Description

Technical Field

[0001] The utility model relates to the field of refractory brick production equipment, in particular to a mold for producing acid-resistant checkered bricks. Background Art

[0002] Checker brick is a kind of refractory brick. Checker brick is mainly used in the upper and middle part of the heat storage chamber of the hot blast furnace to store heat. It plays an important role in heating cold air into hot air. The structure of the checker brick includes a checker brick shell and honeycomb holes distributed therein. The shell of the honeycomb ceramic checker brick can be a regular polygonal prism or a cylinder, and the cross-sectional shape of the honeycomb hole can be a regular polygon or a circle. Due to the special shape and the presence of honeycomb holes, it is easy for materials to remain in the mold during the production process, which affects the subsequent checker brick production. The existing mold is not convenient for cleaning the inside of the mold, so it is particularly necessary to develop a mold that is easy to clean the inside of the mold for producing checker bricks. Summary of the invention

[0003] The utility model aims to provide a mould for producing acid-resistant checkered bricks, which has the advantage of being easy to clean the inside of the mould for producing checkered bricks.

[0004] The technical solutions adopted are as follows:

[0005] A mold for producing acid-resistant checkered bricks includes a fixed mold and a pressing mold. The fixed mold is provided with a plurality of columns. The pressing mold is provided with a plurality of through holes corresponding to the columns one by one. A push plate is vertically slidably arranged in the fixed mold. The push plate is slidably connected to each column. A telescopic mechanism connected to the push plate is arranged below the fixed mold. A bracket is arranged at the upper end of the fixed mold. A drive motor is arranged at the upper end of the bracket. The drive motor includes a vertical drive shaft. The drive shaft is connected to a horizontally extending cleaning brush.

[0006] Preferably, a limiting ring is provided inside the fixed mold below the push plate.

[0007] Preferably, the limiting ring is separated from the inner wall of the fixed mold, and the lower end of the limiting ring is provided with an inclined beam connected to the fixed mold.

[0008] Preferably, the telescopic mechanism is a pneumatic telescopic rod.

[0009] Preferably, the upper end of the column is flush with the upper end of the fixed mold.

[0010] Compared with the prior art, the beneficial effects are:

[0011] 1. The utility model puts the material into the fixed mold, and uses the pressing die to press the material into shape. When demoulding, the pressing die rises, and the telescopic mechanism controls the push plate to rise to push out the checker bricks formed in the fixed mold. After the checker bricks are taken away, the driving mechanism drives the cleaning brush to brush the upper end surface of the push plate to remove the material remaining on the push plate to avoid affecting the next step of production.

[0012] 2. The limit ring of the utility model limits the lower limit position of the push plate, and the limit ring is separated from the inner wall of the fixed mold to prevent the material from falling onto the limit ring from the gap between the push plate and the fixed mold, thereby preventing the upper end surface of the limit ring from being uneven.

[0016] The present invention will be further described below in conjunction with specific embodiments. Figure 1 to Figure 2 As shown:

[0017] Embodiment 1: A mold for producing acid-resistant checkered bricks, comprising a fixed mold 1 and a pressing mold 2, wherein the pressing mold 2 is arranged directly above the fixed mold 1, wherein a plurality of columns 3 are arranged in the fixed mold 1, wherein a crossbeam 4 connected to each column 3 is arranged at the lower end of the interior of the fixed mold 1, wherein the pressing mold 2 is provided with a plurality of through holes 5 corresponding to each column 3 one by one, wherein a push plate 6 is arranged vertically in the fixed mold 1 for sliding movement, wherein the push plate 6 is slidably connected to each column 3, and wherein the push plate 6 is slidably connected to the inner wall of the fixed mold 1,

[0018] A telescopic mechanism 7 connected to the push plate 6 is provided below the fixed mold 1. The telescopic mechanism 7 controls the push plate 6 to rise and fall. When pressing checker bricks, the material is put into the fixed mold 1, and the pressing mold 2 is lowered to press the material into shape. When demoulding, the pressing mold 2 rises, and the telescopic mechanism 7 controls the push plate 6 to rise to push out the checker bricks formed in the fixed mold 1.

[0019] A bracket 10 is provided at the upper end of the fixed mold 1, and a driving motor 11 is provided at the upper end of the bracket 10. The driving motor 11 includes a vertical driving shaft 12, and the driving shaft 12 is connected to a horizontally extending cleaning brush 13. After the checkered bricks are removed, the driving mechanism drives the cleaning brush 13 to brush the upper end surface of the push plate 6 to remove the material remaining on the push plate 6;

[0020] Embodiment 2: A mold for producing acid-resistant checkered bricks, comprising a fixed mold 1 and a pressing mold 2, wherein the pressing mold 2 is arranged directly above the fixed mold 1, wherein a plurality of columns 3 are arranged in the fixed mold 1, wherein a crossbeam 4 connected to each column 3 is arranged at the lower end of the interior of the fixed mold 1, wherein the pressing mold 2 is provided with a plurality of through holes 5 corresponding to each column 3 one by one, wherein a push plate 6 is arranged vertically in the fixed mold 1 for sliding, wherein the push plate 6 is slidably connected to each column 3, wherein the push plate 6 is slidably connected to the inner wall of the fixed mold 1, wherein the upper end of the column 3 is flush with the upper end of the fixed mold 1,

[0021] A telescopic mechanism 7 connected to the push plate 6 is provided below the fixed mold 1. The telescopic mechanism 7 controls the push plate 6 to rise and fall. When pressing checker bricks, the material is put into the fixed mold 1, and the material is pressed and formed by descending the die 2. When demolding, the die 2 rises, and the telescopic mechanism 7 controls the push plate 6 to rise and push out the checker bricks formed in the fixed mold 1. A limit ring 8 is provided inside the fixed mold 1 below the push plate 6. The limit ring 8 limits the lower limit position of the push plate 6. The telescopic mechanism 7 is a pneumatic telescopic rod.

[0022] The limiting ring 8 is separated from the inner wall of the fixed mold 1, and the lower end of the limiting ring 8 is provided with an inclined beam 9 connected to the fixed mold 1 to prevent the material from falling into the limiting ring 8 from the gap between the push plate 6 and the fixed mold 1, thereby preventing the upper end surface of the limiting ring 8 from being uneven.

[0023] A bracket 10 is provided at the upper end of the fixed mold 1, and a drive motor 11 is provided at the upper end of the bracket 10. The drive motor 11 includes a vertical drive shaft 12, and the drive shaft 12 is connected to a horizontally extending cleaning brush 13. After the checker bricks are removed, the driving mechanism drives the cleaning brush 13 to brush the upper end surface of the push plate 6 to remove the material remaining on the push plate 6.

[0024] The specific working process is as follows: control the telescopic mechanism 7 to drive the push plate 6 to descend until the push plate 6 is pressed on the limit ring 8, put the material into the fixed mold 1, and use the pressing mold 2 to descend to press the material into shape. When demolding, the pressing mold 2 rises, and the telescopic mechanism 7 controls the push plate 6 to rise to push out the checker bricks formed in the fixed mold 1. After taking out the checker bricks, the driving mechanism drives the cleaning brush 13 to brush the upper end surface of the push plate 6, and then controls the push plate 6 to descend to carry out the next brick pressing procedure.
