Abstract
Description
Technical Field
[0001] This utility model relates to the field of fused zirconia-corundum brick technology, and in particular to molds for fused zirconia-corundum bricks. Background Technology
[0002] Fused zirconia-corundum bricks have wide applications in many high-temperature industrial fields. Their production quality is crucial to the stability and efficiency of related industrial production. As a key piece of equipment in the production of fused zirconia-corundum bricks, the performance of the mold directly affects the quality of the bricks and production efficiency. During the manufacturing process of fused zirconia-corundum bricks, the mold needs to withstand high temperature, high pressure, and complex physicochemical environment. The mold usually consists of an outer liner and an inner liner. The inner liner needs to be replaced after a period of use, and the inside of the mold needs to be kept clean to avoid impurities affecting the quality of the bricks. This places high demands on the design of the mold, which must facilitate the disassembly and assembly of the inner liner and effectively clean the inside of the mold to ensure the smooth progress of the production process and the high quality of the product.
[0003] In previous technologies related to fused zirconia-corundum brick molds, the structural design of the molds was relatively traditional. For mold fixing, bolts were often used to connect the various components together. For the installation of the mold liner, simple slots were often set on the outer mold liner or the liner was placed directly in a specific position, and then additional fixing devices, such as metal clips, were used, or some adhesive material was filled between the outer and inner mold liners to prevent the liner from moving. When cleaning the inside of the mold, some designs required manual disassembly of parts of the mold after a certain number of uses, and simple cleaning tools, such as brushes and small vacuum cleaners, to clean the inside of the mold. After cleaning, the mold was reassembled. These traditional methods can meet the basic usage requirements of the mold to a certain extent, but they have many inconveniences in actual operation.
[0004] In the current field of fused zirconia-corundum brick mold technology, there is a significant problem: the disassembly and assembly of the mold liner is not very convenient. When the liner needs to be replaced, multiple tools are usually required to complete the operation. During the disassembly process, the mold itself is prone to wear and tear, and the entire disassembly and assembly process is relatively time-consuming. This situation will affect production efficiency, especially in the context of large-scale production of fused zirconia-corundum bricks. Therefore, a mold for fused zirconia-corundum bricks is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a mold for fused zirconia corundum bricks, which aims to improve the problem of the inconvenience of replacing the inner liner in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A mold for fused zirconia-corundum bricks includes an outer mold liner, an inner mold liner inside the outer mold liner, a placement component inside the outer mold liner for placing the inner mold liner, a stabilizing component inside the outer mold liner, and a cleaning component inside the outer mold liner.
[0008] The stabilizing component includes a fixed column, both ends of which are fixedly connected to the inside of the outer mold liner. A slide rail is provided inside the outer mold liner. The outer wall of the fixed column is slidably connected to the inside of a slider. A spring is sleeved on the outer wall of the fixed column. One end of the spring is fixedly connected to the inner wall of the outer mold liner, and the other end of the spring is fixedly connected to the outer wall of the slider. A connecting block is fixedly connected to the outside of the slider. The outer wall of the connecting block is slidably connected to the inside of the slide rail. A clamp is fixedly connected to the outer wall of the connecting block.
[0009] As a further description of the above technical solution:
[0010] The placement component includes a placement drawer, which is formed inside the outer shell of the mold.
[0011] As a further description of the above technical solution:
[0012] The cleaning component includes a drive belt disposed inside the outer shell of the mold.
[0013] As a further description of the above technical solution:
[0014] The mold outer liner has a limiting groove inside, a ramp inside, and a placement groove inside;
[0015] As a further description of the above technical solution:
[0016] A connecting post is fixedly connected to the top of the transmission belt, and a limiting ring is fixedly connected to the outer wall of the connecting post;
[0017] As a further description of the above technical solution:
[0018] A second spring is sleeved on the outer wall of the connecting column. The bottom of the second spring is fixedly connected to the outer wall of the transmission belt, and a lifting plate is fixedly connected to the top of the second spring.
