Description

A rapid prototyping equipment for preparing permeable bricks Technical Field

[0001] This invention relates to the field of permeable brick production technology, specifically to a rapid prototyping equipment for preparing permeable bricks. Background Technology

[0002] Permeable paving bricks are a new type of highly permeable pavement material, made from aggregates of a specific gradation, cement, special binders, and water through a special process and specialized equipment. Compared to ordinary concrete paving bricks, their biggest advantage is their high permeability coefficient.

[0003] When it rains, rainwater can seep into the ground through the paving bricks or be stored in the gaps between the bricks, reducing water accumulation on the road surface. Permeable concrete paving bricks can be widely used in courtyards, parks, squares, gardens, factory areas, parking lots, tree pits, greenhouses, pedestrian walkways, and light traffic roads. Permeable concrete paving bricks not only beautify the environment but also prevent the loss of precious water resources, offering positive social, environmental, and ecological benefits. The development and application of permeable concrete paving bricks has received high attention and welcome from relevant national departments and all sectors of society.

[0004] The production process of permeable bricks is mainly divided into two types: mold pressing and cutting. In the mold pressing process, a hydraulic press is often used as the power source. The lower mold is fixed on the frame. When demolding, the molded part is pushed out of the lower mold by a pushing mechanism set in the device and enters the surface of the frame. Since the molded part has not yet achieved a significant increase in strength, there is a risk of breakage during this process. In addition, the material fed into the lower mold from the hopper cannot be guaranteed to be uniform. Therefore, there is a phenomenon of uneven density in the pressed molded part, which ultimately affects the quality of the finished product.

[0005] Therefore, the purpose of this invention is to provide a rapid prototyping device for preparing permeable bricks that can solve the problem of breakage during demolding and prevent uneven material distribution in the lower mold. Summary of the Invention

[0006] To address the problems in existing technologies, this invention provides a rapid prototyping equipment for permeable brick manufacturing. This invention solves the problems of breakage during demolding and uneven material distribution within the lower mold, and provides a rapid prototyping equipment for permeable brick manufacturing.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a permeable brick preparation rapid prototyping equipment, including a frame, a hydraulic press fixed on the top of the frame, a movable plate fixed on the telescopic end of the hydraulic press, a worktable arranged directly below the movable plate, the worktable fixed on the side wall of the frame, four guide rods fixed inside the frame, and the movable plate and the worktable slidably connected to the guide rods;

[0008] A mold assembly is provided between the movable plate and the worktable. The mold assembly includes an upper mold and a lower mold. The upper mold is fixed to the lower surface of the movable plate. A mold groove is opened on the upper surface of the worktable. The lower mold is slidably installed in the mold groove.

[0009] The side wall of the frame is provided with several slots, and a force transmission mechanism is provided in the slots;

[0010] A vibration mechanism is provided on the upper surface of the workbench;

[0011] A mold-pulling mechanism is provided on the lower surface of the workbench;

[0012] A feeding mechanism is provided on the upper surface of the frame.

[0013] Specifically, the lower mold is a through-hole structure, including several rectangular grooves. A bottom block is provided in the mold groove. The bottom block is used in conjunction with the lower mold. A nitrogen cylinder is fixed on the lower surface of the bottom block. The end of the nitrogen cylinder away from the bottom block is fixedly connected to the worktable. A through groove is opened in the mold groove, and a pull-down plate is slidably installed in the through groove.

[0014] Specifically, the force transmission mechanism includes two sliding arms, which are fixed to the two side walls of the moving plate. Each side wall of the sliding arm is fixed with a first toothed plate. Four force transmission shafts are rotatably mounted on the side wall of the worktable. A first gear is fixed to one end of each force transmission shaft extending out of the worktable. The first gear meshes with the first toothed plate. A worm is fixed to one end of each force transmission shaft located inside the worktable. The worm meshes with a worm wheel, which is set in a groove inside the worktable.

[0015] Specifically, the vibration mechanism includes a first rotating shaft, which is rotatably mounted on a groove inside the workbench. The worm gear is coaxially fixed with the first rotating shaft and is fixedly connected to it. The top of the first rotating shaft extends through the upper surface of the workbench. A connecting block is fixed to the end of the first rotating shaft that extends through the workbench. The connecting block is cylindrical and has several vibration components fixed in an array on its sidewalls.

