A first rotating member is rotatably attached to the first die, and provided at its inner end surface with a first helical gear pattern. A second rotating member is rotatably attached to the second die, provided at its inner end surface with a second helical gear pattern, and rotated in a direction opposite to the direction of the first rotating member while the molded product is removed.
