Abstract
The utility model belongs to the field of preparing ceramic material, and particularly relates to a die for preparing a pressureless sinterted ceramic blank body. The die is composed of a press head, a sleeve, a base and a press ring, and is characterized in that the press head is composed of an upper cylinder and a lower cylinder, wherein the bottom diameter of the upper cylinder is smaller than that of the lower cylinder. The height of the sleeve is smaller than the integral height of the press head, and the sleeve is sheathed on the lower cylinder of the press head. The base is a cylinder with a diameter larger than the outer diameter of the sleeve. The upper bottom surface of the base is provided with a cylindrical lug boss of which the diameter is the same as the bottom diameter of the lower cylinder. The inner diameter of the press ring is larger than the inner diameter of the sleeve, but smaller than the outer diameter of the sleeve. The height of the press ring is larger than the height of the blank body. The utility model with low cost and easy use is especially suitable for preparing simple and easily manufactured strip-shaped blanks.
Description
Technical field:
The utility model belongs to field of ceramic material preparation, particularly a kind of mould that is used to prepare the pressureless sintering ceramic body.
Background technology:
The mould of existing preparation pressureless sintering ceramic body has a variety of, but cost is generally all than higher, and complex structure, makes difficulty.At do experiment, especially for research advanced composite material (ACM) and sintering processing thereof, simple, convenient, safety and lower-cost mould are well suited for test requirements document.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the mould of a kind of cost preparation pressureless sintering ceramic body low, easy to use is provided.
The utility model is realized in the following manner:
A kind of mould for preparing the pressureless sintering ceramic body is made up of pressure head, sleeve, base and pressure ring, it is characterized in that pressure head is made up of last cylinder and following cylinder two parts, and last cylindrical bottom surface diameter is less than descending cylindrical bottom surface diameter; The height of sleeve is sleeved on the following cylinder of pressure head less than the pressure head whole height; Base is a cylinder, is positioned at the sleeve lower end, and diameter is greater than the external diameter of sleeve; The upper bottom surface of base has a cylindrical boss, and the boss diameter is identical with the following cylinder bottom surface diameter of pressure head; The internal diameter of pressure ring is greater than sleeve diameter, and less than sleeve outer diameter, the pressure ring height is greater than the height of base substrate.
The mould of above-mentioned preparation pressureless sintering ceramic body is characterized in that the height of pressure ring aspect ratio base substrate is big 3～6 millimeters.
When carrying out pressing mold, earlier sleeve is placed on the base, powder raw material is packed in the sleeve, then pressure head is put into sleeve, whole device is placed on carries out pressing mold under the press ram again.Pressing mold finishes, and base is taken off, and replaces its position with pressure ring, puts into once more under the press ram, and base substrate is extruded.The effect of pressure ring is just auxiliary to extrude sleeve with base substrate, and the inside and outside footpath of its inner diameter d and sleeve (d1, d2) meets the relation of d1＜d＜d2, highly needs only the height less times greater than base substrate, and the contact of base substrate discord pressure head gets final product when guaranteeing pressed compact.Particularly do experiment, can be used as the mould of producing the blank that simply, easily is processed into batten at the research material ergonomist.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a pressure ring structural representation of the present utility model.
1 is pressure head among the figure, and 2 is sleeve, and 3 is ceramic powder, and 4 is the boss above the base, and 5 is base.
The specific embodiment:
Provide a most preferred embodiment of the present utility model below in conjunction with accompanying drawing
Wherein fall head is 100 millimeters, and last body diameter is 44 millimeters, and long 47 millimeters, following body diameter is 50
-0.01 0Millimeter, its surface roughness is 0.8; The sleeve height is 50 millimeters, and external diameter is 80 millimeters, and internal diameter is 50
0 + 0.01Millimeter, its inside surface roughness is 0.8; Substructure height is 12 millimeters, and diameter is 88 millimeters, the boss diameter 50 that links to each other above it
-0.02 0Millimeter highly is 3 millimeters.Assembling process is as follows: sleeve is placed on the base, in powder raw material reversed stream tube, pressure head is slowly put into sleeve, whole device is placed on carries out pressing mold under the press ram then.Pressing mold finishes, and base 4 is taken off, and replaces its position with pressure ring 5, puts into press ram once more 1 time, and the sample circle base that presses is extruded.It is the trial circle base that 50 millimeters height are the 4-6 millimeter that this device can be produced diameter.
