Description

Cladding pottery plate extrusion die

Technical field

Utility model is the improvement to curtain wall terra-cotta moulding extrusion die, but relates in particular to a kind of independent regulation cross section each point mud volume, and the moulding mud extraction is stable, extrudes the pottery board size accurately and do not allow yielding cladding pottery plate extrusion die.

Background technology

The pottery plate is as a kind of novel cladding installation curtain wall decoration material, and pottery plate not only size is relatively large, and plate face change in size is bigger, and mostly again is the asymmetric hollow structure in the left and right sides (wall thickness 6-15mm), and prior art adopts the wet method extrusion molding to produce basically.Existing extrusion molding mould adopts the tradition bricks die structure (Fig. 1,2,3) of riving, and the front end squeezing mud tube 1 be provided with the adjusting section 3 in adjustable mud extraction cross section and the embedded molding port mould 4 of front end, and the mud extraction adjusting range is whole structure 2 of length and width degree.The main deficiency of this structure mold is.

1, because mud extraction is adjusted to whole structure of length and width degree, regulating mud extraction can only whole adjusting, can not local modulation; Degree of regulation is not high, causes mud volume unstable easily, causes that asymmetric both sides are dry shrinks different and deform; And this distortion increases and increases along with pottery plate Aspect Ratio; Length: width ratio is greater than 2.5 o'clock, and the distortion probability reaches 10～40%, and for example to be the 1200*300mm products will exceed 30% than the deformation extent percent defective of 600*300mm products to sectional dimension.And the pottery plate adopts cladding mounting means, and template is a dissymmetrical structure, is connected between plate and the plate and belongs to chelated forms, and this mounting means requires high to the straight degree of pottery edges of boards, and the distortion probability increases and causes product percent of pass low.Secondly, whole adjusting of mud extraction, also inhomogeneous because of pug density soft or hard, make that mud extraction density in mud extraction cross section is inconsistent, also can influence extrusion molding pottery plate quality.

2, extrude pug and squeeze mud tube (width 450mm) through broad; Directly extrude, also can cause that easily mud extraction is not smooth because of the mud extraction abrupt change of cross-section by narrow mud mouth (width has only a 200-300mm usually) mouthful mould; Cause the left, center, right mud volume unbalanced, can cause moulding not accurate equally.

3, institute of pottery plate producer uses the make-up machine great majority to be the import make-up machine; Extruding force is bigger; And pottery plate width is less, the mud extraction abrupt change of cross-section also make make-up machine in the running pug at the mould mouth backflow phenomenon is arranged, cause that extruded product left and right sides density is inconsistent to deform when dry.

4, an existing mouthful of mould part is to be embedded into adjustable mud extraction cross section to regulate section, and its matching is strong, changes the extrusion neck ring mold exit width, and the adjusting section in adjustable mud extraction cross section just needs to change, and has increased die cost.

5, for guaranteeing moulding pug one typing length, mouthful mould thicker relatively (60-80mm), and a mouthful mold materials is high-grade material, increases mouthful mould thickness to make die cost higher, but also increased manufacture difficulty.

Above-mentioned deficiency perplexs curtain wall terra-cotta high-quality, High-efficient Production for a long time.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, but a kind of cross section each point mud volume independent regulation is provided, and the moulding mud extraction is stable, extrudes the pottery board size accurately and do not allow yielding cladding pottery plate extrusion die.

The utility model purpose realizes that mainly improving one is to change whole adjustable plate of length and width degree into the segmentation regulating block, regulates mud volume respectively thereby be convenient to each mud extraction point of cross section; The 2nd, increase by a crowded mud cross section between crowded mud tube and the adjustable mud extraction cross section adjusting section and satisfy the crowded mud changeover portion of the little taper of convergent; Make and extrude pug one gradual change (cross section reduces) extrusion is arranged; Thereby stablize a mouthful mould mud volume, overcome the deficiency of prior art, realize the utility model purpose.Specifically; The cladding pottery plate of utility model extrusion die; Comprise the adjustable mud extraction cross section adjusting section and the end face molding port mould that squeeze mud tube and front end; It is characterized in that adjustable mud extraction cross section regulates section and go up the radial expansion adjustable plate, width face one side at least is made up of a plurality of independent regulation pieces, adjustable mud extraction cross section regulate section and crowded mud tube between have the gradually little taper of crowded mud bore to squeeze the mud changeover portion.

