Abstract
The utility model relates to a static-pressure shaping mould for a ceramic rod, composed of an inner mould (1) of a hollow stainless steel pipe, an oil-resistant rubber outer mould (2) and a sealing plug (3). The ceramic rod body through static-pressure shaping adopting the mould has the advantages of low deformation, small contraction after calcination, good linearity of products and easy demoulding, and the rate of productsmeeting standards can reach more than 80 percent, which is favorable for mass production with large scale.
Description
The utility model relates to a kind of shaping dies of ceramic rod, particularly the mould that is shaped for isostatic pressing method.
The manufacturing process of existing ceramic rod, the one, extrusion, it is extruded into the ceramic rod idiosome on one trough plate by a tube extruding machine; The 2nd, slip casting method, it adopts heavy gypsum mold, and not only labour intensity is big, efficient is low, and is difficult to form large-scale mass production.
The purpose of this utility model provides that a kind of shaping is easy, yield rate is high, and can adapt to the ceramic rod hydrostatic pressing mould of large-scale batch production.
The utility model is finished like this:
With hollow stainless steel tube as internal mold (1), its pipe thickness equal or＞in 1mm, linearity＜0.1%(total length); With oil resistant rubber as external mold (2), its pipe thickness equal or＞1mm; Make two sealing-plugs (3) with rubber or other suitable materials.Sealing-plug during use (3) is positioned at the two ends of mould, inserts between internal mold (1) and the external mold (2).The size of mould is set according to the specification of product.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Accompanying drawing is a structure chart of the present utility model.
Get one long 4 meters hollow stainless steel tube and make internal mold (1), pipe thickness is 1.5mm, and two of stainless steel tube is not sealed.Make external mold (2) with oil resistant rubber, its wall thickness is 1.5mm.The diameter of interior external mold is looked the specification of the ceramic rod of production and is set size.The width of the tubular idle loop that forms between internal mold (1) and the external mold (2) is the pipe thickness of ceramic rod idiosome (4).Sealing-plug (3) is the ring-type plug, and middle idle loop diameter is pressed the diameter of stainless steel tube and set, and can be inserted in stainless steel tube and coincide more tightly to get final product.The diameter of sealing-plug (3) should be greater than more than external mold (2) the internal ring wall diameter 1mm, and an inside side is opened an inclined-plane (5), and identical with the diameter of ceramic rod idiosome (4) by the sealing-plug diameter of inclined-plane one side, its pipe thickness is also consistent with idiosome.
The specific operation process of using above-mentioned mould to produce ceramic rod is: with a tube extruding machine stock for preparing is expressed to stainless steel tube internal mold (1) and goes up the idiosome (4) that forms ceramic rod, the idiosome (4) that will have internal mold (1) puts rubber external mold (2), two sealing-plugs (3) are filled in respectively between the internal mold (1) and external mold (2) at two, be advisable to push up idiosome (4).It is to pressurize in the autoclave of pressure medium that this class mould that has idiosome (4) that then will be is in batch put into oil.After the pressurization, extraction of closure plug (3) is deviate from interior external mold, just the ceramic rod idiosome can be sintered into product.
Adopt the ceramic rod idiosome of above-mentioned mould through hydrostatic pressing, the calcining after-contraction is little, and distortion is few, and the product linearity is good, and size is accurate, and product percent of pass can reach more than 80%.Adopt stainless steel tube to make internal mold, smoothness is higher, and adopts rubber to make external mold, easily expands after the release, and therefore interior external mold is all more easily taken out from idiosome and taken off, i.e. the demoulding is easy, thereby helps forming large-scale mass production.
Claims (3)
1, a kind of ceramic rod hydrostatic pressing mould is characterized in that being made up of hollow stainless steel tube internal mold (1), oil resistant rubber external mold (2) and two sealing-plugs (3).
2, according to the described ceramic rod hydrostatic pressing of claim 1 mould, it is characterized in that internal mold (1) is hollow-core construction, two ends are not sealed; One side of sealing-plug (3) has an inclined-plane (5).
3, according to the described ceramic rod hydrostatic pressing of claim 1 mould, the pipe thickness that it is characterized in that the pipe thickness of internal mold (1) and external mold (2) equal or＞in 1mm; The diameter of sealing-plug (3) inclined-plane one side is identical with the idiosome diameter, and the sealing-plug diameter beyond the inclined-plane is greater than more than external mold (2) the internal ring wall diameter 1mm.
