Abstract
A kind of middle-size and small-size hydraulic open flow-stabilizing casting system of ironcasting, it is made of top box and nowel, ingate is set in top box, cross gate is set on nowel, cross gate connects filter block, and filter block connects sprue, and filter block is ceramic foam filter, the sectional area that the sectional area of ingate is greater than cross gate is greater than the sectional area of sprue, and the sectional area of filter block is not less than the sectional area of times sprue.The middle-size and small-size hydraulic open flow-stabilizing casting system of ironcasting of the utility model solves the problems, such as the casting flaws such as medium and small oilhydraulic engineering valve sand hole, slag blister, mitigates iron liquid and washes away harm to fuse, improves product yield.
Description
Technical field
The utility model relates to casting mould technical fields.
Background technique
Oilhydraulic engineering valve generally uses sand casting process to produce, since medium and small oilhydraulic engineering valve substance is lighter
Frequently with enclosed pouring technology, positive-pressure gating system design is intended to it with the stronger dirty ability of gear, but fills type liquid
The fast speed of stream, scouring force is big, is easy to produce splash, if sand mold intensity not enough often leads to sand holes defect and oxidizing slag lacks
It falls into, it might even be possible to thrust tiny sand core.
Utility model content
In order to solve the above problem existing for positive-pressure gating system, the utility model provides a kind of middle-size and small-size hydraulic casting
The open flow-stabilizing casting system of ironware.
The utility model technical solution used for the above purpose is: a kind of middle-size and small-size hydraulic ironcasting is open
Flow-stabilizing casting system, is made of top box and nowel, and ingate is set in top box, and cross gate is set on nowel, and cross gate connects
Filter block is taken over, filter block connects sprue.
The filter block is ceramic foam filter.
The sectional area that the sectional area of the ingate is greater than cross gate is greater than the sectional area of sprue, the sectional area of filter block
Not less than the sectional area of sprue again.
The middle-size and small-size hydraulic open flow-stabilizing casting system of ironcasting of the utility model, solves medium and small oilhydraulic engineering
The problem of the casting flaws such as valve sand hole, slag blister mitigates iron liquid and washes away harm to fuse, improves product yield.
Detailed description of the invention
Fig. 1 is the middle-size and small-size hydraulic open flow-stabilizing casting system top box structure chart of ironcasting of the utility model.
Fig. 2 is the middle-size and small-size hydraulic open flow-stabilizing casting system nowel structure chart of ironcasting of the utility model.
In figure: 1, ingate, 2, cross gate, 3, filter block, 4, sprue, 5, top box, 6, nowel.
Specific embodiment
The middle-size and small-size hydraulic open flow-stabilizing casting system structure of ironcasting of the utility model is as depicted in figs. 1 and 2, by upper
Case 5 and nowel 6 are constituted, and ingate 1 is set in top box 5, and cross gate 2 is set on nowel 6, and cross gate 2 connects filter block 3,
Filter block 3 connects sprue 4, and filter block 3 is ceramic foam filter.The setting of ingate 1 in top box 5, cross-sectional dimension with
Cross gate 2 is proportional, and 2 sectional area of cross gate and 3 sectional area of filter block are proportional, 3 sectional area of filter block with directly pour
4 sectional area of road is proportional, 1 sectional area of ingate > 2 sectional areas of cross gate > sprue, 4 sectional area, and 3 sectional area of filter block >=
3 times of 4 sectional areas of sprue.Unchoked running system technological design is conducive to the Stable Filling of iron liquid, and foamed ceramics filter can have
Effect blocks iron liquid inclusion to invade casting mold.
It is designed using open flow-stabilizing casting system process, and cooperates appropriate filter, cross gate uses lower placement location simultaneously
It is connected directly with filter, guidance iron liquid is set on ingate and enters riser, when the open large percentage of each unit, molten metal is easy
Full of running gate system, fill that type is steady, the scouring force of type chamber reduced, cooperate suitable filter can meet the ability of pushing off the slag with
And improve the molten metal type of flow, it again can effective pushing off the slag to achieve the effect that steadily to become a mandarin.Very by trial-production using effect
It is good, sand mold scouring force is reduced, has prevented spraying state, sand holes defect and oxidizing slag defect are substantially reduced, and tiny core is thrust
Situation also seldom occurs.
