According to another form of implementation of the present invention, each end face of dividing plate has some bore holes, can hold location and anchor and pass through.

According to also belonging to another form of implementation of the present invention, the groove of opening between dividing plate at its end by supporting plate on the end face dividing plate or edge strip sealing, supporting plate or edge strip and terminal central dividing plate (its length is slightly less than the length of end face dividing plate) stay the gap of a thin slice size, to limit the peripheral output magazine of honeycomb structure.

With the example explanation, can understand characteristic of the present invention and advantage better with reference to the accompanying drawings, in the accompanying drawings:

-Fig. 1 is the partial cut pictorial perspective view according to pressing unit form of implementation of the present invention;

-Fig. 2 and Fig. 3 are two local figure, and the upper and lower of Fig. 1 device is shown respectively, show and allow the output that ceramic mud passes through and enter the hole;

-Fig. 4 is the fragmentary, perspective view of a single dividing plate of the device in the relevant earlier figures;

-Fig. 5 is the similar figure of Fig. 4, shows the butt joint of two similar dividing plates;

-Fig. 6 is the sectional view along VI among Fig. 5-VI face.

According to structure selected and that illustrate, apparatus of the present invention are made of one group of dividing plate, and every dividing plate all is general parallelepiped shape, this group dividing plate comprises dividing plate 10, dividing plate 10 is all similar each other, and some dividing plates place the side of other dividing plates, between end face dividing plate 11 and 12.

These dividing plate combination backs form the P plate, see it is a rectangle or square by orthographic plan, the joint of this group dividing plate, can realize with two pins that do not show, the bore hole 13 of two pins by opening at each end face of described dividing plate, make the Yong ， And of dividing plate location and also have the butt joint and the fastening piece of these dividing plates.

Each dividing plate 10 and each end face dividing plate 11 and 12 all have a rectangular cross section ， And and a upper surface 15 are arranged, a lower surface 16 and two vertical surfaces 17 and 18.

On each vertical surface 17,18 of central partition plate and on the interior vertical surface in end face dividing plate 11 and 12, have one group of groove 20, for example, by the groove that milling is made, each groove 20 has a wedged bottom 22 between two sides 21 perpendicular to face 17,18, this end, tilt with respect to face 17,18, groove 20 degree of depth differ, and full depth is at upper surface 15, and minimum is a null value, certain place a bit on lower surface, to the distance of lower surface be the place of d.

On every dividing plate 10, the groove 20 of the one side of face 17,18 and the groove of another side 20 the same ground uniform distribution are arranged relatively.Between the bottom of two relative grooves 20 on the surface 15, a fillet 23 is arranged.The groove 20 of adjacent dividing plate is corresponding mutually.

On a vertical surface of dividing plate, on this routine face 17,, make a recess 25 at the lower part of every dividing plate 10, become a plane 26, be that face 17 is parallel therewith for e ， And with respect to the face 17 indentation degree of depth.This recess starting point is the local (see figure 6) of D in lower surface 16 distances to dividing plate, and D is greater than d.

In addition, except the lower surface 16(of every dividing plate end face dividing plate and end face groove) on, along the symmetrical vertical surface of each groove 20, open a groove 28, its width L equals e, and its difference of altitude seldom equals D(Fig. 4,5 and 6) so that stride the repeatedly bottom of this groove 20.

Therefore, assembling upper spacer 10 between end face dividing plate 11 and 12, when forming the P plate, just (this surperficial Shi Tong Guo And is put several surperficial 15 and formed) monoblock of formation in can the one side in multiaspect, some perforates 30 have just appearred on this piece face, each hole 30 is to form (Fig. 3) by two grooves 20 that make up two adjacent dividing plates, and have between groove 31(groove and the groove vertical mutually chiseling one on another surface (and put surface 16)) net, this net is formed by those grooves 28 and recess 25, under latter event, the line of rabbet joint is (Fig. 6) that is made of adjacent planar 26 and adjacent surface 18.

End face dividing plate 11 and 12 sides with respect to lower surface 16 are compared with common dividing plate 10, and an excessive portion is arranged, and it is equivalent to the thickness of a line of rabbet joint 31 around the honeycomb structure.

When adding a slice edge strip on the dividing plate of assembling (not showing), by recess 25 formed end of slot, peripheral line of rabbet joint 31a sometimes may be thicker than the line of rabbet joint 31 of net by a peripheral line of rabbet joint 31a sealing.

Equally,, have a bigger thickness, be equivalent to the covering on every side of honeycomb structure at the groove 31b that opens against end face dividing plate 11 and 12.

Communicate between hole 30 and the groove 31.Like this, with arbitrary proper device ceramic mud is pushed away via hole 30, the square grid by the line of rabbet joint 31 is pushed then, just forms the honeycomb structure of making every effort to obtain.

Apparatus of the present invention are particularly suitable for suppressing high temperature resistant and parts high pressure, for example, the filter that liquid metals is used, these elements are made with refractory material in the case.

Certainly, the invention is not restricted to the described and represented enforcement version that goes out, it can have various modification, and these variation device are easy to be the know-how librarian use, but do not deviate from spirit of the present invention. Therefore, easily that the groove vegetables are logical behind the block die body P of dismounting when one or several lines of rabbet joint 31 stop up, and do not damage the danger of groove, and even after super-dry, the material that enters in the groove is very hard, situation also is like this.
