Detailed description of the invention
It is the knot of one specific embodiment of this utility model with reference to Fig. 3 to Fig. 5, Fig. 3 to Fig. 5
Structure schematic diagram, as it can be seen, a kind of be applied to nut casting pouring gate structure, including die cavity 1,
Ingate 2, cross gate 3, sprue 4, during casting, molten metal enters by sprue 4,
Distribution flows in cross gate 3, then injects die cavity 1 through ingate 2, and described die cavity 1 is with interior
Running channel 2 junction is ingate, and described cross gate 3 is runner gate with ingate 2 junction,
Area of section at described runner gate is more than the area of section at ingate.
As preferably, described ingate 2 include the cast section 21 that is connected with die cavity 1 and with
The liquid input section 22 that cross gate 3 connects, the sectional area of described cast section 21 is more than liquid input section 22
Sectional area so that the cast molten metal volume that can accommodate of section 21 can more than liquid input section 22
Accommodate molten metal volume, postpone the rate of cooling of ingate 2, make molten metal to foundry goods die cavity 1
Interior liquid cooling has the prolongation of abundance, it is achieved eliminate shrinkage cavity and porosity defect, it is not necessary to cold
Ferrum processes and arranges, saves a large amount of frock expense, eliminates because of the issuable pore of chill
Class defect, casting qualified rate is up to 100%.
As preferably, the structure (position, corner as it can be seen, described ingate 2 cross section is square
Carry out fillet process), described cast section 21 is smoothed by a curved surface or inclined-plane with liquid input section 22
Transition, prevents the sudden change of ingate 2 shape from affecting the conveying of molten metal, described cast section 21
2 times to 4 times of the sectional area that sectional area is liquid input section 22, cast section 21 and liquid input section
The same length of 22 so that the molten metal volume that described cast section 21 can accommodate is for entering
Liquid section 22 can accommodate 2 times to 4 times of molten metal volume, produces and process of the test concrete
In, the molten metal volume that can accommodate in cast section 21 is that liquid input section 22 can accommodate molten metal
When 2 times of volume are to 4 times, the molten metal rate of cooling of ingate 2 substantially with the gold of die cavity 1
Belong to liquid rate of cooling roughly the same, it is possible to when the effective molten metal supplemented in die cavity 1 cools down
Shrink room, it is achieved eliminate shrinkage cavity and porosity defect.
In nut structure in the present embodiment, preferably by the sectional area of described cast section 21
Being generally configured as 3 times of sectional area of liquid input section 22, the most described cast section 21 can accommodate
Molten metal volume is 3 times that liquid input section 22 can accommodate molten metal volume, now, Ji Kejie
Save the molten metal in ingate 2, ensure that the quality of foundry goods, reach optimal economy and matter
Control benefit.
In the present embodiment, die cavity 1 one type prepares six, is symmetrically distributed in cross gate about 3
Both sides, to improve the efficiency produced.
In the present embodiment, for the nut structure shown in figure, cast section 21 can be held
The molten metal volume received is set to liquid input section 22 can accommodate 2 times to 4 times of molten metal volume,
Preferably 3 times, in concrete implementation process, can be according to the concrete shape of product die cavity and body
The long-pending volume that cast section 21 and liquid input section 22 are set, if the volume of cast section 21 be more than into
The volume of liquid section 22 can realize postponing the effect of the rate of cooling of ingate 2, does not makees at this
Describe in detail.
Above preferable enforcement of the present utility model is illustrated, certainly, this
Utility model can be familiar with this area to use form different from the embodiment described above
Technical staff in the conversion of the equivalent made on the premise of spirit of the present invention
