Description

Technical Field

[0001] This utility model relates to the field of permeable brick production, and in particular to a sand-based permeable brick forming and pressing device. Background Technology

[0002] Sand-based permeable bricks are a type of building material made from sand. They are formed by extrusion molding using a non-sintering process, and have the functions of water permeability and filtration. They are energy-saving and environmentally friendly. They can permeate water by changing the surface tension of water. The dense surface solves the contradiction between strength and permeability, making sand-based permeable materials high in strength and fast in water permeability. They are also not easily clogged by dust and have long-lasting permeability. Existing sand-based permeable bricks generally rely on hydraulic equipment to push the upper mold downward to press the sand-based permeable brick raw materials in the lower mold into shape.

[0003] The sides of the formed permeable bricks are relatively rough. Therefore, when the permeable bricks are pushed upwards to demold, the side walls of the mold will be scratched. Over time, this increases the roughness of the mold sides, which may affect the demolding process later. It will also increase the gap between the upper and lower molds, causing some raw materials to be squeezed out from the gap between the upper and lower molds and causing the upper and lower molds to jam. It will also affect the thickness of the formed permeable bricks. In addition, since most existing molds are formed in one piece, the mold for the permeable bricks in individual positions cannot be replaced. Only the entire mold can be replaced, which further increases the maintenance cost. Utility Model Content

[0004] The purpose of this invention is to provide a sand-based permeable brick molding and pressing device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A sand-based permeable brick molding and pressing device includes a frame, a hydraulic oil station fixed on the front side of the frame, a conveying mechanism located on one side inside the frame, a molding mechanism and a demolding mechanism, a demolding mechanism located on the other side inside the frame, and a molding mechanism located above the demolding mechanism.

[0007] The forming mechanism includes a hydraulic cylinder, an upper mold is fixed to the telescopic part of the hydraulic cylinder, and pushers are fixed to both the front and rear sides of the upper mold. A spring is fixed to one end of the pusher that extends out of the frame.

[0008] The demolding mechanism includes a mold support plate, with multiple mold fixing seats on the top of the mold support plate. A fixing plate is provided on the upper side of the mold support plate, and the fixing plate has openings for the extension of the multiple mold fixing seats. Each mold fixing seat has two short side plates and two long side plates hinged to its upper end. Each mold fixing seat has a pusher seat slidably connected to its center. A pusher plate is provided at the bottom of the mold support plate, and the lower ends of the multiple pusher seats are fixed to the top of the pusher plate. Two lifting cylinders are provided on both sides of the pusher plate.

[0009] Preferably, the hydraulic cylinder fixing part is fixedly connected to the top of the frame, and the front and rear sides of the frame are provided with sliding grooves.

[0010] Preferably, the lifting cylinder fixing part is fixedly connected to the bottom of the frame, and the lifting cylinder telescopic part is fixedly connected to the fixing plate.

[0011] Preferably, the mold support plate has through holes on both sides for the extension and retraction parts of the lifting cylinder to pass through, and the mold support plate and multiple mold fixing seats have rectangular holes for the pusher seat to slide.

[0012] Preferably, the front and rear sides of the brick pusher are fixed with lugs for fixing the lower end of the spring.

[0013] Preferably, the two short side plates are located at the two short sides of the mold fixing base, and the two long side plates are located at the two long sides of the mold fixing base.

[0014] Preferably, the conveying mechanism includes a drive roller, both ends of which are rotatably connected to the inside of the frame. Multiple horizontal auxiliary rollers are provided on one side of the drive roller, and both ends of each auxiliary roller are rotatably connected to the inside of the frame. A conveyor belt is sleeved on the outside of the drive roller and the multiple auxiliary rollers, and a conveyor motor is fixedly installed at the input end of the drive roller.

[0015] The beneficial effects compared with the existing technology are as follows: by moving the fixed plate upward, the two short side plates and two long side plates on the mold fixing seat are closed to form a concave lower mold. In addition, the permeable brick is pressed into shape by the cooperation of the upper mold and the concave lower mold. At the same time, the upper mold moves upward to drive the pusher plate through the pusher and spring to move multiple pusher seats upward, thereby pushing out the formed permeable brick and separating the two short side plates and two long side plates from the side of the permeable brick, reducing the friction between the dehydrated brick and the mold.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-10 As shown, a sand-based permeable brick molding and pressing device includes a frame 4, a hydraulic oil station 5 fixed on the front side of the frame 4, a conveying mechanism 3 located on one side inside the frame 4, a molding mechanism 1 and a demolding mechanism 2, a demolding mechanism 2 located on the other side inside the frame 4, and a molding mechanism 1 located on the upper side of the demolding mechanism 2.

[0032] In this embodiment: the molding mechanism 1 includes a hydraulic cylinder 11, the upper mold 12 is fixed to the telescopic part of the hydraulic cylinder 11, and the upper mold 12 is fixed to the front and rear sides of the upper mold 12. The end of the pusher 13 extending out of the frame 4 is fixed to a spring 14. In this embodiment: the fixed part of the hydraulic cylinder 11 is fixedly connected to the top of the frame 4. The front and rear sides of the frame 4 are provided with sliding grooves. The upper mold 12 is pushed downward by the telescopic part of the hydraulic cylinder 11. The demolding mechanism 2 cooperates with the downward movement of the upper mold 12 to complete the pressing process of the permeable brick. At the same time, the pusher 13 pushes the spring 14 downward to compress.

