The like product of current traditional handicraft casting, using 2-3 rising head technique, yield rate is 38% or so, percent defective
6% or so, each independent core of product.Cast-internal shrinkage porosite is required beyond Customer Standard, it is necessary to which 100% detects a flaw, not only simultaneously
Often complain by client, while also result in the significant wastage of company's productive labor cost；
It is therefore desirable to design a kind of new i.e. guarantee product quality, improve product yield, rate of reducing the number of rejects and seconds, can carry again
The housing mould running gate system of high production capacity.
The content of the invention
Technical problem：A variety of deficiencies of prior art in view of the above, the technical problem to be solved in the present invention is to carry
For a kind of sand mould structure pour mass of automobile steering system knuckle, using single rising head technique, core is shared, product is not only met
Internal porosity requirement, improves product yield, and rate of also reducing the number of rejects and seconds improves production efficiency.
Technical scheme：In order to achieve the above objects and other related objects, the present invention provides a kind of automobile steering system and turned to
The sand mould structure pour mass of section, the pour mass includes sand mold body, casting die cavity, rising head, ingate, cross gate, sprue, poured
Cup, core；Six casting die cavities are provided with the sand mold body, six casting die cavity combination of two are 3 groups of casting groups, often
The individual casting die cavity is connected with a rising head and an ingate respectively, is put between two casting die cavities of every group of casting group
A shared core is put, the rising head is connected using bottom filling connection with ingate, and all ingates are connected with a cross gate,
Cross gate sets 2 filters with sprue transition position, and the sprue is connected with sprue cup, and all running channels use overlapping mode
Buffer molten iron.
Preferably, the rising head is connected by rising head neck structure with casting die cavity.
Preferably, the ingate is connected with rising head bottom filling overlapping mode, and the choked flow sectional area of ingate is：FIt is interior=
143+92mm2。
Preferably, the choked flow sectional area of the cross gate being connected with single group ingate is：FIt is horizontal=309mm2。
Preferably, the choked flow sectional area of the sprue is：FDirectly=1256mm2。
Preferably, 2 66*66*12.5mm foam ceramic filter is used between the cross gate and sprue, rod is directly poured straight
Footpath 40mm.
Beneficial effect：By above technical scheme, the present invention has following technique effect compared to prior art：
The sand mould structure pour mass for the automobile steering system knuckle that the present invention is provided only has 1 on each sand mold body
Rising head, can meet the internal porosity of casting under the premise of rising head as few as possible, while also improving product yield to about
50%；Rising head is connected with ingate using bottom filling, and running channel buffers molten iron using overlapping mode, reduces sand washing risk, and reduction is useless
Product rate is to about 3%；And every 2 cave shares 1 core, reduces cost.
Brief description of the drawings
Fig. 1 is the sand mould structure injection system structure schematic diagram of automobile steering system knuckle of the present invention.
Fig. 2 is sprue, structural representation at sprue cup in the present invention.
Have in figure：Sand mold body 1, casting die cavity 2, rising head 3, ingate 4, cross gate 5, sprue 6, sprue cup 7, core
8。
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
Refer to Fig. 1.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to coordinate
Content disclosed in specification, so that those skilled in the art understands and reads, is not limited to the present invention enforceable
Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size,
Do not influence under effect of the invention that can be generated and the purpose that can reach, all should still fall in disclosed technology contents
Obtain in the range of covering.
As shown in figure 1, the sand mould structure pour mass of the automobile steering system knuckle of the present invention, including sand mold body 1, casting
Part die cavity 2, rising head 3, ingate 4, cross gate 5, sprue 6, sprue cup 7, core 8；Six casting are placed with sand mold body 1
Die cavity 2, six combination of two of casting die cavity 2 are three groups, and each combination shares a core 8, and each casting die cavity 2 sets two
Ingate 4.Each casting die cavity 2 is respectively communicated with a rising head 3, and rising head 3 is connected using bottom filling with ingate, according to calculating
