Abstract
The present invention relates to a kind of hollow steel-ingot casting mould tool, mainly including pedestal, external mold, mold core and teeming speed adjusting mechanism；The mold core is sealed in external mold along common central axis direction on pedestal and mold core is placed in inside external mold；The teeming speed adjusting mechanism includes body and cover board；The body includes being evenly arranged with circular ring shape tablet, the connecting tube one being arranged above tablet inner edge and the connecting tube two being arranged at below flat board outer rim of multiple through holes one；The body is connected with mold core by connecting tube one, is connected by connecting tube two with external mold；The cover board is also circular ring shape, and one correspondence position of through hole is being provided with through hole two, and the cover board is rotatable to be sheathed in connecting tube one.The present invention can be played the role of adjusting teeming speed by the size for adjusting gas outlet between external mold and mold core while firm fixed mold core, simple in structure, highly practical.
Description
Technical field
Present invention setting and fine work steel preparing technical field more particularly to a kind of hollow steel-ingot casting mould tool.
Background technology
The manufacture of hollow steel ingot has the advantages that following：Forging times are reduced, the forging recovery rate of steel ingot is improved, reduces
Steel ingot weight makes full use of equipment potential.But the manufacture of hollow steel ingot has very big difficulty, the key technology of manufacture is：
The easy extraction of fuse and inner surface flawless among the manufacture requirement of steel ingot endoporus；The curdled appearance of steel ingot is good, that is to say, that in
Heart hole must can be sufficiently carried out cooling down, to ensure final line of solidification close to the centre of wall thickness.Centre bore cooling is most
Using the method for circulating cooling gas, this method intensity of cooling poor controllability, adaptability when for the casting of different steel grades
It is not strong.
The content of the invention
It is required to adjust teeming speed by shirtsleeve operation to reach centre bore cooling, the present invention provides following technical side
Case：
A kind of hollow steel-ingot casting mould tool, including pedestal, external mold, mold core；The mold core and external mold are along common central shaft
Direction is sealed on pedestal and mold core is placed in inside external mold；The mold core is higher than external mold；It is characterized in that：Further include a teeming speed
Adjusting mechanism；The teeming speed adjusting mechanism includes body and cover board；The body includes the circle that rule setting has multiple through holes one
Ring plate, the connecting tube one being arranged above tablet inner edge and the connecting tube two being arranged at below flat board outer rim；Described
Body is connected with mold core by connecting tube one, is connected by connecting tube two with external mold；The cover board also for circular ring shape, and with through hole
One correspondence position is provided with through hole two, and the cover board is rotatable to be sheathed in connecting tube one.
By rotate the cover can change the size of the gas outlet between interior external mold with this come limit into mold molten steel speed
Degree can then reach centre bore cooling requirement on the premise of cooling gas ingredient and flow velocity is not changed.
Further, the connecting tube two includes inner and outer tubes, and the external mold is recessed embedded in being formed by inner and outer tubes
In slot；Said inner tube, external mold, outer tube are provided with threaded hole in correspondence position, and said inner tube, external mold, outer tube are screwed by screw
Threaded hole is fixed, and can further be fixed mold core, be prevented mold core from occurring displacement in casting cycle.
Further, the connecting tube one is connected by screw with mold core.
Further, the cover board outer rim is also connected with a handle, facilitates the rotation of cover board.
The beneficial effects of the present invention are：It can be while firm fixed mold core, by adjusting between external mold and mold core
The size of gas outlet plays the role of adjusting teeming speed, simple in structure, highly practical；Meanwhile external mold can demould simultaneously with mold core.
Description of the drawings
The sectional view of Fig. 1, the present invention.
The primary structure schematic diagram of Fig. 2, teeming speed adjusting mechanism.
In figure：1st, pedestal, 2, external mold, 3, mold core, 411, tablet, 412, connecting tube one, 431, inner tube, 432, outer tube,
414th, through hole one, 42, cover board, 421, through hole two, 43, handle, 44, screw.
Specific embodiment
A kind of hollow steel-ingot casting mould tool, including pedestal 1, external mold 2, mold core 3；The mold core 3 and external mold 2 are along in common
Mandrel direction is sealed on pedestal 1 and mold core 3 is placed in inside external mold 2；The mold core 3 is higher than external mold 2；It is characterized in that：Also wrap
Include a teeming speed adjusting mechanism；The teeming speed adjusting mechanism includes body and cover board 42；The body has more including rule setting
The circular ring shape tablet 411 of a through hole 1, the connecting tube 1 being arranged above 411 inner edge of tablet and it is arranged at tablet
Connecting tube two below 411 outer rims；The body is connected by connecting tube 1 with mold core 3, by connecting tube two and external mold 2
Connection；The cover board 42 is also circular ring shape, and one 414 correspondence position of through hole is being provided with through hole 2 421, and the cover board 42 can
Rotation is sheathed in connecting tube 1.
The connecting tube two includes inner tube 431 and outer tube 432, and the external mold 2 is embedded in and is formed by inner tube 431 and outer tube 432
Groove in；Said inner tube 431, external mold 2, outer tube 432 are provided with threaded hole in correspondence position, said inner tube 431, external mold 2, outer
Pipe 432 is threaded into hole by screw 44 and fixes, and can further fix mold core 3, prevent mold core 3 from occurring in casting cycle
Displacement.
The connecting tube 1 is connected with mold core 3 by screw 44.
42 outer rim of cover board is also connected with a handle 43, facilitates the rotation of cover board 42.
Gas outlet size between interior external mold 2 can be changed by rotating the cover 42, the molten steel into mold is limited with this
Speed can then reach centre bore cooling requirement on the premise of cooling gas ingredient and flow velocity is not changed.
Using above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Can various changes and amendments be carried out without departing from the scope of the technological thought of the present invention'.This invention it is technical
Scope is not limited to the content on specification, it is necessary to determine its technical scope according to right.
