Description

Technical Field

[0001] This invention relates to the field of graphite product pressing technology, and more specifically, to a graphite product pressing and molding equipment with a demolding mechanism and a method of using it. Background Technology

[0002] One of the main uses of graphite is in the production of refractory materials, including refractory bricks, crucibles, continuous casting powders, mold cores, molds, detergents, and high-temperature resistant materials. In recent years, two significant changes in the refractory industry have been the widespread use of magnesia-carbon bricks in steelmaking furnace linings and the application of alumina-carbon bricks in continuous casting. This has closely linked graphite refractories with the steelmaking industry, which consumes approximately [amount missing] of the world's refractory materials.

[0003] Graphite products are pressed into different shapes depending on their intended use during the pressing process. Rectangles are a common shape used in pressing, requiring rectangular molds. The pressed workpieces are also rectangular. When pressing, from the perspective of side length alone, the shorter side is generally more fragile than the longer side. This is because when subjected to the same external force, the shorter side has a smaller range of force dispersion. Under strong pressing, the shorter side of the rectangular mold is more fragile and cannot provide good support, easily leading to defective products. In addition, most existing graphite product pressing equipment relies on manual demolding, which is time-consuming and labor-intensive and can easily damage the pressed finished products. Summary of the Invention

[0004] The purpose of this invention is to provide a graphite product pressing and molding equipment and its method of use with a demolding mechanism. This graphite product pressing and molding equipment with a demolding mechanism can effectively support and protect the short side of the pressing groove during the pressing process, reducing the occurrence of defective products and improving product quality. Simultaneously, direct demolding through a reinforced structure reduces damage to the product, and the combined effect of two injections of release fluid allows for easy demolding. This addresses the problem that the short side of a rectangular mold is relatively short, resulting in a smaller range of force distribution. Under strong pressing, the short side of a rectangular mold is more vulnerable and cannot provide adequate support, easily leading to defective products.

[0005] To achieve the above objectives, a graphite product pressing and molding equipment with a demolding mechanism is provided, including a base, a top platform above the base, four sets of hydraulic cylinders fixedly connected between the bottom of the top platform and the top of the base, a movable table fixedly connected to the surface of the hydraulic cylinders, a connecting rod fixedly connected to the bottom of the movable table, a pressing plate fixedly connected to the bottom end of the connecting rod, a pressing groove fixedly connected to the top of the base and directly below the pressing plate, and second reinforcing plates fixedly connected to both sides of the pressing groove, the sides of the second reinforcing plates being inclined surfaces;

[0006] Also includes:

[0009] As a further improvement to this technical solution, the inner cavity of the base is provided with a U-shaped groove. One end of the U-shaped groove is slidably connected to a first sliding plate, and the other end of the U-shaped groove is slidably connected to a second sliding plate.

A connecting block is fixedly connected to the top of the second sliding plate, and the top of the connecting block is fixedly connected to the bottom of the first reinforcing plate.

[0010] As a further improvement to this technical solution, a sliding groove is provided on the top of the base, a slider is fixedly connected to the bottom of the three reinforcing plates, the surface of the slider is slidably connected to the inner cavity of the sliding groove, an extrusion plate is fixedly connected to the surface of the extrusion rod, one side of the extrusion plate is an inclined surface, the angle of the inclined surface of the extrusion plate is the same as that of the inclined surface of the third reinforcing plate, and a first spring is fixedly connected between one side of the base and the vertical surface of the third reinforcing plate.

[0011] As a further improvement to this technical solution, the inner cavity of the base is provided with an installation groove, the inner cavity of the installation groove is rotatably connected to a gear, the top of the gear meshes with a toothed plate, the top of the toothed plate is fixedly connected to a moving rod, the top of the moving rod passes through the base, and the base is provided with a slot for the moving rod to move.

[0012] As a further improvement to this technical solution, a docking cylinder is fixedly connected to one side of the moving rod, a second limiting block is fixedly connected to the inner cavity of the docking cylinder, and plug-in pins are fixedly connected to both sides of the third reinforcing plate, with a first limiting pin that matches the second limiting block fixedly connected to the end of the plug-in pin.

