The invention provides a method for making a hollow doll's head by injection molding a thermoplastic elastomer around a removable mold core. The major dimension of the mold core is larger than the opening in the doll's head through which the core is to be removed after the injection molding is complete. For large mold cores and relatively small openings, the invention provides a multiple piece core section which is designed to be removed piece by piece through the opening in the doll's head and then reassembled for reuse.

1. A method for making a hollow doll head, the method comprising the steps of:a) providing an injection moldable flexible thermoplastic elastomer; b) providing a mold for the hollow doll head, the mold comprising exterior mold parts and an interior core, wherein the exterior mold parts are spaced apart from the interior core to define a cavity in the shape of the hollow doll head to be formed; c) assembling the exterior mold parts to form a junction between the exterior mold parts such that a part line is created at the junction of the exterior mold parts when the hollow doll head is injection molded, the head having ears, the parting line forming a substantially continuous circle extending around the top of the head and above the ears; d) injection molding the thermoplastic elastomer into the mold cavity to form the hollow doll head, the head having an opening for removing the interior core, the diameter of the opening being smaller than the diameter of the core to pass through the opening; e) opening the exterior mold parts to release the hollow doll head and the interior core; and f) separating the interior core from the head.
