Abstract

Abstract During injection moulding container-like objects a mould cavity of a mould is bounded by a core and a jacket divided in its longitudinal direction into two jacket parts. This mould is opened and closed by a relative axial displacement of the core on the one hand of the jacket on the other, and by a relative radial displacement of the jacket parts.