[0013] As a further improvement to this technical solution, a pad is provided at the bottom of the pressing groove, a worm gear is meshed with one side of the gear, and ejector rods are fixedly connected to both the upper and lower ends of the worm gear, with the ejector rods contacting the bottom of the pad.

[0014] As a further improvement to this technical solution, a spray cylinder is fixedly connected to the base, and a spray pipe is connected to the top of the spray cylinder, with a control valve installed on the spray pipe.

[0015] As a further improvement to this technical solution, a rotating rod is rotatably connected to the control valve, and the rotating rod is located below the pressing plate.

[0016] As a further improvement to this technical solution, a horizontal plate is fixedly connected to both the upper and lower ends of the control valve, and a second spring is fixedly connected between the horizontal plate and the rotating rod.

[0017] The second objective of this invention is to provide a method for using a graphite product compression molding equipment with a demolding mechanism, comprising the following steps:

[0018] S1. Material preparation: Place the graphite raw material evenly into the pressing tank, ensuring that the raw material is filled to the preset height;

[0019] S2. Pressing and Reinforcing: The hydraulic cylinder is activated, driving the moving platform, connecting rod, and pressing plate to move downwards; simultaneously, the connecting rod drives the extrusion rod to descend, and the extrusion rod pushes the first reinforcing plate upwards through the sliding ball until it is completely in contact with the inclined surface of the second reinforcing plate; at the same time, the extrusion plate on the extrusion rod pushes the third reinforcing plate to move horizontally, compressing the first reinforcing plate to form a stable support; during the descent of the pressing plate, the rotating rod is triggered, triggering the nozzle to spray the release liquid into the pressing tank for the first time, and then the pressing plate completes the pressing of the raw material;

[0020] S3. Demolding: After pressing is completed, the hydraulic cylinder drives the pressing plate to rise, the extrusion rod moves up synchronously, the first spring pulls the third reinforcing plate to reset, which drives the toothed plate to move through the plug-in column, and through the gear and worm gear transmission, the ejector rod lifts the pad plate and ejects the molded product; during the rising process of the pressing plate, it touches the rotating rod again, triggering the nozzle to spray the demolding liquid for the second time, which helps the product to smoothly leave the pressing groove.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In the graphite product pressing and molding equipment and its usage method with a demolding mechanism, during pressing, the moving table drives the connecting rod and the pressing plate to press down. At this time, the connecting rod drives the extrusion rod to descend. While the extrusion rod descends, it extrudes the sliding ball in the U-shaped groove. The sliding ball moves towards the other end of the U-shaped groove, pushing the first reinforcing plate upward. At the same time, the extrusion rod descends, driving the extrusion plate to press the third reinforcing plate, causing the third reinforcing plate to move towards the first reinforcing plate. When the first reinforcing plate is pushed to the same height as the second reinforcing plate, the third reinforcing plate is squeezed to the position of contact with the first reinforcing plate. At this time, the three sets of reinforcing plates are tightly attached, and the extrusion plate and the sliding ball provide lateral and vertical support forces respectively, making the three sets of reinforcing plates more solid. This supports and protects the short side of the pressing groove, allowing the pressing to proceed smoothly, reducing the occurrence of defective products, and improving production quality.

[0023] 2. In the graphite product pressing and molding equipment and its usage method with a demolding mechanism, during the pressing process, when the third reinforcing plate is in close contact with the first reinforcing plate, the insertion post is inserted into the inner cavity of the docking cylinder and is limited by the first and second limiting blocks. After pressing is completed, the pressing plate rises and the third reinforcing plate resets under the elastic force of the first spring. During the reset process, the docking cylinder moves, the docking cylinder moves, the toothed plate moves, the toothed plate moves, the gear rotates, the gear rotates, the worm moves upward, the worm moves, the ejector rod moves upward, and the pad is ejected, thereby ejecting the entire pressed product from the mold. Demolding is achieved directly through the reinforcing structure, eliminating the need for manual demolding. This simplifies operation, saves manpower, and reduces damage to the product.

