Die-casting die with cooling mechanism and using method of die-casting die

Abstract

The invention relates to the technical field of die-casting dies, and discloses a die-casting die with a cooling mechanism and a using method of the die-casting die. The die-casting die comprises a fixed die insert and a movable die insert, the fixed die insert and the movable die insert are connected through a guide rod, and fixing pieces are arranged on the opposite circumferential sides of the fixed die insert and the movable die insert. According to the die-casting die with the cooling mechanism, after high-temperature liquid metal is injected into a die groove, a movable die is rapidly heated, cold water in a water storage cavity is rapidly heated and boiled to generate a large amount of steam, the steam is collected in a gas collection chamber, a separation pipe is used for separating water vapor from water, the water vapor is led into the gas collection chamber, the water flows back into the water storage cavity through through holes in a separator and is discharged through a water outlet, cold water is introduced through a water inlet formed above the bottom of the separation pipe all the time, so that part of water vapor in the separation pipe is liquefied into water when being cooled, and the damage to water cooling equipment caused by the fact that the water vapor and the water are discharged through the water outlet after being rapidly formed is avoided.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold with a cooling mechanism and a use method thereof. Background technique [0002] Die-casting mold is a method of casting liquid die forging, a process completed on a special die-casting die forging machine, its basic process is: the metal liquid is cast into the cavity of the mold at low or high speed, and the mold has The active cavity surface, which is press-forged with the cooling process of the molten metal, not only eliminates the shrinkage cavity and shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. [0003] During die-casting, the water-cooling mechanism installed inside the mold is used to accelerate the cooling of the die-cast metal workpiece to achieve the solidification of the metal workpiece and the cooling of the mold. However, since the liquid metal is 500-1500...
