Description

Technical Field

[0001] This invention relates to the field of porous brick processing technology, and in particular to a porous brick production mold. Background Technology

[0002] Porous bricks are a new type of wall material, including concrete porous bricks. They are made with cement as a binder and sand, stone, and other aggregates as the main materials, through mixing with water, molding, and curing. They have a multi-row pore structure. During production, they can utilize some industrial waste, reducing reliance on natural resources, lowering energy consumption, and providing good environmental benefits. Simultaneously, their multi-row pore structure gives them certain thermal insulation properties, helping to improve the building's thermal environment and reduce energy consumption, making them a relatively ideal wall material choice.

[0003] In the current production process of porous bricks, the prepared concrete mixture is first poured into a mold, and then a vibrator is inserted to remove air bubbles through vibration. After the concrete mixture has hardened, the bricks are demolded and placed in the sun to dry. However, the perforated columns in the porous brick production mold can prevent the vibrator from penetrating the concrete mixture, making it difficult for air bubbles to be fully expelled. Therefore, production workers usually tap around the mold to shake out internal air bubbles. However, because it is difficult to maintain uniform tapping force, this not only easily generates new air bubbles, affecting the production quality of porous bricks, but may also damage the mold.

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

[0005] The technical problem this invention aims to solve is to provide a porous brick production mold. By incorporating a rotating component, the mold not only strikes the inner wall of the large-hole column during rotation, causing the large-hole column to drive the small-hole column to shake, but also utilizes the vibration generated by the combined action to expel air bubbles from the concrete mixture within the fixed mold. Simultaneously, it flattens the top of the mixture caused by the expulsion of air bubbles. Furthermore, adjusting the rotation direction of the rotating component allows for the removal of excess concrete mixture. Moreover, after the concrete mixture has solidified, the rotating component can be used to push it out of the fixed mold, achieving rapid demolding and facilitating workers to transport it to a spacious area for drying. These features effectively solve the problem of air bubbles in the concrete mixture affecting production quality.

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

[0018] In the above solution, by providing the rotating assembly, the knocking post on the inner wall of the large hole column can be knocked during rotation, 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 air bubbles from the concrete mixture in the fixed mold, and at the same time, the collapse generated on the top of the mixture due to air bubble discharge is rolled flat; and by adjusting the rotation direction of the rotating assembly, excess concrete mixture can also be removed. In addition, after the concrete mixture is condensed, 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.

[0019] By providing the threaded post, the threaded cylinder, the first connecting post, the abutting cylindrical post and the metal support plate, the threaded post can rotate synchronously with the second connecting circular plate by rotating the second connecting circular plate clockwise, which further drives the abutting cylindrical post to displace along the threaded cylinder on the outer wall of the threaded post, and push the concrete mixture out of the fixed mold. In this way, workers can quickly perform demolding operation on the condensed concrete mixture and carry it to a spacious place for drying.

[0020] By setting a second rotating disc, a second limiting post, a rotating rod, a rolling cylinder, and a shovel, the rotating handle can be rotated. During the rotation of the rotating rod, the rolling cylinder continuously strikes the two striking posts 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 dislodge air bubbles in the concrete mixture. At the same time, the shovel can flatten the collapse caused by the dislodgement of air bubbles on the top of the concrete mixture. In addition, by rotating the rotating handle in the opposite direction, the shovel can use the centrifugal force generated by the rotation to remove excess concrete mixture.

[0021] By setting up a push column, a first abutment column, a third sliding protrusion, a second abutment column, a Z-shaped fixing plate, and a pressing plate, the first rotating circular plate can be displaced by stepping on the pressing plate. At the same time, under the limiting action of the third and fourth sliding protrusions, the push column and the second abutment column are prevented from rotating during the sliding process, which would affect the subsequent operation of the workers. Furthermore, when the pressing plate is stepped on, the cable is subjected to tension, which provides convenience for the workers to demold later. Attached Figure Description

