Description
Technical field:
The utility model relates to a kind of stereoscopic sculpture electrotyping forming mould, and especially a kind of advantage that keeps the split electroforming, processing be time saving and energy saving, reach 100% stereoscopic sculpture integral electroforming particular manufacturing craft with the grand master pattern similarity.
Background technology:
In the past, no matter for the metal carving product is that " pyrogenic process " casting technique is all adopted in plane embossment or three-dimensional circular engravure, promptly metallic substance is fused into liquid, again molten metal is poured in the high refractoriness of ready-formed, the high-intensity casting mold, treat to remove casting mold again behind the molten metal cooling forming, form through repairing and precision work.Mainly there is following shortcoming in " pyrogenic process " casting technique:
1. Metal Melting not only needs heat energy, but also need intensified ventilation equipment with the large quantity of exhaust gas (flue gas of coke-fired furnace, gas furnace or oil oven that produces in the heat-processed, the gas that part metals and fusing assistant gasification are produced) be disposed in the air waste lot of energy;
2. make casting mold process complexity, the casting mold that has also will take off cured, high-temperature roasting reinforcement through heating, and severe operational environment is unfavorable for environmental protection;
3. need the salvage of casting and finishing step after the casting, need to be equipped with welding machine, welding gun, cutting machine, polishing machine, polishing machine and decorative pattern and to bore instrument at quarter etc., waste time and energy, the tooling cost height;
Since make wax-pattern, metal liquid becomes solid by liquid and the high temperature firmware all can produce dimensional contraction when being cooled to room temperature, foundry goods is through dimensional contraction repeatedly, not only may be obstructed and produce distortion, and size also will be less than the grand master pattern size because of contraction, lower with the similarity of grand master pattern.
There is above problem owing to produce the metal carving product with " pyrogenic process " casting technique, people again utility model electrotyping forming method (electrocasting): promptly make former with insulating material, simultaneously coat electro-conductive material (conductive resin, graphite etc.), extraction electrode (negative electrode) at former; Make anode with formed material metal (copper, gold and silver etc.), anode surface area is 1.5～2: 1 with the ratio of former conductive layer area.Add electrolytic solution in electrolyzer, (current control is at 1～10A/dm with negative electrode, anode and power supply
2) join.Anode metal loses electronics and becomes metal ion and enter in the electrolytic solution, electronics then flows to the former conductive layer, and metal ion deposits to atomic condition behind former conductive layer place electron gain that (quiet thickness was directly proportional with the energising electroforming time), the demoulding get final product on the former conductive layer surface.Electrocasting is compared with " pyrogenic process " casting, though have advantages such as save the energy and material, improve work situation, reduce labour intensity, size is consistent with grand master pattern, but owing to be subjected to the ratio of anode surface area and former conductive layer area is 1.5～2: 1 restriction, existing electrocasting can only once shaped processing plane relief sculpture products or split processing stereoscopic sculpture, i.e. split electrocasting.
The split electrocasting needs earlier three-dimensional grand master pattern to be divided into the tabular former of polylith, is processed into one by one behind the corresponding split foundry goods again that bedding-in, assembly welding become whole stereoscopic sculpture, exists following shortcoming:
1. operations such as burst, bedding-in and assembly welding are various, not only waste time and energy, long in time limit, and easily produce distortion;
2. the decorative pattern that is in assembly welding weld bond, commissure is destroyed, and is essential through hand finish, is difficult to reach 100% with the similarity of grand master pattern.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem that prior art exists, provide a kind of keep split electroforming advantage, processing time saving and energy saving, reach 100% stereoscopic sculpture integral electroforming mould with the grand master pattern similarity.
Technical solution of the present utility model is: a kind of stereoscopic sculpture integral electroforming mould is characterized in that: be provided with the former that stereo hollow, upper opening and inwall scribble conductive layer, be provided with the conductive electrode that joins with conductive layer at the former opening part; Be provided with the three-dimensional conformal anode that can place the former inner chamber, the spacing between described three-dimensional conformal anode outer surface and the conductive layer is 1～7cm, and three-dimensional conformal anode outer surface is that the long-pending ratio with the conductive layer area of corrugated and outer surface is 1.5～2: 1.
Described three-dimensional conformal anode is to twine the wire that one deck diameter at least is not less than 2cm on skeleton.
Outside described three-dimensional conformal anode, be provided with the insulation limited post.
The difference of the maximum of the utility model and prior art is can disposable integral electroforming stereoscopic sculpture, not only have advantages such as the split electroforming is saved the energy and material, improves work situation, reduced labour intensity, size is consistent with grand master pattern, simultaneously also because of need not with operations such as grand master pattern burst, bedding-in and assembly weldings, process time saving and energy saving, shorten the processing duration greatly, because of not having weld bond, weld seam, the decorative pattern of grand master pattern does not just have destroyed, and solid casting and grand master pattern similarity can reach 100%.
