Abstract

The invention discloses a die-casting method of semisolid die-casting aluminum alloy. The die-casting method of the semisolid die-casting aluminum alloy specifically comprises the following steps of S1 conducting die assembly, wherein a movable die body and a fixed die body of a die-casting die are connected; S2 selecting materials, wherein 50-55 parts of aluminum, 10-15 parts of magnesium, 10-15 parts of copper, 5-10 parts of silicone, 5-10 parts of zinc and 1-5 parts of iron are selected and mixed to prepare the aluminum alloy; S3 melting the materials, wherein the prepared mixed metal objects are continuously heated until the mixed metal objects are slowly molten into metal liquid; S4 preparing slurry, wherein the prepared molten metal prepared in the S3 is guided into a slurry preparing chamber, and semisolid slurry is prepared. Semisolid liquid type die casting is adopted, the prepared mixed metal objects are continuously heated in a heating melting furnace in the vacuum environment until the mixed metal objects are slowly molten into metal liquid, the temperature of the heating melting furnace is 1500-1700 DEG C, and the prepared molten metal liquid is guided into the slurry preparing chamber. By the adoption of the die casting method of the aluminum alloy, the elongation of the aluminum alloy is higher than that of a control group, the mold filling temperature is low, and the service life of the aluminum alloy is prolonged.

Description

Technical field [0001] The invention relates to the technical field of alloy die-casting molding, in particular to a die-casting method of semi-solid die-cast aluminum alloy. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the weldability of aluminum alloy is also intensified. The density of aluminum alloy is low, but the strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is second only to steel. Some aluminum alloys can be heat treated to obtain good mec...
