Plastic container injection-moulding machine equipped with quick mould-change arrangement

摘要

Injection-moulding machine for producing plastic containers, comprising an upper platen (1), a moving mould-carrying platen (2), a support bar (3) for lips constituted by two respective separable members (15a, 15b), a plurality of male members (6) applied to said upper platen (1), a cavity-carrying platen (4) in which there are provided removable means (16) adapted to delimitate the travel of said moving mould-carrying platen (2) towards the cavity-carrying platen (4), so that the moving mould-carrying platen (2) can be positioned at a pre-selectable distance with respect to the cavity-carrying platen (4). Said removable means (16) are referably constituted substantially by a number of resting cylinders, or parallelepipeds, arranged parallel with respect to each other and having the same height, the axis of which is parallel to the moving direction of the moving mould-carrying platen (2).
