The steps of taking out the lower mold are cumbersome, which increases the time for the staff to take out the lower mold, thereby reducing the efficiency of the device using the graphite mold for production. Therefore, a graphite mold auxiliary clamp is proposed to address the above problems. Utility Model Content

[0028] Example:

[0029] See also Figure 1-3 A graphite mold auxiliary fixture includes an operating table 1, a plurality of supporting legs 10 are fixedly connected to the bottom end of the operating table 1, a disc 14 is rotatably connected to the top end of the operating table 1, a motor 12 is fixedly connected to the bottom end of the operating table 1, an output end of the motor 12 passes through the operating table 1 and is fixedly connected to the bottom end of the disc 14, a lower mold 13 and a clamping assembly 2 are respectively arranged inside the disc 14, and the bottom end of the lower mold 13 abuts against the top end of the operating table 1;

[0030] See also Figure 1-3The clamping assembly 2 includes a plurality of placement grooves 24 opened inside the disc 14, the placement grooves 24 penetrate the upper mold 4 and are connected to the outside, a pair of clamping plates 21 are provided inside the plurality of placement grooves 24, the clamping plates 21 abut against the lower mold 13, a plurality of springs 22 are fixedly connected between the clamping plates 21 and the placement grooves 24, a plurality of telescopic rods 23 are fixedly connected between the clamping plates 21 and the placement grooves 24, the number of telescopic rods 23 and the number of springs 22 correspond one to one, the telescopic rods 23 are located on the inner side of the springs 22, the elastic force of the springs 22 is less than the gravity of the lower mold 13, the top end of the operating table 1 is fixedly connected with an L-shaped plate 3, the bottom end of the L-shaped plate 3 is fixedly connected with an electric telescopic rod 6, the output end of the electric telescopic rod 6 is fixedly connected with a carrier plate 5, the bottom end of the carrier plate 5 is fixedly connected with the upper mold 4, and the upper mold 4 is adapted to the lower mold 13.

[0031] The graphite mold auxiliary clamp of this scheme plays an important role in fixing materials, improving processing efficiency, ensuring processing quality and adapting to different processing requirements during the graphite processing. When the graphite mold is needed to press the material, the staff can first press a pair of clamping plates 21 to compress the multiple springs 22, then shorten the telescopic rod 23, and then the staff puts the lower mold 13 between the pair of clamping plates 21, and then the staff removes the force pressing on the clamping plates 21. The springs 22 and the telescopic rod 23 will reset under the action of elastic force to complete the clamping of the lower mold 13. Then the staff will start the motor 12 until the lower mold 13 rotates to the bottom of the upper mold 4, and then the staff will turn off the motor 12, and then the staff will control the electric telescopic rod 6 to extend until the upper mold 4 under the electric telescopic rod 6 coincides with the inside of the lower mold 13 to complete the pressing of the material.

[0032] See also Figure 1-4 A reserved groove 9 is provided at the top of the operating table 1, which is adapted to and connected with the placement groove 24. The reserved groove 9 runs through the operating table 1 and is connected with the outside. An annular groove 7 is provided at the top of the operating table 1, which is connected with the inside of the reserved groove 9. A plurality of rollers 8 are rotatably connected to the inside of the annular groove 7, and the plurality of rollers 8 are all in contact with the bottom end of the disc 14. A collection box 11 is provided below the reserved groove 9.

[0033] In this scheme, when the lower mold 13 is damaged due to multiple compression molding operations with the upper mold 4, the staff can start the motor 12 to interchange the positions of the two adjacent placement slots 24, so that the intact lower mold 13 is interchanged with the damaged lower mold 13, and the damaged lower mold 13 will be rotated to the top of the collection box 11. Since the elastic force of the spring 22 is less than the gravity of the lower mold 13, the lower mold 13 will fall into the collection box 11 under the action of gravity, saving the time of manual handling, thereby improving the efficiency of production using graphite molds.

[0034] In addition, the material of the lower mold 13 is graphite. Since the plurality of rollers 8 are in contact with the bottom end of the disc 14 , when the disc 14 rotates, the plurality of rollers 8 will also rotate, thereby reducing the friction of the rotating disc 14 .

[0035] Working principle: When the graphite mold is needed to press the material, the staff can first press the pair of clamping plates 21 to compress the multiple springs 22, then shorten the telescopic rod 23, and then put the lower mold 13 between the pair of clamping plates 21. Then the staff removes the force pressing the clamping plates 21, and the springs 22 and the telescopic rod 23 will reset under the action of elastic force to complete the clamping of the lower mold 13. Then the staff will start the motor 12 until the lower mold 13 rotates to the bottom of the upper mold 4, and then the staff will turn off the motor 12, and then the staff will control the electric telescopic rod 23 to release the lower mold 13. The retractable rod 6 is extended until the upper mold 4 below the electric telescopic rod 6 coincides with the interior of the lower mold 13, completing the die pressing of the material. When the lower mold 13 is damaged, the staff can start the motor 12 to interchange the positions of the two adjacent placement slots 24, so that the intact lower mold 13 is interchanged with the damaged lower mold 13, and the damaged lower mold 13 will be rotated to the top of the collection box 11. Since the elastic force of the spring 22 is less than the gravity of the lower mold 13, the lower mold 13 will fall into the collection box 11 under the action of gravity, saving the time of manual handling, thereby improving the efficiency of production using graphite molds.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
