Claims (4)
- 注型成形金型に設けたブッシュに注入ノズルを挿入すると共に該注入ノズルを注型成形金型に対して着脱自在に装着し、該注入ノズルから注型成形金型のキャビティ内に熱硬化性の樹脂を注入し、該樹脂を加熱硬化させて成形する際に樹脂の硬化により収縮する量を補うために注入ノズルから樹脂を注入し続け、この後、注型成形金型のキャビティ内の樹脂及び注入ノズル内の樹脂を硬化させた後、注入ノズルを注型成形金型に対して取り外すと共にブッシュから抜き、この後、脱型する注型成形金型装置において、注入ノズルを加熱する加熱手段を設けたことを特徴とする注型成形金型装置。
- 加熱手段は注入ノズルの周りに巻き付けたバンドヒータであることを特徴とする請求項1記載の注型成形金型装置。
- 加熱手段は電磁誘導加熱装置であることを特徴とする請求項1記載の注型成形金型装置。
- 注入ノズルの先端が最も温度が高くなるように電磁誘導加熱装置のコイルユニットを設けたことを特徴とする請求項3記載の注型成形金型装置。
