Description
Technical field
The present invention relates to die casting field, more particularly to a kind of biliquid composite casting side for automobile die cast
Method.
Background technology
Automobile die is to complete auto parts and components shaping, the critical equipment of auto output is realized, in the exploitation of automobile, vapour
Important responsibility is responsible in the remodeling of car.A brand-new vehicle takes around 350-400 set car panel dies, and value is super
Cross one hundred million.And the car panel die that a remodeling car averagely there are about 25% needs to change, the mould value of replacing also reaches
To tens million of.One of the important measure of major car manufacturer all using cycle of raising automobile listing as raising competitiveness,
Requirements at the higher level thus are proposed to the renewal time of car panel die and quality.
The casting of mould needs the material being easily molded with other in advance, makes comprising one as die structure size
The casting mold of cavity, mobility liquid then is poured into a mould in casting mold cavity again, it is default with regard to that can form after liquid cooling solidification
The mould of structure snd size.Running gate system is to cast the passage that liquid enters die cavity.Rational injection system structure is for ensureing to cast
Part quality plays critically important effect, and running gate system and molten metal fluidised form, the discharge of type intracavity gas etc. are closely related, and can be right
Filling speed, filling time, cavity temperature etc. are filled type condition and played regulatory role, but irrational running gate system can cause gas
The defects of hole, shrinkage cavity and porosity, cold shut and poor surface smoothness.
During biliquid composite casting, two kinds of casting liquid can neither rush mixed, and punching is mixed to reduce high-rigidity cast liquid material
Purity, so as to reduce the mechanical performance of work package, cold shut, oxide inclusion defect can not occur in two kinds of metal faying faces again.
But traditional biliquid composite casting method be all be superimposed using single two apparatus for pouring realize biliquid composite casting into
Type, easily cause two kinds of casting liquid to rush mixed or cold shut, oxide inclusion defect, influence the quality of biliquid compound casting.
Therefore, invent that a kind of have very much must to solve the above problems for the biliquid composite casting method of automobile die cast
Will.
The content of the invention
It is above-mentioned to solve it is an object of the invention to provide a kind of biliquid composite casting method for automobile die cast
The problem of being proposed in background technology.
