Description
管本体と、前記管本体の外側に連接された板状部分と、を有する発泡成形体であって、
前記発泡成形体の発泡倍率が2倍未満であり、
前記管本体における前記板状部分が連接された箇所の周囲の肉厚Aと、前記板状部分の肉厚Bと、の関係である前記肉厚B/前記肉厚Aの値が2.82未満である、ことを特徴とする。
また、本発明にかかる発泡成形体は、
管本体と、前記管本体の外側に連接された板状部分と、を有する発泡成形体であって、
前記発泡成形体の発泡倍率が2倍以上であり、
前記管本体における前記板状部分が連接された箇所の周囲の肉厚Aと、前記板状部分の肉厚Bと、の関係である前記肉厚B/前記肉厚Aの値が2.88未満である、ことを特徴とする。
まず、図7〜図9を参照しながら、本発明の一態様にかかる発泡成形体1の概要について説明する。図7〜図9は、本発明の一態様にかかる発泡成形体1の構成例を示す図である。
まず、図7〜図9を参照しながら、本実施形態のインパネダクト1の構成例について説明する。図7は、インパネダクト1の概略平面図であり、エアコンユニット(図示せず)に接続するための供給部105を有する側のインパネダクト1を示す。図8は、図7に示す嵌め合い部102d周辺の概略平面図を示し、図9は、図8のD−D’断面図を示す。
引張破壊伸び:後述する本実施形態の成形方法により得られたインパネダクト1の管本体X1を切り出し、−10℃で保管後に、JIS K−7113に準じて2号形試験片として引張速度を50mm/分で測定を行った値を引張破壊伸びとした。
引張弾性率:後述する本実施形態の成形方法により得られたインパネダクト1の管本体X1を切り出し、常温(例えば、23℃)で、JIS K−7113に準じて2号形試験片として引張速度を50mm/分で測定を行った値を引張弾性率とした。
次に、図10〜図12を参照しながら、本実施形態のインパネダクト1の成形方法例について説明する。図10は分割金型の開状態、図11は分割金型の閉状態を分割金型側面から示した図である。図12は、分割金型の閉状態を2つの分割金型の当接面から分割金型12a側について示した図である。
上述した実施形態としてのインパネダクト1は、例えば、図14に示す成形方法で成形することも可能である。
こうした樹脂シートの厚み、押出速度、押出方向の肉厚等の調整は、公知の各種方法を用いてよい。
次に、実施例により上述したインパネダクト1について説明する。但し、以下の実施例に限定されるものではない。
本実施例では、インパネダクト1の原料樹脂として、以下の原料配合で作成した発泡パリソンを使用し、シリンダにガス供給口を有するスクリュー式押出機を備えた発泡ブロー成形機を用い、ガス供給口より窒素の超臨界流体を添加し、上述した図10〜図12と同様な成形方法で図15に示す簡易な形状のインパネダクト1を成形した。図15に示すインパネダクト1は、管部101の両端に嵌め合い部102を設けた簡易な構造になっている。図15に示すインパネダクト1も図7に示すインパネダクト1と同様に、管部101、嵌め合い部102から構成される管本体X1(図9参照)にフランジ部103が連接されている。このため、図15に示すインパネダクト1においてフランジ部103が連接された箇所の切断面(図15のE−E断面)は、図9と同様な形状になる。
