    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.

    摘要翻译： 接收室接收在加热室中加热的材料。 注射机的注射轴将由接收室下游的切割器粉碎的材料浆化，并将浆状材料供给到形成在轴和注射室的前端之间的注射口，使得浆料逐渐积聚在口中。 通过与积聚在端口中的浆状材料相反的距离缩回轴，该距离与端口中材料的当前累积量成比例。 可以从轴的当前位置检测端口中的材料的当前累积量，然后确定检测到的当前累积量是否已经达到预定量。 当当前累计量未达到预定量时，进一步驱动切割器和注射轴直到达到预定量。 接收室在其外表面上具有彼此相对的一对通道部分，其作为用于发光和接收元件的光束通道，其用于检测被加热材料是否在接收室中 ，以及作为将惰性气体引入接收室的惰性气体供给通路。

    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： 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.
