装置に関するものである。Detailed Description of the Invention (Industrial Application Field) This invention is an induction melting method for die casting that instantaneously supplies molten metal of the alloy press-fitted into a die in the production of die-cast products made of aluminum alloy, zinc alloy, etc. This invention relates to a holding device.
（従来の技術）
従来、アルミニウム合金等のダイカスト製品の製造は次

その他のリターン材等７４が適宜投入されて溶湯が調製
された。(Prior Art) Conventionally, die-cast products such as aluminum alloys have been manufactured as follows. The first method is near the die-casting machine 7I, as shown in FIG. This holding furnace 72 is provided,
A large parent furnace or melting furnace 73 was installed apart from the holding furnace 72, and commercially available ingots and other return materials 74 were appropriately charged into the parent furnace 73 to prepare molten metal.

保持炉７２からダイカスト機７ｌの金型のキャビティに
溶湯７６が圧入された。This molten metal 75 was distributed to the holding furnace 72, and then the molten metal 76 was press-fitted from the holding furnace 72 into the cavity of the mold of the die-casting machine 7l.

。The second method is to install a relatively small melting furnace 82 near the die-casting machine 8I as shown in FIG. The amount of molten metal 84 reduced due to the injection
This molten metal is then supplied to the mold.
（発明が解決しようとする問題点）
しかし、上記各方式には次のような問題点かあった。前
者はダイカスト機に対して保持炉及び溶解炉を分離して
稼動するので、この方式は溶潟の温度管理は比較的容易
であるが、一方配湯、注湯に多人の人力を必要とするも
のであり、そしてその作業場の立地としては広いスペー
スを必要とした。(Problems to be Solved by the Invention) However, each of the above systems has the following problems. In the former, the holding furnace and melting furnace are operated separately from the die-casting machine, so this method makes it relatively easy to control the temperature of the molten lagoon, but on the other hand, it requires the labor of many people to distribute and pour the molten metal. This required a large space for the workshop.
一方、後者は作業スペースを極力狭少に押さえた点は良

が設けられるので、環境温度が上昇して作業能率が著し
く低下した。On the other hand, the latter is good in that the work space is kept as small as possible, but like the former, it requires manpower, and in addition, as mentioned above, when the molten lagoon is reduced, billets at room temperature are directly fed into the small melting furnace. Since the molten metal is poured into a die-cast product, the temperature of the molten metal drops and fluctuates considerably each time it is fed, and the work tends to be intermittent, requiring complex control in order to continuously produce die-cast products of stable quality. In addition, since a melting furnace at a higher temperature than the holding furnace was installed in the vicinity of the die-casting machine, the environmental temperature rose and work efficiency was significantly reduced.
この発明は上記問題点に鑑み、省スペースで、かつ好適

る。In view of the above problems, this invention is an induction melting and holding device for die casting, which saves space, provides a suitable working environment, and can instantaneously supply molten metal at a constant temperature to the die of a die casting machine with less manpower. It is something that provides a lot of flavor.

抑制することができる。(Function) Material metals such as billets and ingots at room temperature are charged and heated by high-frequency induction heating during melting. This melting section applies a higher amount of heat to the material alloy by direct heating by induction compared to the melting section. Therefore, since the loss of heat released from the melting section is extremely small, the melting section can be provided directly connected to the die-casting machine or in the vicinity. The charging of billets, etc. is done on the large-diameter side of the melting section, and the removal of the melt field is performed on the small diameter side using a distribution plunger, which greatly suppresses fluctuations in the temperature of the molten metal due to charging of billets, etc. can do.
