Description
Technical field
The utility model belongs to technical field of mold, more particularly to one kind is used to prepare high-pressure high-flow hydraulic multitandem valve
Mould.
Background technology
Hydraulic multitandem valve is the core control part of engineering machinery, applied to all engineering machinery, it is desirable to it is high pressure resistant and
Its is highly integrated, is not allow for any casting flaw and scale error.Frock clamp is generally used in the prior art by multi-way valve
Oil outlet core print and plug core print are fixed on spool hole seat sand core by way of bonding and form integral sand core, are then torn open
Casting mould entirety is formed except integral sand core is put into cavity by frock clamp.During cast casting, since sand core will be by
The impact of high temperature (1375-1410 DEG C) molten iron, sand core are difficult not to be subjected to displacement, and make casting error larger, cause casting to be scrapped.
Utility model content
A kind of sand core accurate positioning, the punching of resistance to molten iron are provided the purpose of the utility model is to overcome the deficiencies in the prior art
The strong mould for being used to prepare high-pressure high-flow hydraulic multitandem valve of brush ability.
In order to solve the above technical problems, the mould for being used to prepare high-pressure high-flow hydraulic multitandem valve of the utility model,
Include the upper die and lower die of mutual pairing, formed with cavity between the upper die and lower die, sand core is installed in the cavity
Fixed cover board, the cavity and the sand core form the casting chamber to match with hydraulic multitandem valve shape between fixing cover board,
There is spool hole seat sand core in the casting cavity indoor location, the sand core is fixed cover board and is supported and fixed on by the support feet of both sides
On spool hole seat sand core, the sand core is fixed on cover board and is respectively equipped with and multi-way valve oil outlet core print and plug core print size
Matched location hole, the multi-way valve oil outlet core print and plug core print fix cover board location and installation by the sand core and exist
In the casting cavity room.
Further, the sand core is fixed on the outer surface of cover board and scribbles anti-stick coating.
Further, the on both sides of the upper end of the spool hole seat sand core be equipped with the matched slot of the support feet, it is described
Support feet is integrally formed with sand core fixation cover board and Matching installation is in the slot.
Compared with prior art, the utility model is simple in structure, convenient and practical, by by multi-way valve oil outlet core print and
Plug core print is fixed on sand core and fixes on cover board, can keep out washing away for molten iron in casting process, during core finishing, core finishing operator
Error can be very easily held, meets the needs of casting, cast casting efficiency is substantially increased, is greatly reduced casting cost.

Embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1-Fig. 3, a kind of mould for being used to prepare high-pressure high-flow hydraulic multitandem valve, including mutual pairing are upper
Mould 1 and lower die 2, formed with cavity 3 between upper mold 1 and lower dies 2, sand core are provided with cavity 3 and fixes cover board 4, cavity 3 and sand
Core is fixed between cover board 4 formed with the casting chamber to match with hydraulic multitandem valve shape, and the top end face that sand core fixes cover board 4 is tight
The top surface of cavity is pasted, has spool hole seat sand core 5 in casting cavity indoor location, sand core fixes support feet 6 of the cover board 4 by both sides
Support is fixed on spool hole seat sand core 5.Sand core is fixed on cover board 4 and is respectively equipped with and multi-way valve oil outlet core print and plug sand core
The head matched location hole 7 of size, multi-way valve oil outlet core print, plug core print and spool hole seat sand core 5 collectively form hydraulic pressure
The integral sand core of multi-way valve.Multi-way valve oil outlet core print and plug core print are inlaid in corresponding location hole.Multi-way valve goes out
Hydraulic fluid port core print and plug core print fix 4 location and installation of cover board in the casting cavity room by sand core.
Removed for convenience of by sand core fixation cover board 4 from casting, fixed in sand core on the outer surface of cover board 4 and scribble anti-snearing
Layer, which is WPS-180 releasing agents.
The utility model is fixed on cover board 4 by the way that multi-way valve oil outlet core print and plug core print are fixed on sand core,
Washing away for high temperature liquid iron can be kept out in casting process, only needs from casting to tear sand core fixation cover board 4 open after casting complete
Except i.e. can obtain multiway valve casting.By setting sand core to fix cover board 4, core finishing operator's core finishing is also convenient for, ensures that multi-way valve goes out
Position relationship between hydraulic fluid port core print and plug core print, improves cast casting efficiency, reduces casting cost.
