Description

本発明は、アルミニウムまたはアルミニウム合金の溶湯を所定サイズのインゴット（鋳塊）に連続して鋳造する鋳造装置に関し、特に重量が１ｋｇ以下の小形塊の鋳造に適した鋳造装置に関する。   The present invention relates to a casting apparatus for continuously casting a molten aluminum or aluminum alloy into an ingot (ingot) of a predetermined size, and particularly to a casting apparatus suitable for casting a small ingot having a weight of 1 kg or less.

例えば、アルミニウムなどのダイカスト鋳造などに用いる多数のインゴットを連続して鋳造し、得られた多数のインゴットを冷却しつつ搬出するため、次述するようなインゴットの製造ラインが提案されている（例えば、特許文献１参照）。
係るインゴットの製造ラインは、ほぼ箱形を呈する多数の鋳型をエンドレスにして連結した成形コンベアと、係る成形コンベアの下方に沿って配置された受渡しコンベアと、係る受渡しコンベアの下方に配置され且つ一部が冷却水槽内を通過する冷却コンベアと、を備えている。
実開平５−３９７３８号公報 （第１〜１１頁、図１〜６） For example, in order to continuously cast a large number of ingots used for die casting of aluminum or the like and carry out the cooling of the large number of ingots obtained, an ingot production line as described below has been proposed (for example, , See Patent Document 1).
Such an ingot production line includes a molding conveyor in which a number of substantially box-shaped molds are connected in an endless manner, a delivery conveyor arranged along the lower side of the molding conveyor, and a lower part of the delivery conveyor. A cooling conveyor passing through the cooling water tank.
Japanese Utility Model Publication No. 5-39738 (pages 1 to 11 and FIGS. 1 to 6)

そして、前記成形コンベアにおける個々の鋳型に順次鋳込まれた多数のインゴットを確実に受け渡すため、下向きに開口する姿勢となった鋳型の裏面をハンマーで打設して強制的に受渡しコンベア上に落下させると共に、係るコンベアの端部に取り付けたインゴット押え部材と、これに隣接して配置した複数のローラとによって、上記インゴットの姿勢を上下逆転させることにより、多数のインゴットを前記冷却コンベアの係止爪上に順次受け渡させている。係る冷却コンベアの係止爪上に受け渡されたインゴットは、当該コンベアが前記冷却水槽を通過する際に、常温付近の温度にまで冷却される。   And in order to reliably deliver a large number of ingots sequentially cast into individual molds in the molding conveyor, the back surface of the mold, which is in a downward opening posture, is placed with a hammer to forcibly be placed on the delivery conveyor. The ingot holding member attached to the end portion of the conveyor and a plurality of rollers arranged adjacent to the ingot holding member are reversed upside down so that a large number of ingots are engaged with the cooling conveyor. It is handed over to the pawl sequentially. The ingot delivered onto the locking claws of the cooling conveyor is cooled to a temperature near room temperature when the conveyor passes through the cooling water tank.

しかしながら、前記特許文献１に開示されたインゴットの製造ラインは、成形コンベア、受渡しコンベア、および一部が冷却水槽内を通過する冷却コンベアを備えているため、設備自体が大型で複雑となり、且つ広いスペースを必要とする。更に、鋳型の裏面を打接する前記ハンマー、受渡しコンベアの端部に取り付けたインゴット押え部材、係る押え部材に隣接し且つ前記冷却コンベアの斜め上方に配置した複数の前記ローラ、および係る複数のローラの姿勢を変更する油圧シリンダなども必要である。このため、設備コストが嵩み、且つ複雑な操作に伴う運転を行わざるを得ないと共に、多大なメンテナンスも必要である。しかも、前記ハンマーによる生じる騒音により、作業環境も劣悪となる、などの問題があった。   However, since the ingot production line disclosed in Patent Document 1 includes a forming conveyor, a delivery conveyor, and a cooling conveyor that partially passes through the cooling water tank, the facility itself is large and complicated, and is wide. Requires space. Further, the hammer that contacts the back surface of the mold, an ingot holding member attached to an end of the delivery conveyor, a plurality of the rollers arranged adjacent to the holding member and obliquely above the cooling conveyor, and the plurality of rollers A hydraulic cylinder or the like that changes the posture is also necessary. For this reason, the equipment cost is high, and it is unavoidable to perform an operation associated with a complicated operation, and a large amount of maintenance is required. Moreover, there is a problem that the working environment is deteriorated due to the noise generated by the hammer.

