Description
Technical field
Mold the present invention relates to casting industry more particularly to the mold with reinforcing plate structure.
Background technology
There is die cast industry, for the structure design of core box, for sand core is enable smoothly to be demoulded when hardening molding, core box edge
The number of unmolulding directions design pattern draft of mold, but for some core boxes with large thin-wall reinforcing plate structure, when the length of gusset
It is oblique to reinforcing plate structure design draft when thickness is less than 60mm more than 2000mm, and draft can tiltedly lead to the variation of gusset size,
Since gusset size is larger, final overall dimensions will be unable to the tolerance for meeting client after increasing draft tiltedly.And it uses and divides mould
Method, mould material will be very scrappy, can also make mold body intensity insufficient, it is difficult to meet batch production.

Specific embodiment
It is described with reference to the representative embodiment of the present invention.
Referring to figs. 1 to Fig. 2, the mold with reinforcing plate structure of the invention, including：Core box 10；It is fixed on the bottom of core box 10
Reinforcing plate structure 20 on plate 11, the volume of reinforcing plate structure 20 can change along the direction R for being parallel to bottom plate 11.It is set on upper soft shell 24
It is equipped with the unidirectional air valve 31 of connection air bag 30.The present invention fixes reinforcing plate structure 20, reinforcing plate structure on the bottom plate 11 of core box 10
20 volume can change along the direction R for being parallel to bottom plate 11, and in casting sand core, the volume of reinforcing plate structure 20 becomes larger to meet
Sand core casting requirement, when sand core casts completion molding, the volume of reinforcing plate structure 20 becomes smaller in order to which sand core is smooth from core box 10
Demoulding, when making sand core using traditional core box so as to solve, gusset size does not meet size tolerance requirements and sand core is difficult to
The problems such as demoulding.The unidirectional air valve 31 set on upper soft shell 24 is used for into air bag 30 inflation or by the gas in air bag 30
It releases.
Referring to figs. 1 to Fig. 3, reinforcing plate structure 20 includes：The lower hard shell 21 being fixed on bottom plate 11；Perpendicular to lower hard shell 21 simultaneously
It can be relative to the preceding hard shell 22 and rear hard shell 23 that lower hard shell 21 slides in opposite direction；And connection lower hard shell 21, preceding hard shell 22
With the upper soft shell 24, left soft shell 25 and right soft shell 26 of rear hard shell 23；Be contained in by lower hard shell 21, preceding hard shell 22, rear hard shell 23, on
Air bag 30 in the sealing space that soft shell 24, left soft shell 25 and right soft shell 26 surround.Air bag 30 passes through glue and reinforcing plate structure 20
The inner wall bonding of shell.Gas expansion air bag 30 during inflation so that air bag 30 pushes preceding hard shell 22 and rear hard shell 23 to be slided along direction R
It is dynamic, so as to increase the volume of reinforcing plate structure 20 (with reference to Fig. 4).During deflation, connecting key 40 pulls preceding hard shell 22 and rear hard shell 23 to contract
It returns, so as to reduce the volume of reinforcing plate structure 20 (with reference to Fig. 5).
With reference to Fig. 3, connected between preceding hard shell 22 and rear hard shell 23 by telescopic connecting key 40.Connecting key 40 includes more
A, multiple connecting keys 40 are configured to 4 × 6 array formats.The connecting key of array format arrangement contributes to preceding hard shell 22 and rear hard shell
23 parallel synchronous movements always, are not in deflection.Of course it is to be understood that the quantity and arrangement form of connecting key can be according to realities
Border demand is arbitrarily set, and the present invention is not limited to this.
With reference to Fig. 3, connecting key 40 includes 22 He of hard shell before being arranged between preceding hard shell 22 and rear hard shell 23 and being fixedly connected
The spring 41 of hard shell 23 and steel wire rope 42 afterwards, the length of steel wire rope 42 is more than length when spring 41 is not stretched, so as to ensure
Spring 41 is stretched loading when steel wire rope 42, which stretches, to be tightened.Steel wire rope 42 extends across spring 41 and by bolt 43
It is fixed to preceding hard shell 22 and rear hard shell 23.The nut of bolt 43 is contained in the pit in the outside of preceding hard shell 22 and rear hard shell 23,
Filled with filler 44 in pit, the surface of filler 44 is flushed with the outer surface of preceding hard shell 22 and rear hard shell 23.What is flushed is outer
Surface is conducive to the sand core surfacing of casting, has good presentation quality.It is provided in air bag 30 and is passed through for connecting key 40
Cavity 32.Preferably, the length of steel wire rope 42 and the inner cavity for the sand core to be cast is equal sized, to ensure what is cast out
Sand core meets preliminary dimension requirement.The effect of steel wire rope 42 is when 30 inflation of air bag, hard shell 22 and rear hard before limitation
The distance that shell 23 moves meets the preliminary dimension requirement of sand core, and the effect of spring 41 is when 30 deflation of air bag, energy
It is enough to retract preceding hard shell 22 and rear hard shell 23 so that the volume of reinforcing plate structure becomes smaller, consequently facilitating sand core demoulds.
With reference to Fig. 1, core box 10, which further includes, to be arranged on bottom plate 11 and surrounds the side plate 12 of reinforcing plate structure 20 and be arranged on
The sleeping material 13 of core box mouth positioning on side plate 12.The sleeping material 13 of core box mouth positioning is connect with reinforcing plate structure 20 and for determining reinforcing plate structure
20 position.The effect of the sleeping material 13 of core box mouth positioning also resides in, and when current hard shell 22 and rear hard shell 23 move, can assist gusset
Structure 20 is kept upright posture, ensures that the position of reinforcing plate structure 20 is correct.
Preferably, lower hard shell 21, preceding hard shell 22 and rear hard shell 23 are made of hard PVC material, and thickness is 6~15mm；
Upper soft shell 24, left soft shell 25 and right soft shell 26 are made 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 inside reinforcing plate structure 20, on the other hand ensures that preceding hard shell 22 and rear hard shell 23 can
It moves freely.Of course it is to be understood that the lower hard shell 21 of the present invention, preceding hard shell 22, rear hard shell 23, upper soft shell 24,25 and of left soft shell
Right soft shell 26 can be made of other suitable materials, and the present invention is not limited to this.
It is the use process example of the mold of the present invention：Reinforcing plate structure 20 is first assembled using preceding, then by lower hard shell
21 are fixed with the bottom plate 11 of core box with bolt, are filled with 0.5~0.8MPa's into air bag 30 by unidirectional air valve 31 during use
Compressed air, makes reinforcing plate structure integrally prop up molding, and the maximum swelling thickness of gusset is limited to the steel wire rope 42 in connecting key
Length (with reference to Fig. 4) equal to the size requirement of casting, after sand mold hardening, puts air bag 30 by unidirectional air valve 31
Gas makes the shell of reinforcing plate structure 20 be contracted to size (with reference to Fig. 5) less than sand core inner cavity, realizes the smooth demoulding of sand core.
The reinforcing plate structure of the present invention can be repeated several times use, and be hardly damaged.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification for all within the spirits and principles of the present invention, being made,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
