Abstract
A demoulding unit for a pot-like recess of an injection-moulded component is designed in such a way that no parting arises on a bottom side of the injection-moulded component and at least this part of the bottom side can be used as a sealing surface. The demoulding unit has a movable inner demoulding element, a front side of which is used to form the burr-free bottom side. In order to produce projections provided on the inside of the recess, projection demoulding elements are provided. The projection demoulding elements may be moved in a circumferential direction by means of a holding/releasing element during the demoulding.
