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

Embodiment Construction

[0021] combined reference figure 1 As shown, the molded glass mold core of the present invention includes a substrate 1 and a protective film 2, wherein the protective film 2 is located on the substrate 1, the protective film 2 has a molding surface 21 for molding grooves, and the material of the substrate 1 is Ceramic material, the material of this protective film 2 is fullerene (Fullerene, such as C 60 or C 70 ).

[0022] The method for manufacturing the molded glass core comprises the following steps:

[0023] Provide a substrate 1 of ceramic material;

[0024] A protective film 2 of a fullerene material is deposited on the surface of the substrate 1 .

[0025] The ceramic material is tungsten carbide, silicon carbide, silicon nitride or boron carbonitride. The fullerene material can be prepared by the graphite arc discharge method, and then the fullerene is plated on the surface of the substrate 1 by the ion beam evaporation method, and the thickness of the protective...

Abstract

The present invention is mold core for molding glass and its making process. The mold core includes base and protecting film on the base and with one notched molding surface. The protecting film is made of fullerene, which is prepared through graphic discharge process and is plated onto the surface of the base material through ion beam evaporation process. The base is made of ceramic material, including tungsten carbide, silicon carbide, silicon nitride, boron carbonitride, etc.

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] Aspherical lenses are indispensable optical elements 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, ...
