Abstract: The present invention relates to a device for shooting a foundry core which surrounds a free inner space on its outer boundaries, with the device having a mould cavity representing the foundry core, which circulates around an inner slider extending along a longitudinal axis and is delimited on its outer side by an outer slider circulating around the mould cavity, with the clear width of the mould cavity being determined by the distance of the inner surface of the outer slider, assigned to the mould cavity, to the outer surface of the inner slider. The device according to the invention allows for operationally-safe manufacture of foundry cores that are tubular in their base form, but finely-structured in their walls and also on a large scale.

Abstract: The invention relates to a core box for manufacturing casting cores from a moulding material rigidified by supply of heat, including at least two core box parts, which together provide the shape of the casting cores to be manufactured and a heating device for heating the core box parts. The heating device has at least one oil line in thermal contact with at least one of the core box parts and connected to an oil supply feeding the oil line with a tempered oil for heating the core box parts. The invention divides at least one of the core box parts into a contour plate, providing the shape of the casting cores to be manufactured, and a heating plate connected to the contour plate, said heating plate extending flat over the contour plate and in which the oil line is provided.