一方、小形で単純な形状をした金属塊（インゴット）を多数連続的に鋳造し得るように自動化された連続鋳造機も提案されている（例えば、特許文献２参照）。
係る連続鋳造機は、水平回転する円形の基板の外周辺に沿って、複数の鋳型を丁番を介して枢支し、係る鋳型を下側から支持する車輪を円筒カムの上面に沿って転動可能とし、各鋳型内に注湯され且つ凝固した金属塊を有する鋳型が、上記円筒カムの一部に設けた低位置を通過する際、当該鋳型を上記丁番を回転中心として、外側向きに回転させることで、金属塊を外部に放出させるようにしている。
しかしながら、上記連続鋳造機も、前記基板、円筒カム、丁番付けされ且つ車輪を有する複数の鋳型、および鋳型に金属溶湯を注湯するための注湯ロートなどを必要とし、構造が複雑で且つ装置が大型になり、設備コストも嵩むと共に、故障し易く、メンテナンスも繁茂になり易くなる、という問題があった。
特開昭５３−５４１２６号公報（第１〜３頁、第１〜４図） On the other hand, an automated continuous casting machine has also been proposed which is capable of continuously casting a large number of small and simple metal ingots (for example, see Patent Document 2).
In such a continuous casting machine, a plurality of molds are pivotally supported through hinges along the outer periphery of a horizontally rotating circular substrate, and a wheel that supports the molds from below is rotated along the upper surface of a cylindrical cam. When a mold having a metal lump that has been poured and solidified in each mold passes through a low position provided in a part of the cylindrical cam, the mold is directed outward with the hinge as a rotation center. The metal lump is released to the outside by rotating it.
However, the continuous casting machine also requires the substrate, a cylindrical cam, a plurality of molds that are hinged and have wheels, a pouring funnel for pouring molten metal into the mold, etc., and has a complicated structure. There is a problem that the apparatus becomes large in size, the equipment cost increases, it is easy to break down, and maintenance is likely to be prosperous.
JP-A-53-54126 (pages 1 to 3, FIGS. 1 to 4)

本発明は、背景技術において説明した問題点を解決し、比較的コンパクトで且つ低コストにより製作できると共に、複数の鋳型ごとに鋳込まれたアルミニウムなどのインゴットを確実に当該鋳型から脱型できる鋳造装置を提供する、ことを課題とする。尚、本明細書においては、アルミニウムとアルミニウム合金とを含めて、これらを単に「アルミニウム」または「アルミニウムなど」と称する。   The present invention solves the problems described in the background art, is relatively compact and can be manufactured at a low cost, and ingots such as aluminum cast for each of a plurality of molds can be reliably removed from the mold. It is an object to provide an apparatus. In this specification, including aluminum and an aluminum alloy, these are simply referred to as “aluminum” or “aluminum”.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

本発明は、前記課題を解決するため、発明者らによる鋭意研究および試験の結果、円盤形状を呈し且つ水平方向に沿って回転する冷却可能な回転体の上面・下面を貫通する複数の鋳型にアルミニウムなどの溶湯を鋳込むと共に、当該回転体がある程度に回転して冷却された鋳型内から先に鋳込まれたインゴットを自重で順次落下させる、ことに着想して成されたものである。
即ち、本発明の鋳造装置（請求項１）は、アルミニウムまたはアルミニウム合金の溶湯をインゴットに連続的に鋳造する装置であって、軸方向が垂直である回転軸と、係る回転軸の周囲に位置し且つ当該回転軸と共に回転する円盤状の回転体と、係る回転体の上面と下面との間を貫通する複数の鋳型と、上記回転体の下面のうち、上記回転軸の付近から外周側に至る範囲で且つ係る下面の一部を覆う水冷手段と、上記回転体の上方に配置され且つ上記鋳型に注湯可能な注湯手段と、を含む、ことを特徴とする。 In order to solve the above-mentioned problems, the present invention is based on the results of diligent research and testing by the inventors, and presents a plurality of molds penetrating the upper and lower surfaces of a coolable rotating body that exhibits a disk shape and rotates along the horizontal direction. It was conceived to cast molten metal such as aluminum and to sequentially drop the ingot previously cast from the inside of the mold cooled by rotating the rotating body to some extent.
That is, the casting apparatus of the present invention (Claim 1) is an apparatus for continuously casting a molten aluminum or aluminum alloy on an ingot, and is positioned around a rotating shaft having a vertical axial direction and the rotating shaft. And a disk-shaped rotating body that rotates together with the rotating shaft, a plurality of molds that penetrate between the upper surface and the lower surface of the rotating body, and a lower surface of the rotating body from the vicinity of the rotating shaft to the outer peripheral side. It includes a water-cooling means that covers a part of the lower surface in a range and a pouring means that is disposed above the rotating body and can be poured into the mold.

