Abstract

PURPOSE:A metallic mold capable of molding pipes irrespective of diameter without replacing the metallic mold entirely through selecting the aperture of die extrusion holes. CONSTITUTION:A mandrel 2 is mounted ahead of a screw present in the end of an extruder 6 with spider, and an inside mold 1 on the top is tapered to a smaller diameter gradually ahead. A die 4 is provided with an extrusion hole 3 at the center, and the extrusion hole 3 is tapered to a smaller diameter outward. The extrusion hole 3 is arranged to have the same taper as that of the inside mold 1. Dies 4 are provided in more than one to have a different size of outside aperture of the ex-trusion hole 3 and are mounted on outer perimeter of the inside mold 1 of the mandrel 2 in more than one in the order of larger outside aperture of the extrusion hole 3.
