Description

Technical Field

[0001] The utility model relates to the technical field of high-alumina brick production, in particular to a forming mold for high-alumina brick production. Background Art

[0002] High-alumina bricks are a type of refractory material primarily composed of Al₂O₃. Those with an Al₂O₃ content exceeding 90% are called corundum bricks. Due to varying resource requirements, standards vary from country to country. They are primarily used for lining blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary kilns.

[0003] The known authorized patent with application number: CN202022778537.4 discloses a special forming mold for the production of high-alumina bricks. Its background technology raises the problem that "the existing special forming mold for the production of high-alumina bricks is too simple in structure and inconvenient to demold, which greatly wastes labor, reduces the efficiency of production and processing, and affects the quality of processing. At the same time, the manufacturing cost must also be considered." To this end, the technical solution to this problem is "including a lower mold and an upper pressure plate, the lower mold is located directly below the upper pressure plate, and a mold groove is provided at the upper center of the lower mold, and the upper center of the upper pressure plate is fixedly connected to a mounting sleeve, and four vertically symmetrically arranged positioning rods are respectively fixedly connected to the four corners of the upper side of the lower mold, and the four positioning rods are respectively extended upward through the side walls of the upper pressure plate at one end away from the lower mold and are fixedly connected to two symmetrically arranged fixing plates" etc.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: although the demoulding effect of high-alumina bricks is achieved through the provided technical solution, it is not convenient to compact and defoam the high-alumina brick raw materials injected into the mold during use. When the raw materials are filled in the mold, the raw materials may not be densely combined due to the presence of air, resulting in honeycomb and other phenomena, which can easily affect the molding effect of the high-alumina bricks, thereby reducing the production quality and efficiency of the high-alumina bricks.

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0023] Example 1

[0024] Reference Figure 1-4 As shown, a forming mold for the production of high-alumina bricks includes: a lower mold 1, an inner cavity is opened in the lower mold 1, and a demoulding mechanism for ejecting the material is provided inside the inner cavity; an upper pressing plate 2 is arranged above the lower mold 1, and the upper pressing plate 2 is raised and lowered by a moving mechanism provided on the lower mold 1; a guide rail 3 fixedly mounted on one side of the lower mold 1; a slider 4 slidably engaged with the surface of the guide rail 3; a rack 5 fixedly mounted on one side of the slider 4; a collision plate 6 fixedly connected to both ends of the rack 5; a fixed block 7 fixedly mounted on one side of the lower mold 1; a spring 8 fixedly connected to one side of the fixed block 7 and one end of which is connected to a collision plate 6; and a driving mechanism provided on the lower mold 1 for moving the rack 5.

[0025] The driving mechanism includes a mounting block 9 fixedly mounted on one side of the lower mold 1, a motor 10 fixedly mounted on one side of the mounting block 9, and a half gear 11 fixedly connected to the output end of the motor 10 and meshing with the rack 5. Rubber pads 12 are fixedly mounted on the opposite surfaces of the two collision plates 6.

[0026] The technical solution provided by this embodiment is as follows: when in use, the raw materials are filled into the cavity of the lower mold 1, and then the motor 10 drives the half gear 11 to rotate, and the half gear 11 drives the rack 5 and the slider 4 to move to one side along the guide rail 3. At this time, one of the two collision plates 6 will knock on one side of the lower mold 1 and compress the spring 1 8. Under the action of the rubber pad 12, the collision plate 6 can be prevented from causing damage to the lower mold 1. At the same time, the other collision plate 6 is away from the lower mold 1. When the half gear 11 and the rack 5 are separated, the spring 1 8 rebounds, causing the collision plate 6 away from the lower mold 1 to rebound and knock on the other side of the lower mold 1, and the other is away from the lower mold 1. This is repeated to generate vibration in the lower mold 1, and thus the raw materials inside it will not generate bubbles. Therefore, the raw materials inside the lower mold 1 are compacted and defoamed, avoiding the occurrence of honeycomb bubbles in the raw materials and affecting the quality of high-alumina brick molding, ensuring that the raw materials can be densely combined, and effectively improving the production effect and efficiency of high-alumina bricks. After defoaming, the upper pressing plate 2 is driven downward by the moving mechanism to cooperate with the lower mold 1 to carry out the high-alumina brick molding operation.

