Description

Technical Field

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

[0002] In the field of graphite electrode manufacturing, due to the high hardness of graphite material itself, and the fact that it is subjected to high pressure and significant friction with the mold cavity surface during the molding process, the cavity surface is prone to wear. After the mold wears down, the dimensional accuracy of the cavity will decrease, which directly affects the molding accuracy of the graphite electrode and thus leads to a reduction in product quality.

[0003] Meanwhile, due to wear on the surface of the mold cavity, the worn parts need to be repaired or replaced. Repair may involve multiple processes such as grinding, welding, and reprocessing, which not only significantly increases production costs but also significantly reduces production efficiency. When replacing traditional molds, the mold needs to be removed from the equipment first. The disassembly process requires the use of various tools and careful operation to avoid damaging the equipment and mold. After disassembly, the installation of the new mold also requires precise alignment, adjustment, and fixation to ensure the accuracy of mold installation. The entire replacement process is very cumbersome and consumes a lot of production time. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a graphite electrode processing and forming mold, which effectively solves the problem of inconvenient mold maintenance and replacement.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a graphite electrode processing and forming mold, including a pressure plate and a worktable located below it, an upper mold is detachably installed at the bottom of the pressure plate, a lower mold corresponding to the upper mold is provided on the worktable, the lower mold is a hollow cavity structure placed in the installation space on the worktable, a limit mounting plate is fixed to the outer side wall of both the upper mold and the lower mold, and the same limit detachable mechanism connected to the limit mounting plate is provided on both the pressure plate and the worktable;

[0006] The detachable limiting mechanism includes a pressure groove, which is embedded in the limiting mounting plate. A limiting pressure plate is pressed into the pressure groove. Multiple sets of the lower mold and upper mold are symmetrically arranged. The limiting pressure plate is pressed onto the pressure grooves on multiple limiting mounting plates simultaneously.

[0007] Preferably, the detachable limiting mechanism further includes a limiting groove, which is provided on the worktable. The limiting pressure plate is horizontally slidably disposed in the limiting groove. A connecting plate is fixed to the bottom of the limiting pressure plate. External plates are fixed to both sides of the worktable. A bidirectional lead screw that is threadedly connected to the connecting plate is rotatably provided on the external plate. End blocks are fixed at both ends of the bidirectional lead screw.

[0008] Preferably, the longitudinal section of the pressure groove is a concave shape with an opening in the middle, and the shape of the limiting pressure plate 1 is adapted to the shape of the pressure groove.

[0009] Preferably, the limiting mounting plate on the pressure plate has a mating groove on the side away from the pressure groove, and a matching mating block is fixed on the pressure plate, the mating block having an L-shaped longitudinal section.

[0010] Preferably, a bottom support plate is sealed and fixed at the bottom of the worktable below the lower mold, and a cylinder installed at the bottom of the bottom support plate is fixedly connected to the bottom of the worktable, with the movable end of the cylinder fixed on the bottom surface of the bottom support plate.

[0011] Preferably, the bottom support plate and the inner cavity of the lower mold have the same shape and size.

[0012] The beneficial effects of the above-mentioned structure are as follows: By setting the same limit detachable mechanism on the pressure plate and the worktable, and using the bidirectional screw to drive the limit pressure plates on both sides to press into the pressure groove of the limit mounting plate, multiple sets of lower molds and upper molds can be fixed or disassembled at the same time, which greatly shortens the mold replacement time, facilitates maintenance and replacement, and significantly improves production efficiency.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, the present invention proposes a graphite electrode processing and forming mold, including a pressure plate 1 and a worktable 2 located below it. An upper mold 3 is detachably installed at the bottom of the pressure plate 1. A lower mold 4 corresponding to the upper mold 3 is provided on the worktable 2. The lower mold 4 is a hollow cavity structure placed in the installation space on the worktable 2. Limiting mounting plates 5 are fixed to the outer side walls of both the upper mold 3 and the lower mold 4. The pressure plate 1 and the worktable 2 are both provided with the same limiting and detachable mechanism 6 connected to the limiting mounting plate 5.

