Abstract
【効果】本発明の成形同時加飾成形品の製造方法によれば、得られる成形同時加飾成形品が絶えずA金型の側に保持され、A金型の側に付設されているエジェクタピンによって、成形同時加飾成形品を突き出すことができるため、回収装置が常に同じ方向で作動することができるので、大量生産時において連続的かつ安定的に成形同時両面加飾成形品を回収することができる効果がある。

Claims (4)
- 第一加飾シートをエジェクタピンが付設されている射出成形金型のA金型に配置し、第二加飾シートを射出成形金型のB金型に配置した後、A金型とB金型との型閉めにより成形空間部を形成し、該成形空間部に成形樹脂を注入して射出成形品を形成すると同時に第一加飾シートおよび第二加飾シートを一体化形成させる成形同時加飾成形品の製造方法であって、型開き後に成形同時加飾成形品が射出成形金型のA金型に保持されるようにしたことを特徴とする成形同時加飾成形品の製造方法。
- 前記請求項1に記載の成形同時加飾成形品の製造方法に用いる第一加飾シートであって、表面に金型Aと仮密着しやすいオーバーコート層が設けられたことを特徴とする第一加飾シート。
- 前記請求項1に記載の成形同時加飾成形品の製造方法に用いる第二加飾シートであって、表面に金型Bと離型しやすい離型オーバーコート層が設けられたことを特徴とする第二加飾シート。
- 前記請求項1に記載の成形同時加飾成形品の製造方法に用いる射出成形金型であって、B金型に型開きと同時に作動する第二エジェクタピンが付設されていることを特徴とする射出成形金型。
