If the refractory bricks piled together for a long time are not removed, they may be damaged due to mutual squeezing or collision. Moving them to one side can avoid such unnecessary damage and ensure the quality of the refractory bricks.
[0027] The fixing device 52 includes a second push rod 521. When the second push rod 521 is moved downward by external power, it will drive the first rack 522 fixedly connected to the bottom to move together. The first rack 522 is meshed with gears 523 on both sides. When the two gears 523 rotate under the drive of the first rack 522, they will mesh with the second rack 526 connected to the outer surface of the rotating bottom and slide toward the middle on the sliding column 528. At this time, the clamping link 527 fixedly connected at one end of the bottom of the two second racks 526 can adjust different widths at will, which is convenient for grabbing and fixing refractory bricks. In summary, the refractory bricks are moved to one side after the molding and production is completed, which not only improves the production efficiency, facilitates management and use, but also reduces the risk of damage and optimizes the production environment.
