ABSTRACT:
A bucket shaped container having a rim opening smaller than the diameter of the sidewall thereof is injection molded from thermoplastic material using a die set including a molding core which collapses to allow axial removal of the molded container from the mold. The molding core comprises a plurality of individual, wedge shaped outer core sections which collectively form a continuous molding surface and are slidably mounted on a tapered inner core to allow axial sliding movement of the outer core sections relative to the inner core. Each of the outer core sections is also mounted for radial sliding movement on a mounting plate which circumscribes the molding core and is mounted for reciprocating axial movement relative to the inner core. Reciprocation of the mounting plate produces simultaneous axial and radial movement of the outer core sections throughout their entire lengths between an expanded molding position and a collapsed container releasing position. A plurality of rim molding segments mounted for radial sliding movement on the mounting plate automatically shift between molding and release positions in synchronism with the axial travel of the outer core sections.