[0027] Preferably: the demoulding mechanism includes an elastic component arranged in the inner cavity of the lower mold 1, a movable plate 13 arranged on the elastic component in an inverted T shape and slidingly connected to the lower mold 1, a demoulding plate 14 fixedly connected to the top of the movable plate 13, a linkage bent rod 15 symmetrically fixedly installed on both sides of the movable plate 13 and slidingly connected to the lower mold 1, and a locking component arranged on the lower mold 1 for limiting the demoulding plate 14, the top end of the linkage bent rod 15 extends out of the inner cavity of the lower mold 1, the inner bottom wall of the lower mold 1 is provided with a groove that cooperates with the demoulding plate 14, and the side of the demoulding plate 14 is fixedly provided with a sealing ring 18 that cooperates with the groove.

[0028] The elastic component includes two sets of fixed rods 16 symmetrically fixedly installed inside the inner cavity of the lower mold 1, and a second spring 17 sleeved on the surface of the fixed rod 16. The movable plate 13 is slidably connected to the surface of the fixed rod 16, and the two ends of the second spring 17 are respectively connected to the movable plate 13 and the bottom wall of the inner cavity.

[0029] The locking component includes a connecting block 23 fixedly connected to the top of a group of linked curved rods 15, a clamping block 24 rotatably connected to a side of the connecting block 23, and a limiting column 25 fixedly installed on a side of the lower mold 1 and engaged with the clamping block 24. A sunken groove that cooperates with the connecting block 23 is provided on the top of the lower mold 1. In order to ensure the stability of the stripping plate 14, locking components can be provided on both groups of linked curved rods 15.

[0030] The locking block 24 is rotated to engage with the limiting post 25 so as to limit the stripping plate 14 and finally fill the raw material in the lower mold 1. After defoaming, the upper pressing plate 2 is driven by the moving mechanism to move downward and contact the lower mold 1, and the high-aluminum brick can be formed in the lower mold 1. After forming, the upper pressing plate 2 is driven upward and separated from the lower mold 1 by the moving mechanism, and then the locking block 24 is rotated to separate from the limiting post 25. At this time, the linkage bent rod 15 loses its restriction and is driven by the spring 2 17 to move up and reset, thereby driving the stripping plate 14 to move upward and eject the high-aluminum brick blank formed in the lower mold 1, thereby achieving the stripping effect, simpler operation, and saving manpower.

[0031] Preferably, the moving mechanism includes a fixing frame 19 fixedly mounted on the top of the lower mold 1 , and a hydraulic cylinder 20 fixedly mounted on the top of the fixing frame 19 , the output end of the hydraulic cylinder 20 moves through the fixing frame 19 , and the upper pressing plate 2 is fixedly connected to the output end of the hydraulic cylinder 20 .

[0032] Specifically, during the forming process, the hydraulic cylinder 20 is used to drive the upper pressing plate 2 to move up and down, so that the upper pressing plate 2 and the lower mold 1 can cooperate to complete the forming work.

[0033] Example 2

[0034] Based on Example 1, in this embodiment: two guide rods 21 slidably connected to the fixing frame 19 are symmetrically fixed on the top of the upper pressure plate 2, and the surface of the guide rod 21 is provided with a spring three 22 whose two ends are respectively connected to the fixing frame 19 and the upper pressure plate 2.

[0035] The technical solution provided by this embodiment is: during the lifting and lowering process of the upper pressure plate 2, the guide rod 21 can be driven to slide up and down on the fixed frame 19 to ensure the lifting and lowering stability of the upper pressure plate 2 and the accuracy of the fitting. At the same time, the spring three 22 can be deformed, and the downward pressure of the upper pressure plate 2 can be buffered by the spring three 22, and its elastic force can be used to facilitate the separation of the upper pressure plate 2 and the lower mold 1.

[0036] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
