Problems solved by technology
[0002] In the production and casting process of the valve, due to the long-term use of the mold, the mold will be deformed under the temperature difference between cold and hot, and the deformed mold will cause a certain deformation of the workpiece, especially in the pipeline connection In the casting of parts, there will be a certain error in the position of the connecting hole of the valve cast by the deformed mold. This error will affect the coaxiality of the connecting pipes on both sides of the valve, and will bring a certain error to the installation. The pipe not only affects the appearance, but also the inclined pipe is subjected to radial force for a long time. After a long time, the strength of the pipe will be affected, and the installation hole of the valve core will also have a certain error. The inclined valve core will affect the sealing degree of the valve. At the same time, it will also bring some difficulties to the installation
[0003] In addition, for the internal cavity of the valve, the internal cavity forming part of the traditional valve casting is integrated with the external mold. After the mold is deformed, the roundness of the internal cavity of the valve will also change, and the deformed internal cavity will affect In the later stage, the thread of the installation position of the valve pipe will be processed, and at the same time, the wall surface of the valve after processing the thread will have the problem of uneven thickness, which will bring hidden dangers to the strength of the valve.

The invention discloses a centering valve casting mold. The shape and position of the valve casting cavity of the mold are corrected through a built-in valve cavity forming component and a correcting component, and the tubular valve cavity forming part can ensure the uniformity of the valve cavity. Axiality, straightness and roundness, and at the same time, the straightening component can easily adjust the mold through a simple static pressing structure, the operation is simple, the structure is simple, and the production is convenient.
Description
technical field [0001] The invention relates to a centering valve casting mold, in particular to a valve casting mold capable of centering and correcting each cavity of a valve. Background technique [0002] In the production and casting process of the valve, due to the long-term use of the mold, the mold will be deformed under the temperature difference between cold and hot, and the deformed mold will cause a certain deformation of the workpiece, especially in the pipeline connection In the casting of parts, there will be a certain error in the position of the connecting hole of the valve cast by the deformed mold. This error will affect the coaxiality of the connecting pipes on both sides of the valve, and will bring a certain error to the installation. The pipe not only affects the appearance, but also the inclined pipe is subjected to radial force for a long time. After a long time, the strength of the pipe will be affected, and the installation hole of the valve core wi...
