Abstract
An extrusion die is provided to improve wear resistance and to suppress damage to the shaping section of the core die. The core die consists of a plurality of individually prepared protruding rod members 5 that includes a protrusion section 3a and a base section 3b that extends in the upstream direction with respect to the metal flow. The protruding rod members 5 are arranged in parallel in locating grooves 12 fabricated on the male die assembly 2. Each protruding rod member 5 has a base section 3b and a transverse locking notch 7 so that a stopper 8 locks all the protruding rod members 5 to prevent them from shifting in the axial direction of the protruding rod member.
