Description
Technical Field
The utility model belongs to brake drum casting field, concretely relates to shell type casting brake drum gating system.
Background
The method mainly comprises the steps of setting or not setting a riser, filling molten iron, filling and feeding, wherein shrinkage cavities and shrinkage porosity exist in products with different degrees, and meanwhile, the products are easy to break when a pouring system is removed, so that the cast body is prevented from being damaged, and in addition, residues exist during pouring to influence the product quality.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a shell type casting brake drum gating system adopts the top notes formula casting process, and the die joint design does benefit to the molten iron and fills the type and the feeding at the top, and it is steady to adopt semi-enclosed gating system to make the molten iron fill the type, and the cross gate height is 1.1-1.25 times of the flange of foundry goods and is favorable to the foundry goods to realize that order solidifies and feeding, and interior runner department designs little inclined plane formula stress groove, from this department fracture and avoid destroying the foundry goods body easily when being convenient for get rid of gating system.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a shell type casting brake drum gating system, includes pouring basin, sprue, cross gate and ingate, the pouring basin with sprue integrated into one piece, set up the pouring hole of infundibulate on the pouring basin, the pouring hole with the sprue communicates with each other, the bottom of sprue is provided with the pouring basin, the bottom intercommunication of sprue has three the cross gate, the cross gate intercommunication has a plurality of ingates, the ingate communicates with the inner chamber of section mould.
Preferably, the pouring system further comprises a circular ceramic filter plate, and the ceramic filter plate is mounted in the middle of the sprue and used for avoiding slag.
Preferably, the height of the cross gate is 1.1-1.25 times of the flange of the casting.
Preferably, a small inclined plane type stress groove is formed at the communication position of the inner sprue and the inner cavity of the section mould.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses a top notes formula casting process, the die joint design is at the top, do benefit to the molten iron and fill type and feeding, it is steady to adopt semi-enclosed gating system to make the molten iron fill the type, the cross gate height is 1.1-1.25 times of foundry goods flange, do benefit to foundry goods realization order and solidify and feeding, little inclined plane formula stress groove of design of ingate department, easy fracture from this point and avoid destroying the foundry goods body when getting rid of gating system, the pouring basin is as an organic whole with the design of sprue, the centre is placed circular ceramic filter piece and is used for keeping away the sediment, the sprue nest of sprue bottom design orthodrome, make the molten iron can cushion after falling down from the eminence and avoid the gassing.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a shell type casting brake drum gating system comprises a sprue cup 1, a sprue 2, a cross gate 3 and an inner gate 4, wherein the sprue cup 1 and the sprue 2 are integrally formed, a funnel-shaped pouring inner hole 5 is formed in the sprue cup 1, the pouring inner hole 5 is communicated with the sprue 2, a sprue pit 6 is formed in the bottom of the sprue 2, the cross gate 3 is communicated with a plurality of inner gates 4, and the inner gates 4 are communicated with an inner cavity 8 of a section mold.
The pouring system also comprises a circular ceramic filter plate 7, wherein the ceramic filter plate 7 is arranged in the middle of the sprue 2 and used for avoiding slag.
The height of the cross pouring channel 3 is 1.1-1.25 times of the flange of the casting.
And a small inclined plane type stress groove is formed at the communication part of the inner sprue 4 and the inner cavity 8 of the section mould.
The principle of the utility model is as follows:
the inner sand shell 9 and the outer sand shell 10 are positioned and sealed through the seam allowance, molten iron is poured from the sprue cup 1, is filtered through the ceramic filter sheets 7 in the sprue 2 to avoid slag, is buffered through the sprue pit 6, enters the inner cavity 8 of the section die through the cross gate 3 and the inner gate 4, and is solidified by filling the section die from bottom to top. After the inner cavity 8 of the mould is filled with molten iron, the self-feeding of the casting from top to bottom is realized by the dead weight, and the feeding is carried out on the upper flange part of the casting by the pressure of the higher cross gate 3 and the pouring cup 1.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement, component separation or combination made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
