Abstract
A recycling equipment for an investment pattern comprises a working tank capable of containing recycling liquid and a recycling device, wherein the bottom or four walls of the working tank are provided with a heating device heating the recycling liquid, and the recycling device is located at the upper portion of the working tank and is close to the lower surface of the recycling liquid to recycle a wax pattern heated into a melting state. The recycling equipment for the investment pattern utilizes the characteristic that the wax pattern has fluidity under high temperature, adopts a method of heating the liquid to evenly heat the wax pattern to obtain a fluidic wax body and enabled the wax body to be separated from a complex casting cavity, and then the wax body is recycled. A method and the equipment are simple, convenient to operate and small in environment pollution and can recycle the wax body to the maximum limit.
Description
Technical field
The present invention relates to casting field, particularly about the extraction element of wax-pattern in the model casting.
Background technology
Full form casting process comprises: be casting die through adopting wax-based material at first, then through applying refractory material on it, the wax-based material circulation reclaimed to form the casting cavity again.Therefore wax-type material in whole casting process for recycling.
The complete cycle of wax-type material reclaims the inside dimension that has determined cavity, and and then the quality of decision foundry goods, therefore need circulation comparatively completely to reclaim the casting die that wax-based material forms; , circulation also to consider the distortion of the formed mold cavity of refractory material and come off, peel off phenomenon that the destruction of mold cavity material also directly has influence on the quality of foundry goods when reclaiming wax-pattern simultaneously.
Summary of the invention
For solving the problems of the technologies described above; The present invention provides a kind of receiving unit that loops back of fusible pattern; It comprises: the work nest that can hold the circulation withdrawal liquid; Said work nest bottom or wall are provided with the heater that said circulation withdrawal liquid is heated, and are positioned at the top of said work nest and near the receiving apparatus that loops back of the lower surface of circulation withdrawal liquid, reclaim the wax-pattern that is heated to form molten state with circulation.
This creation utilizes wax-based material at high temperature to have mobile characteristics, adopts the mode of liquid heat that it is evenly heated, and with the wax body of acquisition fluid, and from the casting chamber of complicacy, breaks away from, and then its circulation is reclaimed.This method, equipment is simple, easy to operate, environmental pollution is little, and the recovery wax body that can circulate to greatest extent.

Fig. 1 is the structural representation of first embodiment of this creation;
Fig. 2 is the structural representation of second embodiment of this creation;
Fig. 3 is the vertical view of second embodiment of this creation;
Fig. 4 is the method for using flow chart of this authoring apparatus.
The specific embodiment
This creation provides a kind of receiving unit that loops back of fusible pattern.In conjunction with structural representation and method for using flow chart flow chart Fig. 4 of first embodiment of this creation shown in Figure 1, since the structure of this creation once is described.This creation has disclosed a kind of receiving unit that loops back of fusible pattern; It comprises: the work nest 2 that can hold circulation withdrawal liquid 1; Said work nest 2 bottoms or wall are provided with the heater that said circulation withdrawal liquid 1 is heated; And be positioned at said work nest top and near the lower surface of circulation withdrawal liquid loop back receiving apparatus 7, reclaim the wax-pattern 4 that is heated to form molten state with circulation.
In first embodiment of Fig. 1, the heater that is had in the work nest 2 is: said heater comprises: be arranged in the said work nest 2 gas outlet 5 and from the heated air 6 of the said circulation withdrawal liquid 1 of said gas outlet 5 direct directives.In this embodiment, heated air 6 is generally steam, through heat cycles withdrawal liquid 1 from bottom to top, makes circulation withdrawal liquid 1 heat up, and through water-bath heating and fusing wax-pattern 4.Simultaneously in an embodiment, also have the receiving apparatus of looping back 7, reclaim with circulation and be fused into liquid wax-pattern 4.In diagram, heater is positioned at the bottom of work nest 2, heated air 6 bottom-up heat cycles withdrawal liquid 1, and certain described heater also can be arranged on the wall of work nest 2, with the intensification from a plurality of angles and position quickening circulation withdrawal liquid 1.Simultaneously; Looping back the position of receiving apparatus 7 in work nest 2 is to determine with the density relationship between the wax-pattern 4 according to circulation withdrawal liquid 1; When adopting water as the circulation withdrawal liquid; The position that loops back receiving apparatus 7 is positioned at the higher position place that is arranged in work nest 2, is beneficial to circulate reclaim the less wax-type material of density, for example is positioned at the top of work nest 2 and near the lower surface of circulation withdrawal liquid 1.
According to method for using shown in Figure 4 be:
Circulation withdrawal liquid 1 is provided.The selection main reference of circulation withdrawal liquid 1 its with the mutual solubility between wax-pattern 4 materials, casting cavity 3 materials and the factor of corrosion failure degree; And the parameter of different fusing points and boiling point, with the thorough and environmental protection that guarantees in the circulation removal process protection and the circulation of casting cavity 3 to be reclaimed.For example can adopt water as circulation withdrawal liquid 1.
The work nest 2 that can hold circulation withdrawal liquid 1 is provided.Work nest 2 should have bigger volume, reclaims with the placement of completion workpiece and the circulation of automation.
The casting cavity 3 that will contain said casting wax-pattern 4 places said work nest 2.Can utilize automation equipment to place relevant workpiece, and accomplish circulation recovery back taking-up workpiece.
Circulation withdrawal liquid 1 heating in said work nest 2.The mode of water-bath heating is adopted in this creation, obtaining uniform heating, and the wax-pattern 4 of molten state is realized separating completely with casting cavity 3.
Provide to loop back receiving apparatus 7, reclaim with circulation and be fused into liquid wax-pattern 4.The wax-pattern 4 that loops back the molten state of receiving will contain certain circulation withdrawal liquid 1.Need the follow-up separation of further carrying out with circulation withdrawal liquid 1.
What Fig. 3 and Fig. 4 showed is second example structure of this creation, and in this embodiment, said heater is the heating tube 8 that is arranged in the said work nest.And said heating tube is a hollow tube, and it can be that internal placement has the electrical heating medium; Or be furnished with heated air in the said heating tube 8, steam for example.Adopt the heater of heating tube 8, can avoid among first embodiment, when a large amount of steam directly got into the circulation withdrawal liquid, the disturbance that is produced and to the impact of casting cavity 3 surfaces and internal structure had guaranteed the architecture quality of cast cavity 3.Simultaneously, adopt heating tube 8, also be convenient to arrange and circulation reclaimed all even scalable of liquid heat.Quality and efficient that whole circulation reclaims can both be guaranteed and improve.
The embodiment that is disclosed among the present invention will obtain embodying and protection through claim, any according to the present invention in resulting enlightenment, among the scope that all falls into the present invention and protected.
