[0013] By adopting the above technical solution, the ejection structure can be used to realize the ejection and discharge process of the finished product.

[0014] Preferably, the ejection structure includes a push block, which is a cylindrical structure. The lower surface of the push block is fixedly connected to the upper surface of the telescopic rod. The lower surface of the telescopic rod is fixedly installed on the upper surface of the base. A magnetic ring is fixedly installed on the lower surface of the push block. An electromagnet is arranged below the magnetic ring. The electromagnet is annular and is sleeved on the outer surface of the telescopic rod.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a forming machine for producing graphite electrodes, including a base 1, a worktable 2, a support column 3, a cylinder 4, a connecting plate 5, a punch 6, a connecting ring 7, a die 8, a bottom plate 9, a support cylinder 10, a driven ring 11, a drive wheel 12, a motor 13, a push block 14, a telescopic rod 15, a magnetic ring 16, an electromagnet 17, a moving contact 18, and a fixed contact 19.

[0031] The base 1 is hollow inside and has a circular structure. A cylindrical groove is provided on the upper surface of the base 1. A worktable 2 is provided above the base 1. The worktable 2 is a circular plate. A support column 3 is fixedly installed on the inner wall of the groove of the base 1. A cylinder 4 is fixedly installed on the outer surface of the support column 3. A connecting plate 5 is fixed to the output end of the cylinder 4. A connecting ring 7 is fixed to the side surface of the connecting plate 5. The connecting ring 7 is slidably sleeved on the outer surface of the support column 3. A punch 6 is fixed to the lower surface of the connecting plate 5. A die 8 is aligned below the punch 6. The die 8 is embedded and fixed to the surface of the worktable 2. A rectangular through hole is provided through the bottom surface of the die 8. The through hole on the bottom surface of the die 8 is aligned with the rectangular through hole on the surface of the worktable 2. A base plate 9 is slidably installed on the inner wall of the die 8. The die 8 and the base plate 9 are arranged in a ring on the surface of the worktable 2 in 4 sets.

[0032] like Figure 1 and Figure 2 As shown, during the graphite electrode forming process using this device, the raw material for graphite electrode forming is injected into the cavity 8, causing the raw material to move to the bottom of the cylinder 4 along with the rotating worktable 2. The cylinder 4 is activated, and the output end of the cylinder 4 drives the connecting plate 5 to move downward. The connecting plate 5 drives the punch 6 on the surface to move downward. The punch 6 engages with the cavity 8 downward. Under the action of the cavity 8, the base plate 9, and the pressurized punch 6, the graphite raw material is extruded and formed. The cavity 8 and the base plate 9 are arranged in a ring on the surface of the worktable 2 in four sets. While the cylinder 4 is activated to form one set of cavity 8, the other cavity 8 can simultaneously perform the unloading of finished products and the loading of raw materials, increasing the efficiency of graphite electrode forming.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, an angle adjustment structure is provided below the worktable 2. The angle adjustment structure realizes the horizontal angle adjustment process of the die 8 through the motor 13. The angle adjustment structure includes a support cylinder 10, which is a cylindrical structure that runs vertically through the worktable 2. The upper surface of the support cylinder 10 is fixedly connected to the lower surface of the worktable 2. The lower surface of the support cylinder 10 is rotatably mounted on the bottom surface of the groove of the base 1. A driven ring 11 is fixedly mounted on the outer surface of the support cylinder 10. A toothed block is provided on the outer surface of the driven ring 11. A drive wheel 12 is provided on one side of the driven ring 11. The drive wheel 12 is a gear structure. The drive wheel 12 meshes with the driven ring 11. The drive wheel 12 is fixedly connected to the output end of the motor 13. The motor 13 is fixedly mounted on the lower surface of the base 1.

[0034] During the angle adjustment of the die 8, the motor 13 is started. The motor 13 drives the drive wheel 12 to rotate. The rotation of the drive wheel 12 drives the driven ring 11 to rotate. The rotating driven ring 11 drives the support cylinder 10 to rotate inside the groove of the base 1, thereby driving the worktable 2 to rotate. The rotating worktable 2 drives the die 8 on the surface to adjust the angle in the horizontal direction, so that the die 8 in different states is aligned with the punch 6 connected to the cylinder 4, and different operations are performed on the graphite raw material simultaneously, increasing the efficiency of graphite forming.

[0035] The upper surface of the base 1 is provided with an ejection structure. The ejection structure uses a moving pusher block 14 to eject the base plate 9 for easy material discharge. The ejection structure includes a pusher block 14, which is cylindrical. The lower surface of the pusher block 14 is fixedly connected to the upper surface of the telescopic rod 15. The lower surface of the telescopic rod 15 is fixedly installed on the upper surface of the base 1. A magnetic ring 16 is fixedly installed on the lower surface of the pusher block 14. An electromagnet 17 is arranged below the magnetic ring 16. The electromagnet 17 is annular. An electromagnet 17 is fixedly installed on the upper surface of the base 1 via a bracket on the outer surface of the telescopic rod 15. The magnetic poles of the electromagnet 17 and the magnetic ring 16 repel each other. The coil on the surface of the electromagnet 17 is connected to the fixed contact 19 via a wire. The fixed contact 19 is fixedly installed on the outer surface of the support column 3. A movable contact 18 is provided above the fixed contact 19. The movable contact 18 is fixedly connected to the surface of the connecting ring 7. The movable contact 18 is connected to an external power source via a wire. Both the movable contact 18 and the fixed contact 19 are made of conductive materials.

[0036] like Figure 5 and Figure 6As shown, when the cylinder 4 on one side drives the punch 6 to descend to press the finished product, the cylinder 4 simultaneously drives the connecting ring 7 to slide downward. The sliding connecting ring 7 drives the moving contact 18 on the surface to move downward, so that the moving contact 18 contacts the fixed contact 19. When the moving contact 18 contacts the fixed contact 19, the electromagnet 17 is energized to generate a magnetic field. The electromagnet 17 and the magnetic ring 16 generate a thrust due to the repulsion of their magnetic poles, pushing the push block 14 to move upward. At this time, the telescopic rod 15 extends, and the moving push block 14 passes through the through hole on the lower surface of the die 8 and pushes the base plate 9 upward. The base plate 9 drives the finished product after surface forming to move out of the die 8, which facilitates the unloading of the finished product.

[0037] Working principle: When using this graphite electrode production molding machine, the cylinder 4 drives the connecting plate 5 to move up and down along the support column 3, thereby driving the punch 6 and the die 8 to cooperate in extruding the graphite raw material. The motor 13 is started, and the motor 13 drives the drive wheel 12 to rotate. The rotating drive wheel 12 drives the driven ring 11 to rotate, and finally drives the support cylinder 10 to rotate. The rotation of the support cylinder 10 causes the die 8 on the surface to adjust its angle. While the cylinder 4 is pressing downward on one side, the moving contact 18 on the other side moves downward synchronously and contacts the fixed contact 19. After the electromagnet 17 is energized, it generates a thrust due to the repulsion of the magnetic poles with the magnetic ring 16, which drives the push block 14 to move upward, pushing the formed graphite electrode out of the die 8, which is convenient for unloading and increases the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
