Abstract
【解決手段】鋳造装置は、下方に開口を有するキャビティを形成する金型と、金型の下方に配置されて溶湯を収容すると共に溶湯の上部に密閉空間を形成する加圧室と、上端開口がキャビティの開口に連通し下端開口が加圧室内の溶湯の内部に浸漬された筒状のストークと、加圧室の密閉空間にガスを供給して加圧室内を加圧する加圧手段と、キャビティからガスを排出してキャビティ内を減圧する減圧手段と、制御装置とを有する。制御装置は、加圧室からキャビティに溶湯を充填する際、溶湯がキャビティの開口に達するまで加圧手段によって加圧室内を加圧し、溶湯がキャビティの開口に達した後に加圧室内の加圧を続行しつつ、減圧手段によってキャビティ内を減圧する。
