With reference to the accompanying drawings and detailed description this utility model is further described：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, a kind of horizontal parting line running gate system of automobile brake pincers, including for pouring into the cup of molten iron
1st, the sprue 2 for connecting with cup bottom and the cross gate 3 connected with sprue bottom, in the longitudinal direction of cross gate axis
Both sides symmetric arrays have two rows, a three row die cavity, and two die cavities of horizontal first row are vertically symmetrical to arrange 11, horizontal secondary series and the
Four die cavity horizontal symmetry of three row arrange 12, and the horizontal first end of the cross gate is connected with the first ingate 7, and described first
Ingate is connected with the first rising head 9, and first rising head 9 is connected with two vertically symmetrical die cavities, and horizontal the of the cross gate
Two ends are respectively connected with second ingate 6 in longitudinal both sides, and longitudinal port part of second ingate extends to secondary series
And the 3rd between row die cavity and be connected with the second rising head 8, first rising head is connected with secondary series and the 3rd row die cavity, the horizontal stroke
The both lateral sides of running channel are respectively equipped with the first filtration bar 4 and second and filter bar 5, respectively with the first ingate 7 and second in
Running channel 6 is connected.
Above-mentioned technical proposal, two product die cavities share a rising head, are distributed by product different directions, are taken full advantage of
Die space, effectively improves the product yield of running gate system.Meanwhile, by calculating cutting for appropriate design running gate system each several part
Area, it is ensured that the filling mould states and filling velocity of left and right die cavity, riser feeding meet the principle of Equilibrium Solidification, riser feeding distal end
Position, temperature compares that cast gate position is low, by magnesium iron from the principle of feeding complete local thermal center from feeding, caliper is main
Cylinder holes position by arrange rising head complete feeding, be prevented effectively from the generation of internal defect in cast.
The both lateral sides of the cross gate are provided with the first filtration bar 4 and second at close sprue position and filter bar 5,
For aiding in resistance slag, can effectively simplify Design of Runner System, while the filtering residue and steady flow result by filter, reduces foundry goods slag
The generation of scar and blister sand.
The caliper data that this utility model specific embodiment is related to are as follows：Casting weight is 2.35kg, and long * width * is high
167*140*86, template size 500*600；Running gate system calculating is carried out as follows：
Riser calculating：Shared rising head 9 is identical with the diameter dimension of rising head 10, is connected with running gate system, therefore emits for heat
Mouthful, rising head diameter is calculated according to product modulus：Product modulus be 0.42cm (modulus=volume/surface area), feeder modulus
>=product modulus * 2*1.5=0.84, calculate rising head diameter >=feeder modulus * 4*10=Ф 50.4mm.Because of rising head feeding two simultaneously
Individual product, therefore, rising head diameter and height are suitably amplified, and feeding effect is tested by running gate system mold filling simulation
Card, it is it is determined that a diameter of Ф 55mm of final rising head, riser height >=55*1.5=82.5mm, it is considered to foundry goods height itself, final to select
90mm is taken, higher than foundry goods 37.5mm.
Running channel is calculated：This running gate system fills type using semi-enclosed, need to preferentially calculate minimum captured area.Choked flow sectional area
Hydro science formula：S resistance=m/ [ρ T μ (2gHp)1/2]；
M poured weights, it is 2.35*6/0.6=to calculate theoretical poured weights according to product weight and expected yield rate
23.5kg；
ρ cast iron density of liquid phase, takes 0.007kg/cm3；
The T durations of pouring, according to formulaG=m, μ ' according to I water tender horizontal line magnesium iron cast empirical value be
1.6～1.8；Quickly fill type μ ' and take 1.6, calculate
μ choked flow coefficients, this technique are to fill type technique in the middle of green-sand, and μ takes 0.5；
Hp fall heads, [H emits Hp=Ho-2/ (C+H emits-P)]1/2, Ho- mo(u)ld top halves height, C- foundry goods height, P- foundry goods mo(u)ld top halves
Height, calculates Hp=140- [902/(86+90-52.5)]1/2=10.7cm；
Calculate S and hinder=23.5/ (0.007*7.75*0.5* (2*980*10.7)1/2)=597mm2；
By the S resistances for calculating, sprue size needed for inverse, enlarged running system sprue：Captured area
=1:0.85, sprue area 597/0.85=702.4 is calculated, therefore chooses Φ 30 and directly pour rod；
According to sprue：Cross gate：Ingate：Captured area (ingate end)=1:1.5：1.2:0.85, count respectively
Cross gate and ingate is calculated, because being two die cavities on the left of product slates, right side is four die cavities, therefore to shunting cross gate 3 or so
Effluent amount is allocated, and 3 right side sectional area of setting cross gate is 2.2 times of left side cross-sectional product, calculates left side cross-sectional product 330mm2,
Right side sectional area 726mm2, ingate 7,8,7 sectional area 264mm of gained ingate are calculated respectively by above-mentioned ratio2, ingate
8 sectional area 290mm2；Filling mould states and filling velocity are confirmed by simulation softward, when as a result showing that left and right sides product fills type and completes
Between quite, and the position flow velocity that dams is too fast, therefore the position cross-sectional dimension that dams is adjusted, and determines that the water inlet of each rising head cuts
Flow area 224mm2, final captured area 768mm2, with sprue ratio=0.95:1.
Resistance slag of the present utility model considers, main by simplified running gate system, arranges that vertical straight hole filter is completed.Should
With the resistance slag and steady flow result of filter, and by the setting of above-mentioned running gate system ratio, enable molten iron to be rapidly filled with die cavity, subtract
Few contact duration with air, reduces the generation of secondary slag.
The final product yield that this utility model is arranged in fact is calculated as follows：Foundry goods substance 2.35kg, holotype weight are 23.2, often
Type foundry goods gross weight is 2.35*6=14.1；Calculating yield rate is 14.1/23.2=60.7%, meets the expected requirements, and is far above
The product yield of general caliper, greatly reduces production cost, improve production efficiency.
The foundry goods of this utility model production, carries out the examination and test of products according to Customer Standard, counts percent defective≤3%.Its foundry goods
Presentation quality is good, carries out small quantities of hundred inspection and batch product sampling observation by X-ray, does not find shrinkage defect, follow-up machine is added and filled
After being followed up, feedback is good, and state without exception occurs, it is thus determined that excellent for technological feasibility.
