Description

Technical Field

[0001] This utility model belongs to the field of graphite electrode processing technology, specifically a mold for graphite electrode processing. Background Technology

[0002] Graphite electrodes are widely used in high-temperature and high-pressure industrial applications, and their processing places extremely high demands on the molds used. Traditional steel molds are prone to wear under high temperatures and pressures, affecting processing accuracy and efficiency. Therefore, modern molds for graphite electrode processing need to possess characteristics of high temperature resistance, wear resistance, and high precision, combined with advanced cooling systems and intelligent control technologies, such as sensor monitoring and automatic adjustment. In recent years, the application of innovative technologies such as composite materials, CNC technology, and nano-coatings has improved the performance and service life of molds. In the future, the combination of intelligent and green manufacturing technologies will further optimize the efficiency and environmental friendliness of graphite electrode processing.

[0003] However, in practical use, existing solutions often encounter difficulties in demolding. This difficulty reduces production efficiency, increases labor intensity and operational risks, leads to accelerated mold wear and shortened lifespan, and increases maintenance costs. Furthermore, demolding problems can cause damage or deformation of the graphite electrodes, affecting product quality and even production stability and delivery time. Therefore, designing molds that facilitate easy demolding is crucial for improving both efficiency and quality.

[0004] Therefore, this utility model provides a mold for processing graphite electrodes. Utility Model Content

[0038] Example 1:

[0039] like Figures 1 to 7As shown, the present invention provides a die for processing graphite electrodes, comprising a first fixed frame 1, a compression assembly on the inner side of the top of the first fixed frame 1, and a first support plate 2 fixedly connected to the inner side of the middle of the first fixed frame 1, which supports and fixes the first support plates 2 on both sides. A limit frame 21 is fixedly connected to the top of the first support plate 2, which supports and fixes the limit frame 21. A fixed ring 23 is rotatably connected to the inner side of the limit frame 21, which limits the fixed ring 23 to rotate within the limit frame 21. A motor 22 is fixedly connected to the outer left end of the left limit frame 21, which fixes the motor 22. The output end of the motor 22 is fixedly connected to the fixed ring 23, which fixes the left side of the fixed ring 23 and drives the fixed ring 23 to rotate. A die assembly is provided inside the fixed ring 23.

[0040] The compression assembly includes a first hydraulic rod 11. The first hydraulic rod 11 is fixedly connected to the inner side of the top of the first fixing frame 1. The first hydraulic rod 11 is fixed by the first fixing frame 1. The output end of the first hydraulic rod 11 is fixedly connected to a stamping piston 12. The stamping piston 12 is fixed by the first hydraulic rod 11, and the stamping piston 12 is driven to rise and fall by the first hydraulic rod 11.

[0041] The mold assembly includes a mold 3. A fixing ring 23 is fixedly connected to the inner side of the mold 3, and the fixing ring 23 fixes the mold 3. The fixing ring 23 drives the mold 3 to rotate via a motor 22. A second hydraulic rod 31 is fixedly connected to the bottom end of the mold 3, and the mold 3 fixes the second hydraulic rod 31. A second support plate 32 is fixedly connected to the output end of the second hydraulic rod 31, and the second support plate 32 is fixed via the second hydraulic rod 31. At the same time, the second hydraulic rod 31 drives the second support plate 32 to rise and fall. The second support plate 32 is slidably connected to the mold 3, and the mold 3 limits the second support plate 32. As a result, the first hydraulic rod 11 drives the stamping piston 12 to move downward, compressing the graphite material inside the mold 3. After the compression is completed, the fixing ring 23 drives the mold 3 to rotate forward via the motor 22, and the second support plate 32 moves forward via the second hydraulic rod 31, thereby pushing out the graphite electrode 7 for demolding.

[0042] A second fixed frame 4 is fixedly connected to the middle of the rear side of the first fixed frame 1. The second fixed frame 4 is fixed by the first fixed frame 1. A limit plate 41 is fixedly connected to the middle of the bottom of the second fixed frame 4. The limit plate 41 is fixed by the second fixed frame 4. A slot 42 is provided in the middle of the limit plate 41. The limit plate 41 is engaged with the second fixed frame 4. The slot 42 is engaged with the mold 3. When the mold 3 is in a vertical state, the slot 42 supports and engages the mold 3. When the mold 3 is in a horizontal state, the limit plate 41 engages and limits the mold 3, thereby limiting the rotation angle of the mold 3.

[0043] The first fixed frame 1 has evenly distributed hinges 5 fixedly connected to the front right side. The hinges 5 are fixed by the first fixed frame 1. The front end of the hinges 5 is rotatably connected to the support frame 51. The support frame 51 is fixed by the hinges 5. Thus, the first fixed frame 1 and the support frame 51 are connected by the hinges 5. The support frame 51 can rotate at the front end of the first fixed frame 1 by the hinges 5. The middle of the left rear end of the support frame 51 is fixedly connected to the spring pin 6. The spring pin 6 is fixed by the support frame 51.

[0044] A locking frame 61 is fixedly connected to the middle of the left front end of the first fixing frame 1. The locking frame 61 is fixed by the first fixing frame 1. The locking frame 61 is engaged with the spring pin 6. The rotation angle of the support frame 51 is fixed by the mutual engagement of the spring pin 6 and the locking frame 61.

[0045] The support frame 51 is fixedly connected to the left and right opposite slide rails 52, and the support frame 51 fixes the slide rails 52. The middle outer side of the slide rails 52 is slidably connected to the front and back opposite sliders 53, and the slide rails 52 limit the sliders 53. The sliders 53 are fixedly connected to the inner side of the sliders 53, and the sliders 53 fix the sliders 54.

[0046] A graphite electrode 7 is engaged with the top inner side of the holding rack 54, and the holding rack 54 supports the graphite electrode 7.

[0047] Working principle: When the die for processing graphite electrodes is running, the motor 22 first drives the fixed ring 23 to rotate, which in turn drives the die 3 to rotate forward by 45 degrees, thereby feeding graphite raw material into the die 3. Then, the motor 22 drives the die 3 to reverse, so that the die 3 engages with the slot 42, making the die 3 fit snugly against the slot 42. Then, the first hydraulic rod 11 drives the stamping piston 12 to move downward and enter the die 3, thereby compressing the graphite raw material inside the die 3. After compression, the motor 22, using the fixed ring 23, drives the die 3 to rotate forward, turning the entire die 3 horizontally. The mold 3 is engaged by the limiting plate 41, and then the second hydraulic rod 31 drives the second support plate 32 to extend to the front end, thereby pushing the compressed graphite electrode 7 forward. The graphite electrode 7 is placed in the holding rack 54. Then, the motor 22 drives the mold 3 to rotate 45 degrees backward and feeds the graphite raw material inward for compression. Then, the spring pin 6 is rotated to release the engagement between the holding rack 61 and the spring pin 6, so that the support rack 51 can rotate through the hinge 5. Then, the holding rack 54 is pulled to the front end, and the graphite electrode 7 is moved outward by the slide rail 52 and the slider 53 to remove the graphite electrode 7.
