Motlten metal keeps stove 101 such as to keep the motlten metal M1 of such as aluminum or aluminum alloy and so on, and it is remained on predetermined temperature.In example in FIG, motlten metal M1 is not added motlten metal and keeps in stove 101, and therefore the surface (that is, motlten metal liquid level) of motlten metal M1 is carried out along with casting and declines.But motlten metal also immediately can be added to motlten metal and keep in stove 101 in casting process, keep constant to make motlten metal liquid level.Certainly, motlten metal M1 can be other metal or alloy in addition to aluminum.
Interior shape determining means 102a and outer shape determining means 102b is made up of such as pottery or stainless steel, and is configured near molten metal surface.In the example depicted in fig. 1, interior shape determining means 102a and outer shape determining means 102b are arranged to contact with molten metal surface.But interior shape determining means 102a and outer shape determining means 102b also can be arranged to make their interarea being positioned at downside (that is, motlten metal side) not contact with molten metal surface.More specifically, predetermined gap (such as about 0.5mm) can be provided with between molten metal surface and the downside interarea of interior shape determining means 102a and outer shape determining means 102b.
In addition, interior shape determining means 102a determines the interior shape of foundry goods M3, and outer shape determining means 102b determines the outer shape of foundry goods M3.Foundry goods M3 shown in Fig. 1 is the hollow casting (that is, pipeline) in the lateral direction with tubular section (being called hereinafter " cross section ").That is more specifically, interior shape determining means 102a determines the internal diameter of the cross section of foundry goods M3, and outer shape determining means 102b determines the external diameter of the cross section of foundry goods M3.
Fig. 2 is the top view of interior shape determining means 102a and outer shape determining means 102b.Here, the interior shape determining means 102a in Fig. 1 and the sectional view of outer shape determining means 102b correspond to the sectional view intercepted along the line I-I in Fig. 2.As shown in Figure 2, outer shape determining means 102b has the flat shape of such as rectangle, and in central portion, have circular opening portion.Interior shape determining means 102a has such as circular flat shape, and is configured in the central portion of the opening portion of outer shape determining means 102b.Gap between interior shape determining means 102a and outer shape determining means 102b is the motlten metal passage 102c passed through for motlten metal.Like this, attaching parts 102 are made up of interior shape determining means 102a, outer shape determining means 102b and motlten metal passage 102c.
As shown in Figure 1, motlten metal M1 by the surface tension of motlten metal and skin covering of the surface follow foundry goods M3 by draw, and by motlten metal passage 102c.Here, follow foundry goods M3 by the skin covering of the surface of motlten metal and surface tension will be referred to as " the motlten metal M2 be kept " from molten metal surface by the motlten metal drawn.In addition, the interface between foundry goods M3 and the motlten metal M2 be kept is freezing interface.
Cramp bar 103 supports interior shape determining means 102a, and cramp bar 104 supports outer shape determining means 102b.Position relationship between interior shape determining means 102a and outer shape determining means 102b can be maintained by these cramp bars 103 and 104.Here, make cramp bar 103 be pipeline configuration, make refrigerating gas flow through cramp bar 103 and in interior shape determining means 102a, also arrange blowout hole to make also to cool foundry goods M3 from inner side.

Refrigerating gas nozzle (cooling end) 106 is for spraying refrigerating gas (such as, air, nitrogen, argon gas etc.) to cool foundry goods M3 to foundry goods M3.Foundry goods M3 by draw on that be connected with starter ST, unshowned machine draws while the gas that is cooled cool.Therefore, the motlten metal M2 be kept be positioned near freezing interface solidifies in turn, thus forms foundry goods M3.Here, also thus improving casting speed to improve from the heat radiation of foundry goods M3, preferably making the temperature of refrigerating gas low as far as possible.Such as, can the extremely low gas of serviceability temperature, the refrigerating gas gasified of the refrigerating gas such as cooled by liquid gas or liquid gas (such as, liquid nitrogen or liquid argon).
Motlten metal cooler (motlten metal cooling end) 107 is designed to reduce the temperature of the motlten metal M1 be positioned at immediately below interior shape determining means 102a and outer shape determining means 120b.Only make cooling agent cycle through motlten metal cooler 107 when the temperature of motlten metal M1 will be reduced.The setting of motlten metal cooler 107 is features for the free casting device according to this exemplary embodiment.
