摘要： The invention has an object to permit to make the accumulation amount and the temperature of molten metal in the metal material molding machine constant, by performing material supply and melting taking the accumulation amount as reference during the molding operation. The supply apparatus 11 and the agitation means 29 of metal material at the moment of operation starting are controlled to be inactive until the temperature of the melting vessel attains a predetermined value and to start operating when the predetermined temperature is attained, allowing to supply and agitate the metal material. The supply and the agitation of metal material after the predetermined temperature is attained, are performed while gradually supplying and agitating the metal material until metal material of at least 6 times or more of the maximum injection volume is accumulated in melt state.

摘要： Upward variations of a molten metal level in a container for melting metallic material shall be carried out by detecting variations of a liquid level inside a detector connected to a gas-pipeline, wherein a rise in the pipeline pressure causes the liquid level to move down. Communication is established by means of a gas-pipeline 13 for inert gas between that portion of a container for melting metallic material which is above a molten metal surface 15a and that portion of a detector 16 comprising a transparent tubular container 18 which is above a liquid surface 17a. Variations of the liquid level 17a inside the detector 16 due to a rise in the pressure inside the above-mentioned gas-pipeline 13 are detected as upward variations of the level of the molten metal surface.

摘要： There is provided an injection apparatus comprised of a heating cylinder which is closed by a front end member having a nozzle. The apparatus is further comprised of a plasticating screw in the heating cylinder in a freely rotating and reciprocating manner, and a plunger connected to the front end of the screw. The plunger has a conical front end in which flow channels are formed. The front end member has a measuring chamber formed therein at an internal central location thereof. The measuring chamber has a predetermined length and an internal diameter which is reduced by 8 to 15% with respect to an internal diameter of the heating cylinder. The diameter of the injection plunger is set almost equal to the diameter of the measuring chamber, whereby the injection plunger is inserted into the measuring chamber in a freely reciprocating manner. A gap is formed on the external peripheral surface of the plunger due to the difference between the heating cylinder internal diameter and the plunger diameter, and the gap functions as a plastication-accelerating block. The block is formed so as to have a distance longer than an injection stroke, whereby uniform plastication is achieved and uneven temperature in the material is eliminated. Further, the plunger advance blocks the gap, which leads to uniform density and precise measurement of the material.

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.

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.
