Aluminum alloy die-casting die easy to rapidly cool

Abstract

The invention discloses an aluminum alloy die-casting die easy to rapidly cool, and belongs to the field of die-casting dies. According to the aluminum alloy die-casting die easy to rapidly cool, after the die is used for die-casting of aluminum alloy liquid, heat in the alloy liquid is adsorbed by a copper net and transmitted to air stretching sleeve rods, so that air stretching bags are heated and transversely expands at present, the contact area of the air stretching bags and an adherent heat pipe is increased, then the air stretching bags continue to expand downward under the action of heat to drive the adherent heat pipe to move down and gradually extend to a heat reducing chamber, so that the air stretching sleeve rods are dislocated with the adherent heat pipe; and compared with the prior art, according to the aluminum alloy die-casting die easy to rapidly cool, the contact area of condensate water in the heat reducing chamber is significantly increased, the cooling is faster, the die-casting efficiency of aluminum alloy is effectively improved, in addition, in cooperation with the effect of a water stirring rod, the water stirring capacity in the condensate water is effectively improved, the condensate water below the multiple air stretching sleeve rods is in a certain shaking state, and the heat taking-away effect is better.

Description

technical field [0001] The invention relates to the field of die-casting molds, in particular to an aluminum alloy die-casting mold that is easy to rapidly cool down. Background technique [0002] Die-casting mold is a tool for casting metal parts, a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is: the molten metal is first cast at a low or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which eliminates the shrinkage of the blank. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved. [0003] The alloys used in die castings are mainly non-ferrous alloys, and ferrous metals (steel, iron, etc.) are rarely used due to mold materials and other issues....

AI Technical Summary

Problems solved by technology

After die-casting, it is necessary to wait for the aluminum alloy liquid to cool down, so that the casting can be molded before it can be demolded. Then, due to the high temperature of the alloy liquid in the molten state, it takes a long time to cool down, which affects the die-casting efficiency.
