In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of engineering machinery hydraulic solenoid valve casting
Sand core mould, innovative point are: including sandbox, sand mold and sand core group；The sand core group is arranged on sand mold, sand core group and sand mold
Setting together constitutes casting type chamber in sandbox with sandbox, and sand core group and sand mold are located on sandbox；
The sandbox is in open hollow box body structure, and the notch with sand mold cooperation is provided on the two sides of sandbox；
The sand mold is embedded in the notch in sandbox with the end face of sandbox and on sandbox and cooperates；The sand mold rectangular frame structure, sand
It is in nick shaped at wherein one end angle of type；Sand mold is wherein provided with sand core group locating slot on an opposite two sides inner wall；
The sand core group includes sand core block, sand core frame and sand core pedestal, and the sand core pedestal is respectively embedded in sand mold inner wall
Sand core group locating slot in, the sand core frame is connected horizontally on sand mold on the side of not set sand core group locating slot, the sand
It is respectively arranged with and sand core pedestal is connect on the inner wall of sand mold side sand core item on the both ends of sand mold inner wall on core frame；It is described
If being provided on centre on sand core frame and sand core pedestal is connect on the inner wall of the sand mold other side dry sand core block；
The sand core block be split type structure include the first sand core block, the second sand core block and third sand core block, described first
Sand core block, the second sand core block and third sand core block are sequentially coaxially arranged on sand core frame.
Further, the sand core frame is in a pair of of cylindrical-shaped structure, this is connected to sand to columned sand core both ends
In type, the gap for accommodating sand core block is provided among sand core frame.
Further, sand core on the first sand core block, the second sand core block and third sand core block and sand mold other side inner wall
The insertion connection type of horizontal direction is used between pedestal.
Utility model has the advantages that
1) by casting of the combination as hydraulic buttery valve between sand core group and sand mold in the utility model, use is hollow
The sand core structure of formula, so that sand core is more light, and reduces sand using amount, cost waits until to reduce, and selects reasonable parting position,
The minimum number for making assembly of sand core in the case where reducing and using loose piece simplifies the production of hydraulic buttery valve casting
Journey.
