Description
Technical field
The utility model belongs to casting mould technical field, is specifically related to a kind of high-nickel austenite nodular cast iron blast pipe casting die.
Technical background
high-nickel austenite nodular cast iron is because possessing good heat resistance and corrosion resistance, increasing application is obtained in reality, but because high-nickel austenite nodular cast iron mushy freezing mode causes shrinkage tendency very large, make feeding difficulty, have in process of production use larger rising head to carry out feeding to thermal center region, thus causing product yield to reduce, the difficulty of deburring increases, and production cost increases, and the conventional strong feeding technology of rising head, because of casting structure restriction, often need additionally to increase core, facilitate casting, such raw material, the electricity charge, the artificial production cost that waits just adds, a kind of wide conformal blank riser system of risers is disclosed in CN 202683954 U, belong to foundry engieering, it comprises die cavity, blank riser, die cavity, blank riser overlaps to form the flanging passage of both connections in vertical part, first limit of flanging passage is the edge of the corresponding blank riser of die cavity, the Second Edge of flanging passage is the edge of the corresponding die cavity of blank riser, Second Edge is identical with the shape on the first limit, the both sides of flanging passage equidistantly make flanging passage wide.Though its its arrived good effect not to high-nickel austenite nodular cast iron provider to, and also not yet occur in other documents the method that addresses this is that therefore needing a kind of casting die that can improve high-nickel austenite nodular cast iron blast pipe product yield.
Utility model content
Main purpose of the present utility model is to provide a kind of simple and practical, effectively can prevent Shrinkage cavity and improve the casting die of product yield.
In order to the technical solution of the utility model that solves the problem: a kind of high-nickel austenite nodular cast iron blast pipe casting die, comprise type cavity mould, described type cavity mould comprises four inlet flanges and a flange of giving vent to anger, described inlet flange connects dead head, described dead head is connected with ingate, described ingate is connected with cross gate, and described cross gate arranges vertical running channel, described in flange of giving vent to anger conformal blank riser is set.
The quantity of described conformal blank riser is one.
Described flange of giving vent to anger is connected with conformal blank riser by cuboid running channel.
The utility model adopts conformal blank riser to be connected with cuboid running channel with flange face seamed edge of giving vent to anger, rising head is made to leave flange face thermal center, avoid and directly to contact with flange face thus the cooling caused is slow, cause Shrinkage cavity phenomenon, and owing to making riser neck short by the mode of cuboid running channel connection conformal blank riser, thin, wide, feeding capacity by force and easily remove, not only save the product yield that material improves foundry goods, the dead head simultaneously adopted is feeding head, and all adopt the mode keeping certain gap with flange face, make it that thermal center can be avoided to assemble, accelerate cooling velocity, also make easily to be taken off when cleaning out burr simultaneously, this set method decreases the shaping core that give vent to anger flange and inlet flange riser neck make, make it can reduce the use amount of molten metal, improve product yield.
In the utility model give vent to anger flange volume and area all very large, it is made easily to form casting thermal center, thus cause cooling slowly, therefore a very large feeding head is often set thereon, Shrinkage cavity is prevented with this, but its effect is general and can produce a huge rising head, product yield is caused to decline, cause the very large wasting of resources and loaded down with trivial details later stage cleaning process, and when blast pipe is made for high-nickel austenite nodular cast iron, mushy freezing mode due to material makes Shrinkage cavity very serious, and the utility model well solves these problems, original product yield is made to be increased to present 50% by 40%, drastically increase metal utilization rate, be worthy to be popularized and application.

Detailed description of the invention
Embodiment one: a kind of high-nickel austenite nodular cast iron blast pipe casting die, comprise type cavity mould 9, described type cavity mould 9 comprises four inlet flanges 7 and a flange 6 of giving vent to anger, described inlet flange 7 connects dead head 4, described dead head 4 is connected with ingate 3, described ingate 3 is connected with cross gate 2, and described cross gate 2 arranges vertical running channel 1, described in flange 6 place of giving vent to anger conformal blank riser 5 is set.
The quantity of described conformal blank riser 5 is one.
Described flange 6 of giving vent to anger is connected with conformal blank riser 5 by cuboid running channel 8.
Embodiment two: a kind of high-nickel austenite nodular cast iron blast pipe casting die, comprise type cavity mould 9, described type cavity mould 9 comprises four inlet flanges 7 and a flange 6 of giving vent to anger, described inlet flange 7 connects dead head 4, described dead head 4 is connected with ingate 3, described ingate 3 is connected with cross gate 2, and described cross gate 2 arranges vertical running channel 1, described in flange 6 place of giving vent to anger conformal blank riser 5 is set.
Described flange 6 of giving vent to anger is connected with conformal blank riser 5 by cuboid running channel 8.
Embodiment three: a kind of high-nickel austenite nodular cast iron blast pipe casting die, comprise type cavity mould 9, described type cavity mould 9 comprises four inlet flanges 7 and a flange 6 of giving vent to anger, described inlet flange 7 connects dead head 4, described dead head 4 is connected with ingate 3, described ingate 3 is connected with cross gate 2, and described cross gate 2 arranges vertical running channel 1, described in flange 6 place of giving vent to anger conformal blank riser 5 is set.
The utility model adopts conformal blank riser to be connected with cuboid running channel with flange face seamed edge of giving vent to anger, rising head is made to leave flange face thermal center, avoid and directly to contact with flange face thus the cooling caused is slow, cause Shrinkage cavity phenomenon, and owing to making riser neck short by the mode of cuboid running channel connection conformal blank riser, thin, wide, feeding capacity by force and easily remove, not only save the product yield that material improves foundry goods, the dead head simultaneously adopted is feeding head, and all adopt the mode keeping certain gap with flange face, make it that thermal center can be avoided to assemble, accelerate cooling velocity, also make easily to be taken off when cleaning out burr simultaneously, this set method decreases the shaping core that give vent to anger flange and inlet flange riser neck make, make it can reduce the use amount of molten metal, improve product yield.
