By penetrating sand, compacting, molding, mould assembly technical process, sand mold apperance is made, the sand mold made is transported at casting machine, etc.
It is to be cast；
D, casting solidification：Casting process uses casting machine automatic casting molten iron, and pouring temperature is controlled at 1360 DEG C -1410
DEG C, poring rate 3-5kg/s, the qualified molten iron of melting is by after full of sprue cup, running channel and riser neck, into support apperance,
Cast is completed after molten iron pours full support apperance.
Further preferably, during Metal Melting, carbon content is 3.8%, and silicone content is 2.5%, and manganese content is 0.45%, and copper contains
Measure as 0.35%
Compared with prior art, the invention has the advantages that：
(1) casting for being arranged in diverse location is simultaneously filled with die cavity, and the metallographic structure of casting and mechanical performance uniformity are good；
(2) to keep away slag effect good for running channel, and casting qualified rate is high；
(3) fill type steady, smooth, reduce sand washing defect, improve the qualification rate of casting；
(4) running channel is simply short and small, and two pieces product shares a rising head, and molten metal consumption is few, improves the yield rate of product；
(5) pour into a mould quickly, improve production efficiency；
(6) product yield ratio is compared with common runner system, and its product yield ratio can improve 5%~10%.

Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, bracket casting mixed type apparatus for pouring of the present invention, including template 1, the top of template 1 is set
Multiple support apperances 6 are set on sprue cup 2, template 1, and template 1 is connected with support apperance 6 by cross gate, and cross gate is divided into
Horizontal cross gate 3 and vertical cross gate 9, horizontal cross gate 3 are high trapezoid cross section, with slag effect is kept away well, reduce product
Slag blister, improves the qualification rate of product, and vertical cross gate 9 is standard trapezoid section, with good transmittability, improves iron
The mold-filling capacity of water, can be poured into a mould using relatively low temperature, the external rising head 4 of support apperance 6, and rising head 4 leads to support apperance 6
Cross riser neck 5 to be connected, riser neck 5 can also serve as ingate, the external horizontal cross gate 3 of rising head 4, rising head 4 and horizontal cross gate 3
It is connected by bridge piece 8, specifically, the medium position of template 1 sets vertical cross gate 9, the both sides of vertical cross gate 9 are set
Horizontal cross gate 3, the end of horizontal cross gate 3 is connected to rising head 4 by bridge piece 8, and vertical cross gate 9 passes through bridge piece 8
It is connected with the horizontal cross gate 3 of bottom, it is to avoid be poured into vertical cross gate 9 directly down, changes the dynamic of metal flow velocity
The filling velocity of pressure, effectively control molten iron.
Different running channels is played by simple overlapping mode to be kept away outside slag effect well, additionally it is possible to which control molten iron fills type
Speed, it is ensured that molten iron is simultaneously filled with eight die cavities.
Wherein, each two support apperance 6 shares a rising head 4, not only ensures the feeding demand of product, also improves product
Yield rate；Anti- striker 7 is set on 1 four jiaos of template, the situation that can not only prevent operator's maloperation from causing template 1 to damage,
Also act as the effect of withdrawing pattern guiding.
Using the bracket casting casting technique of bracket casting mixed type apparatus for pouring, comprise the following steps：
A, Making mold：Mold Making is made including template 1, and template 1 is made up of pressure plate and counter, by running channel and branch
Frame apperance 6 is made after vertical-parting processing, is arranged on positive and negative two pieces of templates 1；
B, Metal Melting：The pig iron, steel scrap, foundry returns are added into medium-frequency induction furnace according to 35%, 25%, 40% ratio
Cast iron melting is carried out, qualified molten iron is obtained, in Metal Melting, carbon equivalent high can improve the mobility of spheroidal graphite cast-iron, carbon
Equivalent is at 4.8% or so, and shrinkage porosite tendency is minimum, and by carbon content control 3.8%, silicone content is controlled 2.5%, is made full use of
Graphite convergent-divergent is to bracket casting from feeding effect, and by manganese content control 0.45%, copper content control comes 0.35%
Ensure the hardness, tensile strength, elongation percentage of product QT500-7 materials requirement；
C, moulding：By the mould installion made on DISA moulding machines, using vertical-parting box-less shoot squeeze sculpting method,
By penetrating sand, compacting, molding, mould assembly technical process, sand mold apperance is made, the sand mold made is transported at casting machine, etc.
It is to be cast；
D, casting solidification and peeling：Casting process uses casting machine automatic casting molten iron, and pouring temperature control exists
1360 DEG C -1410 DEG C, poring rate 3-5kg/s, the qualified molten iron of melting by after full of sprue cup 2, running channel and riser neck 5,
Into support apperance 6, cast is completed after molten iron pours full support apperance 6；It is casting process brimmer, continuous, make molten iron while filling
Eight die cavities of full diverse location, while making sand/slag in molten iron fully float, reduce sand/slag blister defect, due to bracket casting
