Device for demoulding an annularly closed object from a mould with mould core

摘要

Device for demoulding annularly closed objects made of an elastic material from a mould having a mould core to shape the inner surface of the objects. The core is longitudinally split and expandable. Removing fingers project from the partial joint openings of the expanded core, which removing fingers stretch the objects to be removed and thereby lift them from the mould core, and subsequently can be removed from the core in the longitudinal direction together with the objects to be demoulded.
