Description
Technical field
The present invention relates to the method for lost-wax casting under a kind of pressure crystallization condition and the equipment that is used to implement this method.
Background technology
Under the situation of pressure crystallization, be expressed into the method for casting in the mould by patent Nr.2015829 is known by metal, wherein when steel is higher than liquidus line 30 to 60 and spends with melt cast to an extruding cavity in and extruding before when constituting the metallic crystal shell on the wall at extruding cavity, be held.In this method disadvantageously, the solid-liquid that may form melt in the time of in metal remains on extruding cavity mixes phase.Known when liquid phase pressure work best.Pressure validity reduces when the metal that will cool off already is poured in the mould (further crystallization taking place at this mould) by extruding cavity.This may can not meet the cast(ing) surface that quality ground is made the thin portion section of foundry goods and constituted waveform because the loss of thin fluids show as, and perhaps owing to lack when supplying with that liquid phase causes because the error that contraction causes, and obviously influences casting quality generally.
Refer to a method of under the situation of pressure crystallization, carrying out lost-wax casting below according to patent Nr.2048954, the wax-pattern casting mold (Maskenform) of moulding is fixed on the workbench on top of canister top and melt is extruded by means of a push rod before one of them, wherein under the temperature that the alloy crystallization begins and be applied on the melt at 0.3 pressure between 0.5MPa the time begin to extrude, until foundry goods sclerosis, and poring rate and regulating by the mass flow of the melt between 2 to 5kg/s the duration of pouring.
The shortcoming of this known method is the lower intensity of ceramic wax-pattern casting mold, and it is generally used for freely pouring into a mould, and is not used in compression casting.The intensity of wax-pattern casting mold and therefore the operating pressure of maximum possible depend on the material of quantity, application of layer coated when making multiple layers of molds and binding agent, keep condition, casting dimension and casting material, pouring condition and other the core data of operational data, its moulding in the cast container working strictness when making.More difficultly calculate wax-pattern casting mold pressure inside in theory at this, thereby when utilizing casting method to make new product, all need the Asia to leave for the pressure that test is taked at every turn from the actual strength of wax-pattern casting mold.May form micro-crack on mold shell in the manufacture process of wax-pattern casting mold or during its calcining, it can not damage the quality of cast article when freely casting for this reason, but may cause the fracture of mould during compression casting.
By the known a kind of equipment of casting when the pressure crystallization of patent Nr.2116865, it comprises a canister, the arrangement container on workbench that is installed in top on the workbench that is arranged on the bottom, this arrangement container has a wax-pattern casting mold, wherein canister constitutes by a base and a removable cup, a heat insulation layer is set between their bottom, and settles container to constitute by a housing, a cover plate and a neck.In its underpart, has the opening that is used to discharge gas at this removable cup.
In this known equipment disadvantageously, begin to constitute the alloy-layer (metallic crystal shell) of crystallization in the canister on the whole height of back at its sidewall at casting of metals, it stops punch die to move in canister and melt enters in the mould via the neck of settling container, this self may cause defective, as the filling of mould deficiency.In this structure of equipment, the metallic crystal shell works during at melt crystallization after mould is filled melt especially unfriendly, wherein the metallic crystal shell stops during growth on the operating path of punch die and the contraction after the crystallization of foundry goods finishes in canister the metal in the remaining die-casting material is expressed in the mould, to be used to supply with foundry goods.This has damaged the quality of cast article and the advantage of compression casting has been reduced to minimum, acts on because pressure no longer acts on the melt on the metallic crystal shell in the canister.
Summary of the invention
Of the present invention group common technical purpose is, improve the quality of cast article, so that high pressure can be acted on the melt in the wax-pattern casting mold of reinforcing, this wax-pattern casting mold obtains by being reduced at the same time under the situation of the adverse influence of the crystallization process of the metallic crystal shell of canister formation in melt layer that is positioned on its inwall (metal shell) of formation during the crystallization, and described metallic crystal shell prevention is expressed into melt in the wax-pattern casting mold.A common technical result is, when realizing of the present invention group, it relates to a kind of method, this method so realizes, promptly under a temperature that is positioned on the liquidus line and the cavity that under a pressure, melt is expressed into the wax-pattern casting mold of a moulding, at the flow of guaranteeing under the described pressure during wax-pattern casting mold filler to splash in the nothing of the maximum of liquid metals, wherein after filling melt for the wax-pattern casting mold, the pressure in the cavity of wax-pattern casting mold is maintained on the value, reach in the crystallization time of this value melt layer on the wall that abuts in the wax-pattern casting mold when extruding, and and then in the crystallization time of the whole melt in the wax-pattern casting mold pressure is increased to gradually a value, this value is enough to make the amount of contraction of the follow-up filling foundry goods of wax-pattern casting mold.
