<p>A mould extraction device for cosmetic pencil cores, comprising fixing means for a mould in which at least one core has been previously cast in a through hole provided in said mould, locking means for a core holder to fix this latter coaxially with the through hole of the mould in which the ore was cast, at least one pusher positioned coaxially with the hole and of diameter such as to be able to penetrate into it, and drive means for mutually moving said pusher and said mould from a first position in which said pusher is external to said hole to a second position in which said pusher is internal to said hole and occupies it for a length such as to be able to expel the core present in the hole. The device presents means for injecting pressurized fluid between that pusher surface facing the core and said core, such as to facilitate core extraction from the hole.</p> |
