This mechanism is composed of an attachment which contacts with a molten metal feeding port of the sleeve to block it so as to bring a sleeve inside to a closed condition, a vacuum device sucking air from the sleeve inside through the attachment, and a powder feeding device discharging the powder lubricant together with air from a nozzle into the sleeve inside through the attachment.
