PROBLEM TO BE SOLVED: To provide a mold for soap which reliably releases air from a cavity, suppresses occurrence of burrs in a product, and has high productivity.SOLUTION: In a forming region of an air vent 15 in a parting surface PL of a mold 1A on one side, a plurality of linear grooves 18 extending in an air discharging direction in the air vent 15 are continuously formed at no interval in a direction Y perpendicular to the discharging direction and angle projections 19 are formed between two adjacent linear grooves 18 and 18 in the perpendicular direction Y. In cross sectional view in the perpendicular direction Y, the linear grooves 18 are cut inward in a thickness direction of the mold 1A on one side and the angle projections 19 project outward in the thickness direction. In the parting surface PL of a mold 1B on the other side, when a cavity 10 is formed by butting parting surfaces PL of both the mold 1A and the mold 1B against each other, a groove opposed region 1B1 opposing to the plurality of linear grooves 18 is flat, in which a groove is not formed. |
