(4) will be through soaking in the LMP alloy product immersion water of eliminating the space;
(5) use≤5 kilograms low pressure water to wash away the gypsum that has dissolved in the LMP alloy product then, become the inner wall shape alloy hollow mould the same with the soluble plasters mould shapes;
(6) the alloy hollow mould is placed in the container that iron and steel makes, the outer wall of alloy hollow mould and iron and steel are made between the inwall of container alkaline electrolyte are housed, and the inwall cavity of alloy hollow mould adds acid electrolyte;
(7) with add in the porous stainless steel with product material same metal rod or metal block as anode, carry out in the bipolarity metals such as copper electroforming, zinc to wall thickness more than 0.1 millimeter with the alloy hollow mould as negative electrode;
(8) alloy hollow mould and electroforming metal hollow goods in it go out to immerse behind the shell and moltenly in the solution that is higher than the molten point of alloy remove outer formwork, obtain the metal hollow goods of any surface finish thus.
Purpose of the present invention can also reach by following measure: alkaline electrolyte can be a sodium hydroxide, and acid electrolyte can be the acid electrolyte with the casting material same metal.
Purpose of the present invention can also reach by following measure: low melting point alloy contains 55%(weight) bismuth, 45%(weight) lead.
Purpose of the present invention can also reach by following measure: soluble plasters contains 8%(weight) Zulkovsky starch, surplus is common semi-hydrated gypsum.
Purpose of the present invention can also reach by following measure: the wall thickness of metal forming metal hollow goods such as copper electroforming, zinc can be 0.3～0.5 millimeter in the bipolarity.
Purpose of the present invention can also reach by following measure: the special character of making the specific equipment of metal hollow article process is: the container that it can be made by iron and steel, the insulation cover plate of container head, pass insulation cover plate and place the interior alloy hollow mould of container, place the stainless steel anode of alloy hollow mould inside, with the interior electrolysis tube that the stainless steel anode end is connected, the electrolyte inside of alloy hollow mould tail end suit overflows to manage and forms.
The present invention has following advantage compared to existing technology: improved dark plating, throwing power, with low cost, operating procedure is simple, and the material of alloy hollow mould can use repeatedly.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the used production unit of metal hollow goods bipolarity inner electric mould forming method.
The present invention will now be further detailed embodiment:
As shown in the figure, utilize the plastics soft mode that turns over the system plaster statue on the market to turn over and make the soluble plasters model, soluble plasters is by containing 8%(weight) Zulkovsky starch, surplus is that common semi-hydrated gypsum is formed.The soluble plasters model through thorough oven dry back is 1.5～2.5 millimeters low melting point alloy coating at its outside surface spraying wall thickness, and low melting point alloy is by containing 55%(weight) bismuth and 45%(weight) lead elementary composition, its fusing point is 124 ℃.Spray gun can adopt the transformation of the way of plain metal spray gun, and additional self-control metal fusion pot is used.After the low melting point alloy coating forms, article outer surface after spraying is eliminated the sandblast in space, to immerse through the LMP alloy product of eliminating the space in 60 ℃～80 ℃ the aqueous solution and soak 30 minutes, water with 0.1 MPa pressure washes away the gypsum that has dissolved in the low melting point alloy goods then, dry just become have electroconductibility, alloy hollow mould that inner wall shape is the same with the soluble plasters mould shapes.Above process is the manufacturing processed of low melting point alloy formwork.Alloy hollow mould placed container 1 that circular steel iron make in, just can carry out the process of bipolarity electrode inner electric mould forming metal hollow goods thereafter.This specific equipment that is provided with for this method of forming, the container of making by iron and steel 1, container 1 vertical insulation cover plate 2, pass insulation cover plate 2 and place alloy hollow mould 3 in the container 1, place the stainless steel anode 4 of alloy hollow mould 3 inside, with the interior electrolysis inlet pipe 5 that stainless steel anode 4 ends are connected, the electrolyte inside of alloy hollow mould 3 tail end suits overflows and manages 6 compositions.The process of narration bipolarity electrode inner electric mould forming metal hollow goods below: alloy hollow mould 3 is placed in the container 1 that circular steel iron makes, the A3 steel steel plate of these container 1 usefulness 2 mm thick is made, and the size in the container 1 is pressed the size of alloy hollow mould 3 and amplified 20～35 mm distance at each single face.The outer wall of alloy hollow mould 3 and circular steel iron are made between the inwall of container 1 sodium hydroxide electrolytic solution 7 are housed.Add the metal acid electrolyte 8 identical in the inwall cavity of alloy hollow mould 3 with casting material.Adding metal bar identical or metal block 9 in the porous stainless steel 4, carry out in the bipolarity metals such as copper electroforming, zinc to 0.3～0.5 millimeter of wall thickness with alloy hollow mould 3 as negative electrode, used for electrolyte pump circulating filtration as anode with product material.Alloy hollow mould 3 and electroforming metal hollow goods 11 in it go out to immerse behind the shell and moltenly in the solution that is higher than 124 ℃ remove outer formwork, again the character pattern that metal hollow goods 11 surfaces are had an exquisite ridge design carry out behind the decorative electroplating bright and glittering, the travel craft souvenir that available for export is earned foreign exchange.These travel craft souvenirs can be made imitation of an ancient bronze, Terracotta warrior, Journey to the West moulding, the Goddess of Mercy, Venus etc. respectively.
