Abstract
【解決手段】金型面31を加熱するために、積層体を含む加熱装置が用意され、積層体は、磁界を発生させる複数の巻線コイル19を有するコイル担体層21と、金型面に隣接する導電性上部層25とを含み、表面を加熱するために、上部層25に電流が誘導され、低抵抗層23を含む問題解決策により効率的に加熱することができ、低抵抗層23は、それ自体ほとんど熱を発生させることなく、電流を上部層25に導き、導電フレーム装置は、裏当て層27との信頼できる接続を可能にするために、上部層25の下に上部層25の周縁部を囲んで設けることができ、上部層25の下にある2つの層間に画定され、作用面31の大部分の下に延びて少なくとも一部が流体で満たされる空洞を有する金型。
【選択図】図3
Description
特に、光ガイドプレートを形成するためにブランクを加圧成形/エンボス加工する場合、加圧力を均等にし、剪断力をなくすことで、良好な光特性が得られる。図7および図8に示す、流体を充填した空洞47は、表面および金型にわたって圧力を均等にし、剪断力を全く伝達しない。能動的加熱なしに使用することができるし、または代替の能動的加熱手段と共に使用することもできるこの特徴がある結果として、流体を充填される空洞47が使用されない金型と比較して、完成品の品質および/または歩留まりが改善される。
上部層25は、多くの場合非常に薄くすることができ、加熱および冷却時に、それぞれある程度膨張および収縮することがあるとしても、電流が流入する縁部において、裏当て層27への信頼できる接続が形成されなければならない。これは、金型半体の作用面全体を囲む、例えば、銅でできた導電フレーム63によって達成することができる。上部層25は、上部層の縁部で、浮動する態様で導電フレーム63上に置かれる。これは図11にも示されている。
上記のように光ガイドを製造する場合、縁部が特別な注意を必要とすることがある。樹脂がその縁部で溶融しすぎた場合、縁部において、光が意図しない形で漏れることがある。縁部でのブランクの厚さが薄くなることもある。同時に、ブランク面全体にわたって圧力をかけることが望ましい。
Claims (3)
- 作用面を用いてブランクをエンボス加工/加圧成形する金型であって、前記作用面に上部層(25)を含む積層体を有し、前記上部層が、エンボス加工/加圧成形中に加熱される金型において、前記作用面から見て、前記積層体内で、前記上部層の下にある2つの層間に画定され、前記作用面の大部分の下に延び、少なくとも一部が流体で満たされる空洞(47)を特徴とする金型。
- 請求項1に記載の金型において、前記作用面がブランクと接触しない状態で、すでに前記空洞内の圧力が大気圧よりも高く、そのため、前記上部層がある程度出っ張ることを特徴とする金型。
- 作用面を用いてブランクをエンボス加工/加圧成形する金型を使用する製造方法であって、前記金型は、前記作用面に上部層を含む積層体を有し、前記上部層は、エンボス加工/加圧成形中に加熱される金型において、前記作用面から見て、前記積層体内で、前記上部層の下にある2つの層間に画定される空洞によって前記ブランクに圧力を加え、前記空洞は、前記作用面の大部分の下に延び、少なくとも一部が流体で満たされることを特徴とする製造方法。
