Abstract
The invention discloses an electroforming device of a metal mesh. The electroforming device of the metal mesh comprises an electroforming tank, wherein a metal plate serving as an anode, a core mold serving as a cathode, and a first heating rod are arranged inside the electroforming tank. The electroforming device is characterized in that the metal plate is arranged below the core mold; a second heating rod is also arranged on the core mold; and the cathode core mold is arranged below the metal plate. The density of the electrolyte is reduced due to the large consumption of 'heavy' metal ions of the electrolyte near the lower cathode in an electroforming process; the solution becomes light; a large-density gradient difference is formed between the upper layer and the lower layer of the electrolyte inside the tank; and the 'heavy' electrolyte is 'replenished' downwards while the 'light' electrolyte moves upwards under the effect of gravity, so as to form convection current and improve the mass transfer effect. The second heating rod is also arranged on the core mold; a temperature difference of a certain value is formed by high temperature generated near the cathode and low temperature of the electrolyte when a second work rod works; and the mass transfer effect is further strengthened.
Description
Technical field
The present invention relates to a kind of electroforming apparatus.
Background technology
Electroforming is to utilize the electrolytic deposition principle of metal accurately to copy the physical process method of some complexity or special shape workpiece.Concrete steps be the electroformed mould of making by desired shape in advance as cathode, as anode, together put into the metal salt solution identical with anode material with electroforming material, pass to direct current.Under electrolytic action, electroformed mould shows and deposits the metal plating layer gradually, takes out from solution after reaching required thickness, and electroformed layer is separated with grand master pattern, just obtains the metal replica corresponding with the grand master pattern shape.
Electroforming with wire netting sheet of the little groove structure of big depth-to-width ratio is a critical technological point of present micro processing field.The depth-to-width ratio of considering big thickness fine metal net sheet is bigger, exists serious electric current distribution uneven and cause the limited phenomenon of mass transfer in the micro electroforming process.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of electroforming apparatus that can reduce the limited phenomenon odds of material mass transfer and degree.
For addressing the above problem, the invention provides a kind of wire netting sheet electroforming apparatus, comprise electrotyping bath, also be provided with metal sheet as anode in the described electrotyping bath, as core and first heating rod of cathode, it is characterized in that: described metal sheet is arranged on the below of described core, also is provided with second heating rod on the described core.
As a further improvement on the present invention, also be provided with the temperature sensor of described first heating rod of control in the described electrotyping bath.
As a further improvement on the present invention, also be enclosed with anode on the described metal sheet.
As a further improvement on the present invention, described metal sheet is the nickel plate.
As a further improvement on the present invention, described electrotyping bath is stainless steel, and in be lined with polythene material.
As a further improvement on the present invention, also be provided with transparent access panel above the described electrotyping bath.
Beneficial effect of the present invention is, the cathode core is arranged on the below of metal sheet, the mass consumption of electrolytic solution " weight " metal ion makes this place's density of electrolyte reduce near the negative electrode below being arranged in the electroforming process, solution lightens, it is poor that groove electrolyte inside levels forms big density gradient, and under action of gravity, " weight " electrolytic solution is " enriching " and " gently " electrolytic solution moves upward downwards, form convection current, improve mass transfer effect.And also be provided with second heating rod on the core, during the second work rod work, will make near the temperature head that produces high temperature and electrolytic solution low temperature formation certain numerical value the negative electrode, with reinforcing mass transfer effect to a certain extent.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 1, a kind of wire netting sheet of the present invention electroforming apparatus comprises electrotyping bath 16, also is provided with metal sheet 2 as anode in the electrotyping bath 16, as core 6 and first heating rod 14 of cathode, wherein metal sheet 2 is arranged on the below of core 6, also is provided with second heating rod 8 on the core 6.
Further, also be provided with the temperature sensor 12 of control first heating rod 14 in the electrotyping bath 16.
Temperature is the key process parameter in the micro electroforming technology.Under the constant situation of other conditions, improve the travelling speed that temperature can be accelerated effects of ion, improve the electroconductibility of solution, can also improve dispersive ability and the degree of depth ability of plating bath, coating is evenly distributed; Simultaneous temperature raises, and can reduce cathodic polarization, causes the chap of coating crystalline particle, but can use bigger current density after heating up.Changing other operational conditions such as plating bath ionic concn and current density, and matching coordinative is when suitable, the rising temperature is favourable to the electroforming process, general electroforming process is all selected suitable heating, to increase the solubleness of salt, improve anode dissolution, improve plating bath electroconductibility, reduce the hydrogen-separating quantity of coating etc.In the present invention, the electroforming electrolyte temperature all is set at 25 ℃.When electrolyte temperature was equal to, or greater than 25 ℃, temperature sensor 12 controls second heating rod 8 stopped heating; When electrolyte temperature during less than 25 ℃, 8 work of temperature sensor 12 controls second heating rod are heated to 25 ℃ to electrolytic solution.Make electrolyte temperature maintain 25 ℃ all the time.
Further, also be enclosed with anode 4 on the metal sheet 2.To reduce impurity particle in the solution.
Further, metal sheet 2 is the nickel plate.Adopt metallic nickel because nickel is stable more than iron in air or in malaria, and in air, be easy to form transparent passive film and do not continuing not oxidizedly, can keep constant gloss.In addition, metallic nickel has good plasticity and higher hardness, and the solidity to corrosion of nickel is very stable in organic acid.
Further, electrotyping bath 16 is stainless steel, and in be lined with polythene material be used for the insulation.Not only attractive in appearance but also high temperature resistant.
Further, electrotyping bath 16 tops also are provided with transparent access panel 10.Be convenient to observe the situation in the electrotyping bath 16.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must determine technical scope according to the claim scope.
