鉛等の金属溶湯を鋳型または鋳型用もしくはダイカスト
用スリーブ等に注ぐために使用される金属溶湯用注湯装
置に関する。[Detailed Description of the Invention] (Field of Industrial Application) This invention is a molten metal used for pouring a molten metal such as aluminum, brass, or zinc supplied from a furnace into a mold or a sleeve for a mold or a die casting. Related to pouring equipment.
（従来の技術） 例えば、従来、アルミニウムの鋳造工程において、アル
ミニウムの溶湯を炉から成形用の鋳型やスリーブ等の所
定部位に供給するに際しては、炉から一定容量のラドル
によって溶湯を汲み上げ、これを鋳型やスリーブの注湯
口まで運んで注湯を行うのが一般的である。(Prior Art) For example, in the past, in the process of casting aluminum, when supplying molten aluminum from a furnace to a predetermined site such as a molding mold or sleeve, the molten metal was pumped up from a furnace with a ladle of a certain volume. It is common to carry it to the pouring port of a mold or a sleeve for pouring.
この従来方法にあっては、しかしながら、炉から溶湯を
汲み上げる際に溶湯表面に浮かんでいるノロと呼ばれる
不純物も一緒に汲み上げて注湯してしまう欠点があっ
た。However, this conventional method has a drawback in that when the molten metal is pumped from the furnace, impurities called “Noro” floating on the surface of the molten metal are also pumped and poured.
また、添付図面の第４図に図示したように、注湯は注湯
口50でラドル40を矢印方向に傾動して行われるのである
が、一定速度でラドルを傾動してもラドル形状によって
傾動角度と流出量が一定にならず従って定量かつ静流状
態での溶湯の供給ができず、さらに、ラドル内に残った
溶湯が金属酸化皮膜となって付着し次回の注湯時に混入
してしまうなどの問題があった。Further, as shown in FIG. 4 of the accompanying drawings, pouring is performed by tilting the ladle 40 in the direction of the arrow at the pouring port 50. However, even if the ladle is tilted at a constant speed, the tilt angle depends on the ladle shape. Therefore, the molten metal cannot be supplied in a constant and static flow state, and the molten metal remaining in the ladle adheres as a metal oxide film and mixes in at the next pouring. There was a problem.
また、ラドルが炉から鋳型やスリーブの注湯口まで移動
するまでに、ラドル内の溶湯がこぼれて作業場を汚した
り、溶湯の温度が降下したりする等の問題も生じてい
る。Further, before the ladle moves from the furnace to the pouring port of the mold or the sleeve, the molten metal in the ladle spills and pollutes the work place, and the temperature of the molten metal drops.

る。(Problems to be solved by the invention) Therefore, in view of the above situation, this invention is a pouring device for a molten metal capable of supplying a clean molten metal to a pouring port of a mold or a sleeve in a constant outflow amount. The purpose is to provide. At the same time, the present invention provides a pouring device for molten metal, in which the molten metal does not spill when the molten metal is moved and the work place is polluted or the temperature of the molten metal drops.

In addition, since the injection portion for introducing the molten metal into the pipe body is formed at a position higher than the molten metal overflow position in the outflow portion at the rear upper end of the pipe body, the molten metal is formed by the so-called communication pipe principle. It flows out in an overflow state from the outflow part. Therefore, according to the device of the present invention, if the hot water supply from the inlet is constant, the pouring from the outflow portion can always be performed by a static flow at a constant flow rate, and the disturbance of the molten metal in the conventional pouring process can be performed. The flow can be prevented. This also means that the pouring conditions can be made constant at the same time, and the pouring conditions can be easily set.
