An aluminum alloy die-casting mold with rapid cooling and cooling function

Abstract

The invention discloses an aluminum alloy die-casting die with a rapid cooling function, and belongs to the technical field of die-casting dies. The aluminum alloy die-casting die with the rapid cooling function comprises a bottom plate, a lower die plate and an upper die plate, wherein a sliding plate is slidably connected onto a limited rod; the upper die plate is connected to the bottom part ofthe sliding plate; a water channel, a first cooling water channel and a third cooling water channel are dug in the lower die plate; second cooling water channels are dug on the sliding plate and theupper die plate; and two ends of the second cooling water channels penetrate through the sliding plate and are matched with the first cooling water channel and the third cooling water channel. According to the aluminum alloy die-casting die with the rapid cooling function provided by the invention, the die can be comprehensively cooled, so that the cooling speed is accelerated; and then the die can be cooled again through a cooling fan, so that an effect on quickly cooling is achieved, the production efficiency of castings is improved, the quality of the castings is ensured, and the giant economic loss caused to a die use enterprise is avoided.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to an aluminum alloy die-casting mold with a rapid cooling function. 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] When die-casting a mold, molten metal is injected into the mold cavity, releasing a large amount of heat in a very short period of time, which increases the temperature of the mold. Cooling measures are required to cool the mold. Existing die-casting molds usually use ...

Problems solved by technology

[0003] When die-casting a mold, molten metal is injected into the mold cavity, releasing a large amount of heat in a very short period of time, which increases the temperature of the mold. Cooling measures are required to cool the mold. Existing die-casting molds usually use water cooling. Cool the mold, but the current water-cooling method usually only cools the upper or lower mold plate alone, which cannot fully cool the mold, and the cooling capacity is insufficient, thus reducing the production efficiency of the casting, and cannot guarantee the quality of the casting , which in turn causes huge economic losses to mold users
