FIELD: metallurgy.
SUBSTANCE: invention relates to a method for demoulding annular elastomer mouldings from a mould core. Injection mould has inner mould core (1) and outer mould jaws, mouldings are produced parallel to one another in annular mould cavities (5) of mould core (1). After removing the outer mould jaws, mould core (1), which contains produced elastomer mouldings (9) on the surface thereof, is set in such a high rotational speed about longitudinal axis (12) thereof that the inside diameter of the elastomer mouldings is increased on account of centrifugal force to such an extent that the mouldings are released from mould cavities (5) and can be removed in the axial direction from mould core (1) while they are still rotating.
EFFECT: invention provides a device for demoulding annular elastomer mouldings having a simple design, prevents subsequent processing of mouldings and is cheap to manufacture.
