意匠に係る物品は、鋳物製造用構造体である。本物品は、鋳物を製造する際に、内部に溶融金属が流れる湯道管の一部として用いられる。例えば、本物品を複数連結することによって形成された湯道管を砂型内に埋設した後、該湯道管の一端に設けられた注湯口から溶融金属を注ぎ入れ、該砂型のキャビティ内に溶融金属を供給し、鋳造を行う。The design article is a structure for casting. The article is used as part of a runner through which molten metal flows in the production of castings. For example, after embedding a runner pipe formed by connecting a plurality of the articles in a sand mold, molten metal is poured from a pouring port provided at one end of the runner pipe, and melted in the cavity of the sand mold. Supply metals and carry out castings.
