    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.

    Abstract translation: 本发明提供了一种通过在可移除的模芯(26)周围注射模塑热塑性弹性体来制造中空玩偶的头部(10)的方法。 模芯(26)的主要尺寸大于玩偶头部(10)中的开口,在注射成型完成之后芯体(26)将通过该开口去除。 对于大模芯和相对较小的开口,本发明提供了一种多片芯部分,其被设计成通过娃娃头部(10)中的开口逐个移除,然后重新组装以供重新使用。
