Abstract
The utility model relates to an integral casting die for a high-tension switch large aluminum alloy tank body. The integral casting die comprises an upper box sand mold, a lower box sand mold, a sprue cap, a downsprue, a cross sprue, a filtering slag trap, risers and denseners and is characterized in that: the upper part of the upper box sand mold is provided with the sprue cup; the sprue cup is connected with the downsprue arranged in the sand mold; the downsprue is connected with the cross sprue; an aluminum liquid inlet of the cross sprue is provided with the filtering slag trap; both ends of the cross sprue are connected with slit gates; the slit gates are communicated with a mold cavity; the upper box sand mold is provided with the risers which are communicated with the mold cavity; and cast iron denseners are embedded in the sand mold. The integral casting die has the advantages that: the method is easy to operate; the processes are less; the phenomena of shrinkage porosity, shrinkage cavity and slag pores inside the produced tank body are prevented; the product yield is high; and the cost is low.
Description
Technical field
The utility model relates to the foundry engieering territory, particularly a kind of monoblock cast mould of high-voltage switch gear large aluminum alloy tank body.
Background technology
The contour dimension of high-voltage switch gear large aluminum alloy 054 tank body is Ф 900 * 4000mm, wall thickness 20mm, and net weight 700kg, at present; High-voltage switch gear large aluminum alloy 054 tank body adopts casting to add the method production of welding: tank body is divided into three sections, and two end flanges adopt alloy sand mold or metal-mold low-pressure casting to cast out, and middle piece housing adopts aluminium sheet to be welded; Or adopt alloy to cast out, with three sections assembly weldings together, it is many that the method exists the production process operation then; Production cycle is long, the shortcoming that cost is high, in recent years; Domestic and international all at the technique for integral casting of developing the large aluminum alloy tank body, but because the tank body super large, the monoblock cast poured weights is often above 1.5 tons; Have the one whole difficult forming, shrinkage porosite, shrinkage cavity, slag pore are serious, can't satisfy tensile strength 275MPa, percentage elongation 2%, withstand voltage 800kPa, leak rate 1 μ g/m
2The problem of technical requirements such as s, and can't produce qualified products.
Summary of the invention
The purpose of the utility model provides a kind of monoblock cast mould that can enough make the high-voltage switch gear large aluminum alloy tank body of super large tank body.
The utility model is to realize like this; It comprises top box sand mold, nowel sand mold, cup, sprue, cross gate, filtration dirt trap, rising head and chill, it is characterized in that being provided with cup on top box sand mold top, and the cup sprue interior with being arranged on sand mold is connected; Sprue is connected with cross gate; Aluminium liquid entrance point at cross gate is provided with the filtration dirt trap, and the cross gate two ends are connected with the slit running channel, and the slit running channel communicates with die cavity; The top box sand mold is provided with the rising head that communicates with die cavity, in sand mold, is inlaid with the cast iron chill.
The beneficial effect of the utility model is, method is simple to operate, and operation is few, and the tank interior of producing does not have shrinkage porosite, shrinkage cavity, slag pore phenomenon, and yield rate is high, and is with low cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further description.
The structural representation of the monoblock cast mould of Fig. 1 high-voltage switch gear large aluminum alloy tank body,
The monoblock cast die worker of Fig. 2 high-voltage switch gear large aluminum alloy tank body makes sketch map.
The specific embodiment
Shown in Fig. 1-2; The monoblock cast mould of this high-voltage switch gear large aluminum alloy tank body comprises cup 1, sprue 2, filters dirt trap 3, cross gate 4, slit running channel 5, rising head 6, chill 7, top box sand mold 8, integral sand core 9 and nowel sand mold 10, is provided with cup 1 on top box sand mold 8 tops, and cup 1 sprue 2 interior with being arranged on sand mold is connected; Sprue 2 is connected with cross gate 4; Aluminium liquid entrance point at cross gate 4 is provided with filtration dirt trap 3, and cross gate 4 two ends are connected with slit running channel 5, and slit running channel 5 communicates with die cavity; Top box sand mold 8 is provided with the rising head that communicates with die cavity; In sand mold, be inlaid with cast iron chill 7, before its operation principle is casting, cup 1 and sprue 2 junctions clogged with stopper.During cast, aluminium liquid is poured in the cup 1, aluminium liquid reach a certain height and liquid level when steady, and corkage injects cup with constant speed with aluminium liquid simultaneously.Behind the corkage, aluminium liquid at first gets in the sprue 2, gets into cross gate 4 through filtering after dirt trap 3 filters, removes the gred then, gets into subsequently in the slit running channel 5, gets into die cavity at last, when aluminium liquid is full of rising head 6, stops cast.After casting solidification shrank beginning, liquid level can descend in the rising head 6, at this moment more certain aluminium liquid is directly poured in the rising head 6, carries out feeding.So repeatedly several times; Liquid level no longer changes in rising head 5, adopts cup 1, cross gate 4 and slit running channel 5 to make aluminium liquid fill type with more stable speed, obtains pure aluminium liquid through filtering dirt trap 3 filter cleaners; Through the sand mold exhaust, alleviate or eliminate the slag pore; Adopt chill and rising head reasonably combined, set up that solidify earlier at the chill position, the consecutive solidification principle of rising head position after coagulation, reduce shrinkage porosite and be inclined to, produce qualified foundry goods.
