Embodiment

[0036] refer to figure 2 , a specific embodiment of the mold core for glass molding of the present invention, comprising: a tungsten carbide substrate 2, an intermediate film 3 formed on the substrate 2, and a protective film formed on the intermediate film 3 4.

[0037] The intermediate film 3 has an amorphous layer 31 , a first mixture layer 32 , a second mixture layer 33 , and an amorphous carbon layer 34 in sequence from the substrate 2 to the protective film 4 . The amorphous layer 31 has a first side 311 connected to the substrate 2 , and the amorphous carbon layer 34 has a second side 341 connected to the protective film 4 .

[0038] The amorphous layer 31 is a 10nm thick amorphous silicon layer (amorphousSi layer) made by sputtering. Its preparation method is, at 350°C and 5×10 -4 Under the background pressure (base pressure) of Pa, argon gas (Ar) was introduced to reach 3×10 -1 After a working pressure of Pa, a 99.999% high-purity silicon target is used for depos...

Abstract

The present invention discloses mold core for molding glass, and the mold core includes base material, intermediate film formed on the base material and protecting film on the protecting film. The protecting film has one molding surface far from the base material for molding. The intermediate film has one first side connected to the base material and one second side connected to the protecting film and contains C, N and M, where M consists of Si, Ti, Al, W, Ta, Cr, Zr, V, Nb, Hf and B and has content gradually decreased from the first side to the second side.

Description

technical field [0001] The invention relates to a molding core, in particular to a molding core for glass molding. Background technique [0002] refer to figure 1 A mold core generally used in glass molding includes a base material 11 and a protective film 12 formed on the base material 11 . The protection film 12 has a forming surface 121 away from the substrate 11 . The glass material 13 contacting the forming surface 121 is pressed under a high-temperature molding environment to form an optical function surface 131 complementary in shape to the forming surface 121 on the glass material. [0003] The protective film formed on the base material of the mold core for glass molding must be difficult to react with the base material and be made of a composition with good chemical stability. Therefore, the protective film formed on the substrate earlier is made of a diamond-like carbon (Diamond-Like Carbon; DLC for short) film. Although the DLC has good release efficiency, af...
