PROBLEM TO BE SOLVED: To provide a mold for an assembling core, easy in handling for carrying, repeatedly usable, easy in disassembling/assembling, being lightweight, and excellent in productivity. SOLUTION: In this mold 1 for the assembling core composed of two divided bodies, the mold for the assembling core is characterized in that the divided bodies are formed to be expandable by mutually connecting a circular arc-shaped body A and a circular arc-shaped body B via a hinge X in one end part in the circumferential direction, and have respectively fitting means 10 and 11 in the other end in the circumferential direction of the circular arc-shaped body A and the circular arc-shaped body B, and are formed to be assembled into a cylindrical synthetic resin core by combining the two divided bodies by the fitting means 10 and 11, and are also formed by arranging one group of through-holes 14 on the peripheral surface of the circular arc-shaped body A and the circular arc-shaped body B, and a through-hole reinforcing rib 18 is further provided in a part or the whole of an edge of the through-holes 14 on the inner surface side of the circular arc-shaped body A and the circular arc-shaped body B.
