Device for shooting a foundry core

A device for shooting a foundry core, which surrounds a free inner space on its outer boundaries, wherein the device has 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, wherein a clear width of the mould cavity is determined by a distance of an inner surface, assigned to the mould cavity, of the outer slider to an outer surface of the inner slider, wherein the inner slider is divided into at least three inner slider segments along dividing planes, which extend in a longitudinal direction of the inner slider and wherein the inner slider segments are displaceable between a removal position, in which they are positioned approximated in relation to one another and to the longitudinal axis of the inner slider and the clear width of the mould cavity present between the inner slider and the outer slider is increased, into a shooting position approximating the outer slider, in which the clear with of the mould cavity corresponds to a target specification for the foundry core to be shot, characterised in that one of the inner slider segments is movable in a radial direction on the longitudinal axis of the inner slider into a receiving portion, which is laterally delimited by in each case one further slider segment and expands in the direction of the longitudinal axis of the inner slider in the case of the slider segments being in the shooting position.
