Abstract
The utility model discloses a connecting lever box of a high-voltage electrical component. The connecting lever box comprises an upper cover, a bottom plate and side dies, wherein two side dies are arranged and distributed between the upper cover and the bottom plate; a cast area is formed in the middle; an opening is formed at the middle part of the upper cover; a combined steel core put from the opening of the upper cover is arranged inside the cast area; a cast is arranged in the middle of the combined steel core and the side dies at two sides; the combined steel core comprises a first core, a second core, a third core, a fourth core, a fifth core, a sixth core and a seventh core; the first core is of a square shape and arranged at the middle part of the combined steel core; the second core, the seventh core, the fourth core, the third core, the fifth core and the sixth core are orderly arranged at the periphery of the first core along the clockwise direction. By adopting the connecting lever box, the casting yield is improved; the casting cost is reduced; an energy source is saved; the environmental pollution is reduced.
Description
Technical field
The utility model relates to high voltage electric equipment field, is specially a kind of high-voltage electrical apparatus element Crankarm box.
Background technology
At present, for high-voltage electrical apparatus element Crankarm box, product design structure is that core cavity middle part is that size is larger, and foundry goods both ends open portion size is less.Special construction due to product design, whole steel core cannot take out, most of producer that casts all adopts punching block resin sand core casting technique to produce, because the employing of resin sand causes, production efficiency is lower, Mechanical processing of casting face is prone to the sand hole defect that knockout causes, and the higher and casting process of casting cost is because the burning environmental pollution of resin is larger.
Summary of the invention
The utility model, for above weak point, provides a kind of high-voltage electrical apparatus element Crankarm box, improves qualified casting, reduces the object of casting cost, saving the energy and reduction environmental pollution.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-voltage electrical apparatus element Crankarm box, include upper cover, base plate and Bian Mo, and described limit mould is set to two,
distributebetween upper cover and base plate, connect upper cover and base plate, the middle foundry goods district that forms, described upper cover middle part is provided with opening, in foundry goods district, be provided with the combination steel core of putting into from the opening part of described upper cover, the centre of described combination steel core and dual-side mould is foundry goods, described combination steel core includes the first fuse, the second fuse, the 3rd fuse, four-core, the 5th fuse, the 6th fuse, the 7th fuse, described the first fuse is the square middle part that is positioned at combination steel core, the surrounding of described the first fuse is disposed with the second fuse in the direction of the clock, the 7th fuse, four-core, the 3rd fuse, the 5th fuse, the 6th fuse.
The beneficial effects of the utility model are: the project organization that improves fuse in the situation that meeting casting pouring technique, by resin sand sand core structure, change split steel core cast structure into, forging type changes punching block split steel core founding method, the employing of having stopped resin sand into by the casting of punching block resin sand core; After improving, qualified casting is brought up to more than 93% by 75%, and production efficiency is enhanced about more than once, and effectively reduces the pollution of resin burning to environment simultaneously.
Accompanying drawing explanation
It shown in Fig. 1, is structural representation of the present utility model;
It shown in Fig. 2, is the structural representation of combination steel core;
Figure 3 shows that and improve front conceptual scheme.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown be a specific embodiment of the present utility model, a kind of high-voltage electrical apparatus element Crankarm box, include upper cover 1, base plate 2 and Bian Mo 3, described limit mould 3 is set to two, the mid portion left and right that is distributed in upper cover 1 and base plate 2 is arranged, the middle foundry goods district that forms, described upper cover 1 middle part is provided with opening, in foundry goods district, be provided with the combination steel core 4 of putting into from the opening part of described upper cover 1, described combination steel core 4 is foundry goods 5 with the centre of dual-side mould, described combination steel core 4 includes the first fuse 41, the second fuse 42, the 3rd fuse 43, four-core 44, the 5th fuse 45, the 6th fuse 46, the 7th fuse 47, described the first fuse 41 is the square middle part that is positioned at combination steel core 4, the surrounding of described the first fuse 41 is disposed with the second fuse 42 in the direction of the clock, the 7th fuse 47, four-core 44, the 3rd fuse 43, the 5th fuse 45, the 6th fuse 46.
After casting pouring completes, take out combination steel core 4, first with oil cylinder, take out the first fuse 41, then by manual mode, take out the second fuse 42, take out again the 3rd fuse 43, then take out respectively in order fuse four-core 44, the 5th fuse 45, the 6th fuse 46, the 7th fuse 47.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
