ABSTRACT:
An apparatus for injection molding of plastic lure skirts utilizes an openable mold wherein a conic cavity is formed between a pair of mold plates and a conic insert is selectively advanced to abut the inner surface of the conic cavity. A plurality of grooves are formed in the conic cavity which communicates with a tubular section wherein the soft plastic is introduced such that a body portion and a stranded skirt are formed when plastic is injected between the mold plates and the conic insert. The apparatus may be used for forming double skirted lures or conventional non-skirted lures by internal injection when a stripper bar is used to partially seal the mold distribution channel.