Common technique effect is so realized at realization device of the present invention, promptly settle the outer surface of the neck of container to be provided with a removable fire-resistant sleeve, and the flange of the annular of a lining is set on the edge that opens wide of the cup of canister, the overall diameter of the interior diameter of this flange and fire-resistant sleeve is suitable, and wherein the interior diameter of the flange of lining is less than the interior diameter of the cup of lining.On radial dimension, surpass the gross thickness of one-sided melt layer in the difference of the interior diameter of the interior diameter of the cup of lining and fire-resistant ring, described melt layer cast and keep when crystallization finishes crystallization already on the wall of the cup of lining with the wall of fire-resistant sleeve on.
These feature groups are for summary of the invention " method " and Yan Shixin's and owing to following reason has the invention practicality.Under the temperature that is positioned on the liquidus line, melt is expressed into the cavity of an in type wax-pattern casting mold, thereby guarantee the contacting of wall of favourable wash and melt and wax-pattern casting mold, so that under the situation that constitutes metallic envelope on the inner surface of wax-pattern casting mold, provide favourable heat transfer conditions.Definite pressure that sets out thus, promptly the liquid metals of casting mold is filled with the speed of a regulation does not have realization with splashing.The flow of the maximum of liquid metals and therefore maximum poring rate can theoretically calculate (Borissow, G.P. " Dawlenie w uprawlenii litejnyzmiprozessami " (pressure in the casting process control), Kiew, Verl.Nauk.Dumka, 1988, S.121, Formel IV-18).This theoretical pressure can (when for example using liquid driving device) be monitored according to the adjusting of equipment and technology ground and according to the manometric demonstration of the liquid driving device of the displacement that is used for canister in the practice.Mould is filled fast to be needed, so that can obtain the homogeneous thickness of the metallic envelope that constitutes after on the inner surface of the wax-pattern casting mold of pottery.After filling melt, on the height that the pressure in its cavity reaches when maintaining and extruding to mould.As long as metallic envelope is formed on the inner surface of ceramic wax-pattern casting mold, the wax-pattern casting mold that will satisfy during the crystallization of the melt layer on the wall that abuts in the wax-pattern casting mold pottery prevents broken minimum requirement.The thickness of metallic envelope and the crystallization time of foundry goods is proportional and for the layer that reclines be 5% to 10% with respect to the crystallization time of the thinnest part of foundry goods.Then the remaining crystallization time internal pressure at the whole melt of wax-pattern casting mold rises to a value gradually, and this value is enough for the amount of contraction of giving the follow-up additional foundry goods of wax-pattern casting mold.The risk of breakage of the mould of pottery reduces when pressure rises gradually.At this pressure is enough, guarantees the amount of contraction when supplying with crystallization to foundry goods in the die casting clout of canister under this pressure.Amount of contraction is a known value for the casting alloy of most use.During crystallization, obtain enough pressure with respect to move (this moves with amount of contraction proportional) of wax-pattern casting mold, perhaps according to when casting quality is controlled, lacking to determine described enough pressure by what amount of contraction caused according to canister.Metallic envelope on the inner surface of wax-pattern casting mold allows to improve operating pressure generally, also guarantees the quality of the improvement of foundry goods at this.
The general characteristic of the scheme of being implemented (it relates to the equipment of content of the present invention) is new and sets out thus and have practicality, promptly settle the outer surface of the neck of container to be provided with a removable fire-resistant sleeve, it is positioned at canister like this, makes it not contact with the wall of the cup that is filled with melt of lining.Melt layer in this crystallization that constitutes on the cold wall of the cup of lining and fire-resistant sleeve in when cast does not stop their relative motion, when having a gap between them.This gap constitutes by the flange of the lining that is provided with on the top edge of the cup of removable lining, and its interior diameter is less than the interior diameter of the cup of lining.The overall diameter of fire-resistant sleeve self is suitable according to the overall diameter of the flange of matched in clearance and lining, forms the space of a sealing thus when melt being expressed in the wax-pattern casting mold.The size in this gap is tentatively from the acquisition until crystallization finishes of the casting process when keeping for a long time.Determining a gap in the radial direction, it surpasses the gross thickness of one-sided melt layer, this melt layer cast and keep when crystallization finishes crystallization on the wall of the cup of lining and crystallization on the wall of fire-resistant sleeve.The melt layer of crystallization has worth mentioning resistance for motion below the lower flat of the flange of lining, because it does not have carrier.Fire-resistant sleeve constitutes removable, and it is booked in the side by the remaining mould material that hardens because finish the back at casting process, takes off and is retained in the canister from the neck of settling container together with canister when the workbench in the bottom descends.Correspondingly the feature of equipment guarantee in different quick working methods and when guaranteeing inactive state canister in the expedite motion of settling internal tank, thereby on the inner surface of the wax-pattern casting mold of pottery, constitute the purpose that other metallic envelope realizes reinforcing the wax-pattern casting mold during melt layer crystallization on the inner surface of the wax-pattern casting mold by abutting in sleeve at one.