これによれば、注湯手段から前記回転体の径方向に沿って位置する単数または複数の鋳型に注湯されたアルミニウムの溶湯は、係る鋳型の底面を形成する前記水冷手段によって、急速に冷却され当該水冷手段に接触する下面側から順次凝固すると共に、回転体の水平方向に沿った回転を受ける間に冷却されて鋳型の内面形状に倣ったインゴット（鋳塊）となる。係るインゴットは、当該鋳型が前記回転体の回転により、水冷手段に接する位置から離脱した際に、その凝固収縮および自重によって、上記鋳型から脱型し回転体の下方に落下する。このため、装置の構成が簡素で且つ全体をコンパクトにできると共に、比較的狭いスペースでも容易に設置できる。従って、設備コストを低減でき、且つ操作も簡単・容易に行えると共に、メンテナンスを最小限にでき、作業環境を静粛化することも可能となる。   According to this, the molten aluminum poured into the mold or molds located along the radial direction of the rotating body from the pouring means is rapidly cooled by the water cooling means forming the bottom surface of the mold. Then, it is solidified sequentially from the lower surface side in contact with the water cooling means, and is cooled while receiving the rotation along the horizontal direction of the rotating body to become an ingot (ingot) following the inner surface shape of the mold. The ingot is removed from the mold by the solidification contraction and its own weight and falls below the rotating body when the mold is detached from the position in contact with the water cooling means by the rotation of the rotating body. For this reason, the configuration of the apparatus is simple and the whole can be made compact, and can be easily installed even in a relatively narrow space. Therefore, the equipment cost can be reduced, the operation can be performed easily and easily, the maintenance can be minimized, and the working environment can be made quiet.

尚、本発明の鋳造装置により鋳造されるインゴットには、緩いテーパが付いた複数の側面を含む全体がほぼ三角柱、ほぼ四角柱、などの多角柱形状を呈するものに限らず、緩いテーパが付いた周面を含む全体がほぼ円柱形、ほぼ楕円柱形、あるいは、ほぼ長円柱形を呈する鋳塊が含まれる。係る鋳塊は、緩いテーパが付いた長短４つの側面を含む全体がほぼ直方体を呈する一般的な形状のインゴットよりも、比較的小さく、例えば通常のアルミニウム合金からなり、約１００〜数１００ｇと軽量で小さな小形塊も含まれる。
また、前記回転体は、熱伝導性が高い銅製やグラファイト製のほか、鋳鉄または鋳鋼などの鋳物製や、あるいは、これらの複数の成形体の組立物からなる。 Note that the ingot cast by the casting apparatus of the present invention is not limited to the one that has a plurality of side surfaces with loose taper, but has a generally tapered shape, such as a triangular prism, a substantially quadrangular prism, etc. An ingot having a substantially cylindrical shape, a substantially elliptical column shape, or a substantially long cylindrical shape is included. Such an ingot is relatively smaller than an ingot of a general shape that has a substantially rectangular parallelepiped shape including four sides that are long and short with a loose taper. For example, the ingot is made of a normal aluminum alloy and is light in weight of about 100 to several hundred grams. Small small chunks are also included.
The rotating body is made of copper or graphite having high thermal conductivity, cast iron or cast steel, or an assembly of a plurality of these molded bodies.

