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 havingat least one tooth facing a pawl that has at least one tooth inside a locking head utilizes acore that defines at least a portion of the abutment surface tooth and at least a portion of asurface of the pawl that includes the at least one pawl tooth. The core is movable inrelation to a first other mold part and is separated from a second other mold part notsooner than the first other mold part is separated from the second other mold part tothereby enable (a) the pawl to flex into a space vacated by movement of the first othermold part and (b) the abutment wall to flex into a space also vacated by movement of thefirst other mold part during separation of the first other mold part from the second othermold part so that the tie can be removed from the mold without significantly damaging.either the at least one pawl tooth or the at least one abutment surface tooth.
