Technical Field
[0001] This utility model relates to the field of refractory material pressing technology, specifically a refractory material pressing and molding device. Background Technology
[0002] Refractory materials are generally inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the temperature in Celsius at which a conical specimen of refractory material can resist high temperature without softening or melting under no load. After the refractory material is produced, high-pressure stamping is generally used to ensure the molding.
[0003] A search revealed that the announcement number is CN221677550U, and the name is "A semi-dry pressing and molding device for refractory material production, including a platform." Research and analysis revealed that although it has the advantage of controlling the pressure during refractory material pressing and molding, it also has the following disadvantages to a certain extent.
[0004] For example, the inability to intermittently and equally feed refractory materials results in a large difference in the amount of refractory material discharged into the mold each time, which increases the error of the same batch of pressing and molding. Furthermore, it is inconvenient to fill the mold with refractory materials better, and a pusher plate is required to push them. In order to solve the above technical problems, we have designed a refractory material pressing and molding device. Utility Model Content
[0005] The purpose of this invention is to provide a refractory material pressing and molding device, which has the advantages of intermittent equal feeding and better filling of refractory material into the mold. It solves the problem that the amount of refractory material discharged into the mold varies greatly each time because the refractory material cannot be intermittently fed in equal amounts, and it is inconvenient to fill the mold better, requiring a pusher plate to push it.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a refractory material pressing and molding device, comprising a base, a material cylinder fixedly connected to the top of the base by a support rod, a lower mold fixedly connected to the top of the base by bolts, a pressing mechanism installed on the top of the base, a pressure plate installed on the surface of the pressing mechanism, a feeding mechanism installed at the bottom of the material cylinder, an ejection mechanism installed on the surface of the base, and a stabilizing mechanism installed on the surface of the pressure plate.
[0007] The pressing mechanism includes a guide plate, a crossbar, a connecting rod, a moving frame, and a hydraulic cylinder; the feeding mechanism includes a cylinder, a feeding hopper, a motor, a rotating rod, and a partition; the ejection mechanism includes a U-shaped plate, a square rod, and a top plate; and the stabilizing mechanism includes a groove, a round rod, a round block, and a spring.
[0008] Preferably, there are four guide plates, which are fixedly connected to the front and rear sides of the top of the base respectively; there are two crossbars, which are slidably inserted into the inner cavity of the guide plates respectively; the upper end of the connecting rod is welded to the surface of the crossbar; the lower end of the connecting rod is welded to the top of the pressure plate; there are two pressure plates; there are two movable frames, which are movably sleeved on the surfaces at both ends of the two crossbars respectively; there are two hydraulic cylinders, which are fixedly connected to the front and rear sides of the bottom of the material cylinder respectively; and the output end of the hydraulic cylinder is fixedly connected to the top of the movable frame by bolts.
[0009] Preferably, the top of the cylinder is connected to the bottom of the material cylinder, one side of the motor is fixedly connected to the back of the cylinder by bolts, the rotating shaft of the motor passes through the inner cavity of the material cylinder and is fixedly connected to the rear end of the rotating rod, the front end of the rotating rod is rotatably embedded in the front of the cylinder by bearings, there are several partitions, all of which are welded to the surface of the rotating rod, and the top of the hopper is connected to the bottom of the cylinder.
[0010] Preferably, the two ends of the U-shaped plate are fixedly connected to the bottom of the two movable frames respectively, and the upper end of the square rod slides through to the top of the base and is fixedly connected to the bottom of the top plate.
[0011] Preferably, the groove is formed on the front and rear sides inside the pressure plate, and the two ends of the round rod slide through the pressure plate to extend into the inner cavity of the groove and are fixedly connected to one side of the round block. The spring is movably sleeved on the surfaces of the two ends of the round rod, and the two ends of the spring contact the surface of the round block and the inner wall of the groove, respectively.
[0012] Preferably, the inner wall of the material cylinder is equipped with an agitation mechanism, which includes a support plate, a second motor, a vertical rod, a stirring rod, spiral blades, and a scraper. Both ends of the support plate are welded to the inner wall of the material cylinder. One side of the second motor is fixedly connected to the top of the support plate by bolts. The rotating shaft of the second motor passes through the support plate and is fixedly connected to the upper end of the vertical rod. The stirring rod is sleeved and welded to the surface of the vertical rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model controls the operation of motor two to rotate the vertical rod, which in turn drives the rotation of the stirring rod, spiral blades and scraper to agitate the refractory material in the barrel, allowing it to be better discharged into the cylinder. The rotation of the spiral blades transports the refractory material in the barrel downward into the cylinder. By controlling the intermittent operation of motor one, the rotating rod and partition plate are driven to rotate intermittently. This has the advantage of being able to intermittently and equally discharge the refractory material in the barrel, so that the amount of refractory material discharged into the lower mold each time is similar, reducing the error of pressing and molding in the same batch.
