[0049] This demolding equipment for refractory brick production uses an electric push rod 12 to drive a rack 13 to move horizontally. Through meshing with a gear 14, the rack 13 rotates, causing the transmission roller 15 to rotate. This, in turn, drives the forming mold 16 to rotate within the groove 20, achieving a flipping motion. The piston rod of the second cylinder 17 pushes the ejector pin 18 upwards, passing through the partition plate 19 to eject the refractory brick formed in the mold, completing the demolding process. This structure ensures smooth demolding of the refractory bricks, reduces manual intervention, lowers the labor intensity of workers, and improves demolding efficiency and quality. It also prevents damage to the refractory bricks due to improper demolding. In addition, the motor 8 drives the lead screw 7 to rotate, causing the scraper 9 to move under the guidance of the guide rod 10. This quickly discharges excess waste material from the forming mold into the discharge hopper, ensuring the accuracy of the raw material quantity in the mold, improving the forming quality of the refractory bricks, reducing waste pollution to the working environment, and increasing work efficiency.

[0051] Workbench 1: As the basic support structure of the entire equipment, it is used to support other components and provide a stable platform for the operation of the equipment.

[0052] Support 2: Fixed on the workbench 1, mainly used to support the first cylinder 3, provide it with an installation position, and guide and limit the stamping block 4 through four uprights, so as to ensure the stability and accuracy of the stamping block 4 during the up and down movement.

[0053] First cylinder 3: Installed on the top plate of bracket 2, its piston rod can move up and down, pushing the stamping block 4 downward, and using the stamping block 4 to apply pressure to the material or mold placed on the worktable 1, so as to realize the pressing of the refractory brick blank and other related operations. After the pressing is completed, it can drive the stamping block 4 to rise and reset.

[0054] Stamping block 4: Connected to the lower end of the piston rod of the first cylinder 3, it slides up and down along the four uprights of the bracket 2 under the drive of the first cylinder 3. A spring 5 is installed on its lower surface. When stamping downwards, the spring 5 can buffer and adjust the stamping pressure through its elasticity to avoid excessive pressure from damaging the mold or blank. At the same time, after stamping is completed, the spring force of the spring 5 helps the stamping block 4 to quickly reset.

[0055] Spring 5: One end is fixed to the lower surface of the stamping block 4, and the other end is fixed to the upper surface of the worktable 1. Its main function is to buffer and dampen shocks during the stamping process, protect the equipment and mold, and help the stamping block 4 to quickly rebound after stamping, so as to carry out the next operation.

[0056] Vertical plate 6: Fixed on the upper surface of the worktable 1, used to support the upper surface of the lead screw worktable 1, to support the lead screw 7 and motor 8, to provide a fulcrum for the rotational connection of the lead screw 7, to ensure the stability of the lead screw 7 during rotation, and also to provide an installation position for the motor 8, so that the motor 8 can drive the lead screw 7 to rotate to drive other components to move.

[0057] Lead screw 7: Rotatably connected between the two vertical plates 6, with one end connected to the output end of the motor 8. When the motor 8 starts, it drives the lead screw 7 to rotate, and through threaded transmission, the scraper 9 sleeved on the lead screw 7 moves along the axial direction of the lead screw 7, thereby realizing the linear motion of the scraper 9, which is used to perform functions such as cleaning debris from the surface of the workbench.

[0058] Motor 8: Installed on the rear surface of the vertical plate 6, it provides power for the rotation of the lead screw 7. By controlling the start, stop, forward and reverse rotation and speed of the motor 8, the rotation of the lead screw 7 can be precisely controlled, thereby controlling the movement speed and position of the scraper 9.

[0059] Scraper 9: Screwed on lead screw 7. When lead screw 7 rotates, scraper 9 will move along the length of lead screw 7 due to the effect of thread transmission. Guide rod 10 is slidably sleeved inside to ensure the straightness and stability of scraper 9 during movement. Scraper 9 is mainly used to scrape away debris, dust or excess material on the surface of worktable 1, keep the surface of worktable clean, and prevent debris from affecting the placement of molds and the quality of products.

