Detailed description of the invention
It is described with reference to the representative embodiment of the present invention.
Referring to figs. 1 through Fig. 2, the mould with reinforcing plate structure of the present invention, including: core box 10；It is fixed on the end of core box 10
Reinforcing plate structure 20 on plate 11, the volume of reinforcing plate structure 20 can change along the direction R being parallel to base plate 11.Set on upper soft shell 24
It is equipped with the unidirectional air valve 31 connecting air bag 30.The present invention fixes reinforcing plate structure 20, reinforcing plate structure on the base plate 11 of core box 10
The volume of 20 can change along the direction R being parallel to base plate 11, and when casting sand core, the volume of reinforcing plate structure 20 becomes big to meet
Core casting requirement, when core has cast molding, the volume of reinforcing plate structure 20 diminishes so that core is smooth from core box 10
The demoulding, thus when solving employing tradition core box making core, gusset size does not meets size tolerance requirements and core is difficult to
The problems such as the demoulding.The unidirectional air valve 31 arranged on upper soft shell 24 is for inflation in air bag 30 or by the gas in air bag 30
Release.
Referring to figs. 1 through Fig. 3, reinforcing plate structure 20 includes: the lower duricrust 21 being fixed on base plate 11；It is perpendicular to lower duricrust 21 also
The front duricrust 22 that can slide in opposite direction relative to lower duricrust 21 and rear duricrust 23；And connect lower duricrust 21, front duricrust 22
Upper soft shell 24, left soft shell 25 and right soft shell 26 with rear duricrust 23；Be contained in by lower duricrust 21, front duricrust 22, rear duricrust 23, on
The air bag 30 sealed in space that soft shell 24, left soft shell 25 and right soft shell 26 surround.Air bag 30 is by glue and reinforcing plate structure 20
The inwall of shell is bonding.Gas expansion air bag 30 during inflation so that air bag 30 promotes front duricrust 22 and rear duricrust 23 sliding along direction R
Dynamic, thus increase the volume (with reference to Fig. 4) of reinforcing plate structure 20.During venting, connecting key 40 pulls front duricrust 22 and rear duricrust 23 to contract
Return, thus reduce the volume (with reference to Fig. 5) of reinforcing plate structure 20.
With reference to Fig. 3, it is connected by telescopic connecting key 40 between front duricrust 22 with rear duricrust 23.Connecting key 40 includes many
Individual, multiple connecting keys 40 are configured to 4 × 6 array formats.The connecting key of array format arrangement contributes to front duricrust 22 and rear duricrust
23 all the time parallel synchronous move, do not have deflection.Of course it is to be understood that the quantity of connecting key and arrangement form can be according to realities
Border demand is arbitrarily arranged, and the present invention is not limited to this.
With reference to Fig. 3, connecting key 40 includes being arranged between front duricrust 22 and rear duricrust 23 and front duricrust 22 He of fixing connection
The spring 41 of rear duricrust 23 and steel wire rope 42, the length when length of steel wire rope 42 is not stretched more than spring 41, thus ensure
When steel wire rope 42 stretches and tightens, spring 41 is stretched loading.Steel wire rope 42 extends through spring 41 and by bolt 43
It is fixed to front duricrust 22 and rear duricrust 23.In the pit in the outside that the nut of bolt 43 is contained in front duricrust 22 and rear duricrust 23,
Being filled with implant 44 in pit, the surface of implant 44 flushes with the outer surface of front duricrust 22 and rear duricrust 23.Outside flushing
Surface is conducive to the core surfacing of casting, has good presentation quality.Air bag 30 is provided with and passes for connecting key 40
Cavity 32.Preferably, the length of steel wire rope 42 is equal sized with the inner chamber of core to be cast, casts out with guarantee
Core meets preliminary dimension requirement.The effect of steel wire rope 42 is when air bag 30 inflation, limit front duricrust 22 and rear firmly
The distance that shell 23 moves meets the preliminary dimension requirement of core, and the effect of spring 41 is when air bag 30 deflation, energy
Enough front duricrust 22 and rear duricrust 23 are retracted so that the volume of reinforcing plate structure diminishes, consequently facilitating the core demoulding.
With reference to Fig. 1, core box 10 also includes being arranged on base plate 11 and around the side plate 12 of reinforcing plate structure 20, and is arranged on
The sleeping material 13 in core box mouth location on side plate 12.Core box mouth location is sleeping expects that 13 are connected with reinforcing plate structure 20 and are used for determining reinforcing plate structure
The position of 20.The effect of the sleeping material 13 in core box mouth location also resides in, when current duricrust 22 and rear duricrust 23 move, it is possible to auxiliary gusset
Structure 20 is kept upright attitude, it is ensured that the position of reinforcing plate structure 20 is correct.
Preferably, lower duricrust 21, front duricrust 22 and rear duricrust 23 are made up of hard PVC material, and its thickness is 6～15mm；
Upper soft shell 24, left soft shell 25 and right soft shell 26 are made up of flexible plastic or silica gel.Upper soft shell 24, left soft shell 25 and right soft shell 26
Flexible nature, on the one hand ensures the air-tightness within reinforcing plate structure 20, on the other hand ensures that front duricrust 22 and rear duricrust 23 can
Move freely.Of course it is to be understood that the lower duricrust 21 of the present invention, front duricrust 22, rear duricrust 23, upper soft shell 24, left soft shell 25 and
Right soft shell 26 can be made up of other suitable materials, and the present invention is not limited to this.
The mold use process example ground of the present invention is: first assemble reinforcing plate structure 20 before use, then by lower duricrust
21 fix with bolt with the base plate 11 of core box, are filled with 0.5～0.8MPa by unidirectional air valve 31 during use in air bag 30
Compressed air, makes reinforcing plate structure entirety prop up molding, the steel wire rope 42 that the maximum swelling thickness of gusset is limited in connecting key
Length (with reference to Fig. 4), equal to the dimensional requirement of foundry goods, after sand mold hardens, is put air bag 30 by unidirectional air valve 31
Gas, makes the shell of reinforcing plate structure 20 be contracted to the size (with reference to Fig. 5) less than core inner chamber, it is achieved the smooth demoulding of core.
The reinforcing plate structure of the present invention can be repeated several times use, and is hardly damaged.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
