With developing rapidly for electronic technology, the also diversification of the requirement to injection mo(u)lding, current printer, money press, figure
As electronic products such as sensors, inside needs the product of glass and plastic rubber shaping, while it is certain to ensure that glass has with plastic cement
Pulling force, glass both sides guarantee is made when flushing with plastic rubber member surface, cannot be combined closely after glass and plastic rubber shaping；Glass reaches
With gripping orientation after plastic rubber shaping, moulding is highly greater than glass, causes upper surface to ensure same plane.
The content of the invention
The invention aims to solve above-mentioned technical problem, and a kind of moulding process of glass plastic cement is provided, so as to
Realize that glass is not easily disconnected from plastic cement, and surface is without segment difference.In order to achieve the above object, technical solution of the present invention is as follows：
The moulding process of glass plastic cement, comprises the following steps：
S1, the son that enters in male template forms cell body to indentation in male template, vitreum is put into cell body and is positioned, feature die
During matched moulds, enter son and male template upper surface flush, and the pushing block pressed glass body 0.05mm in caster, caster and male template
Between die cavity height it is consistent with vitreum, pushing block is return and is flushed with caster, and the THICKNESS CONTROL of vitreum is in 1.82mm-
Between 1.88mm；
S2, is molded using vitreum both sides, and injection adopts the compound-material of PC and 30%GF.
Specifically, the vitreum include body, located at the extension of body both sides, the upper and lower surface of the plastic body with
The upper and lower surface of the body is flushed.
Specifically, the extension is vertical at the center of the side of the body.
Specifically, the outer lower end of the extension is provided with 45 ° of chamferings.
Specifically, open up fluted in the extension.
Specifically, the groove is square or isosceles trapezoid.
Compared with prior art, the beneficial effect of the moulding process of glass plastic cement of the present invention is mainly reflected in：Vitreum
Positioning and pre-pressing process make it engage completely with plastic parts, and the extension on vitreum makes it not depart from easily with plastic parts, and
The upper and lower surface of vitreum and plastic parts improves the yields of injection mo(u)lding without obvious segment difference, reduces cost.