[0033] In this embodiment: the demolding mechanism 2 includes a mold support plate 21, the top of the mold support plate 21 is provided with a plurality of mold fixing seats 24, the upper side of the mold support plate 21 is provided with a fixing plate 25, the fixing plate 25 is provided with a sleeve for the plurality of mold fixing seats 24 to extend out, the upper end of each mold fixing seat 24 is hinged with two short side plates 22 and two long side plates 23, the two short side plates 22 are located at the two short sides of the mold fixing seat 24, the two long side plates 23 are located at the two long sides of the mold fixing seat 24, each mold fixing seat 24 is slidably connected to a pusher seat 26 at its center, the bottom of the mold support plate 21 is provided with a pusher plate 27, and the lower end of the plurality of pusher seats 26 All are fixed to the top of the pusher plate 27. The pusher plate 27 has lugs on the front and rear sides for fixing the lower end of the spring 14. Two lifting cylinders 28 are provided on both sides of the pusher plate 27. The fixed part of the lifting cylinder 28 is fixedly connected to the bottom of the frame 4. The telescopic part of the lifting cylinder 28 is fixedly connected to the fixed plate 25. The mold support plate 21 has through holes on both sides for the telescopic part of the lifting cylinder 28 to pass through. The mold support plate 21 and multiple mold fixing seats 24 have rectangular holes for the pusher seat 26 to slide. The telescopic parts of the four lifting cylinders 28 push the fixed plate 25 upward, and the multiple sleeve sides on the fixed plate 25 push each mold fixing seat. The two short side plates 22 and two long side plates 23 on mold 24 flip over, causing the two short side plates 22 and two long side plates 23 on each mold fixing seat 24 to close together to form a concave structure. At this time, the mixed base material and colored coated sand are put into the concave structure. Then, the upper mold 12 moves downward to cooperate with the concave structure to press the permeable brick. Subsequently, the upper mold 12 moves upward and drives the pusher 13 to move synchronously. When the upper mold 12 disengages from the concave structure formed by the short side plates 22, long side plates 23 and mold fixing seat 24, the spring 14 is at its normal length. Then, the extension and retraction parts of the four lifting cylinders 28 drive the fixing plate 25 to move downward, so that the fixing plate 25... The sleeve opening is located on the lower side of the two short side plates 22 and the two long side plates 23. At this time, as the upper mold 12 continues to move upward, the spring 14 is stretched upward by the pusher 13. The spring 14 will drive the pusher plate 27 to move upward along the slide. Then the pusher plate 27 will push multiple pusher seats 26 to extend upward along the rectangular hole. Subsequently, the permeable brick after molding will be lifted upward by the multiple pusher seats 26. During this process, the short side plates 22 and long side plates 23 on the mold fixing seat 24 will detach from the support of the permeable brick side and flip and separate from each other, thereby completing the rapid demolding operation of the permeable brick and further reducing the scratching and wear between the permeable brick and the mold during demolding.

[0034] In this embodiment: the conveying mechanism 3 includes a drive roller 34, both ends of which are rotatably connected to the inside of the frame 4. A plurality of horizontal auxiliary rollers 31 are provided on one side of the drive roller 34. Both ends of each auxiliary roller 31 are rotatably connected to the inside of the frame 4. A conveyor belt 32 is sleeved on the outside of the drive roller 34 and the plurality of auxiliary rollers 31. A conveyor motor 33 is fixedly provided at the input end of the drive roller 34. The drive roller 34 is rotated by the rotating part of the conveyor motor 33. The rotation of the drive roller 34 drives the conveyor belt 32 to rotate outside the auxiliary rollers 31, thereby conveying the permeable bricks after they are formed.

[0035] Working Principle: In operation, the four lifting cylinders 28 first use their telescopic parts to push the fixed plate 25 upwards. This, in turn, pushes the two short side plates 22 and two long side plates 23 on each mold fixing seat 24 to flip through the multiple sleeve sides of the fixed plate 25. This causes the two short side plates 22 and two long side plates 23 on each mold fixing seat 24 to close together, forming a concave structure. At this point, the mixed base material and colored coated sand are poured into the concave structure. Then, the hydraulic cylinder 11 uses its telescopic part to push the upper mold 12 downwards. As the upper mold 12 moves downwards and engages with the concave structure, the base material and colored coated sand within the concave structure are pressed to form permeable bricks. Subsequently, the hydraulic cylinder 11's telescopic part drives the upper mold 12 upwards, and the pusher 13 moves synchronously with the upper mold 12. When the upper mold 12 disengages from the concave structure formed by the short side plates 22, long side plates 23, and mold fixing seat 24, the spring 14 is at its normal length. Then, the four lifting cylinders 28's telescopic parts... The moving fixed plate 25 moves downward, so that the fixed plate 25 is located under the two short side plates 22 and the two long side plates 23. At this time, as the upper mold 12 continues to move upward, the spring 14 is stretched upward by the pusher frame 13. The spring 14 will drive the brick pusher plate 27 to move upward along the slide groove. Then the brick pusher plate 27 will push multiple brick pusher seats 26 to extend upward along the rectangular hole. Subsequently, the multiple brick pusher seats 26 push the formed permeable brick upward. During this process, the short side plates 22 and long side plates 23 on the mold fixed seat 24 will detach from the support of the permeable brick side and flip and separate from each other, thereby completing the rapid demolding operation of the permeable brick. This can further reduce the scratching and wear between the permeable brick and the mold during demolding. Then, the permeable brick can be placed on the conveyor belt 32 by the gripping device. The rotating part of the conveyor motor 33 drives the drive roller 34 to rotate. The rotation of the drive roller 34 drives the conveyor belt 32 to rotate outside the auxiliary roller 31, thereby conveying the formed permeable brick.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
