Abstract:
A mold for injection molding a unitary artificial soft plastic fishing lure having a main body portion with at least a pair of integral fins extending at angles from opposite sides of said main body portion and a longitudinal central axis through the main body portion, said mold comprising:a pair of mating mold halves including mirror image cavities therein with each cavity defining half of said main body portion, each mold halve including a notch that defines one of said fins, each notch having an entrance opening communicating with its associated cavity and a closed end, said notches being completely air tight except for its entrance opening; said mold halves having abutting surfaces that contact each other in a single plane when said cavities are aligned for casting, and said longitudinal central axis being located in said plane; an entrance gate for molten plastic at one end of said mold, and the opposite end of said mold being closed; wherein, when molten plastic is forced into said mold under pressure, the only escape path for air in said mold is past said abutting mold surfaces, and air is trapped and compressed in said notches when molten plastic flows past their entrance openings and into said notches so as to create a pressure in said notches that is great enough to eject said lure body from said mold when said mold halves are separated.
