Abstract
A strong cooling casting copper mold preparing ultra magnetostriction alloy disk is composed of an end cover, a bottom mold and cooling liquid. An annular groove is formed in an outer ring of the bottom mold and can contain the cooling liquid. The composition of the cooling liquid is Ga-In-Sn alloy, and cooling capacity is high. The end cover can be separated from the bottom mold and be replaced. Cooling for two casting modes can be achieved through replacement of the end cover, and the two casting modes are crucible casting and quartz tube casting. An inner ring of the bottom mold is a casting cavity, the bottom of the inner ring is provided with vent holes, and the height of the cavity is 5-10mm. The strong cooling casting copper mold can improve cooling speed of alloy ingot crystal substantially, and the purposes of refining grains, reducing alloy structure loose and improving structure performance of alloy ingot are achieved. Meanwhile, due to the fact that the cooling speed is high, alloy prepared through the method keeps more unordered phase structures of liquid metal, and comprehensive performance of the alloy is improved obviously. The strong cooling casting copper mold is simple in structure and greatly reduces manufacturing cost.
Description
Technical field
Required casting mould when the utility model relates to a kind of vacuum induction melting method and prepares the ultra-magnetic telescopic alloy belongs to the technology of die manufacturing of materials processing engineering field.
Background technology
The melting of metal material generally all is with electric arc melting or induction melting.Electric arc melting need not cast, and need not mould yet, and the material volume of producing is very little, is commonly called as the button ingot.And induction melting must be cast in the mould.Traditional mould all is simple red copper mould or water-cooled metal copper mould.Tradition red copper mould structure is simple, and cooling capacity is limited, so the alloy bar material coarse microstructure that casts out, poor-performing.Though water-cooled metal copper mould cooling capacity is strong, seep water easily, leak, cause moisture increase in the vacuum drying oven, destroy vacuum environment.The water-cooled mould causes the vacuum drying oven complex structure simultaneously, makes difficulty, increases equipment cost greatly.
Through consulting document; Feng of Bohai Piston Co., Ltd., Bingzhou City, Shandong Prov. increase build, Wei Zuoshan announced a kind of aluminium piston water-cooled die device with heat-insulation layer; (China; utility model patent; notification number 201832985U) is provided with a water-cooled vestibule in this technology in the mould; water-cooled vestibule inwall is equipped with a heat-insulation layer, forms a complete circulation waterway.Thereby improve the density of mold cools down ability and tissue.Structure is comparatively complicated, has improved cost undoubtedly but as a whole.And circulation waterway is very high to the sealing requirements of structure.
Further searching document is found, Shenyang Xinguang Huaxu Casting Co., Ltd. has announced a kind of cylinder cover metal casting mould with exhaust structure in refined, Zhu Min, entire die is made up of patrix, left and right sides side form and bed die in (China, utility model patent, notification number 201295744Y) this technology.Left and right sides mould also is made up of upper and lower mould respectively, and has the groove of some exhausts on the surface of butt joint.Therefore the gas in the die cavity is got rid of smoothly, effectively eliminated producing the probability of owing to cast.But the cooling effect of this mould is not good, and the compactness that forms foundry goods is not enough.The combination property of material is difficult to improve.
The preparation metal material technology that analysis-by-synthesis has been announced can be learnt, the shortcoming that existing technology is difficult to overcome below existing:
When adopting traditional cast metal mould, cooling velocity is little, and crystal grain is thick, is difficult to improve the combination property of material;
If adopt the water-cooled mould, mould easily leaks, and causes the destruction of the vacuum environment of vacuum equipment;
The water-cooled mould causes the vacuum drying oven complex structure, makes difficulty, increases equipment cost greatly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of strong cold copper mould of metal casting of built-in metal cooling fluid is provided, can increase considerably the crystallization cooling velocity of alloy cast ingot effectively, thereby reach crystal grain thinning, it is loose to reduce alloy structure, improves the purpose of alloy cast ingot structure property.
The structure that copper mould is made in a kind of strong chill casting for preparing ultra-magnetic telescopic alloy disk described in the utility model comprises end cap, bed die; The bed die outer ring is provided with annular groove, and the built-in cooling fluid of groove, cooling fluid are the Ga-In-Sn alloy; The bed die inner ring is the casting die cavity, and the die cavity height is 5 ~ 10mm; The bottom centre of bed die has the connection steam vent; End cap is stuck on the bed die, and end cap is replaceable, to realize the cooling of two kinds of casting modes, i.e. the casting of crucible casting and quartz ampoule.
The beneficial effects of the utility model are: compared with the prior art, the prepared alloy grain of the utility model is tiny, composition evenly and casting character significantly improve.Can select for use two kinds of different end caps to realize the casting of different modes.Has stronger specific aim.Not only can crystal grain thinning, and the size that can make crystal grain is evenly, significantly improves the combination property of alloy.

Fig. 2 is the structure vertical view when adopting the quartz ampoule casting in the utility model;
Fig. 3 is the structural front view when adopting the crucible casting in the utility model;
Fig. 4 is the structure vertical view when adopting the crucible casting in the utility model;
Wherein: 1. end cap 2. cooling fluids 3. bed dies that gate diameter is big and thick.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated:
Among Fig. 1-4, the strong cold copper mould of a kind of metal casting of built-in metal cooling fluid is made up of end cap 1, cooling fluid 2 and bed die 3.Bed die 3 outer rings are provided with annular groove, can put cooling fluid 2 in the groove.Cooling fluid 2 in the groove is the Ga-In-Sn alloy, is in a liquid state under the normal temperature, has stronger cooling capacity.End cap 1 is separable with bed die 3, and end cap 1 is replaceable.Change end cap 1 and just can realize the cooling of two kinds of casting modes, the casting of crucible casting and quartz ampoule.The material of end cap 1 is stainless steel, and the material of bed die 3 is red copper.Bed die 3 inner rings are the casting die cavity, and the bottom has steam vent.The die cavity height is about 8mm.
