次に、図16及び図17を参照して、第3実施形態に係る鋳造設備について説明する。図16は、第3実施形態に係る鋳造設備の一部構成の側面図である。図17は、図16に示すフォークの平面図である。
図18は、第4実施形態に係る鋳造装置の概要構成正面図である。図18に示されるように、第4実施形態に係る鋳造装置50Aは、主に、下金型2を昇降する型閉機構21が下部フレーム6に設けられるとともに、押出しシリンダ30が上部フレーム5に設けられる点で、第1実施形態に係る鋳造装置50と相違している。これにより、鋳造装置50Aでは、下金型2が昇降可能とされている。
図19は、第5実施形態に係る鋳造装置について説明する図である。ここでは、説明理解の容易性を考慮し、上金型1の内面1s及び下金型2の内面2sは、仮想的な形状で示されている。図19の(a)に示されるラドル25は、下金型2に対して水平に取り付けられている。これに対して、図19の(b)に示されるように、第5実施形態に係る鋳造装置に係るラドル25は、上金型1と下金型2とが傾動する傾動方向に傾けた状態で下金型2に取り付けられている。傾動方向とは、ラドル25内の溶湯が上金型1及び下金型2内に傾動注湯される際に、上金型1及び下金型2が傾動する方向である。ここでは、左回転する方向である。即ち、ラドル25の注湯口25aと下金型2の受湯口2aとの接続部分を中心に、ラドル25を左回転する方向である。ラドル25を図19の(a)の状態から図19の(b)の状態に至るまで左回転させたときの回転角度が、ラドル25の下金型2に対する取付角度に対応する。ラドル25の取付角度は、例えば5°~30°の範囲で方案に応じた適切な角度に設定される。
