Embodiment Construction

[0010] refer to figure 1 , a kind of mold that is used for CD cooling with anti-rust coating provided by the present invention is based on the original mold body 1 used for CD cooling, and adds anti-rust coating 3 on the inner wall of water channel 2, and the anti-rust coating 3 is a composite solder of Ni, Cr, Si, B, with Ni as the main matrix, so that it has good anti-corrosion and anti-rust properties, and the addition of Si and B elements is to reduce the melting point of Ni in the process of production, and The addition of Cr element is considered to increase the oxidation resistance of the solder. The anti-rust coating 3 is covered on the inner surface of the water channel 2 through process operation, and heat treatment process is performed while covering, and the anti-rust coating 3 can be subjected to secondary processing.

[0011] The mold for optical disk cooling of the present invention has an anti-rust coating 3, which does not rust when in contact with water and ...

Abstract

The invention discloses a mould with an antirust coat for cooling an optical disc. The mould with the antirust coat for cooling the optical disc consists of a mould body. A waterway of the mould is accompanied by the antirust coat. The antirust coat not only can prevent generation of scale and rust, but also improves the disc yield and the stability in use greatly due to the excellent heat conductive performance. Hardness of the coat effectively protects the original mirror surface basal body.

Description

technical field [0001] The invention relates to a mold for cooling an optical disk, in particular to a cooling mold for an optical disk with a novel anti-rust coating on the water channel. Background technique [0002] In actual production, optical discs have high requirements on the flatness of the disc, which requires that the cooling system of the optical disc mold is very uniform, and the temperature cooling process on the surface of the forming mirror surface should be uniform and the cooling speed should be fast. After the mold is transported by water, scale or rust often results in local heat transfer defects or rust cracks, which is very unfavorable to the cooling effect of the mirror surface and the service life of the mirror surface. After the mold has been used for a period of time, the finished product yield of the disc begins to decline, and the stability of the mold also decreases. Contents of the invention [0003] In order to overcome the deficiencies of t...
