Mold for foam molding and method for producing foam-molded member

摘要

Disclosed is a mold for foam molding capable of making the operation to attach a reinforcing member to an inner surface of a mold easier, capable of sufficiently preventing entry of foam synthetic resin between the reinforcing member and the inner surface of the mold at the time of foam-molding, and capable of preventing the reinforcing member from becoming wrinkled; and also provided is a method for producing a foam-molded member which has a reinforcing member using this mold for foam molding. A mold 20 for foam molding is used to foam-mold a seat pad 1 which is provided with a seat pad main body 2 and a reinforcing member 10 disposed on the back side of the seat pad main body 2. At the time of foam-molding, the reinforcing member 10 is disposed inside the mold 20 and an end edge of the reinforcing member 10 is secured to the inner surface of the mold 20 by a securing means. A tension application means is provided which applies tension to the end edge of the reinforcing member 10 in a direction to separate from the securing means.

主权项

1. A mold for foam molding adopted for foam-molding a foam-molded member which is provided with a foam-molded body and a sheet-shaped reinforcing member disposed along at least a part of a surface of the foam-molded body,
wherein the reinforcing member comprises an opening that is a through hole at a surface of the reinforcing member; the mold comprises a projecting portion, securing members disposed around the projecting portion, and a tension application member; and at least one of the securing members is disposed closer to the projecting portion than the tension application member is; and wherein in a state in which the reinforcing member is secured to an inner surface of the mold, the projecting portion is inserted through the opening of the reinforcing member; a peripheral edge portion of the opening is at least partially secured to the inner surface of the mold by the securing members; and tension is applied to the peripheral edge portion by the tension application member in a direction so as to urge separation from the securing members and the opening, thereby tensioning the peripheral edge portion of the opening.