[0049] like Figures 1 to 18As shown, 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 formed by four rectangular plastic plates. Supporting protrusions 101 are symmetrically fixed to both sides of the bottom outer wall of the fixed mold 1. The supporting protrusions 101 are plastic cuboids. Slots 102 are symmetrically formed on the outer walls of the supporting protrusions 101 near the bottom. The slots 102 are rectangular grooves. First elastic plates 109 are respectively fixed to the outer walls of the two supporting protrusions 101 near the central axis of the fixed mold 1. The first elastic plates 109 consist of plastic plates with "C"-shaped ends and a straight plastic plate in the middle. When the first elastic plate 109... 9. Under stress, it will deform along its bending direction. First clearance grooves 103 are respectively provided on the inner walls of the fixed mold 1 on both sides near the first elastic plate 109. The first clearance grooves 103 are rectangular grooves. A mold base plate 104 is slidably connected to the inner wall of the fixed mold 1. The mold base plate 104 is a rectangular plastic plate. The outer contour of the mold base plate 104 matches the inner contour of the first clearance grooves 103, so the mold base plate 104 can swing on the inner wall of the fixed mold 1. A large-hole column 106 and several small-hole columns 107 are fixedly connected to the top outer wall of the mold base plate 104. The large-hole column 106 is a hollow plastic cylinder, and the small-hole columns 107... 7 is a plastic cylinder. A striking post 108 is symmetrically fixedly connected to the inner wall of the large-hole post 106. The striking post 108 is a semi-circular plastic cylinder. Four first clearance holes 111 arranged in a circular array are provided on the bottom outer wall of the mold base plate 104. The first clearance holes 111 are circular grooves that provide clearance space for the shaking of the mold base plate 104. Two limiting cylinders 110 are fixedly connected to the middle of the bottom outer wall of the mold base plate 104. The limiting cylinders 110 are plastic cylinders. When the mold base plate 104 shakes, the limiting cylinders 110 will move along with the mold base plate 104. At this time, the limiting cylinders 110... The outer wall of the mold plate 104 will abut against the middle outer wall of the first elastic plate 109, causing the two ends of the first elastic plate 109 to be stressed and deformed along its bending direction. Then, under the action of the elasticity of the first elastic plate 109 itself, it will recover its deformation and push the limiting cylinder 110 to reset. In this way, with the cooperation of the two first elastic plates 109 and the two limiting cylinders 110, the mold base plate 104 can shake better, and after the shaking is over, the mold base plate 104 can be reset, which is convenient for subsequent operations by workers. The rotating component can generate vibration by rotating to expel air bubbles in the concrete mixture in the fixed mold 1. The rotating component is connected to the fixed mold 1.

[0050] This application, by setting up a rotating component, can not only strike the striking column 108 on 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, but also use the vibration generated by the two to expel air bubbles in the concrete mixture in the fixed mold 1. At the same time, it can flatten the collapse caused by the expulsion of air bubbles on the top of the mixture. Moreover, by adjusting the rotation direction of the rotating component, excess concrete mixture can also be removed. In addition, after the concrete mixture has solidified, it can be pushed out of the fixed mold 1 with the help of the rotating component, making it convenient for workers to carry it to a spacious place to dry.

