Description

Technical Field

[0001] The utility model relates to the technical field of die casting processing, in particular to a trimming mechanism used for the production of aluminum alloy die castings. Background Art

[0002] Die casting is a kind of pressure casting part. It uses a pressure casting mechanical die casting machine equipped with a casting mold to pour the heated liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts of the shape and size limited by the mold. Such parts are usually called die castings. In the production process of aluminum alloy die castings, a trimming mechanism is required to trim the die castings.
