Abstract
The utility model discloses a vacuum smelting die-casting unit which comprises a vacuum pump set, a vacuum tank connected with the vacuum pump set, a smelting system connected with the vacuum tank, and a control system. The vacuum smelting die-casting unit also comprises a die-casting system connected with the vacuum tank, and the smelting system is connected with the die-casting system. The structure is adopted by the utility model, one vacuum pump set can simultaneously provide vacuum for the smelting system and the die-casting system, i.e. the utility model can simultaneously realize the vacuum smelting and the vacuum die-casting, has compact structure without larger vacuum housing, needs little vacuum pumping volume, and is especially suitable for the vacuum smelting and the vacuum die-casting of non-crystalline materials.
Description
Technical field
The utility model belongs to the metal casting technical field, more particularly, relates to a kind of vacuum melting die casting equipment.
Background technology
Vacuum melting technology is under oxygen-free atmosphere solid material to be melted, smelting equipment of the prior art comprises vacuum (-tight) housing and places vacuum (-tight) housing interior working chamber and mould, its course of work is: earlier the air in the vacuum (-tight) housing is extracted, the pending material in the working chamber is heated until fusing, the liquation after will melting is then poured in-mold molding into again.The defective of this mode is that the volume of vacuum (-tight) housing is bigger, and the volume that need vacuumize is bigger, and the efficient of system is low, and comparatively difficult with combining of die casting equipment.
The evacuated die-casting process technology is the gas in the die cavity to be found time or partly find time, reduce the air pressure in the die cavity, be beneficial to fill the eliminating of gas in type and the alloy melt, make the effect retrofilling die cavity of alloy melt, and under pressure, solidify and obtain fine and close die casting at pressure.Vacuum die-casting method is compared with common casting die has following characteristics: 1, the porosity reduces greatly; 2, the hardness height of the foundry goods of evacuated die-casting process, microstructure is tiny; 3, the mechanical property of evacuated die-casting process part is higher.In the prior art, evacuated die-casting process is to extract the gas in the die cavity, and its specific practice mainly contains two kinds, and first kind of mode is to put mould to bleed in vacuum (-tight) housing; The second way is directly to bleed from mould.Above-mentioned dual mode all needs to be provided with in addition the vacuum melting equipment with vacuum (-tight) housing, same existence need vacuumize bulky problem, and when liquation is transferred to evacuated die-casting process equipment kind from vacuum melting equipment, sneak into impurity easily, relatively poor for the applicability of non-crystalline material.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can realize vacuum melting and evacuated die-casting process simultaneously, and vacuumizes the less vacuum melting die casting equipment of volume.
The technical solution of the utility model is: a kind of vacuum melting die casting equipment is provided, comprise vavuum pump group, the vacuum tank that is connected with described vavuum pump group, with tank connected smelting system of described vacuum and control system, described vacuum melting die casting equipment comprises also and the tank connected die-casting system of described vacuum that described smelting system is connected with described die-casting system.
Compared with prior art, technique scheme is that smelting system and die-casting system provide vacuum with a cover vavuum pump group simultaneously, can realize vacuum melting and evacuated die-casting process simultaneously, its compact conformation, need not the vacuum (-tight) housing that uses volume bigger, it is little to vacuumize volume, is particularly suitable for the vacuum melting and the evacuated die-casting process of non-crystalline material.
Description of drawings
Fig. 1 is the structural principle schematic diagram of the utility model one preferred embodiment.
The specific embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1, preferred embodiment for the utility model vacuum melting die casting equipment, it comprises vavuum pump group 1, the vacuum tank 2 that is connected with vavuum pump group 1, the smelting system 3 that is connected with vacuum tank 2 and die-casting system 4 and control system (not shown), links together by pipeline between smelting system 3 and the die-casting system 4.Like this, present embodiment is that smelting system 3 provides vacuum with die-casting system 4 with a cover vavuum pump group 1 simultaneously, can realize vacuum melting and evacuated die-casting process simultaneously, its compact conformation, need not the vacuum (-tight) housing that uses volume bigger, it is less to vacuumize volume, and melt for closed state, is particularly suitable for the higher non-crystalline material of purity requirement is carried out vacuum melting and evacuated die-casting process 4 the transmittance process from smelting system 3 to die-casting system.
Vavuum pump group 1 comprises one-level mechanical pump 11 and secondary lobe pump 12, and wherein, the air inlet of secondary lobe pump 12 is connected with vacuum tank 2, and the air inlet of one-level mechanical pump 11 is connected with the gas outlet of secondary lobe pump 12.Certainly, as required, can also adopt the vavuum pump of other types to be cascaded to form the vavuum pump group.
Between vacuum tank 2 and smelting system 3, can establish push-pull valve or control valve 5.Equally, between vacuum tank 2 and die-casting system 4, also can establish push-pull valve or control valve 5.The pipeline between vacuum tank 2 and smelting system 3 and the die-casting system 4 can be blocked and open to push-pull valve, and control valve can be for the vacuum of regulating in smelting system 3 and the die-casting system 4.
During work, start mechanical pump 11 by control system earlier, lobe pump 12 starts when the pressure in the vacuum tank 2 reaches 1500 handkerchiefs, make pressure drop to 2 handkerchief in the vacuum tank 2, at this moment die casting machine matched moulds, in the working chamber, throw in amorphous master alloy or other materials to be processed, open push-pull valve or control valve 5, be about to smelting system 3 and die-casting system 4 access vacuum systems, when pressure to 4 handkerchief in working chamber and the die casting machine, vacuum melting begins, and is imported into die-casting system 4 after the formed alloy liquation of vacuum melting reaches requirement, and this moment, die casting machine was started working, after die casting is finished, push-pull valve or control valve 5 are closed, and working chamber and mould and vacuum system disconnect, and product is taken out in the die casting machine die sinking.Continue melting as need, throw in foundry alloy once more, and repeat above-mentioned steps to the working chamber.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