[0051] As one implementation method in this embodiment, such 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 contour of the end of the U-shaped fixing plate 112 near the fixing mold 1 matches the inner contour of the slot 102, so 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 fixing mold 1 can be fixed to the top of the first fixing plate 2 by screws using the U-shaped fixing plate 112. A second fixing plate 201 is fixedly connected to the outer side of the first fixing plate 2. The first fixing plate 2 is a rectangular metal plate, and a second fixing plate 201 is fixedly connected to the middle position of the top outer wall of the first fixing plate 2. A metal cylinder is attached to the first fixing plate 2. A first circular groove 204 is formed on the top outer wall of the first fixing plate 2. The first circular groove 204 is a circular groove. The second fixing plate 201 is a U-shaped metal plate. A third fixing plate 202 is fixedly connected to the end of the second fixing plate 201 away from the first fixing plate 2. The third fixing plate 202 is a U-shaped metal plate. The cooperation of the first fixing plate 2, the second fixing plate 201 and the third fixing plate 202 can provide support for fixing the mold 1. A first rotating groove 205 is formed in the middle of the bottom outer wall of the first fixing plate 2. The first rotating groove 205 is a circular groove with a convex cross-section. Four second clearance holes 203 are formed in a circumferential array on the top outer wall of the first fixing plate 2. The second clearance hole 203 is a circular groove. The second clearance hole 203 is the same size and position as the first clearance hole 111 mentioned above. A first connecting circular plate 401 is rotatably connected to the inner wall of the first rotating groove 205. The first connecting circular plate 401 is a plastic circular plate. 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 contour of the first rotating protrusion 4 matches the inner 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 post 402 is fixedly connected to the bottom outer wall of the first connecting circular plate 401. The threaded post 402 is a plastic cylinder with a threaded groove on its outer wall. A second connecting circular plate 403 is fixedly connected to the end of 402 away from the first connecting circular plate 401. The second connecting circular plate 403 is a plastic circular plate. Several first limiting posts 406 arranged in a circumferential array are fixedly connected to the bottom outer wall of the second connecting circular plate 403. The first limiting posts 406 are plastic cylinders with an arc at one 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 circular groove 405 is opened on the bottom outer wall of the second rotating protrusion 404. The second circular groove 405 is a circular groove and extends through the top outer wall of the first rotating protrusion 4. A threaded cylinder 5 is screwed onto the outer wall of the threaded post 402. The threaded cylinder 5 is a plastic cylinder.A threaded hole 501 is formed on the outer wall of the top end of the threaded cylinder 5. The threaded hole 501 is a slot with a threaded groove. The inner contour of the threaded hole 501 matches the outer contour of the threaded post 402, so the threaded cylinder 5 can rotate on the outer wall of the threaded post 402.

[0052] Four first connecting posts 502 arranged in a circular array are fixedly connected to the outer wall of the threaded cylinder 5. Each connecting post is a plastic cuboid with one end curved. An abutting cylinder 503 is fixedly connected to the top of the first connecting post 502 away from the outer wall of the threaded cylinder 5. The abutting cylinder 503 is also a plastic cylinder with one end curved, and its outer wall contour is adapted to the inner wall contour of the first clearance hole 111 and the second clearance hole 203 mentioned above. Therefore, the end of the abutting cylinder 503 away from the first connecting post 502 can pass through the second clearance hole 203 and the first clearance hole in sequence. 111, and slides on its inner wall. A sliding column 504 is fixedly connected to the outer wall of the threaded cylinder 5 near the second fixed plate 201. The sliding column 504 consists of two parts: a plastic cylinder and a plastic circular plate. 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 opened on the middle outer wall of the second fixed plate 201, the first sliding groove 206 is a rectangular groove with arcs at both ends. The inner wall contour of the first sliding groove 206 matches 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 subjected to its... The sliding column 504 can limit the rotation of the threaded column 402, thus preventing the threaded cylinder 5 from rotating with the threaded column 402. The worker first places the metal pallet 105 into the fixed mold 1. The outer contour of the metal pallet 105 matches the inner contour of the fixed mold 1, and the outer wall of the metal pallet 105 has circular grooves that match the large-hole column 106 and the small-hole column 107. Then, the concrete mixture can be poured into the fixed mold 1. After the concrete mixture has solidified, the second connecting circular plate 403 can be rotated clockwise. 403 will cause the threaded column 402 to rotate. At this time, the threaded cylinder 5 will move in the direction of the first rotating protrusion 4. The abutting cylinder 503 will move with the threaded cylinder 5 and abut against the bottom outer wall of the metal support plate 105, pushing the metal support plate 105 to slide towards the top of the fixed mold 1, pushing the solidified concrete mixture out of the fixed mold 1. With the above structure, the concrete mixture can be pushed out of the fixed mold 1 by rotating the second connecting circular plate 403 clockwise, which makes it easy for workers to quickly demold the solidified concrete mixture and transport it to a spacious place to dry.

