Abstract
The utility model discloses a kind of negative plate of improved type electric casting device, comprise substrate, described substrate is made up of epoxy resin board, and epoxy resin board tool heatproof is moisture resistance, and smooth not yielding, non-conductive and quality is light, crash-proof feature; Described substrate pastes the conductive metal sheet that thick layer is about 0.1mm, conductive metal sheet upper end edge is provided with one piece of T-shaped copper coin, and push down with seven primary screws and be fixed on conductive metal sheet, as current-carrying part, upper end edge and the T-shaped copper coin of described conductive metal sheet are coated with acid and alkali-resistance material layer.The utility model advantage is compared with prior art: the negative electrode version weight ratio titanium plate of the utility model improved type electric casting device and stainless steel plate are all wanted gently, handled easily; Impact resistance, does not have upper end edge breakage and enters plating solution and plate out coating, waste the situation of raw-material phenomenon; Failure rate is low, saves human and material resources used when keeping in repair, and the version that electroforming goes out, the space of a whole page is smooth, and the operation of convenient lower operation, improves quality product.
Description
Technical field
The utility model relates to electroforming apparatus, particularly relates to a kind of negative plate of improved type electric casting device.
Background technology
The ultimate principle of electroforming is using the grand master pattern made by desired shape in advance as negative electrode, with electroforming material as anode, together puts into the metal salt solution identical with anode material, passes to influent stream electricity.Under electrolytic action, grand master pattern is separated, thus obtains the metal duplicate corresponding with grand master pattern shape.
Laser holographic plate-making negative plate used is generally titanium plate or the stainless steel plate of conduction.In electrochemistry, titanium is check valve shaped metal, and current potential is very negative, and usual titanium as anode, and can not decompose, can the corrosion of acid and alkali-resistance, and lightweight, easy handling, but expensive, and cost is too high.And stainless steel is relatively lower than titanium plate price, but stainless steel quality weight, be unfavorable for operation, and the corrodibility of acid and alkali-resistance is more weaker than titanium plate, easily generates metallic impurity and enter plating solution.
The negative plate made of titanium plate and stainless steel plate all can have slight arc at more than 800mm*1000mm area, unfairness.Sticking the nickel version of 700mm*900mm area, when being placed on electroforming in casting groove, muscle unfairness is played because hydraulic pressure effect makes to cast out in the middle of next nickel version, the planeness of product is more affected when electoformed product repeatedly, and high to the flatness requirement of nickel plate when postorder embossed holographic, if cast nickel version injustice and adjust and can have a strong impact on quality product.
Negative plate is made with titanium plate and stainless steel plate; do not need the back side of place and the negative plate conducted electricity; with the rubber belt sealing of acid and alkali-resistance; in a large amount of process used, negative plate upper end edge often can be subject to clashing into damaged, manyly when maintenance negative plate also wastes material, and enters plating solution after breakage; coating is cast out during work; waste starting material, discharge metallic impurity in addition, pollute the danger of casting liquid.
Utility model content
The utility model is to solve above-mentioned deficiency, provides a kind of negative plate of improved type electric casting device.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of negative plate of improved type electric casting device, it is characterized in that: comprise substrate, described substrate is made up of epoxy resin board, epoxy resin board tool heatproof is moisture resistance, and smooth not yielding, non-conductive and quality is light, crash-proof feature; Described substrate pastes the conductive metal sheet that thick layer is about 0.1mm, conductive metal sheet upper end edge is provided with one piece of T-shaped copper coin, and push down with seven primary screws and be fixed on conductive metal sheet, as current-carrying part, upper end edge and the T-shaped copper coin of described conductive metal sheet are coated with acid and alkali-resistance material layer.
Further, described conductive metal sheet is the titanium plate of thick about 0.1mm, or stainless steel plate, or substandard products nickel plate.
Further, described primary screw is the screw of pure stainless steel.
Further, described acid and alkali-resistance material layer is adhesive tape or Electropolating hangers special adhesive.
The utility model advantage is compared with prior art: the negative electrode version weight ratio titanium plate of the utility model improved type electric casting device and stainless steel plate are all wanted gently, handled easily; Impact resistance, does not have upper end edge breakage and enters plating solution and plate out coating, waste the situation of raw-material phenomenon; Failure rate is low, saves human and material resources used when keeping in repair, and the version that electroforming goes out, the space of a whole page is smooth, and the operation of convenient lower operation, improves quality product.
