A description is given of apparatus for the production of containers in plastic material, such as jars, bottles or the like, suitable for being connected to a traditional machine for injection moulding and comprising a fixed plate or back plate (30) connected to an injection system for the moulding of the plastic and a movable plate carrying one or more punches (21) for the production of parisons, where the movable plate is carried by a frame sliding axially in the direction of the back plate and is attached thereto via a pair of tracks whereon it slides in transverse direction. The back plate comprises at least one central station provided with injection systems for the moulding of the parisons and at least two lateral stations or modules provided with dies (17, 18) with respective seats for accommodating the parisons obtained, and the movable plate comprises at least two identical stations provided with punches and with blowing systems connected to the punches in such a way that, when the two plates are in contact, in one of the stations the moulding of the parisons takes place and simultaneously in the other the blowing of the parisons for the production of finished containers takes place. In this way it is possible to obtain by means of the same apparatus both the production of parisons and the production of finished plastic containers, and in particular one or two types of finished products. |
