特徴とする円盤状記録媒体成形用金型。 In a mold for an injection molding machine for a disk-shaped recording medium having a through hole in the center, the cut of the molten resin gate part of the molded product is filled into the cavity through the sprue bush on the axis of the mold. This is carried out by the spring force of a spring that presses a gate cut pin disposed coaxially and oppositely to the sprue bush, and the nozzle touch force of the injection molding machine to the sprue bush. Mold for forming disc-shaped recording media.
