し該段部により成形品の内面にアンダーカツトを
形成するコアーピンを備えて成る射出成形用金型
において、上記コアーピンの小外径部の外周部に
肉厚が上記コアーピンの段部の段差より大きく且
つ段部に向かう先端縁が楔状のスリーブを小外径
部の外面に沿つて段部方向に摺動自在に装着した
ことを特徴とする射出成形用金型。 An injection mold comprising a core pin having a large outer diameter part and a small outer diameter part connected to each other and a stepped part on the outer surface of the core pin, which forms an undercut on the inner surface of the molded product by the stepped part. A sleeve having a wall thickness larger than the step of the stepped portion of the core pin and having a wedge-shaped tip edge facing the stepped portion is attached to the outer periphery of the small outer diameter portion so as to be slidable along the outer surface of the small outer diameter portion in the direction of the stepped portion. An injection mold that is characterized by:
