    • The present invention relates to a method of molding a low-melting-point metal alloy. In this method, a remaining semisolid material at the end of molding is heated to a liquidus temperature or higher to be melted. Then an injection of the material is performed in a perfectly molten material state to discharge it from a heating holding cylinder. Heating is stopped and a molding operation is finished. A discharge of a remaining semisolid material is made while supplying a metallic raw material having the same composition as the molding material. A temporary suspension of molding is performed after the temperature of the heating holding cylinder is increased to a liquidus temperature or higher and an accumulated semisolid material is in a perfectly molten material state. At the resumption of molding, the temperature of the heating holding cylinder is lowered to the original temperature in the solid-phase and liquid-phase temperature region while performing a discharge of a perfectly molten material by the injection thereof and a supply of a molding material. After the inside of the heating holding cylinder is replaced with the supplied molding material, molding of the material is started. According to the invention, problems of remaining materials at the end of an operation in case where using a low melting point metal alloy, which exhibits thixotropy properties in a solid-phase and a liquid-phase coexisting temperature region, as a molding material, the material is melted to a semisolid material to be injection-molded, and at a temporary suspension of the molding therein, are solved by discharging the material in a perfectly molten material state.
    • 本发明涉及一种低熔点金属合金成型方法。 在该方法中,将成型结束时的剩余半固体材料加热至液相线温度以上以熔融。 然后在完全熔融的材料状态下进行材料的注射,以将其从加热保持筒中排出。 加热停止,成型操作结束。 在提供与成型材料具有相同组成的金属原料的同时,制备剩余的半固体材料的排出。 在将加热保持筒的温度升高到液相线温度以上并且蓄积的半固体材料处于完全熔融的材料状态之后,进行成型的暂时悬浮。 在恢复成型时,通过注入熔融材料的排出,同时供给成型材料,将加热保持筒的温度降低到固相和液相温度区域的初始温度 。 在用所提供的模制材料替换加热保持筒的内部之后,开始模制材料。 根据本发明,在使用在固相和液相共存温度区域具有触变性的低熔点金属合金作为成型材料的情况下,在操作结束时的剩余材料的问题, 材料被熔化成待注射成型的半固体材料,并且在其中的模制物的暂时悬浮液中,通过以完全熔融的材料状态排出材料来解决。

    • A method of molding a low melting point metal alloy which exhibits thixotropy properties at a solid-liquid coexisting temperature, said method comprising the steps of heating said metal alloy at a temperature in the solid-liquid coexisting temperature region to form a semisolid, supplying said semisolid to a heating/holding cylinder to be accumulated, and injecting said semisolid into a mold. At the end of the molding process, a remaining semisolid material is heated to a wholly molten state, then discharged by injection, and heating is stopped so that the molding operation is finished; or, at a temporary suspension of molding, an accumulated material is heated to a wholly molten state and, at the resumption of molding, the temperature of the heating holding cylinder is lowered to the original solid-liquid coexisting temperature region while discharging said wholly molten material by injection and resupplying with new semisolid molding material.

    • The present invention relates to a method of molding a low-melting-point metal alloy which exhibits thixotropy properties in a solid-phase and liquid-phase coexisting temperature region. In this method, a temperature of a heating holding cylinder is increased to a liquidus temperature or higher at the start of a molding operation. Then a remaining material in the preceding molding remaining in the heating holding cylinder in a solid state is perfectly melted. After that a temperature of the heating holding cylinder is lowered to a temperature in the solid-phase and a liquid-phase coexisting temperature region. At the same time a molding material is supplied and a provisional molding is carried out. After the temperature has reached the solid-phase and liquid-phase coexisting temperature region, a regular molding is started. By the present invention a problem of a remaining material in the heating holding cylinder, which becomes a trouble at the start of molding by injection is solved.
