Description
Technical field
The present invention relates to extrusion casint equipment manufacturing field, and in particular to a kind of protection extrusion casting apparatus clamping mechanism
Device and method.
Background technique
Extrusion casint is that a certain amount of molten metal is directly poured into pressure chamber, and packed type chamber under the action of extrusion piston,
Under the effect of mechanical static pressure, High Pressure Solidification and a small amount of plastic deformation occurs, so that a kind of metal for obtaining blank or part adds
Work method.Since performance and the preferable spray of internal soundness can be obtained using Extrution casting technique, using the work
The cast product of skill forming is widely used in the manufacturing fields such as space flight, automobile, weaponry；
Extrution casting technique can be divided into two kinds of forms of Direct Squeezing Casting technique and indirect Squeeze Casting Technology, wherein straight
Connecing extrusion casint is that molten metal is directly poured into open concave die, is later closed punch mold and concave die, makes
Molten metal solidifies under the action of punch-pin, since mold is in opening-wide state to the process form before and after molten metal casting, because
This, is unable to satisfy the forming needs of intricate casting, and casting dimension accuracy is also relatively low；Indirect Squeeze Casting Technology is to develop in recent years
Extrution casting technique method, with Direct Squeezing Casting it is maximum difference be molten metal bath casting front mold be in be closed
State, therefore, the technique can meet the forming needs of Complicated structure casting, and casting dimension accuracy is also higher；
