Abstract
The utility model discloses a casting sprue structure and provides an improved funneling sprue cup which is simple in structure, smooth in molten iron pouring and high in pouring speed and improves casting quality. The improved funneling sprue cup solves the technical problems that turbulent flowing and splashing of molten iron can occur easily in the process of pouring, the pouring speed is low, slag blowholes and blowholes can be easily formed in castings, and therefore the casting quality is reduced and the like in the prior art. The improved funneling sprue cup comprises a cup body. An outflow hole is arranged in the bottom of the cup body, a containing cavity of the cup body is of a square column shape, and a side wall in the containing cavity of the square column shape extends outwards to form a conical-surface-shaped sprue.
Description
Technical field
The utility model relates to a kind of casting pouring gate structure, relates in particular to a kind of molten iron and injects steadily, and poring rate is fast, and improves the funneling cup of modified of casting quality.
Background technology
Existing casting cast gate is generally right circular cone or beveled cone shape, molten iron is prone to turbulent flow and splashes during cast, not only poring rate is slow, and residue and air can enter in the casting mold and form cinder hole and the pore of foundry goods along with molten iron in the casting process, thereby has reduced the quality of foundry goods.
Chinese patent discloses a kind of Flabelliform-slope buffered sprue cup for casting (CN101791694A), comprise the cup cup, the cup cup is provided with fan-shaped liquid-bath, the bottom surface of liquid-bath is domatic, and the highest point of bottom surface is positioned at the larger diameter end of liquid-bath, lowest part is positioned at the smaller diameter end of liquid-bath, and the minor diameter place of liquid-bath is provided with the down gate that connects vertically downward.Cast gate in this structure is the beveled cone shape, therefore same when having cast molten iron be prone to turbulent flow and splash, not only poring rate is slow, and residue and air can enter in the casting mold and form cinder hole and the pore of foundry goods along with molten iron in the casting process, thereby the technical problems such as quality of foundry goods have been reduced.
Summary of the invention
The utility model has mainly provided a kind of simple in structure, molten iron injects steadily, poring rate is fast, and the funneling cup of modified of raising casting quality, molten iron is prone to turbulent flow and splashes when having solved the cast that exists in the prior art, not only poring rate is slow, and foundry goods easily forms cinder hole and pore, thereby reduces the technical problem of casting quality etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the funneling cup of a kind of modified, the cup that comprises cup, bottom at cup is provided with flow-out hole, the container cavity of described cup is square column type, and the rear formation cone-shaped inlet that stretches out of a sidewall in the container cavity of square column type.The first half of the rim of a cup of cup is designed to semicircle, latter half is designed to square, and centered by flow-out hole, the container cavity of cup is asymmetric funnel-form, during cast, on the slope of molten iron first half in funnel at the bottom of orderly flow to glass, carrying over flow-out hole enters in the casting mold again, because stopping of the straight wall of latter half arranged, molten iron is taken advantage of a situation steadily enter in the flow-out hole, not only poring rate is fast, and molten iron turbulent flow can not occur and splash in cup, residue and air namely can not occur can enter in the casting mold and form the phenomenon of cinder hole and the pore of foundry goods along with molten iron, has improved the quality of foundry goods.
As preferably, the container cavity sidewall of described cone-shaped inlet both sides is the inclined-plane, itself and cone-shaped inlet smooth transition, and the container cavity sidewall bottom of the bottom of cone-shaped inlet and cone-shaped inlet both sides extends to respectively flow-out hole.The container cavity sidewall of cone-shaped inlet both sides is inclined-plane and during with cone-shaped inlet smooth transition, guarantees that molten iron flow is steady, and takes advantage of a situation and directly enter flow-out hole, avoids molten iron and container cavity sidewall and a cup end to bump and causes turbulent flow and splash.
As preferably, described flow-out hole central shaft and the distance of cone-shaped inlet central shaft are 1.5 times to 2.5 times of distance of the flow-out hole central shaft container cavity sidewall relative with the cone-shaped inlet.Cup is outward extending when semicircle corresponding to the first half of cone-shaped inlet, and the grade reduction that molten iron is flowed downward guarantees that molten iron steadily enters flow-out hole.
As preferably, the container cavity sidewall relative with described cone-shaped inlet is outward-dipping inclined-plane, upper end, and the inclination angle on inclined-plane is 3 ° to 5 °.The inclined-plane is easy to the cup processing and forming.
As preferably, the central shaft of described flow-out hole is positioned on the median plane of cone-shaped inlet.When flow-out hole and cone-shaped inlet median plane are coplanar, guarantee that molten iron directly enters flow-out hole, avoid molten iron and sidewall to bump and cause the turbulent flow and splash.
Therefore, the funneling cup of modified of the present utility model has following advantage: the first half of the rim of a cup of cup is large semi-circular, latter half is square, make the container cavity of cup be asymmetric funnel-form, flow-out hole is positioned at the middle part, the cup end near straight wall side, at the bottom of molten iron flows to glass in order along the slope of first half in the funnel during cast, carrying over flow-out hole enters in the casting mold again, owing to there is the straight wall of latter half to stop, molten iron is taken advantage of a situation steadily to be entered in the flow-out hole, not only poring rate is fast, and molten iron turbulent flow can not occur and splash in cup, residue and air namely can not occur can enter in the casting mold and form the phenomenon of cinder hole and the pore of foundry goods along with molten iron, has improved the quality of foundry goods.
