Abstract
The utility model relates to a cast large -scale complicated steel -casting the gating system, the tapping mouth of a river of toper pouring basin brick and sprue butt joint, the sprue lower extreme is passed a bridge through the centre and ji zhaquan is connected, and jizhaquan connects the cross gate circle, and the cross gate waters in circling end equipartition several to be watered the upper end in, and is connected with the product stator, sets up the rising head that multiple model is carried out the feeding, is given vent to anger on the product stator. The sprue: the cross gate circle: the interior sectional area that waters compares for = 1: 1.4: 6.9. During the use, toper pouring basin brick highly be higher than product die cavity height, during toper pouring basin brick was poured into a mould to the molten steel, when the molten steel arrived 12 riser heights, point towards rising head, molten steel filled up the rising head, the molten steel slag trap circle of flowing through, the oxidizing slag is kept off in the upper end, pure molten steel waters the leading -in stator die cavity of reposition of redundant personnel in, through the cross gate circle. The utility model has the advantages of being simple in structure and convenient in operation, the effect is showing, the practicality is strong, can improve large -scale complicated steel -casting product success rate, reduce the casting defect.
Description
Technical field
The utility model relates to the complicated Gating System for Casting Steel of a kind of casting large-scale.
Background technology
The large complicated casting steel casting of tradition generally adopts staged to pour into a mould or simple bottom filling, ensures that molten steel steadily flows to each position of foundry goods, does not need to arrange Ji Zhaquan and a fairly large number of ingate.This pouring type has the advantages such as making is simple, convenient, the easy operation of moulding, but also there is weak point: be only applicable to the relatively simple foundry goods of structure, once casting structure and complexity, abnormity, easily there is slag inclusion, cold shut in the product adopting this running gate system to pour into a mould out, water less than etc. casting flaw.The arrangement of tradition running gate system has larger limitation.
Have for Gating System for Casting Steel at present, as a kind of New-type cast steel running gate system that CN203470827G announces, comprise steel ball, V-type passage, the cup be connected in turn from top to bottom, sprue, cross gate and ingate, V-type channel setting is in the edge of cup, V-type channel slopes is arranged, between the center line of V row of channels and horizontal line, angulation is 10 ± 1 °, described steel ball is positioned on V-type passage, and V-type passage is also placed the block of a prevention steel ball downslide, described sprue is by epimere, hypomere be connected, the changeover portion of hypomere is formed, the diameter of epimere is greater than the diameter of hypomere, the epimere of sprue is also provided with a teeming road, teeming road is connected with epimere, the sprue gate in teeming road communicates with rising head, the diameter of described steel ball is between the diameter and the diameter of hypomere of sprue epimere.It is not suitable for large complicated Gating System for Casting Steel.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of structure simple, practical, easy to operate, can improve large complicated steel-casting product success rate, reduce the complicated Gating System for Casting Steel of the casting large-scale of cast casting defect.
The implementation of the utility model object is, the complicated Gating System for Casting Steel of casting large-scale, the tapping mouth of a river of cone-shaped gate cup brick is docked with sprue, sprue lower end is connected with Ji Zhaquan by middle gap bridge, Ji Zhaquan connects cross gate circle, the uniform several ingate in cross gate circle upper end, ingate upper end is connected with product stator, and product stator upper end arranges the rising head that Multiple Type carries out feeding, gives vent to anger; The sectional area of the sectional area < ingate of the sectional area < cross gate circle of sprue.
When using the utility model, the height of cone-shaped gate cup brick arranges the height being higher than product die cavity, in casting ladle, pouring molten steel is in cone-shaped gate cup brick, when molten steel arrives riser height 1/2 place, point rushes rising head, and molten steel fills up rising head, steel flow is when slag trap circle, oxidizing slag in molten steel will be blocked in the upper end of slag trap circle, and pure molten steel flows to cross gate circle, imports stator die cavity through ingate shunting.
The utility model connection and reasonable arrangement, structure are simple, easy to operate, Be very effective, practical, large complicated steel-casting product success rate can be improved, reduce cast casting defect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1, the tapping mouth of a river of cone-shaped gate cup brick 1 of the present utility model is docked with sprue 2, and sprue lower end is connected with collection slag circle 4 by middle gap bridge 3, and Ji Zhaquan connects cross gate circle, cross gate circle 5 upper end is uniformly distributed 13 ingates 6, and ingate 6 is directly connected with product stator 7.The sectional area of the sectional area < ingate 6 of the sectional area < cross gate circle 5 of sprue 2.
The uniform several ingate in cross gate circle upper end, ingate upper end is connected with product stator.Product stator die cavity 7 upper end arranges four kinds of models, the rising head of carry out feeding, giving vent to anger, and numbering is respectively 1#, 2#, 3#, 4#.
Sprue 2: cross gate circle 5: the sectional area ratio of ingate 6 is=1:1.4:6.9.
When using the utility model, the height of cone-shaped gate cup brick arranges the height being higher than product die cavity, and in casting ladle, pouring molten steel is in cone-shaped gate cup brick 1, when molten steel arrives riser height 1/2 place, pass through point again and rush rising head to reach the object that molten steel fills up rising head, finally play the effect of feeding.Molten steel is when middle gap bridge 3 arrives rapidly slag trap circle 4, and the oxidizing slag in molten steel will be blocked in the upper end of slag trap circle 4, and pure molten steel flows to cross gate circle 5, thus reduces the slag inclusion of the casting of product.Reach fast through 13 ingates 6 again, stable filling stator die cavity.Four kinds of model rising heads that stator die cavity distributes above play a part to reduce casting flaw to product feeding.