更に、前記回転体は、例えば、その外周面に固定したチェーン、これに噛み合うスプロケット、係るスプロケットを回転させるモータ（油圧モータを含む、以下にても同じ）の組み合わせ、または、回転体の外周面に固定した従動ギア、係るギアとに噛み合う駆動ギア、係るギアを回転させるモータの組み合わせにより回転される。あるいは、前記回転軸を回転させるギア列または２つのスプロケットと、これらを回転させるモータの組み合わせにより、回転体を回転しても良い。
また、前記水冷手段は、前記回転体の下面のうち、前記回転軸の付近から外周側に至る範囲で、且つ係る下面の円周方向の一部を覆うものである。
更に、前記注湯手段には、例えば、溶解炉から出湯したアルミニウムの溶湯を受け入れる耐火物からなる樋、および係る樋の先端側の底面に設けた単数または複数の出湯孔などからなる形態が挙げられる。
加えて、前記回転体の下側で且つ前記水冷手段のない位置には、落下するインゴットを受け入れる冷却水槽、あるいは、当該水槽を荷台上に載置した搬送台車を配置することが望ましい。 Further, the rotating body is, for example, a chain fixed to the outer peripheral surface thereof, a sprocket meshing with the chain, a combination of motors (including a hydraulic motor, the same applies below) for rotating the sprocket, or an outer peripheral surface of the rotating body. The gear is rotated by a combination of a driven gear fixed to the gear, a driving gear meshing with the gear, and a motor for rotating the gear. Or you may rotate a rotary body with the combination of the gear train or two sprockets which rotate the said rotating shaft, and the motor which rotates these.
Further, the water cooling means covers a part of the lower surface of the rotating body in the circumferential direction of the lower surface in the range from the vicinity of the rotating shaft to the outer peripheral side.
Further, the pouring means includes, for example, a form made of a refractory that receives a molten aluminum melted from a melting furnace, and one or a plurality of tapping holes provided on the bottom surface on the front end side of the slag. It is done.
In addition, it is desirable to dispose a cooling water tank that receives a falling ingot or a transport carriage that places the water tank on a cargo bed, at a position below the rotating body and without the water cooling means.

また、本発明には、前記複数の鋳型は、前記回転体の下面に向かって広がるテーパが付いた形状を呈し、上記回転体の上面に開口する鋳口と、これよりも広い面積で回転体の下面に開口する落下口と、を備えている、鋳造装置（請求項２）も含まれる。
これによれば、各鋳型に注湯されたアルミニウムの溶湯は、落下口側の下面が広く且つ鋳口寄りの上面が狭くなるテーパが付されたインゴットになるので、前記水冷手段から離れた位置に当該鋳型が回転体と共に移動した際に、凝固収縮に伴って、鋳型から容易に脱型および落下し易くすることが可能となる。
更に、本発明には、前記鋳型は、前記鋳口の上部に、係る鋳口よりも広く開口する注湯口を有している、鋳造装置（請求項３）も含まれる。
これによれば、各鋳型の注湯口からアルミニウムの溶湯を注下する際に、その注湯量を当該鋳型の体積よりも小さい体積、即ち、係る溶湯のレベル（湯面）を前記鋳口と同じか、これよりも下側になるようにすることで、凝固収縮を伴って得られるインゴットを当該鋳型から容易に脱型および落下させられる。上記アルミニウムの溶湯量（体積）は、鋳込まれる鋳型の体積の約６０〜９０％である。
尚、各鋳型の内面には、酸化チタンなどの一般的な離型剤が塗布される。 Further, according to the present invention, the plurality of molds have a shape with a taper that spreads toward the lower surface of the rotating body, a casting hole that opens on the upper surface of the rotating body, and a rotating body having a wider area than this. A casting apparatus (Claim 2) is also included.
According to this, since the molten aluminum poured into each mold becomes a tapered ingot having a wide lower surface on the dropping port side and a narrow upper surface near the casting port, the position is away from the water cooling means. In addition, when the mold moves together with the rotating body, it can be easily removed from the mold and easily dropped along with the solidification shrinkage.
Furthermore, the present invention also includes a casting apparatus (Claim 3) in which the mold has a pouring hole that opens wider than the casting hole at the upper part of the casting hole.
According to this, when pouring the molten aluminum from the pouring spout of each mold, the pouring amount is smaller than the volume of the casting mold, that is, the level of the molten metal (melt surface) is the same as that of the casting spout. Alternatively, by making it lower than this, the ingot obtained with coagulation shrinkage can be easily removed from the mold and dropped. The amount of molten aluminum (volume) is about 60 to 90% of the volume of the casting mold.
A general mold release agent such as titanium oxide is applied to the inner surface of each mold.

