Description
Technical field
The present invention relates to a kind of low-pressure casting process, in particular to a kind of low-pressure casting process of aluminium alloy wheel hub of vehicle.
Background technique
Casting aluminium alloy wheel hub technique generally comprises: feeding, melts, refining, sampling, coming out of the stove, refining degasification and go bad, take
The techniques such as sample, metaideophone, parameter adjustment, die casting, inspection.And the parameter adjustment after metaideophone is extremely important in entire casting process,
Generally in the industry by liquid aluminium alloy temperature control in the holding furnace of metaideophone within the scope of 690 DEG C -710 DEG C, whole flow process includes rising
Liquid fills type, pressurization, pressure maintaining, natural cooling etc. and the adjustment and control of technological parameter." rising liquid " refers to liquid aluminium alloy in air pressure
Under the action of from liquid level enter the process that stalk rises to cast gate；" filling type ": refer to the pressure for keeping certain in holding furnace
In the case where enter liquid aluminium alloy in mold cavity by cast gate position with stable flow velocity and complete to fill the entire of type
Process；" pressurization " refers to after liquid aluminium alloy is full of type chamber, is further continued for increasing to certain pressure, mainly makes casting one
Effective feeding can also be carried out while crystallized and solidified under conditions of constant-pressure." pressure maintaining " refers to heat preservation furnace pressure
Pressure when castings crystallization is increased to, needs to continue to keep such pressure until casting solidification, crystallize rear to a certain extent
It can release." natural cooling " is after pressure maintaining terminates, the liquid aluminium alloy of stalk falls back to holding furnace, and casting is in mold closed form
The time that can be demoulded is naturally cooled under state.Current casting low-voltage device common in the industry is as shown in Figure 1,11 to keep the temperature in figure
Furnace, 12 be connecting flange, and 13 be stalk fixing sleeve, and 14 be low pressure board bottom plate, and 15 be vacuum cup, and 16 be sprue bush, and 17 are
Mold, 18 be stalk, and stalk bottom end extends in holding furnace and is located under liquid aluminium alloy liquid level, and heat preservation furnace upper end is upward
Extend the vacuum cup for stretching out holding furnace and extending to mold, keeps the temperature and be connected with connecting flange on furnace top surface, stalk is in connection method
Outer wall between blue and lower mould is cased with stalk fixing sleeve, and this structure has the following deficiencies: due to holding furnace and mold
The flange of connection and the length of stalk fixing sleeve are longer, and the thermal insulation material thickness low LCL of flange outer wall leads to liquid aluminium alloy
Temperature is scattered and disappeared excessively, and the heat loss after stalk enters mold cavity of the liquid aluminium alloy in holding furnace is larger, heat preservation
Liquid aluminium alloy temperature need to be improved within the scope of 690 DEG C -710 DEG C in furnace, production cost and energy consumption is all higher, production efficiency is low.
It is in industry it was verified that guarantee casting can form and guarantee consistency under the premise of, liquid aluminium alloy temperature it is more low more
It is good, it is therefore necessary to invent a kind of casting technique that can ensure casting quality qualification under cryogenic.
Summary of the invention
