In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the schematic device for being used to manufacture directional solidification castings in the utility model embodiment.
Embodiment
Present embodiment provides a kind of device for being used to manufacture directional solidification castings, it can avoid channel block
The problem of, and then ensure that casting quality.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1, Fig. 1 is the device signal for being used to manufacture directional solidification castings in the utility model embodiment
Figure.
The device provided in this embodiment for being used to manufacture directional solidification castings includes shell 1, and shell 1 is internally provided with cavity,
Cavity is used for the alloy material for accommodating molten condition, and alloy material is cooled into stable solid product in cavity.
The alloy material of molten condition is injected into cavity by pouring basin 2 and casting pressing port 3, and casting pressing port 3 is fixed and set
Put on the side wall of shell 1, the lower end closed of casting pressing port 3, upper end is preferably bell-mouth structure of air, so that pouring basin 2 is extend into
In casting pressing port 3.
Connected between casting pressing port 3 and cavity by multiple passages 4, multiple passages 4 are distributed in vertical direction, work as molten
After the alloy material of state is injected into casting pressing port 3 by pouring basin 2, liquid alloy in casting pressing port 3 by multiple passages 4 by
Gradually it is injected into cavity.
In the present embodiment, a turn coil installation cavity 5 is equipped with the periphery of each passage 4, in each coil installing ring 5
High-frequency induction heating coil 6 is installed, high-frequency induction heating coil is used to produce high-frequency alternating magnetic field, can heat passage rapidly
High temperature alloy in 4.Controller is used for the break-make for controlling high-frequency induction heating coil 6 and power supply.
So set, since the periphery of passage provided in this embodiment is equipped with high-frequency induction heating coil, controller control
High-frequency induction heating coil is turned on power supply, is realized heating, is avoided the problem that the alloy material cooled and solidified in passage, and then keep away
The problem of having exempted from channel block.
In addition, in order to avoid the alloy material of molten condition occur in the channel turbulent flow situation, the present embodiment it is preferred
In scheme, above-mentioned passage 4 is arranged to heeling condition, angle of inclination is 71 ° -75 °, it is necessary to explanation, above-mentioned angle of inclination
Refer to the angle between the extending direction of passage 4 and horizontal direction.
Further, above-mentioned passage 4 is set for the direction along casting pressing port 3 to cavity, cross section in the present embodiment
The gradual increased structure of product, in this way, the entrance of passage 4 is smaller, can play a role in filtering, but as alloy material is to passage
Flowing inside 4, the cross section of passage 4 gradually increase, and reduce the flow resistance of alloy material.
In the present embodiment, exhaust outlet 7 is equipped with the top of shell 1, as alloy material gradually fills cavity, in cavity
Gas can be discharged by the exhaust outlet 7 on top, avoid producing internal high pressure.
In addition in the present embodiment, along in top-down direction, the cross-sectional area of casting pressing port is gradually reduced.In this way, pouring basin 2
Its bottom can be rapidly filled with by flowing into the alloy material of casting pressing port 3, shorten casting time.
Further, filter screen 8 is equipped with the lower port of pouring basin, being arranged such further can avoid impurity from entering
In cavity, casting quality problems are caused.