[0016] Specifically, the vibration assembly includes a paddle, which is rectangular in shape and is rotatably mounted on the side wall of a connecting block. A torsion spring is provided between the connecting block and the paddle, and both ends of the torsion spring are fixedly connected to the paddle and the side wall of the connecting block, respectively.

[0017] Specifically, the pulling mechanism includes a pull-down seat, which is fixedly connected to a pull-down plate. A first telescopic rod is fixed on the upper surface of the pull-down seat. The end of the first telescopic rod away from the pull-down seat is fixedly connected to the lower surface of the worktable. A first spring is sleeved on the outer wall of the first telescopic rod. The two ends of the first spring are fixedly connected to the lower surface of the worktable and the upper surface of the pull-down seat, respectively. Two second telescopic rods are fixed on the lower surface of the inner wall of the frame. The end of the second telescopic rod away from the frame is fixedly connected to the lower surface of the pull-down seat.

[0018] Specifically, a third toothed plate is fixed on both sides of the pull-down seat, and a second toothed plate is fixed on the side wall of the sliding arm near the lower mold. A second gear is meshed between the second toothed plate and the third toothed plate, and the second gear is rotatably mounted on the side wall of the frame via a gear shaft.

[0019] Specifically, the feeding mechanism includes a material box, which is fixed to the top of the frame and extends through the bottom of the frame. The material box has an inlet pipe fixed to its outlet, and a hopper assembly is fixedly connected to the end of the inlet pipe away from the material box.

[0020] Specifically, the hopper assembly includes a hopper shell, an electric push rod fixed to the side wall of the hopper shell, the end of the electric push rod away from the hopper shell fixed to the frame, a hopper push plate slidably installed between the two side walls of the hopper shell, a hopper frame fixedly connected to the inner wall of the hopper shell, the hopper frame cooperating with the lower mold, a telescopic plate fixed to the inner wall of the hopper frame, a third telescopic rod slidably installed on the lower surface of the side wall of the hopper frame near the hopper push plate, a first buckle fixed to the side wall of the third telescopic rod, a second buckle fixed to the side wall of the hopper push plate, the first buckle being located below and in contact with the second buckle, a second spring sleeved on the outer wall of the upper half of the third telescopic rod, the two ends of the second spring being fixedly connected to the third telescopic rod and the hopper frame respectively.

[0021] Specifically, a force transmission component is provided inside the hopper shell. The force transmission component includes a fifth toothed plate, which is fixed to the side wall of the third telescopic rod. A fourth toothed plate is fixed to the telescopic short side wall of the telescopic plate. A third gear and a fourth gear are rotatably mounted on the side wall of the hopper frame. A first sprocket is fixed to the outer wall of the gear shaft of the third gear, and a second sprocket is fixed to the gear shaft of the fourth gear. The first sprocket and the second sprocket are connected by a chain drive.

[0022] The beneficial effects of this invention are:

[0023] (1) The permeable brick preparation rapid molding equipment of the present invention moves the sliding arm 31 downward, thereby driving the first toothed plate 33 to slide vertically downward. The first toothed plate 33 can drive the first gear 34 meshing with the first toothed plate 33 to rotate, thereby driving the force transmission shaft 35 to rotate, thereby driving the worm 36 to rotate. The rotation of the worm 36 can drive the worm wheel 41 to rotate, and the rotation of the worm wheel 41 can drive the connecting block 43 to rotate. Then the tapping block 441 located on the connecting block 43 can tap and vibrate the lower mold 22. The molded part is formed during the pressing process of the upper mold and the lower mold. At this time, the molded part has a certain adhesion to the inner wall of the lower mold. The tapping and vibration process can make the pre-demolding operation between the molded part and the lower mold completed before the lower mold moves down to demold, thereby increasing the stability during demolding operation, improving the yield of the molded part, and avoiding the waste of raw materials caused by broken molded parts while improving product quality.

