20110115119 | COOLING FETCH METHOD OF PREFORMS - The present invention discloses a cooling fetch method of preforms, and the method includes: using a first fetch mechanism for fetching each preform formed in a mold of an injection molding machine from the mold; a second fetch mechanism for fetching each preform on the first fetch mechanism. After the second fetch mechanism fetches a predetermined quantity of preforms, the preforms on second fetch mechanism are unloaded sequentially, such that the injection molding process and the cooling process of the preforms are separated. The timing of fetching each preform on the second fetch mechanism is controlled for assuring a good cooling effect of each preform. | 05-19-2011 |