また、本発明には、前記複数の鋳型は、平面視で前記回転体のほぼ全面に且つほぼ等間隔で配置されている、鋳造装置（請求項４）も含まれる。
これによれば、前記注湯手段に設けられ且つ回転体の半径方向に沿った複数の出湯孔からアルミニウムの溶湯を分流して注下することにより、比較的小さな体積の小形塊を同時に複数個ずつ鋳造することができる。あるいは、回転体の半径方向に沿って単数で且つ円周方向に沿って複数の鋳型を設けた形態では、注湯手段の単数または複数の出湯孔から溶湯を注下することで、全体がほぼ直方体を呈する一般的な形状のインゴットを連続的に鋳造することが可能となる。
尚、前記複数の鋳型は、少なくとも、回転体の円周方向に沿って配置された形態としても良い。 The present invention also includes a casting apparatus (Claim 4) in which the plurality of molds are disposed on substantially the entire surface of the rotating body in a plan view and at substantially equal intervals.
According to this, a plurality of small ingots having a relatively small volume are simultaneously provided by diverting and pouring the molten aluminum from a plurality of outlet holes provided in the pouring means and along the radial direction of the rotating body. Can be cast one by one. Alternatively, in the embodiment in which a single mold is provided along the radial direction of the rotating body and a plurality of molds are provided along the circumferential direction, the whole of the molten metal is poured substantially from the single or plural outlet holes of the pouring means. It becomes possible to continuously cast an ingot having a general shape that has a rectangular parallelepiped shape.
The plurality of molds may be arranged at least along the circumferential direction of the rotating body.

更に、本発明には、前記水冷手段は、前記回転体の下面に面接触可能な天板を含む水冷タンクと、係る水冷タンクに冷却水を給水および排水する給水管および排水管と、を含む、鋳造装置（請求項５）も含まれる。
これによれば、アルミニウムの溶湯は、各鋳型に注下された直後から、当該鋳型の落下口を閉塞する水冷タンクの天板に接触して、急速に冷却されつつ凝固し始めた後、係る凝固に伴う収縮を生じるので、係る鋳型の内面に倣った形状のインゴットにすることができる。
尚、前記水冷タンクは、平面視でほぼ扇形を呈する。係る水冷タンクのうち、少なくとも回転体の下面に面接触する天板は、少なくともその表層を、耐磨耗性および耐熱性の材料（例えば、超硬、セラミック、炭素繊維層など）により形成され、その上に前記同様の離型剤が塗布される。 Furthermore, in the present invention, the water cooling means includes a water cooling tank including a top plate that can come into surface contact with the lower surface of the rotating body, and a water supply pipe and a drain pipe for supplying and discharging cooling water to and from the water cooling tank. A casting apparatus (Claim 5) is also included.
According to this, immediately after being poured into each mold, the molten aluminum comes into contact with the top plate of the water-cooled tank that closes the dropping port of the mold and begins to solidify while being rapidly cooled. Since shrinkage occurs due to solidification, an ingot having a shape that follows the inner surface of the mold can be obtained.
The water-cooled tank has a substantially fan shape in plan view. Among such water-cooled tanks, at least the top plate that is in surface contact with the lower surface of the rotating body is formed of at least a surface layer of a wear-resistant and heat-resistant material (for example, carbide, ceramic, carbon fiber layer, etc.) A release agent similar to that described above is applied thereon.

加えて、本発明には、前記回転体の内部には、前記回転軸に内蔵された給水路および排水路と連通する冷却水の循環流路が形成されている、鋳造装置（請求項６）も含まれる。
これによれば、前記水冷手段の水冷タンクによる各鋳型の落下口側の冷却に加えて、各鋳型の周囲に形成された循環流路を冷却水が冷却することで、各鋳型に注下されたアルミニウムの溶湯を、注湯口側を除く鋳型のほぼ内面全体で、急速に冷却できる。このため、一層迅速に上記溶湯を凝固および収縮させたインゴットにすることができる。しかも、前記水冷手段の水冷タンクが、回転体の下面にに面接触する面積を小さくできるため、当該水冷タンクの小型化も可能となる。
尚、回転体の内部に形成される冷却水の循環流路は、隣接する鋳型同士の間隔がある程度以上である部分には、可能な限り配置することが望ましい。 In addition, according to the present invention, a casting device (Claim 6) in which a circulation channel for cooling water communicating with a water supply channel and a drain channel built in the rotation shaft is formed inside the rotating body. Is also included.
According to this, in addition to cooling the casting mold side of each mold by the water cooling tank of the water cooling means, the cooling water cools the circulation flow path formed around each mold, so that the cooling water is poured into each mold. The molten aluminum can be rapidly cooled over almost the entire inner surface of the mold except the pouring side. For this reason, it can be made into the ingot which solidified and contracted the said molten metal more rapidly. In addition, since the area of the water cooling tank of the water cooling means that is in surface contact with the lower surface of the rotating body can be reduced, the water cooling tank can be downsized.
In addition, it is desirable to arrange | position the circulating flow path of the cooling water formed inside a rotary body as much as possible in the part where the space | interval of adjacent casting_mold | templates is a certain amount or more.