[0024] 3. In the graphite product pressing and molding equipment and its usage method with a demolding mechanism, when the pressing plate descends and contacts the end of the rotating rod during the pressing process, the rotating rod rotates. At this time, the control valve opens the spray pipe to spray demolding liquid into the pressing tank in advance. The pressing plate continues to descend and disengages from the rotating rod. Under the elastic force of the second spring, the rotating rod resets. When the pressing is completed, the pressing plate rises and contacts the end of the rotating rod, causing the rotating rod to rotate. At this time, the control valve opens the spray pipe to spray demolding liquid into the pressing tank a second time. The two sprayings of demolding liquid, combined with the demolding device, make the product easily demolded. Attached Figure Description

[0041] Also includes:

[0042] The first reinforcing plate 15 penetrates the base 1 and is located on the side of the second reinforcing plate 16. The surfaces of the first reinforcing plate 15 and the second reinforcing plate 16 adjacent to each other are inclined surfaces. The first reinforcing plate 15 can move in the vertical direction, and when the first reinforcing plate 15 rises to the same height as the second reinforcing plate 16, the inclined surface of the second reinforcing plate 16 is completely in contact with the inclined surface of the first reinforcing plate 15.

[0043] The first reinforcing plate 15 provides the first layer of support for the short side of the pressing groove 7, so that the short side of the pressing groove 7 is supported during the pressing process and will not deform.

[0044] The third reinforcing plate 17 is triangular in shape, and its vertical surface is adjacent to the vertical surface of the first reinforcing plate 15. The third reinforcing plate 17 can move in the horizontal direction to compress and reinforce the first reinforcing plate 15.

[0045] The inner cavity of the base 1 is provided with a U-shaped groove 10. One end of the U-shaped groove 10 is slidably connected to a first sliding plate 11, and the other end of the U-shaped groove 10 is slidably connected to a second sliding plate 13. The inner cavity of the U-shaped groove 10, located between the first sliding plate 11 and the second sliding plate 13, is filled with sliding beads 12. A pressing rod 8 is fixedly connected to the surface of the connecting rod 5. The pressing rod 8 passes through the top of the base 1 and extends above the first sliding plate 11. A connecting block 14 is fixedly connected to the top of the second sliding plate 13. The top of the connecting block 14 is fixedly connected to the bottom of the first reinforcing plate 15.

[0046] When the U-shaped groove 10 is positioned, the first reinforcing plate 15 can rise smoothly to the same height as the second reinforcing plate 16, and the sliding ball 12 slides inside the U-shaped groove 10 and will move when subjected to compressive force.

[0047] The top of the base 1 is provided with a sliding groove 19. The bottom of the third reinforcing plate 17 is fixedly connected with a slider 18. The surface of the slider 18 is slidably connected to the inner cavity of the sliding groove 19. The surface of the extrusion rod 8 is fixedly connected with an extrusion plate 9. One side of the extrusion plate 9 is an inclined surface. The angle between the inclined surface of the extrusion plate 9 and the inclined surface of the third reinforcing plate 17 is the same. A first spring 38 is fixedly connected between one side of the base 1 and the vertical surface of the third reinforcing plate 17.

[0048] During pressing, the moving table 4 drives the connecting rod 5 and the pressing plate 6 to press down. At this time, the connecting rod 5 drives the extrusion rod 8 to descend. As the extrusion rod 8 descends, it extrudes the sliding ball 12 in the U-shaped groove 10. The sliding ball 12 moves towards the other end of the U-shaped groove 10, pushing the first reinforcing plate 15 upward. At the same time, the extrusion rod 8 descends, driving the extrusion plate 9 to extrude the third reinforcing plate 17, causing the third reinforcing plate 17 to move towards the first reinforcing plate 15. When the first reinforcing plate 15 is pushed to the same height as the second reinforcing plate 16, the third reinforcing plate 17 is extruded to the position of contact with the first reinforcing plate 15. At this time, the three sets of reinforcing plates are tightly attached, and the extrusion plate 9 and the sliding ball 12 provide lateral and vertical support forces respectively, making the three sets of reinforcing plates more solid and supporting and protecting the short side of the pressing groove 7, so that the pressing can proceed smoothly, reducing the occurrence of defective products and improving production quality.

