Described rectangle external jacket is surrounded by two long-armed clamp bars and two galianconism fixture blocks; Two horizontal sides that long-armed clamp bar is not waited by length and the vertical edge that vertically connects two horizontal sides surround, and two horizontal sides lay respectively at the left and right side of vertical edge upper and lower end, and the shape of cross section of galianconism fixture block is I shape; Two long-armed clamp bars with longer horizontal sides and vertical edge respectively parallel connection surround rectangle, two U-shaped grooves of galianconism fixture block are connected in respectively the inner side of vertical edge in the longer horizontal sides of two long-armed clamp bars.
It is rectangular that the longer horizontal sides inner side of described long-armed clamp bar is connected with the triangle of evagination along its length, and the rectangular length of triangle is greater than the length of described rectangle ebonite piece.
The U-shaped bottom land limit of described galianconism fixture block offers the corresponding V-type groove corresponding with the rectangular position of described triangle, and the distance between two V-type groove bottom lands is less than the width of described rectangle ebonite piece.
Fastening by fishbolt and respective nut between the longer horizontal sides of a described long-armed clamp bar and the shorter horizontal sides of another long-armed clamp bar.
Between described galianconism fixture block length direction and long-armed clamp bar by through long-armed clamp bar vertical edge hold out against screw fastening in the two ends of described rectangle ebonite block length direction.
The outer wall of described soft mode cover has the shaping cover corresponding with board dimension, and the sidewall of shaping cover offers the through hole that runs through its thickness, to ensure linearity and the surface smoothness of sheet material.
The principle that the utility model can seal soft mode cover is as follows: the feature of utilizing rubber energy strain, rectangle ebonite piece being filled in the port of soft mode cover makes it produce strain, inwardly apply chucking power by rectangle external jacket in the surrounding in soft mode cover port outside again, make rectangle ebonite piece under the effect of external force, there is strain in a small amount, form reverse resistance, thereby the real soft mode cover of tightening seal port, when isostatic pressing, stop highly pressurised liquid to enter in soft mode cover, improve the acceptance rate of shaped article, solve current Powder Metallurgy Industry and produced the high problem of percent defective of medium-and-large-sized sheet material.

Detailed description of the invention
As shown in Figures 1 to 5, the utility model discloses a kind of static pressure compacting tool set that waits, for metallurgical powder compacting is produced to large-sized sheet material.This mould mainly comprises rectangle ebonite piece 1, soft mode cover 2, long-armed clamp bar 3 and galianconism fixture block 4.Two long-armed clamp bars 3 and two galianconism fixture blocks 4 surround rectangle external jacket.Two horizontal sides that long-armed clamp bar 3 is not waited by length and the vertical edge that vertically connects two horizontal sides surround, and two horizontal sides lay respectively at the left and right side of vertical edge upper and lower end.The shape of cross section of galianconism fixture block 4 is I shape.Two long-armed clamp bars 3 with longer horizontal sides and vertical edge respectively parallel connection surround rectangle, it is rectangular 7 that the long horizontal sides inner side of long-armed clamp bar 3 is connected with the triangle of evagination along its length, the length of triangle rectangular 7 is greater than the length of rectangle ebonite piece 1.The U-shaped groove of galianconism fixture block 4 upper and lower ends is connected in respectively the inner side of vertical edge in the longer horizontal sides of two long-armed clamp bars 3, the U-shaped bottom land limit of galianconism fixture block 4 offers the width that distance between the corresponding V-type groove corresponding with rectangular 7 positions of triangle 41, two V-type groove 41 bottom lands is less than rectangle ebonite piece 1.
Before isostatic pressing, first powder is packed in soft mode cover 2, then rectangle ebonite piece 1 is filled in the port of soft mode cover 2 and port part is placed in rectangle external jacket, then by fastening by fishbolt 5 and respective nut between the longer horizontal sides of a long-armed clamp bar 3 of rectangle external jacket and the shorter horizontal sides of another long-armed clamp bar 3, between the length direction of galianconism fixture block 4 and long-armed clamp bar 3 by the two ends that hold out against screw 6 and be anchored on rectangle ebonite piece 1 length direction through long-armed clamp bar 3 vertical edges.The size of rectangle ebonite piece 1 is determined according to the size of sheet material.
Fishbolt 5 and hold out against screw 6 and make rectangle ebonite piece 1 have strain in a small amount to form reverse resistance when fastening, thereby by real the openend tightening seal of soft mode cover 2.
In order to ensure linearity and the surface smoothness of sheet forming, port is sealed to real soft mode cover 2 and be placed in the shaping cover corresponding with board dimension 8, offer at the sidewall of shaping cover the through hole that runs through its thickness high pressure liquid physical efficiency is entered in it.
The principle that the utility model can seal soft mode cover is as follows: the feature of utilizing rubber energy strain, rectangle ebonite piece 1 being filled in the port of soft mode cover 2 makes it produce strain, inwardly apply chucking power by rectangle external jacket in the surrounding in the port outside of soft mode cover 2 again, make rectangle ebonite piece 1 under the effect of external force, there is strain in a small amount, form reverse resistance, thereby the port of the real soft mode cover 2 of tightening seal, when isostatic pressing, stop highly pressurised liquid to enter in soft mode cover 2, improve the acceptance rate of shaped article, solve current Powder Metallurgy Industry and produced the high problem of percent defective of big-and-middle-sized sheet material.