In addition, a drain pipe 17 of the cooling water w communicating with the drain path 15 in the rotating body 4 is connected to the central portion of the upper shaft 2a of the rotating shaft 2 through a universal joint uj. The water supply pipe 16 passes through a hole h opened in the side wall of the support 18.
As shown on the right side of FIGS. 2 and 3, below the rotating body 4, water cooling means 20 including a water cooling tank 21 having a substantially fan shape in plan view is arranged. The top plate 22 of the water-cooled tank 21 is in surface contact with the lower surface 6 while covering a part in the circumferential direction on the lower surface 6 of the rotating body 4 from the vicinity of the lower shaft 2b of the rotating shaft 2 to the outer peripheral side. And is slidable. The same release agent as that described above is also applied to the top plate 22. A water supply pipe 23 and a drain pipe 24 for the cooling water w communicate with the bottom surface of the water cooling tank 21.

更に、図２，図３の左側に示すように、回転体４の下方で且つフロアＦ上には、平面視がほぼ扇形を呈する水槽２５が、図示しない台座を介して配置されている。
加えて、図２，図３の右上側に示すように、回転体４の上方には、係る回転体４の半径方向に沿った複数の鋳型ｃに、アルミニウムの溶湯ｍをほぼ同時に注湯するための注湯手段２６が配置されている。係る注湯手段２６は、図示しない溶解炉から出湯されたアルミニウムの溶湯ｍを流入させる耐火性の樋２７、その先端部の底面に開設された複数の出湯口２８、および係る出湯口２８を内設して樋２７の底面から垂下する複数の出湯管２９を備えている。 Further, as shown on the left side of FIGS. 2 and 3, a water tank 25 having a substantially fan shape in plan view is disposed below the rotating body 4 and on the floor F via a pedestal (not shown).
In addition, as shown in the upper right side of FIGS. 2 and 3, above the rotating body 4, molten aluminum m is poured almost simultaneously into a plurality of molds c along the radial direction of the rotating body 4. A pouring means 26 is provided for this purpose. The pouring means 26 includes a refractory rod 27 into which molten aluminum m discharged from a melting furnace (not shown) flows, a plurality of outlets 28 opened at the bottom of the tip, and the outlet 28. A plurality of hot water discharge pipes 29 that are provided and hang down from the bottom surface of the bowl 27 are provided.

ここで、前記鋳造装置１の操業（使用）方法について、説明する。
予め、回転体４の各鋳型ｃの内面と、水冷タンク２１の天板２２とに対し、酸化チタン系の離型剤を塗布し、前記モータＭを駆動して、回転軸２と共に回転体４を水平方向に沿って、約１ｒｐｍの緩やかな速度で回転させる。また、給水管１６から冷却水ｗを回転体４内部の給水路１３、各循環流路１４、排水路１５、および排水管１７の順序で循環させると共に、水冷手段２０の水冷タンク２１内にも、給水管２３および排水管２４を介して、冷却水ｗを循環させる。
尚、上記排水管１７，２４から排水される比較的温かい水は、図示しない冷却水槽または熱交換器を経て再度冷却され、上記冷却水ｗとして循環される。
更に、図３，図４に示すように、注湯手段２６における樋２７の先端側に位置するを出湯管２９に内設される複数の出湯口２８を、回転体４の半径方向に沿った複数の鋳型ｃの各注湯口７のほぼ真上に配置させる。 Here, an operation (use) method of the casting apparatus 1 will be described.
In advance, a titanium oxide release agent is applied to the inner surface of each mold c of the rotating body 4 and the top plate 22 of the water cooling tank 21, and the motor M is driven to rotate the rotating body 4 together with the rotating shaft 2. Is rotated along the horizontal direction at a gentle speed of about 1 rpm. Further, the cooling water w is circulated from the water supply pipe 16 in the order of the water supply path 13, each circulation flow path 14, the drainage path 15, and the drainage pipe 17 in the rotating body 4, and also in the water cooling tank 21 of the water cooling means 20. The cooling water w is circulated through the water supply pipe 23 and the drain pipe 24.
The relatively warm water drained from the drain pipes 17 and 24 is cooled again through a cooling water tank or a heat exchanger (not shown) and circulated as the cooling water w.
Further, as shown in FIGS. 3 and 4, a plurality of hot water outlets 28 provided in the hot water outlet pipe 29, which are located on the distal end side of the tub 27 in the pouring means 26, are arranged along the radial direction of the rotating body 4. It arrange | positions just above each pouring spout 7 of the some casting_mold | template c.

