Abstract
The utility model relates to the sandbox of a kind of spheroidal graphite cast-iron casting rapid shaping large slewing parts, comprise upper part casing and lower part casing, molding sand is filled with in the space that upper part casing and lower part casing enclose, die cavity is provided with in molding sand, upper part casing is provided with cup and cap mouth, it is characterized in that: the described excircle at die cavity is embedded with chill, the layer of sand of 3 ~ 5mm between the medial surface of described chill and die cavity inside, described chill is assembled by several chill monomer; Described cap mouth is provided with three, is distributed on upper part casing respectively, and the internal diameter of each cap mouth is 18 ~ 20mm.Adopt technique scheme, compare with traditional sandbox, greatly reduce its cost of manufacture, alleviate the weight of whole sandbox; Cap mouth now main become exhaust outlet, feeding amount in addition reduces greatly, thus avoids the defect that exists because feeding is improper.
Description
Technical field
The utility model belongs to large slewing parts casting technology field, particularly relates to the sandbox of a kind of spheroidal graphite cast-iron casting rapid shaping large slewing parts.
Background technology
As everyone knows, upper part casing and lower part casing is comprised at casting model powder case, molding sand is filled with in the space that upper part casing and lower part casing enclose, die cavity is provided with in molding sand, upper part casing is provided with cup and cap mouth, supply consecutive solidification along with metallic solution in actual casting process is shaping, carries out feeding finally by cap mouth; Generally adopt cap mouth compared with large diameter to carry out feeding for large slewing parts at cast type with regard to current, because part is larger, so the amount of feeding is also comparatively large, the volume and weight of cap mouth is also comparatively large, and in actual feeding engineering, cap mouth place easily occurs casting flaw; A such as main part as shown in Figure 4, its maximum outside diameter is 500mm, and so general needs three cap mouths are uniform to be arranged on upper part casing, and the internal diameter of each cap mouth is about 120mm, thus increases the weight of whole sandbox, reduces the convenience of operation.
Existingly generally to adopt with the following method to reduce cap mouth diameter, 1, additional chill is adopted, although foundry goods thermal center can be realized preferably to be solidified, but the manufacture of external chill is comparatively complicated, the different foundry goods of root needs the external chill of design specialized, then need the technique such as molding, moulding just can complete, chance can not utilize by secondary; 2, adopt negative pressure cooling, in sandbox, namely arrange that negative tube solidifies to the thermal center completing foundry goods; The method overcomes more existing problems, but its manufacturing cost, comparatively strict to the control of negative pressure, but also need special configuration negative pressure equipment.
Summary of the invention
The utility model provides a kind of structure simple, easy to use, with low cost for solving in known technology the technical problem that exists, can reuse, overcome the sandbox that traditional sandbox exists the in-problem a kind of spheroidal graphite cast-iron casting rapid shaping large slewing parts of cap mouth.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of sandbox of spheroidal graphite cast-iron casting rapid shaping large slewing parts, comprise upper part casing and lower part casing, molding sand is filled with in the space that upper part casing and lower part casing enclose, die cavity is provided with in molding sand, upper part casing is provided with cup and cap mouth, it is characterized in that: the described excircle at die cavity is embedded with chill, the layer of sand of 3 ~ 5mm between the medial surface of described chill and die cavity inside, described cap mouth is provided with three, be distributed on upper part casing respectively, the internal diameter of each cap mouth is 18 ~ 20mm.
The utility model can also adopt following technical measures:
Described chill is assembled by several chill monomer, and the two ends of each chill monomer are provided with correspondence and are provided with draw-in groove and projection, and described draw-in groove is consistent with protruding shape.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, namely built-in chill technology is adopted, according to the feature of slewing parts, chill is embedded with at the excircle of die cavity, in order to not affect the external form of product, existing internal diameter is that the cap mouth of 120mm has narrowed down to 18 ~ 20mm by the layer of sand of 3 ~ 5mm like this between the medial surface and die cavity inside of chill, greatly reduce its cost of manufacture, alleviate the weight of whole sandbox; Cap mouth now main become exhaust outlet, feeding amount in addition reduces greatly, thus avoids the defect that exists because feeding is improper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is chill monomer structure schematic diagram;
Fig. 3 is another kind of chill monomer structure schematic diagram;
Fig. 4 is slewing parts structural representation.
In figure: 1, upper part casing; 2, lower part casing; 3, molding sand; 4, die cavity; 5, cup; 6, cap mouth; 7, chill; 7-1, draw-in groove; 7-2, projection.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 to Fig. 3, a kind of sandbox of spheroidal graphite cast-iron casting rapid shaping large slewing parts, comprise upper part casing 1 and lower part casing 2, molding sand 3 is filled with in the space that upper part casing and lower part casing enclose, die cavity 4 is provided with in molding sand, upper part casing is provided with cup 5 and cap mouth 6, the described excircle at die cavity is embedded with chill 7, in order to not affect the external form of product, the layer of sand of 3 ~ 5mm between the medial surface of described chill and die cavity inside, described chill is assembled by several chill monomer, consult Fig. 3, the two ends of each chill monomer are provided with correspondence and are provided with draw-in groove 7-1 and protruding 7-2, described draw-in groove is consistent with protruding shape, in the mutual grafting of practical set formula, described cap mouth is provided with three, is distributed on upper part casing respectively, and the internal diameter of each cap mouth is 18 ~ 20mm.
Adopt built-in chill technology, according to the feature of slewing parts, be embedded with chill at the excircle of die cavity, compare with traditional external chill, greatly reduce its cost of manufacture, alleviate the weight of whole sandbox; Cap mouth now main become exhaust outlet, feeding amount in addition reduces greatly, thus avoids the defect that exists because feeding is improper.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