[0024] (2) The permeable brick preparation rapid prototyping equipment of the present invention is installed on the worktable by sliding the lower mold. When demolding is required, the lower mold can be moved down along the mold groove by the operation of the mold pulling mechanism, thereby exposing the pressed finished product on the worktable. In the second cycle operation by the feeding mechanism, the finished product can be pushed to other positions on the worktable for the next cycle operation. The action of pulling down the lower mold by the mold pulling mechanism can make the demolding process of the molded part more stable and avoid the problem of the molded part breaking during the demolding process due to insufficient strength.

[0025] (3) The permeable brick preparation rapid prototyping equipment of the present invention moves the lower mold upward. At this time, the upper surface of the lower mold pushes the third telescopic rod upward. During the upward movement of the third telescopic rod, the fourth toothed plate moves upward, which in turn drives the meshing third gear to rotate. The third gear drives the first sprocket to rotate, which in turn drives the second sprocket to rotate through the transmission action of the chain. The second sprocket can drive the fourth gear to rotate, and the fourth gear can drive the fourth toothed plate to slide, which in turn drives the telescopic end of the telescopic plate to slide. At this time, the material can fall down into the lower mold along the gap between the telescopic plate and the hopper frame, completing the linkage between the lower mold and the hopper assembly. Therefore, when the lower mold does not apply pressure to the hopper assembly, the raw material in the hopper assembly will not leak. Avoiding the leakage of raw material on the table can ensure the cleanliness of the table, thereby avoiding the adhesion of impurities on the surface of the product. This greatly improves the quality of the product and saves raw materials. Attached Figure Description

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] As shown in Figures 1-14, the permeable brick preparation rapid prototyping equipment of the present invention includes a frame 1, a hydraulic press fixed on the top of the frame 1, a movable plate fixed on the telescopic end of the hydraulic press, a worktable arranged directly below the movable plate, the worktable fixed on the side wall of the frame 1, four guide rods fixed inside the frame 1, and the movable plate and the worktable slidably connected to the guide rods.

[0045] A mold assembly 2 is provided between the movable plate and the worktable. The mold assembly 2 includes an upper mold 21 and a lower mold 22. The upper mold 21 is fixed to the lower surface of the movable plate. A mold groove 23 is provided on the upper surface of the worktable. The lower mold 22 is slidably installed in the mold groove 23.

[0046] The frame 1 has several slots inside its side wall, and a force transmission mechanism 3 is installed in each slot;

[0047] The upper surface of the workbench is equipped with a vibration mechanism 4;

[0048] A mold pulling mechanism 5 is provided on the lower surface of the workbench;

[0049] The upper surface of the frame 1 is provided with a feeding mechanism 6, and the lower mold 22 is fixed on the frame 1. When demolding, the molded part is pushed out of the lower mold 22 and into the surface of the frame 1 by a pushing mechanism provided in the device. Since the molded part has not yet been significantly strengthened, there is a risk of damage to the molded part during this process.

[0050] In this invention, the lower mold 22 is slidably mounted on the worktable, and the mold assembly before pressing is placed on the worktable. The vibration mechanism 4 can vibrate the material put into the lower mold 22, thereby making the material distribution in the lower mold 22 uniform. The uniformly mixed material during pressing ensures that the finished product does not have uneven density. The lower mold 22 is slidably mounted on the worktable. When demolding is required, the mold pulling mechanism 5 can move the lower mold 22 downward along the mold groove 23, thereby exposing the pressed finished product on the worktable. In the second cycle operation, the feeding mechanism 6 can push the finished product to other positions on the worktable for the next cycle operation.

[0051] By separating the lower mold 22 fixing base from the worktable, and with the working effect of the vibration mechanism 4, the problem of uneven density of the finished product can be largely solved. Furthermore, by pulling down the lower mold 22 through the mold pulling mechanism 5, the demolding process of the molded part can be made more stable, avoiding the problem of the molded part breaking during demolding due to insufficient strength.

[0052] Specifically, the lower mold 22 is a through-hole structure, including several rectangular grooves. A bottom block 26 is provided in the mold groove 23. The bottom block 26 is used in conjunction with the lower mold 22. A nitrogen cylinder 25 is fixed on the lower surface of the bottom block 26. The end of the nitrogen cylinder 25 away from the bottom block 26 is fixedly connected to the worktable. A through groove is opened in the mold groove 23. A pull-down plate 553 is slidably installed in the through groove.

[0053] In this invention, by setting the bottom block 26 to work in conjunction with the lower mold 22, the material put into the lower mold 22 can be supported and shaped. When the hydraulic press drives the moving plate and the upper mold 21 to move downward to perform the pressing operation, after the pressed material reaches a certain pressure, the bottom block 26 will move slightly downward under the pressure limit of the nitrogen cylinder 25, thereby avoiding the high density of the molded part due to excessive pressure.

[0054] The permeability of permeable bricks is ensured by controlling the size of the pores and the density of the slag during the molding process. This invention uses a nitrogen cylinder 25 for pressure limiting to prevent the density of the molded parts from being too high, thus ensuring the size of the pores inside the molded parts. This prevents the permeability of the product from weakening due to excessive compaction, ensuring the quality of the finished product. As a result, the product has good permeability during use, allowing road surface water and rainwater to quickly seep into the product and increase the comfort of users.

[0055] Specifically, the force transmission mechanism 3 includes two sliding arms 31, which are fixed to the two side walls of the moving plate. Each side wall of the sliding arm 31 is fixed with a first toothed plate 33. Four force transmission shafts 35 are rotatably mounted on the side wall of the worktable. A first gear 34 is fixed to one end of the force transmission shaft 35 extending out of the worktable. The first gear 34 meshes with the first toothed plate 33. A worm 36 is fixed to one end of the force transmission shaft 35 located inside the worktable. The worm 36 meshes with a worm wheel 41, which is set in a groove inside the worktable.

[0056] Specifically, the vibration mechanism 4 includes a first rotating shaft 42, which is rotatably mounted on a groove inside the workbench. The worm gear 41 is coaxially fixed with the first rotating shaft 42 and is fixedly connected to the first rotating shaft 42. The top of the first rotating shaft 42 extends through the upper surface of the workbench. A connecting block 43 is fixed to the end of the first rotating shaft 42 that extends through the workbench. The connecting block 43 is cylindrical and has several vibration components fixed in an array on its sidewalls.

[0057] Specifically, the vibration assembly 44 includes a paddle 441, which is rectangular in shape. The paddle 441 is rotatably mounted on the side wall of the connecting block 43. A torsion spring 442 is provided between the connecting block 43 and the paddle 441. The two ends of the torsion spring 442 are fixedly connected to the paddle 441 and the side wall of the connecting block 43, respectively.

[0058] In this invention, as the hydraulic press drives the moving plate downward, it simultaneously drives the sliding arm 31 downward. The sliding arm 31 then drives the first toothed plate 33 to slide vertically downward. The first toothed plate 33 can drive the first gear 34, which meshes with it, to rotate, thereby driving the force transmission shaft 35 to rotate, which in turn drives the worm gear 36 to rotate. The rotation of the worm gear 36 drives the worm wheel 41 to rotate, which in turn drives the connecting block 43 to rotate. Consequently, the striking block 441 located on the connecting block 43 can perform tapping vibration on the lower mold 22. Because the striking block 441 is rotatably connected to the connecting block 43, the tapping vibration action of the striking block 441 on the lower mold 22 is guaranteed to be orderly, reliable, and relatively gentle. Furthermore, a torsion spring 442 is provided at the rotatable connection point, ensuring that the rotating striking block 441 can be promptly reset during the tapping vibration operation.

[0059] The gentler tapping vibration method can ensure that the outer wall of the lower mold 22 is not damaged, thereby extending the service life of the lower mold 22 and saving raw material costs. In addition, the tapping vibration can separate the molded parts inside the lower mold 22 from the inner wall of the lower mold 22, so that the molded parts inside can be better demolded when the lower mold 22 moves down to discharge material, thereby ensuring product quality.

[0060] Specifically, the pulling mechanism 5 includes a pull-down seat 55, which is fixedly connected to a pull-down plate 553. A first telescopic rod 551 is fixedly mounted on the upper surface of the pull-down seat 55. One end of the first telescopic rod 551 away from the pull-down seat 55 is fixedly connected to the lower surface of the workbench. A first spring 552 is sleeved on the outer wall of the first telescopic rod 551. Both ends of the first spring 552 are fixedly connected to the lower surface of the workbench and the upper surface of the pull-down seat 55, respectively. Two second telescopic rods 56 are fixedly mounted on the lower surface of the inner wall of the frame 1. One end of the second telescopic rod 56 away from the frame 1 is fixedly connected to the lower surface of the pull-down seat 55.

