Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to a high-alumina brick forming mold structure. Background Technology

[0002] High-alumina bricks, as an important refractory material, are widely used in metallurgy, chemical industry, building materials and many other fields. In the production process of high-alumina bricks, the performance of the forming mold plays a crucial role in the quality and production efficiency of the bricks.

[0003] Traditional high-alumina brick forming molds have several significant drawbacks. First, the stamping process generates substantial amounts of dust, which not only severely pollutes the production environment and harms the health of operators but also potentially leads to the loss of high-alumina brick raw materials, affecting product quality stability. Second, existing molds are not convenient or efficient enough for demolding, impacting production efficiency. For example, some molds have poorly designed ejection structures, which can easily damage high-alumina bricks during ejection, increasing the defect rate. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes a high-alumina brick forming mold structure.

[0005] A high-alumina brick forming mold structure includes:

[0006] A bottom mold is fixed on a forming table. The bottom mold is provided with a forming groove, and the bottom of the forming groove is provided with a top block that can move up and down.

[0007] An upper die is installed at the lower end of the stamping mechanism. A pressure block adapted to the forming groove is provided on the lower side of the upper die for stamping the raw material placed in the forming groove. A dust removal mechanism is provided on the upper die.

[0008] The dust removal mechanism includes a barrier made of flexible material, the upper end of which is fixed to the lower side of the upper mold and surrounds the pressure block.

[0009] More preferably, the bottom mold has a surrounding groove on its upper side, the surrounding groove is a closed loop groove and is arranged around the forming groove, and the lower end of the barrier can fall into the surrounding groove.

[0010] More preferably, the lower end of the enclosure is provided with a rigid retaining ring adapted to the enclosure groove, and the retaining ring can fall into the enclosure groove.

[0011] More preferably, the dust removal mechanism further includes a plurality of dust removal holes disposed on the upper mold and a dust removal box located on the upper side of the upper mold. The plurality of dust removal holes are evenly distributed on the outer side of the forming groove, and the dust removal box is located on the upper side of the dust removal holes and communicates with them. The dust removal box is connected to a dust collection device through a dust removal pipe.

[0012] In a further preferred embodiment, the top block is controlled to rise and fall by a lifting mechanism, the output end of which passes through the bottom of the forming groove and is connected to the top block. The lower side of the top block is provided with multiple sliding rods, which slide in cooperation with the bottom of the forming groove.

[0013] More preferably, the enclosure is a canvas curtain with a fixing ring at its upper end, which is fixed to the lower side of the upper mold by bolts.

[0014] Beneficial effects:

[0015] 1. High-efficiency dust removal: This invention constructs a comprehensive dust removal system through the combination of enclosures, dust collection holes, dust collection boxes, and dust collection equipment. The enclosures form an initial barrier in the stamping area, reducing dust spillage; the dust collection holes suck in some dust, which is then collected in the dust collection box and discharged by the dust collection equipment, effectively reducing dust pollution during the production process, improving the production environment, protecting the health of operators, and also reducing raw material loss, which helps to improve product quality stability.

[0016] 2. Convenient demolding: The lifting mechanism precisely controls the raising and lowering of the top block, and the sliding cooperation between the slide bar and the bottom of the forming groove ensures that the top block is stable and evenly stressed when ejecting the high alumina brick, which greatly reduces the probability of damage to the high alumina brick during demolding, improves demolding efficiency and product yield, and thus improves overall production efficiency.

[0017] 3. Good adaptability: The various components of this mold structure are reasonably designed and have a certain adaptability to the production of high alumina bricks of different specifications. For example, by adjusting the stroke of the lifting mechanism, it can meet the demolding requirements of high alumina bricks of different thicknesses. The standardized design of components such as the enclosure and pressing block means that when producing high alumina bricks of different sizes, only some key components need to be replaced, without replacing the entire mold, which reduces production costs and improves production flexibility.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] like Figures 1-5 The high-alumina brick forming mold structure shown includes a bottom mold 1, an upper mold 2, and a dust removal mechanism disposed on the upper mold 2.

