摘要： A rotary casting apparatus for molding hollow articles of synthetic plastic is described employing a plurality of hollow molds which are heated and rotated within a fixed oven. The molds and molded articles therein are cooled rapidly while they remain within the oven by injecting cool, moist air into such oven from an external blower fan and a sprayer which sprays water into the air inlet of such fan. Improved rotation and support means are provided for the molds, including a common tubular drive shaft which rotates all of the molds about a common axis and a plurality of rotor means for rotating each of the molds about another axis perpendicular to such common axis. The rotor means are coupled by bevel gears to a second drive shaft extending through the common drive shaft. Each of the molds is rotationally mounted on bearings which are supported on the common drive shaft. The bearings at the inner ends of the molds each include a tubular fixed shaft about which the mold is rotated by the rotor means and which also vents gas from such mold. A scraper ring of low adhesion material is attached to the fixed bearing shaft within each mold and spaced a predetermined distance from its inner surface to provide the molded article with a mounting flange portion of predetermined thickness and inner diameter.
摘要翻译：使用多个中空模具描述用于模制合成塑料的中空制品的旋转铸造设备，所述中空模具在固定烘箱内被加热和旋转。将其中的模具和模制品通过从外部鼓风机风扇和喷雾器向这种风扇的空气入口喷射喷雾器而将冷却的潮湿空气注入这样的烘箱中而迅速地冷却，同时它们保持在烘箱内。提供了用于模具的改进的旋转和支撑装置，包括围绕公共轴线旋转所有模具的共同的管状驱动轴和用于围绕垂直于该共同轴线的另一个轴线旋转每个模具的多个转子装置。转子装置通过锥齿轮联接到延伸通过公共驱动轴的第二驱动轴。每个模具旋转地安装在支撑在公共驱动轴上的轴承上。模具内端的轴承各自包括管状固定轴，模具通过该固定轴由转子装置旋转，并且还从该模具排出气体。在每个模具内的固定轴承轴上安装有低粘合材料的刮环，并与其内表面隔开预定的距离，为模制品提供预定厚度和内径的安装凸缘部分。
