カスト成形機を提案するものである。[Detailed Description of the Invention] (Industrial Application Field) Advantageous die-casting of metal workpiece materials including high melting point metals such as iron-based or copper-based metals and alloys, as well as metal matrix composites thereof. In this regard, the present invention proposes a die-casting method and a die-casting machine for solid-liquid coexisting metals, which can advantageously perform die-casting of this kind of difficult-to-process materials.
（従来の技術）

広く用いられている。(Prior art) Conventional die casting technology generally involves feeding the molten metal of the metal workpiece into a sleeve that forms the inlet of a die casting molding machine, and then injecting it into the cavity of the die casting mold using an injection cylinder. The injection system used to pressurize the hot metal supply is divided into two types: a cold chamber type that is independent from the molten metal holding furnace, and a hot chamber type that is installed immersed in the molten metal holding furnace. The former is widely used mainly for aluminum alloys, and the latter is mainly used for zinc and magnesium alloys.
（発明が解決しようとする課題）
従来のダイカスト成形機は上記のように溶湯をスリーブ
に給湯する方式なので、この溶湯の温度は当然、融点よ
りもかなり高い。このためアルミニウム合金や亜鉛合金

い合金のダイカスト鋳物に適用しようとすると金型寿命
が著しく短（なり、とくに鋼はさらに高融点合金である
のでこれについての適当な金型材料が見当らない。(Problem to be Solved by the Invention) Since the conventional die-casting machine uses a system in which molten metal is supplied to the sleeve as described above, the temperature of this molten metal is naturally much higher than its melting point. For this reason, die castings made of low melting point alloys such as aluminum alloys and zinc alloys can be obtained relatively easily, but when applied to die castings made of alloys with high melting points such as copper alloys and cast iron, the mold lifespan is limited. However, since steel is an alloy with a high melting point, no suitable mold material has been found for this purpose.
このことはまた、溶湯を受湯しダイカスト金型へ導入す

口を塞いで金型内への射出ができなくなる。On the other hand, semi-solid metals, which have recently been under development and research, have a relatively low temperature, and their use in die-casting will considerably alleviate the problem of heat resistance of mold materials. However, as mentioned above, regardless of the type of die-casting machine, it is assumed that the raw material molten metal is stocked in a tank. Therefore, if the semi-solid metal obtained by the semi-solid metal manufacturing equipment is stored in a heat insulating tank with the same mechanism, the crystal grains of the semi-solid metal will enlarge in the heat insulating tank over time, and this will cause the die-casting product to deteriorate. Not only does the quality deteriorate, but the enlarged crystal grains block the sprue and make it impossible to inject into the mold.

共存金属のダイカスト成形機（第２発明）である。(Means for Solving the Problems) The above objects of the present invention are advantageously satisfied by the following configuration. That is, a metal workpiece is inserted in a solid state into the casting hole of a die-casting mold, the metal workpiece is electrically or electromagnetically heated to a solid-liquid coexistence state, and then heated to the hot water of the die-casting mold. A method for die-casting a solid-liquid coexisting metal (first invention), characterized by injecting the metal into the internal cavity of a die-casting mold through a channel (first invention), and a movable mold attached to a movable platen and a fixed mold attached to a fixed platen. The stationary platen has a casting port connected to the internal cavity of the die-casting mold through a solid runner, and the tip of the injection plunger energized by the injection cylinder fits into this casting port. , a die-casting machine formed by connecting sleeves, and the casting port is equipped with electricity that surrounds the sleeves and raises the temperature of the metal workpiece in a solid state, which is charged into the sleeves, to a temperature in the solid-liquid coexistence region. This is a die-casting machine for solid-liquid coexisting metal (second invention), characterized in that it is equipped with a magnetic or electromagnetic heating means.
（作 用）
ここに金型およびスリーブ材料の耐熱寿命延長について
は、一般に溶湯は通常その融点よりも２０〜５０℃高温
であるが、その代りに固液共存状態の金属被加工材を射
出成形するときこの加工材は溶湯と比べて温度がより低
く、潜熱も小さい。(Function) In order to extend the heat-resistant life of the mold and sleeve material, the temperature of the molten metal is generally 20 to 50 degrees Celsius higher than its melting point, but instead of that, injection molding of a metal workpiece in a solid-liquid coexistence state is used. At this time, the temperature of this processed material is lower than that of the molten metal, and its latent heat is also small.
いうまでもなく金型の寿命は温度が高くなると急激に短
くなるので、温度がより低く、潜熱の小さい被加工材を
ダイカスト鋳物成形に用いることにより、スリーブおよ
び金型への伝熱が小さくなり、それにより金型寿命が長
くなる。Needless to say, the life of the mold will rapidly shorten as the temperature rises, so by using a workpiece material with lower temperature and less latent heat for die casting, the heat transfer to the sleeve and mold will be reduced. , thereby extending the mold life.
次に固液共存状態における金属被加工材の結晶粒肥大化
は、その固液共存状態の保持時間を短くすればよい。（
結晶粒肥大化は固液共存域保持時間に比例する）。そこ
で、固相材をダイカスト機内に設置した加熱装置で固液
共存状態へ加熱し、これを金型内へ射出することが必要
となる。Next, enlarging the crystal grains of a metal workpiece in a solid-liquid coexistence state can be achieved by shortening the holding time in the solid-liquid coexistence state. (
Grain enlargement is proportional to the retention time in the solid-liquid coexistence region). Therefore, it is necessary to heat the solid phase material to a solid-liquid coexistence state using a heating device installed in the die-casting machine, and then inject it into the mold.

成形機と基本的に異なるところはない。(Example) As FIG. 1 schematically shows an example of a semi-solid metal die-casting machine according to the present invention, this example shows a case in which a heating induction coil 7 is installed in the die-casting machine.
If the material is a low melting point alloy, a resistance heating heating element may be used in place of the heating induction coil 7; in any case, except for the provision of such heating means, it is basically the same as a conventional die casting machine. There is no difference in terms.

Note that the material 8 is inserted into the induction coil 7 by advancing the plunger tip 10, and is heated to a solid-liquid coexistence region at that position. When the material 8 being heated reaches a predetermined solid phase ratio,
A plunger tip 10 injects this material 8 into a die-casting mold to perform molding.

なる。(Effect of the invention) Die casting in the solid-liquid coexistence region can be formed at a lower temperature than conventional molten metal die casting, which not only extends the life of the mold and reduces manufacturing costs, but also enables molding of high-melting point metals, which were conventionally considered impossible to die-cast. Die-casting becomes possible.
