Removal of injection-molded tie from mold by temporarily retaining core between pawl and abutment surface of tie

摘要

A method of injection molding a tie that includes an abutment wall surface (20) having at least one tooth (22) facing a pawl (18) that has at least one tooth (24) inside a locking head utilizes a core (14) that defines at least a portion of the abutment surface tooth and at least a portion of a surface of the pawl that includes the at least one pawl tooth. The core (14) is movable in relation to a first other mold part (10) and is separated from a second other mold part (12) not sooner than the first other mold part is separated from the second other mold part to thereby enable (a) the pawl (18) to flex into a space (30) vacated by movement of the first other mold part and (b) the abutment wall (16) to flex into a space (31) also vacated by movement of the first other mold part during separation of the first other mold part from the second other mold part so that the tie can be removed from the mold without significantly damaging either the at least one pawl tooth (24) or the at least one abutment surface tooth (22). <IMAGE>
