Abstract
The utility model provides a pouring structure. The pouring structure comprises a pouring gate, a spure, a runner, a feeder head and a cavity, wherein the cross section of the structure of at least part of cavity is of a flat structure, and the flat structure in the cavity is communicated with the runner through a flat connecting runner. The feasible pouring structure is provided for castings with strip structures in reality; the runner with the strip structure is used for solving the problem of impact of pouring liquid on the cavity during pouring and is particularly suitable for using in the cavity with the strip structure; and the pouring liquid has a relatively high buffer effect in the connecting rubber with the strip structure, so that the pouring liquid can stably enter the cavity, the impact on the cavity is effectively avoided, and the defects such as sand inclusion are prevented from occurring.
Description
Technical field
The utility model relates to casting field, relates to specifically a kind of cast structure.
Background technology
In conventional cast structure, enter straight channel through an adapter cavity at potting syrup by cast gate, and then have multiple cross gates to enter die cavity just can to have poured into a mould, but in actual casting process, engineer will carry out some necessary particular design to running channel according to various concrete foundry goods, such as, at the flat structure place of foundry goods, while using conventional cross gate, potting syrup impacts larger to die cavity wall, easily cause the defects such as burning into sand, therefore need special cast structure could realize more satisfactory cast effect.
Utility model content
Technical problem to be solved in the utility model is, a kind of cast structure that the flat structure in large foundry goods is poured into a mould of being suitable for is provided.
For solving the problems of the technologies described above, the cast structure that the utility model provides, it comprises cast gate, sprue, cross gate, rising head and die cavity, and the cross section of the structure of die cavity is flat structure at least partly, and the running channel that is connected through flat between the flat structure in die cavity and cross gate is communicated with.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
Provide a kind of feasible cast structure for thering is the foundry goods of rectangular structure in reality, solving by the running channel of rectangular structure is the impact of potting syrup to die cavity in cast, be particularly suitable for using in the die cavity with rectangular structure, potting syrup has higher buffering effect in the connection running channel of rectangular structure, make potting syrup can enter into very stably die cavity, effectively avoid the impact to die cavity, avoid occurring the appearance of the defects such as burning into sand.
As improvement, die cavity also comprises that roof is the cavity of arc, roof is that the cavity of arc is communicated with flat structure, roof is the transition running channel that is provided with annular between the cavity of arc and cross gate, transition running channel is communicated with cross gate 3, the cavity that transition running channel is arc through multiple ingates with roof is communicated with, and multiple ingates are circumferentially uniformly distributed along transition running channel.Roof is the cavity structure of arc the washing away of liquid also will consider to pour into a mould in when cast time, therefore, arranges after annular transition running channel cushions and has ingate to be communicated with cast again according to himself feature, can effectively reduce washing away die cavity wall.
As further improvement, the connection running channel of described flat is provided with horizontal kink.On the basis of rectangular structure, cushion bending structure is further set, reduce the flowing velocity of liquid, further reduce liquid to the washing away of die cavity wall, can effectively reduce the generation of the defects such as burning into sand.

Fig. 1 is the structural representation of the utility model cast structure;
Fig. 2 is the structural representation of another angle of the utility model cast structure;
Fig. 3 is the utility model cast structure partial structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, Fig. 2, Fig. 3, the utility model cast structure, it comprises cast gate 1, sprue 2, cross gate 3, rising head 4 and die cavity 5, cast gate 1 is communicated with sprue 2, cross gate 3 is communicated with sprue 2, rising head 4 plays permeation functions, and these are all the common structures possessing in conventional cast structure, in the utility model, also have.
Wherein, in die cavity 5, the cross section of the structure of die cavity 5 is flat structure 5.1 at least partly, and the running channel 6 that is connected through flat between flat structure 5.1 and cross gate 3 is communicated with.This structure is applicable to having in a lot of heavy castings in the die cavity of flat structure and uses, and the connection running channel 6 of rectangular flat can play good cushioning effect, and flow rate of liquid is wherein slower, also just less to washing away of die cavity wall.Further improved procedure is, is provided with horizontal kink 10 at the connection running channel 6 of described rectangular flat, and this kink 10 belongs to further optimization, plays cushioning effect.
According to concrete foundry goods, in the utility model, die cavity 5 also comprises that roof is the cavity 7 of arc, roof is that the cavity 7 of arc is communicated with flat structure 5.1, roof is the transition running channel 8 that is provided with annular between the cavity 7 of arc and cross gate 3, transition running channel 8 is communicated with cross gate 3, the cavity 7 that transition running channel 8 is arc through multiple ingates 9 with roof is communicated with, and multiple ingates 9 are circumferentially uniformly distributed along transition running channel 8.Circumferentially be uniformly distributed the circulation that is conducive to liquid, pour into a mould also more evenly, belong to reasonable setting, transition running channel 8 is wherein also to play cushioning effect, also can reduce the impact of potting syrup to die cavity.
