    • A cooling tube assembly for operating on a malleable molded plastic part. The cooling tube assembly comprising a porous tube/insert having a profiled inner conditioning surface, and a vacuum structure configured to cooperate with the porous tube. In use, the vacuum develops a reduced pressure adjacent the inner conditioning surface to cause an outer surface of the malleable molded plastic part, locatable within the cooling tube assembly, to contact the inner conditioning surface of the porous insert so as to allow a substantial portion of the outer surface of the malleable part, upon cooling, to attain a profile substantially corresponding to the profile of the inner conditioning surface. The cooling tube assembly having a porous insert The conditioning body having a porous member that includes an inner porous portion formed from a thermally conductive first porous material that is at least partially enclosed by an outer porous portion formed from a thermally conductive second porous material preferably having a higher porosity than the first porous material. The outer porous portion is configured for providing a fluid communication pathway between the pressure structure and the inner porous portion that supports a fast and homogenous pressure response.
    • 用于在可锻塑料部件上操作的冷却管组件。 冷却管组件包括具有成型内部调节表面的多孔管/插入件,以及构造成与多孔管配合的真空结构。 在使用中,真空在内部调节表面附近产生减小的压力,以使位于冷却管组件内的可延展的模制塑料部件的外表面与多孔插入件的内部调节表面接触,从而允许大部分 在可延展部分的外表面上,在冷却时,获得基本对应于内调节表面轮廓的轮廓。 具有多孔插件的冷却管组件具有多孔构件的调节体包括由导热第一多孔材料形成的内部多孔部分,所述内部多孔部分至少部分地被由导热的第二多孔材料形成的外部多孔部分包围,所述外部多孔部分优选具有 比第一多孔材料具有更高的孔隙率。 外部多孔部分构造成在压力结构和内部多孔部分之间提供支撑快速和均匀的压力响应的流体连通路径。
