Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
As shown in Figure 1, Figure 2 and Figure 3, the utility model includes sprue cup 11, sprue 2, cross gate 3, ingate 4 and one
A casting mold type chamber 5, one end of cross gate 3 are connected to the lower end of sprue 2, and ingate 4 is connected to the other end of cross gate 3, casting
Type type chamber 5 is connected to ingate 4, and sprue 2 is in the tubular structure of upper end opening lower end closed, between sprue cup 1 and sprue 2
Equipped with connecting tube 6, the upper end of connecting tube 6 is connected to the bottom end of sprue cup 1, and the lower end of connecting tube 6 is connected with sprue 2, connection
The link position of pipe 6 and sprue 2 is higher than cross gate 3, the circular in cross-section of the inner cavity of sprue 2, connecting tube 6 and sprue
The link position of 2 inner wall is tangent, i.e. the angle of the tangent line of the tie point of the inner wall of connecting tube 6 and sprue 2 and connecting tube 6
For zero degree, the molten metal sprayed from connecting tube 6 will not vertically knock the inner wall of sprue 2, and there are certain when molten metal sprays
Speed, due to the circular in cross-section of the inner cavity of sprue 2, the inner wall of the arc of sprue 2 has guiding function to molten metal,
Make inner cavity spiral-falling of the molten metal along sprue 2, so that the molten metal in sprue 2 forms whirlpool, under the action of whirlpool,
Bubble and impurity in molten metal are climbed to the liquid level of molten metal, it is only necessary to guarantee the big of the nozzle of the lower end of connecting tube 6
Small bigger with the nozzle of the cross gate 3 of 2 link position of sprue than cross gate 3, molten metal pours into the speed ratio metal of sprue 2
Liquid flows out the speed block of sprue 2 from cross gate 3, and the liquid level of molten metal just can rapidly increase to sprue 2 in sprue 2
Top, 2 lower metal liquid of sprue flows into casting mold type chamber 5 through cross gate 3 and ingate 4, completes the molding of casting.Molten metal
Interior small concentration impurity and bubble rapidly increase to the liquid level of molten metal, and the molten metal of sprue lower part enters in casting mold type chamber 5
Molten metal bubble and impurity reduce, greatly improve the quality of casting.In other embodiments, the inner cavity of sprue 2
Cross section can also for ellipse；The angle of tangent line and connecting tube 6 at the tie point of the inner wall of connecting tube 6 and sprue 2
It can also be other angles, it is only necessary to the metal liquid that satisfaction is sprayed from connecting tube 6 will not vertically hit the inner wall of sprue 2,
Molten metal is in the non-perpendicular inner wall for hitting sprue 2, and after shock, molten metal still has one along sprue 2
The tangential component velocity of the point of impingement of wall, still can under the guidance of 2 inner wall of sprue spiral-falling, and form whirlpool；Casting mold
The quantity of type chamber 5 can also be other quantity.
As shown in Fig. 2, the nozzle of the lower end of connecting tube 6 is necking 7 as specific embodiment.That is the pipe of 6 lower end of connecting tube
Mouth reduces, in the identical situation of pressure at nozzle of the molten metal in connecting tube 6 to the lower end of connecting tube 6, from connecting tube 6
The speed for the molten metal that the nozzle of lower end sprays increases, and keeps the intensity of the whirlpool in sprue 2 bigger, makes the bubble in molten metal
The speed risen with small concentration impurity is faster.
As shown in Fig. 2, as specific embodiment, in flat, the height of the necking 7 is greater than necking 7 for the necking
Width.The one side of the molten metal of ejection and the inner wall of sprue 2 are tangent, the molten metal closer to the molten metal other side of ejection
Angle with the inner wall of sprue 2 is closer to 90 degree, and the collision with the inner wall of sprue 2 is closer to head-on crash, molten metal
Be depleted reduction speed it is bigger, it is just smaller in the tangential component velocity of the point of impingement of the inner wall with sprue 2, formed whirlpool
Intensity it is just smaller；And necking 7 in the case that the height of necking 7 is greater than the width of necking 7, is sprayed from necking 7 in flat
The thinner thickness of molten metal, the side of the molten metal of ejection and the inner wall of sprue 2 are tangent, the other side of the molten metal of ejection with
The molten metal side tangent with sprue 2 is closer, and keeps the other side of molten metal and the angle of the inner wall of sprue 2 more inclined
From 90 degree, make molten metal and sprue 2 more deviate head-on crash, molten metal be depleted reduction speed it is smaller, pouring with erecting
The tangential component velocity of the point of impingement of the inner wall in road 2 is bigger, and whirlpool intensity is bigger, can make more quickly small close in molten metal
Spend impurity and bubble floating.
As shown in figures 1 and 3, as specific embodiment, the upper end lid 8 of sprue 2, lid 8 is for closing sprue 2
Upper end, poly- slag pipe 9 is equipped on lid 8 upwards, the diameter of poly- slag pipe 9 is smaller than the diameter of sprue 2, poly- slag pipe 9 and sprue 2
Concentric setting.Bubble and small concentration impurity meeting when the molten metal in sprue 2 rises in poly- slag pipe 9, in molten metal
Enter poly- slag pipe 9 under the action of whirlpool and buoyancy, forms metal column after molten metal solidification, since the diameter of poly- slag pipe 9 is small,
The metal column in the lower lesser poly- slag pipe 9 of diameter is more easily cut, to be easier to remove impurity.
As shown in figure 3, the bottom of the sprue is " U "-shaped, the coupling part of the cross gate and sprue is higher than perpendicular
The " U "-shaped part of running channel.Molten metal in sprue 2 falls into the bottom of sprue 2, and the bottom of sprue 2 is horizontal to inflow to pour
Molten metal before road 3 plays the role of buffering, keeps the flow velocity of the molten metal flowed into cross gate 3 more stable, plays current stabilization
Effect.
The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
