Referring to fig. 1-4, a superalloy casting apparatus comprises: an outer cavity 1; the inner molding base 2 is arranged in the outer cavity 1, and the molding cavity 3 is positioned between the outer cavity 1 and the inner molding base 2; the inner forming base 2 comprises a solid base 21, a trapezoid table 22 connected to the solid base 21 and a flow guide frame 23 fixed to the trapezoid table 22, molten metal flows into the forming cavity 3 along the flow guide frame 23 and the trapezoid table 22, the inner forming base further comprises a top cover 5, a matching hole is formed in the center of the inside of the top cover 5, the top of the inner forming base 2 further comprises a positioning head 24, and the positioning head 24 is matched with the matching hole.
Wherein, the high temperature alloy casting device is suitable for a tubular alloy structure, when the alloy casting is needed, the top cover 5 is firstly opened, the molten metal is poured onto the inner forming seat 2, the inner forming seat 2 is divided into two parts, at the moment, two pouring modes are provided, one mode is directly poured along the guide frame 23, the other mode is poured along the trapezoidal platform 22, when the alloy is poured along the guide frame 23, because the guide frame 23 is of an arc sheet structure, both sides of the guide frame are downward arcs, the raw material liquid flows downwards along the arcs and flows to the forming cavity 3 through the trapezoidal platform 22, when the method is adopted, the pouring speed of the raw material is not too high, otherwise the raw material is easy to sputter, the second mode is poured along the trapezoidal platform 22, when the raw material liquid contacts the trapezoidal platform 22, part of the raw material liquid flows downwards, part of the raw material liquid overflows, the overflowing part of the overflowing raw material liquid flows upwards to the arc edge of the guide frame 23 and continues downwards flowing, the whole feeding amount is not influenced, and even if the ejection phenomenon occurs when the raw material liquid is fed in by adopting the mode of feeding in the trapezoid table 22, the ejected raw material liquid can be blocked by the inner wall of the outer shape cavity 1 due to the lower height of the trapezoid table 22.
It should be emphasized that if the jig 23 is a flat surface, the trapezoidal table 22 needs to be aligned when the raw material is introduced, which is not favorable for rapid processing, and if the jig 23 is a flat surface, the raw material liquid is difficult to flow downward in the overflow phenomenon, which may result in a shortage of the raw material liquid, and once this phenomenon occurs, the weight or shape of the cast alloy structure may not meet the requirement, and the alloy structure may need to be re-manufactured in a furnace, which may waste a construction period.
Furthermore, before casting, the height of the alloy piece to be cast needs to be evaluated, and the height of the alloy piece needs to be lower than that of the solid seat 21, otherwise, the alloy piece cannot be in a normal cylindrical structure after casting, an irregular structure is formed along the trapezoidal table 22 in some parts, and the alloy shape is damaged by subsequent cutting.
After the raw material liquid is poured, the raw material liquid needs to be treated by air cooling or other cooling means to enable the raw material liquid to be rapidly molded, so in order to form a closed cooling environment in the molding cavity 3, a top cover 5 needs to be constructed at the top of the molding cavity 3, but the top cover 5 is difficult to fix due to the guide frame 23 which is of an arc sheet structure, so that the top cover 5 is fixed through the matching of the positioning head 24 and the matching hole, and a closed space is formed at the top of the molding cavity 3 in a sealing mode.
In the process of introducing raw material liquid, the compactness between the raw material liquid is not enough, so when the raw material is introduced and before condensation does not occur, the raw material liquid needs to be stirred, so the high-temperature alloy casting device further comprises a stirring mechanism 4 erected at the top of the outer cavity 1, wherein the stirring mechanism 4 comprises an outer mounting disc 41, a plurality of groups of driving structures 42 arranged on the outer mounting disc 41, a motor 43 driving the driving structures 42 to rotate, a driven structure 44 in transmission connection with the driving structures 42, and a stirring rod 45 vertically penetrating through the driven structure 44, wherein the stirring rod 45 is inserted into the forming cavity 3, and when stirring is needed, the driving structures 42 are driven to rotate through the rotation of the driving motor 43, so that the stirring rod 45 on the driven structure 44 is driven to stir.
After the stirring is completed, the stirring rod 45 needs to be scraped, and all the molten metal possibly attached to the surface of the stirring rod 45 needs to be scraped, so as to avoid the residual molten metal on the stirring rod 45 from affecting the volume of the molten metal, wherein the driving motor 43 is externally connected with a power supply or a battery, and the driving and wiring processes of the driving motor 43 are common knowledge in the art, and are not described in detail herein.
Wherein, the effect of outer mounting disc 41 is for the sake of facilitating the promotion with whole rabbling mechanism 4, when needing the ejection of compact, directly hangs up whole rabbling mechanism 4, can be convenient for the ejection of compact, simultaneously, also can strike off the excess stock with rabbling mechanism 4 when the puddler 45 need, and corresponding, 4 tops of rabbling mechanism can set up the manipulator of a hoist and mount, and for the sake of facilitating the hoist and mount, are provided with two otic placodes on the top of outer mounting disc 41, can be convenient for cooperate with the manipulator.
In this embodiment, drive structure 42 is the action wheel, driven structure 44 is from the driving wheel, drive structure 42 with through belt pulley transmission between the driven structure 44, and in other embodiments, drive structure 42 is the gear wheel, driven structure 44 is the pinion, adopts the mode of gear wheel drive pinion, can let the slew velocity of puddler 45 be connected with driven structure 44 faster, and stirring effect to the molten metal is better.
In the portion where the stirring mechanism 4 is added, it is obvious that the molten metal cannot be sputtered onto the inner wall of the outer cavity 1 after being poured onto the trapezoidal platform 22, but in order to achieve the protection effect as well, a through hole 46 matched with the top cover 5 is arranged on the outer mounting disk 41, the diameter of the through hole 46 is equal to the distance between the middle points of the two oblique sides of the trapezoidal platform 22, so that the molten metal cannot be sputtered onto the outer wall of the outer mounting disk 41 when being sputtered onto the trapezoidal platform 22, and the through hole 46 with a large opening does not influence rapid blanking, thereby improving the feeding speed while ensuring safe processing.
Further, an air cooling structure facing the molding cavity 3 is arranged in the outer cavity 1, wherein the air cooling structure can be an air blower, an air compressor, a vacuum machine and the like.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
