The invention discloses a strong wear resistance maintenance method for an aluminum alloy piston casting mold, and relates to the technical field of mold machining. The method comprises the following steps of, cleaning a mold, shaping the worn part of the mold by using soft wax, establishing 3D modeling of the worn part of the mold, machining a maintenance piece made of a tungsten filament material, combining the maintenance piece with the worn part of the mold, machining the maintenance piece and the mold by using maintenance equipment, and grinding and trimming the connecting part of the maintenance piece and the mold. Before the mold is repaired, the soft wax is heated and covers the worn part of the mold for shaping, so that the worn shape of the mold can be determined, and the tungsten filament is machined into the maintenance part according to the 3D model; and the melting point of the maintenance part can be increased by using the tungsten filament, so that the wear resistance of the repaired mold can be improved, the maintenance piece can be in full contact with the worn part of the mold, and the repairing quality can be improved.
Description
technical field [0001] The invention relates to the technical field of mold processing, in particular to a strong wear resistance maintenance method for an aluminum alloy piston casting mold. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts. Different molds are composed of different parts. During the production of aluminum alloy pistons, the mold is washed by high-temperature aluminum water. The surface of the mold is gradually worn out, which affects the size of the product. In order to ensure the normal use of the mold, the mold needs to be maintained and repaired regularly. The conventional mold repair uses welding wire to repair the worn part of the shape. [0003] After retrieval, the...