[0061] Specifically, a third toothed plate 53 is fixed on both side walls of the pull-down seat 55, and a second toothed plate 52 is fixed on the side wall of the sliding arm 31 near the lower mold 22. A second gear 54 is meshed between the second toothed plate 52 and the third toothed plate 53. The second gear 54 is rotatably mounted on the side wall of the frame 1 through a gear shaft.

[0062] In this invention, by setting the second toothed plate 52 and the third toothed plate 53 to mesh with the second gear 54 simultaneously, after the pressing and molding operation is completed, the hydraulic press drives the moving plate to move upward, which in turn drives the connecting plate 51 to move upward. When the second toothed plate 52 begins to contact the third gear 651, it can drive the third gear 651 to rotate, which in turn drives the meshing third toothed plate 53 to move. Then the third toothed plate 53 drives the pull-down seat 55 to move downward, which in turn drives the pull-down plate 553 to move downward, which in turn drives the lower mold 22 to move downward. Since the molded part located in the lower mold 22 is supported by the bottom block 26, it will not move downward with the lower mold 22. When the lower mold 22 is fully embedded in the mold groove 23, the hydraulic press stops under the control of the central control system, and the upper surface of the lower mold 22 is flush with the upper surface of the worktable, thus completing the demolding operation.

[0063] Specifically, the feeding mechanism 6 includes a material box 61, which is fixed to the top of the frame 1 and extends through the bottom of the frame 1. The material box 61 has an inlet pipe 62 fixed at its outlet, and a hopper assembly 63 is fixedly connected to the end of the inlet pipe 62 away from the material box 61.

[0064] Specifically, the hopper assembly 63 includes a hopper shell 631, with an electric push rod 64 fixed to the side wall of the hopper shell 631. One end of the electric push rod 64 away from the hopper shell 631 is fixed to the frame 1. A hopper push plate 636 is slidably installed between the two side walls of the hopper shell 631. A hopper frame 632 is fixedly connected to the inner wall of the hopper shell 631. The hopper frame 632 works in conjunction with the lower mold 22. A telescopic plate 633 is fixed to the inner wall of the hopper frame 632. The hopper frame 632 is close to the hopper push plate. A third telescopic rod 634 is slidably installed on the lower surface of the side wall of plate 636. A first buckle 6341 is fixed on the side wall of the third telescopic rod 634, and a second buckle 6361 is fixed on the side wall of the hopper push plate 636. The first buckle 6341 is located below and in contact with the second buckle 6361. A second spring 635 is sleeved on the outer wall of the upper half of the third telescopic rod 634. The two ends of the second spring 635 are fixedly connected to the third telescopic rod 634 and the hopper frame 632, respectively.

[0065] Specifically, a force transmission component 65 is provided inside the hopper shell 631. The force transmission component 65 includes a fifth toothed plate 656, which is fixed to the side wall of the third telescopic rod 634. A fourth toothed plate 655 is fixed to the telescopic short side wall of the telescopic plate 633. A third gear 651 and a fourth gear 654 are rotatably mounted on the side wall of the hopper frame 632. A first sprocket 652 is fixed to the outer wall of the gear shaft of the third gear 651. A second sprocket 657 is fixed to the gear shaft of the fourth gear 654. The first sprocket 652 and the second sprocket 657 are connected by a chain 653.