[0019] As a further description of the above technical solution:
[0020] The lifting plate is internally slidably connected to the outer wall of the connecting column, and a dust collection plate is rotatably connected to the outer wall of the lifting plate;
[0021] As a further description of the above technical solution:
[0022] A conduit is provided on the outer side of the dust collection plate, and the outer wall of the conduit is slidably connected to the inside of the placement groove. A roller is rotatably connected inside the dust collection plate, and the outer wall of the roller is slidably connected to the outer wall of the slope.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the clamp realizes its movement function by placing the mold inner liner. When the mold inner liner is placed, the mold inner liner drives the connecting block and the slider, and cooperates with the spring to clamp the mold inner liner, thereby facilitating the assembly and disassembly of the mold inner liner and maintaining its stability during operation. This solves the problem that the existing methods require multiple tools to be used for assembly and disassembly, which makes disassembly inconvenient and improves convenience.
[0025] 2. In this utility model, the dust-collecting plate moves by activating the transmission belt. When the transmission belt is activated, it drives the lifting plate and connecting column, and in conjunction with the second spring, moves the dust-collecting plate on the top of the mold, thereby cleaning the inside of the mold and keeping it clean. When not in use, it is recycled inside the mold and does not obstruct the pressure applied to the top. This solves the problem of dust entering the mold during molding and causing poor quality, thus improving product quality. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a mold for fused zirconia-corundum bricks, comprising an outer mold liner 1, which is typically made of a high-strength metal material, such as high-quality alloy steel. This material has good strength and toughness and can withstand the high temperature, high pressure and various mechanical stresses during the production process of fused zirconia-corundum bricks. An inner mold liner 3 is provided inside the outer mold liner 1. The inner mold liner 3 is generally made of a special ceramic material that is resistant to high temperature, wear-resistant and chemically stable, in order to adapt to the harsh conditions during the fusion casting process of fused zirconia-corundum bricks and ensure the forming quality of the brick. A placement component is provided inside the outer mold liner 1, which is used to place the inner mold liner 3. A stabilizing component is provided inside the outer mold liner 1. A cleaning component is provided inside the outer mold liner 1.
[0033] The stabilizing component includes a fixing column 5, both ends of which are firmly fixed to the inside of the mold outer liner 1 by a robust welding process or a high-precision mechanical connection. The fixing column 5 itself is made of a solid metal rod that has undergone special heat treatment, and has high strength and straightness. Both ends of the fixing column 5 are fixedly connected to the inside of the mold outer liner 1. A slide rail 9 is provided inside the mold outer liner 1. The outer wall of the fixing column 5 is slidably connected to the inside of the slider 12. A spring 13 is sleeved on the outer wall of the fixing column 5. One end of the spring 13 is fixedly connected to the inner wall of the mold outer liner 1, and the other end of the spring 13 is fixedly connected to the outer wall of the slider 12. A connecting block 10 is fixedly connected to the outside of the slider 12. The outer wall of the connecting block 10 is slidably connected to the inside of the slide rail 9. A clamp 11 is fixedly connected to the outer wall of the connecting block 10. The placement component includes a placement drawer 14, which is opened inside the mold outer liner 1.
[0034] Specifically, in the processing flow of fused zirconia-corundum bricks, the outer mold liner 1 is placed inside the processing table drawer 14. When the inner mold liner 3 is placed, the inclined top of the clamp 11 causes the inner mold liner 3 to exert a pushing force on the clamp 11, causing the clamp 11 to move. The clamp 11 then drives the connecting block 10 to move inside the slide rail 9. At the same time, the connecting block 10 drives the slider 12 to slide along the outer wall of the fixed column 5. During this process, the spring 13 is compressed by the slider 12 and contracts. After the inner mold liner 3 smoothly enters the drawer 14, the spring 13 rebounds with its own elasticity, tightly pressing against the inner mold liner 3 and firmly fixing it in the appropriate position for subsequent fused zirconia-corundum brick processing. The processing provides a stable working environment, ensuring stability at every stage of the process. This allows for quick replacement of inner liner sizes when producing different models of fused zirconia-corundum bricks, eliminating the need for complex disassembly and installation procedures and significantly reducing downtime. The stable inner liner also ensures uniform stress distribution throughout the fused zirconia-corundum brick during molding, preventing quality issues such as dimensional deviations and uneven density caused by inner liner movement or positional misalignment. Furthermore, the ease of inner liner replacement ensures stability and prevents the introduction of new error factors. Each replacement ensures consistent product quality, maintaining a consistently high level of product quality.
