Description
Technical Field
The utility model relates to a cold isostatic compaction field, in particular to with ceramic powder with mould that wet pocket formula cold isostatic compaction technology pressed into solid stick of pottery.
Background
The production history of the ceramic tube in China is only 20 years, hot-press casting molding is used as a main production process for many years, and with the development of the technology, the cold isostatic pressing technology is widely applied to the production of ceramic blanks. When the ceramic solid rod is produced by the cold isostatic pressing process, the outer elastic die can be compressed in the axial direction and the longitudinal direction when being pressed, and the compression in the longitudinal direction is easy to cause the breakage of the solid rod, so that the production difficulty is increased.
Disclosure of Invention
To the above-mentioned current problem, the utility model provides a wet bag formula isostatic compaction mould of solid stick, the utility model is suitable for a preparation of wet bag formula isostatic compaction pottery stick body utilizes the fracture of the body that this mould suppressed out, and easy operation can satisfy the requirement of large-scale production.
In order to achieve the above purpose, the utility model adopts the following scheme:
a solid rod wet bag type equal static pressure forming die comprises an outer elastic die, a porous outer supporting tube arranged outside the outer elastic die and metal plugs arranged at two ends of the outer elastic die; an internal thread elastic mold holding inclined plane is arranged at the groove of the metal plug; external threads are arranged at two ends of the porous outer supporting pipe and are tightly matched with the internal threads of the metal plug; the porous outer support pipe is arranged outside the outer elastic die, and the cross section of the outer elastic die is ensured to be circular;
wherein, the porous outer supporting tube and the outer elastic mould are positioned at the same axle center;
wherein the aperture of the porous outer support tube is 30 percent of the tube diameter, and the distance between every two holes is 5 mm;
the metal plug and the outer elastic mould are sealed through the holding inclined plane;
wherein, the length of the ceramic rod after molding is determined by the positions of the porous outer supporting tube and the metal plug.
Compared with the prior art, the beneficial effects of the utility model are that: the ceramic rod pressing by using the die can avoid the fracture of the blank body, the operation is simple and easy, and the requirement of large-scale production can be met.
Drawings
FIG. 1 is a structural diagram of the isostatic pressing mold of the present invention;
in the figure: (1) the device comprises an outer elastic die, (2) a porous outer support pipe, (3) a metal plug, (21) a support pipe external thread, (31) a plug internal thread, and (32) a holding inclined plane.
Detailed Description
As shown in fig. 1, the utility model relates to a solid bar wet bag type equal static pressure forming die, which comprises an outer elastic die (1), a porous outer supporting tube (2) arranged outside the outer elastic die (1) and metal plugs (3) arranged at two ends of the outer elastic die; an internal thread (31) and an elastic mold holding inclined plane (32) are arranged at the groove of the metal plug (3); external threads (21) are arranged at two ends of the porous outer supporting pipe (2) and are tightly matched with the internal threads (31) of the metal plug;
fixing an outer elastic mold, a porous outer support pipe and a metal plug on an operation platform, firstly rotating the metal plug to fixedly connect the metal plug with the porous outer support pipe, and simultaneously clasping and sealing the outer elastic mold and the metal plug; then filling the powder into the inner part of the outer elastic mould, and compacting; and finally, installing the metal plug at the other end in the same way.
When the mould is pressed, the liquid medium acts on the outer elastic mould through the holes of the porous outer supporting pipe, so that the outer elastic mould is axially compressed integrally; meanwhile, the two ends of the outer elastic die are sealed and fixed through the metal plugs, so that longitudinal compression of the outer elastic die is avoided, and breakage of the ceramic solid rod in the longitudinal direction is avoided.
The solid rod wet bag type isostatic pressing mould provided by the utility model is described in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the methods and core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the claims of the present invention.
