    • A molding die and a method for molding a molded article including a foam layer made up of faces extended in a plurality of directions are provided, by which all of the faces can grow up to a predetermined expansion ratio or more. To this end, a molding die 1 includes a stationary die including a main die 2 and a slide die 3 movable relative to the main die 2, and a movable die 4. The slide die 3 partially faces a cavity C and can move in a direction (Y direction) different from a die clamping/die opening direction (X direction). When a foam layer a2 made up of a face a21 orthogonal to the die clamping/die opening direction and a face a22 other than the face a21 grows in the cavity C, at least the slide die 3 moves in Y direction, whereby both of the faces a21 and a22 of the foam layer a2 can grow to satisfy a predetermined expansion ratio.
    • 本发明提供一种成型模具和成型体的成型体,其中,所述成形品包括由沿多个方向延伸的面构成的泡沫层,通过该成形体,所有面都可以成长至预定的膨胀比以上。 为此,成型模具1包括固定模具,其包括主模具2和相对于主模具2可移动的滑动模具3以及可动模具4.滑动模具3部分地面向空腔C,并且可以在 方向(Y方向)不同于模具夹紧/模具打开方向(X方向)。 当由与模具夹紧/开模方向正交的面a21构成的泡沫层a2和除了面a21以外的面a22在空腔C中生长时,至少滑动模3沿Y方向移动, 泡沫层a2的表面a21和a22可以生长以满足预定的膨胀比。
