Description
ここで、図1は、本発明の一実施の形態を示す断面図であり、図2は、メス型内に溶融樹脂塊が投入された直後におけるプリフォームの圧縮成形用金型の断面図である。
図1および図2に示すように、プリフォームの圧縮成形用金型10は、プリフォーム14を圧縮成形するものである。この圧縮成形用金型10は、メス型11と、メス型11に対応して設けられ、メス型11との間で溶融樹脂塊16を圧縮成形するオス型12と、メス型11上にオス型12を囲んで設けられ、プリフォーム14の口部14aを成形する摺動可能な2つのスライド型13、13とを備えている。
まず、押出機から押出された熱可塑性樹脂(溶融樹脂材料)が、圧縮成形用金型10のメス型11上でカッタにより切り離され、溶融樹脂塊16となって圧縮成形用金型10のメス型11内に投下される(図2参照)。その後、オス型12およびスライド型13がメス型11上に移動して、スライド型13がメス型11に当接し、更にオス型12が下降してメス型11内に挿入される(図1参照)。この際、メス型11内に入れられた溶融樹脂塊16は、オス型12により圧縮され、メス型11、オス型12、およびスライド型13により賦形される。その後、このようにして賦形された溶融樹脂塊16は、冷却されてプリフォーム14として成形される。その後、圧縮成形用金型10が開となり、プリフォーム14が離型される。
次に、本発明の具体的実施例を説明する。
11 メス型
12 オス型
13 スライド型
14 プリフォーム
16 溶融樹脂塊
