摘要： A receiving chamber receives a material heated in a heating chamber. An injecting shaft of an injecting machine slurries the material crushed by cutters downstream of the receiving chamber and feeds the slurried material to an injection port formed between the fore ends of the shaft and injecting chamber so that the slurried material is gradually accumulated in the port. The shaft is retracted by counteraction from the slurried material accumulated in the port, over a distance proportional to a current accumulated amount of the material in the port. The current accumulated amount of the material in the port can be detected from a current position of the shaft, and then it is determined whether the detected current accumulated amount has reached a predetermined amount. When the current accumulated amount has not reached the predetermined amount, the cutters and injecting shaft are further driven until the predetermined amount is reached. The receiving chamber has a pair of passage sections on its outer surface in opposed relation to each other, which function both as light beam passages for light emitting and receiving elements that are provided on the sections for detecting whether a heated material is in the receiving chamber, and as inert gas supply passages to direct inert gas into the receiving chamber.

摘要： An upper unit of an injecting molding apparatus includes an ingot entry for introducing into the apparatus an ingot to be molded and an ingot heating chamber for heating the ingot supplied via the entry, and a lower unit includes a crusher for crushing the heated ingot and an injecting machine having an axially movable screw shaft for slurring and injecting the crushed ingot into a mold. The upper and lower units are interconnected via a flexible connector unit which is flexible in a vertical direction to allow the lower unit to vertically displace relative to the upper unit. By disengaging the connector unit from the upper unit, the lower unit can be disconnected from and laterally pivoted with respect to the upper unit to permit easy access to both the units. This displacement of the lower unit permits facilitated maintenance operations of the apparatus. A lower door provided for openably closing an ingot exit hole of the heating chamber is a vertically pivotable door that does not require a large operating space.

摘要： A heating machine for heating an ingot of a metal such as a magnesium alloy. The heating machine has a heating chamber equipped with a RF induction coil capable of swinging about a horizontally axis. The coil is placed horizontally, and the metal ingot is fed into the coil from an introduction chamber by a pushrod. Stoppers prevent the ingot from falling from the RF induction coil when it is switched from its horizontal posture to its vertical posture. The coil is wound on a cylindrical member. A rotatable hollow shaft is firmly mounted to the holder in a perpendicular relation to a substantially axially central portion of the cylindrical member. A part of the coil is inserted in the hollow shaft via an insulating material. The rotatable hollow shaft is swung by a swinging mechanism. The induction heating coil is wound on a ceramic holder. A metal ingot is inserted in the holder with a given clearance. A plurality of pillars of L-shaped cross section are fitted over the holder to place it in position vertically and horizontally.

摘要： A predetermined amount of molten metal 12 is supplied to a heat-insulating crucible 18. After that, a chill block 46, which is cooled to a predetermined temperature of not more than a temperature of the molten metal 12, is immersed and rotated in the molten metal 12. Accordingly, the molten metal 12 is agitated while being cooled to give no directivity of cooling. It is possible to obtain semisolidified metal 20 which is formed into slurry uniformly and effectively as a whole. The semisolidified metal 20 is discharged from the heat-insulating crucible 18, and it is supplied to a forming machine 22 to apply a forming treatment thereto. Accordingly, it is possible to produce the desired slurry efficiently and economically.
