- 所要形状に成形され、軽量でかつ保形性を有する発泡樹脂基材(21)と、この発泡樹脂基材(21)の裏面に一体化される所定パターン形状の樹脂リブ(22)とからなる積層構造体(20)を全体、あるいは一部に採用してなる自動車用内装部品(10)の製造方法において、
前記積層構造体(20)は、発泡樹脂基材(21)の素材である発泡樹脂シート(S)を加熱軟化処理後、成形金型(41,42)内に投入し、成形金型(41,42)同士の型締めにより、発泡樹脂シート(S)を成形金型(41,42)のキャビティ形状に沿って所要形状に賦形した後、冷却用エアを上記樹脂リブ(22)を成形するために成形下型(42)に穿設されている上記溝部(424)を通じて発泡樹脂基材(21)の裏面に吹き付けて冷却する発泡樹脂基材(21)の成形工程と、
成形上型(41)を下降操作し、成形上下型(41,42)間で発泡樹脂基材(21)を圧縮保持しながら成形下型(42)の溝部(424)内に溶融樹脂(M1)を射出充填して、樹脂リブ(22)を発泡樹脂基材(21)の裏面側に一体化する樹脂リブ(22)の成形工程と、
から製作されることを特徴とする自動車用内装部品の製造方法。 - 前記成形下型(42)の溝部(424)内に溶融樹脂(M1)を射出充填する前に成形下型(42)の溝部(424)に配置したバキューム機構により、溝部(424)内のエアを外部に強制排気することで、溶融樹脂(M1)の流動性を高めたことを特徴とする請求項1に記載の自動車用内装部品の製造方法。
- 軽量で、かつ保形性を有する発泡樹脂基材(21)と、この発泡樹脂基材(21)の裏面に一体化される樹脂リブ(22)とからなる積層構造体(20)を成形する成形金型(40)であって、この成形金型(40)は、相互に型締め、型開き可能な成形上型(41)、並びに成形下型(42)と、成形下型(42)に連設され、樹脂リブ(22)の素材である溶融樹脂(M1)を供給する射出機(43)とから構成され、成形上型(41)には、発泡樹脂基材(21)の成形時、この発泡樹脂基材(21)を成形上型(41)の型面に吸着保持するための真空吸引機構(44)が付設されているとともに、成形下型(42)には、上記樹脂リブ(22)のパターン形状に即して穿設された溝部(424)の隅々にエアが隈なくいきわたるように、溝部(424)の所定部位の底面にエアブロー機構(45)が配設されていることを特徴とする積層構造体の成形金型。
