Description

Technical Field

[0001] The utility model relates to the field of graphite processing, and more specifically, to a mixing component and a graphite mold processing device. Background Art

[0002] Graphite is a mineral that is generally produced in metamorphic rocks. It is formed by regional metamorphism or magma intrusion of coal or carbonaceous rocks. It is an important raw material in modern industry and manufacturing. Graphite has gradually become the preferred material for mold making due to its good physical and chemical properties.

[0003] When processing graphite molds, first select high-quality graphite powder and mix it with binders in a specific ratio to ensure uniform mixing. Then fill the mixed graphite material into a pre-designed mold and apply high pressure to it through hydraulic means to make the material flow and compact under pressure, filling all the gaps in the mold and forming a tight structure. Then open the mold to take out the formed graphite mold product.

[0004] In the actual use of the existing technology, when processing a graphite mold, an operator is required to fill the mixed graphite material into the mold for compaction and molding. Since the manual filling and loading process is relatively slow and requires a lot of time and energy, the production and processing efficiency is low. Therefore, a mixing assembly and a graphite mold processing device are proposed. Utility Model Content

The lower mold filled with graphite powder will be moved to the bottom of the upper mold and driven by the hydraulic rod to move the upper mold downward for pressing and molding. The lower mold that has been pressed and molded inside will be moved to the bottom of the push block and pushed downward by the electric telescopic rod to push the molded graphite mold in the lower mold to fall through the drop hole, realizing fully automated operation and the entire process of automatic mixing, conveying, loading, pressing and unloading of graphite powder, saving the energy and time consumed by manual operation to improve production efficiency.

[0036] Furthermore, the driving motor 302 is started to drive the cross 301 to rotate 90 degrees to drive the lower mold 303 filled with graphite powder to move its position. By rotating the cross 301, the other lower mold 303 not filled with graphite powder can be rotated and moved to the bottom of the conveying pipe 208 for continuous loading. At the same time, the lower mold 303 filled with graphite powder will be moved to the bottom of the upper mold 313. At this time, the hydraulic rod 310 is started to drive the upper mold 313 to move downward into the lower mold 303 to press the graphite powder. Then the driving motor 302 is controlled to drive the lower mold 303 with the internal graphite powder pressed to rotate 90 degrees so that it is located under the pusher block 403. At this time, the electric telescopic rod 402 is started to drive the pusher block 403 to move downward to push the graphite mold pressed in the lower mold 303. The tool falls through the blanking hole 101, which is convenient for the operator to collect it uniformly and realize fully automated operation. There is no need for manual loading and unloading, so as to improve production efficiency. When it is necessary to replace the upper mold 313 and the lower mold 303 to process molds of other shapes, the operator can manually move the movable plate 306 upward to drive the telescopic rod 307 and spring 1 308 to extend upward.

[0037] Working principle: During the use of the device, the operator places the operating table 1 in the designated place for mixing the graphite mold, then rotates and opens the barrel cover 203 to put the graphite powder and the binder into the mixing barrel 202 in a specific proportion, and starts the motor 204 to drive the stirring rod 205 to rotate to fully mix the graphite powder and the binder. When the stirring rod 205 rotates, it drives the scraper 206 to scrape the inner wall of the mixing barrel 202 to prevent some graphite powder from adhering to the inner wall of the mixing barrel 202 and not being stirred, resulting in uneven mixing. At the same time, it avoids omissions during material discharge, resulting in waste of resources, and then opens the electric valve 207. At this time, the mixture is well mixed. The graphite powder automatically falls into the conveying pipe 208, and the conveying motor 209 is controlled to drive the spiral conveying pipe 210 to rotate to automatically convey the mixed graphite powder to the lower mold 303, thereby realizing automatic mixing and conveying of the graphite powder, saving the energy and time consumed by human operation, and improving the efficiency of processing and production. Then, the driving motor 302 is started to drive the cross 301 to rotate 90 degrees to drive the lower mold 303 filled with graphite powder to move the position. By rotating the cross 301, the other lower mold 303 not filled with graphite powder can be rotated and moved to the bottom of the conveying pipe 208 for continuous loading. At the same time, the lower mold 303 filled with graphite powder will be moved to the upper mold 303. The upper mold 313 is under the mold 313, and the hydraulic rod 310 is started to drive the upper mold 313 to move downward into the lower mold 303 to press the graphite powder into shape. Then the driving motor 302 is controlled to drive the lower mold 303 with the internal graphite powder pressed to rotate 90 degrees so that it is located under the pusher block 403. At this time, the electric telescopic rod 402 is started to drive the pusher block 403 to move downward, pushing the graphite mold pressed in the lower mold 303 to fall through the blanking hole 101, which is convenient for the operator to collect uniformly and realize fully automated operation without manual loading and unloading, so as to improve production efficiency. When leading molds of other shapes, the operator can manually move the movable plate 306 upward to drive the telescopic rod 307 and spring 1 308 to extend upward. When the movable plate 306 moves upward to drive the plug block 305 to leave the inner cavity of the connecting block 304, the lower mold 303 loses its fixed limit and can be replaced. The plug rod 315 is pulled outward to drive spring 2 316 to extend outward. When the plug rod 315 moves outward to leave the inner cavity of the connecting rod 312, the lower mold 303 loses its fixed limit and can be replaced.
