発泡構造体の製造方法および発泡構造体
Abstract:
【課題】発泡体の成形過程でエア逃し通路により発泡成形空間内からのエア逃しを行う技術において、簡単な構成で、発泡樹脂材料が漏れ出して発泡成形型に付着することを防止し、歩留りを低下させることなく、発泡構造体の品質の向上および生産性の向上を図る。 【解決手段】基材と表皮材との間に発泡体を充填するインストルメントパネル等の発泡構造体の製造方法であって、前記基材または表皮材のシール面に延設方向に沿って複数の線状突起を設け、前記シール面と前記複数の線状突起とで複数のエア逃し孔を形成し、発泡樹脂材料を充填する工程において、発泡樹脂材料をその反応固化により前記エア逃し孔内に留めるよう構成した。 【選択図】図14
Abstract(English):

To provide a method of manufacturing a foam structure, and a technology of performing air purging from a foam molding space through an air purging passage in a foam molding process to achieve improvement of a quality and productivity of the foam structure by a simple configuration, by preventing leaking out and adhering of a foaming resin material to a foam molding mold, and without reducing a yield.SOLUTION: There is provided a method for manufacturing a foam structure such as an instrument panel in which a foam body is filled between a base material and a skin material, in which: a plurality of linear protrusions is provided along an extending direction on a sealing surface of the base material or the skin material; a plurality of air purging holes is formed by the sealing surface and the plurality of linear protrusions; and in a process of filling a foaming resin material, the foaming resin material is retained in the air purging holes by causing reaction solidification.SELECTED DRAWING: Figure 14
