[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Please see Figures 1 to 3 The present invention provides a technical solution including a main workbench 1, a mold 8 fixedly connected to the top center of the workbench 1, the mold 8 being made of iron material, T-shaped support columns 9 fixedly connected to both sides of the top of the workbench 1, the T-shaped support columns 9 being hollow, a motor 4 fixedly connected to the top of the T-shaped support columns 9, a cam 10 fixedly connected to the bottom end of the output shaft of the motor 4, a fixing rod 13 fixedly connected to one side of the T-shaped support column 9, an impact column 11 slidably connected to the surface of the fixing rod 13, a push column 3 fixedly connected to one side of the top of the impact column 11, the cam 10 contacting the push column 3, a spring 2 sleeved on the surface of the fixing rod 13, a spring 2 provided between the impact column 11 and the T-shaped support column 9, and one side of the impact column 11 penetrating through the T-shaped support column 9 and contacting the mold 8.

[0027] Specifically, before extruding the refractory bricks, the powdered raw material is poured into the mold 8, the switch of the motor 4 is closed, and the motor 4 drives the cam 10 to rotate. The push column 3 and the cam 10 are connected, causing the impact column 11 to slide on the surface of the fixed rod 13. The impact column 11 compresses the spring 2. When the cam 10 separates from the push column 3, the elasticity of the spring 2 can quickly drive the impact column 11 to impact the mold 8. Since the mold 8 is made of iron, the impact will cause the mold 8 to vibrate. The vibration will eliminate the gaps in the powdered raw material inside the mold 8, making the density distribution of the powdered raw material inside the mold 8 more compact.

[0028] Please see Figures 1 to 3 A fixed platform 5 is fixedly connected to the top of the T-shaped support column 9. Cylinders 6 are fixedly connected to both sides of the top of the fixed platform 5. The bottom end of the piston rod of the cylinder 6 passes through the fixed platform 5 and is fixedly connected to the model block 7.

[0029] Specifically, closing the switch of cylinder 6 causes the piston rod of cylinder 6 to move the mold block 7 downwards, and the extrusion of the mold block 7 causes it to extrude the powder material in the mold 8 into refractory bricks.

[0030] Please see Figures 4 to 6 The mold 8 has an internal mounting groove 17, which is an I-shaped groove. A rotating shaft 14 is fixedly connected to one side of the middle of the mounting groove 17. A pressure rod 12 is rotatably connected to the surface of the rotating shaft 14. One end of the pressure rod 12 passes through the mold 8. The mounting position of the rotating shaft 14 is offset from the center line of the pressure rod 12, so that the distance from the force application point of the pressure rod 12 to the rotating shaft 14 is four times the distance from the resistance point to the rotating shaft 14. A sliding groove is provided at one end of the front surface of the pressure rod 12. The bottom end of the sliding groove passes through the pressure rod 12. A moving plate 15 is slidably connected to the surface of the mounting groove 17. A cylindrical sliding column 18 is fixedly connected to the bottom end of the front surface of the moving plate 15. The sliding column 18 is embedded in the sliding groove and slides along the vertical direction of the sliding groove. A push plate 16 is fixedly connected to the top of the moving plate 15. The push plate 16 is on the same horizontal plane as the inner surface of the mold 8.

[0031] Specifically, after the refractory brick is formed, hold the pressure rod 12 and make it rotate counterclockwise around the rotating shaft 14. Through the cooperation between the sliding column 18 and the sliding groove, the sliding column 18 is moved upward. Through the cooperation between the moving plate 15 and the push plate 16, the refractory brick formed by the mold 8 can be pushed out by the push plate 16. Since the position of the rotating shaft 14 is at the ratio of the lever arm and the resistance arm of the pressure rod 12, and due to the principle of the force-saving lever, it is more effortless to push out the refractory brick by the pressure rod 12.

[0032] In use, before extruding the refractory bricks, the powdered raw material is poured into the mold 8. The switch of the motor 4 is closed, and the motor 4 drives the cam 10 to rotate. Through the cooperation between the push column 3 and the cam 10, the impact column 11 slides on the surface of the fixed rod 13. The impact column 11 compresses the spring 2. When the cam 10 separates from the push column 3, due to the elasticity of the spring 2, the impact column 11 can quickly impact the mold 8. Since the mold 8 is made of iron, the impact will cause the mold 8 to vibrate. The vibration eliminates the gaps in the powdered raw material inside the mold 8, making the density distribution of the powdered raw material inside the mold 8 more even. Tightly close the switch of cylinder 6. The piston rod of cylinder 6 drives the mold block 7 to move downward. The extrusion of the mold block 7 compresses the powder material in the mold 8 into refractory bricks. After the refractory bricks are formed, hold the pressure rod 12 and make it rotate counterclockwise around the rotating shaft 14. Through the cooperation between the sliding column 18 and the sliding groove, the sliding column 18 is moved upward. Through the cooperation between the moving plate 15 and the push plate 16, the push plate 16 can push out the refractory bricks formed in the mold 8. Since the position of the rotating shaft 14 is at the ratio of the lever arm and the resistance arm of the pressure rod 12, and due to the principle of the lever that saves effort, it is easier to push out the refractory bricks by the pressure rod 12.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
