Abstract
A printing nickel screen improvement mould is provided with a cylindrical mould substrate with two closed ends, and the outer surfaces of the substrate is plated with a copper layer; the surface of the copper layer is pressed with screen dots; the surface of the cooper layer between the surfaces of the screen dots and the surfaces of the gaps of screen dots is plated with a nickel layer; the improvement mould is characterized in that: the surface of the nickel layer is plated with a hard chrome layer which improves the hardness, wear resistance and corrosion resistance of the mould, prolongs the service life of the mould and reduces the production cost; and as the hardness and the wear resistance of the mould are improved, the stability and uniformity of the dimension of the nickel screen are improved.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of printed nickel net mould.
Background technology
Existing printed nickel net mould only is coated with copper layer and nickel dam, because the hardness of nickel dam is lower, its anti-wear performance is relatively poor, so the service life of mould is shorter, has increased production cost.Because the mould anti-wear performance is relatively poor, makes the dimensional stability of its nickel screen of making and uniformity also relatively poor, can influence the quality of stamp.
Summary of the invention
The utility model provides a kind of printed nickel net improvement mould, and purpose is to solve the prior art problem, and a kind of hardness that can improve mould is provided, and is wear-resisting, the printed nickel net mould of corrosion resistance.
The utility model technical scheme that adopts of dealing with problems is:
Printed nickel net improvement mould, the cylindrical die matrix with closed at both ends, outer surface of matrix is coated with the copper layer, and the pressure rolling of copper laminar surface has the site, and the copper laminar surface between surface, site and gap, site is coated with nickel dam, and described nickel dam surface is coated with hard chromium layers.
The beneficial effects of the utility model: be coated with hard chromium layers on the mould, improved hardness, wearability and the corrosion resistance of mould, prolonged the service life of mould, reduced production cost.Through practice, the average system net amount of every mould is brought up to 3450 by 1000.Because the hardness of mould improves, wearability has improved nickel screen size stability, uniformity after improving.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is an A-A cut-away view among Fig. 1
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, printed nickel net improvement mould 10, cylindrical die matrix 1 with closed at both ends, matrix 1 outer surface is coated with copper layer 2, the 2 surperficial pressure rolling of copper layer have site 3, and copper layer 2 surface between 3 surfaces, site and gap, site are coated with nickel dam 4, and described nickel dam 4 surfaces are coated with hard chromium layers 5.
Its production process is earlier die matrix 1 to be put into copper tank liquor copper plate 2, at copper layer 2 surperficial pressure rolling online point 3, mould is put into nickel tank liquor nickel coating 4 then again, mould is put into chromium tank liquor hard chrome plating layer 5 at last again.
Be coated with hard chromium layers 5 on the mould, improved hardness, wearability and the corrosion resistance of mould, prolonged the service life of mould, reduced production cost.Through practice, the average system net amount of every mould is brought up to 3450 by 1000.Because the hardness of mould improves, wearability has improved nickel screen size stability, uniformity after improving.
