Abstract
The utility model discloses a special moulding flask for exhausting gas and preventing metal breakout, which comprises an upper moulding flask, a lower moulding flask and a core bar of a sand core inthe middle part. Two sides of the upper moulding flask (10) and the lower moulding flask (20) are respectively provided with a circular-arc gap for a die core point; an arc flange (11) of the upper moulding flask and an arc flange (21) of the lower moulding flask are arranged on the gap; the middle of the sand core (30) is provided with a hollow exhausting core bar (32), the circumferential wall of which is provided with an exhausting hole (322), and two ends of the hollow exhausting core bar (32) are respectively provided with a support strip (321); and the sand core (30) is provided with a slope structure at the core points at two ends. When die compounding and sand filling are conducted, the special moulding flask can effectively prevent the breakout of molten iron and improve the gas exhausting of the sand core at the important part of a cast; when casting is conducted, gases produced in the sand core can be exhausted from two ends by holes on the periphery of the core bar in the middle part so as to prevent the cast from generating air hole defect, thereby ensuring the reliability of the overall quality of the cast.
Description
Technical field
The utility model relates to a kind of foundry sand case, especially a kind of exhaust and anti-special shape mo(u)lding box of metalling run out that is used for bearing block class foundry goods.
Background technology
A lot of equipment parts all adopt foundry goods, and the scope of application of foundry goods is very wide, and general foundry goods all is the frame mode by the sandbox casting; For the bearing block foundry goods, the middle part through hole is the key position that bears pressure, this position casting quality is strict, the exhaust of sand mold and core becomes important technology controlling and process structure, the sandbox that this type of bearing block foundry goods is commonly used is not taken into account the effective exhaust of exhaust of sand mold and core, cause foundry goods to occur pore, defective such as loose easily, thereby reduce whole casting quality.
The utility model content
The utility model fails to resolve sand mold for the existing bearing block class foundry goods class sandbox of solution and the core exhaust is asked
Topic causes the foundry goods total quality not high enough, occur easily in the casting cycle molten iron metal run out present situation such as phenomenon and provide a kind ofly can effectively realize the exhaust of sand mold and prevent the exhaust that molten iron is run out of and prevent metalling run out special shape mo(u)lding box.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: a kind of exhaust and the anti-special shape mo(u)lding box of metalling run out, the arbor that comprises upper and lower sandbox and middle core, described cope and drag box both sides are provided with circular arc cutaway to mold core head position, indentation, there is provided with cope arc flange and drag box arc flange, described core is provided with hollow exhaust arbor at mid portion, place, on the circumferential wall of hollow exhaust arbor and two ends is provided with steam vent, and core is beginning to shrink to the two ends core print respectively to become the gradient structure with hypotenuse by core print place, two ends.The gas that produces in the core is discharged from two ends by the hole on the middle arbor circumference, avoids foundry goods to produce gas hole defect, thereby has guaranteed casting quality; Back-up sand the time, molten iron was run out of when preventing to pour into a mould when the ramp structure of the intersection of core core print and external mold core print was convenient to matched moulds.
As preferably, the tank wall body of described cope and drag box is provided with steam vent.Conveniently be beneficial to the exhaust of sand mo(u)ld.
As preferably, the top of described cope and drag box bottom are provided with reinforcement, improve sandbox intensity.
The beneficial effects of the utility model are: be convenient to back-up sand when matched moulds, prevent that effectively the cast situation of metalling run out from taking place, the gas that produces in the core during cast is discharged from two ends by the hole on the middle arbor circumference, improved the exhaust of foundry goods significant points sand core, avoid foundry goods to produce defectives such as pore, thereby guaranteed the quality of foundry goods significant points.

The specific embodiment
Fig. 1, among the embodiment shown in Figure 3, a kind of exhaust and the anti-special shape mo(u)lding box of metalling run out, comprise, the arbor of drag box and middle core, described cope 10 is provided with circular arc cutaway with drag box 20 both sides to core rod head position, indentation, there is provided with cope arc flange 11 and drag box arc flange 21, described core 30 is provided with hollow exhaust arbor 32 at mid portion, the circumferential wall of hollow exhaust arbor 32 is provided with steam vent 322, the place, two ends of exhaust arbor 32 is provided with support bar 321, and core 30 is beginning to shrink to the two ends core print respectively to become the gradient structure with core print hypotenuse 311 by core print place, two ends.The tank wall body of described cope 10, drag box 20 is provided with steam vent 40.The top of described cope and drag box bottom are provided with reinforcement 22.
In the use, earlier with core 30 times at the counterdie die cavity, the top box that closes then locking, the two ends core print has buried sand at the flange place, molten iron is run out of when preventing to pour into a mould; The gas that produces in the core during cast is discharged by the steam vent on the arbor circumference 322, and discharges by the space between the arbor two end supports bar; Gas during 50 li cast of foundry goods is discharged from rising head 70.
