Description
Technical Field
The utility model belongs to the technical field of casting equipment, and particularly relates to a liquid lifting pipe for anti-gravity casting pouring.
Background
Antigravity casting is a casting and pouring process developed in the 50 s of the 20 th century. The method is a method for filling casting mould along the liquid lifting pipe from bottom to top against gravity and other resistance under the action of pressure by molten metal in the crucible, and obtaining casting under pressure. According to the pressure applied by the molten metal filling mold, the antigravity casting can be classified into low pressure casting, differential pressure casting, pressure regulating casting, vacuum suction casting, and the like.
At present, in the antigravity casting process, a common liquid lifting pipe is mainly used, the common liquid lifting pipe is of an up-down straight type, in the production casting process, molten metal is filled upwards through an opening at the bottom of the liquid lifting pipe, after one-time low-pressure casting is completed, residual molten metal in the liquid lifting pipe flows back into a crucible, oxides and gas are easily generated, and the quality of the molten metal is reduced.
Thus, improvements are needed.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a liquid lifting tube for anti-gravity casting pouring, which comprises a liquid lifting tube body, wherein the liquid lifting tube body is cylindrical, the bottom end of the liquid lifting tube body is provided with a conical bottom with a big top and a small bottom, four bosses are uniformly distributed on the side wall of an inner cavity of the liquid lifting tube body along the circumferential direction, the top end of the liquid lifting tube body and the bottom end of the conical bottom are respectively provided with an upper port and a lower port, a plug is arranged in the inner cavity of the conical bottom, and the appearance of the plug is matched with the inner cavity of the conical bottom.
Alternatively, the four bosses are located 10-12mm above the conical bottom.
Specifically, four bosses can play a certain role in blocking and limiting the plug, and the plug is prevented from being impacted by metal liquid flow to change positions randomly.
Alternatively, the angle between the outer conical surface of the conical bottom and the vertical is 14-15 °.
The utility model also comprises other components which can enable the riser tube for the antigravity casting pouring to be normally used, and the other components are all conventional technical means in the field. In addition, the devices or components not defined in the present utility model are all conventional in the art.
The working principle of the utility model is that when in operation, the molten metal in the crucible flows in from the lower port of the liquid lifting pipe under the action of pressure, the plug in the conical bottom of the liquid lifting pipe is punched, the plug is jacked up upwards, and the molten metal fills the casting mould from bottom to top against gravity and other resistance along the gap between the plug and the liquid lifting pipe body; after one round of pouring is completed, the plug falls back under the action of gravity and is matched with the conical bottom of the liquid lift pipe, so that the molten metal in the liquid lift pipe is prevented from flowing back, and the molten metal is left in the liquid lift pipe; the operation is repeated in the next round of casting.
The utility model has the advantages that the traditional lift tube structure is improved, the oxide generated by the backflow of the metal liquid can be effectively avoided, the quality of the metal liquid is improved, the scouring of the metal liquid to the lift tube is reduced, and the service life of the lift tube is prolonged.

Detailed Description
The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown, and in which embodiments of the utility model are shown. All other embodiments, modifications, equivalents, improvements, etc., which are apparent to those skilled in the art without the benefit of this disclosure, are intended to be included within the scope of this utility model.
Examples
As shown in fig. 1-3, the embodiment of the utility model provides a lift tube for antigravity casting pouring, which comprises a lift tube body 1, wherein the lift tube body 1 is cylindrical, the bottom end of the lift tube body 1 is provided with a conical bottom 2 with a large upper part and a small lower part, four bosses 3 are uniformly distributed on the side wall of an inner cavity of the lift tube body 1 along the circumferential direction, the top end of the lift tube body 1 and the bottom end of the conical bottom 2 are respectively provided with an upper port and a lower port, a plug 4 is arranged in the inner cavity of the conical bottom 2, and the appearance of the plug 4 is matched with the inner cavity of the conical bottom 2.
Four bosses 3 are all located 10mm above the conical bottom 2.
It is understood that the four bosses 3 can play a certain role in blocking and limiting the plug 4, so as to avoid the plug 4 from being impacted by the metal liquid flow to change positions randomly.
The angle between the outer conical surface of the conical bottom 2 and the vertical direction is 14 degrees.
The working principle of the utility model is that when in operation, the molten metal in the crucible flows in from the lower port of the liquid lifting pipe under the action of pressure, the plug 4 in the conical bottom 2 of the liquid lifting pipe is punched, the plug 4 is jacked up, and the molten metal fills the casting mould along the gap between the plug 4 and the liquid lifting pipe body 1 from bottom to top against gravity and other resistance; after one round of pouring is completed, the plug 4 falls back under the action of gravity and is matched with the conical bottom 2 of the lift tube, so that the molten metal in the lift tube is prevented from flowing back, and the molten metal is left in the lift tube; the operation is repeated in the next round of casting.
The embodiments of the present utility model have been described above, the description is illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
