Description

A kind of cast filter

Technical field

Cast filtration art is the utility model is related to, is especially a kind of cast filter.

Background technology

For aluminum alloy gravity casting, aluminium ingot is made up of a variety of alloying components, such as aluminium, magnesium, zinc, copper etc., molten When solution, aluminium ingot and atmosphere, oxygen and active metal react, and generate oxide.

Although the degasification slag hitting of melting, which can eliminate, melts most of oxide caused by process, oxidation is one and held Continuous process.After degasification slag hitting, aluminium liquid still in continuous and air contact, produces oxide.Cast worker scoop aluminium when Wait, some swim in the oxide on aluminium liquid surface, it is easy to scooped to inside spoon, be introduced into mold cavity afterwards.

If oxide enter die cavity after, majority is retained in rising head, also have one point it is partially solidified in inside workpiece.Make Into tissue looseness, casting strength reduces, if casting is tubing and housing, causes sealing to decline, cause pipeline gas leakage.

If oxide has been set in cast(ing) surface, to this kind of workpiece ball blast, loose place is smashed by ball blast sand, casting Surface has sand holes, influences outward appearance.

Measure before is to increase degasification slag hitting dynamics, reduces oxide as far as possible and exists.For the part of ball blast, Soldering finishing is carried out for surface；The waste in man-hour will certainly be caused, is caused bad；Therefore need to be improved.

Utility model content

Therefore, in order to solve above-mentioned deficiency, the utility model provides a kind of cast filter herein；Screen pack is set Most of oxide can have been filtered out, has reduced oxide into the risk in die cavity, therefore has improved cast-internal and outer Component matter.Meanwhile change filtered fluid net and do not need technical difficulty, the convenience of operation is ensure that, further increases work Make quality, casting is bad to be reduced to 1% from 10%, greatly reduces fraction defective.

The utility model is accomplished by the following way, and constructs a kind of cast filter, including casting ladle, lower plate and on Plate；One end that pouring cup and upper plate are provided with the upper plate is movably arranged on to pour and wrapped；Have in the middle part of lower plate cast cavity and Lower plate is integrally attached to pour and wrapped, and screen pack is provided with below the cast cavity.Set screen pack can be with the utility model Most of oxide has been filtered out, has reduced oxide into the risk in die cavity, therefore improve cast-internal and outer component Matter.Meanwhile change filtered fluid net and do not need technical difficulty, the convenience of operation is ensure that, further increases as received basis Amount, casting is bad to be reduced to 1% from 10%, greatly reduces fraction defective.

As the improvement of above-mentioned technical proposal, one kind cast filter, the upper plate is set by hinge activity Put and wrap pouring.The activity for realizing upper plate here by hinge is overturn, and hinge cost is low, and it is very easy to implement.

As the improvement of above-mentioned technical proposal, one kind cast filter, the casting ladle generally cuboid knot Structure；The casting ladle of rectangular parallelepiped structure is used herein, it is reasonable in design, not excessive space-consuming and more aluminium liquids can be accommodated.

As the improvement of above-mentioned technical proposal, one kind cast filter, the casting ladle is internally provided with pushing off the slag Plate；Casting ladle is internally formed accommodating chamber and cast chamber by slag trap；Leave gap in slag trap bottom.One piece of pushing off the slag is set herein Plate, it can further remove the impurity of the oxide on molten metal surface and molten metal itself, ensure the quality of cast finished product and pure Cleanliness, hence it is evident that reduce impurity content, and then improve

Product qualified rate.

As the improvement of above-mentioned technical proposal, one kind cast filter, clearance height 20-40mm.

As the improvement of above-mentioned technical proposal, one kind cast filter, it is provided with below the screen pack Deflector, deflector are inclined inside casting ladle.Deflector can allow aluminium liquid following current, prevent excessive spluttering.

As the improvement of above-mentioned technical proposal, one kind cast filter, baffle surface has multiple tracks arc Guiding gutter.

As the improvement of above-mentioned technical proposal, one kind cast filter, a diameter of 20-50mm of pouring cup.
