Abstract
The present invention discloses a kind of subregion isostatic pressing mold, include core rod and be used to fix the die holder of core rod, the type face of core rod is compounded with film, some oil pockets are formed between film and core rod, all oil pockets of core rod press region division, oil pocket connection in the same area, the oil pocket closing isolation of different zones, the first through hole of connection regional oil pocket is offered in the matrix of core rod respectively, also the second through hole of each first through hole of correspondence, connecting pipe between first through hole and the second through hole are offered in die holder respectively.Oil pocket in so each region can all use single oil circuit fuel feeding, and the oil pressure of separately adjustable each road binders, for burning till, scale error is big, cloth density difference is big, can be by adjusting the oil pressure of corresponding region, to ensure that each areal concentration is uniform during pressing unfired brick as much as possible, scale error is burnt till in reduction.
Description
Technical field
The present invention relates to the mould technical field of Ceramic Tiles, specifically related to a kind of isostatic pressed of separated regions control into
Pattern has.
Background technology
Ceramic brick powder lot shaping is using the traditional approach that isostatic pressing mold is that current ceramic tile production is commonly used.Mesh
Before, after the base substrate of Ceramic Tiles isostatic pressing burns till through alternating temperature, single-chamber part burn till scale error and multi-cavity part burn till size
Error, usually using isostatic pressed area, control firing atmosphere for pad being padded on regulation cloth error, mould, increasing mould etc.
Mode is solved.
However, traditional Ceramic Tiles are burnt till, scale error regulation is time-consuming more long, and adjustable range is restricted, and causes Ceramic Tiles
Burn till scale error, the mass defect such as single-chamber part concentric reducer, scale error between the scale error of closing waist and multi-cavity part.Ceramics
Brick has edging and the not Ceramic Tiles of edging.Edging difference in size does not directly affect the quality of product；The ceramic dimension difference shadow of edging
Ring edging amount and edging quality.
Isostatic pressing mold is the adhesive sheet in the forming surface of core rod, and separates between forming surface and film and have
Filling hydraulic oil in some interconnected oil pockets, oil pocket.During pressing unfired brick, using law of connected vessels, the film of each oil pocket
Pressure it is equal, realize adobe even density everywhere with this, scale error is burnt till in reduction.But this static-pressure forming mould
Tool is typically all confined to the little situation of cloth uniformity regional error, if error is excessive, is still difficult to ensure that
Each areal concentration is uniform during pressing unfired brick.Reason is the impossible excessive deformation of film, and the region serious for lacking powder, is to be difficult to press
To the density as other regions.Therefore existing Ceramic Tiles isostatic pressing is not still good enough in the presence of scale error control is burnt till
Problem.
The content of the invention
The technical problem to be solved in the present invention is to provide and a kind of controls Ceramic Tiles to burn till scale error by subregion
Mould.
To solve the technical scheme that above-mentioned technical problem is used：A kind of subregion isostatic pressing mold, includes core rod
And it is used to fix the die holder of core rod, the type face of core rod is compounded with film, some oil pockets is formed between film and core rod, and it is special
Levy and be：All oil pockets of the core rod press region division, in the same area oil pocket connection, different zones oil pocket closing every
From, the first through hole of connection regional oil pocket is offered in the matrix of core rod respectively, die holder is interior also to offer correspondence often respectively
Second through hole of one first through hole, connecting pipe between first through hole and the second through hole.
On the basis of the above, connected using snap joint between the pipeline and first through hole and the second through hole.
The beneficial effect brought using the present invention：Oil pocket in the forming surface of core rod is divided into some regions by the present invention,
Oil pocket connection in the same area, the oil pocket closing isolation of different zones.Oil pocket in so each region all can be using independent
Oil circuit fuel feeding, and separately adjustable each road binders oil pressure, for burning till, scale error is big, cloth density difference is big, just
Can be by adjusting the oil pressure of corresponding region, to ensure that each areal concentration is uniform during pressing unfired brick as much as possible, size is burnt till in reduction
Error.
Brief description of the drawings
Fig. 1 is the structural representation of core rod in the present invention；
Fig. 2 is the structural representation of isostatic pressing mold of the present invention.
Specific embodiment
As shown in Figure 1, 2, a kind of subregion isostatic pressing mold, includes core rod 1 and is used to fix the die holder of core rod 1
2, the type face of core rod 1 is compounded with film 3, and some oil pockets 4 are formed between film 3 and core rod 1.In the present invention, the core rod 1
All oil pockets 4 press region division, such as the multi-cavity mould of the three sets core rods of installation in Fig. 1,2, each core rod divide A, B area
Domain, also can more be subdivided into multiple regions certainly, and this ought set in response to needs.Oil pocket 4 in the same area is connected, different zones
The closing isolation of oil pocket 4, the first through hole 5 of connection regional oil pocket 4 is offered in the matrix of core rod 1 respectively, in die holder 2 also
The second through hole 6 of each first through hole 5 of correspondence, connecting pipe 7 between the through hole 6 of first through hole 5 and second are offered respectively.This
Sample, subregion isostatic pressing mold of the present invention can be using the hydraulic system fuel feeding with multichannel, 4 points of the oil pocket in each region
It is not connected with oil circuit all the way, so oil pressure per road binders road just can be set as separately adjustable, and for burning till, scale error is big, cloth
Material density difference is big, so that it may by adjusting the oil pressure of corresponding region, to ensure each areal concentration during pressing unfired brick as much as possible
Uniformly, reduce and burn till scale error.
In order to realize the Fast Installation of subregion isostatic pressing mold, the pipeline 7 and the through hole 6 of first through hole 5 and second
Between using snap joint connect.
Claims (2)
1. a kind of subregion isostatic pressing mold, includes core rod and is used to fix the die holder of core rod, and the type face of core rod is combined
