Abstract
The utility model discloses a pouring device of a top pouring type alloy casting, which consists of a copper mold (1), a pressing sleeve (2), stopping pieces (3), a cylinder-shaped sand core (4), a pouring bracket (5) and a cooling water channel (6). The copper mold (1) is arranged in the pouring bracket (5) and dipped in the cooling water channel (6); the pressing sleeve (2) is positioned above the pouring bracket (5); the cylinder-shaped sand core (4) is taken as a top casting head to be installed in the pressing sleeve (2); the bottom part of the cylinder-shaped sand core (4) is provided with a plurality of small holes with diameters of 3-8mm which are taken as inner pouring openings; the inner pouring openings are provided with the stopping pieces (3), wherein the stopping pieces (3) are made from copper alloy as the same as the casting, and the thickness of the stopping pieces is 0.8-3mm. By adopting the pouring device, the inner tissue of the casting is compact and even, thereby avoiding generating micro air holes and the like, preventing the casting from having dregs, and greatly improving the yield of the casting.
Description
Technical field
The present invention relates to and metal material casting equipment particularly a kind of apparatus for pouring of teeming formula alloy-steel casting.
Background technology
All casting methods of the castings production and other of alloy material are the same, if adopt traditional pouring procedure, if Design of Runner System is improper, the foundry goods inside of producing will produce slag inclusion or foundry goods dense internal organization degree varies causes, exists phenomenons such as miniature pore.
Summary of the invention
Purpose of the present invention is exactly at above problem, has designed one and has overlapped the apparatus for pouring that is used for alloy-steel casting, utilizes this covering device, solves the inner slag inclusion of foundry goods or dense structure's degree varies and causes, exists problems such as miniature pore.
Device of the present invention is by copper mold (1), gland (2), jam (3), the husky core (4) of tubular, cast support (5) and bosh (6) composition.Use copper alloy as mold materials, mainly be in order to guarantee foundry goods cooling fast in casting process, copper mold (1) places in the cast support (5), and be immersed among the bosh (6), use the outer wall of water quench mould during cast, to accelerate the cooling of foundry goods, the bottom formation temperature thermograde from high to low from the cast gate top to foundry goods helps foundry goods and realizes consecutive solidification simultaneously.Gland (2) is positioned at cast support (5) top; the husky core of tubular (4) is contained in the inside of gland (2) as the top dead head; husky core (4) of tubular and gland (2) are cone; the male-tapered of the husky core of the inner conical of gland (2) and tubular (4) cooperates and pushes down tubular sand core (4); gland (2) can play effect fixing and protection to the husky core of tubular (4), avoids the husky core of tubular (4) to be collided and damages.Husky core (4) of tubular and gland (2) form an integral installation on the top of copper mold (1), help the insulation after metal liquid is poured into a mould and the demoulding of foundry goods like this.The bottom of the husky core of tubular (4) offers the aperture of a plurality of diameter 3～8mm as ingate, foundry goods produces slag inclusion in order to prevent to pour into a mould, on the ingate of the husky core of tubular (4) bottom, jam (3) is installed, what this jam (3) adopted is to make with the foundry goods identical materials, the shape of jam (3) can be square, circular and other various suitable thin plate sheets, and the thickness of jam (3) is generally 0.8～3mm.
During cast, alloy liquid is poured in the chiltern rising head of top, because stopping of jam (3), alloy liquid in the chiltern rising head can not enter in the lower mold cavity via ingate immediately, when jam (3) is subjected to the heat effect of alloy liquid and fusing when losing barrier effect gradually, alloy liquid in the chiltern rising head has had certain degree of depth, and at this moment the slag in the metal liquid is owing to proportion gently floats, and the clean metal liquid in chiltern rising head bottom enters die cavity by ingate.The degree of depth of alloy liquid is under the prerequisite of above position, middle part in keeping rising head, continues cast until watering completely whole die cavity.
Adopt apparatus for pouring of the present invention, when the cast alloy-steel casting, because alloy liquid pours into earlier in the chiltern rising head from the top, enter in the shaping mold cavity of bottom via ingate then, under the effect of cooling water, the cooling of foundry goods has succession, the bottom formation temperature thermograde from high to low from the cast gate top to foundry goods, help foundry goods and realize consecutive solidification, guarantee that the dense internal organization of foundry goods is even.In order to prevent that foundry goods from producing defectives such as slag inclusion, pore, place jam on ingate top, make alloy liquid enter time retardation in the copper mold chamber, the discharge of in the chiltern rising head, floating of slag in the metal liquid, thereby prevent that these slags from entering die cavity, avoided the generation of slag inclusion in the foundry goods, the qualification rate of foundry goods is significantly improved.

The specific embodiment
Embodiment 1:
Present embodiment is an example with the cast copper-alloy casting, and the structure and the concrete pouring procedure of the apparatus for pouring of teeming formula alloy-steel casting of the present invention is described.
Fig. 1 is the apparatus for pouring structural representation of teeming formula alloy-steel casting of the present invention, and the apparatus for pouring of teeming formula alloy-steel casting is by copper mold (1), gland (2), jam (3), the husky core (4) of tubular, cast support (5) and bosh (6) composition.Copper mold (1) places in the cast support (5), and is immersed among the bosh (6), and the temperature of cooling water is controlled between 0～40 ℃; Tubular core (4) is contained in the gland (2) as the top dead head, the assembly of the husky core of gland (2) and tubular (4) is installed on the copper mold (1), the bottom of the husky core of tubular (4) has the aperture of a plurality of diameter 5mm as ingate, foundry goods produces slag inclusion in order to prevent to pour into a mould, on ingate, be placed with jam (3), what this jam (3) adopted is that the Cu alloy material identical with foundry goods made, and jam (3) is shaped as circle, and the thickness of jam is 1mm.
During cast, copper alloy liquid is poured in the chiltern rising head of top, because stopping of jam (3), copper alloy liquid in the chiltern rising head can not enter in the lower mold cavity via ingate immediately, when jam (3) is subjected to the heat effect of copper alloy liquid and fusing when losing barrier effect gradually, copper alloy liquid in the chiltern rising head has had certain degree of depth, at this moment the slag in the copper alloy liquid is owing to proportion gently floats, and the clean copper alloy liquid in chiltern rising head bottom enters die cavity by ingate.The degree of depth of copper alloy liquid is under the prerequisite of above position, middle part in keeping rising head, continues cast until watering completely whole die cavity.
