[0002] A graphite electrode is a solid electrode composed of carbon elements, with characteristics such as high electrical conductivity, corrosion resistance, and good mechanical strength. It is usually made of petroleum coke and pitch coke as aggregates and coal tar pitch as a binder through a series of complex technological processes (such as raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization, and machining). Such electrodes can be made of natural graphite or artificial graphite and can be used in extreme environments such as high temperature, high pressure, and strong current. After the graphite electrode is processed and formed by the existing forming die for graphite electrode processing, the formed graphite electrode needs to be ejected. The existing ejection structure and forming structure of the graphite electrode processing die need to be driven by multiple power sources, which is not conducive to the use of the graphite electrode processing die.

[0026] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a graphite electrode processing mold, including: a support frame 1; a support base 2 fixedly connected to the inner side of the support frame 1; a support top frame 3 fixedly connected to the top of the support base 2; a mold base 4 fixedly connected to the top of the support top frame 3, and a plurality of mold cavities 5 are equidistantly opened at the top of the mold base 4; an ejector pin 23 is slidably arranged equidistantly inside the mold cavity 5, and the ejector pin 23 is slidably arranged with the support top frame 3; a moving disk 9 is fixedly connected to the bottom end of the ejector pin 23, a support column 19 is fixedly connected to the bottom of the moving disk 9, the support column 19 is slidably arranged with the support base 2, a moving plate 18 is slidably arranged inside the support base 2, and the bottom end of the support column 19 is fixedly connected to the moving plate 18; pull rods 6 are symmetrically fixedly connected to the top of the moving plate 18, the pull rods 6 are slidably connected to the support base 2, and the pull rods 6 are slidably connected to the support top frame 3.

[0027] It can be understood that in the present utility model, during the forming of the graphite electrode, it is controlled by an externally connected controller, powered on by an externally connected power supply, the raw material is injected into each cavity 5 of the mold base 4. The output end of the air cylinder 12 drives the moving slide plate 8 to move. The moving slide plate 8 slides on the outside of the pull rod 6. The moving slide plate 8 drives the upper mold plate 13 and the punch post 14 to move downward. The punch post 14 enters the cavity 5 to form the graphite electrode. After forming, coolant is injected into the spiral temperature-conducting water pipe 15 through the liquid inlet pipe 16 to cool the mold base 4 and the cavity 5, and cool the formed graphite electrode. The output end of the air cylinder 12 drives the moving slide plate 8, the upper mold plate 13 and the punch post 14 to move upward. When the moving slide plate 8 moves to the bottom position of the limiting plate 10 and continues to move upward, the moving slide plate 8 pulls the pull rod 6 to move upward through the limiting plate 10. When the pull rod 6 moves upward, it drives the moving plate 18 in the support base 2 to move upward. When the moving plate 18 moves upward, it drives the support column 19 and the moving disk 9 to move upward. The moving disk 9 drives the ejector pin 23 to move upward, and the ejector pin 23 is used to eject the graphite electrode in the cavity 5, facilitating the removal of each graphite electrode in the cavity 5. When the moving disk 9 moves upward, it drives the upper guiding columns 20 to move upward. When the guiding columns 20 move upward, the springs 22 in the guiding cylinders 21 are compressed. When the output end of the air cylinder 12 drives the moving slide plate 8 to move downward, the springs 22 will drive the guiding columns 20, the moving disk 9 and the support column 19 to reset, thereby driving the ejector pin 23 to reset, facilitating the use of the mold for the next time.
