Abstract
The present invention relates to a kind of arenaceous shell casting method for being used to produce the part used in automobile and aviation field, wherein, metal or alloy is poured into shell to produce part；The shell is forced and rapidly cooled down；And the part is removed.
Description
The present invention relates to the alloy of casting technology field, particularly aluminium, magnesium, copper or other similar materials.
More particularly, it relates to a kind of arenaceous shell casting method, for producing the portion used in automobile and aviation field
Part.
Arenaceous shell casting method be well known to a person skilled in the art.
Including the use of the sand for being pre-coated with thermosetting resin, it is contacted with being heated to the mould plate of about 200 DEG C of temperature for it,
Hardened on several millimeters of layer, form shell.Each shell corresponds to half module, is then polymerized, then glued.
In various arenaceous shell casting methods, it can mention and (polishing, hot tank, ice chest, warm up case, no cabinet etc.).
The casting method has some advantages, wherein the possibility for producing extremely complex geometry is may be mentioned that,
And difference in functionality is integrated into the possibility on considered part, such as the exhaust manifold in the cylinder head of motor vehicles.
It should be noted that other advantages, such as the weight saving of the part obtained.In addition, this method needs Low investment, and can
Reduce the quantity of process operation.
On the contrary, considering low-down freezing rate, the part obtained by the arenaceous shell casting method has answers some
With not always gratifying mechanical property in field.
Therefore, when these parts do not need good mechanical property, shell cast method will be particularly suitable for manufacturing
The part of complicated geometry.
It will be apparent, however, that not only the geometry of part becomes to become increasingly complex, and the machinery of these parts
Characteristic must reach high level, to meet code requirement.
From the point of view of prior art and such case, it is therefore important that arenaceous shell casting method can be improved, that can obtain
The part with extremely complex geometry with good mechanical properties.
In order to overcome this problem, according to the present invention, arenaceous shell casting method is had been designed that, according to this method,
In one embodiment：
- metal or alloy is poured into produce part in shell,
- the shell is forced and rapidly cooled down,
- realize the part decoring operation.
This method has in automobile and aviation field particularly advantageously to be applied, and for producing extremely complex part, is needed
Mechanical property that will be very good.Arenaceous shell in known manner according to be suitable for the part to be obtained property (hot tank, ice chest,
Warm case, 3D printing etc.) method manufacture.According to the characteristic for the part to be obtained, the thickness of shell is also suitable for quiet to reach metal
Optimal compromise between Voltage force and interface resistance.
As noted, after casting metal or alloy, such as by quenching, by comprising the metal or the alloy still
Arenaceous shell cooling in liquid or solidifying phase.In known manner, the quenching can pass through water, oil, air or any other
Allow the means of this cooling.Quick and compulsory cooling means that housing is quenched when alloy is still liquid.As non-
Restricted example, hardening heat are less than 100 DEG C.
Both operations of cast and cooling have two-fold advantage, the advantage, on the one hand, by establishing heat during quenching
Gradient makes it possible to the orientation of solidification front, and on the other hand, increases freezing rate, and the therefore part of increase gained
Mechanical property.
Then, the part simply needs to be subjected to conventional decoring operation, and the decoring can be chemical, hot or mechanical
's.
According to a further embodiment of the method according to the invention, it is no longer most that metal or alloy, which is poured into shell to produce,
Back part, but preform.Obviously, therefore the profile of shell is suitable.Then, as previously noted, shell to force and
Rapid mode is cooled, and realizes the operation of the decoring of preform.
According to the present invention casting method embodiment in, as be based on brand COBAPRESS known to method, make it is pre- into
Shape base is subjected to the punching press and and forging operation of combination.Teaching of the COBAPRESS methods based on such as patent EP 0119365.
According to the characteristic of the present invention, the arenaceous shell casting method makes it possible to obtain than the arenaceous shell casting side according to prior art
The much better mechanical property of mechanical property that method obtains, such as the following test result institute carried out with the metal or alloy of same type
Show.
According to the shell moulded casting method of prior art：
SDAS：60-70μm
Rp0.2=200-220MPa
Rm=240-260MPa
A%=1-2%
According to the shell moulded casting method of the present invention：
SDAS：30-35μm
Rp0.2=220-260MPa
Rm=290-310MPa
A%=6-8%
Formula, wherein, SDAS corresponds to interdendritic gap, and Rp corresponds to elastic limit, and Rm corresponds to mechanical resistance, with
And A% corresponds to elongation.
Can be seen that this method from the characteristic of the method according to the invention will be poured into arenaceous shell so that can be had
There is the advantages of part of complex geometric shapes, decline with weight, process operation is reduced, while needs small investment, and is had
Superperformance is combined, as shown in above-mentioned contrast test.It should also be noted that the application of COBAPRESS methods makes it possible to greatly
Amount reduces porosity and skin effect.