[0053] In this embodiment, as Figures 7 to 14As shown, 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, and a first disc 701 and a second disc 703 are fixedly connected to both ends of the rotating cylinder 7, respectively. Both the first disc 701 and the second disc 703 are plastic discs, and their diameters are larger than the diameter of the rotating cylinder 7. A second rotating groove 704 is formed on the top outer wall of the first disc 701. The second rotating groove 704 is a cylindrical groove with a "convex" shape, and the inner wall contour of the second rotating groove 704 matches 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 rotating the rotating cylinder 7 will not affect the second connecting disc 403. A third rotating groove 705 is formed on the bottom outer wall of the second disc 703. The third rotating groove 705 is a cylindrical groove with a "convex" shape. A third circular hole groove 706 is formed on the bottom inner wall of the second rotating groove 704. The third circular hole groove 706 is a circular groove and extends through the top inner wall of the third rotating groove 705. One end of two second connecting posts 702 is fixedly connected to the bottom outer wall of the first disc 701. The other ends of the two second connecting posts 702 are fixedly connected to the top outer wall of the second disc 703. The two second connecting posts 702 are symmetrical about the rotating cylinder 7. A linkage plate 602 is slidably connected to the outer wall of the two second connecting posts 702. The linkage plate 602 is a rectangular plastic plate with an arc at one end. Two linkage plates 602 are each fixedly connected to a first rotating circular plate 6 at the end furthest from the rotating cylinder 7. The first rotating circular plate 6 consists of two hollow plastic circular plates, with the outer hollow plastic circular plate being thinner than the inner hollow plastic circular plate. A first sliding hole 603 is provided on the top outer wall of the linkage plate 602. The first sliding hole 603 is a circular groove, and the inner wall contour of the first sliding hole 603 matches the outer wall contour of the second connecting column 702. Therefore, the linkage plate 602 can slide on the outer wall of the second connecting column 702, and rotating the first rotating circular plate 6 will cause the rotating cylinder 7 to rotate. One end of a tension spring 604 is fixedly connected to the bottom outer wall of the linkage plate 602, and the other end of the tension spring 604 is fixedly connected to the top of the second disc 703. The tension spring 604 on the outer wall is prior art and will not be described in detail. When the linkage plate 602 slides along the outer wall of the second connecting post 702 toward the second rotating protrusion 404, the tension spring 604 will be subjected to tension and deform along its bending direction. When the tension spring 604 is no longer under force, it will pull the linkage plate 602 to reset. Several second sliding holes 601 are provided on the outer wall of the first rotating circular plate 6 near the linkage plate 602 in a circumferential array. The second sliding holes 601 are circular grooves. The inner walls of the second sliding holes 601 near the top and bottom of the first rotating circular plate 6 are respectively provided with rounded corners, and the inner wall contour of the second sliding holes 601 is adapted to the outer wall contour of the first limiting post 406.This facilitates the insertion of the first limiting post 406 into the second sliding hole 601. Four rotating handles 605 arranged in a circular array are fixedly connected to the outer wall of the first rotating circular plate 6. Each rotating handle 605 consists 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 rotating handles 605 facilitate the worker's rotation of the first rotating circular plate 6. A fifth sliding groove 606 is provided on the bottom outer wall of the first rotating circular plate 6. The fifth sliding groove 606 is a convex annular groove. When the first rotating circular plate 6 is pushed towards the second rotating protrusion 404, the linkage plate 602 will follow the first rotating circular plate. Plate 6 slides along the outer wall of the second connecting post 702. At this time, the tension spring 604 is under tension and deforms along its bending direction. The second sliding hole 601 fits onto the outer wall of the first limiting post 406. Then, the rotating handle 605 can be rotated clockwise. The first rotating circular plate 6 will drive the second connecting circular plate 403 to rotate clockwise. This structural arrangement allows the second connecting circular plate 403 to rotate by rotating the rotating handle 605, causing the threaded post 402 to rotate along with the second connecting circular plate 403. This, in turn, causes the aforementioned abutting post 503 to move along with the threaded cylinder 5 on the outer wall of the threaded post 402, facilitating 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 "convex"-shaped plastic block, and the outer wall contour of the third rotating protrusion (802) is adapted to the inner wall contour of the third rotating groove (705), so that the third rotating protrusion (802) can rotate on the inner wall of the third rotating groove (705). A second rotating circular plate (8) is fixedly connected to the bottom of the third rotating protrusion (802), and the second rotating circular plate (8) is a circular plastic plate. A fourth circular hole groove (810) is opened on the top outer wall of the third rotating protrusion (802), the fourth circular hole groove (810) is a circular groove body and penetrates through the bottom outer wall of the second rotating circular plate (8), and the inner wall contour of the fourth circular hole groove (810) is adapted to the outer wall contour of the pull cable (809), so that the pull cable (809) can pass through the inner wall of the fourth circular hole groove (810). A plurality of second limiting posts (801) are fixedly connected to the top outer wall of the second rotating circular plate (8), the second limiting posts (801) are plastic cylinders with radian at one end, and the outer wall contour of the second limiting posts (801) is adapted to the inner wall contour of the second sliding hole (601). In combination with the rounded corner arranged on the inner wall of the bottom end of the first rotating circular plate (6) of the second sliding hole (601) mentioned above, the second limiting posts (801) can be conveniently inserted into the second sliding hole (601). When the rotating handle (605) is rotated, it will drive the second limiting posts (801) to rotate, and drive the second rotating circular plate (8) to rotate. A rotating rod (803) is fixedly connected to the top outer wall of the third rotating protrusion (802), the rotating rod (803) is a hollow metal cylinder, and 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), so that the end of the rotating rod (803) away from the third rotating protrusion (802) can sequentially 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) and rotate. The end of the rotating rod (803) away from the third rotating protrusion (802) is formed into an "n" shape, and circular grooves are respectively opened at two turning positions of the rotating rod (803) close to the "n" shape, which are respectively communicated with the inner wall of the rotating rod (803). A rolling cylinder (804) is sleeved on the "n"-shaped outer wall of the rotating rod (803), the rolling cylinder (804) is a hollow plastic cylinder, and the inner wall contour of the rolling cylinder (804) is adapted to the outer wall contour of the rotating rod (803), so that 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 the two knocking posts (108), so that the large-hole post (106) shakes.

