Embodiment 1

[0027] An improved die casting molding method, comprising the following steps:

[0028] S1. Melting: Put the aluminum alloy material into the heating furnace and continue heating to 730°C to obtain a melt; then use compressed argon or compressed nitrogen as a carrier to evenly add strengthening particles to the melt, remove the slag and let it stand to obtain the first a melt.

[0029] The reinforcing particles are nanoscale TiC or nanoscale SiC particles, and the added amount is 0.5% of the weight of the melt. While adding strengthening particles, the melt is ultrasonically vibrated to improve uniformity.

[0030] The raw materials of the aluminum alloy in this embodiment are: Mg: 0.3%, Si: 0.3%, Fe: 0.2%, Cu: 0.45-0.6%, Mn: 0.05%, Cr: 0.04%, Zn: 0.2%, Ti: 0.03%, Al: balance.

[0031] S2. Stirring: Stir the first melt by means of electromagnetic stirring, and gradually lower the temperature to obtain an ingot.

[0032] S3. Remelting material: cutting the cast ingot into b...

[0039] An improved die-casting forming method is basically the same as in Example 1, except that the raw materials of the aluminum alloy and the specific parameters of the process are different, as follows:

[0040] S1. Melting: Put the aluminum alloy material into the heating furnace and heat it continuously to 760°C to obtain a melt; then use compressed argon or compressed nitrogen as a carrier to evenly add strengthening particles to the melt, remove the slag and let it stand to obtain the first a melt.

[0041] The reinforcing particles are nano-sized TiC particles, and the added amount is 2% of the weight of the melt. While adding strengthening particles, the melt is ultrasonically vibrated to improve uniformity.

[0042] The raw materials of the aluminum alloy in this embodiment are: Mg: 0.5%, Si: 0.6%, Fe: 0.5%, Cu: 0.5%, Mn: 0.08%, Cr: 0.2%, Zn: 0.4%, Ti: 0.2%, Al: balance.

[0043] S2. Stirring: Stir the first melt by means of electromagnetic stirring, and graduall...

Embodiment 3

[0051] An improved die-casting forming method is basically the same as in Example 1, except that the raw materials of the aluminum alloy and the specific parameters of the process are different, as follows:

[0052] S1. Melting: Put the aluminum alloy material into the heating furnace and continue heating to 820°C to obtain a melt; then use compressed argon or compressed nitrogen as a carrier to evenly add strengthening particles to the melt, remove the slag and let it stand to obtain the first a melt.

[0053] The reinforcing particles are nano-scale SiC particles, and the added amount is 3% of the weight of the melt. While adding strengthening particles, the melt is ultrasonically vibrated to improve uniformity.

Abstract

The invention provides an improved method for forming die castings, which includes the following steps: S1. Smelting: put the aluminum alloy material into a heating furnace and continue heating to obtain a melt; then use compressed argon or compressed nitrogen as a carrier to inject Add reinforced particles evenly in the medium, remove slag and let stand to obtain the first melt; S2. Stirring: stir the first melt by electromagnetic stirring to obtain ingots; S3. Remelt material: cut the ingots into blanks, re Heating to obtain the second melt; S4, mold treatment: preheating the mold and keeping it warm for 1 hour; S5, die-casting: transferring the second melt to a low-pressure casting machine holding furnace for heat preservation; then under low pressure conditions, the second melt Die-casting into the cavity of the mold to obtain a die-casting; S6, heat treatment: the obtained die-casting is subjected to a heat treatment process of solution treatment and incomplete artificial aging. The aluminum alloy product obtained by the process of the invention has compact structure, good comprehensive mechanical properties and physical and chemical properties, high material utilization rate and low cost.

Description

technical field [0001] The invention relates to the technical field of alloy die casting, in particular to an improved die casting forming method. Background technique [0002] Aluminum and its alloys are favored because of their excellent mechanical properties, corrosion resistance, and formability. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . In recent years, aluminum alloys have been used more and more in industries such as automobiles, ships, and home appliances. With the upgrading of product manufacturing and the improvement of end product performance requirements, all walks of life have put forward higher requirements for the performance of aluminum alloys. Not only the casting s...
