The invention makes it possible to manufacture high-quality cast parts in a particularly productive manner. According to the inventive method, a casting mould with a filling opening (2) pointing in the direction of gravity (S) is provided during the casting of the molten metal (A), particularly molten aluminium; the casting mould (1) with the filling opening (2) is coupled to a melt container (12) containing the molten metal (A); the molten metal (A) is conveyed from the melt container (12) into the casting mould (1) counter to the direction of gravity; the casting mould (1) is sealed directly after filling with molten metal (A) by means of a locking device (6) which is at least temporarily connected to the casting mould (1) in a fixed manner; the casting mould (1) is decoupled from the melt container (12) directly after closure of the casting mould (1) and the casting mould (1) is rotated about a horizontal axis of rotation (X), wherein the casting mould (1) remains in a sealed position with respect to the locking device (6) which is firmly connected thereto during rotation. The invention also relates to a correspondingly embodied device. .

En vue d'obtenir une production particulièrement rentable de pièces moulées de haute qualité, l'invention est caractérisée en ce qu'on prépare, lors de la coulée du métal en fusion (A), en particulier de l'aluminium en fusion, une ouverture de remplissage (2) orientée en direction de la pesanteur (S), en ce que le moule de coulée (1), avec l'ouverture de remplissage (2), est accouplé à un conteneur de fusion (12) renfermant le métal fondu (A), en ce que le métal fondu (A) est déversé dudit conteneur (12), dans le moule de coulée (1), à l'encontre de la direction de la pesanteur, en ce que le moule de coulée (1) est fermé, immédiatement après remplissage du métal fondu (A), au moyen d'un dispositif d'obturation (6) qui est lié, au moins temporairement, de manière fixe avec le moule de coulée (1), en ce que le moule de coulée (1) est désaccouplé du conteneur de fusion (12), immédiatement après fermeture dudit moule de coulée, et en ce que le moule de coulée (1) tourne autour d'un axe de rotation horizontal (X), ledit moule de coulée (1) demeurant en position scellé par rapport au dispositif d'obturation (6) lié de manière fixe à celui-ci. L'invention concerne en outre un dispositif réalisé de façon correspondante.
