摘要： An injection molding apparatus of a metal material places a heating cylinder in an inclined position. The heating cylinder includes a nozzle at a tip thereof and a screw disposed inside. In this way, the metal material in a liquid phase state can be transferred and metered accurately in a reliable manner at all times by flowing due to the inclination and a transfer force produced by rotation of the screw. A clamping apparatus is provided to oppose the injection apparatus and includes a mold having a sprue bush inside. The injection apparatus and the clamping apparatus are placed on an apparatus platform in an inclined position at the same angle with the mold in a lower end, so that the metal material in the liquid phase state in the heating cylinder flows down toward the head due to self-weight. The nozzle and sprue bush are positioned on the same straight line, thereby maintaining nozzle touch without bending the nozzle.

摘要： An injection screw comprise a rear end to a front end of an effective length of the screw compartmented in the order of a feed zone, a compression zone and a metering zone, wherein the metering zone is constituted by the first metering zone, the second metering zone and the relaxation zone. A root diameter of the second metering zone is formed in a smaller diameter than a root diameter of the first metering zone and a screw channel depth is set deeper than a screw channel depth of the first metering zone. Variations in a resin temperature at injecting is solved and melting and kneading through a entire screw further are improved by only partial changing of the configuration of the metering zone.

摘要： An improved method of manufacturing a multilayer molding having a core and a surface layer by means of a double nozzle structure can eliminate a damaging phenomenon of producing a mixture of a resin material for forming the core remaining in and out of the aperture of the inner nozzle of the double nozzle structure and a resin material for forming the surface layer in the initial stages of molding operation by effectively driving back the remaining resin into the inner nozzle. A double nozzle structure that can suitably be used with such a method includes a shut-off pin arranged in the inner nozzle disposed at the center of the outer nozzle. The resin material for forming the core is driven out simultaneously with the resin material for forming the surface layer coming from the outer nozzle. The operation of resin injection from the inner nozzle is terminated at an arbitrarily selected moment during the operation of injecting the resin material for the surface layer of the outer nozzle. Then, the inside of the inner nozzle is brought into a no-load condition while the shut-off pin is held to its open position. Thereafter, the remaining resin material for the core found in and out of the aperture of the inner nozzle is driven back into the inner nozzle by the pressure of the resin injected from the outer nozzle. Finally, the inner nozzle is closed by the shut-off pin and the injecting operation of the outer nozzle is terminated.

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.
