- 上端に開口部を有するネック部と、このネック部に連続する胴部と、この胴部に連続する前記胴部よりも肉厚の底部とを有する有底筒状のプリフォームを射出成形するための金型装置であって、
前記ネック部の外面を形成するネック型と、
前記プリフォームの胴部及び底部の外面を形成する射出キャビティ型と、
前記プリフォームの内面を少なくとも形成する射出コア型と、を有し、
該射出コア型が、
前記射出キャビティ型内に挿入されて前記プリフォームの内面を形成する内方コア型と、
先端部が前記ネック型に型締めされて前記プリフォームの上端面を形成すると共に、射出空間内の圧力変動に応じて摺動可能に前記内方コア型を保持する外方コア型と、を有し、前記内方コア型が、前記射出空間内の圧力上昇に伴って前記射出キャビティ型の底面との距離が広がるように摺動可能に構成されており、
且つ前記内方コア型の前記射出キャビティ型の外側に向かう移動を規制する規制手段を備えることを特徴とする金型装置。 - 請求項1に記載の金型装置において、
前記内方コア型は、前記プリフォームを射出成形する際に、前記射出空間内が所定圧力以上となると前記射出キャビティ型の外側に向かって所定距離だけ移動可能に構成されていることを特徴とする金型装置。 - 請求項1又は2に記載の金型装置において、
前記規制手段が、前記内方コア型を前記射出キャビティ型内に向かって所定の付勢力で付勢する付勢部材であることを特徴とする金型装置。 - 請求項1〜3の何れか一項に記載の金型装置を備えることを特徴とする射出成形装置。
- 請求項4に記載の射出成形装置を用いたプリフォームの射出成形方法であって、
前記射出空間内に原材料を連続的に射出して前記内方コア型を第1の位置から第2の位置まで移動させながら前記射出空間内に原材料を充填した後、当該射出空間内への原材料の射出を継続して前記内方コア型を前記第2の位置に保持した状態で前記射出空間内の原材料を冷却して硬化させることを特徴とするプリフォームの射出成形方法。 - 請求項5に記載のプリフォームの射出成形方法において、
前記射出空間を形成する前記射出キャビティ型及び前記射出コア型を冷却した状態で、当該射出空間内に原材料を射出することを特徴とするプリフォームの射出成形方法。