[0035] Reference Figure 1 - Figure 3 The cleaning component includes a drive belt 6, which is a ring-shaped belt made of high-strength, wear-resistant rubber material. Its surface has regularly arranged textures that increase friction with other components, ensuring stable power transmission. The drive belt 6 is located inside the outer mold liner 1, which has a limiting groove 4, a ramp 20, and a placement groove 8. A connecting post 19 is fixedly connected to the top of the drive belt 6. The connecting post 19 is a cylinder made of stainless steel with a finely polished surface to reduce friction with other components. A limiting ring 15 is fixedly connected to the outer wall of the column 19. A spring 18 is sleeved on the outer wall of the column 19. The bottom of the spring 18 is fixedly connected to the outer wall of the transmission belt 6. A lifting plate 17 is fixedly connected to the top of the spring 18. The lifting plate 17 is made of aluminum alloy, which ensures a certain strength while reducing the overall weight. The lifting plate 17 is slidably connected to the outer wall of the column 19. A dust suction plate 7 is rotatably connected to the outer wall of the lifting plate 17. A conduit 2 is provided on the outside of the dust suction plate 7. The outer wall of the conduit 2 is slidably connected to the inside of the placement groove 8. A roller 16 is rotatably connected to the inside of the dust suction plate 7. The outer wall of the roller 16 is slidably connected to the outer wall of the ramp 20.
[0036] Specifically, after the inner mold liner 3 is placed in the placement drawer 14, the transmission belt 6 can be activated. The transmission belt 6 drives the connecting column 19 to move, and the movement of the connecting column 19 in turn acts on the lifting plate 17, causing the lifting plate 17 to move vertically. The dust suction plate 7 is mounted on the lifting plate 17 and moves accordingly. During the movement of the dust suction plate 7, its internal rollers 16 guide it, allowing the dust suction plate 7 to slide on the top of the outer mold liner 1 for cleaning. As the dust suction plate 7 moves, when it encounters... When the slope is at 20, the roller 16 moves on the slope, causing the dust suction plate 7 to rise. The rise of the dust suction plate 7 drives the lifting plate 17 to rise synchronously, which in turn stretches the spring 18. During this process, the dust suction plate 7 thoroughly and meticulously cleans the inside of the outer mold liner 1 and the inner mold liner 3. After cleaning, the dust suction plate 7 returns, and the spring 18 rebounds, pulling the dust suction plate 7 back into the inner mold liner 1 to prevent it from protruding and hindering subsequent pressing and other operations, thus ensuring the smooth progress of the entire processing flow.
[0037] Working Principle: When processing fused zirconia-corundum bricks, the outer mold liner 1 is first placed on the processing table. Then, according to the processing shape, the inner mold liner 3 is placed inside the placement drawer 14. Because the top of the clamp 11 is inclined, the clamp 11 is pushed when the inner mold liner 3 is placed. Then, the clamp 11 drives the connecting block 10 to move inside the slide rail 9. Then, the connecting block 10 drives the slider 12 to slide on the outer wall of the fixed column 5, compressing the spring 13, thereby placing the inner mold liner 3 inside the placement drawer 14. Finally, the spring 13 rebounds and fixes the inner mold liner 3, maintaining its working stability. After completion, the transmission belt 6 can be started, which drives the connecting column 19 to move. Then, the connecting column 19 drives the lifting plate 17 to move. The lifting plate 17 then drives the dust suction plate 7 to move, and the rollers 16 inside the dust suction plate 7 guide it to move on the top of the outer mold liner 1. Then, due to the ramp 20, the dust suction plate 7 is raised, which drives the lifting plate 17 to rise, stretching the second spring 18, thereby cleaning the inside of the outer mold liner 1 and the inner mold liner 3. After that, it is put back, and the second spring 18 rebounds to make it return to the inside of the outer mold liner 1, preventing it from protruding and obstructing the pressing.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
