The ejection of the mold is convenient. The reciprocating opening and closing of the upper die base 2 on the lower die base 1 is realized. The opening and closing operation is stable. The opening and closing of the mold are combined with the ejection of the mold to realize the opening and ejection of the formed mold and the pushing of the material during the closing of the mold, making the ejection of the formed refractory bricks convenient, and the mold structure is simple.

[0022] Specifically, the opening and closing mechanism includes a threaded sleeve 8, a guide rail groove 9, a first threaded rod 10 and a first motor 11. Threaded sleeves 8 are provided at the bottom of the upper die base 2 on opposite sides of the groove 6. The threaded sleeves 8 are provided at one end of the bottom of the upper die base 2. Guide rail grooves 9 are provided at the top of the lower die base 1 on opposite sides of the lower die core 3. A first threaded rod 10 is provided inside the guide rail groove 9. The threaded sleeve 8 is arranged in the guide rail groove 9 and is threadedly connected to the first threaded rod 10. One end of the first threaded rod 10 is connected to the output end of the first motor 11 through a coupling. The first motor 11 drives the first threaded rod 10 in the guide rail groove 9 to rotate. The threaded sleeve 8 on the first threaded rod 10 drives the upper die base 2 to move on the top of the lower die base 1. The upper die base 2 is moved to the side of the lower die base 1 away from the feeding plate 12, that is, the mold is opened. The first motor 11 drives the upper die base 2 to reset. The upper die base 2 moves and resets on the lower die base 1, and the upper die base 2 and the lower die base 1 are closed for mold closing, that is, the mold is closed.

[0023] Further, a material guiding plate 12 is provided at the upper end of the lower die base 1 close to the threaded sleeve 8. The material guiding plate 12 is arranged in an inclined structure to facilitate the formed refractory bricks on the lower die base 1 to slide out for discharging.

[0024] Further, the material injection channel 5 is arranged in an inclined structure. The end of the material injection channel 5 close to the groove 6 is set at a lower inclination. The forming pressing plate 7 is movably arranged above the outlet of the material injection channel 5 inside the groove 6. The end of the material injection channel 5 far from the groove 6 is connected to a material injection machine through a material injection pipe. The material injection pipe adopts a corrugated pipe, which facilitates rapid injection of materials from the material injection channel 5 into the lower die core 3. During the material injection process, the forming pressing plate 7 does not affect the material injection operation of the material injection channel 5.

[0025] Further, the ejection mechanism includes an ejection plate 13, a second threaded rod 14, a second motor 15, a connecting plate 16 and ejection rods 17. An ejection plate 13 is arranged inside the lower die core 3. A second threaded rod 14 is arranged inside the lower die base 1 below the lower die core 3. The bottom of the second threaded rod 14 is connected to the output end of the second motor 15 inside the lower die base 1 through a coupling. A connecting plate 16 is arranged on the second threaded rod 14 through a screw sleeve. Ejection rods 17 are arranged at the tops of opposite ends of the connecting plate 16. The tops of the ejection rods 17 are connected to the bottom of the ejection plate 13 through ejection holes. The second motor 15 drives the second threaded rod 14 to rotate. The connecting plate 16 on the second threaded rod 14 moves upward. The ejection rods 17 on the connecting plate 16 move upward. The ejection rods 17 push the ejection plate 13 inside the lower die core 3 upward to eject the formed refractory bricks inside the lower die core 3.

[0026] Further, the top height of the ejection plate 13 ejected inside the lower die core 3 is set at the same plane height as the top of the lower die base 1, so that the formed refractory bricks inside the lower die core 3 can be completely ejected and then smoothly pushed out for discharging by the reset-moving upper die base 2.

[0027] Furthermore, vacuum suction cups are provided at the four corners of the bottom of the lower die base 1 through installation grooves. The vacuum suction cups fix the lower die base 1 to make the mold stable and reliable during use.

[0028] The usage method of this embodiment is as follows: Inject the refractory brick forming material into the lower die core 3 of the lower die base 1 through the material injection channel 5. It is also possible to move the upper die base 2 on the lower die base 1 away and directly add the material into the lower die core 3. During the forming process, the upper die base 2 and the lower die base 1 are closed. Under the action of the hydraulic cylinder 4, the hydraulic cylinder 4 pushes the forming pressure plate 7 in the groove 6 to move downward through the hydraulic rod. The forming pressure plate 7 enters the lower die core 3 and extrudes the material in the lower die core 3. After the forming is completed, the hydraulic cylinder 4 resets, and the forming pressure plate 7 moves upward back into the groove 6. The first motor 11 drives the first threaded rod 10 in the guide rail groove 9 to rotate. The threaded sleeve 8 on the first threaded rod 10 drives the upper die base 2 to move on the top of the lower die base 1, and the upper die base 2 is moved to the side of the lower die base 1 away from the material guiding plate 12. The second motor 15 drives the second threaded rod 14 to rotate, the connecting plate 16 on the second threaded rod 14 moves upward, the ejector rod 17 on the connecting plate 16 moves upward, and the ejector rod 17 pushes the ejector plate 13 in the lower die core 3 to move upward, ejecting the formed refractory brick in the lower die core 3, so that the height of the top of the ejector plate 13 is the same as the height of the top of the lower die base 1. Then the first motor 11 drives the upper die base 2 to reset. The reset movement of the upper die base 2 on the lower die base 1 pushes the refractory brick ejected on the top of the lower die base 1, and the refractory brick is pushed by the upper die base 2 and slides out through the material guiding plate 12, completing the forming and discharging of the refractory brick, the reset and closing of the upper die base 2, realizing the extrusion forming of the refractory brick, the forming and ejection of the refractory brick, the convenient forming and ejection of the mold, realizing the reciprocating open and close die of the upper die base 2 on the lower die base 1, the stable open and close die operation, the combination of the open and close die and the ejection and discharging of the mold, realizing the open die, ejection, closing die and pushing material of the mold forming, making the forming and discharging of the refractory brick convenient, the mold structure simple, and the forming efficient.
