Abstract

The invention provides a method for making a hollow doll's head (10) by injection molding a thermoplastic elastomer around a removable mold core (26). The major dimension of the mold core (26) is larger than the opening in the doll's head (10) through which the core (26) 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 (10) and then reassembled for reuse.

Description

Background technique [0001] The present invention relates to hollow toy parts, in particular, to soft hollow doll heads. The invention also relates to methods of making soft hollow toy parts using thermoplastic elastomers, and molds for these methods. Background technique [0002] Traditionally, soft hollow toy parts or doll heads have been hollow molded, dip molded or rotomolded from rubber latex or PVC, or blow molded from thermoplastic elastomers. However, none of these conventional methods can produce hollow parts with controllable and precise wall thickness and opening dimensions. Despite this, however, hollow molding and spin casting using PVC have been the dominant manufacturing methods over the past half century due to its softness and ease of processing, and PVC is used to make The main material for the head of a one-piece hollow toy doll. [0003] However, in the past ten years, various studies have shown that PVC materials are not good for the environment, and ...