[0026] Bottom mold 1: Bottom mold 1 is fixed on the forming table. A forming groove 3 is provided on bottom mold 1. The forming groove 3 is the key part of the forming of high alumina brick raw material. A top block 4 that can move up and down is provided at the bottom of the forming groove 3. The lifting mechanism 14 controls the lifting and lowering of the top block 4. The output end of the lifting mechanism 14 passes through the bottom of the forming groove 3 and is connected to the top block 4. This connection method allows the lifting mechanism 14 to accurately control the lifting and lowering of the top block 4. At the same time, multiple sliding rods 16 are also provided on the lower side of the top block 4. The sliding rods 16 slide and cooperate with the bottom of the forming groove 3. The setting of the sliding rods 16 can not only enhance the stability of the top block 4 during the lifting and lowering process, avoid the top block 4 from deflecting during the rising or falling process, ensure that the high alumina brick is subjected to uniform force when demolding, and reduce the damage of high alumina brick caused by uneven ejection, but also guide the movement of the top block 4, making the lifting and lowering of the top block 4 smoother.

[0027] Upper die 2: Upper die 2 is installed at the lower end of the stamping machine 15. A pressure block 6 is provided on its lower side. The pressure block 6 is adapted to the forming groove 3. When the raw material is put into the forming groove 3, the upper die 2 moves downward under the action of the stamping mechanism, and the pressure block 6 stamps the raw material into shape.

[0028] Dust removal mechanism: The dust removal mechanism includes a barrier 7 made of flexible material. The upper end of the barrier 7 is fixed to the lower side of the upper mold 2 and surrounds the pressure block 6. The barrier 7 can effectively block the spread of dust during the stamping process and reduce the pollution of dust to the production environment. Specifically, when the pressure block 6 stamps the raw material, the barrier 7 will move closer to the forming groove 3 as the upper mold 2 descends, surrounding the stamping area and forming a relatively closed space, thereby greatly reducing the possibility of dust spreading outward. Furthermore, the upper side of the bottom mold 1 is provided with a surrounding groove 5. The surrounding groove 5 is a closed loop groove and surrounds the forming groove 3. The lower end of the barrier 7 can fall into the surrounding groove 5. This design makes the barrier 7 and the bottom mold 1 form a tighter fit, further enhancing the dust blocking effect.

[0029] In addition, the lower end of the enclosure 7 is provided with a rigid retaining ring 13 that is adapted to the enclosure groove 5. The retaining ring can fall into the enclosure groove 5. The enclosure groove 5 adopts an inverted trapezoidal open structure, which facilitates the rigid retaining ring 13 to fall into the enclosure groove. The rigid retaining ring 13 can not only enhance the stability of the lower end of the enclosure 7 and prevent the enclosure 7 from deforming due to airflow impact during the stamping process, but also better cooperate with the enclosure groove 5 to improve the sealing performance.

[0030] Further dust removal design: The dust removal mechanism also includes multiple dust removal holes 9 set on the upper mold 2 and a dust removal box 8 located on the upper side of the upper mold 2. The multiple dust removal holes 9 are evenly distributed on the outside of the forming groove 3. The dust removal box 8 is located on the upper side of the dust removal holes 9 and communicates with them. The dust removal box 8 is connected to a dust collection device through a dust removal pipe 10. During the stamping process, the dust generated is blocked by the enclosure 7 and is sucked into the dust removal box 8 through the dust removal holes 9, thereby achieving a more efficient dust removal effect.

[0031] The specific implementation of the enclosure 7: The enclosure 7 is a canvas curtain with a fixing ring 11 at the upper end. The fixing ring 11 is fixed to the lower side of the upper mold 2 by bolts 12. The canvas curtain is soft, low cost and durable, which can meet the requirements of blocking dust during the stamping process. The installation and disassembly of the enclosure 7 are convenient through the cooperation of the fixing ring 11 and the bolts 12, and it is easy to replace the enclosure 7 in time when it is damaged.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