[0049] The rising of the first reinforcing plate 15 and the lateral movement of the third reinforcing plate 17 are synchronized. When the pressing plate 6 is pressed down to the lowest position, the three sets of reinforcing plates are completely close together and at the same height.

[0050] The inner cavity of the base 1 is provided with a mounting groove 27. A gear 29 is rotatably connected to the inner cavity of the mounting groove 27. A toothed plate 28 meshes with the top of the gear 29. A moving rod 23 is fixedly connected to the top of the toothed plate 28. The top of the moving rod 23 passes through the base 1. A slot 26 is provided on the base 1 for the moving rod 23 to move.

[0051] A docking cylinder 24 is fixedly connected to one side of the moving rod 23. A second limiting block 25 is fixedly connected to the inner cavity of the docking cylinder 24. Insertion pins 21 are fixedly connected to both sides of the third reinforcing plate 17. A first limiting block 22 that matches the second limiting block 25 is fixedly connected to the end of the insertion pin 21. A pad 20 is provided at the bottom of the pressing groove 7. A worm gear 31 is meshed with one side of the gear 29. Ejector rods 30 are fixedly connected to both the upper and lower ends of the worm gear 31. The ejector rods 30 are in contact with the bottom of the pad 20.

[0052] The second limiting block 25 and the first limiting block 22 are made of rubber. When the first spring 38 resets the second limiting block 25 and the first limiting block 22 are separated under the action of external force, so that the docking cylinder 24 and the plug-in post 21 are separated.

[0053] The mounting slot 27 is located in the middle of the base 1 and below the pressing slot 7, while the U-shaped slot 10 is located near the two sides of the base 1. The two slots do not contact each other.

[0054] During the pressing process, when the third reinforcing plate 17 is in close contact with the first reinforcing plate 15, the insertion post 21 is inserted into the inner cavity of the docking cylinder 24 and is limited by the first limiting block 22 and the second limiting block 25. After pressing is completed, the pressing plate 6 rises and the third reinforcing plate 17 is reset under the elastic force of the first spring 38. During the reset process, the docking cylinder 24 is moved, the docking cylinder 24 moves, the toothed plate 28 moves, the toothed plate 28 moves, the gear 29 rotates, the gear 29 rotates, the worm 31 moves upward, the worm 31 moves, the ejector rod 30 moves upward, and the pad 20 is ejected, thereby ejecting the entire pressed product from the mold. Direct demolding is achieved through the reinforcing structure, eliminating the need for manual demolding. This simplifies the operation, saves manpower, and reduces damage to the product.

[0055] The first spring 38 is a powerful spring with sufficient elasticity to move the toothed plate 28.

[0056] A spray cylinder 32 is fixedly connected to the base 1. A spray pipe 33 is connected to the top of the spray cylinder 32. A control valve 34 is provided on the spray pipe 33. A rotating rod 35 is rotatably connected to the control valve 34. The rotating rod 35 is located below the pressing plate 6.

[0057] A horizontal plate 36 is fixedly connected to both the upper and lower ends of the control valve 34, and a second spring 37 is fixedly connected between the horizontal plate 36 and the rotating rod 35.

[0058] The control valve 34 is a disc valve. The valve is opened and closed by adjusting the valve plate through the rotating rod 35. Therefore, rotating the rotating rod 35 can open or close the control valve 34.

[0059] When the pressing plate 6 descends and contacts the end of the rotating rod 35 during the pressing process, the rotating rod 35 rotates. At this time, the control valve 34 opens the spray pipe 33 to spray the release liquid into the pressing groove 7 in advance. The pressing plate 6 continues to descend and disengages from the rotating rod 35. Under the elastic force of the second spring 37, the rotating rod 35 returns to its original position. When the pressing is completed, the pressing plate 6 rises and contacts the end of the rotating rod 35, causing the rotating rod 35 to rotate. At this time, the control valve 34 opens the spray pipe 33 to spray the release liquid into the pressing groove 7 a second time. The two injections of release liquid, combined with the demolding device, make the product easy to demold.

