In an injection moulding machine for the moulding of articles from highly tacky materials such as uncured urethane elastomers injected material is prevented. after injection, from flowing out from the mould (15, 16) along the injection passage (18), by means of a sealing device (30) which comprises a sealing face (46) of nylon or like material, resiliently loaded e.g. by a coil spring (40), against the mould face (19A, 19B), and adapted for sliding thereover to cover or uncover the mould injection passage (18). <IMAGE> |
