Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案はカバーガラスの成形型に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cover glass mold.
従来のカバーガラスの成形型は第４図に示すように、
カーボン材を加工した下型１と上型２より構成されてい
る。下型１と上型２の間にガラス３を挾み加熱，押圧す
ることにより、カバーガラスが成形される。As shown in FIG. 4, a conventional cover glass mold is:
It is composed of a lower mold 1 and an upper mold 2 formed by processing a carbon material. The cover glass is formed by holding and pressing the glass 3 between the lower mold 1 and the upper mold 2.
更に、排気孔を有するカバーガラスは、カバーガラス
を成形後、ダイヤモンドドリルあるいは超硬ドリルを用
いて排気孔を切削加工していた。Further, in the case of a cover glass having an exhaust hole, after forming the cover glass, the exhaust hole is cut using a diamond drill or a carbide drill.
一方、第５図に示すように成形と同時に排気孔を加工
する成形型は、排気孔に相当する型に円柱状のピン６を
有している。On the other hand, as shown in FIG. 5, a molding die for forming an exhaust hole simultaneously with molding has a cylindrical pin 6 in a mold corresponding to the exhaust hole.
この従来のカバーガラスの排気孔加工方法では、ダイ
ヤモンドドリルや超硬ドリルを用いて孔加工を行ってい
るため、ドリルの消耗が激しく、又加工された排気孔の
精度が出にくいという問題があった。又、排気孔の精度
を上げるためには、ダイヤモンドドリルを頻繁に交換し
なければならず、かなりの費用を要していた。In this conventional method of drilling holes in a cover glass, since holes are drilled using a diamond drill or a carbide drill, there is a problem that the drills are consumed greatly and the precision of the drilled exhaust holes is difficult to obtain. Was. Also, in order to increase the accuracy of the exhaust hole, the diamond drill must be replaced frequently, which has required a considerable cost.
一方、ダイヤモンドドリル等で加工された排気孔は、
ドリルの抜け部にガラスカケあるいは微少クラックが発
生し次工程でのクラックの原因となっていた。更に成形
と同時に排気孔を加工する成形型においては、排気孔加
工用ピンが円柱状のため、ガラスが加熱成形された後の
冷却過程で、ガラスの熱膨張率がカーボン材より大き
く、ピン６に力がかかり、ピン６が折れてしまい成形型
の補充にかなりの費用を要していた。On the other hand, the exhaust holes machined with a diamond drill etc.
Glass chipping or microcracks were formed at the drilled portions, causing cracks in the next process. Further, in a molding die for processing the exhaust holes simultaneously with the molding, since the exhaust hole processing pins are cylindrical, the thermal expansion coefficient of the glass is larger than that of the carbon material during the cooling process after the glass is formed by heating, and the pin 6 , And the pins 6 were broken, and replenishment of the mold required considerable expense.