[0066] In this invention, raw materials pass through the hopper 61 and enter the feed pipe 62, eventually entering the hopper shell 631. Due to the obstruction of the telescopic plate 633 and the hopper push plate 636, the raw materials do not leak out. Then, through the pushing action of the electric push rod 64, the hopper assembly 63 is driven to move horizontally along the worktable to directly above the lower mold 22 embedded in the mold groove 23. During this process, the hopper push plate 636 pushes the formed and demolded part away from the bottom block 26. Then, under the control of the central control system, the hydraulic press continues to move upward. As the second toothed plate 52 moves upward and disengages from the second gear 54, the third toothed plate 53 is released from its restraint. Under the action of the elastic potential energy of the first spring 552, the pull-down seat 55 moves upward. This pushes the lower mold 22 upward. At this time, the upper surface of the lower mold 22 pushes the third telescopic rod 634 upward. During the upward movement of the third telescopic rod 634, it drives the fourth toothed plate 655 upward, which in turn drives the meshing third gear 651 to rotate. The third gear 651 then drives the first sprocket 652 to rotate, which in turn drives the second sprocket 657 to rotate through the transmission action of the chain 653. The second sprocket 657 can then drive the fourth gear 654 to rotate, and the fourth gear 654 can drive the fourth toothed plate 655 to slide, which in turn drives the telescopic end of the telescopic plate 633 to slide. At this time, the material can fall down into the lower mold 22 along the gap between the telescopic plate 633 and the hopper frame 632, completing the feeding process.

[0067] As the third telescopic rod 634 moves upward, it also drives the first latch 6341 to move upward, which in turn drives the second latch 6361 to move, which in turn drives the hopper push plate 636 to slide upward. At this time, the hydraulic press is still in operation, and the moving plate is still moving upward, which in turn drives the sliding arm 31 to move, and at the same time drives the first connecting rod 32 to move upward, which in turn drives the second connecting rod 33 to move, which in turn pulls the third connecting rod 34 to slide towards the side wall of the frame 1. Then, during the return reset process, the first toothed plate 35 drives the meshing turbine 41 to rotate again, which in turn drives the connecting block 43 to rotate, which in turn drives the patting block 441 to pat and vibrate the hopper shell 631, further ensuring the uniformity of the raw material inside the lower mold 22.

[0068] After the feeding operation is completed, the electric push rod 64 is retracted under the control of the central control system, which in turn drives the hopper assembly 63 to return to its original position. In this invention, the lower mold 22 has a straight slope on its side wall. During the return process, as the third telescopic rod 634 moves along the slope, the elastic potential energy of the second spring 635 can drive the third telescopic rod 634 to press against the slope. The downward-moving third telescopic rod 634 can drive the force transmission assembly 65 to work, which can eventually cause the telescopic plate 633 to extend outward. Before the hopper assembly 63 disengages from the lower mold 22, the telescopic plate 633 completes the closing and resetting, preventing the internal material from leaking out. During this process, the hopper push plate 636 clamps the upper surface of the lower mold 22, which can scrape the upper surface of the material inside the lower mold 22. After disengaging from the lower mold 22, the hopper push plate 636 moves downward due to its own gravity, thus completing the resetting.

[0069] The linkage between the lower mold 22 and the third connecting rod 34 ensures that the hopper assembly 63 can be opened accurately when feeding is required, thus facilitating feeding. After feeding is completed, the sloping design on the side of the lower mold 22, in conjunction with the second spring 635, can close the hopper assembly 63 in a timely manner, thus ensuring that there is no waste of materials, saving a lot of material resources, and keeping the worktable clean. At the same time, it also ensures that the bottom surface of the hopper assembly 63 will not rub against the materials on the worktable during horizontal movement, thereby extending the service life of the hopper assembly 63 and saving a lot of material and equipment costs.

[0070] Working principle: During operation, as the hydraulic press moves the moving plate downwards, it simultaneously moves the upper mold 21 downwards, working in conjunction with the lower mold 22 to complete the pressing and forming operation. Simultaneously, it moves the sliding arm 31 downwards, which in turn causes the first toothed plate 33 to slide vertically downwards. The first toothed plate 33 drives the first gear 34, which meshes with it, to rotate, thereby driving the power transmission shaft 35 to rotate, which in turn drives the worm gear 36 to rotate. The rotation of the worm gear 36 drives the worm wheel 41 to rotate, which in turn drives the connecting block 43 to rotate. The tapping block 441 located on the connecting block 43 then vibrates the lower mold 22. Because the tapping block 441 is rotatably connected to the connecting block 43, the tapping vibration of the tapping block 441 on the lower mold 22 is relatively gentle. Furthermore, a torsion spring 442 is provided at the rotatable connection to ensure that the rotating tapping block 441 can be promptly reset during the tapping vibration operation.

