<p>A mold in molding is vertically ventilated, for temperature regulation, at positions in the circumferential direction around a figure surface (1a, 2a, 3a) of the mold. The ventilation is made for cooling by using a joint path (1d, 2d, 3d) formed by a figure surface-side section of a mold (1, 2, 3) and joint surfaces (1b1, 1c1) (2b1, 2c1) (3b1, 3c1) where inner and outer mold members (1b, 1c) (2b, 2c) (3b, 3c), forming sections outside the joint surfaces, are joined. The structure enables to easily and inexpensively obtain various shapes depending on variation in the shape in the axial direction of the figure surface, and enables to achieve, with high cooling effect, temperature management suitable for variation in the shape in the axial direction of the figure surface.</p> |
