Problems solved by technology

Diamond-like carbon film (DLC) is difficult to achieve a satisfactory mold core life, and precious metals or precious metal alloys have strong chemical stability, sufficient hardness and high temperature resistance, but due to the adhesion between the precious metal protective film and the substrate Poor performance, which greatly reduces the service life of the mold core and indirectly increases the cost of molded glass

Abstract

This invention relates to the glass mould kernel for die casting. It consistes of: a basic layer, a medium layer and a protective film. The basic layer is covered by aid medium layer, and the protective film is over the medium layer. Said protective film has the surface with a trough. The basic material is made of boron carbonitride, and the medium layer is made of non-crystalline carbonitrides. This invention provides also a method for manufacturing said product.

Description

technical field [0001] The invention relates to a molded glass device, in particular to a molded glass core and a manufacturing method thereof. Background technique [0002] With the development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. While people are pursuing miniaturization of digital cameras and video cameras, they also put forward higher requirements for the image quality of the objects they shoot. The image of the object is clear, and the image quality of the object depends to a large extent on the quality of the optical components in the digital camera. [0003] Aspheric lenses are indispensable optical components in digital cameras, and existing digital camera aspheric lenses are made by molding. Since glass molding needs to be carried out at high temperature (about 600°C) and high pressure (10-30KN), the production of aspheric lenses by molding method requires a strictly designed mold core, whic...