[0055] An active buckle 806 is fixedly connected to an end of the rotating rod 803 away from the third rotating protrusion 802. The active buckle 806 is a U-shaped metal plate. The active buckle 806 is screwed with a screwing plate 807 through a screw. The screwing plate 807 consists of three parts: plastic circular plates at two ends and a plastic cylinder at the middle part. A shovel plate 808 is fixedly connected to an outer wall of an end of the screwing plate 807 away from the active buckle 806. The shovel plate 808 is a plastic plate with a radian. By adjusting and rotating the rotation direction of the rotating rod 803, the shovel plate 808 can not only shovel off excess concrete mixture in the fixed mold 1, but also roll the uneven concrete mixture in the fixed mold flat. A second elastic plate 805 is fixedly connected to an outer wall of the screwing plate 807 close to the shovel plate 808. The second elastic plate 805 is a C-shaped metal plate, and deforms along its bending direction after being stressed. A pull cable 809 is fixedly connected to an outer wall of an end of the screwing plate 807 close to the active buckle 806. The pull cable 809 is disclosed in the prior art, and thus will not be described in detail. The outer wall contour of the pull cable 809 is adapted to the inner wall contour of the rotating rod 803 and the inner wall contour of the fourth circular hole groove 810 respectively. Therefore, the other end of the pull cable 809 passes through the top end of the rotating rod 803 first, then passes out from a turning position close to the top of the n-shaped portion on the rotating rod 803, then passes into the inner wall of the rotating rod 803 from a turning position close to the bottom of the n-shaped portion on the rotating rod 803, and then passes out from the fourth circular hole groove 810. When the pull cable 809 is pulled, the screwing plate 807 can rotate with the screwing position as a center, so that the shovel plate 808 remains parallel to the pulling rod, which is convenient for workers to place the metal support plate 105 into the fixed mold 1, and is also convenient for workers to take the condensed concrete mixture off the fixed mold 1.

