Description
Technical field:
The present invention relates to a kind of die (die) of moulded glass, particularly relate to a kind of die and renovation process thereof that is easy to processing regenerated moulded glass.
Technical background:
By a series of precious metal die patents of MAT as can be known, in the precious metal of high inactivity, add element, can suppress crystal grain-growth, it is applied on the high temperature model, can make die have the excellent model life-span.For example Japanese patent application publication No. 63-103836 is disclosed; be to use Ir-Re-C directly as the protective membrane of wolfram varbide ground; and the precious metal between protective membrane and ground does not design the die in middle layer, under 800 ℃ model temperature, can reach the model life-span more than 2000 times.But precious metal film layer is difficult for strip, can only remove by lapping mode, is reclaiming, when regenerating die, need expend the plenty of time.
Diamond-like carbon film (diamond-like carbon; DLC), when moulded glass, can provide splendid release property, and as long as when regeneration is by oxygen gas plasma (O
2Plasma) can its complete etching is clean, die is as long as polishing can be reused by plated film a little, and the regenerated program is simple.For example Japanese patent application publication No. 01-320233 is disclosed, is to use the protective membrane of DLC as ground, and SiC or Si are then used in the middle layer
3N
4Japanese patent application publication No. 06-191864 is to use the protective membrane of the DLC of sputter as ground, and the middle layer has two layers, is respectively the DLC that SiC and ion are implanted.When diamond-like carbon film thickness is too thick, can produce internal stress, film is easily peeled off; When thickness was too thin, the Elements Diffusion that makes base material easily was to the protective membrane top layer, caused the diamond-like carbon film variable color and reacted with glass, lost its release property.Though above-mentioned document proposes solution; But the present invention proposes the means different with above-mentioned document in addition.
And Japanese patent application publication No. 11-079760; be to use the protective membrane of DLC as ground; the middle layer is for can grind the β-SiC that cuts; thickness is 3-50mm; utilize oxygen gas plasma that the DLC etching is clean during regeneration; again β-SiC is ground the precise shape of cutting to required again, reproducible number of times is decided according to the thickness of β-SiC.Though its recyclability is good, because of intermediate layer thickness is too thick, the time of plated film needs hundreds of hours consuming time in the first time, and is too consuming time and production cost also caused detrimentally affect.
Summary of the invention:
Main purpose of the present invention provides a kind of die and renovation process thereof of moulded glass; have good recyclability, short characteristic of recovery time; also has the Elements Diffusion that prevents base material characteristic to the protective membrane top layer; and the sticking power between increase diamond-like carbon film and die ground and the thermotolerance of diamond-like carbon film, thereby the recyclability and the work-ing life of lifting die.
