Abstract
A light metal injection molding machine includes a melting unit, a material supply device, and an inert gas supplier. The material supply device includes a supply cylinder and a lower shutter. The supply cylinder includes a passage which communicates vertically, a supply opening disposed on an upper side of the passage and to which a molding material is fed, and a discharge opening which is disposed on a lower side of the passage and discharges the molding material to a material supply port of the melting unit. The lower shutter is disposed in the supply cylinder to open and close the passage, and the molding material is placed on the lower shutter when the passage is closed. The lower shutter has at least one vent-hole that allows an inert gas supplied from below the lower shutter to pass when the passage is closed.
