[0002] Castable refractory bricks are a type of special refractory material used in the steelmaking process under extremely high-temperature environments. They are primarily used in steelmaking furnaces, casting systems, and other areas requiring high temperatures to protect these facilities from molten metal and slag, and to maintain the stability of the production process. The production of castable refractory bricks typically involves steps such as raw material mixing, extrusion molding, drying, and firing. In the extrusion molding step, the use of a die-casting device is crucial. Applying pressure through the die-casting device ensures that the raw material is accurately molded in the mold, guaranteeing that the shape and size of each brick meet design standards and satisfy the installation and usage requirements of the steelmaking equipment.

[0025] The vibration assembly includes a housing 23, inside which a motor 8 is fixedly connected. The motor 8 provides power to the vibration assembly. An eccentric wheel 25 is fixedly connected to the output end of the motor 8. The eccentric wheel 25 provides the reciprocating force of the vibrating plate 24. A connecting rod 26 is fixedly connected to the outer wall of the eccentric wheel 25. A connecting piece 27 is rotatably connected to the outer wall of the connecting rod 26.

The vibrating plate 24 is used to vibrate the raw material of the lower mold 16 to make it evenly distributed. A connecting block 21 is fixedly connected to the side wall of the housing 23.

[0026] Reference Figure 4 The quick-release assembly includes a latch 17, the outer wall of which is slidably connected to the inside of the upper mold base 13. The latch 17 is used to press and release the upper mold 14. A spring 18 is provided on the outer wall of the latch 17. One end of the spring 18 is fixedly connected to the inner wall of the upper mold base 13, and the other end of the spring 18 is fixedly connected to a retaining plate 19.

[0027] Working principle: During operation, raw materials are poured into the feeding box 11. The hydraulic rod 29 extends, pushing the machine housing 23 (fixed at the output end) and the feeding box 11 forward. Simultaneously, the pulleys 22 at the bottom of the machine housing 23 and the feeding box 11 move on the guide rail 7 under the force of the hydraulic rod 29, causing the feeding box 11 to reach the position of the lower mold 16, achieving automatic feeding. After feeding is complete, the hydraulic rod 29 retracts, causing the vibrating plate 24 at the bottom of the machine housing 23 to reach directly above the lower mold 16. At this time, the drive motor 8 rotates, causing the eccentric wheel 25 (fixed at the output end) to rotate. Simultaneously, the connecting rod 22 connected to the outer wall of the eccentric wheel 25... 26 drives the connecting piece 27 to move horizontally up and down, and at the same time drives the bottom connected vibration plate 24 to punch and vibrate the lower mold 16 to make the internal raw material fully uniform and achieve the effect of raw material compaction.

At this time, control the hydraulic rod 312 to extend and drive the upper mold 14 connected to the output end to squeeze the raw material inside the lower mold 16 to achieve the effect of extrusion molding. After the extrusion is completed, control the hydraulic rod 312 to retract and reset, and at the same time control the hydraulic rod 16 to retract and drive the lower mold operating table to slide and rise on the connecting rod 13. The extruded refractory bricks are demolded under their own gravity.

[0028] Secondly, when it is necessary to change the upper mold 14 and the lower mold 16 to produce refractory bricks of different sizes, the upper mold 14 is pulled out from the upper mold base 13 by pressing the buckle 17 inward, and the spring 18 drives the clamping plate 19 to return to its original position. At the same time, the lower mold 16 is directly removed from the lower mold operating table 4 to achieve the effect of quick disassembly. During installation, the buckle 17 is pressed inward to drive the clamping plate 19 to return to its original position. The upper mold 14 is placed into the upper mold base 13 through the second limiting groove 20. At this time, the clamping plate 19 enters the first limiting groove 15 opened in the upper mold 14. The buckle 17 is released, and the spring 18 drives the clamping plate 19 to return to its original position to achieve the effect of fixation and achieve the effect of quick installation.
