（産業上の利用分野）
本発明は、ガラスを底形する為の成形型に係り、特にプ
レス成形後に研磨を必要としない高精度のガラス成形体
を得る為の成形型に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a mold for shaping the bottom of glass, and in particular to a mold for obtaining a high-precision glass molded body that does not require polishing after press molding. Regarding types.
（従来の技術〉
ガラス成形体の成形型に要求される面性能としては、次
のものが挙げられる。(Prior Art) Surface properties required of a mold for a glass molded article include the following.
■酸化されにくいこと。■Not easily oxidized.
■高温下でもガラスと融着を起こさないこと。■Do not cause fusion with glass even at high temperatures.
■光学鏡面研磨が容易なこと。■Optical mirror polishing is easy.
■引っ掻き傷の生じにくい高い硬度を有すること。■Have high hardness that makes it difficult to scratch.
■プレス時の衝撃に耐える機械的強度を有すること。■Have mechanical strength to withstand impact during pressing.
上記のような面性能の要求されるガラス成形体の成形型
としては、従来超硬より戊る成形型の内面に、ＴｉＣ，
ＴｉＮ或いはＴ１ＣＮの０．５〜１０μｍの薄膜が被覆
された成形型が用いられてきた。As molds for glass molded bodies that require the above-mentioned surface performance, TiC,
Molds coated with a 0.5-10 μm thin film of TiN or T1CN have been used.
（発明が解決しようとする課題）
ところで、上記の成形型は、５００〜６００℃の高温で
ガラス（酸化物）と接触する為、内面の薄膜中のＴｉが
酸化して薄膜が荒れ、ガラス成分中の酸化物が付着して
濡れ性が低下し、ガラス成形体の型離れが悪くなって、
寿命が短いものである。(Problem to be Solved by the Invention) By the way, since the above-mentioned mold comes into contact with glass (oxide) at a high temperature of 500 to 600°C, the Ti in the thin film on the inner surface oxidizes and the thin film becomes rough, causing the glass components to oxidize. The oxides inside the glass adhere to it, reducing wettability and making it difficult for the glass molded product to release from the mold.
It has a short lifespan.
そこで本発明は、ガラス成形体の型離れが良好で、長寿
命の成形型を提供しようとするものである。Therefore, the present invention aims to provide a mold that allows a glass molded article to be easily released from the mold and has a long life.

It is formed by coating iN with a thin film in which 5 to 40 wt% of Pt or a Pt group alloy is dispersed at the atomic level.

らかくなり、型離れが阻害されるからである。The reason why the thin film coated on the inner surface of the mold for the glass molded body of the present invention is made of a material in which 5 to 40 wt% of Pt or Pt group alloy is dispersed at the atomic level in TiN is that it is hard and moldable. This is to impart the oxidation resistance of Pt or a Pt group alloy to TiN, which has good release properties.If it is less than 5wt%, it will not be possible to impart oxidation resistance, and if it exceeds 4Qwt%, the hardness will become soft and it will not release from the mold. This is because it is inhibited.

Since the oxides in the glass components do not adhere, the wettability does not deteriorate, the glass molded product is easily released from the mold, and has a long life.

で、寿命か著しく伸びたことが判る。On the other hand, as a conventional example, a mold for a glass molded body made of the same material and the same dimensions as in the example was placed in a vacuum container, and after the vacuum degree in the vacuum container was set to I Xl0-' Tor r r, argon gas was 2X10-2Torr. Next, a negative voltage of 1.5 KV was applied to the mold, and glow discharge was performed for 30 minutes to clean the mold. Then evacuate and N
2 gases were introduced to give 4 Xl0-'Torr. After that, 1 layer of TiN is applied to the inner surface of the mold by heating with a heater.
A mold for a glass molded body was obtained by vapor deposition. (Japanese Unexamined Patent Publication No. 118638/1989 is a prior art document.) Barium borosilicate glass was molded at 700°C using the molds for the glass molded bodies of the examples and conventional examples obtained in this way. The life of the mold was reached after 300 moldings, but the mold of Example could mold glass up to 2,000 times, indicating that its life was significantly extended.
