▎ 摘　　要

NOVELTY - The mold has an interference sleeve (1) made of medium-carbon steel, where cross-section of the interference sleeve is formed as a round shaped structure. The interference sleeve is provided with cutting edges (2). An interference fit part is connected with the interference sleeve. A surface of the interference sleeve is coated with a graphene coating layer (3). The cutting edges are made of steel. USE - Detachable zigzag anti-corrosive edge cutting mold. ADVANTAGE - The mold reduces production cost and adopts the interference sleeve that is coated with the graphene coating layer so as to improve corrosion resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a detachable zigzag anti-corrosive edge cutting mold. Interference sleeve (1) Cutting edges (2) Graphene coating layer (3)
