S5, the core removed in foundry goods water channel and coating；
The processing of S6, sand export and welding, and casting of appearance of cast is cleared up, polishes；
S7, foundry goods is carried out heat treatment；
S8, foundry goods is carried out ball blast；
In a preferred embodiment of the invention, in step S1, melting is to use continuous way natural gas fusing stove, by corresponding material
Aluminium ingot is molten into aluminum liquid, then carry out going bad, refine, go out aluminum temperature and control735-745℃In the range of.Refining agent can be purity
It is the argon of 99.99%, and Effictive nuisancelless slag-cleaning agent；Alterant used can be al-sr alloy.
Step S2 method particularly includes: mold temperature is baked to 280-320 DEG C, cast gate temperature be baked to more than 350 DEG C, and
Uniformly Bian Mo and on loose core spraying releasing agent, then carry out joining core in core is placed into mould, last matched moulds is poured into a mould.Coating is
Send 39# and 34# of Rake company with the use of.
In step S3, cast is that at the aluminum liquid of 685-700 DEG C temperature sequentially passed through following steps:
S31, under the pressure of 400mbar, keep 15～17s；
S32, under the pressure of 400mbar, keep 1～2s；
S33, under the pressure of 750mbar, keep 6～8s；
S34, under the pressure of 750mbar, pressurize 400～900s.
In step S4, horizontal saw mill and CUT is used to remove dead head.
In step S5, sand removal, is by nonheat-treated foundry goods, uses dither shakeout by sand cores of castings and core table
The shatter removing of coating materials.
In step S6, use Boring machine processing sand export, use argon arc welding welding.
In step S7, heat treatment is that solution treatment adds the process of complete artificial aging.
In step S8, use the stainless shot of φ 0.6mm that cast outer surface is carried out Shot Blasting.
In another preferred embodiment of the invention, the argon arc welding after bore hole of the foundry goods after step S5, and right
Casting of appearance of cast is polished, and is then passed through heat treatment, and the foundry goods after heat treatment carries out stainless steel throwing pill process, by the electricity after ball blast
Casing foundry goods is put in storage.
By the technical scheme given above it is understood that casting die of the present invention, due to described foundry goods thickness large part
Outer surface arranges water cooling plant 7, and silk hole carries out bottom outlet precasting, accelerates the cooling of this position, it is to avoid shrinkage cavity defect.Inner chamber reduces machine
Tool allowance, so that machined surface is positioned in foundry goods compacted zone, it is to avoid what embedded SMA actuators reduction of area hole caused suppresses gas leakage.On
End arranges insulated feeder 17, strengthen the feeding capacity to whole foundry goods, it is to avoid shrinkage cavity and the feeding deficiency on foundry goods top cause
The shrinkage cavity of foundry goods stage casing.Under the conditions of the casting technique that the present invention is advocated, the qualification rate of described water cooling motor housing is made to be carried by 50%
Height, to more than 96%, significantly reduces pressure testing leakage problem, it is achieved thereby that the purpose of the present invention.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
The change obtained without creative work or replacement, all should contain within protection scope of the present invention.Therefore, the present invention
Protection domain should be as the criterion with the protection domain that claims are limited.