[0060] Guide rod 10: Fixedly installed on the opposite sides of the two upright plates 6 and slidably sleeved on the inner surface of the scraper 9. Its function is to provide guidance for the movement of the scraper 9, restricting the scraper 9 to only move in a straight line along the direction of the guide rod 10, avoiding wobbling or deviation of the scraper 9 during movement, and ensuring the accuracy and stability of its movement.

[0061] Slide 11: It is formed on the upper surface of the worktable 1 to cooperate with the movement of the transmission roller 15 and the forming mold 16, to provide guidance and support for their rotation and movement, and to ensure the positional accuracy and stability of the forming mold 16 during the working process.

[0062] Electric push rod 12: Fixed on the upper surface of the worktable 1, its output end is connected to the rack 13. Through the extension and retraction of the electric push rod 12, the rack 13 is driven to make linear motion, thereby providing power input for the rotation of the gear 14 and the transmission roller 15, realizing the rotation and position adjustment of the molding die 16.

[0063] Rack 13: Installed at the output end of electric push rod 12, meshing with gear 14. When electric push rod 12 pushes rack 13 to make linear motion, rack 13 will drive gear 14 to rotate, thereby converting the linear motion of electric push rod 12 into the rotational motion of gear 14 and transmission roller 15, realizing the transmission of power and the conversion of motion form.

[0064] Gear 14: meshes with rack 13, and a transmission roller 15 is fixedly sleeved on its inner surface. Under the drive of rack 13, it makes a circular motion, which in turn drives the transmission roller 15 to rotate. The transmission roller 15 drives the forming mold 16 fixed at its right end to rotate, realizing the angle adjustment and position change of the forming mold 16 during the working process.

[0065] Transmission roller 15: It is fixedly sleeved on the inner surface of gear 14 and rotatably connected in the inner wall of groove 20. Its main function is to transmit the rotation of gear 14 to molding mold 16, drive molding mold 16 to rotate, and at the same time provide support and positioning for molding mold 16 during rotation, so as to ensure that molding mold 16 can stably perform various operations.

[0066] Forming mold 16: Fixedly installed on the right end of the transmission roller 15 and rotatably connected to the inner wall of the groove 20. It is a key component for forming refractory bricks. The interior is used to place refractory materials. Through cooperation with other components, such as the stamping of the stamping block 4, the action of the second cylinder 17 and the ejector pin 18, the forming and demolding operations of the refractory brick blank are realized.

[0067] The second cylinder 17 is fixedly installed on the lower surface of the forming mold 16. Its piston rod penetrates into the inner surface of the forming mold 16. Its main function is to push the ejector pin 18 upward by extending the piston rod after the refractory brick blank is formed, so as to eject the formed refractory brick from the forming mold 16 and realize the demolding function.

[0068] Ejector pin 18: Fixedly installed at the upper end of the piston rod of the second cylinder 17. When the piston rod of the second cylinder 17 extends, the ejector pin 18 moves upward, passes through the partition plate 19, and ejects the refractory brick blank located in the forming mold 16, so that it is separated from the mold and the demolding process is completed.

[0069] Partition 19: Slidably sleeved on the outer surface of ejector pin 18 and fixedly installed in the inner wall of molding die 16. It mainly serves to isolate and limit, on the one hand dividing the internal space of molding die 16, and on the other hand limiting and guiding the movement of ejector pin 18, ensuring the accuracy and stability of ejector pin 18 during up and down movement, and preventing it from deviating or shaking.

[0070] Groove 20: It is formed on the upper surface of the worktable 1 to accommodate components such as transmission roller 15 and gear 14, providing space for their rotation, and at the same time playing a certain role in positioning and supporting these components to ensure their stability and accuracy during operation.

[0071] Discharge hopper 21: It is fixedly installed on the lower surface of the top plate of the workbench 1, and its output port is fixed on the inner surface of the vertical plate of the workbench 1.
