Definitions
- the present invention relates to a new method and device for manufacturing aluminum parts, or of cast aluminum alloy.
- One of the known methods consists in manufacturing them by stamping, or by forging, which has the advantage of giving them a metallographic structure at heart corresponding to high mechanical performance.
- Another known method consists in manufacturing the parts by molding with lost wax, in particular when it is desired to produce parts having precise geometric dimensions, and a surface finish of an excellent finish.
- the object of the present invention is to avoid these drawbacks, by using an improved casting process, making it possible to manufacture pieces of aluminum or light alloy having better performances than those obtained by a conventional process.
- the method according to the invention consists in casting aluminum or an aluminum alloy, in a mold, in order to obtain, at the end of solidification, a sufficiently rigid metal part, and it is characterized in that immediately after the pouring, the still hot part is removed from the mold, and it is placed between the two shells of the matrix defining an imprint of dimensions slightly smaller than those of the mold, the two shells of the matrix then being strongly pressed against each other, to exert on the casting, on either side of which it is located, a combined effect of pressing to the core, and of surface dressing.
- the temperature at the heart of the molded part is still between 400 ° and 500 ° degrees centigrade at the time of pressing between the shells of the matrix.
- the two shells of the matrix are mounted in a press, for example at eccentric, which subjects the part to a percussion or to a pressing or a pressing between the two shells of the matrix.
- the molding of the place is carried out by tilting at ninety degrees, or one hundred and eighty degrees, in a shell, which makes it possible to obtain a quiet filling, without oxidation, no bubbling.
- An aluminum alloy is treated with copper, of the type known under the trade name AU5GT Y34.
- a silicon aluminum alloy is used, of the type known under the trade name A3ZG 06 Y33.
