Abstract: Wheel molding apparatus for molding thermoplastic containers or other articles, the apparatus having a multiplicity of sets (10) of opposed, separable radially aligned mold halves (12, 14) that travel in a circular path about a horizontal axis. The inner of the mold halves (14) is separated from the outer of the mold halves (12) at the 12:00 o'clock position of the mold set that includes such mold halves to permit the molded article to be ejected from the mold set. However, the ejection of the molded article should not take place until after the separation of the mold halves, and this requires that the molded article be positively retained within the outer mold half until it is desired to eject the article therefrom.

However, if the comparison indicates that the part is still in the open mold, the controller outputs an ejection signal to actuate the ejector to cycle again. This sequence continues until a comparison of an actual image of the open mold with the ideal image indicates that the part is no longer in the open mold.

This is achieved by using a mold whose walls forming the mold cavity themselves consist of material that conducts heat poorly or are suitably coated, by first evacuating the mold cavity, filling the evacuated mold with the expandable molding compound at excess pressure and, after the filling operation, introducing vapor into the evacuated mold. After turning off the vapor pressure, the mold cavity is again evacuated and the vacuum is maintained during the stabilization phase. After the stabilization phase, the mold is opened and the molded part is ejected by excess pressure (FIG. 1).
