Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a zinc alloy die-casting mold. Background Art

[0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal in the mold cavity. The mold is usually made of a higher strength alloy. The die casting mold is a tool for completing the die casting process on a special die casting die forging machine. It is divided into many types according to its material. Among them, the zinc alloy die casting mold has good room temperature mechanical properties and wear resistance and good castability, so it is a very common type of die casting mold. In order to cool the product in the die casting mold, a cooling cavity is generally set in the die casting mold. When the zinc alloy die casting mold is in use, the mold and the product are cooled by the coolant flowing in the cooling cavity. The coolant can generally be recycled. When the die casting mold is used continuously for a long time, the temperature of the coolant will gradually increase and the cooling effect will decrease. Therefore, a zinc alloy die casting mold is proposed to facilitate the cooling of the die casting mold, the product and the coolant. Utility Model Content
