ABSTRACT:
The present invention discloses a cooling fetch apparatus of performs, and the apparatus includes: a first fetch mechanism, moved back and forth, for fetching each perform formed in a mold of an injection molding machine from the mold; a second fetch mechanism, moved back and forth, for fetching each preform on the first fetch mechanism. After the second fetch mechanism fetches a predetermined quantity of performs, the performs on second fetch mechanism are unloaded sequentially, such that the injection molding process and the cooling process of the performs are separated. The timing of fetching each perform on the second fetch mechanism is controlled for assuring a good cooling effect of each preform.