[0060] The second objective of this invention is to provide a method for using a graphite product compression molding equipment with a demolding mechanism, comprising the following steps:

[0061] S1. Material preparation: Place the graphite raw material evenly into the pressing tank 7, ensuring that the raw material is filled to the preset height;

[0062] S2. Pressing and Reinforcing: Start the hydraulic cylinder 2 to drive the moving platform 4, connecting rod 5 and pressing plate 6 to move downward; simultaneously, the connecting rod 5 drives the extrusion rod 8 to descend, and the extrusion rod 8 pushes the first reinforcing plate 15 to rise through the sliding ball 12 until it is completely in contact with the inclined surface of the second reinforcing plate 16; at the same time, the extrusion plate 9 on the extrusion rod 8 pushes the third reinforcing plate 17 to move horizontally, extruding the first reinforcing plate 15 to form a stable support; during the descent of the pressing plate 6, it triggers the rotating rod 35, triggering the nozzle 33 to spray the release liquid into the pressing tank 7 for the first time, and then the pressing plate 6 completes the pressing of the raw material;

[0063] S3. Demolding: After pressing, the hydraulic cylinder 2 drives the pressing plate 6 to rise, the extrusion rod 8 moves upward synchronously, the first spring 38 pulls the third reinforcing plate 17 to reset, which drives the toothed plate 28 to move through the plug-in column 21, and through the gear 29 and worm gear 31, the ejector rod 30 lifts the pad plate 20 and ejects the molded product; during the rising process of the pressing plate 6, it touches the rotating rod 35 again, triggering the nozzle 33 to spray the demolding liquid for the second time, which helps the product to smoothly leave the pressing groove 7.

[0064] Working principle:

[0065] Pressing process: During pressing, the moving table 4 drives the connecting rod 5 and the pressing plate 6 to press down. At this time, the connecting rod 5 drives the extrusion rod 8 to descend. While the extrusion rod 8 descends, it extrudes the sliding ball 12 in the U-shaped groove 10. The sliding ball 12 moves towards the other end of the U-shaped groove 10 and pushes the first reinforcing plate 15 upward. At the same time, the extrusion rod 8 descends and drives the extrusion plate 9 to extrude the third reinforcing plate 17, so that the third reinforcing plate 17 moves towards the first reinforcing plate 15. When the first reinforcing plate 15 is pushed to the same height as the second reinforcing plate 16, the third reinforcing plate 17 is extruded to the position of contact with the first reinforcing plate 15. At this time, the three sets of reinforcing plates are tightly attached, and the extrusion plate 9 and the sliding ball 12 provide lateral and vertical support forces respectively, making the three sets of reinforcing plates more solid and supporting and protecting the short side of the pressing groove 7. At the same time, when the pressing plate 6 descends and contacts the end of the rotating rod 35 during the pressing process, the rotating rod 35 rotates. At this time, the control valve 34 opens the spray pipe 33 to spray the release liquid into the pressing groove 7 in advance.

[0066] Demolding process: During the pressing process, when the third reinforcing plate 17 is in close contact with the first reinforcing plate 15, the insertion post 21 is inserted into the inner cavity of the docking cylinder 24 and is limited by the first limiting block 22 and the second limiting block 25. After pressing is completed, the pressing plate 6 rises and the third reinforcing plate 17 is reset under the elastic force of the first spring 38. During the reset process, the docking cylinder 24 is moved, the docking cylinder 24 moves, the toothed plate 28 moves, the toothed plate 28 moves, the gear 29 rotates, the gear 29 rotates, the worm 31 moves upward, the worm 31 moves, the ejector rod 30 moves upward, and the pad 20 is ejected, thereby ejecting the entire pressed product from the mold. At the same time, when the pressing plate 6 rises after pressing is completed, it contacts the end of the rotating rod 35, causing the rotating rod 35 to rotate. At this time, the control valve 34 opens the spray pipe 33 to spray the demolding liquid into the pressing groove 7 a second time. The injection of the demolding liquid twice, together with the demolding device, makes the product easy to demold.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