次いで、図４，図６に示すように、注湯手段２６の樋２７に送られたアルミニウムの溶湯ｍを、複数の出湯管２９内の出湯口２８ごとから、真下に位置する回転体４における落下口８が水冷タンク２１の天板２２で塞がれた複数の鋳型ｃ内に向けて注湯する。この際、各鋳型ｃ内に注湯される溶湯ｍの体積は、その湯面が鋳型ｃ内の鋳口９と同じレベルか、それよりも下側となるようにされる。因みに、各鋳型ｃの内容積のうち、鋳口９から落下口８に至る下部側は、その約６０〜９０％を占めている。
尚、回転体４は、回転軸２から離れるほど鋳型ｃの回転速度が速くなるので、回転軸２付近の鋳型ｃに注湯する出湯口２８の内径を小さくし、出湯速度を遅くする等して、各鋳型ｃに注湯される溶湯ｍの量を等しくなるようにすることが好ましい。また、隣接する鋳型ｃ，ｃ間には、注湯された溶湯ｍが最接近する鋳型ｃに速やかに流れ込むように、図示しない凸条を上面５に突設することが好ましい。 Next, as shown in FIG. 4 and FIG. 6, the molten aluminum m sent to the gutter 27 of the pouring means 26 is fed to the rotary body 4 located directly below from the outlets 28 in the plurality of outlet pipes 29. The dropping port 8 is poured into a plurality of molds c closed by the top plate 22 of the water cooling tank 21. At this time, the volume of the molten metal m poured into each mold c is set so that the molten metal surface is at the same level as or lower than the casting hole 9 in the mold c. Incidentally, the lower side from the casting port 9 to the dropping port 8 occupies about 60 to 90% of the internal volume of each mold c.
In addition, since the rotational speed of the casting_mold | template c becomes quick, so that the rotary body 4 leaves | separates from the rotating shaft 2, the internal diameter of the hot water outlet 28 poured into the casting mold c near the rotating shaft 2 is made small, and the hot water speed is made slow. Thus, it is preferable to make the amount of the molten metal m poured into each mold c equal. In addition, it is preferable that a protrusion (not shown) protrudes from the upper surface 5 between the adjacent molds c and c so that the poured molten metal m quickly flows into the closest mold c.

各鋳型ｃ内に注下されたアルミニウムの溶湯ｍは、当該鋳型ｃの落下口８を閉塞する水冷タンク２１および周囲に位置する循環流路１４内を流動する冷却水ｗにより、鋳型ｃの内面に接する外周側から急速に冷却され、求心状に凝固し始める。その結果、鋳口９よりも下側の内部形状に倣ったほぼ四角柱体で且つ各側面に緩いテーパが付いたインゴット（小形塊）Ｃとなる。この間において、回転体４の水平回転に伴って、各鋳型ｃ内に注湯された溶湯ｍは、上記インゴットＣになりつつ、水冷タンク２１の天板２２上を回転体４の円周方向に沿って移動して行く。   The molten aluminum m poured into each mold c is converted into an inner surface of the mold c by the cooling water w flowing in the water cooling tank 21 and the circulation channel 14 located around the water cooling tank 21 that closes the dropping port 8 of the mold c. It is rapidly cooled from the outer peripheral side in contact with and begins to solidify centripetally. As a result, an ingot (small ingot) C is obtained which is a substantially quadrangular prism body that follows the internal shape below the casting port 9 and has a loose taper on each side surface. During this time, the molten metal m poured into each mold c with the horizontal rotation of the rotator 4 becomes the ingot C, and on the top plate 22 of the water-cooled tank 21 in the circumferential direction of the rotator 4. Go along.

