Precision glass molding formation device capable of synchronously taking-core

Abstract

This invention discloses a precision glass molding device capable of fetching cores synchronously including a first model, a second model set opposite to the first model along an axes, a locating piece set coaxially with the two models and covering them and a set of core fetching pieces set between the locating piece and the two models, thus, when a material is placed between the two models to carry out pre-closing the moulds till the material reaches to the central thickness to protrude a rest material out of the two models and the core fetching piece moves along the axes to cut off the rest and take out the core.

Description

Technical field [0001] The invention relates to a glass molding equipment, in particular to a precise glass mold forming device capable of synchronous core removal. Background technique [0002] The existing Precision Glass Molding technology uses the relative shaping surface of the two mold cores to press the high-temperature softened glass material to form a primary embryo body, which must be moved to a core Take the machine for turning and grinding to produce practical glass lenses. [0003] Such as figure 1 As shown, the general core removal machine 1 includes a clamping jig 101 that can firmly clamp a primary embryo body 2 and is arranged along an axial direction, and a grinding wheel 102 that can grind the primary embryo body 2. Although the core removal machine 1 can achieve the purpose of core removal of molded glass, the specifications of glass molded lenses are becoming stricter nowadays, whether it is eccentricity, appearance, external dimensions, and some aspheric le...

AI Technical Summary

Problems solved by technology

[0004] 1. When the primordial body 2 is clamped by the clamping fixture 101, a central line of the primordial body 2 is likely to deviate from the axis, resulting in excessive eccentricity, and the cored glass will also have a large Errors, especially, will also affect the subsequent coating yield

[0005] 2. The clamping fixture 101 is easy to pinch the glass mirror surface, and the defect rate is high

[0006] 3. In order to prevent the clamping fixture 101 from pinching the glass mirror surface, a layer of oil can be applied to the surface of the primordial body 2 before the core is taken, and the oil must be removed with a cleaning agent (trichloroethylene) after the core is taken. However, some primordial bodies 2 have been oiled for too long, and the oil atomization on the surface cannot be removed even after cleaning, so they must be polished again. In this way, not only will oiling, degreasing, polishing and other operations And prolong the process, and it is easy to damage the mirror surface during polishing

[0007] Four, utilize this grinding wheel 102 car to grind the surplus material of this embryonic body 2, can consume grinding stone, increase cost

[0008] 5. After the pressing of the primary body 2 is completed, it must go through the process of core taking, turning and grinding, which not only increases the production process and consumes man-hours, but also fails to improve production capacity and quality
