Abstract:
Apparatus for molding articles from a thermoplastic material, said apparatus comprising:a plurality of circumferentially spaced mold sets arranged for rotation in a vertical plane, each mold set comprising a radially outermost mold half and a radially innermost mold half, the innermost mold half in each mold set being separable from the outermost mold half in said mold set to permit a container that has been molded therein to be ejected therefrom; anda translatable pin extending through a passage in each radially outermost mold half and being translatable relative to the outermost mold half solely along a rectilinear path relative to said radially outermost mold half, said translatable pin having an undercut near a free end thereof and engaging an article in the mold set that includes such radially outermost mold half in an interference fit, extension of said translatable pin within said radially outermost mold half being effective to move said article away from said radially outermost mold half and to eliminate the interference fit, whereby the article is ejected from said radially outermost mold half.
