Abstract:
A method of molding a unitary artificial soft plastic fishing lure having a main body portion and a longitudinal central axis with integral fins extending from opposite sides of said main body portion at an acute angle to said central axis, comprising the steps of:A. providing a mold having mold halves, each mold halve including a cavity therein, with each cavity defining part of said main body portion and each cavity including a notch that extends at said acute angle and defines a fin and has an entrance opening communicating with the cavity and a closed end with an end surface;B. closing said mold by abutting said mold halves against each other;C. providing an entrance gate in said mold for molten plastic;D. forcing molten plastic under pressure into said cavities through said entrance gate;E. expelling air from said cavities as the molten plastic advances;F. trapping air in each notch between said end surface of said closed end and the molten plastic by closing said entrance opening with molten plastic as the molten plastic moves past said entrance opening;G. flowing the molten plastic into the notches to mold said fins and compress the air trapped in said notches;H. cooling the molten plastic until it solidifies while preventing the trapped compressed air from escaping from said notches;I. ejecting said fishing lure from said mold by moving said mold halves apart so as to release pressure on said body portion and thereby allow the air compressed in said notches to eject said fins from said notches.
