Description
(1-1.全体構成)
図1は、本実施の形態に従う樹脂成形装置10の正面図である。樹脂成形装置10は、いわゆるコンプレッションモールド法を用いることによって、樹脂成形品を製造するように構成されている。
図2は、下型320の一部分の平面図である。図3は、上型310、下型320及び中間プレート323の断面を含む図である。図3において、下型320の一部分の断面は、図2のIII-III断面に対応している。
上述のような樹脂成形装置10において、仮に、離型フィルム400が下型320に吸着された状態で、液状樹脂供給機構900によって離型フィルム400上に熱硬化性を有する液状樹脂が吐出されるとする。この場合には、下型320の熱が離型フィルム400上に供給された液状樹脂に伝達されやすいため、液状樹脂が適切なタイミングよりも早くに硬化する可能性がある。
図4は、樹脂成形装置10による樹脂成形品の製造手順を示すフローチャートである。図4に示される処理は、フィルム供給機構500に離型フィルム400がセットされており、成形型300が型開きした状態で、制御部700によって実行される。
以上のように、本実施の形態に従う樹脂成形装置10において、制御部700は、離型フィルム400と下型320とが離れた状態で離型フィルム400上に液状樹脂を供給するように液状樹脂供給機構900を制御する。樹脂成形装置10においては、離型フィルム400と下型320とが物理的に離れた状態で離型フィルム400上に液状樹脂が供給されるため、下型320の熱が離型フィルム400上の液状樹脂に伝達されにくい。したがって、樹脂成形装置10によれば、液状樹脂が適切なタイミングよりも早くに硬化する事態を抑制することができる。
上記実施の形態の思想は、以上で説明された実施の形態に限定されない。以下、上記実施の形態の思想を適用できる他の実施の形態の一例について説明する。