[0056] When the cable 809 is no longer pulled, the second elastic plate 805 is no longer under force and will recover its deformation along the bending direction, causing the shovel plate 808 to return to its original position. When the rotating handle 605 is rotated clockwise, the second limiting post 801 will rotate clockwise, and the second rotating circular plate 8 will rotate with the second limiting post 801. At this time, the rotating rod 803 will rotate clockwise, and the rolling cylinder 804 will continuously strike the two striking posts 108 on the inner wall of the large hole post 106 during the rotation of the rotating rod 803, causing the large hole post 106 to shake, which in turn causes several small hole posts 107 to shake. The vibration generated by the shaking of the large hole post 106 and the small hole posts 107 can dislodge air bubbles in the concrete mixture. The shovel plate 808 will rotate clockwise with the rotation of the rotating rod 803, with the screw connection of the movable buckle 806 as the center. At this time, the protruding outer wall of the shovel plate 808 can dislodge air bubbles from the top of the concrete mixture. The collapse caused by the discharge is flattened. When the rotating handle 605 is rotated counterclockwise, the rolling drum 804 will continue to strike the two striking columns 108 on the inner wall of the large-hole column 106 during the rotation of the rotating rod 803. The shovel plate 808, in conjunction with the centrifugal force generated by the rotation, will remove the excess concrete mixture. The above structure can be configured so that by rotating the rotating handle 605, the rolling drum 804 will continuously strike the two striking columns 108 on the inner wall of the large-hole column 106 during the rotation of the rotating rod 803, causing the large-hole column 106 to shake and drive 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 shake out the air bubbles in the concrete mixture. At the same time, the shovel plate 808 can flatten the collapse caused by the discharge of air bubbles on the top of the concrete mixture. In addition, by rotating the rotating handle 605 in the opposite 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 third fixing plate 202 near the second fixing plate 201. The second sliding groove 207 is a straight groove in the shape of a "convex" shape. A third clearance hole 208 is formed on the outer wall of the top of the third fixing plate 202 near one end of the second sliding groove 207. The third clearance hole 208 is a square slot. First connecting plates 3 are symmetrically fixedly connected to the outer walls of the top of the third fixing plate 202 near both sides of the second sliding groove 207. The first connecting plates 3 are rectangular metal plates. A Z-shaped fixing plate 301 is fixedly connected to the end of the first connecting plate 3 away from the third fixing plate 202. The Z-shaped fixing plate 301 is a metal plate in the shape of a "Z". Third sliding grooves 303 are formed on the outer walls of the Z-shaped fixing plate 301 near both ends. The fourth sliding groove 304, the third sliding groove 303, and the fourth sliding groove 304 are all rectangular grooves with arc-shaped ends. The third sliding groove 303 and the fourth sliding groove 304 are symmetrical about the center of the Z-shaped fixing plate 301. The third sliding groove 303 is farther away from the third fixing plate 202 than the fourth sliding groove 304. The Z-shaped fixing plate 301, which is farther away from the second frame, has a fourth clearance hole 302 on its outer wall near the middle. The fourth clearance hole 302 is a circular groove, and the inner wall contour of the fourth clearance hole 302 matches the outer wall contour of the cable 809. Therefore, the cable 809 can pass through the fourth clearance hole 302. The inner wall of the fifth sliding groove 606 is slidably connected to a push post 9, which is a plastic material with an inclined bottom. A cylindrical push column 9 has a first sliding protrusion 901 fixedly connected to its top. The first sliding protrusion 901 is a convex-shaped plastic block. The outer contour of the first sliding protrusion 901 matches the inner contour of the fifth sliding groove 606, so the first sliding protrusion 901 can slide on the inner wall of the fifth sliding groove 606. A second sliding protrusion 902 is symmetrically fixedly connected to the outer wall of the push column 9. The second sliding protrusion 902 consists of a plastic cuboid with curved ends and a plastic circular plate. The outer contour of the plastic cuboid on the second sliding protrusion 902 matches the inner contour of the third sliding groove 303, so the second sliding protrusion 902 can slide on the inner wall of the third sliding groove 303. The inner wall of the second sliding groove 207... A first abutment post 903 is slidably connected to the upper part of the first abutment post 903. The first abutment post 903 is an isosceles trapezoidal post made of plastic. A third sliding protrusion 904 is fixedly connected to the bottom outer wall of the first abutment post 903. The third sliding protrusion 904 is a "convex" shaped plastic post, and the outer contour of the third sliding protrusion 904 matches the inner 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 toward the pushing post 9, the first abutment post 903 will slide along with the third sliding protrusion 904. The inclined surface of the first abutment post 903 near the pushing post 9 will abut against the inclined surface at the bottom of the pushing post 9.The pushing column 9 drives the second sliding protrusion 902 to slide along the inner wall of the third sliding groove 303 away from the third fixed plate 202, and pushes the first rotating circular plate 6 to move towards the second rotating protrusion 404. Under the limiting sliding action of the third sliding protrusion 904, the pushing column 9 is prevented from rotating during the sliding process, thus avoiding affecting the pushing of the first rotating circular plate 6.

