Abstract
The utility model discloses a sand mould structure for a brake caliper shell, which comprises a sand mould main body, wherein six cavities are arranged in the sand mould main body; mud cores are arranged in the cavities; two big risers and two small risers are arranged on the sand mould main body; each of the big risers is respectively communicated with two cavities through riser necks; and each of the small risers is communicated with one cavity through the riser neck. According to the sand mould structure for the brake caliper shell, big and small risers are arranged on the sand mould main body and each of the big risers is simultaneously connected with two cavities, so that the quantity of the risers is effectively reduced under the condition of increasing the quantity of the cavities, the volume of the sand mould main body is reduced and the purpose of increasing the craft yield of products and the capacity is achieved.
Description
Technical field
The utility model relates to casting field, particularly a kind of sand mold structure that is used for automobile brake pincers shell cast.
Background technology
Caliper shell is the product of a hardware and software platform, can be applicable in many moneys vehicle, and this part is always from external import before, and in order to reduce production costs, this part has begun to domesticize at present.Along with pushing forward comprehensively of auto parts production domesticization, this product demand amount is increased sharply (present 180,000/month, preparatory 12 years is more than 200,000/month), and so big output requires to make the production capacity of manufacturing enterprise be faced with stern challenge.Traditional handicraft like product yield rate is about 45% at present, percent defective about 6%.In order to satisfy client's demand; Promote the production capacity of product, method commonly used is exactly the quantity that increases die cavity in the sand mold, and along with the increase of die cavity quantity; The quantity of rising head also can correspondingly increase; So just need the sand mold body that bigger volume is arranged, the volume of sand mold body then can make the product yield of product reduce greatly, increases the production cost of enterprise.
The utility model content
To the deficiency of above-mentioned prior art, the purpose of the utility model provides a kind of sand mold structure that is used for the caliper shell casting of rising head negligible amounts.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of sand mold structure of caliper shell; Comprise the sand mold body; Be provided with six die cavities in the said sand mold body, be provided with the loam core in the said die cavity, also be provided with two big rising heads and two little rising heads on the said sand mold body; Said big rising head is communicated with two die cavities respectively through riser neck, and said little rising head is communicated with a die cavity through riser neck.
Preferably, the volume of said big rising head is 340cm
3, the modulus of big rising head is 13mm.
Preferably, the volume of said little rising head is 125cm
3, little feeder modulus: 10mm.
Preferably, the modulus of said riser neck is 3mm.
Preferably, said big rising head, little rising head are positioned on the running channel of said sand mold body.
Technique scheme has following beneficial effect: the sand mold structure of this caliper shell is provided with large and small two kinds of different rising heads on the sand mold body; Each big rising head is connected with two die cavities simultaneously; So just can under the prerequisite that increases the die cavity number, effectively reduce the quantity of rising head; Thereby reduce the volume of sand mold body, and then reach the raising production capacity, the purpose of the rate of reducing the number of rejects and seconds.
Above-mentioned explanation only is the general introduction of the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, below this patent is elaborated with the preferred embodiment and the conjunction with figs. of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1; The sand mold structure of this caliper shell comprises sand mold body 1, in sand mold body 1, is provided with six die cavities 4,5,6,7,8,9, and each die cavity all is communicated with the cast gate 2 of sand mold body 1 through running channel 3; Be equipped with loam core 10 in each die cavity; The non-foundry goods face in loam core 10 can all be removed, and with the size and the weight in minimizing loam core, and then reduces gas forming amount.
The running channel of sand mold body 1 is provided with 11,12 and two little rising heads 13,14 of two big rising heads; Big rising head 11 is communicated with die cavity 4,5 respectively through riser neck; Big rising head 12 is communicated with die cavity 7,8 respectively through riser neck; Little rising head 13 is communicated with die cavity 6 through riser neck, and little rising head 14 is communicated with die cavity through riser neck.The volume of big rising head 11,12 is 340cm
3, modulus is 13mm (modulus=volume/surface area).The volume of little rising head 13,14 is 125cm
3, modulus: 10mm.The riser neck modulus of above-mentioned each rising head is 3mm.Choked flow sectional area according to calculating each foundry goods is: F=90mm
2, for preventing that sand washing and each foundry goods of riser feeding effect from advancing the iron sectional area and can be set in 90-100mm
2, the sectional area of the running channel that communicates with each die cavity can advance the iron sectional area according to above-mentioned foundry goods and suitably adjust.
But 6 foundry goods of one-shot forming when using sand mold structure cast caliper shell foundry goods, the product yield of product will bring up to 67% from original 45%, improve nearly 1.4 times of production efficiency.And, use and to make the casting material stable performance because the rising head number has only 4, and the volume of sand mold body is less; Internal soundness (shrinkage porosite situation) is solved; The percent defective of product is obviously descended, can make foundry goods criticize the minimizing of seam simultaneously, can reduce foundry goods polishing workload; Improve the polishing operation environment, reduce production costs.Use this sand mold structure production cost to reduce to 23.925 yuan present/part from 26.153 yuan original/part according to statistics, cost per unit can descend 2.228 yuan.
More than the sand mold structure of a kind of caliper shell that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
