Abstract
The utility model belongs to the technical field of casting, and particularly relates to a pouring cup for a high-filling pressure head. According to the pouring cup, a pouring metal solution is saved, and the filling pressure is increased. An archy structural member (5) is arranged in a space of the pouring cup and positioned between two direct pouring openings of the pouring cup; two ends of the archy structural member (5) are welded with the front side face and the rear side face of the pouring cup; the lower space of the pouring cup is divided into two spaces; the archy structural member (5) is lower than the pouring cup; and due to the size of a space occupied by the archy structural member (5), the residual space of the pouring cup meets a requirement of a casting for a metal liquid amount.
Description
Technical field
The utility model belongs to casting technology field, is specifically related to a kind of high type pressure head cup that fills.
Background technology
Cup is the device that is used for sand casting, permanent mold casting aluminium alloy castings cast usefulness, and the effect of cup is the molten metal of accepting from casting ladle, the purpose that reaches the control of capacity, flow and steadily fill type through cup.The version of cup has direct influence to the quality of foundry goods, and is more obvious to the influence of large thin-wall housing class foundry goods especially.
Existing cup casting state position is as shown in Figure 1, foundry goods length * wide * high (1358 * 435 * 265) mm, and average wall thickness is 5mm, adopts two sprues cast of a cup, comprises cup 1, junner bush 2, upper mold 3 and lower mold 4 among the figure.Cup adopts the 5mm steel plate to be welded, and cup bottom surface and side weld together, and opens wide above, and floor space is little, and upward area is big, is inverted trapezoidal structure, adopts a casting ladle cast during cast, once can pour into a mould a plurality of foundry goods.
In order to improve the mold-filling capacity of molten metal; Reduce generation of defects such as misrun, cold shut; A kind of method is by adding junner bush, improving the existing height of cup above upper mold 3 and realize that junner bush is processed with resin sand; Junner bush is placed on upper mold down gate place, and the aperture of junner bush is consistent with cup down gate aperture.Fill the type pressure head though this method has improved, when raising the cup height, cup apart from lower mold bottom surface drop also along with increase; Caused the drop of molten metal to strengthen during cast; Generation is splashed, thereby produces a large amount of oxide slag inclusions, has increased the percent defective of foundry goods.
Another kind method is not raise the existing height of cup on upper mold; But utilize the quantity delivered that increases alloy liquid, make the alloy liquid level in cup, be in the higher position all the time, to increase mold filling pressure; Though this method has reduced the generation probability of splashing of molten metal and oxide slag inclusion; But must keep the molten metal in the cup to be in a high position in the casting process always, could guarantee that there are enough mold-filling capacity in the later stage of cast, but cause the waste of molten metal like this.
The utility model content
The utility model provides a kind of high type pressure head cup that fills; At the height of not raising the relative upper mold of cup; Do not increase under the prerequisite of quantity delivered of molten metal yet, make and fill the type overall process and keep higher mold filling pressure always, even when foundry goods fills type later stage molten metal and reaches upper surface or the most significant end of foundry goods; Also can keep the higher type pressure head that fills, promptly improve mold filling pressure.
The technical scheme of the utility model is that a kind of high type pressure head cup that fills, this cup adopt steel plate to be welded; Cup bottom surface and side weld together, and open wide above, and floor space is little, upward area is big; Be inverted trapezoidal structure; It is characterized in that: a domes spare is set in the cup space, and the cross section of domes spare is an arch, and domes spare is between two down gates of cup; Two sides weld together before and after the two ends of domes spare and the cup; The cup lower space is divided into two spaces, and the height of domes spare is lower than the cup height, and the domes spare size that takes up space guarantees that the cup remaining space satisfies the required metal liquid measure of foundry goods.
Said domes spare adopts the 5mm steel plate to be welded.
The cross section of said domes spare adopts trapezoidal or triangle
The beneficial effect of the utility model is: occupy-place structure in the middle of the utility model adopts; And the size of occupy-place volume changes the volume of cup in the middle of utilizing, and makes the utilization rate of molten metal reach maximum, has improved and has filled the type pressure head; Promptly improve mold filling pressure, reduced the molten metal waste.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the utility model height fills type pressure head cup casting state position sketch map;
Fig. 4 is the vertical view of Fig. 3.
Wherein: cup 1; Upper mold 3; Lower mold 4; Domes spare 5.
The specific embodiment
Like Fig. 3, shown in Figure 4, the utility model is the occupy-place method in the middle of adopting on the basis of existing cup, and promptly cup adopts steel plate to be welded; Cup bottom surface and side weld together, and open wide above, and floor space is little, and upward area is big; Be inverted trapezoidal structure, a domes spare 5 is set in the cup space, the cross section of domes spare 5 is an arch; Domes spare 5 is between two down gates of cup; Two sides weld together before and after the two ends of domes spare 5 and the cup, and the cup lower space is divided into two spaces, are equivalent to form two independently cups; The height of domes spare 5 is lower than the cup height, and 5 of the domes spares size that takes up space guarantees that the cup remaining space satisfies the required metal liquid measure of foundry goods and gets final product.Domes spare 5 adopts the 5mm steel plate to be welded.Occupied by domes spare 5 owing in the middle of the cup during cast; Molten metal is full of the space, both sides of cup earlier; Under the constant situation of molten metal total amount, the liquid level that this cup forms is than the liquid level raising of existing cup, pouring into a mould the later stage when metal bath surface and foundry goods upper surface drop reduce; Only need to keep the height of both sides cup inner metal liquid; Fill the type pressure head and just can be guaranteed, promptly guaranteeing under the identical mold filling pressure condition, existing relatively cup is saved the molten metal of domes spare 5 volumes size.
The cross section of domes spare 5 adopts trapezoidal or triangular structure.