[0016] 2. This utility model controls the retraction of the hydraulic cylinder to move the moving frame upward. Under the guidance and limiting action of the guide plate, the crossbar moves obliquely upward, which in turn moves the connecting rod and the two pressure plates obliquely upward, causing the two pressure plates to move away from each other. Under the action of the round rod, the two pressure plates are kept flush. The spring is compressed and the round block moves in the groove, thus having the advantage of being able to easily discharge the refractory material in the cylinder into the lower mold through the hopper. The extension of the hydraulic cylinder causes the two pressure plates to first move obliquely downward and combine together, and then move downward together to press the refractory material in the lower mold into shape. Then, the hydraulic cylinder is controlled to retract significantly. When the moving frame moves upward, it drives the U-shaped plate to move upward and contact the lower end of the square rod. Then, the square rod and the top plate move upward, thus having the advantage of being able to eject the pressed refractory material, making it convenient for operators to take out.

[0023] Please see Figure 1-Figure 5 A refractory material pressing and molding device includes a base 1, a material cylinder 2 fixedly connected to the top of the base 1 by a support rod, a lower mold 3 fixedly connected to the top of the base 1 by bolts, a pressing mechanism 4 installed on the top of the base 1, a pressure plate 5 installed on the surface of the pressing mechanism 4, a feeding mechanism 6 installed at the bottom of the material cylinder 2, an ejection mechanism 7 installed on the surface of the base 1, and a stabilizing mechanism 9 installed on the surface of the pressure plate 5.
[0024] The pressing mechanism 4 includes a guide plate 41, a crossbar 42, a connecting rod 43, a moving frame 44, and a hydraulic cylinder 45; the feeding mechanism 6 includes a cylinder 61, a feeding hopper 62, a motor 63, a rotating rod 64, and a partition 65; the ejection mechanism 7 includes a U-shaped plate 71, a square rod 72, and a top plate 73; and the stabilizing mechanism 9 includes a groove 91, a round rod 92, a round block 93, and a spring 94.
[0025] Please see Figure 1 and Figure 4 There are four guide plates 41, which are fixedly connected to the front and rear sides of the top of the base 1. By setting the guide plates 41, the crossbars 42 move along the holes on the guide plates 41 under the action of the moving frame 44. There are two crossbars 42, which are slidably inserted into the inner cavity of the guide plates 41. The upper end of the connecting rod 43 is welded to the surface of the crossbar 42, and the lower end of the connecting rod 43 is welded to the top of the pressure plate 5. By setting the pressure plate 5, when it moves upward and separates, it is easy to let the discharged refractory material fall into the lower mold 3, avoid it from accumulating in one place, and improve the pressing and forming effect. There are two pressure plates 5. There are two moving frames 44, which are movably sleeved on the surfaces of the two ends of the crossbars 42. There are two hydraulic cylinders 45, which are fixedly connected to the front and rear sides of the bottom of the material cylinder 2. The output end of the hydraulic cylinder 45 is fixedly connected to the top of the moving frame 44 by bolts.
[0026] Please see Figure 1 , Figure 2 and Figure 3 The top of the cylinder 61 is connected to the bottom of the material cylinder 2. One side of the motor 63 is fixedly connected to the back of the cylinder 61 by bolts. The rotating shaft of the motor 63 passes through the inner cavity of the material cylinder 2 and is fixedly connected to the rear end of the rotating rod 64. The front end of the rotating rod 64 is rotatably embedded in the front of the cylinder 61 through the bearing. There are several partitions 65, all of which are welded to the surface of the rotating rod 64. By setting the partitions 65, the refractory material in the material cylinder 2 is intermittently and evenly discharged under the action of its rotation. The top of the hopper 62 is connected to the bottom of the cylinder 61.
