Abstract
The invention discloses a low pressure casting mould which comprises a crucible, a riser tube, an air inlet tube, a sealing cover, a pouring gate, a cavity and a cast. The cavity is arranged in the cast, the pouring gate is arranged on one side of the cavity, the riser tube is arranged in the crucible, the sealing cover is arranged between the cast and the crucible, and the air inlet tube is arranged between the sealing cover and the crucible. Mold filling is conducted through molten metal under the effect of pressure, so that mold filling capability is improved, casting with a clear outline can be obtained, and the yield is high. By means of the mould, the molten metal is stable in mold filling in the mold filling process, is solidified under the effect of pressure and is completely fed, so that the casting is compact in texture and high in dynamic performance. The tensile strength and the hardness are improved by about 10% compared with a traditional gravity casting mould.
Description
Technical field
The present invention relates to a kind of low pressure casting die.
Background technology
Low pressure casting has the stock utilization height, the advantages such as soup automation are annotated in realization easily, centered by automobile component, progressively established the firm status of the main casting of light alloy casting, but existing low pressure casting die make easily liquid metal filling steadily and mold-filling capacity not high.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, it is steady that the present invention proposes a kind of liquid metal filling, and mold-filling capacity is good, the low pressure casting die that feeding is abundant, yield rate is high.
Technical scheme: for solving the problems of the technologies described above, the present invention proposes a kind of low pressure casting die, it comprises: crucible, stalk, air inlet pipe, seal cover, running channel, die cavity and casting mold, be provided with die cavity in the described casting mold, a side of die cavity is provided with running channel, is provided with stalk in the described crucible, the place is provided with seal cover in the middle of described casting mold and the crucible, and the place is provided with air inlet pipe in the middle of seal cover and the crucible.
Described stalk, die cavity and casting mold link to each other successively.
Be provided with molten metal in the described crucible.
Beneficial effect: a kind of low pressure casting die of the present invention, by utilizing the driving force of filling casting mold, make molten metal along flowing with the gravity rightabout, after the molten metal cooling in entering die cavity, not solidified molten metal falls back in the crucible, compare with traditional casting mould, saved cost, it is steady that this mould makes molten metal fill type in cavity filling process, because molten metal is effect lower charging type at pressure, therefore, mold-filling capacity improves, be conducive to obtain the foundry goods of clear-cut, and yield rate is high, because molten metal is to solidify under the effect of pressure, feeding is abundant, so the dense structure of foundry goods, mechanical property is high, and tensile strength is compared with traditional gravity casting die with hardness and improved about 10%.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of low pressure casting die of the present invention comprises: crucible 1, stalk 2, air inlet pipe 3, seal cover 4, running channel 5, die cavity 6 and casting mold 7.
Be provided with die cavity 6 in the described casting mold 7, a side of die cavity 6 is provided with running channel 5, is provided with stalk 2 in the described crucible 1, and the place is provided with seal cover 4 in the middle of described casting mold 7 and the crucible 1, and the place is provided with air inlet pipe 3 in the middle of seal cover 4 and the crucible 1.
Described stalk 2, die cavity 6 and casting mold 7 link to each other successively.
Be provided with molten metal 8 in the described crucible 1.
The compressed air of drying is passed in the airtight container crucible 1 that molten metal 8 is housed, act on molten metal 8 liquid levels that keep constant temperature, make molten metal 8 enter die cavity 6 through running channel 5 from bottom to up along stalk 2, after band molten metal 8 is full of die cavity 6, increase air pressure, make molten metal 8 solidification forming under the effect of pressure in the die cavity 6, then remove the gas pressure on the liquid level, make that not solidified molten metal 8 falls back in the crucible 1 in the stalk 2, open again casting mold, take out foundry goods.
This low pressure casting die is by utilizing the driving force of filling casting mold, make molten metal along flowing with the gravity rightabout, after the molten metal cooling in entering die cavity, not solidified molten metal falls back in the crucible, compare with traditional casting mould, saved cost, it is steady that this mould makes molten metal fill type in cavity filling process, because molten metal is effect lower charging type at pressure, therefore, mold-filling capacity improves, and is conducive to obtain the foundry goods of clear-cut, and yield rate is high, because molten metal is to solidify under the effect of pressure, feeding is abundant, so the dense structure of foundry goods, mechanical property is high, and tensile strength is compared with traditional gravity casting die with hardness and improved about 10%.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalents that Spirit Essence is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
