Technical Field

The invention relates to the technical field of aluminum alloy processing, in particular to a die-casting device with a cold pressing assembly for aluminum alloy die-casting and an implementation method thereof.

Background

Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing an inner cavity of a die. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. Most die cast parts are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine may be used. The casting equipment and molds are expensive to manufacture, and therefore the die casting process is typically only used to mass produce a large number of products. It is relatively easy to manufacture die-cast parts, which typically require only four main steps, with a low incremental cost alone. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one of various casting processes. Compared with other casting technologies, the die-cast surface is smoother and has higher size consistency. Cold chamber die casting may be used when die casting metals that cannot be used in the hot chamber die casting process, including aluminum, magnesium, copper, and zinc alloys with higher aluminum content. In this process, the metal needs to be melted away first in a separate crucible. A quantity of molten metal is then transferred to an unheated injection chamber or nozzle. These metals are injected into the mold by hydraulic or mechanical pressure. The biggest disadvantage of the prior art process is the long cycle time due to the need of transferring the molten metal into the cooling chamber, so that the temperature of the die casting is slowly reduced and the die casting efficiency is low.