[0058] Two fourth sliding grooves 304 are slidably connected to their outer walls by fourth sliding protrusions 907. Each fourth sliding protrusion 907 consists of a plastic cuboid with curved ends and a plastic circular plate. The outer contour of the plastic cuboid on the fourth sliding protrusion 907 matches the inner contour of the fourth sliding groove 304, allowing the fourth sliding protrusion 907 to slide on the inner wall of the fourth sliding groove 304. One end of each of the two fourth sliding protrusions 907 is fixedly connected to the same second abutment post 905. The second abutment post 905 is a right-angled trapezoidal post made of plastic. The inclined surface of the second abutment post 905 faces the direction of the first abutment post 903, and the outer wall contour of the second abutment post 905 matches the inner wall contour of the third clearance hole 208. Therefore, the second abutment post 905 can slide into the third clearance hole 208. During the sliding process of the second abutment post 905, the inclined surface of the second abutment post 905 will abut against the inclined surface of the first abutment post 903, and push the first abutment post 903 to slide along the inner wall of the second sliding groove 207 towards the direction of the pushing post 9. The fourth sliding protrusion 907 will follow the second abutment post 905 along the inner wall of the fourth sliding groove 304. The wall slides, and under the limiting sliding action of the fourth sliding protrusion 907, the second abutment post 905 can be prevented from rotating during the sliding process. A pressing plate 906 is fixedly connected to the outer wall of the second abutment post 905 on the side away from the pushing post 9. The pressing plate 906 is an "L"-shaped plastic plate. A fourth rotating groove 908 is opened on the outer wall of the second abutment post 905 on the side away from the pressing post. The fourth rotating groove 908 is a "convex" shaped groove. 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 "convex" shaped metal cylinder. Furthermore, the outer contour of the fourth rotating protrusion 909 is adapted to the inner contour of the fourth rotating groove 908, so the fourth rotating protrusion 909 can rotate on the inner wall of the fourth rotating groove 908. The outer wall of the fourth rotating protrusion 909 away from the second abutment post 905 is fixedly connected to the 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 under the drive of the cable 809, which can avoid the cable 809 from being repeatedly rotated and subjected to force, resulting in metal fatigue and causing the cable 809 to break.

