DETAILED DESCRIPTION

[0021] The utility model will be described in further detail in combination with the drawings and specific implementation manners:

[0022] For example, Figures 1 to 8As shown, an extrusion forming device for fine structure graphite products, comprising an extruder body 1 and two forming dies, the discharge pipe 2 of the extruder body 1 faces forward and its outer side is fixedly sleeved with a back plate 3. The back plate 3 is horizontally fixed with guide rails 4 on the upper and lower ends of the front side in the left-right direction, and the left and right sides of the two guide rails 4 are slidably provided with electric sliding blocks 5. The front end of each electric sliding block 5 is horizontally fixed with a first hydraulic cylinder 6 in the front-back direction, and the piston rod of each first hydraulic cylinder 6 faces forward and the piston rods of the two first hydraulic cylinders 6 on the same side are fixedly connected with the same support plate 7. The front end of the discharge pipe 2 of the extruder body 1 is fixedly provided with a first flange 8, and the top and bottom ends of the first flange 8 are provided with first fixed grooves 9. The front side of the back plate 3 on the upper and lower sides of the first flange 8 is fixedly provided with a vertically arranged second hydraulic cylinder 10, and the piston rod of the second hydraulic cylinder 10 is fixedly connected with a U-shaped fixed block 11 in the direction of the first flange 8. The two forming dies are a round forming die 12 and a square forming die 13, and the round forming die 12 and the square forming die 13 each comprise a butt joint section 14, a transition section 15 and a forming section 16 from back to front. The longitudinal section of the forming section 16 of the round forming die 12 is circular, the longitudinal section of the forming section 16 of the square forming die 13 is square, and the two forming sections 16 are respectively fixedly arranged at the center of the two support plates 7. The rear end of the two butt joint sections 14 is fixedly provided with a second flange 17, and the top and bottom ends of the second flange 17 are provided with second fixed grooves 18. The two butt joint sections 14 can abut against the front end of the discharge pipe 2 of the extruder body 1, the second flange 17 can abut against the first flange 8, and the two ends of the fixed block 11 can correspond to and be connected with the adjacent first fixed groove 9 and second fixed groove 18 by insertion;

[0023] In the initial state, the round forming die 12 is located at the left side of the back plate 3, and the square forming die 13 is located at the right side of the back plate 3. When it is needed to process a square carbon green body, the two electric sliding blocks 5 on the right side are operated to move left along the corresponding guide rails 4, so that the corresponding square forming die 13 can be driven to move close to the discharge pipe 2 of the extruder main body 1 until the die is moved to the front of the discharge pipe 2. Then, the two first hydraulic cylinders 6 are operated to retract the piston rods, so that the corresponding support plates 7 and the square forming die 13 can be driven to move backward until the butt joint section 14 of the square forming die 13 abuts against the front end of the discharge pipe 2, at which time the second flange 17 can abut against the first flange 8. Next, the two second hydraulic cylinders 10 are operated to extend the piston rods, so that the corresponding fixed blocks 11 can be driven to move towards the first flange 8 and the second flange 17 until the two ends of the fixed blocks 11 are inserted into the corresponding first fixed slots 9 and second fixed slots 18, and the first flange 8 and the second flange 17 are inserted and fixed, so that the connection between the square forming die 13 and the discharge pipe 2 is completed, and the connection is stable and does not affect the subsequent use. After that, the extruder main body 1 is operated to cooperate with the square forming die 13, so that a square carbon green body can be processed. When it is needed to process a round carbon green body, the two second hydraulic cylinders 10 are operated to retract the piston rods in the stopped state, so that the fixed blocks 11 can be driven to retreat to the original position, thereby releasing the insertion and fixation of the first flange 8 and the second flange 17. Then, the two first hydraulic cylinders 6 are operated to extend the piston rods, so that the square forming die 13 can be driven to move forward and separate from the discharge pipe 2. Next, the two electric sliding blocks 5 are operated to move right again, so that the square forming die 13 can be reset.
