Problems solved by technology

[0011] However, there is such a problem that the flow direction adjustment piece is one piece and has a sheet shape, so it is easy to fall due to the flow of the foamable resin material, and it is impossible to sufficiently eliminate the gas remaining.

Deformed example 1

[0101] Figure 8 (a) is a figure for explaining Modification 1 of the protrusion part 16, which shows the state in which the support member 14 was set in the molding die, and Figure 5 The same enlarged view of the main part. The protrusions 16 - 1 and 16 - 2 of Modification 1 are arranged in the width direction of the mold surface shape deformation portion 58 of the convex line (that is, in the width direction of the shape deformation portion 26 of the concave line of the vehicle seat cushion 10 ). ) are separated from each other. Preferably, the entire width dimension W3 of the plurality of protrusions 16 is larger than the width dimension W1 of the die surface shape deforming portion 58 . Furthermore, the protrusion part 16-2 on the downstream side in the flow direction of the foamable resin material is set higher than the protrusion part 16-1 on the upstream side. In addition, the heights of the protrusions 16 - 1 and the protrusions 16 - 2 may be the same height, or ma...

Deformed example 2

[0104] Figure 8 (b) is a diagram for explaining Modification 2 of the protruding portion 16, which shows a state in which the support member 14 is set in the molding die, and Figure 5 The same enlarged view of the main part. In Modification 2, the plurality of protrusions 16 - 1 , 16 - 2 are all formed in a cylindrical shape with a circular cross section. A plurality of protrusions 16 - 1 , 16 - 2 are formed by one piece of sheet-like member. The protrusion 16 - 1 is formed into a circular cross-section and sewn to the supporting member 14 by a joint portion 71 extending along the extending direction. The protrusion 16 - 2 is formed to have a circular cross-section and is sewn to the support member 14 by one joint portion 72 continuous in the extending direction. In addition, it is possible to make non-joint between the respective joining portions with respect to the support member 14 . By forming and joining each protrusion with one joint in this way, it is possible to f...

Deformed example 3

[0106] Figure 9 It is a figure for explaining the modification 3 of the protrusion part 16, and it shows the state which set the support member 14 in the molding die, and Figure 5 The same enlarged view of the main part. In Modification 3, one protrusion 16 is provided for one shape deformation portion 26 . By providing one protrusion 16 in this way, the structure can be further simplified and the component cost can be reduced.

Abstract

Provided are a foam-molded article, a method for producing a foam-molded article, a forming mold structure for a foam-molded article, and a vehicle seating pad made using a foam-molded article, the foregoing making it possible to prevent the occurrence of underfilled sections with respect to recessed sections and protruding sections formed on the surface of the foam-molded article, and possible tocurb any increase in cost. A foam-molded article 10 is obtained by integral molding of: a foam body 12 that is composed of a foamable resin material M and has a shape deformation section 26 of troughs and ridges on the surface; and a seat-shaped support material 14 for covering a surface opposing a formation surface of the shape deformation section 26 on the foam body 12. Provided to the supportmaterial 14 of the foam-molded article 10 is a projecting section 16 in a region facing the shape deformation section 26 and / or adjacent to said region. The projecting section 16 is of a pillar shapestretching along a direction of extension of the shape deformation section 26.

Description

technical field [0001] The present invention relates to a molded foam product in which a foam main body and a supporting member are integrally molded, a method for manufacturing the molded foam product, and a mold structure for molding the molded foam product. Background technique [0002] Foam molded products such as elastic polyurethane are used for seat cushions and the like used in seats in vehicles. The above-mentioned foam molded article has, for example, a foamable main body made of a foamable resin material and a support member for reinforcing the foamable main body. The liquid foamable resin material is injected and foamed, thereby integrally molding the foam body and the supporting member. [0003] During the integral molding process, the gas in the cavity is discharged from between the clamping surfaces of the molding mold to the outside along with the progress of the foamable resin material, but when the gas is not exhausted and remains in the cavity , it will ...
