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.

A die casting machine of an embodiment includes: a holding furnace holding molten metal; a sleeve located outside the holding furnace and having a molten metal supply port passing through a mold; a plunger sliding through the sleeve and including a plunger rod and a plunger tip fixed to a tip of the plunger rod; a molten metal supply pipe pushed against the sleeve to cover the molten metal supply port and supplying the molten metal into the sleeve; and a pushing force variable mechanism reducing a pushing force for the sleeve in the molten metal supply pipe when the plunger is sliding.

A pressure receiving pin includes a fitting portion in a through hole of a fixed mold that communicates with a portion of an exhaust passage on an inlet side, a columnar distal end portion located coaxially with the fitting portion while closer to the exhaust passage that slides with respect to the through hole upon reception of molten metal, and an intermediate portion also located coaxially between the fitting portion and the distal end portion and that has a diameter smaller than a diameter of the distal end portion. An air supply device supplies air when a movable mold is opened such that the air passes through gaps formed between an outer peripheral surface of the intermediate portion and an inner peripheral surface of the through hole and between the distal end portion and the fixed mold, and flows out to the movable mold.

The present invention discloses a new process for the injection of metallic materials into polymer-based moulds, the mould itself required for a process of this nature, and the apparatus which will execute the process and will employ the mould, in such a way that moulds with greater or lesser properties of flexibility are subjected to a pressurised injection of metal thereon, it being possible to adjust and coordinate the parameters of pressure, flowrate, closure of the mould, and the conditions of the material, thanks to a new polymer-based mould which adapts its configuration to the rest of the system and to the pressurised injection of the material.

A die casting machine is provided with a movable platen for holding a movable mold, a stationary platen for holding a stationary mold, and tie bars inserted into insertion holes provided in the movable platen and the stationary platen, the movable platen being arranged so as to be capable of advancing to and retreating from the fixed platen along the tie bars. A hollow section is provided in at least one of the movable platen and the stationary platen.