The independent regulation piece is to regulate the each point mud volume separately with whole adjustable plate main distinction of former length and width degree, realizes the segmented adjusting, makes it to reach the best and extrudes state, and it is consistent to satisfy each position density of shaped article, guarantees Forming Quality.Width is thin more in theory, and it is good more to regulate accuracy, but objectively is difficult to accomplish also do not need mm dimension level, and according to test, independent adjustable width can satisfy with 10-20mm.Width face up-down adjustment can be to change the polylith combination simultaneously into, also can be that one side makes the polylith combining structure into; Another side still keeps en-block construction; False front for example can reduce pottery plate surface because of the trace that adds lustre to of slit rust aquatic products between regulating block, if regulating block adopts stainless steel material; Or the precision machining gap is minimum, also can be that the two sides is the fritter combining form.

Increasing and squeeze the crowded mud changeover portion of the gradually little taper of mud bore, mainly is to make extrusion molding squeeze the mud tube by the heavy in section to form gradual change extruding transition to small bore molding port mould, guarantees that mud extraction is smooth and easy, and it is balanced more to help the left, center, right mud volume, satisfies the requirement of cladding pottery plate straight flange.Test shows that conical section length is comparatively suitable with 35-55mm, too short then basic not effect, and long do not have this necessity yet.The tapering transition section is squeezed mud bore cross sectional shape, a kind ofly is preferably similar with mouthful mold forming shape, for example extrudes the dull and stereotyped rectangle that is, helps more guaranteeing that the mud volume total cross-section is balanced.

Each mud extraction point is not the point on the ordinary meaning, and is meant a smaller length, for example 10-20mm.

In addition, owing to increased crowded mud changeover portion, make the mud extraction land move forward in crowded mud tube mud extraction direction; Thereby not only can attenuate mouth mold thickness; Be thinned to 45 ± 5 mm, and need not adopt damascene structures, practiced thrift expensive mouth mold materials and processing charges greatly.

The cladding pottery plate of utility model extrusion die is with respect to prior art, owing to change the whole piece adjustable plate into the segmental structure regulative mode; Can make mud extraction regulate more accurately refinement to the mud extraction local modulation, it be consistent to reach each position density of shaped article; The cross section mud extraction is even, has not only reduced extrusion deformation, and wet base density is consistent; Shrink unanimity when dry, also be difficult for producing dry distortion; Increase taper and extrude changeover portion, make that to extrude mudflow steady, the cross section mud volume is balanced, the straight degree of the edges of boards of guaranteeing to make pottery.Improved the qualification rate of extruded product thus greatly, qualification rate improves about 20～50%.This structure simultaneously, mouthful mould thickness of having gone back attenuate can keep not increasing die cost.Besides, aforementioned mould structure improves, and has also improved adjustable mud extraction cross section and has regulated section and the compatibility that changes mouthful mould, and for example a mouthful mould is extruded width dimensions and changed in 50mm, can with one overlap adjustable mud extraction cross section the adjusting section, also reduce the Mold Making cost.The utility model mould can be used for the extrusion molding of various routines or special-shaped pottery plate.

Below in conjunction with two exemplary embodiments; Utility model essence is further understood in exemplary illustration and help; But the embodiment detail only is in order utility model to be described, not to be represented utility model design whole technical schemes down, therefore should not be construed as the total technical scheme of utility model to be limited; Some are In the view of the technical staff; The unsubstantiality that does not depart from utility model design increases and/or changes, and simple the change or replacement of technical characterictic to have same or similar technique effect for example all truely used novel protected scope.
