Abstract

The invention provides an apparatus (100) for producing a foam-molded member (300) having a skin (150) characterized by comprising a first mold (111) where the outer surface (142) of a core material (140) is arranged opposite to a mold surface (115), a second mold (112) provided to open / close freely relative to the first mold (111) with the outer surface (152) of the skin (150), that has a rolled-in portion (155) formed to be bendable, arranged opposite to a mold surface (116), a bending device (120) for bending the rolled-in portion (155) in a state where the first mold (111) and second mold (112) are closed so that the rolled-in portion (155) faces the outer surface (147) at the end (145) of the core material (140), a welded portion (130) for forming a seal portion (200) which prevents leakage of a foam body (180) filling the gap between the inner surface (141) of the core material (140); and the inner surface (151) of the skin (150) by welding the end (145) of the core material (140) and the rolled-in portion (155), and a filling portion (160) for filling the foam body (180).

Description

technical field [0001] The present invention relates to a manufacturing device for a skinned molded foam part, a method for manufacturing a skinned molded foam part, and a skinned molded foam part. Background technique [0002] In interior parts used in automobiles and households, foam molded parts with skins having a three-layer structure of skin layer-foam layer-core material layer are often used. In the foam molded part with skin, foam is filled between the core material and the skin arranged in the molding die, and these are integrated to form a molded product. When manufacturing a foam molded part with a skin, a sealing part is formed in order to prevent leakage of the foam from between the skin and the core material (see Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2001-145926 [0004] In the sealing portion of Patent Document 1, the end surface of the end portion of the core material is exposed to the outside of the mo...
