In chassis, replace the cross gate 264 and runner brick 22 of bottom, replace the sliding plate 24 frequently slided, by new sliding plate 24 with
After connector 29 re-assemblies next time, you can produced.
In embodiment one and embodiment two, one end and the sliding plate 24 of push rod 28 are removedly connected by bolt, branch
Frame 34 holds the other end that push rod 28 stretches out ontology 10, keeps the horizontality of push rod 28.
In embodiment one, the stretching motion of the output shaft of hydraulic cylinder or cylinder 38 directly drives driving member 32, driving member
32 move horizontally drives push rod 28 to move in the horizontal direction.
It in embodiment two, is connected through a screw thread between driving member 32 and mounting portion 344, the other end of driving member 32 can turn
It is connected to the other end of push rod 28 dynamicly.While rotating handle 36 drives driving member 32 to rotate, driving member 32 is in mounting portion 344
Inside spin is flexible, and driving member 32 can move along its axis (closer or far from ontology 10), in the horizontal direction to driving push rod 28
Movement.More preferably, the other end of driving member 32 can rotationally be sleeved on the other end of push rod 28 by bearing, due to push rod
28 one end is fixed with sliding plate 24, and driving member 32 is only capable of driving push rod 28 and moves horizontally.
In embodiment two, push rod 28 can also be enable rotationally to be connect with sliding plate 24, the driving transmission of rotating handle 36
While part 32 rotates, driving member 32 can move along its axis, and driving member 32 drives moving horizontally for push rod 28, drive sliding plate
24 between upper mounted plate 23 and bottom plate 25 horizontal sliding.
When work, steel ingot die and cast chassis are tightly connected, molten steel is by vertical running channel, cross gate 264, sluice way
262, lower through-hole 252, flowing hole 242, upper through-hole 232 and steel outlet hole 222 flow into the cavity of steel ingot die.It is poured according to different
Rate request is noted, driving driver (rotating handle 36, hydraulic cylinder or cylinder 38) makes push rod 28 drive sliding plate 24 horizontal sliding
It moves, adjusts and lead to steel area, change molten steel flow, meet technological requirement, it, can if needing repeatedly to carry out flow-rate adjustment in casting process
Repeatedly to be adjusted according to actual needs.
After casting complete, driver is driven, the movement for making push rod 28 that sliding plate 24 be driven to carry out larger stroke is realized to steel
The shear action of column, sliding plate 24 block steel outlet hole 222 completely；Stop driving at this time, the movement of push rod 28 accordingly stops, and slides
Plate 24 is fixed, and is ensured that sliding plate 24 persistently blocks steel outlet hole 222, has been blocked the flowing of molten steel, avoided the formation of continuous steel column,
The smooth demoulding of ingot mould may be implemented.So as to realize Above The Ingot Bottom and pour into a mould being kept completely separate for channel, traditional life is avoided
Steel ingot and cast channel can not be divided in production, need the problem manually cut, shorten demoulding time and efficiency, while right
Ingot quality has some improvement.
More preferably, ontology 10 includes upper body and lower body, opens up the accommodating chamber of M shape in lower body, in M shape
Heart position is connect with vertical running channel, and upper mounted plate 23, sliding plate 24, bottom plate 25 and drainage body 26 are placed in rice in accommodating chamber
Each terminal position of font (i.e. at steel outlet hole 222).The runner brick hole 12 of perforation, runner brick hole 12 and appearance are opened up in upper body
Chamber of receiving is connected to.
Particular embodiments described above has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the above is only a specific embodiment of the present invention, the protection being not intended to limit the present invention
Range.It particularly points out, to those skilled in the art, all within the spirits and principles of the present invention, that is done any repaiies
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
