The present invention relates to a kind of engineering machinery hydraulic solenoid valve casting sand core moulds, it is characterised in that：Including sandbox, sand mold and sand core group；The sand core group is arranged on sand mold, and sand core group and sand mold setting together constitute casting cavity in sandbox with sandbox, and sand core group is located in sand mold on sandbox；It is used as the casting of hydraulic buttery valve in the present invention by the combination between sand core group and sand mold, using the sand core structure of hollow type, so that sand core is more light, and reduce sand using amount, cost waits until to reduce, rational parting position is selected, in the case where reduction uses loose piece so that the minimum number of assembly of sand core, simplifies the production process of hydraulic buttery valve casting.
Description
Technical field
The present invention relates to foundary industry field more particularly to a kind of engineering machinery hydraulic solenoid valve casting sand core moulds.
Background technology
The pattern using casting of general hydraulic buttery valve is molded, its inner cavity of casting sand core is complex, wherein wrapping
A large amount of raised block is contained, multiple with the extraneous macropore communicated, generally also multiple locating pieces are by sandbox between sandbox shell
The cavity of formation is divided into two, in addition to this also sand core, these all increase difficulty to the design of sand core.Work traditional at present
The assembly of sand core process of journey mechanical-hydraulic solenoid valve is more, needs to use many loose piece and sand core, this traditional sand core knot
The shortcomings that structure is：It needs to open core box and more loose pieces, production process is complicated, time-consuming and laborious, increases cost more.Therefore it needs
Want that one kind can be positioned quickly and sand using amount is few, efficient sand core realizes the production of engineering machinery hydraulic buttery valve.
Invention content
The technical problem to be solved in the present invention is to provide a kind of engineering machinery hydraulic solenoid valve casting sand core moulds, can solve
Pour in mold that sand using amount is big, sand core is more in general engineering machinery hydraulic solenoid valve, loose piece mostly with problem of high cost.
In order to solve the above technical problems, the technical scheme is that：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
Casting cavity is together constituted with sandbox in sandbox, sand core group is located in sand mold on sandbox；
The sandbox is in open hollow box body structure, and the notch coordinated with sand mold is provided on the two sides of sandbox；
The sand mold is embedded in the end face in sandbox with sandbox and the notch on sandbox coordinates；The sand mold rectangular frame structure, sand
It is in nick shaped at wherein one end angle of type；It is provided with sand core group locating slot on the opposite two sides inner wall of sand mold wherein one；
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, which is connected horizontally on sand mold, not to be arranged on the side of sand core group locating slot, the sand
It is respectively arranged on the both ends of sand mold inner wall on core frame and sand core pedestal is connect on the inner wall of sand mold side sand core item；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 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.
The advantage of the invention is that：
1) it is used as the casting of hydraulic buttery valve in the present invention by the combination between sand core group and sand mold, using hollow type
Sand core structure so that sand core is more light, and reduces sand using amount, and cost waits until to reduce, and selects rational parting position, is subtracting
So that the minimum number of assembly of sand core, simplifies the production process of hydraulic buttery valve casting in the case of using loose piece less.
