    • The present invention relates to an apparatus and a method of cooling molded preforms. The apparatus and method make advantageous use of air amplifiers to create a flow of cooling air over the molded preforms. In a first embodiment of the present invention, the air amplifiers are mounted to a part removal and cooling robot. In a second embodiment of the present invention, a plurality of air amplifier stations are positioned about an index block to cool the molded preforms. In a third embodiment of the present invention, a vacuuming system is provided to improve the adherence of the air flow created by the air amplifiers to the exterior surfaces of the molded preforms. In a fourth embodiment of the present invention, the air amplifiers are mounted to a movable plate and each amplifier has an internal bore sized to receive a molded preform to be cooled.
    • 本发明涉及冷却模制预制件的装置和方法。 该装置和方法有利于利用空气放大器在模制的预成型件上产生冷却空气流。 在本发明的第一实施例中,空气放大器安装到部件去除和冷却机器人上。 在本发明的第二实施例中,多个空气放大器工作站围绕分度块定位以冷却模制的预制件。 在本发明的第三实施例中,提供了一种真空系统,以提高由空气放大器产生的空气流与模制的预成型件的外表面的粘附性。 在本发明的第四实施例中,空气放大器安装到可移动板上,每个放大器具有内孔,其尺寸适于接收待冷却的模制预制件。
