Technical field
The present invention relates to the pressure casting methods of die cast metal technical field, especially a kind of auto parts machinery for aluminium alloy.
Background technology
Die casting is a kind of metal casting technique, its main feature is that applying high pressure to molten metal using mold cavity.Mold is logical
Often be made of higher strength alloys, this process some similar to injection molding.Most of die casting casting are all not
It is iron-containing, such as zinc, copper, aluminium, magnesium, lead, tin and terne metal and their alloy.According to the difference of die casting type, need
To use cold-chamber die casting machine or hot chamber machine.
Casting Equipment and the cost of mold are high, therefore die-casting process is generally only used in batch micro operations large-tonnage product.System
Comparatively the parts for making die casting are easier, this general only four key step of needs, unit cost increment is very low, die casting
It is particularly suitable for manufacture a large number of small and medium-sized castings, therefore die casting is that the most widely used in a variety of casting processes.With other
Foundry engieering is compared, and the surface of die casting is more smooth, possesses higher dimensional uniformity, absurd fantastic on the basis of traditional die-casting process
Several follow-on techniques have been given birth to, including have reduced the Poreless die casting technique that casting flaw excludes stomata.It is mainly used for processing zinc, it can
To reduce the direct injection technique that waste increases yield rate.Also by the essence close die-casting technique of speed of General Dynamics Corp.'s invention with
And the new-type die-casting process of semisolid pressure casting etc., in auto parts machinery production industry, the common die-casting technique of generally use carries out automobile
The production of accessory, and the die casting of common die-casting technique production at present, the especially auto parts machinery of aluminium alloy are easily deposited in tissue
Lead to bad phenomenon in stomata, while again since that there are intensity is low, mechanical performance is not high, corrosion-resistant, high temperature resistant for Al-alloy parts
The defects of poor performance.
Invention content

Include the following steps：
1), Metamorphism treatment：Raw material is melted and is warming up to 600 DEG C~745 DEG C, is added and becomes in raw material
Matter agent carries out Metamorphism treatment, stands 2 hours~2.5 hours；
2), melting：Raw material after Metamorphism treatment is warming up to 660 DEG C~820 DEG C into liquid material；
3) it, molds：Until mold parting surface has 10 millimeters~30 millimeters gaps, stopping molding；
4) oxygen, is injected into gap；
5), continue to mold, mold is closed completely；
6) liquid material, is injected into barrel；
7, after injecting liquid material, oxygen is injected into barrel；
8), die casting；
9), cooling；
10), the die casting of product is completed in die sinking.
Specifically, alterant is mixing alterant.
Specifically, the oxygen in the step 4 is the oxygen that pressure is 0.2Mpa~0.75Mpa.
Specifically, the oxygen in the step 7 is the oxygen that pressure is 0.03Mpa~0.1Mpa.
Specifically, the mixing alterant is Sr by mass fraction：0.06%, carbon hexachloride, manganese chloride composition, enhance aluminium
The tensile strength of alloy.
Advantageous effect：Compared with prior art the advantage of the invention is that：As a result of this aluminium alloy, manufactured product
Tensile strength, modifying-refining tissue, heat resistance, elongation percentage be improved；Inside die-casting part stomata fraction defective is greatly decreased, production
Product qualification rate has been increased to 95% or more, adds mixing alterant and makes the practicability for improving material after Metamorphism treatment
Energy.
