Description

Metal fever melts and sprays casting art ware and preparation method thereof

The present invention relates to a kind of art ware and preparation method thereof, particularly melt and spray art ware of casting and preparation method thereof with metal fever.

Background technology

Existing metal art goods generally all are to adopt the method for machined or casting to make, making the metal art goods with casting method has the incomparable advantage of machined on the free degree of moulding, and machined has huge cost advantage with respect to casting in the production of the adequate plastic arts goods of machined.Existing casting method is lower than one millimeter or under one millimeter situation up and down in that the product wall is thin, is difficult to successfully produce the bigger no defective product of moulding area.And make the thin-walled art ware with known existing casting method, its yield rate and cost of manufacture all can not be satisfactory.Most of its wall thickness surpasses one millimeter cast metal art ware, its all inartistic goods self moulding of that part of wall thickness and structure institute that surpasses one millimeter is essential, but for the process limitation of looking after existing casting technique and yield rate and the extra wall thickness that increases.This has caused huge waste of material undoubtedly, and the weight that the art ware of metal casting simultaneously increases because of wall thickness has limited the metal art goods again and has been more widely used in packing and practical implements manufacturing field.

To be controlled at a millimeter to the wall thickness of cast metal art ware even below one millimeter, in traditional casting method, can meet with the bottleneck that is difficult to break through, Here it is, and die cavity is the moulding face of product, is again the contradiction between this dual identity of passage spread of molten metal.Space design as product, the wall thickness of die cavity should be controlled in the scope that satisfies thin-wall metal art ware self modeling requirement, but the passage of spreading as molten metal, die cavity must satisfy the flowability of molten metal in the suitable temperature scope again so that molten metal is spread whole die cavity fluently, realizes whole moulding target satisfactorily.In order to realize these two technology and the technological design targets of conflict to some extent simultaneously, sacrifice some thin in shape-designing pursuit to wall, flow to insulation and increase the requirement of pressure even the requirement of feeding during the foundry goods condensation to cater to molten metal, just become the selection that the conventional cast method has to face.Like this, looked after that molten metal flows and process goal that this conventional cast method of flowing during feeding must be looked after after, for the necessary wall thickness of insulation, supercharging and feeding in most of the cases with the moulding of metal art goods own essential or best wall thickness require irrelevantly, even can damage or partial sacrifice metal art goods moulding original design object aspect wall thickness.

Should guarantee that molten metal flows and put in place, guarantee that again the design object of cast metal art ware on wall thickness fully realized, a known really metal hot melt casting method technical barrier being difficult to take into account.

Summary of the invention

The technical solution adopted in the present invention is, adopt open cast moulding model, make the moulding face of cast metal art ware and the channel separation that molten metal is spread, thereby realize allowing this moulding face only have this process goal of single modeling function, so that allow the cast metal art ware aspect wall thickness, fully satisfy all requirements of art ware shape-designing and consumer's use.

In order to realize this technical scheme better, art ware required cast moulding model in cast metal is open cast moulding model, this cast moulding model mainly adopts the process of outer model model moulding, and the moulding face die cavity of this cast moulding model can fully be admitted the molten metal bath of being sent to by metal spray gun without barrier, thereby realizes the formed product target of being scheduled to satisfactoryly.

Melt and spray the casting art ware in order to make metal fever of the present invention, the method that is adopted is, in advance make the required open type model of casting with machined, craft, casting, the model system of turning over and other process, this type model can be selected a kind of and combination in metal, resin, silica gel, gypsum, pottery mud, quartz sand (powder), kaolin, refractory cement, sodium metasilicate, Ludox, ethyl silicate, paraffin, silicate and other Modeling Material for use according to fire-resistant or nonfireproof various technological requirements.Above-mentioned open type model selects to make the outer model or the interior model of metal casting according to the desired moulding precision of product.After making above-mentioned open type model, select for use known metal thermal spraying equipment and satisfactory metal alloy powders or monometallic powder to finish the target of melt metal powder liquid being sent to product-forming face die cavity with known spraying method.Treat that molten metal is full of the moulding face die cavity of above-mentioned type model and reaches the thickness that condenses of design, take product and type model thereof away, can obtain the metal art goods that the system of casting is finished behind the demoulding or the fusible pattern.

The present invention is described in further detail below in conjunction with accompanying drawing

Fig. 1 is principal section figure of the present invention

As shown in Figure 1, open type model 1 of the present invention is made by a kind of or its combination in metal, paraffin, colliery powder, kaolin powder, pottery mud, gypsum, resin, quartz sand, sodium metasilicate, silicon rubber, Ludox, ethyl silicate or other Modeling Material, has the die cavity 3 that is made of any moulding and decorative pattern of opening on the moulding face of above-mentioned open type model 1.In the moulding face die cavity 3 of open type model 1, be shaped on the cast metal art ware 2 of any wall thickness that can meet design requirement.

Melt and spray the casting art ware in order to make metal fever of the present invention, the specific embodiment is, select a kind of or its combination in metal, modified resin, gypsum, quartz sand, colliery powder, kaolin powder, pottery mud, ethyl silicate, Ludox, sodium metasilicate, silicate or other Modeling Material that can tolerate the metal thermal spraying temperature for use, with machined, craft, casting, the model system of turning over, be coated with the hanging material and other formative method makes open type model 1.This open type model 1 is the outer model of its resultant metal art ware 2 under products made thereby moulding and the complicated meticulous situation of decorative pattern.Allow the moulding and the decorative pattern of above-mentioned open type model 1 moulding face die cavity 3 keep accessible opening; spray after with known metal thermal spraying method and to be cast in the moulding face die cavity 3 of above-mentioned open type model 1 selected self-fluxing nature metal alloy powders or monometallic powder melts; make it in this moulding face die cavity, to form the cast metal layer that adheres to specification; after waiting to obtain needed wall thickness; take open type model 1 away together with the cast metal art ware 2 that has made; behind the demoulding or the fusible pattern, can obtain the metal art goods of design.

Because metal fever of the present invention melts and sprays the technology that the preparation method of ingot metal art ware mainly adopts outer model model type, solve thermal spraying molten metal surface effectively and spread problem inhomogeneous and that spray metal liquid is piled up infringement art ware modeling effect at moulding decorative pattern concave surface, thereby for this traditional handicraft method of metal thermal spraying (metalwork surface peening and defect repair field known method) has been cleared away technology barrier as new molten metal casting method.Adopt the method casting metals foundry goods of fuse metal liquid spraying, fundamentally having solved the insoluble cast moulding pattern of conventional cast method chamber is molder tool or space design, be again the passage that molten metal is cast and spread, the contradiction between the two on technology and design object.This kind of pouring channel and space design separates, and not only makes the cast metal art ware can break through original technology bottleneck aspect wall thickness, allows the casting thin-wall art ware obtain unprecedented development space; And make order casting successively and consecutive solidification become the process that accurately to control, thereby the defective that has caused owing to the feeding deficiency when having avoided conventional cast method casting thin-wall part effectively.

The hot melt spray to cast metal art goods that make thus can be made by needed wall thickness of metal art ware self shape-designing and structural strength thereof, and needn't remove to increase the wall thickness of art ware for the technological requirement that satisfies the conventional cast method extraly.This also for the significantly weight reduction of casting art ware, enters into the field that combines with packing and daily implements and has opened up wide road.
