutting column 905 is a right trapezoidal column made of plastic. Among them, the inclined surface of the second abutting column 905 faces the direction of the first abutting column 903, and the outer wall contour of the second abutting column 905 is adapted to the inner wall contour of the third avoidance hole 208. Therefore, the second abutting column 905 can slide into the third avoidance hole 208. During the sliding process of the second abutting column 905, the inclined surface of the second abutting column 905 will abut against the inclined surface of the first abutting column 903 and drive the first abutting column 903 to slide along the inner wall of the second sliding groove 207 in the direction of the push column 9. The fourth sliding protrusion 907 will follow the second abutting column 905 to slide along the inner wall of the fourth sliding groove 304. Moreover, under the limiting sliding action of the fourth sliding protrusion 907, it can prevent the second abutting column 905 from rotating during the sliding process. A pressing plate 906 is fixedly connected to the outer wall on the side of the second abutting column 905 away from the push column 9. The pressing plate 906 is an "L"-shaped plastic plate. A fourth rotating groove 908 is formed in the outer wall on the side of the second abutting column 905 away from the pressing column. The fourth rotating groove 908 is a groove in the shape of a "convex". A fourth rotating protrusion 909 is rotatably connected to the inner wall of the fourth rotating groove 908. The fourth rotating protrusion 909 is a metal cylinder in the shape of a "convex". Moreover, the outer wall contour of the fourth rotating protrusion 909 is adapted to the inner wall contour of the fourth rotating groove 908. Therefore, the fourth rotating protrusion 909 can rotate on the inner wall of the fourth rotating groove 908. The outer wall on the side of the fourth rotating protrusion 909 away from the second abutting column 905 is fixedly connected to one end of the cable 809 away from the shovel plate 808. When the rotating rod 803 rotates, it will drive the cable 809 to rotate. At this time, the fourth rotating protrusion 909 will rotate driven by the cable 809, which can prevent the cable 809 from being repeatedly rotated and stressed to generate metal fatigue and cause the cable 809 to break.

[0059] When the worker steps on the pressing plate 906 with his foot, it will drive the second abutting column 905 to slide along the inner wall of the third avoidance hole 208 towards the bottom of the third fixing plate 202, and the fourth sliding protrusion 907 will slide along the inner wall of the fourth sliding groove 304 towards the third fixing plate 202. Under the limiting action of the two fourth sliding protrusions 907, the second abutting column 905 can be prevented from rotating during the sliding process. As the second abutting column 905 slides, the inclined surface at the bottom end of the second abutting column 905 will abut against the inclined surface at one end of the first abutting column 903 close to the second abutting column 905, causing the first abutting column 903 to slide along the inner wall of the second sliding groove 207 towards the pushing column 9. And the inclined surface at the end of the first abutting column 903 away from the second abutting column 905 will abut against the inclined surface at the bottom end of the pushing column 9, causing the pushing column 9 to slide towards the fixed mold 1. The second sliding protrusion 902 will follow the pushing column 9 and slide along the inner wall of the third sliding groove 303 towards the fixed mold 1. The pushing column 9 will push the first rotating circular plate 6 to displace towards the fixed mold 1, and the second sliding hole 601 will slide out from the outer wall of the second limiting column 801. At this time, the rotating handle 605 can be rotated to finely adjust the first rotating circular plate 6 so that the first limiting column 406 is inserted into the second sliding hole 601. With the above structural settings, by stepping on the pressing plate 906, the first rotating circular plate 6 can be driven to displace. At the same time, under the limiting action of the third sliding protrusion 904 and the fourth sliding protrusion 907, the pushing column 9 and the second abutting column 905 can be respectively prevented from rotating during the sliding process, which affects the subsequent operations of the worker. Also, when stepping on the pressing plate 906, the cable 809 can be subjected to a tensile force, which provides convenience for the worker to perform demolding subsequently.

[0060] The working principle of the technical solution provided by the present invention is as follows:

[0061] During use, the worker first places the metal support plate 105 into the fixed mold 1, then pours the concrete mixture into the fixed mold 1, and then rotates the rotating handle 605 clockwise, driving the second limiting column 801 to rotate clockwise. The second rotating circular plate 8 rotates synchronously with the second limiting column 801, and further causes the rotating rod 803 to rotate clockwise. During this process, the rolling cylinder 804 continuously knocks on the two knocking columns 108 on the inner wall of the large-hole column 106, causing the large-hole column 106 to shake, and driving a plurality of small-hole columns 107 to shake. The vibration generated by the shaking of the large-hole column 106 and the small-hole columns 107 can discharge the air bubbles in the concrete mixture. At the same time, the shovel plate 808 rotates clockwise with the rotation of the rotating rod 803 with the screw connection of the movable buckle 806 as the center, and the convex outer wall thereof can roll flat the collapse generated at the top of the concrete mixture due to the discharge of air bubbles.

[0062] Next, rotate the rotating handle 605 counterclockwise. When the rolling cylinder 804 is still rotating on the rotating rod 803, the knocking column 108 continuously knocks on the inner wall of the large-hole column 106. At this time, the shovel plate 808 uses the centrifugal force generated by rotation to remove the excess concrete mixture. After the concrete mixture condenses, the worker steps on the pressing plate 906 with his foot, driving the second abutting column 905 to slide along the inner wall of the third avoidance hole 208 towards the bottom of the third fixing plate 202. The fourth sliding protrusion 907 slides along the inner wall of the fourth sliding groove 304 towards the third fixing plate 202. Under the limiting action of the two fourth sliding protrusions 907, the second abutting column 905 will not rotate when sliding. As the second abutting column 905 slides, the inclined surface at its bottom end abuts against the inclined surface at the closer end of the first abutting column 903, causing the first abutting column 903 to slide along the inner wall of the second sliding groove 207 towards the pushing column 9. The inclined surface at the end of the first abutting column 903 away from the second abutting column 905 abuts against the inclined surface at the bottom end of the pushing column 9, prompting the pushing column 9 to slide towards the fixed mold 1. The second sliding protrusion 902 follows the pushing column 9 and slides along the inner wall of the third sliding groove 303 towards the fixed mold 1.

[0063] The pushing column 9 pushes the first rotating circular plate 6 towards the second rotating protrusion 404. The linkage plate 602 follows the first rotating circular plate 6 and slides along the outer wall of the second connecting column 702. At this time, the tension spring 604 is deformed by the tension, and the second sliding hole 601 slides out from the outer wall of the second limiting column 801. Rotate the rotating handle 605 slightly to adjust the first rotating circular plate 6 so that the second sliding hole 601 is sleeved on the outer wall of the first limiting column 406. Then rotate the rotating handle 605 clockwise. The first rotating circular plate 6 drives the second connecting circular plate 403 to rotate clockwise. The threaded column 402 rotates with the second connecting circular plate 403, and the threaded barrel 5 displaces towards the first rotating protrusion 4. The abutting cylinder 503 moves with the threaded barrel 5 and abuts against the bottom outer wall of the metal support plate 105, pushing the metal support plate 105 together with the condensed concrete mixture out of the fixed mold 1. Finally, the worker transports the metal support plate 105 and the concrete mixture to a spacious place for drying, places a new metal support plate 105, and repeats the above operations.
