Abstract

The invention discloses a kind of metal type dies, it comprises mold and bed die, mold is provided with the taper type sprue gate, on mold and bed die the sprue gate around be provided with several die cavities, on the land area of mold and bed die, be respectively equipped with the running channel that is communicated with die cavity and sprue gate, on the land area of mold and bed die, be respectively equipped with the alignment pin of projection and recessed locating hole; On described mold land area, be respectively equipped with the outlet passageway that leads to mold outer surface from the side of each running channel.A kind of metal type dies of the present invention is to be provided with the outlet passageway that leads to mold outer surface from the running channel of mould on the mold land area, gas in the mold cavity is discharged smoothly, having prevented has influenced the quality of foundry goods because of containing a large amount of bubbles in the foundry goods, is particluarly suitable for using on the continuous casting product line.

Description

A kind of metal type dies

(1) technical field:

The present invention relates to a kind of mould, be specifically related to a kind of metal type dies.

(2) background technology:

Mould is the visual plant in the foundry industry, the quality of mould directly has influence on the quality of foundry goods, existing mould is except casting gate, the die cavity of mould is generally the space of a relative closure, gas when causing casting of metals liquid to enter die cavity in the die cavity can't be discharged, caused and contained a large amount of bubbles in the foundry goods, influenced the quality of foundry goods.At present, in Casting Equipment, there is the centrifugation method taked to remove bubble in the foundry goods, but because the die cavity of mould still is the space of a relative closure, the outer surface of foundry goods has just been arrived in the gas in the casting of metals liquid in centrifugation, though air entrapment has reduced, but cast outer surface is uneven, has influenced the quality of foundry goods too.

(3) summary of the invention:

The object of the present invention is to provide a kind of metal type dies that can discharge gas in the casting of metals liquid smoothly, improve casting quality.

For achieving the above object, a kind of metal type dies of the present invention comprises mold and bed die, mold is provided with the taper type sprue gate, on mold and bed die the sprue gate around be provided with several die cavities, on the land area of mold and bed die, be respectively equipped with the running channel that is communicated with die cavity and sprue gate, on the land area of mold and bed die, be respectively equipped with the alignment pin of projection and recessed locating hole; On described mold land area, be respectively equipped with the outlet passageway that leads to mold outer surface from the side of each running channel.

On the close position of running channel of each die cavity, be provided with the passage of giving vent to anger that props up that leads to corresponding outlet passageway from die cavity.

Owing to taked technique scheme, a kind of metal type dies of the present invention is to be provided with the outlet passageway that leads to mold outer surface from mold cavity and running channel on the land area of mold, the cavity that can make mould mainly is that the gas in the die cavity 4 is discharged smoothly, prevented that foundry goods from having influenced the quality of foundry goods because of containing a large amount of bubbles, even when taking spun casting, as long as make the position of connector in the outlet passageway opposite with the direction that casting of metals liquid flows when running channel enters die cavity, can guarantee the gas in the die cavity 4 to be discharged smoothly and casting of metals liquid is thrown out of, on continuous casting product line, use the back effect fairly obvious, improved the quality of foundry goods greatly.

(4) description of drawings:

Fig. 1 is the internal structure schematic diagram of a kind of metal type dies of the present invention;

Fig. 2 is the internal structure schematic diagram of mold in a kind of metal type dies shown in Figure 1;

Fig. 3 is the internal structure schematic diagram of bed die in a kind of metal type dies shown in Figure 1.

(5) specific embodiment:

The present invention is further detailed explanation below in conjunction with accompanying drawing.

By Fig. 1, Fig. 2 as seen, a kind of metal type dies of the present invention comprises mold 1 and bed die 2, mold 1 is provided with taper type sprue gate 3, on mold 1 and bed die 2 sprue gate 3 around be provided with several die cavities 4, die cavity 4 is the position of mould medium casting, be respectively equipped with the running channel 5 that is communicated with die cavity 4 and sprue gate 3 on the land area of mold 1 and bed die 2, casting of metals liquid 3 enters the die cavity 4 that enters mould by running channel 5 from the sprue gate; On the land area of mold 1 and bed die 2, be respectively equipped with the alignment pin 6 of projection and recessed locating hole 7, mold 1 and bed die 2 can not misplaced when matched moulds; On described mold 1 land area, be respectively equipped with the outlet passageway 8 that leads to mold outer surface from the side of each running channel 5, the cavity that can discharge mould mainly is the gas in the die cavity 4, outlet passageway 8 can be designed to straight line as required or the curve of certain radian is arranged, for spun casting, generally be designed to the curve consistent with centrifugal direction of rotation.Gas in the further emptying die cavity 4 reduces the decline that causes casting quality because of the existence of gas in the die cavity 4, is provided with the passage 9 of giving vent to anger that props up that leads to corresponding outlet passageway 8 from die cavity 4 on each die cavity 4 close position of running channel 5.The interior connector of outlet passageway 8 is located on the side of running channel 5, and the venthole of outlet passageway 8 is located at the outer surface of mold 1; The interior connector that props up the passage 9 of giving vent to anger is located at die cavity 4 near on the positions of running channel 5, props up the passage 9 of giving vent to anger and communicates with outlet passageway 8 nearby; The every group of outlet passageway 8 and the passage 9 of giving vent to anger constitute irregular " Y " shape on the land area of mold 1, like this, just constituted an outlet passageway that complete running channel 5 and die cavity 4 by mould leads to mold outer surface, the gas in the mold cavity 4 is discharged smoothly.Outlet passageway 8 need be set according to the size of mould and die cavity 4 with the size of propping up passage 9 apertures of giving vent to anger, and general aperture is less, can discharge air and get final product, and outlet passageway 8 can be semicircle, triangle or trapezoidal with the section that props up the passage 9 of giving vent to anger.

When taking spun casting, because outlet passageway 8 is located at respectively on the side and the die cavity 4 close positions of running channel 5 of running channel 5 with the interior connector that props up the passage 9 of giving vent to anger, as long as make the position of outlet passageway 8 and the interior connector that props up the passage 9 of giving vent to anger opposite with the direction that casting of metals liquid flows when running channel 5 enters die cavity 4, just can utilize casting of metals liquid mainly is that gas in the die cavity 4 is driven out of outside the mould from the outlet passageway 8 and the passage 9 of giving vent to anger with the cavity of mould, simultaneously casting of metals liquid enters behind the die cavity 4 cooling curing gradually, both can guarantee that the gas in the mold cavity 4 discharged and don't make casting of metals liquid to be thrown out of smoothly, on continuous casting product line, use the back effect fairly obvious, having prevented has influenced the quality of foundry goods because of containing a large amount of bubbles in the foundry goods, has improved the quality of foundry goods greatly.Be particluarly suitable for using on the continuous casting product line.