[0059] When the worker steps on the pressing plate 906, it causes the second abutment post 905 to slide along the inner wall of the third clearance 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. The limiting effect of the two fourth sliding protrusions 907 prevents the second abutment post 905 from rotating during sliding. As the second abutment post 905 slides, the inclined surface at the bottom of the second abutment post 905 abuts against the inclined surface at the end of the first abutment post 903 closest to the second abutment post 905, causing the first abutment post 903 to slide along the inner wall of the second sliding groove 207 towards the pushing post 9. Meanwhile, the inclined surface at the end of the first abutment post 903 furthest from the second abutment post 905 abuts against the inclined surface at the bottom of the pushing post 9, causing the pushing post 9 towards the fixed mold 1. When sliding occurs, the second sliding protrusion 902 will slide along the inner wall of the third sliding groove 303 towards the fixed mold 1, following the push column 9. The push column 9 will push the first rotating circular plate 6 to move towards the fixed mold 1. 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 make a fine adjustment to the first rotating circular plate 6, so that the first limiting column 406 is inserted into the second sliding hole 601. With the above structure, the first rotating circular plate 6 can be moved by pressing the pressing plate 906. At the same time, under the limiting action of the third sliding protrusion 904 and the fourth sliding protrusion 907, the push column 9 and the second abutting column 905 are prevented from rotating during the sliding process, which would affect the subsequent operation of the worker. When the pressing plate 906 is pressed, the cable 809 is subjected to tension, which provides convenience for the worker to demold later.

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

[0061] In use, the worker first places the metal pallet 105 into the fixed mold 1, then pours the concrete mixture into the fixed mold 1, and then rotates the rotating handle 605 clockwise, causing the second limiting post 801 to rotate clockwise. The second rotating circular plate 8 rotates synchronously with the second limiting post 801, thereby causing the rotating rod 803 to rotate clockwise. During this process, the rolling cylinder 804 continuously strikes the two striking posts 108 on the inner wall of the large hole post 106, causing the large hole post 106 to shake, and causing multiple small hole posts 107 to shake. The vibration generated by the shaking of the large hole post 106 and the small hole posts 107 can expel air bubbles in the concrete mixture. At the same time, the shovel plate 808 rotates clockwise with the rotating rod 803 around the screw connection of the movable buckle 806 as the center. Its raised outer wall can flatten the collapse caused by the expulsion of air bubbles on the top of the concrete mixture.

[0062] Next, the handle 605 is rotated counterclockwise. While the rotating rod 803 continues to rotate, the roller 804 continues to strike the striking post 108 on the inner wall of the large-hole post 106. At this time, the shovel plate 808 uses the centrifugal force generated by the rotation to remove excess concrete mixture. After the concrete mixture has solidified, the worker steps on the pressing plate 906, causing the second abutment post 905 to slide along the inner wall of the third clearance hole 208 towards the bottom of the third fixed plate 202. The fourth sliding protrusion 907 slides along the inner wall of the fourth sliding groove 304 towards the third fixed plate 202. Under the limiting effect of 907, the second abutment post 905 will not rotate when sliding. As the second abutment post 905 slides, its bottom inclined surface abuts against the inclined surface of the first abutment post 903, causing the first abutment post 903 to slide along the inner wall of the second sliding groove 207 towards the push post 9. The inclined surface of the first abutment post 903 away from the second abutment post 905 abuts against the bottom inclined surface of the push post 9, causing the push post 9 to slide towards the fixed mold 1. The second sliding protrusion 902 follows the push post 9 and slides along the inner wall of the third sliding groove 303 towards the fixed mold 1.

[0063] The pusher 9 pushes the first rotating circular plate 6 to slide 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 post 702. At this time, the tension spring 604 is subjected to tension and deforms. The second sliding hole 601 slides out from the outer wall of the second limiting post 801. The rotating handle 605 is rotated to finely adjust the first rotating circular plate 6 so that the second sliding hole 601 fits into the outer wall of the first limiting post 406. Then, the rotating handle 605 is rotated clockwise. The first rotating circular plate 6 drives the second connecting circular plate 403 to rotate clockwise. The threaded post 402 follows the second connecting circular plate 403 to rotate. The threaded cylinder 5 moves towards the first rotating protrusion 4. The abutting cylinder 503 moves with the threaded cylinder 5 and abuts against the bottom outer wall of the metal pallet 105. The metal pallet 105, together with the solidified concrete mixture, is pushed out of the fixed mold 1. Finally, the workers move the metal pallet 105 and the concrete mixture to a spacious place to dry. A new metal pallet 105 is placed, and the above operation is repeated.
