Abstract: The present invention is a method of manufacturing a foam molded product in which a foam molded product (1A, 1B) is formed by integrally adhering together a foam body (2) that is formed by the foaming of a foaming raw material, and an air-permeable component (3) using an apparatus for manufacturing a foam molded product (1A, 1B) that is provided with a cavity (23) between a plurality of mold components (21, 22, 31) that is defined by respective cavity surfaces (21a, 22a, 31a) of the mold components (21, 22, 31).

Abstract: A mold that: makes it possible to manufacture a molded foam body wherein a reinforcing member extends to a portion of the outer face of the molded body main body that corresponds to a parting line in the inner face of the cavity of the mold; and prevents molding problems stemming from the reinforcing member getting into the aforementioned parting line. Also: a method for manufacturing a molded foam body using the aforementioned mold; and a molded foam body manufactured thereby. The aforementioned mold (1) is provided with a seal member (7) that seals the space between mating faces (2a, 3a) of mold parts (2, 3) when the mold is fastened, and said seal member (7) is designed so as to be able to seal the space between the mating faces (2a, 3a) even if the reinforcing member (22) gets in between the mating faces (2a, 3a) on the cavity (4) side of the seal member (7).

Also: a method for manufacturing a molded foam body using the aforementioned mold; and a molded foam body manufactured thereby. A recessed step portion (6) that faces the cavity (4) of the aforementioned mold (1) is provided in the mating face (3a) of at least one part (3) of said mold (1), at at least a portion of the parting line (P) (formed in the inner face of the cavity (4)) adjacent to which the reinforcing member (22) is disposed.

Abstract: A mold, a molding machine, and a foamed molded body manufacturing method are provided that are capable of more reliably preventing ingress of foamed resin into a gas discharge hole using a gas-impermeable member and capable of adequately discharging gas inside the cavity to the cavity outside through the gas discharge hole during foam molding, and that are also capable of achieving good design characteristics in a foamed molded body. A gas discharge hole 5 is provided at a cavity 4 inner face of a mold 1 and discharges gas inside the cavity 4 to outside the cavity 4. A gas-permeable member 6 is disposed inside the cavity 4 of the mold 1 so as to cover the gas discharge hole 5, and a gas-impermeable member 8 is disposed on the gas discharge hole 5 side of the gas-permeable member 6 so as to face the gas discharge hole 5.

Abstract: Ridge portions 9 are provided to be continuously present in orthogonally intersecting directions by forming plural recessed holes 8 in the upper surface of an under-thighs portion 2 and an under-buttocks portion 3 of a seat pad 1 for a vehicle. The height of each ridge portion 9, i.e. the depth h of each recessed hole 8, is preferably in the range of 2 to 40 mm, more preferably in the range of 5 to 20 mm, the width w of each recessed hole 8 is preferably in the range of 10 to 30 mm, more preferably in the range of 20 to 30 mm, and the area of an opening of each recessed hole 8 is preferably in the range of 50 to 1000 mm2, more preferably in the range of 100 to 900 mm2. Accordingly, the present invention can provide a seat pad, which is excellent in soft sensation of touch of a surface thereof, satisfactory in the properties of supporting an occupant, and can be produced by integral foam molding.
