Description
Technical field
The present invention is a kind of injection forming mould, especially a kind of for being molded with the raw embryo for improving compactness, makes it
Mould suitable for making large-size target.
Background technology
Nesa coating tin indium oxide (Indium Tin Oxide), referred to as ITO, due to simultaneously have low electrical conductivity and
The characteristic of high transmission rate, has been widely used in electro-conductive glass, solar cell and the ELECTROMAGNETIC OBSCURANT glass of display at present
Etc. aspect.As display picture size tends to maximization, high-precision densification, film formation at low temp, low resistance characteristic, high transmission rate and film
The flatness on surface is the emphasis of ITO technologies development, and the Making programme of ITO target is divided into powder preparation, forming of green body, burning
The operations such as knot, processing, binding, wherein the method being molded includes compression moulding or slip casting, documents CN101890752 is public
Opened injection forming with mould carry out forming of green body, in production, forming of green body stage will be implanted into type due to both sides water suction
The moisture of the material in chamber is blotted, and biscuit is gradually molded by the both sides near water accepting layer, then slurry volume contraction, then gradual logical
Cross slurry to inject toward hole forming of green body area benefit slurry, untill the biscuit in die cavity is full of shaping area, under theoretical case, biscuit exists
The shaping speed on both sides is the same, and material can perfectly fill up whole cavity space, be in the middle of biscuit do not have it is with dissection, but,
Due to a variety of causes, the side of grouting port may first complete shaping, easily block slip casting passage, and grouting port it is relative one
Side then continues to eat slurry, and material cannot again be mended and come into when causing biscuit volume contraction, therefore, solve the problems, such as that this class shows
Obtain particularly important.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of injection forming mould, set by stainless steel layer
It is distributed the through hole of inequality and is provided with vavuum pump and solves in the middle of existing biscuit easily problem with dissection.
In order to solve the above problems, the invention provides a kind of injection forming mould, include mould, the mould it is interior
Portion is provided with forming of green body chamber, and the forming of green body chamber is disposed with interior water accepting layer, outer water accepting layer and stainless steel from the inside to surface
Layer, and the through hole of skewness is provided with the stainless steel layer, the stainless steel layer outside is surrounded with stainless steel casing, makes
Free area of space is reserved in the centre for obtaining stainless steel layer and stainless steel casing, is provided with very in the side of the stainless steel casing
Empty pump connecting hole is used for connecting vavuum pump, and the vavuum pump connecting hole is corresponding with grouting port.
Further improvement is that：Through hole with slip casting oral pore side be center of circle end, and circumferentially radian distribution in layer
On stainless steel layer, radius of a circle more large through-hole aggregation is closeer so that the close place water suction of through hole aggregation is faster, on same circumference
Through hole neighbor distance it is the same.
Further improvement is that：Upper and lower two stainless steel casings are fixed by connecting rod.
Further improvement is that：Resin or gypsum material are filled with the interior water accepting layer and outer water accepting layer.
The beneficial effects of the invention are as follows：The present invention is distributed not by being provided with outside outer water accepting layer multi-through hole but through hole
Uniform stainless steel layer, and an area of space for sky is provided with below stainless steel layer, it is true during whole slip casting
Empty pump is fast by vacuumize that moisture siphons away because the through hole for vacuumizing side is closeer all the time in operation, so the element of this side
Base can first be molded, other side（Injected hole side）Through hole is relatively dredged, the meeting aftershaping slowly of moisture loss, in the later stage of shaping, is led to
Cross during injected hole mends slurry, injected hole side will not be blocked, and it is very uniform that this allows for whole biscuit, is not in interlayer,
Simple structure of the present invention, it is easy to operate, substantially increase forming of green body quality.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Wherein：1- moulds, 2- forming of green body chamber, water accepting layer in 3-, the outer water accepting layers of 4-, 5- stainless steel layers, 6- through holes, 7- is not
Rust outer steel shell, 8- vavuum pump connecting holes, 9- connecting rods.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in figure 1, present embodiments providing a kind of injection forming mould, mould 1, the inside of the mould 1 are included
It is provided with forming of green body chamber 2, the forming of green body chamber 2 is disposed with interior water accepting layer 3, outer water accepting layer 4 and stainless from the inside to surface
Steel layer 5, and the through hole 6 of skewness is provided with the stainless steel layer 5, the outside of the stainless steel layer 5 is surrounded with stainless steel
Shell 7 so that free area of space is reserved in the centre of stainless steel layer 5 and stainless steel casing 7, in the stainless steel casing 7
Side is provided with vavuum pump connecting hole 8 for connecting vavuum pump, and the vavuum pump connecting hole is corresponding with grouting port.Through hole is noting
Slurry oral pore side is center of circle end, and circumferentially radian being distributed on stainless steel layer in layer, and radius of a circle is got over large through-hole and gathered
Collection is closeer so that the close place water suction of through hole aggregation is faster, and the through hole neighbor distance on same circumference is the same.Shown in upper and lower two
Stainless steel casing 7 is fixed by connecting rod 9.Resin or gypsum material are filled with the interior water accepting layer 3 and outer water accepting layer 4
Material.
The present invention is provided with multi-through hole but through hole stainless steel layer 5 pockety by the outside of outer water accepting layer 4, and
And it is provided with an area of space for sky below stainless steel layer 5, in whole slip casting process intermediate pump all the time in operation, by
It is closeer in the through hole for vacuumizing side, it is fast by vacuumize that moisture siphons away, so the biscuit of this side can first be molded, in addition one
Side through hole is relatively dredged, the meeting aftershaping slowly of moisture loss, in the later stage of shaping, during mending slurry by injected hole, injected hole one
Side will not be blocked, and it is very uniform that this allows for whole biscuit, is not in interlayer, simple structure of the present invention, it is easy to operate, carry significantly
Forming of green body quality high.
