Description

Technical Field

[0001] This utility model relates to the field of spraying mechanism design technology, specifically a spraying mechanism for a die-casting mold. Background Technology

[0002] Die casting is a type of pressure-cast part. It involves using a pressure casting machine equipped with a casting mold. Molten copper, zinc, aluminum, or aluminum alloy is poured into the machine's feed inlet, and the casting process produces copper, zinc, aluminum, or aluminum alloy parts of the shape and size specified by the mold. During the die casting production process, a spraying robot is used to spray-coat the die castings. Spraying protects the outer surface of the die castings, extending their service life. The spraying mechanism on the robot typically includes a robotic arm, atomizing nozzle, liquid delivery pipe, drive head, and workpiece seat. To facilitate this spraying process, a spraying mechanism for the die casting mold is required.
