INJECTION MOLD AND PRODUCTION OF CONNECTOR INSULATOR

摘要

PROBLEM TO BE SOLVED: To suppress the deformation of a plate-shaped core for forming a slit hole caused by the injection pressure of a resin at a time of resin molding to enhance productivity as a connector insulator in an injection mold for molding the connector insulator having the slit hole between a side wall in a lateral direction and a terminal row. SOLUTION: An injection mold for a connector insulator having a slit hole between a side wall and the terminal row of a terminal implanted region is constituted inclusive of a fixed mold and a movable mold. The movable mold 51 has a movable mold cavity block 511 having a cavity surface 252a molding the peripheral surface of the terminal implanted region including the slit hole along with a rear surface, a first cavity core 252c for molding the terminal hole of the terminal implanted region and a second cavity core 252d for molding the slit hole and the resin gate 252b on the single side of a terminal row direction and a resin sub-gate 511a on the outside of the second cavity core are provided to the movable mold cavity block.
