Left and right supporting plane on described supporting base is loosed core is respectively equipped with projection, makes to be provided with on the valve body supporting base of shaping to install and fix the hole accordingly.
The beneficial effects of the utility model are:
1),, left and right supporting base is arranged to whole the connection because loosing core, the supporting base that promptly constitutes whole shape is loosed core, in press casting procedure, can be disposable the left and right supporting base casting forming of valve body, and guarantee that its degree of balance meets the requirement of mounting process worker difference, avoiding loosing core because of left and right supporting base is not an integral body, cause in the press casting procedure, depanning influences to be subjected to left and right supporting base to loose core respectively, causes the degree of balance instability of complete machine, produces deviation and makes the defective of the valve body distortion of shaping;
2), Zheng Ti supporting base is loosed core and has been replaced the left and right supporting base of split setting to loose core, make it disposable the supporting base part casting forming of valve body, the left and right supporting base outer face of its casting forming is smooth shape, and be on the same horizontal plane, further machining is saved expending of manufacturing procedure;
