ABSTRACT:
The present invention relates to a device for cooling and removing molded parts, which device has particular utility with an index molding machine having a rotary turret block with at least two movable mold halves thereon. The device includes a carrier plate having a plurality of tubes for receiving and cooling at least one molded part mounted to a first surface thereof and a plurality of blowing tubes for applying a cooling fluid to external surfaces of at least one molded part, while the at least one molded part is positioned on one of the faces of a rotary turret block, mounted to a second surface of the carrier plate. The device further has an actuation system for moving the carrier plate between a first position where the receiving and cooling tubes are aligned with the at least one molded part and a second position where the at least one molded part is being cooled within the receiving and cooling tubes and the cooling fluid applying blowing tubes are positioned adjacent a respective turret block face. The actuation system comprises a cam plate having a guide track therein, at least one cam follower connected to the carrier plate, and a linear drive system for causing the cam follower to move along the guide track and thereby cause movement of the carrier plate from the first position to the second position and vice versa.
