Description

Technical Field

[0001] This utility model relates to the field of refractory material processing technology, specifically a pressing mold for manufacturing refractory materials. Background Technology

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The metallurgical industry has the largest usage, accounting for 50% to 60% of the total output. Refractory materials need to be pressed and shaped using pressing molds during the manufacturing process.

[0003] A search revealed that the announcement number CN218170780U, titled "A Pressing Mold for Refractory Material Production," includes a lower mold and a control box. Research and analysis showed that by pushing a button to move the mold, the upper and lower molds can be automatically connected and locked, greatly increasing the stability of the connection and ensuring the material is pressed and formed. However, it still has the following drawbacks to some extent.

[0004] For example, pressed finished products are inconvenient to demold. After pressing, the finished products may stick to the inside of the mold, making them difficult to remove. Workers need to use tools to pry them open, but this may damage the product. At the same time, manual demolding is inefficient and wastes unnecessary manpower. In order to solve the above technical problems, we have designed a pressing mold for the manufacture of refractory materials. Utility Model Content

[0005] The purpose of this utility model is to provide a pressing mold for the manufacture of refractory materials, which has the advantages of convenient demolding and saving manpower. It solves the problem that the finished product may stick to the inside of the mold after pressing, making it difficult to remove. Workers need to use tools to pry it open, but this may damage the product. At the same time, manual demolding is inefficient and wastes unnecessary manpower.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressing mold for manufacturing refractory materials, comprising a base plate, with upright plates fixedly welded to the left and right sides of the top of the base plate, and a top plate fixedly welded to the top of the upright plates. A lower mold is rotatably mounted on the middle of the opposite side of the upright plates via a rotating rod. A motor is fixedly mounted on the right side of the right upright plate, and the output shaft of the motor is fixedly connected to the rotating rod on the right side of the lower mold. An angle sensor is fixedly mounted on the surface of the rotating rod on the left side of the upright plate. Vibration components are fixedly mounted on the left and right sides of the bottom of the lower mold, each vibration component including a spring. The spring is fixedly mounted on the bottom of the lower mold, and a support plate is fixedly connected to the bottom of the spring. A second motor is fixedly installed on the top plate. A shaped block is fixedly installed on the output shaft surface of the second motor. A hydraulic cylinder is fixedly installed at the center of the top of the top plate. The telescopic end of the hydraulic cylinder extends through to the bottom of the top plate and is fixedly installed with an upper mold. Connecting plates are fixedly installed on the front and rear sides of the left and right sides of the upper mold. A pressure plate is fixedly installed at the bottom of the connecting plate. Support components are fixedly installed on the front and rear sides of the upright plate. The support components include a limiting sleeve. The limiting sleeve is fixedly welded to the surface of the upright plate. A fixing plate is fixedly installed on the top of the limiting sleeve. A displacement plate is provided through the inner cavity of the limiting sleeve. A second spring is fixedly installed on one side of the top of the displacement plate. The other end of the second spring is fixedly installed on the surface of the fixing plate.

[0007] Preferably, the rotating rods on both sides of the upright plate are rotatably connected to the upright plates on both sides via bearings, and the lower mold and the upper mold are matched.

[0008] Preferably, limit posts are fixedly installed at the four corners of the top of the lower mold, and limit grooves are formed at the four corners of the bottom of the upper mold, with the positions of the limit grooves corresponding to the positions of the limit posts.

[0009] Preferably, the bottom of the pressure plate is configured as an arc surface, the outer side of the top of the displacement plate is configured as a slope, and the surface of the displacement plate is in sliding contact with the connection between the limiting sleeve and the displacement plate.

[0010] Preferably, the bottom of the pressure plate is in sliding contact with the inclined surface of the top of the displacement plate, and the top of the displacement plate is in sliding contact with the bottom of the lower mold.

[0011] Preferably, the top of the second motor does not contact the bottom of the lower mold, and the surface of the irregular block is in sliding contact with the bottom of the lower mold.

[0012] Preferably, a cushioning pad, made of sponge material, is fixedly adhered to the center of the top of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The present invention uses a hydraulic cylinder to drive the upper mold for automatic pressing. During the downward movement, the connecting plate drives the pressure plate to press against the displacement plate, pushing it inward and supporting it under the lower mold. The support force of the displacement plate on the lower mold improves the stability of the lower mold during the pressing process, effectively ensuring the qualified rate of the pressed product.

[0015] 2. This utility model uses a motor to drive the lower mold to rotate, so that the product rotates automatically after pressing. This eliminates the need for manual operation during demolding. The product's own weight after flipping, combined with the motor driving the irregular block to rotate, causes it to continuously strike the bottom of the lower mold. This causes the lower mold to automatically fall onto the buffer pad after flipping, achieving an automatic demolding effect. It eliminates the need for manual demolding, saving workers' time and energy, and is highly practical. Attached Figure Description

