Description
Technical field
The present invention relates to a kind of butterfly valve casting die, particularly a kind of high-performance dish valve foundry goods.
Background technology
For large-scale butterfly valve, producer is generally cast by the way of molding sand casting and is formed, in butterfly valve sandbox parting
Horizontal die joint, i.e., the shape for not destroying circular ports is adopted to carry out to subdivision type, the advantage of this mode in the selection in face
It is that parting is simple, casting is easy；But due to the spheroidal graphite cast-iron cast, 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.For rough casting needs to carry out secondary production, the loose surface in such top can be broken when secondary operation is carried out
Bad its structure, causes foundry goods to destroy.Therefore, existing technology has that foundry goods surface structure is loose, the quality that foundry goods is overall
The low problem of poor and product percent of pass.
The content of the invention
It is an object of the present invention to provide a kind of high-performance dish valve foundry goods.It has casting structure closely, foundry goods total quality it is good
And product qualified rate it is high the characteristics of.
Technical scheme：A kind of high-performance dish valve foundry goods, including cope and drag box；It is provided with cope and cuts
Upper impression of the face for semicircular structure, is provided with the upper core that section is semi-circular structure in the middle part of upper impression, mo(u)ld top half cavity wall is provided with and cuts
Upper, annular groove-type core of the face for semi-circular shape structure, upper, annular groove-type core two ends are provided with upper orifice die cavity, upper orifice
The upper gland core being connected with upper core is provided with die cavity；Lower impressions are provided with the drag box, are provided with the middle part of lower impressions and are cut
Lower core of the face for semi-circular structure, mo(u)ld bottom half cavity wall are 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, and the lower axle bore type contacted with lower core is provided with lower nozzle die cavity
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 a kind of aforesaid high-performance dish valve foundry goods, the cope is provided with and pours pipe, pours pipe and riser feeding type
Chamber is connected.
In a kind of aforesaid high-performance dish valve foundry goods, the drag box bottom is provided with pressure sensor, and pressure sensor connects
Controller is connected to, controller is connected with positioned at the flow valve poured on pipe.
Compared with prior art, parting method of the present invention by the original butterfly valve die cavity in sandbox of change, with butterfly valve pipe
The longitudinal surface that mouth center line is located is die joint, and the upper and lower die cavity for forming semi-circular structure in upper and lower sandbox respectively replaces existing
Upper and lower die cavity in sandbox with the horizontal face of butterfly valve as die joint so that two circular surfaces of butterfly valve are not last shapings, are not required to
Carry out last feeding so as to which circular surface has close architectural characteristic so that butterfly valve is not allowed when secondary operation is carried out
It is fragile, the total quality of butterfly valve foundry goods is improved, the qualification rate of finished product is improve；And according to spheroidal graphite cast-iron from the bottom up
By the characteristic constantly up shunk in casting cycle, riser feeding die cavity is set in upper impression upper end, for casting
Butterfly valve afterwards carries out feeding, and defect is concentrated on rising head so that for placing circular communication port and the butterfly valve surface of butterfly valve plate
Shrink uniform, close structure.In sum, the present invention have casting structure closely, foundry goods total quality is good and finished product is qualified
The characteristics of rate is high.
In addition, by arrange it is multiple pour pipe, and pipe will be poured be connected with riser feeding die cavity, and both improve to cast and imitated
Rate, ensure that the quality of casting again；Meanwhile, it is engaged with pressure sensor and flow valve by controller, effectively can be controlled
The casting quality of molten iron processed, reduces and wastes.