Cooling agent imports in motlten metal cooler 107 by coolant conduit 108, makes cooling agent cycle through motlten metal cooler 107, and is derived from motlten metal cooler 107 by the cooling agent dispelled the heat from motlten metal M1.In addition, coolant conduit 108 supports motlten metal cooler 107.Cooling agent is not particularly limited, but from a security point of view, refrigerating gas (such as, air, nitrogen, argon gas etc.) is preferred.In addition, as the method for making cooling agent circulate, from a security point of view, drawing-in type method than adding pressure type method more preferably.
The material of motlten metal cooler 107 and coolant conduit 108 is not particularly limited.Such as, this material can be pottery or stainless steel.In addition, when using stainless steel, preferably implementing the countermeasure preventing motlten metal from losing, such as, being wound around heatproof zone at the portion contacted with motlten metal M1.
Fig. 3 is the top view of the detailed configuration example of motlten metal cooler 107.In figure 3, interior shape determining means 102a and cramp bar 103 are both shown in broken lines so that understand plan positional relationship.Motlten metal cooler 107 shown in Fig. 3 is made up of single spiral type pipe.That is motlten metal cooler 107 and coolant conduit 108 are integrally formed.As shown in Figure 3, in the central portion of motlten metal cooler 107, circular opening portion is formed with.Cramp bar 103 is through this opening portion.This structure inhibits the interference between cramp bar 103 and motlten metal cooler 107.
Fig. 4 is the top view of another detailed configuration example of motlten metal cooler 107.In the diagram, equally, interior shape determining means 102a and cramp bar 103 are both shown in broken lines so that understand plan positional relationship.Motlten metal cooler 107 shown in Fig. 4 is made up of single bend pipe (whole pipe is snakelike), and wherein linear portion 107a and U-shaped portion 107b alternately repeats.That is motlten metal cooler 107 and coolant conduit 108 are integrally formed.As shown in Figure 4, at the central portion of motlten metal cooler 107, the interval between two adjacent linear portion 107a is comparatively large, and cramp bar 103 is through herein.This structure inhibits the interference between cramp bar 103 and motlten metal cooler 107.The structure of the motlten metal cooler 107 shown in Fig. 3 and 4 is only an example.Other configuration example various is also possible.
Coolant conduit 108 is connected with actuator 109.As shown in Figure 1, actuator 109 makes motlten metal cooler 107 can move along the vertical direction in motlten metal M1.Motlten metal cooler 107 also can be moved in left-right direction and comply with interior shape determining means 102a and outer shape determining means 102b.
When the temperature of the motlten metal M1 be positioned at immediately below interior shape determining means 102a and outer shape determining means 102b will be reduced, cooling agent can be made at motlten metal cooler 107 Inner eycle, and motlten metal cooler 107 can be made to rise it is moved into closer to interior shape determining means 102a and outer shape determining means 102b.On the other hand, in what its situation in office, the cooling agent circulation in motlten metal cooler 107 all can be made to stop, and motlten metal cooler 107 can be made to decline to make it move apart interior shape determining means 102a and outer shape determining means 102b.
Next, the effect of motlten metal cooler 107 will be described in detail.The temperature of motlten metal M1 keeps stove 101 to maintain predetermined proper temperature all the time by motlten metal.Here, proper temperature is the temperature for freezing interface being remained on suitably height.The height of freezing interface is maintained by the balance between the heat radiation and lead speed of foundry goods M3.Such as, when when the thickness of casting process medium casting M3 is large, the thermal capacity of the motlten metal M2 be kept increases, and therefore described balance has not existed, and the position of freezing interface rises, and is difficult to obtain the shape expected.That is formability worsens.
Now, in order to make the position of freezing interface get back to original suitable height, if can not improve the heat radiation from foundry goods M3, then the casting speed that must slow down maybe must reduce the temperature of motlten metal M1.In order to reduce the temperature of motlten metal M1, only need the design temperature reducing motlten metal maintenance stove 101.But whole motlten metal M1 drops to design temperature practically will expend a lot of time.For existing free casting device, must slow down casting speed before the temperature of whole motlten metal M1 drops to design temperature.
Comparatively speaking, the free casting device according to this exemplary embodiment is provided with motlten metal cooler 107, therefore can reduce the temperature of motlten metal M1 at short notice.Especially, motlten metal cooler 107 is positioned at immediately below interior shape determining means 102a and outer shape determining means 102b, therefore the temperature being only positioned at the motlten metal M1 of (or more specifically, being positioned at immediately below interior shape determining means 102a and outer shape determining means 102b) near interior shape determining means 102a and outer shape determining means 102b can reduce at short notice.Therefore, without the need to the casting speed that slows down, thus casting speed can than fast when existing free casting device.As a result, the casting time is shorter, therefore improves productivity ratio.