[0022] The detachable limiting mechanism 6 includes a pressing groove 7, which is embedded in the limiting mounting plate 5. A limiting pressure plate 8 is pressed into the pressing groove 7. The longitudinal section of the pressing groove 7 is a concave shape with an opening in the middle. The limiting pressure plate 8 and the pressing groove 7 are matched in shape. Multiple sets are symmetrically arranged on the lower mold 4 and the upper mold 3. The limiting pressure plate 8 is pressed into the pressing groove 7 on multiple limiting mounting plates 5 at the same time.

[0023] like Figure 2 , 3 As shown, the detachable limiting mechanism 6 also includes a limiting groove 9, which is located on the worktable 2. The limiting pressure plate 8 is horizontally slidably located in the limiting groove 9. A connecting plate 10 is fixed to the bottom of the limiting pressure plate 8. External plates 11 are fixed to both sides of the worktable 2. A bidirectional screw 12 that is threadedly connected to the connecting plate 10 is rotatably provided on the external plate 11. End blocks 13 are fixed to both ends of the bidirectional screw 12. Rotating the end blocks 13 drives the bidirectional screw 12 to rotate. The bidirectional screw 12 drives the connecting plate 10 and the limiting pressure plate 8 to move inward, pressing the limiting pressure plate 8 into the pressure groove 7 and fixing the position of the limiting mounting plate 5. This locks multiple sets of upper molds 3 and lower molds 4 between the pressure plate 1 and the worktable 2.

[0024] like Figure 5 As shown, a mating groove 14 is provided on the side of the limiting mounting plate 5 on the pressure plate 1 away from the pressure groove 7. A matching mating block 15 is fixed on the pressure plate 1. The longitudinal section of the mating block 15 is L-shaped, which initially limits the positioning of the limiting mounting plate 5.

[0025] like Figure 1 , 3 As shown, a bottom support plate 16 is sealed and fixed at the bottom of the worktable 2 below the lower mold 4. The bottom support plate 16 and the lower mold 4 have the same shape and size. A cylinder 17 is fixedly connected to the bottom of the bottom support plate 16 and installed at the bottom of the worktable 2. The movable end of the cylinder 17 is fixed on the bottom surface of the bottom support plate 16. The cylinder 17 drives the bottom support plate 16 to push out the graphite electrode.

[0026] In practical use, first place the lower mold 4 on the mounting hole on the worktable 2, so that the limiting mounting plate 5 of the lower mold 4 is placed on the worktable 2 and the positions of the pressure groove 7 and the limiting pressure plate 8 are aligned. At the same time, align the mating groove 14 on the limiting mounting plate 5 of the upper mold 3 with the mating block 15, push it towards the mating block 15, and place the mating block 15 into the mating groove 14. Then, install the upper mold 3 on the pressure plate 1.

[0027] Rotating end block 13 drives bidirectional lead screw 12 to rotate, bidirectional lead screw 12 drives connecting plate 10 and limiting pressure plate 8 to move inward, pressing the limiting pressure plate 8 into the pressure groove 7. As the limiting pressure plate 8 is pressed, the upper mold 3 and pressure plate 1, and the lower mold 4 and worktable 2 are firmly fixed, thereby locking multiple sets of upper mold 3 and lower mold 4 onto pressure plate 1 and worktable 2 at the same time, completing the mold installation process.

[0028] The graphite material is placed into the cavity of the installed lower mold 4. The bottom of the graphite material is supported by the bottom support plate 16. Pressure is applied by the pressure plate 1 to form the graphite material in the cavity of the lower mold 4. During the forming process, after one graphite electrode is formed, the cylinder 17 drives the bottom support plate 16 to push out the formed graphite electrode.

[0029] The bidirectional lead screw 12 rotates in the opposite direction, causing the limit pressure plate 8 to release the clamping force on the limit mounting plate 5. At this time, the upper mold 3 can be easily removed from the pressure plate 1, and the lower mold 4 can be easily removed from the worktable 2, completing the disassembly of the mold and facilitating disassembly and maintenance.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
