Abstract
A kind of air suction structure for being used for core frame under DISA lines and preventing that core from dropping, including lower core frame and lower core frame locating piece, it is characterized in that setting gradually the lower core frame suction hole of intercommunication, lower core frame locating piece suction hole and lower core frame locating piece air-breathing groove on lower core frame and lower core frame locating piece, vacuum suction structure is formed.Superiority：The planform is simple, ventilate smooth, it is easy to make, air-breathing slot structure increases compared to sucting hole structure area, be advantageous to the cooperation between core and lower core frame, avoid simultaneously core drop and core places unstable situation, core also disposably can be positioned over lower core inframe by lower core personnel, avoid repeating to place.Not only mitigate personnel labor intensity, size caused by the wasting of resources caused by also avoiding production line delay and batch production is bad.This structure is applied to lower core frame tool, the mode of vacuum suction need to be used to be fixed when lower core frame coordinates with core, and this structure is advantageous to vacuum suction, particularly prevents dropping and built on the sand for core.
Description
Technical field
Casting industry DISA production lines are the utility model is related to, it is especially a kind of to prevent core from falling for core frame under DISA lines
The air suction structure fallen.
Background technology
In existing casting industry, it is that can not produce casting that two pieces of templates, which are used only, in DISA line major part clamp product, need to be borrowed
Core and lower core frame tool is helped to aid in being produced.Core is moved after need to being put into lower core frame tool and core can be put into half
Sand mold in, then two halves sand mold carry out matched moulds, be moved to pouring position and poured into a mould, cooling complete it is offline after core it is automatic
Go to sticks and staves and come off, so as to form casting.Core is fixed when being put into lower core frame using suction hole vacuum suction mode, core connection position
It is smaller to put air-breathing area, easily causes core or unstable situation during placement, production line delay, batch production product can be caused
Size is bad and the wasting of resources.
Utility model content
The purpose of this utility model be to provide it is a kind of be used for the air suction structure that core frame prevents core from dropping under DISA lines, it
Can solve the problem that the deficiencies in the prior art, be it is a kind of it is simple in construction, easy to make, feasibility is high, avoids core from dropping and built on the sand
Structure.
The technical solution of the utility model：A kind of air suction structure for being used for core frame under DISA lines and preventing that core from dropping, including
Lower core frame and lower core frame locating piece, it is characterised in that the lower core frame that intercommunication is set gradually on lower core frame and lower core frame locating piece is inhaled
Stomata, lower core frame locating piece suction hole and lower core frame locating piece air-breathing groove, form vacuum suction structure.
The lower core frame locating piece air-breathing trough of the vacuum suction structure lives to be positioned over the core of lower core frame.
Lower core frame suction hole one end connection vacuum extractor, the one of the lower core frame locating piece suction hole of other end connection
End, the lower core frame locating piece air-breathing groove of other end connection of lower core frame locating piece suction hole, lower core frame locating piece air-breathing groove and core
Contact is adsorbed.
The lower core frame locating piece air-breathing groove is that the air-breathing area contacted with core is not less than 150mm2Cuboid knot
Structure.
The course of work of the present utility model：The structure is used when core is put into lower core frame.Lower core frame is put into core
When vacuum suction operation start, vacuum passes through lower core frame locating piece suction hole by lower core frame suction hole and reaches lower core during placing core
Frame locating piece air-breathing groove is so that core be fixed, and then mobile lower core frame, core is put into sand mold and discharges vacuum, then under
Core frame returns to initial position and carries out next round operation.After core is in sand mold, two halves sand mold carries out matched moulds, and then movement is entered
Row cast, offline core drops automatically after cooling, so as to produce casting.
Superiority of the present utility model：1st, the planform is simple, and ventilation is smooth, is easy to make, air-breathing slot structure is compared
Sucting hole structure area increase, be advantageous to the cooperation between core and lower core frame, at the same avoid core drop and core is put
The situation of shakiness is put, core also disposably can be positioned over lower core inframe by lower core personnel, avoid repeating to place.So not only mitigate
Personnel labor intensity, size caused by the wasting of resources caused by also avoiding production line delay and batch production are bad.2nd, this structure
Suitable for lower core frame tool, the mode of vacuum suction need to be used to be fixed when lower core frame coordinates with core, this structure is favourable
In vacuum suction, dropping and built on the sand for core is particularly prevented.
Brief description of the drawings
Fig. 1 is that a kind of structure for being used for the air suction structure that core frame prevents core from dropping under DISA lines is shown involved by the utility model
It is intended to.
Fig. 2 is Fig. 1 inframe enlarged drawings
In figure：1 is lower core frame locating piece air-breathing groove, and 2 be lower core frame locating piece suction hole, and 3 be lower core frame locating piece, and 4 are
Lower core frame suction hole, 5 be lower core frame.
Embodiment
Embodiment：It is a kind of to be used for the air suction structure (see Fig. 1, Fig. 2) that core frame prevents core from dropping under DISA lines, including lower core
Frame 5 and lower core frame locating piece 3, it is characterised in that the lower core frame that intercommunication is set gradually on lower core frame 5 and lower core frame locating piece 3 is inhaled
Stomata 4, lower core frame locating piece suction hole 2 and lower core frame locating piece air-breathing groove 1, form vacuum suction structure.
The lower core frame locating piece air-breathing groove 1 of the vacuum suction structure holds the core for being positioned over lower core frame 5.
The lower one end of core frame suction hole 4 connection vacuum extractor, the one of the lower core frame locating piece suction hole 2 of other end connection
End, the lower core frame locating piece air-breathing groove 1 of other end connection of lower core frame locating piece suction hole 2, lower core frame locating piece air-breathing groove 1 and type
Core contact is adsorbed.
The lower core frame locating piece air-breathing groove 1 is rectangular parallelepiped structure.
Lower core frame and lower core frame locating piece suction hole are in the exampleAir-breathing groove is long 20mm, wide 8.2mm, depth
2mm, R4mm, its air-breathing area is by 50.265mm2Increase as 150.265mm2, the increase of air-breathing area is original nearly 3 times, makes type
Core is more firm in lower core inframe, and is not easy to drop.
The lower core frame air suction structure application is good, and Expected Results is fully achieved.
