PROBLEM TO BE SOLVED: To provide a foam molding machine for suitably exhausting the air from a mold according to a foam flow of an urethane raw material by reducing a cost and stabilizing an operation. SOLUTION: An air bleeding hole 13 communicating within a mold and a valve 14 for opening/closing the hole 13 are provided at an upper part of an upper mold 7. The shapes of the hole 13 and the valve 14 are each formed in a flared shape toward a mold interior. A pressure reducing unit for pressure reducing in the mold for air bleeding in the mold from the hole 13 is provided. The valve is abolished, a film is provided at the upper mold, and the air in the upper mold of an upper surface side of the film is bled from the hole 13. |
