Patent ID: 8029268

Claim:
A cooling fetch apparatus of preforms, installed on a side of an injection molding machine, for fetching a preform formed by a mold of the injection molding machine, and the cooling fetch apparatus of preforms comprising: a first fetch mechanism, having a first transmission arm and a first clamp portion, and the first transmission arm being linearly displaceable in a first direction, and the first clamp portion being disposed at an end of the first transmission arm for synchronously moving the first transmission arm, and the first fetch mechanism using the first clamp portion to fetch a plurality of preforms formed by the mold of the injection molding machine from the mold, the first clamp portion including a plurality of preform suction pipes having a corresponding preform formed by the mold, the first clamp portion performing a cooling effect of a first stage to an external brink of the preforms, and after the injection molding machine removes each preform, an injection molding is performed to the preforms again to prepare the first fetch mechanism for a next fetching process; a second fetch mechanism, having a second transmission arm and a second clamp portion, and the second transmission arm being linearly displaceable in a second direction, the second clamp portion including a plurality cooling pipes disposed thereon, and the second clamp portion being disposed at an end of the second transmission arm, and moving synchronously with the second transmission arm, and the second fetch mechanism using the second clamp portion to fetch the plurality of preforms on the first clamp portion of the first fetch mechanism, such that the first clamp portion of the first fetch mechanism and the second clamp portion of the second fetch mechanism perform a cooling effect of a second stage to both external and internal brinks of each preform simultaneously, and continue performing a cooling effect of a third stage to the internal brink of each preform after the preforms are fetched, and after the second clamp portion fetches a predetermined quantity of preforms, and each preform situated on the second clamp portion is removed sequentially in a batch; wherein the first transmission arm drives the first clamp portion to be linearly displaced between a start position, a target position and a plurality of cooling positions; and the target position is situated in the mold, the cooling positions are situated on a side corresponding to the second fetch mechanism and are selectively set relative to the cooling pipes, and the start position is situated between the target position and the cooling positions, so that when the mold has not complete the injection molding, the first clamp portion is situated at the start position to wait for opening the mold.
