A mandrel is provided on the axis of the die hole formed in the die, and a cylindrical mold is provided which is integrally provided on the mold body and whose protrusion is inserted into the gap between the die and the mandrel. The annular gap between the die and the cylindrical mold is the inner pipe forming part of the multi-circular pipe, and the annular gap between the die and the cylindrical mold is the outer pipe forming part, and the extrusion direction from the protruding end of the cylindrical valley mold is The annular gap between the die and the mandrel at the front is used as the overlapping part of the inner and outer tubes, and the base of the cylindrical mold is made flexible so that the protruding end side of the cylindrical mold can be moved and fixed in the radial direction. A mold for an extrusion molding machine that is characterized by:
