Degree, while also it is highly detrimental to the exhaust and impurities removal of casting afterbody.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is that the casting die with flow structure, its
It can solve the problem of prior art casting head and tail temperature differs greatly, influences the intensity of casting.
The purpose of this utility model is realized using following technical scheme：
A kind of casting die with flow structure, including die ontology, the die ontology include sprue cup, runner pipe
Road, large-scale mold cavity and comb, sprue cup connect the front end of circulation duct, and the upper end of the large-scale mold cavity, which is equipped with, divides cast gate,
Divide the end of cast gate connection circulation duct；Riser is additionally provided with the side wall of the large-scale mold cavity, which connects with comb.
Further, to be multiple, all points of cast gates are all connected with circulation duct to the cast gate that divides set in the large-scale mold cavity
End, and all points of cast gates in large-scale mold cavity are equal with the distance between the end of circulation duct.
Further, the circulation duct has multiple branch pipes, the quantity of large-scale mold cavity and the quantity phase of the branch pipe
Together, and large-scale mold cavity connects one to one with branch pipe；All points of cast gates and corresponding branch pipe in each large-scale mold cavity
The distance between end is equal.
Further, the upper surface for dividing cast gate to be arranged on large-scale mold cavity one end, it is large-scale that the riser is arranged on this
Mold cavity is remote to divide on the side wall of the other end of cast gate.
Further, the comb is also connected with an accumulator tank, and filter is equipped between the comb and accumulator tank.
Further, the filter is ceramic filter.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is by Feeder Design, when molten iron is constantly injected from sprue cup, overflows after reaching riser height from riser
Go out, since molten iron ceaselessly injects so that the head temperature of casting be kept substantially with tail temperature it is consistent, be not in casting
Part size is long, also bad to influence the intensity of casting, while facilitates the exhaust and impurities removal at each position.

Embodiment
In the following, with reference to attached drawing and embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment：
As depicted in figs. 1 and 2, in the present embodiment, there is provided a kind of casting die with flow structure, it includes mould sheet
Body, the die ontology include sprue cup 1, circulation duct 2, large-scale mold cavity 3 and comb 4, and sprue cup 1 connects circulation duct 2
Front end, the upper end of the large-scale mold cavity 3, which is equipped with, divides cast gate 31, divides cast gate 31 to connect the end of circulation duct 2；It is described large-scale to pour
Riser 32 is additionally provided with the side wall of mold cavity 3, which connects with comb 4.Sprue cup 1 is of virtually corresponding two and opens
Mouthful, in use, molten iron is irrigated from sprue cup 1, circulation duct 2 is circulated to, and by dividing cast gate 31 to enter to large-scale mold cavity
3, when the molten iron in large-scale mold cavity 3 will be overflowed more than the height of riser 32 from riser 32 and be discharged from comb 4, molten iron is continuous
Perfusion try one's best, the molten iron in large-scale mold cavity 3 constantly overflows, and has ensured that the temperature at each position of casting is basically identical, convenient
The exhaust and impurities removal at each position, will not long local temperature occur too low and influence the intensity of casting because of casting dimension.
Embodiment one：
As shown in figure 3, in the present embodiment, cast gate 31 is divided to be multiple, all points of cast gates 31 by what is set in large-scale mold cavity 3
The end of connection circulation duct 2 is all connected with, divides cast gate 31 to connect by the end of other pipeline and circulation duct 2 in force
Connect.All points of cast gates 31 in large-scale mold cavity 3 are equal with the distance between the end of circulation duct 2.Cast gate 31 is divided to correspond to greatly
The different position of type mold cavity 3, molten iron is separately flowed into by multiple points of cast gates 31, due to dividing cast gate 31 to arrive the end of circulation duct 2
End is apart from molten iron injection basic synchronization that is identical, therefore can ensureing large-scale 3 diverse location of mold cavity so that casting head temperature
It is kept substantially with tail temperature consistent.
To realize superior technique effect, circulation duct 2 has multiple branch pipes 21, the quantity of large-scale mold cavity 3 with it is described
The quantity of branch pipe 21 is identical, and large-scale mold cavity 3 connects one to one with branch pipe 21；It is all in each large-scale mold cavity 3
Divide cast gate 31 equal with the distance between corresponding 21 end of branch pipe.
That is, the quantity of the large-scale mold cavity 3 in the present embodiment might not only have one, can be it is multiple, together
When be molded multiple casting, production efficiency higher.
Embodiment two：
As shown in figure 4, in the present embodiment, cast gate 31 is divided to be arranged on the upper surface of large-scale 3 one end of mold cavity, riser 32 is set
In the large-scale mold cavity 3 away from the side wall of the other end for dividing cast gate 31.Since large-scale mold cavity 3 is used to be molded heavy castings,
Its volume is larger, and the temperature difference of casting head and afterbody is excessive so as to influence the yield of casting in order to prevent, wherein one end
Setting divides cast gate 31, and in addition opposite one end sets riser 32, and one end is equivalent to front end among these, and other end is equivalent to tail
End, constantly injects molten iron in front end, and in rear end, molten iron exceedes a certain amount of spilling automatic afterwards.
In addition in the present embodiment, comb 4 is also connected with an accumulator tank 5, and filter 6 is equipped between the comb 4 and accumulator tank 5.
The molten iron of spilling is flowed into pass in and out in accumulator tank 5 by comb 4 and stores, and filter 6 is first passed through before storage and is filtered, except impurity elimination
Stored again after matter, to facilitate recycling to use, do not cause to waste and pollute.Filter 6 is preferably ceramic filter, it has good
Heat resistance.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
