Patent
A system for the post-treatment of preforms (9) produced by means of injection moulding, including a removal element (4) having at least one receiving element (5) for receiving a preform (9), and a device for moving the removal element (4) between two tool halves of an opened injection moulding mould and for moving the removal element (4) out of the opened injection moulding mould, a post-treatment element (6) having at least one post-treatment pin (7) having a pin-shaped passage element (7), of which one end can be connected to the environment or a vacuum or reduced-pressure source and of which the other end has an outlet (18) for a coolant, and a motion device with which the removal element (4) can be reciprocated relative to the post-treatment element (6) between a first position in which the post-treatment pin (7) is positioned within the receiving element (5) and a second position in which the post-treatment pin (7) is not positioned within the receiving element (5), wherein the removal element (4) and the post-treatment element (6) are so designed that in the first position coolant can be introduced by way of the coolant inlet into a preform held in the receiving element (5) in such a way that it can flow between the inside wall of the preform (9) and the outside wall of the pin-shaped passage element (7) to the coolant outlet (18) and can be discharged by way of the passage element (7).
