2, this utility model dead head is joined directly together with point running channel and die cavity, and dead head temperature is high, and casting temperature is low, meets consecutive solidification, beneficially the feeding of foundry goods, and processing rear flange does not has pore, improves the yield rate of foundry goods, and casting cleaning is convenient.
3, this utility model dead head is loop configuration, and along the edge extension of die cavity upper surface, dead head top is provided with air discharge duct, can effectively aerofluxus and feeding in casting process, achieve the consecutive solidification of foundry goods, and then improve the properties after formed product, and improve yield rate.
4, arranging core in this utility model die cavity, core is hollow-core construction, and core is in communication with the outside through dead head, can quickly discharge a large amount of gases that core produces in casting process.
5, this utility model divides the cross-sectional area cross-sectional area more than sprue of running channel, and a point running channel cross-sectional area is incremented by from top to bottom, after the most this structure is arranged, make fused solution when cast can more quick and stable fill type, reduce aluminum liquid oxidation to improve properties and the yield rate of product further.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1；
Wherein, 1-pouring slot, 2-sprue, 3-divides running channel, 4-dead head, 5-die cavity, 6-lower camber side, and 7, core, 8, air discharge duct.
Detailed description of the invention
Below in conjunction with accompanying drawing and this utility model specific embodiment, the technical solution of the utility model is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, a kind of pouring gate structure of aluminium alloy tubulose flanged foundry goods metal gravity casting mold, including die cavity 5, running channel, pouring slot 1, dead head 4 and core 7, wherein, running channel includes sprue 2 and point running channel 3, sprue 2 upper end is connected with pouring slot 1, sprue 2 lower end is connected with point running channel 3 upper end, dividing running channel 3 is arc running channel, and the radian of the lower camber side 6 of arc running channel is 50～60 °, in the present embodiment, the radian of lower camber side 6 is 60 °, running channel 3 is divided to be set to two, running channel 3 lower end is divided to be connected with dead head 4 side, dead head 4 lower end is connected with die cavity 5, dead head 4 is loop configuration, the top of dead head 4 arranges air discharge duct 8；Arranging core 7 in die cavity 5, core 7 is in communication with the outside for hollow-core construction and through dead head 4.
As it is shown in figure 1, two die cavities 5 share a sprue 2, so can ensure that the fused solution temperature of two die cavity 5 cast is identical, casting quality is stable, can also realize mould two chamber, two, a type simultaneously, and product yield is high, and production efficiency is higher.Fused solution enters sprue 2 from horn-like pouring slot 1, horn-like pouring slot 1 is conducive to the inflow of fused solution, the cross section of sprue 2 is circular, sprue 2 lower end connects point running channel 3 of two arcuate structures, divide running channel 3 cross-sectional area the mildest being incremented by, divide the cross-sectional area cross-sectional area more than sprue 2 of running channel 3, fused solution can effectively reduce, when sprue 2 enters and divides running channel 3, the fused solution impact velocity caused due to height fall, point running channel 3 of trapezoidal cross-section, can realize fused solution quick and stable fills type, the design dividing running channel 3 can well reduce flow velocity and the impulse force of fluid, decrease the volume gas phenomenon in cavity filling process.Fused solution enters in die cavity 5 from point running channel 3 lower end by the dead head 4 of loop configuration, die cavity 5 is first filled, rear fused solution is full of the dead head 4 of annular, owing to dead head 4 is directly connected to point running channel 3 and die cavity 5, be equivalent to cast gate and rising head shares so that dead head 4 temperature is high, in die cavity 5, casting temperature is low, realize the feeding of the consecutive solidification of foundry goods, beneficially foundry goods, improve the feeding efficiency of dead head.And a large amount of gases that core 7 produces quickly are discharged from the cope print of core 7, gas in die cavity 5 is discharged from air discharge duct 8 and core 7 gap of dead head 4 above, for the existing mode being expelled directly out, the compactness of foundry goods is good, redundant structure will not be formed at cast(ing) surface, do not have pore to occur after Mechanical processing of casting, improve casting yield.Finally, being cooled into strand, the dead head 4 on excision strand i.e. obtains intact foundry goods, and casting cleaning is convenient.