[0024] Please see Figure 1-7A pressing mold for manufacturing refractory materials includes a base plate 1. Vertical plates 4 are fixedly welded to the left and right sides of the top of the base plate 1. A top plate 9 is fixedly welded to the top of the vertical plates 4. A lower mold 3 is rotatably mounted on the middle of the opposite side of the vertical plates 4 via a rotating rod. A motor 15 is fixedly mounted on the right side of the right vertical plate 4. The output shaft of the motor 15 is fixedly connected to the rotating rod on the right side of the lower mold 3. An angle sensor 14 is fixedly mounted on the surface of the rotating rod on the left side of the vertical plate 4. By setting the angle sensor 14, the rotation angle of the lower mold 3 can be detected, allowing workers to quickly observe the rotation of the lower mold 3. Vibration components 13 are fixedly mounted on the left and right sides of the bottom of the lower mold 3. The vibration components 13 include a spring 134. By setting the spring 134, a second motor 131 can be elastically supported, causing the second motor 131 to make a short-range displacement when the irregular block 132 contacts the lower mold 3, preventing the irregular block 132 from jamming. The spring 134 is fixedly mounted on the bottom of the lower mold 3. A support plate 133 is fixedly connected to the bottom of spring 134. A motor 131 is fixedly mounted on the surface of the support plate 133. A shaped block 132 is fixedly mounted on the surface of the output shaft of motor 131. A hydraulic cylinder 8 is fixedly mounted at the center of the top of the top plate 9. The telescopic end of the hydraulic cylinder 8 extends through to the bottom of the top plate 9 and is fixedly mounted on the upper mold 7. Connecting plates 10 are fixedly mounted on the left and right sides and the front and rear sides of the upper mold 7. A pressing plate 6 is fixedly mounted on the bottom of the connecting plate 10. A pressing plate 6 is fixedly mounted on the front and rear sides of the upright plate 4. The support assembly 5 includes a limiting sleeve 51, which is fixedly welded to the surface of the upright plate 4. A fixing plate 54 is fixedly installed on the top of the limiting sleeve 51. By setting the limiting sleeve 51, the displacement plate 52 can be supported, allowing it to slide laterally and preventing the displacement plate 52 from shaking. The displacement plate 52 is provided through the inner cavity of the limiting sleeve 51. A second spring 53 is fixedly installed on one side of the top of the displacement plate 52, and the other end of the second spring 53 is fixedly installed on the surface of the fixing plate 54.

[0025] Please see Figure 1 The rotating rods on both sides of the upright plate 4 are rotatably connected to the upright plates 4 on both sides through bearings, and the lower mold 3 and the upper mold 7 are matched.

[0026] Please see Figure 1 and Figure 2 Limiting posts 11 are fixedly installed at the four corners of the top of the lower mold 3, and limiting grooves 12 are opened at the four corners of the bottom of the upper mold 7. The position of the limiting grooves 12 corresponds to the position of the limiting posts 11. By setting the limiting grooves 12 and the limiting posts 11, it can be ensured that the upper mold 7 and the lower mold 3 can correspond exactly, thereby improving the precision of the product pressing process.

[0027] Please see Figure 1 , Figure 2 and Figure 3The bottom of the pressure plate 6 is set with an arc surface structure, which allows the pressure plate 6 to better contact the displacement plate 52, thereby making it more stable in pushing the displacement plate 52. The outer side of the top of the displacement plate 52 is set with a sloping structure, and the surface of the displacement plate 52 is in sliding contact with the connection between it and the limiting sleeve 51.

[0028] Please see Figure 3 The bottom of the pressure plate 6 is in sliding contact with the inclined surface of the top of the displacement plate 52, and the top of the displacement plate 52 is in sliding contact with the bottom of the lower mold 3.

[0029] Please see Figure 4 and Figure 5 The top of motor 131 does not contact the bottom of the lower mold 3, and the surface of the irregular block 132 is in sliding contact with the bottom of the lower mold 3.

[0030] Please see Figure 1 and Figure 2 A cushioning pad 2 is fixedly glued to the center of the top of the base plate 1. The cushioning pad 2 is made of sponge material. By setting the cushioning pad 2, the product can be cushioned when it falls, so as to avoid bumping the product.

[0031] In use, the product to be pressed is placed inside the lower mold 3. Then, the hydraulic cylinder 8 is activated, and its telescopic end extends, causing the upper mold 7 to move downwards. This, in turn, causes the connecting plate 10 and the pressure plate 6 to move downwards. When the upper mold 7 moves down close to the lower mold 3, the bottom of the pressure plate 6 contacts the inclined surface of the displacement plate 52. During the downward movement of the pressure plate 6, the displacement plate 52 is pushed inwards, and the spring 2 53 is compressed, thus moving it below the lower mold 3. When the upper mold 7 contacts the lower mold 3 to press the product, the bottom of the lower mold 3 is supported by the displacement plate 52. Figure 3 As shown, this allows the lower mold 3 to provide stable support during product pressing. After product pressing is completed, the hydraulic cylinder 8 is reset, causing the upper mold 7 to rise to its original position. During the rising process, the pressure plate 6 gradually disengages from the displacement plate 52. At this time, the second spring 53 resets, causing the displacement plate 52 to disengage from below the lower mold 3, thus preventing obstruction of the bottom of the lower mold 3. Then, the first motor 15 is started, driving the lower mold 3 to rotate through its output shaft. The rotation angle of the lower mold 3 is detected by the angle sensor 14 until it rotates 180°. Then, the first motor 15 is stopped, and the second motor 131 is started, driving the irregular block 132 to rotate through its output shaft. This causes the protruding part of the irregular block 132 to continuously contact and strike the surface of the lower mold 3. The first spring 134 cushions the impact, allowing the first motor 15 to move autonomously during the striking process. The lower mold 3 vibrates when struck, and combined with the product's own weight, the product quickly falls to the top of the buffer pad 2, where workers can then remove it directly.

[0032] In summary, this pressing mold for refractory material manufacturing, through the cooperation of the lower mold 3, support component 5, pressure plate 6, upper mold 7, hydraulic cylinder 8, vibration component 13, angle sensor 14, and motor 15, solves the problem that finished products may stick to the inside of the mold after pressing, making them difficult to remove. This requires workers to use tools to pry them open, which may damage the product. At the same time, manual demolding is inefficient and wastes unnecessary manpower.
