Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to a die-casting machine for aluminum alloy parts. Background technique [0002] Die casting is a metal casting process characterized by the application of high pressure to molten metal using the cavity of a mold. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is used. [0003] Because aluminum alloy has a good elongation rate and is lighter than other metals, it is favored by many industries, and aluminum alloy die-casting parts are also widely praised by the market. However, when the current die-casting equipment for aluminum alloy parts is cast at low mold temperature, When the a...

[0003] Because aluminum alloy has a good elongation rate and is lighter than other metals, it is favored by many industries, and aluminum alloy die-casting parts are also widely praised by the market. However, when the current die-casting equipment for aluminum alloy parts is cast at low mold temperature, When the aluminum liquid is flowing in the runner, the aluminum liquid in the front is cooled, it is easy to form an oxide film, and it is easy to solidify on the protruding part far from the gate. Due to the increased pressure, wrinkles are formed on the surface, resulting in unqualified products, and usually in the injection molding process. In the process of heat exchange between the aluminum alloy parts and the outside world in the mold, cooling is achieved, and the cooling process is slow. In the aluminum alloy parts manufacturing industry, the existing aluminum alloy parts die-casting machines are prone to produce oxide films and slow cooling. In the actual production process It is easy to cause the problem of unqualified products and low production efficiency