[0071] When the hydraulic press moves upward, the second toothed plate 52 and the third toothed plate 53 simultaneously mesh with the second gear 54. After the pressing and molding operation is completed, the hydraulic press drives the moving plate to move upward, which in turn drives the connecting plate 51 to move upward. When the second toothed plate 52 begins to contact the third gear 651, it can drive the third gear 651 to rotate, which in turn drives the meshing third toothed plate 53 to move. Then the third toothed plate 53 drives the pull-down seat 55 to move downward, which in turn drives the pull-down plate 553 to move downward, which in turn drives the lower mold 22 to move downward. Since the molded part located in the lower mold 22 is supported by the bottom block 26, it will not move downward with the lower mold 22. When the lower mold 22 is fully embedded in the mold groove 23, the hydraulic press stops under the control of the central control system. The upper surface of the lower mold 22 is flush with the upper surface of the worktable, thus completing the demolding operation.

[0072] Subsequently, the raw material passes through the hopper 61 and enters the feed pipe 62, eventually entering the hopper shell 631. Due to the obstruction of the telescopic plate 633 and the hopper push plate 636, the raw material will not leak out of the hopper shell 631. Then, through the pushing action of the electric push rod 64, the hopper assembly 63 is driven to move horizontally along the worktable to directly above the lower mold 22 embedded in the mold groove 23. During this process, the hopper push plate 636 pushes the formed and demolded part away from the bottom block 26. Then, under the control of the central control system, the hydraulic press continues to move upward. As the second toothed plate 52 moves upward and disengages from the second gear 54, the third toothed plate 53 is released from its restraint. Under the action of the elastic potential energy of the first spring 552, it drives the pull-down seat 55 to move upward. This pushes the lower mold 22 upward, and the upper surface of the lower mold 22 pushes the third telescopic rod 634 upward. During the upward movement of the third telescopic rod 634, the fourth toothed plate 655 moves upward, which in turn drives the meshing third gear 651 to rotate. The third gear 651 then drives the first sprocket 652 to rotate, which in turn drives the second sprocket 657 to rotate through the transmission action of the chain 653. The second sprocket 657 can then drive the fourth gear 654 to rotate, and the fourth gear 654 can drive the fourth toothed plate 655 to slide, which in turn drives the telescopic end of the telescopic plate 633 to slide. At this time, the material can fall down into the lower mold 22 along the gap between the telescopic plate 633 and the hopper frame 632, completing the feeding process.

[0073] As the third telescopic rod 634 moves upward, it will also drive the first buckle 6341 to move upward, which in turn drives the second buckle 6361 to move, which in turn drives the hopper push plate 636 to slide upward. At this time, the hydraulic press is still in operation, and the moving plate is still moving upward, which in turn drives the sliding arm (31) to move, and at the same time drives the first connecting rod 32 to move upward, which in turn drives the second connecting rod 33 to move, which in turn pulls the third connecting rod 34 to slide towards the side wall of the frame 1. Then, during the return reset process, the first toothed plate 35 drives the meshing worm gear 41 to rotate again, which in turn drives the connecting block 43 to rotate, which in turn drives the patting block 441 to pat and vibrate the hopper shell 631.

[0074] After the feeding operation is completed, the electric push rod 64 is retracted under the control of the central control system, which in turn drives the hopper assembly 63 to return to its original position. In this invention, the lower mold 22 has a straight slope on its side wall. During the return process, as the third telescopic rod 634 moves along the slope, the elastic potential energy of the second spring 635 can drive the third telescopic rod 634 to press against the slope. The downward-moving third telescopic rod 634 can drive the force transmission assembly 65 to work, which can eventually cause the telescopic plate 633 to extend outward. Before the hopper assembly 63 disengages from the lower mold 22, the telescopic plate 633 completes the closing and resetting, preventing the internal material from leaking out. During this process, the hopper push plate 636 clamps the upper surface of the lower mold 22, which can scrape the upper surface of the material inside the lower mold 22. After disengaging from the lower mold 22, the hopper push plate 636 moves downward due to its own gravity, thus completing the resetting.
