【考案の詳細な説明】
（産業上の利用分野）
本考案は鋳造用の砂鋳型を造型保持する鋳枠に
関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a casting flask for forming and holding a sand mold for casting.
（従来技術）
一般に水平割鋳型を上方に積み重ねた鋳型に溶
湯を注入して鋳造を行う場合、溶湯浮力により鋳
型が浮き上がらないように重錘を最上段の鋳型上
に載せるのが普通であり、この重錘は溶湯浮力に
応じた重量のものが使用される。(Prior art) Generally, when casting is performed by pouring molten metal into a mold in which horizontally split molds are stacked upwards, a weight is usually placed on the top mold to prevent the mold from floating due to the buoyancy of the molten metal. This weight has a weight that corresponds to the buoyancy of the molten metal.
一方最近では、水平割鋳型を２段に積み重ねて
この鋳型に注湯を行う一般的な鋳造方式の他に鋳
型を３段に重ねて注湯を行う鋳造方式も採用され
るようになつており、重ねられる鋳型の段数に応
じて溶湯浮力も異なることになりそれに応じた重
錘が用意されるのが普通である。 On the other hand, recently, in addition to the general casting method in which horizontally split molds are stacked in two tiers and metal is poured into the molds, a casting method in which the molds are stacked in three tiers and poured into the molds has also been adopted. Since the buoyancy of the molten metal differs depending on the number of stacked molds, a weight is usually prepared accordingly.
しかし重い重錘を鋳型の上面に載せた場合、鋳
型の合せ面に大きな面圧力を発生させる事になり
鋳型の損傷を起し鋳造品に不良を発生させる原因
となる。 However, if a heavy weight is placed on the top of the mold, a large surface pressure will be generated on the mating surfaces of the mold, causing damage to the mold and causing defects in the cast product.
（考案の目的）
本考案は、このような現状に鑑みて開発された
ものであつて鋳型を３段以上に積み重ねて注湯を
行う場合に好適な鋳枠を提供することを目的とし
て完成されたものである。(Purpose of the invention) The present invention was developed in view of the current situation, and was completed with the aim of providing a casting flask suitable for pouring metal by stacking molds in three or more tiers. It is something that
（考案の構成）
以下本考案の構成を第１図に基づき説明すると
１は平面矩形状の壁部２の外周側に突出肉厚部３
を均厚にして１体的に設けた鋳枠である。(Structure of the invention) The structure of the invention will be explained below based on FIG.
This is a casting flask that has a uniform thickness and is installed in one piece.
（考案の作用）
上記のように構成された鋳枠１は次のように使
用される。(Operation of the invention) The flask 1 constructed as described above is used as follows.
すなわち、定盤４の上部に鋳型５内蔵の下鋳枠
６を載置し該下鋳枠６の上部に鋳型７内蔵の本考
案鋳枠１を載置し、さらに該鋳枠１の上部に鋳型
８内蔵の上鋳枠９を載置し、該鋳型８の上部に重
錘１０を載置する。 That is, a lower flask 6 with a built-in mold 5 is placed on top of the surface plate 4, a flask 1 of the present invention with a built-in mold 7 is placed on top of the lower flask 6, and An upper flask 9 with a built-in mold 8 is placed, and a weight 10 is placed on top of the mold 8.
尚、前記鋳枠１の突出肉厚部３の重量は壁部２
の重量と合せて鋳型５，７で構成されるキヤビテ
イ１１に注入される溶湯浮力に対応する重量にさ
れ、また重錘１０の重量は鋳型７，８で構成され
るキヤビテイ１２に注入される溶湯浮力に対応す
る重量にされている。 Note that the weight of the protruding thick wall portion 3 of the flask 1 is greater than the weight of the wall portion 2.
The weight of the weight 10 is set to correspond to the buoyancy of the molten metal poured into the cavity 11 made up of the molds 5 and 7, and the weight of the weight 10 is set to correspond to the buoyancy of the molten metal poured into the cavity 12 made up of the molds 7 and 8. The weight is adjusted to accommodate buoyancy.
このように３段重ね鋳型を構成させれば注湯時
の鋳型７および鋳枠１の浮き上がりは鋳枠１自身
の重量により阻止され、さらに鋳型８および上鋳
枠９の浮き上がりは重錘１０により阻止される。
しかも鋳型５，７、および鋳型７，８の合せ面に
加えられる面圧力はそれぞれ最小限となる。 By configuring the three-tiered mold in this way, the lifting of the mold 7 and the flask 1 during pouring is prevented by the weight of the flask 1 itself, and furthermore, the lifting of the mold 8 and the upper flask 9 is prevented by the weight 10. blocked.
Moreover, the surface pressures applied to the molds 5, 7 and the mating surfaces of the molds 7, 8 are respectively minimized.
（考案の効果）
以上の説明によつて明らかなように本考案の鋳
枠を３段重ね鋳型による鋳造を使用すれば各鋳型
の合せ面に加えられる面圧力を最小限にとどめな
がら各鋳型の浮き上がりを確実に防止することが
可能であり、この種の業界に寄与する効果は著大
である。(Effects of the invention) As is clear from the above explanation, if the casting flask of the invention is used for casting using three stacked molds, the surface pressure applied to the mating surfaces of each mold can be kept to a minimum while It is possible to reliably prevent floating, and the effect of contributing to this type of industry is significant.
