Description
Technical field
The utility model is related to a kind of butterfly valve casting die, particularly a kind of high-performance dish valve casting.
Background technology
For large-scale butterfly valve, producer is generally cast by the way of molding sand casting and formed, in butterfly valve sandbox parting
Using horizontal die joint in the selection in face, i.e., the shape for not destroying circular ports is carried out to subdivision type, the advantage of this mode
It is that parting is simple, casting is easy；But it is due to the spheroidal graphite cast-iron of casting, its characteristic is to carry out reexpansion in casting cycle,
Contraction process is to shrink from the bottom up, temperature-fall period be from low toward high cooling, so may result in top casting region its
Surface porosity.Need to carry out secondary production for rough casting, the loose surface in such top can be broken when carrying out secondary operation
Its bad structure, causes casting to destroy.Therefore, existing technology has the quality that casting surface structure is loose, casting is overall
The low problem of poor and product qualification rate.
Utility model content
The purpose of this utility model is that there is provided a kind of high-performance dish valve casting.It has that casting structure is close, casting is whole
Weight is good and the characteristics of high product qualified rate.
The technical solution of the utility model：High-performance dish valve casting, including cope and drag box；It is provided with and cuts in cope
Face is that mo(u)ld top half cavity wall, which is provided with, to be cut provided with the upper core that section is semi-circular structure in the middle part of the upper impression of semicircular structure, upper impression
Face is the upper, annular groove-type core of semi-circular shape structure, and upper, annular groove-type core two ends are provided with upper orifice die cavity, upper orifice
Provided with the upper gland core being connected with upper core in die cavity；It is provided with to be provided with the middle part of lower impressions, lower impressions in the drag box and cuts
Face is the lower core of semi-circular structure, and mo(u)ld bottom half cavity wall is provided with the lower annular groove-type core that section is semi-circular shape structure, lower loop
Shape groove-type core two ends are provided with lower nozzle die cavity, lower nozzle die cavity provided with the lower axle bore type being in contact with lower core
Core；The upper impression upper end is provided with riser feeding die cavity；Butterfly valve body is provided between the upper impression and lower impressions.
In foregoing high-performance dish valve casting, the cope pours pipe and riser feeding die cavity phase provided with pipe is poured
Even.
In foregoing high-performance dish valve casting, the drag box bottom is provided with pressure sensor, and pressure sensor is connected with
Controller, controller is connected with positioned at the flow valve poured on pipe.
Compared with prior art, the utility model is by changing the parting method of original butterfly valve die cavity in sandbox, with butterfly
Longitudinal surface where valve mouth of pipe center line is die joint, and the upper and lower die cavity for forming semi-circular structure respectively in upper and lower sandbox is replaced
Using the horizontal face of butterfly valve as the upper and lower die cavity of die joint in existing sandbox so that two circular surfaces of butterfly valve are not last shapings,
Last feeding need not be carried out, makes its circular surface that there is close architectural characteristic so that butterfly valve is when carrying out secondary operation
Do not allow fragile, improve the total quality of butterfly valve casting, improve the qualification rate of finished product；And according to spheroidal graphite cast-iron from lower past
On casting cycle in by the characteristic constantly up shunk, in upper impression upper end, riser feeding die cavity is set, for pair
Butterfly valve after casting carries out feeding, defect is concentrated on into rising head so that circular communication port and butterfly valve for placing butterfly valve plate
Surface shrinkage is uniform, close structure.In summary, the utility model have that casting structure is close, casting total quality is good and
The characteristics of product qualified rate is high.
In addition, by set it is multiple pour pipe, and pipe will be poured be connected with riser feeding die cavity, and both improve casting effect
Rate, ensure that the quality of casting again；Meanwhile, it is engaged, can be effectively controlled with pressure sensor and flow valve by controller
The casting quality of molten iron processed, reduces and wastes.
