Description
Technical field
The utility model relates to casting technology field, particularly a kind of blast pipe casting pattern aspect technology.
Background technology
Blast pipe is the parts of automobile engine key, and now, most blast pipe all adopts sand casting, but the qualified casting of blast pipe is all the time all on the low side, reason has a lot, main is that a lot of factories are used greensand casting techniques, but this technique gas permeability be on duty mutually, make the qualified casting of blast pipe low; Next is in the time of technological design, and core is all wrapped in housings mostly, and because precoated sand is in the situation that being subject to high temperature, resin burning can produce gas.If gas can not be discharged the outside of foundry goods in time, can on foundry goods, produce bubble, cause high temperature core gas in the time of casting can not arrange, make the place of product boss, there is a large amount of bubbles, cause the phenomenons such as product peeling, wrinkling, fleshiness and shrinkage cavity, also make finished product rate greatly reduce.
For above-mentioned technological deficiency, need a kind of blast pipe casting sand core of invention gas extraction system that leaks outside badly and improve blast pipe yield rate.
Summary of the invention
The utility model causes in order to overcome blast pipe cast article peeling in prior art, wrinkling, fleshiness etc. the problem that yield rate is low, invents a kind of blast pipe casting pattern, makes to cast gained blast pipe and has the advantages that quality is good, yield rate is high.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of blast pipe casting pattern, comprising:
Blast pipe core, and with the supporting blast pipe sand mold of blast pipe core; Between described blast pipe core and described blast pipe sand mold, be formed for the cavity of casting, wherein, described blast pipe core is hollow structure, described hollow structure extends to outside several exhaust outlets that form, described several exhaust ports are provided with horizontal the taking for tackling molten iron outflow, and described several exhaust outlets extend to outside horizontal taking through horizontal taking.
Preferably, this blast pipe casting pattern also comprises an evagination core print, is located at described blast pipe core top.
Preferably, between described evagination core print and described blast pipe core, formation is greater than 110 ° and is less than the angle of 180 °.
Preferably, described evagination core print is hollow structure, and the hollow structure of described evagination core print is communicated with the hollow structure of described blast pipe core, and described evagination core print end is provided with the opening being communicated with hollow structure.
By above-mentioned technical scheme, the beneficial effects of the utility model are as follows:
The utility model blast pipe casting pattern, the hollow structure of blast pipe core and exhaust pipe mouth extend to the horizontal outer interruption-forming air guide channel that goes out of taking, the gas producing in air in blast pipe sand mold chamber and blast pipe core when high temperature in casting process can be discharged, eliminate the phenomenon of the exhaust pipe shaft foaming that forms, peeling, wrinkling and shrinkage cavity, greatly improved the qualified casting of blast pipe; Meanwhile, the evagination core print that the utility model blast pipe core top end arranges plays the effect of location in casting blast pipe process, makes blast pipe in casting process, be not easy skew, and the product quality forming is good; Further, the casting method that the utility model adopts, makes that product when casting productive rate is high, dimensionally stable, and gas forming amount is few; Meanwhile, the utility model production gained blast pipe not only yield rate has improved, and quality also rises thereupon, thereby defect ware is reduced, and has improved production efficiency, has reduced production cost.

Detailed description of the invention
Further describe the utility model referring to detailed description of the invention, to make those skilled in the art can implement according to this with reference to description word, originally make utility model protection scope not be limited by embodiment of the present utility model.
Embodiment 1
See also Fig. 1 to Fig. 6, it is respectively blast pipe core front view of the present utility model, the utility model blast pipe core side view, the utility model upper casing dorsal view, the utility model upper casing front view, the utility model lower casing front view, the utility model lower casing+blast pipe core.
As shown in Figure 7, a kind of blast pipe casting pattern, comprises blast pipe core 1, and blast pipe sand mold 2, and blast pipe core 1 adopts precoated sand method casting core, and blast pipe sand mold 2 adopts core shooting technique to make; The cavity that is formed for casting between blast pipe core 1 and blast pipe sand mold 2, blast pipe sand mold 2 comprises upper casing 7 and upper casing 8, and upper casing 7 lower backside middle parts are provided with blasthole 4, and in the positive chamber of upper casing 7, the place corresponding with blasthole is provided with groove.
Blast pipe core 1 surrounds a sector structure by the arm of 4 hollow structures, the arm of 4 hollows intersects at blast pipe core 1 top, evagination core print 3 is more up located to be provided with in blast pipe core 1 top rear face, arm intersection, evagination core print 3 forms 110 ° of angles with blast pipe core 1 top rear face, the arm of 4 hollows extends to outside 4 exhaust outlets 5 that form, exhaust outlet 5 places are provided with for tackling the horizontal of molten iron outflow and take 6, and exhaust outlet 5 is taken 6 and extended to outside horizontal taking through horizontal; The positive top rail of blast pipe core 1 is taken 6 the partial occlusion of 4 arms is lived, and blast pipe core 1 back side is horizontal takes 6 and will not shelter from the front corresponding arm of part that is blocked; Blast pipe core 1 is put into lower casing 8 inner chambers, and evagination core print 3 embeds in embedding mouth 9, blast pipe core 1 is placed reliable, then covers upper casing 7, and now the positive chamber of upper casing 7 inner groovy just and the horizontal cavity forming of taking between 6; After button is steady, being fixed on special cast chest the inside buries, melted molten iron flows into from blasthole 4, through upper casing 7 positive chamber inner groovy and the horizontal cavity forming between 6 of taking, flow into the casting cavity of blast pipe sand mold 2 and blast pipe core 1, then fill up casting cavity; Now, the molten iron of high temperature contacts with blast pipe core 1, make blast pipe core 1 produce gas, most gas is under the pressure of molten iron, can be discharged to outside blast pipe sand mold 2 by extending to the horizontal exhaust outlet of taking 6 from the structure of blast pipe core 1 hollow, thereby the gas producing is discharged outside product in time, in molten iron, just can not make product rejection because of there being bubble can not arrange like this.
