<p>The machine comprises a housing, a casting mould rotatably mounted in the housing and a device for axially placing and maintaining a core against the end of the mould. The device comprises an element for urging the core against the mould, a releasable mechanism for fixing the core to the element and means for shifting the element between a position in which it urges the core against the mould and a withdrawn position. According to the invention, the mechanism is movable on the housing between a position in which it fixes the core to the element when the latter applies the core against the mould and a withdrawn position, the arrangement being such that the mechanism can follow, between its withdrawn position and its other position, the movement of the means for shifting the element. A return element is provided for returning the mechanism to its withdrawn position.</p> |
