[0002] Molds are widely used basic process equipment in industrial production, and the mold industry is the basic industry of the national economy. In modern industrial production, product parts are widely used in stamping, forging, die casting, extrusion, plastic injection or other forming methods, which are matched with forming molds to make the blanks formed into parts that meet the product requirements. Various tools and products used in our daily production and life, from the base and body shell of machine tools to the embryo head screws, buttons and the shells of various household appliances, are closely related to molds. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. In recent years, the mold industry has developed rapidly, and graphite materials, new processes and increasing mold factories have continuously impacted the mold market. Graphite has gradually become the preferred material for mold production with its good physical and chemical properties.

[0003] According to the needs of the existing market, graphite molds are diverse, and there are more and more special-shaped graphite molds. It is difficult to have suitable tools for grinding. For example, a mold with multiple arc-shaped grooves equidistantly opened on the upper surface of the graphite mold can be used to make structures such as tool heads and cylinders after the mold is closed. Faced with so many arc-shaped grooves, the efficiency of manual grinding is greatly reduced, and the burrs inside the grooves are difficult to be fully processed.

[0028] Working principle: When in use, the graphite mold body 27 is placed on the upper surface of the ornament table 9. After the two clamping rods 10 are placed in the graphite mold body 27, the spring 29 at the slide bar 28 is squeezed. The two clamping rods 10 press on both sides of the graphite mold body 27 to ensure that the graphite mold body 27 can be more stable during the later grinding. Then the worker adjusts the corresponding slide 21 so that the corresponding grinding roller 24 corresponds to the arc groove on the surface of the graphite mold body 27. Then, under the lifting of the third hydraulic cylinder 15, the ornament table 9 rises, and the arc groove of the graphite mold body 27 contacts the outside of the grinding roller 24. After completing the adjustment of the slide 21 in sequence, the first hydraulic cylinder 6 drives The stopper 7 and the clamping rod 5 move downward, so that the clamping rod 5 is pressed against the clamping slot 25 on the upper surface of the slide 21, thereby limiting each group of slides 21. At this time, the second hydraulic cylinder 12 drives the stopper 31 to push the gear rod 30 to move back and forth. The gear rod 30 drives the gear 22 outside the fixed cylinder 23 to rotate, and the fixed cylinder 23 can drive the grinding roller 24 to rotate inside the corresponding arc-shaped groove. The outer surface of the grinding roller 24 contacts the burrs on the inner surface of the arc-shaped groove to fully grind the graphite mold body 27. During the grinding process, the drip tube 20 inside the liquid storage tube 8 can drip the polishing liquid filled inside onto the grinding roller 24, which increases the gloss during grinding during the grinding process of the grinding roller 24.