[0027] Please see Figure 1 , Figure 2 and Figure 4The two ends of the U-shaped plate 71 are fixedly connected to the bottom of the two movable frames 44 respectively. By setting the U-shaped plate 71, when the hydraulic cylinder 45 retracts and causes the two pressure plates 5 to move upward and separate, it continues to retract and causes the movable frame 44 to contact the square rod 72. Then, it pushes the square rod 72 and the top plate 73 to move upward. The upper end of the square rod 72 slides through to the top of the base 1 and is fixedly connected to the bottom of the top plate 73.
[0028] Please see Figure 4 and Figure 5 The groove 91 is formed on the front and rear sides inside the pressure plate 5. The two ends of the round rod 92 slide through the pressure plate 5 and extend into the inner cavity of the groove 91 and are fixedly connected to one side of the round block 93. By setting the round rod 92, the two pressure plates 5 are kept horizontal when moving with the crossbar 42. The spring 94 is movably sleeved on the surface of the two ends of the round rod 92. By setting the spring 94, the two pressure plates 5 are more stable when moving relative to each other under the action of its elastic force. The two ends of the spring 94 are in contact with the surface of the round block 93 and the inner wall of the groove 91, respectively. By setting the round block 93, the round rod 92 is limited to prevent it from falling off the pressure plate 5.
[0029] Please see Figure 1 and Figure 2 The inner wall of the material cylinder 2 is equipped with an agitation mechanism 8, which includes a support plate 81, a second motor 82, a vertical rod 83, a stirring rod 84, a spiral blade 85, and a scraper 86. Both ends of the support plate 81 are welded to the inner wall of the material cylinder 2. One side of the second motor 82 is fixedly connected to the top of the support plate 81 by bolts. The rotating shaft of the second motor 82 passes through the support plate 81 and is fixedly connected to the upper end of the vertical rod 83. The stirring rod 84 is sleeved and welded to the surface of the vertical rod 83.
[0030] Please see Figure 2 The spiral blade 85 is welded to the lower end of the vertical rod 83. By setting the spiral blade 85, the refractory material in the material cylinder 2 is conveyed downward into the cylinder 61 under its rotation. One end of the scraper 86 is fixedly connected to the surface of the stirring rod 84. By setting the scraper 86, the refractory material at the bottom of the material cylinder 2 is scraped under its rotation to prevent it from adhering and depositing.
[0031] In use, the vertical rod 83 is rotated by controlling the operation of motor 82, which in turn drives the stirring rod 84, spiral blade 85, and scraper 86 to rotate, agitating the refractory material in the material cylinder 2 and allowing it to be better discharged into the cylinder 61. The rotation of the spiral blade 85 transports the refractory material in the material cylinder 2 downward into the cylinder 61. By controlling the intermittent operation of motor 63, the rotating rod 64 and partition plate 65 are driven to rotate intermittently, which can intermittently and equally discharge the refractory material in the material cylinder 2, so that the amount of refractory material discharged into the lower mold 3 each time is similar, reducing the error of the same batch of pressing and molding. By controlling the retraction of hydraulic cylinder 45, the moving frame 44 is moved upward, and under the guidance and limiting action of guide plate 41, the horizontal rod 42 is tilted. The upward movement causes the connecting rod 43 and the two pressure plates 5 to move obliquely upward, moving the two pressure plates 5 away from each other. Under the action of the round rod 92, the two pressure plates 5 remain flush. The spring 94 is compressed and the round block 93 moves in the groove 91, which facilitates the discharge of the refractory material in the cylinder 61 into the lower mold 3 through the hopper 62. The extension of the hydraulic cylinder 45 causes the two pressure plates 5 to first move obliquely downward and combine together, and then move downward together to press the refractory material in the lower mold 3 into shape. Then, the hydraulic cylinder 45 is controlled to retract significantly. When the moving frame 44 moves upward, it drives the U-shaped plate 71 to move upward and contact the lower end of the square rod 72. Then, the square rod 72 and the top plate 73 move upward, which can push out the pressed refractory material, making it convenient for the operator to take it out.
[0032] In summary, this refractory material pressing and molding device, through the cooperation of base 1, material cylinder 2, lower mold 3, pressing mechanism 4, pressure plate 5, feeding mechanism 6, ejection mechanism 7 and stabilizing mechanism 9, solves the problems of not being able to feed refractory material intermittently and in equal amounts, resulting in large differences in the amount of refractory material discharged into the mold each time, and the inconvenience of better filling the mold with refractory material, requiring a pusher plate to push it.
