摘要： An injection molding machine for low-melting point metallic material has an injection mechanism having a tip portion, a melting cylinder and a rear portion holding a drive mechanism. The tip portion has a weighing chamber and a nozzle member feeding a mold. The melting cylinder is held at an oblique angle to promote gravity flow of the molten metal toward the tip portion. The melting cylinder encloses an agitating and injection mechanism that rotates and advances or retreats freely within the cylinder. One agitating and injection mechanism has a hollow shaft surrounding an injection rod tipped by an injection plunger that moves lengthwise in the shaft and agitating wings disposed around the tip end of the hollow shaft. The wings reach the inner sides of the cylinder and rotate. The plunger may extend beyond the shaft to be inserted in the weighing chamber.

摘要： The purpose of this invention is to prevent sludge from flowing into a measuring chamber by partitioning the inside of a melt cylinder into a melt stirring part and a molten metal flow passage part, and to stabilize supply of the metallic material and measurement of the molten metal. A nozzle member 14 of which the inside of the rear part is formed into a measuring chamber 13 is attached to the tip of a melt cylinder 11. The end face of the opening periphery of the measuring chamber 13 of the nozzle member 14 faced to the inside of the melt cylinder is projectingly formed into a ring-shaped bearing 14b. A hollow stirring shaft 16 provided with stirring blades 15 on the outer periphery is supported by the bearing 14b and a bearing member 21 in the rear end of the melt cylinder so as to be freely rotatable with a suction port 25 bored in the side wall of the tip part. An injection rod is put into the stirring shaft and a plunger 17 with a ring valve on the tip is fitted into the measuring chamber 13 so as to be freely movable forwards and backwards. The inside of the melt cylinder is partitioned into a melt stirring part A and a molten metal reservoir B by the stirring shaft 16. The meting cylinder 11 is installed slantwise on the machine base with the nozzle member side downward to use the tip part as a sludge receiver 27.

The driving device is disposed on the rear end of the melting cylinder for driving the injection device and includes a pedestal movable to advance and retreat freely to support the injection mechanism obliquely. A nozzle touch block on a tip end portion of the pedestal is touched obliquely by the nozzle member of the melting cylinder. A frame on a rear portion of the pedestal supports a rear portion of the injection mechanism and the driving device obliquely. A nozzle touch device touches an injection nozzle to a mold in the mold clamping mechanism by moving the pedestal with the injection mechanism toward the mold clamping mechanism.

摘要： An injection method and apparatus for melted metals are provided to transfer the metals, to melt them by external heat, and to meter and degas the metals by employing a reservoir to reserve metals in liquid phase. The injection apparatus includes a heating cylinder having a fore end portion which communicates with a nozzle member and of which internal diameter is made smaller to serve as a metering chamber, and an injection screw installed within the heating cylinder to be movable and rotational. A reservoir for reserving melted metals in liquid phase has an axis provided between the plunger and a feeding portion containing a screw flight around the axis. A projected portion for limiting the feeding of granular metals flowing to the reservoir and for preventing the metals in liquid phase from flowing backward during injection is provided on a boundary between the feeding portion and the reservoir.

摘要： A method of metering a metal material in a liquid phase in molding injection provides accurate and reliable transfer of the metal material. A heating cylinder housing a rotatable and axially movable screw, is inclined with its head pointing downward, so that the metal material in the liquid phase state flows down into a front chamber due to self-weight. At the forward position after injection, the screw is forced to retract to a set position, whereby a predetermined quantity of a liquid phase material primarily stored on the periphery of the head portion of the screw is accumulated by suction due to a negative pressure in the front chamber of the heating cylinder. Further, a constant quantity of the liquid phase material can be metered each time in the front chamber by stopping and then rotating the screw at a retraction position.

A oxidation prevent method of melting metal material by a melting vessel 1 comprising inside a rotatable agitation member 8, having a weighing chamber 4 communicating with a nozzle member 2, and an injection member 9 advanceably and retractably inserting an extremity injection plunger 12 passing through the agitation member 8 in the weighing chamber 4, and the melting vessel being installed on a slant with the nozzle member 2 downside. The space area over the melted metal surface 15a of the melting vessel 1 is made into inactive gas atmosphere. The oxygen concentration in this space area is measured and monitored. It is judged as error when the measured oxygen concentration exceeds a predetermined reference value, and heating and material supply are suspended to prevent the melt metal from oxidizing.
