The height of the lower mould is 9~11mm；
The upper die and lower die fasten to form edge thickness for 9~11mm, and center thickness is 4~8mm die cavity.
Preferably, the lower surface of the upper mould has decorative pattern.
Preferably, the adobe being made using the stamping forming mould of the powder for dry-press process, the upper table of adobe
Face has the cavity caved inward.
Preferably, the cross section of the cavity of the adobe is arc, i.e., the cavity of described adobe from edge to center gradually
Cave inward.
Preferably, the central concave depth of the cavity of the adobe is 3~5mm；
The thickness of the adobe is 9~11mm.
The stamping forming mould of the powder for dry-press process sets the upper mould of lower surface outwardly convex, so that
The die cavity that upper surface is inside concave surface is formed, is suppressed using the stamping forming mould of the powder for dry-press process
The upper surface of the adobe come has the cavity to lower recess, it can be seen from material mechanics principle, and stress disperses, and is not susceptible to drying
Cracking, reduction finished product loss, improves product quality.
The cavity of the adobe gradually caves inward from edge to center, so as to will focus on the stress at middle part to adobe
Surrounding is disperseed, and then adobe is not susceptible to season cracking, reduces finished product breakage rate.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
The stamping forming mould of powder for dry-press process of the present embodiment, as shown in Figure 1 and Figure 2, including the He of upper mould 1
Lower mould 2, the upper mould 1 and lower mould 2 fasten and form die cavity 3；
The lower surface outwardly convex of the upper mould 1；The upper surface of the die cavity 3 faces out for the following table with the upper mould 1
Raised corresponding concave surface.
The dry process for forming of architectural pottery is that the ceramic powder after grinding is poured into compacting tool set after non-slurry pelletizing
In, then adobe is pressed into by single lead screw ex truding briquetting machine.The upper and lower mould of existing compacting tool set is smooth, forms the mould of a cuboid
Chamber；Again because the ceramic powder grain shape that non-slurry pelletizing is formed is generally the centrum and cylinder that particle size differs, rather than biography
The mist projection granulating of system forms uniform spherical particles like that；So that to next adobe stress concentration is suppressed, easily occurring dry
Dry cracking, has a strong impact on product quality.
And the stamping forming mould of the powder for dry-press process sets the upper mould 1 of lower surface outwardly convex,
So as to form the die cavity 3 that upper surface is inside concave surface, using the stamping forming mould of the powder for dry-press process
The upper surface of the adobe 4 come is suppressed with the cavity 41 to lower recess, it can be seen from material mechanics principle, stress disperses, no
Easily occurs season cracking, reduction finished product loss improves product quality.
Preferably, the cross section of the upper mould 1 is arc, i.e., the lower surface of described upper mould 1 from edge to middle part gradually to
Outer lug；The upper surface of the die cavity 3 and the lower surface of the upper mould 1 accordingly gradually cave inward from edge to middle part.Shape
Into the die cavity 3 gradually caved inward from edge to center so that the adobe 4 suppressed will focus on middle part should
Power is scattered to surrounding, and then adobe 4 is not susceptible to season cracking, reduces finished product breakage rate.
Preferably, the outwardly convex depth of the upper mould 1 is 3~5mm, preferably 4.5mm；The height of the lower mould 2 is 9
~11mm, preferably 10mm；The upper mould 1 and lower mould 2, which are fastened, forms edge thickness for 9~11mm, and center thickness is 4~8mm
Die cavity 3.If the outwardly convex depth of the upper mould 1 is too small, the stress peptizaiton of adobe 4 being made is not obvious, and finished product is broken
Loss rate is high；If the outwardly convex depth of the upper mould 1 is too big, the thickness for the adobe 4 being made is too small, and intensity declines, easily hair
Raw fracture.
Preferably, the lower surface of the upper mould 1 has decorative pattern so that suppress come adobe 4 upper surface have it is rich
Rich colorful texture, expands the stamping forming mold use scope of powder for dry-press process.
Preferably, the adobe being made using the stamping forming mould of the powder for dry-press process, as shown in figure 3,
The upper surface of adobe 4 has the cavity 41 caved inward, and it can be seen from material mechanics principle, the cavity 41 makes dry-press process
The stress of the adobe 4 disperses, and is not susceptible to season cracking, improves product quality.
Preferably, the cross section of the cavity 41 of the adobe 4 is arc, i.e., the cavity 41 of described adobe 4 is from edge in
The heart gradually caves inward, so that the stress that will focus on middle part disperses to the surrounding of adobe 4, and then makes adobe 4 be not susceptible to do
Dry cracking, reduces finished product breakage rate.
Preferably, the central concave depth of the cavity 41 of the adobe 4 is 3~5mm, preferably 4.5mm；The adobe 4
Thickness be 9~11mm, preferably 10mm.If the central concave depth is too small, stress peptizaiton is not obvious, and finished product is broken
Loss rate is high；If the central concave depth is too big, the thickness of the adobe layer 11 is too small, and intensity declines, and is easily broken.
The stamping forming mould of powder for dry-press process of the present embodiment has the advantages that：1. following table is set
Towards the upper mould 1 of outer lug, thus formed upper surface be inside concave surface the die cavity 3, using it is described be used for dry method into
The stamping forming mould of powder of type suppresses the upper surface of the adobe 4 come with the cavity 41 to lower recess, according to material power
Learn principle to understand, stress disperses, be not susceptible to season cracking, reduction finished product loss improves product quality；2. the mould formed
Chamber 3 gradually caves inward from edge to center, so that the stress that the adobe 4 suppressed will focus on middle part divides to surrounding
Dissipate, and then adobe 4 is not susceptible to season cracking, reduce finished product breakage rate；3. described in the lower surface of upper mould 1 there is decorative pattern, from
And make the upper surface for suppressing the adobe 4 come that there is colourful texture, expand the powder punching press for dry-press process
The mold use scope of shaping.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to the utility model protection domain can not be construed in any way.Based on explanation herein,
