Discharge type aluminium die casting
Technical field
The utility model relates to a kind of aluminium die casting, relates in particular to a kind of discharge type aluminium die casting, belongs to casting technology field.
Background technology
In modern casting technology field, for die casting goes out better product, begin to develop to directions such as comprising perfusion, alloy molten from common simple die casting, utilize the mould design, can design mode such as filling cavity on traditional die casting basis and carry out the die casting of labyrinth.The application of die-casting technique is very extensive, and particularly the die casting manufacturing process of aluminium or aluminium alloy has been subjected to welcome because the metallic character of aluminium or aluminium alloy is fit to the die casting manufacturing in industrial development.Usually, the die casting manufacturing process of aluminium or aluminium alloy may further comprise the steps:
One, prepares mould, comprise the preheating of Mould design, mould, the installation of mould etc.;
Two, fusion operation or the melting process of metal charge comprise the fusing of metal such as aluminum or aluminum alloy, by the mode of heating, make metal reach the state of fusing or fritting;
Three, die casting, namely molten metal is poured in the mould, and the matched moulds up and down by mould is with metal stamping formed, and general stamping pressure is between 40 tons to 100 tons;
Four, cooling is about to stamping forming metal casting and takes out from mould, and carries out cooling processing, reaches indoor temperature and gets final product;
Five, cleaning polishing is namely carried out polishing grinding to the metal casting behind the cooling forming and is handled, and making smooth surface becomes finished product.
This shows that in the process of die casting, mould is extremely important, other step all is the common technology that belongs to this area, and Mould design be related to the metal casting of die casting can be rational in infrastructure, whether the product that stamps out adheres to specification.And mould of the prior art all is traditional design, and is relatively backward in function aspects, is difficult to satisfy the product design requirement of labyrinth.
The utility model content
In order to overcome the deficiencies in the prior art, resolve prior art problems, remedy the existing deficiency of existing product in the market.
The utility model provides a kind of discharge type aluminium die casting, comprise the cope match-plate pattern of upper end, the moulded board of centre and the lower bolster of lower end, in the middle of moulded board, offer a die cavity, be provided with die cavity in the middle of the die cavity, outer setting at die cavity has cast gate, in cope match-plate pattern and moulded board, offer perfusion channel, the upper end open of perfusion channel is arranged on the surface of cope match-plate pattern, die cavity in the lower ending opening of perfusion channel and the die cavity is communicated with, top at described die cavity arranges the exhaust passage, and the gas outlet of described exhaust passage links to each other with vavuum pump.
Preferably, side one end of above-mentioned cope match-plate pattern is provided with controller, and the other end is provided with driver.
Preferably, be provided with elastic support between above-mentioned die cavity and the lower bolster.
Preferably, above-mentioned die cavity is by being bolted on the lower bolster.
Preferably, the side of above-mentioned cope match-plate pattern is provided with blast pipe, and the top of blast pipe is provided with air bleeding valve, and the other end of blast pipe is connected with safety lock.
Preferably, the upper end of above-mentioned lower bolster is provided with heat emission fan.
Preferably, be provided with supporting base between above-mentioned moulded board and the lower bolster.
The discharge type aluminium die casting that the utility model provides is compared with traditional compression tool, the discharge type aluminium die casting that the utility model provides is by arranging the exhaust passage, air unnecessary in the die cavity is discharged, thereby prevent that bubble from appearring in product, improved the quality of product.
