Abstract
The utility model provides an open stepped combined type gating system. The open stepped combined type gating system comprises a pouring cup and a downsprue connected to the pouring cup, wherein the downsprue is connected to the pouring cup and a cross gate which is connected to an ingate; the cross gate comprises at least two layers of cross gates, and each layer of cross gate is connected to the downsprue; the diameter of the pouring cup is in the range of 80mm-120mm, the diameter of cross section of the downsprue is in the range of 110mm-120mm, the diameter of cross section of the cross gate is in the range of 80mm-100mm, and the diameter of cross section of the ingate is in the range of 60mm-80mm; the bottom side of the downsprue is lengthened by 150mm. The open stepped combined type gating system has the advantages that the improved pouring system is easy to set and operate, the cost is not increased, the shortcomings such as cold shut, sand cut, water waves, sand burning and insufficient pouring are avoided, the rejection rate of castings is reduced to zero from original 15-20%, the repair rate is reduced to about 5-6% from original 55%, the production efficiency is greatly improved, and the production cost of castings is saved.
Description
Technical field
The utility model relates to casting moulding system, is specifically related to large-scale Shell-Class Gating System for Casting Steel.
Background technology
The running gate system of current large-scale Shell-Class steel-casting all adopts the mode of single level, many cast gates, runner gate is single level, the sectional area of ingate is down gate with the ratio of the area of down gate, runner gate: runner gate: ingate=1:1:1.2(ratio form is for approximate open), because the molten steel forming time is compared with long and produced multi-level cold shut, water wave and produce underpriming defect away from the local location of cast gate in the short transverse of foundry goods, the repair rate causing is therefrom up to more than 55%, and the percent defective of foundry goods reaches 15-20% left and right; Because ingate enters, flowing of die cavity molten steel is not steady and the time is longer, and has produced serious sand washing, scab defect.
Summary of the invention
For above-mentioned deficiency, in order effectively to solve the defects such as cold shut that large-scale Shell-Class steel-casting produces, water wave, sand washing, underpriming, the utility model provides a kind of opening, ladder combined type running gate system.
The utility model is achieved through the following technical solutions:
Opening, a ladder combined type running gate system, comprise cup and the sprue connecting with cup, and sprue connects cup and cross gate, and cross gate connects ingate.
Described cross gate consists of at least two-layer cross gate, and every layer of cross gate all connects with sprue.
Described cup diameter is 80mm～120mm, and sprue cross-sectional diameter is 110mm～120mm, and cross gate cross-sectional diameter is 80mm～100mm, and ingate cross-sectional diameter is 60mm～80mm.
Described sprue bottom side lengthens 150mm.
Useful technique effect of the present utility model: change new-type running gate system setting operation easy, do not exist cost to rise, generation without cold shut, water wave, sand washing, underpriming defect, its casting wasted product rate drops to zero by original 15-20%, repair rate drops to 5-6% left and right by original 55%, improve production efficiency, without waste product, produced, saved the production cost of foundry goods.
Accompanying drawing explanation
Fig. 1 is that siphon runner adds side and enters running channel schematic diagram.
Fig. 2 is that siphon runner adds side and enters running channel upward view.
Wherein: 1, cup, 2, sprue, 3, cross gate, 4, ingate, 5, ground floor cross gate, 6, second layer cross gate.
The specific embodiment
As shown in Figures 1 and 2, a kind of opening, ladder combined type running gate system, comprise cup 1 and the sprue 2 connecting with cup 1, and sprue 2 connects cup 1 and cross gate 3, and cross gate 3 connects ingate 4.
Described cross gate 3 consists of at least two-layer cross gate, and every layer of cross gate all connects with sprue 2.
Described cup diameter is 80mm～120mm, and sprue cross-sectional diameter is 110mm～120mm, and cross gate cross-sectional diameter is 80mm～100mm, and ingate cross-sectional diameter is 60mm～80mm.
Described sprue bottom side lengthens 150mm.
Embodiment 1: cup 1 cross-sectional diameter is 120mm, and sprue 2 cross-sectional diameters are 120mm, and bottom side lengthens 150mm, make molten steel from ladle, out have afterwards individual buffering nest, being unlikely to has large scouring force, makes the stability of molten steel better simultaneously, is unlikely to produce large whirlpool; Ground floor cross gate 5 and second layer cross gate 6 cross-sectional diameters are 100mm, the single cross-sectional diameter of ingate 4 is 80mm, from three, do not cause steel-casting to wash away the position little with thermal center and enter sand mold die cavity simultaneously, ground floor cross gate adopts the end to return formula running channel, guarantee that molten steel stable filling is filled to die cavity, does not produce large scouring force simultaneously; Second layer cross gate 6 can avoid ground floor running channel to wash away for a long time die cavity, causes the severe scab defect that produces of local scour, can guarantee again molten steel fast charging type to the greatest extent simultaneously, the quality that has guaranteed to cast firm part.
Embodiment 2: cup 1 cross-sectional diameter is 80mm, and sprue 2 cross-sectional diameters are 100mm, and bottom side lengthens 150mm, make molten steel from ladle, out have afterwards individual buffering nest, being unlikely to has large scouring force, makes the stability of molten steel better simultaneously, is unlikely to produce large whirlpool; Ground floor cross gate 5 and second layer cross gate 6 cross-sectional diameters are 80mm, the single cross-sectional diameter of ingate 4 is 60mm, from three, do not cause steel-casting to wash away the position little with thermal center and enter sand mold die cavity simultaneously, ground floor cross gate adopts the end to return formula running channel, guarantee that molten steel stable filling is filled to die cavity, does not produce large scouring force simultaneously; Second layer cross gate 6 can avoid ground floor running channel to wash away for a long time die cavity, causes the severe scab defect that produces of local scour, can guarantee again molten steel fast charging type to the greatest extent simultaneously, the quality that has guaranteed to cast firm part.
It is easy that the utility model changes new-type running gate system setting operation, do not exist cost to rise, generation without cold shut, water wave, scab, sand washing, underpriming defect, its casting wasted product rate drops to zero by original 15-20%, repair rate drops to 5-6% left and right by original 55%, improve production efficiency, without waste product, produced, saved the production cost of foundry goods.