更に、前記各インゴットＣは、注湯された当初の位置から回転体４が約半周程度水平回転する間に、その凝固に伴う収縮によって、各鋳型ｃの内面から離脱し始め、図５，図６に示すように、水冷タンク２０の天板２２から離れ、且つ水ｗが張られた前記水槽２５の上方に到達した際に、各鋳型ｃの落下口８から、水槽２５内の水ｗ中に向かって、ほぼ同時に、またはややずれたタイミングにて、自重により落下する。係るインゴットＣは、図５の右下に例示するように、各側に緩いテーパが付いたほぼ四角柱形状を呈する。これらのインゴットＣが落下した各鋳型ｃは、図６に示すように、回転体４の回転に伴って、再び前記水冷タンク２１の上方に復帰し、前記同様にしてアルミニウムの溶湯ｍが注湯される。
以上のような溶湯ｍの注湯、凝固、インゴットＣの落下は、回転体４が水平回転を１回転ずつ行うたびに、確実に行われ、多数のインゴットＣを連続して効率良く鋳造することができる。 Further, each ingot C starts to be detached from the inner surface of each mold c due to contraction accompanying solidification while the rotating body 4 horizontally rotates about half a circumference from the initial position where the molten metal is poured, and FIG. 6, when the water w is separated from the top plate 22 of the water cooling tank 20 and reaches the upper side of the water tank 25 where the water w is stretched, Towards the head, it falls by its own weight at almost the same time or at a slightly shifted timing. The ingot C has a substantially quadrangular prism shape with a loose taper on each side, as illustrated in the lower right of FIG. As shown in FIG. 6, the molds c in which the ingots C dropped are returned to the upper side of the water cooling tank 21 as the rotating body 4 rotates, and the molten aluminum m is poured as described above. Is done.
The above-described pouring, solidification, and dropping of the ingot C of the molten metal m are surely performed every time the rotating body 4 performs horizontal rotation one by one, and many ingots C are continuously and efficiently cast. Can do.

前記のような鋳造装置１によれば、注湯手段２６から前記回転体４の径方向に沿って位置する複数の鋳型ｃに注湯されたアルミニウムの溶湯ｍは、各鋳型ｃを囲む循環流路１４内の冷却水ｗおよびその底面に接する前記水冷タンク２１内の冷却水ｗによって、急速に冷却され各鋳型ｃの内面に接する外周側から順次凝固して行く。平行して、回転体４の水平方向に沿った回転する間に、鋳型ｃの内面形状に倣ったインゴットＣとなる。係るインゴットＣは、鋳型ｃが回転体４の回転によって、水冷手段２０の水冷タンク２１から離脱した際に、その凝固収縮および自重によって、各鋳型ｃから脱型し回転体４の下方に落下する。このため、装置の構成が簡素で且つ全体をコンパクトにできると共に、比較的狭いスペースでも容易に設置できる。従って、設備コストを低減でき、且つ操作も簡単・容易に行えると共に、メンテナンスを最小限にでき、作業環境も静粛化が可能となる。   According to the casting apparatus 1 as described above, the molten aluminum m poured into the plurality of molds c positioned along the radial direction of the rotating body 4 from the pouring means 26 is circulated around each mold c. The cooling water w in the passage 14 and the cooling water w in the water cooling tank 21 in contact with the bottom surface thereof are rapidly cooled and solidified sequentially from the outer peripheral side in contact with the inner surface of each mold c. In parallel, the ingot C follows the shape of the inner surface of the mold c while rotating along the horizontal direction of the rotating body 4. When the mold c is detached from the water cooling tank 21 of the water cooling means 20 by the rotation of the rotating body 4, the ingot C is demolded from each mold c and falls below the rotating body 4 due to its solidification contraction and its own weight. . For this reason, the configuration of the apparatus is simple and the whole can be made compact, and can be easily installed even in a relatively narrow space. Therefore, the equipment cost can be reduced, the operation can be performed easily and easily, the maintenance can be minimized, and the working environment can be made quiet.
