EXTRUSION BLOW MOLDING MACHINE

PROBLEM TO BE SOLVED: To provide an extrusion blow molding machine, capable of accurately supplying high quality parison into a mold, and producing a molded article which is high quality with high productivity.SOLUTION: An extrusion blow molding machine 1 comprises: a parison supply device 3 for restraining parison which is discharged vertically downward from a die head 2D of an extruder 2, and supplying the parison to a parison supply position P1 separated from the die head 2D; a mold transport/opening and closing device 4 for transporting plural molds M, installed to a horizontal plane, to a take-out position P2 from the parison supply position P1 continuously and sequentially, performing closing operation of the molds M sandwiching the parison, and then performing open operation of the mold M for taking out a molded article; and a blow device 5 for blowing blow air into the parison sandwiched in each mold M during transport of the molds M reaching the take-out position P2 from the parison supply position P1. The parison supply device 3 has a pick-up mechanism 30 for gripping the parison by moving in a horizontal direction during moving downward.SELECTED DRAWING: Figure 1 【課題】金型内に精度良く高品質のパリソンを供給することができ、高品質且つ高い生産性で成形物を製造することができる押出ブロー成形機を提供する。【解決手段】押出ブロー成形機１は、押出機２のダイヘッド２Ｄから鉛直下向きに吐出されたパリソンを拘束してダイヘッド２Ｄから離れたパリソン供給位置Ｐ１に供給するパリソン供給装置３と、水平面内に設置された複数の金型Ｍを、順次連続的にパリソン供給位置Ｐ１から取り出し位置Ｐ２に向けて搬送し、パリソンを挟む金型Ｍの閉動作を行うと共に成形物を取り出す金型の開動作を行う金型搬送・開閉装置４と、パリソン供給位置３から取り出し位置Ｐ２に至る金型Ｍの搬送中に金型Ｍに挟持されたパリソン内にブローエアを吹き込むブロー装置５とを備え、パリソン供給装置３は、下方に移動しながら水平方向に移動してパリソンをつかむピックアップ機構３０を備える。【選択図】図１
