Abstract
The plastic-coated die mould is to be coated on the art work with plastic paste, behind the heating plasticizing, takes off the former of making original art product apperance so that in former casting system wax-pattern, make art work foundry goods with the follow-up operation of model casting then.
Plastic-coated die mould copy art product have many good qualities: 1, can not open or open less die joint.2, the plastic paste that applies duplicating property is good.3, the female mold surfaces after the plasticizing is bright and clean, guarantees the fineness of wax-pattern.4, the not only reproducible profile that goes out art work complexity, and reproduciblely go out special-shaped inner chamber.5, can apply on the spot for the art work fixing, that can not move and get former.
Description
The present invention is a kind of cast molding new method of copy art product, and main purpose is that copy of ancient for the casting art work, also can be used for the production of single-piece, small lot precision casting.
First critical process of artwork casting is to duplicate raw sample die sinking, and the quality of this process quality will directly influence the moulding and the value of art work foundry goods.The moulding of the gypsum of the many employings of copy art product at present, this method also is used for small lot castings production in the factory.Take off die sinking with gypsum, often, therefore after taking out grand master pattern and casting, take out wax-pattern, have on gypsum mould, offer many die joints because the profile of the art work is very complicated.Make the wax-pattern of local shape for the often first piecemeal of many arts work, assembly welding becomes whole then.The place stays fash at die joint.The vestige that assembly welding stays all needs to repair to scrape, and this has just destroyed the bright and clean naturally of wax-pattern surface, even has destroyed complete floral designs.For the art work that the complicated inner cavity shape is arranged, gypsum mould is powerless especially.
At present, existing abroad human silicon rubber takes off the system former state, adopts the way of upper and lower somatotype.The silicon rubber good springiness makes in the upper and lower type the local place that is difficult to delivery open die joint in addition, and this before goes a step further than gypsum mould.The plastic-coated die mould is before to go a step further again under the inspiration of silicon rubber die mould.
The present invention is coated on the original art work with a kind of plastic mixture cold, and through heating plasticizing, i.e. moulding obtains the former of original art work shape. Fill with wax in this former, obtain wax-pattern, the wax-pattern die mould processed as model casting factory is so be called the plastic-coated die mould. The present invention adopts the proportioning of plastics mixing section to be
80 parts of paste resin (being the plasticized paste resin again)
20 parts of powdered resins
60 parts of dibutyl phthalates
20 parts of dioctyl phthalates
25 parts of dibasicity lead phosphates
1.8 parts of tribasic lead sulfates
1.0 parts of lead stearates
1.0 parts of barium stearates
After above-mentioned material taken by weighing, mix and stir, until the pasty state that forms fusion.The plastics thickener is coated on the original art product that will duplicate with brush or scraper plate, about 1 millimeter of thick coating, the hollow place wants careful brushing, and thickener and original art product are adhered to conscientiously.After the coating this handicraft packed into and heats in the stove, be warming up to 160～180 ℃, be incubated 10～15 minutes, plastic paste is plastified fully till.Repeat above-mentioned coating, heating process 2～3 times, make plastic housing thickness reach 2～4 millimeters.Repeatedly the advantage of Tu Fuing is to make ground floor coating thin, and it is evenly proper to be coated with reactivation.The plasticizing of heating back is thorough, and the coating inner surface that pastes original paper is bright and clean.In addition, repeatedly coating is convenient to supply a gap.Cracks coating is once more arranged, make its fusion.After the plastic paste plasticizing was finished, the plastics die mould was peeled off in the cooling of coming out of the stove then.In general, plastics die mould and original paper are non-caked, peel off to be easy to.Because the high-ductility of plastics, as long as there is not the curve of sealing on the original paper, the plastics die mould can turn over and peel, and does not need to cut out breach, and that is to say does not need die joint.If the handicraft shape is too complicated, before coating, just must think about the position of isolating mouth, so that thicken plastic layer or make lug, clamping when being convenient to irritate wax at this place.During cracking mouthful, the edge of a knife is oblique down or cut out a stairstepping, in case run wax when irritating wax.The plastics die mould does not have and isolates mouthful just directly with the pouring of wax liquid.Wax liquid can be controlled in 60 ℃, and the wax temperature is higher, duplicating property better, the wax-pattern clear-cut.The plastics die mould is if any the place of isolating, to it be cemented with adhesive plaster in advance, or with irritating wax again after the lug clamping of reserving, use water cooling after irritating wax, treat that it solidifies one deck wax shell, pour out unnecessary wax liquid, plastics die mould and wax-pattern are dropped in the water together cool off again, so just make the wax-pattern of a hollow.Turn over stripping plastics die mould then, take out wax-pattern.Last assembly welding cast gate and gate stick are so that carry out the model casting operation.
For the fixing irremovable casting art work, coated plastics die mould on the spot, its heating process solves with electric heater.Heater carries out plasticizing as being placed on art work inside from inside to outside, and the plastics die mould can once be coated onto desired thickness.For the inner chamber complexity, the art work that dark narrow profiled holes is arranged, can at first tamp with the plastic paste pouring, and then be coated with other place, plasticizing back plastics are extracted from endoporus, because of plastics flexible, resilient still after extracting, these plastics are bonded at outer plastic place accordingly, make wax-pattern also can make corresponding endoporus, this is that gypsum mould is helpless.
The present invention also is suitable for making master mold with plaster statue, tri-coloured glazed pottery, clay figurine, stone manufacture, woodwork etc., as long as its material can stand about baking more than 100 ℃, all is applicable to the present invention.After making former, to the master mold not damaged.
The present invention applies former product, and to duplicate property good, with the pouring of high temperature wax liquid, more can obtain the wax-pattern of any surface finish; Decorative pattern is clear, and the hair filament all comes clearly into view.Though the plastics die mould has been isolated out by the part, can close lightly when irritating wax and close finely, flawless, making on the whole wax-pattern does not have fash.No matter how complicated the foundry goods art work all can make whole wax-pattern, do not need piecemeal.And then assembly welding.So both guaranteed the relative position at each position of product, the not bright and clean vestige of having avoided assembly welding to stay again.For the irremovable art work, the present invention also can well duplicate ， And and be applicable to many kinds of materials, has so just opened up the moulding scope of artwork casting.It is short that the present invention makes the wax-pattern cycle, duplicates an art work, takes out wax-pattern from preparing burden to, only needs 3～4 hours altogether.Technology of the present invention is simple, and is easy to operate, and cost is not high.This law also is suitable for the production of small lot foundry goods.
