Description
Technical field
The present invention relates to a kind of manufacture craft of decorative art, particularly a kind of method for making hollow artworks.
Technical background
Chinese patent " a kind of moulding process of making comparatively large vol hollow metal the workmanship " (patent No.: ZL97103571.7) disclose a kind of technical scheme: artwork is separated into several " sub-units ", the material of each " sub-unit " is terne metal, and form with centrifugal casting by rubber mold, after will owning " sub-unit " at last and welding together the integral body that is combined into workmanship, carry out post-processed (for example: polishing, coating etc.) again.
There is following several weak point in this technical scheme: owing to need to make through over-segmentation the process of sub-unit recombinant welding, processing step complexity; Must have certain thickness to achieve to cut apart and make up, therefore, the thickness of terne metal is thicker, and the weight of workmanship is heavier; The intervention of casting method for centrifugal has limited the application of material, generally can only use terne metal, can not satisfy the demand of workmanship market to changes in material.
Existing casting technique product technology: a kind of sophisticated investment casting method commonly used, it makes wax-pattern with wax material, cover type shell material outside wax-pattern, after treating that shell solidifies, after the heat fused wax-pattern is sloughed wax, obtain the die cavity in the shell, again the casement chamber suitable alloy of casting is promptly got the foundry goods of artwork.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing step simple, and be suitable for large-scale industrialization and use, and the thin again method for making hollow artworks of the hollow artworks wall thickness that is obtained.
The present invention is achieved through the following channels.
Method for making hollow artworks, comprise the steps: to provide a kind of wax-pattern, this wax-pattern is a kind of formpiston, a kind of electrochemical depositer is provided and adds the electrochemistry plating bath, wax-pattern is put into the electrochemistry plating bath case of electrochemical depositer, start this electrochemical depositer, after acquisition covers the electrodeposition cladding on wax-pattern surface, take out this galvanic deposit plating piece and on this plating piece, obtain the dewaxing passage, a kind of dewaxing device is provided, this galvanic deposit plating piece is put into this dewaxing device dewax, the galvanic deposit plating piece of collecting after dewaxing is hollow artworks.
Electrochemical depositer and electrochemical deposition method are a kind of proven technique, and obtain to widely apply in industry.Yet, in the routine techniques only with it as provide the coating of protection to use for machinery part surface, never the core body of wanting to allow this coating and being plated breaks away from and becomes independently member, on the contrary, but how can rack one's brains with more firm the contacting of the core body that is plated for this coating always.
The present invention is an anti-convention but, not only selects nonrigid material (wax) as the core body that plated, and do not consider the coating contact firmly and the most at last it breaks away from the core body that is plated, more and also with the coating body as independent member.
This electrochemical deposition can be that electrochemistry has galvanic deposit, also can be the electrochemistry electroless deposition.
The present invention can also realize by following approach.
The thickness of electrodeposition cladding is greater than 0.1mm.
Electrodeposition cladding is too thin, and is crisp easily broken, and also sends out wrinkle in dewaxing process easily because of expanding with heat and contract with cold.Yet,, also can too increase the time of galvanic deposit and production cost is strengthened if too thick.Therefore,
The thickness of electrodeposition cladding is ideal at 0.1mm～1mm.But best thickness range is 0.2mm～0.7mm.
A kind of tree-shaped instrument and a kind of wheelwork hung is provided, this instrument is installed in the electrochemistry plating bath case, and allows this instrument and wheelwork be in transmission connection, a plurality of wax-patterns are hung on this instrument, start again and carry out electrochemical deposition.
Like this, not only conveniently carry out galvanic deposit, and can obtain electrodeposition cladding uniformly.
In the acquisition mode prior art of wax-pattern a large amount of introductions are arranged, yet what relatively be suitable for the present invention's application is:
A kind of rubber model is provided, and this rubber model is a kind of former, the wax-pattern raw material is put into this former obtain wax-pattern by die mould.
Owing to be used for industrialized scale operation, mass-producing that must be extremely easy obtains wax-pattern, and rubber model can satisfy this requirement undoubtedly as the intervention of producing mould, and, the acquisition of rubber model be easy to and also its material cost cheaper again.
Described electrochemical deposition can be that galvanic deposit is arranged also can be the electrochemistry electroless deposition to electrochemistry.
When galvanic deposit being arranged for electrochemistry, should be earlier after conductive coating be brushed on the wax-pattern surface, putting into electrochemistry again has the electrochemistry plating bath case of electric deposition device that galvanic deposit is arranged.
Conductive coating can be the silver slurry, also can be the copper slurry, can also be gold paste or tin slurry, yet selecting preferably is silver slurry or copper slurry.
So-called dewaxing passage is meant that the electrodeposition cladding surface has open-work, and during for the dewaxing operation, melt and dissolved wax is reserved the passage of deriving.Therefore,
The institute of hollow artworks inherent open-work own can be used as this dewaxing passage;
When hollow artworks itself does not have this open-work, should on electrodeposition cladding, make this process channel, conventional production method can be in more hidden position boring.Yet,
When galvanic deposit being arranged for electrochemistry, can reserve a zonule of not brushing conductive coating on the wax-pattern surface, like this, coating can not obtain the dewaxing passage in this place's deposition.
The selection of dewaxing device has multiple, be fit to be applied in and of the present inventionly be: a kind of hot water heater with big cavity is provided, cavity top has a kind of overflow channel, topped up with water in this cavity, the galvanic deposit plating piece is put into this cavity carry out boiling, the wax of deriving from the dewaxing passage swims in the water surface and discharges and collect from overflow channel.
The wax of collecting can recycling.
Galvanic deposit plating piece after the dewaxing can carry out surface treatment.The surface-treated operation can be polishing; Can be first polishing also, electroplate again, thereby cover one deck coating again at the galvanic deposit plating piece.
This coating can be conventional electrolytic coating, also can be the coating of electrochemical deposition, and when this moment, galvanic deposit plating piece of the present invention can obtain by electrochemical deposition repeatedly.
Generally, sedimentary once more thickness is less than last sedimentary thickness.
Generally speaking, obtaining to repair processing to it earlier behind the wax-pattern, then carry out electrochemical deposition again.
In sum, the present invention has following advantage compared to existing technology: processing step is simple, is suitable for large-scale industrialization and uses, and almost can arbitraryly approach behind the wall of hollow artworks, simultaneously, has splendid surperficial sophistication again.
