Abstract

The invention relates to a mold insert protective device used to be arranged on a template with a mold insert. The mold insert is provided with a molding surface; and the mold insert protective device comprises a protective cover which is fixed relative to the template and covers the molding surface of the mold insert. The mold insert protective device can protect the molding surface of the mold insert from being polluted by outside impurities and being collided by other objects in the condition that the template with the mold insert is in a stationary state or in a moving state.

Description

technical field [0001] The invention relates to a mold core protection device which can be installed on a template to protect the molding surface of the mold core from pollution and damage, and a mold with the mold core protection device. Background technique [0002] At present, there are mainly two methods for manufacturing optical lenses: compression molding and injection molding. Compression molding technology is mainly used to manufacture optical lenses with a diameter of more than 100 mm (see "Quartz Glass Molding by Precision Glass Molding Method", Trans.IEE Jpn., pp.494-497, 2002); while injection molding is mainly used for batch The production of optical lenses with a diameter of less than 100 mm can also produce micro-lens arrays. [0003] To manufacture optical lenses by injection molding, firstly, the quantitative optical plastic that has been heated into a fluid is injected into the mold, then molded under heating and pressure conditions, and finally the mold i...
