WIPO Patent Application WO/2018/109907
Kind Code:
A1
Abstract:
One embodiment of the present disclosure is a rod-shaped molding core for manufacturing an elongated, hollow molded article. The molding core comprises a plurality of segments that combine to form a single rod-shaped body. The plurality of segments includes a rod-shaped first segment, rod-shaped second and third segments, and rod-shaped fourth and fifth segments. When combined, the entire outer periphery of the first segment is surrounded by the rest of the plurality of segments. The second and third segments are disposed so as to contact the first segment and sandwich the first segment therebetween in a first direction orthogonal to the longitudinal direction of the first segment, thereby constituting part of the outer circumference of the rod-shaped body. The fourth and fifth segments are disposed so as to contact the first segment and sandwich the first segment therebetween in a second direction orthogonal to the first direction, thereby constituting part of the outer circumference of the rod-shaped body.
