Description
Technical field
The present invention relates to the molding side of ceramic die field, more particularly to a kind of hollow ceramic mould and hollow ceramic component
Method.
Background technology
For the hollow ceramic component that shape matching is complicated in prior art, such as one section bend pipe, one section of spiral bending tube, one
Section Y types bend pipe or some other irregular passage ceramic component, its manufacture method typically have two methods.One kind is to adopt
The method that traditional gypsum mold slip casting is dried forms passage, and this method is applied to the less demanding pottery of forming precision
Component；Another kind of method is first to make connection chipware using some organic materials by channel shape, fixes connector with core pulling
In finished product die, reinject ceramic size and make idiosome, first passing through before the firing either physically or chemically will connection chipware erosion
Empty method makes required ceramic component, and this method is used for the making of high technology ceramics.At present, both approaches are in the application
Have some limitations.For first method, the profile of idiosome can be with more accurate control, but the uncontrollable essence of inner chamber
Degree, for connecting during other components, it is impossible to realizes agreeing with, although by interior rounding and can polish mode and reaches required precision,
But interior rounding simultaneously polishes mode and is not particularly suited for needing the component with thread mutual connection；For second method, easily can fit
For the ceramic component of simple shape, but the ceramic component for complicated shape, the method is limited because of the core pulling that can be arranged, even
Connect chipware stably to fix in finished product die, the ceramic component so as to make can be larger because of inner chamber and design requirement generation
Deviation and can not use, in addition, the method is in manufactured goods mold base body, easily the air bag in die cavity in idiosome is caused to make
Into ceramic component existing defects.
Content of the invention
The technical problem to be solved is：There is provided a kind of suitable for making is complex-shaped and required precision is high
The hollow ceramic mould of empty ceramic component, and and then provide a kind of forming method of hollow ceramic component.

A kind of hollow ceramic mould, with die cavity, one end of the die cavity is provided with the casting portion with sprue gate, the type
The other end in chamber is provided with the intake section with air inlet, is provided with air valve at the air inlet.
The beneficial effects of the present invention is：
(1) compared with traditional moulds combination, the hollow ceramic mould structure of the present invention is simple, due to connecting core
Part, overcome due to connect chipware there are problems that two cause ceramic idiosome easily to be subsided, shrinkage cavity and；
(2) structure design of hollow ceramic mould of the invention can effectively reduce the residual stress of idiosome, obtained
Hollow ceramic idiosome is mellow and full full, meanwhile, the structure can be obtained the conventional methods such as helical form hollow ceramic idiosome cannot be obtained
Accurate hollow ceramic product.
Invention additionally discloses a kind of method using above-mentioned hollow ceramic mould molding hollow ceramic component, including following step
Suddenly：
(1) ceramic size of melting is filled the hollow ceramic mould by sprue gate；
(2) when ceramic size in the hollow ceramic mould die cavity inner surface formed cured layer when, by air inlet to
Injection gas in die cavity, the ceramic size that there is mobility still in die cavity is discharged by sprue gate, is obtained and is had and die cavity shape
The hollow ceramic idiosome of shape identical hollow channel；
(3) cooling shaping, the demoulding, are obtained hollow ceramic component.
The method of the molding hollow ceramic component of the present invention has the beneficial effect that：
(1) compared with traditional gypsum mould grouting method, and hollow obtained in the method for the preparation hollow ceramic of the present invention
Ceramic component has higher precision and smoothness, can apply to high technology ceramics field；
(2) method of molding hollow ceramic component of the invention is overcome due to connecting core due to connecting chipware
There are problems that of part two causes ceramic idiosome easily to be subsided, shrinkage cavity and, while shorten the embryo cycle processed, improve production efficiency,
Save raw materials for production.Meanwhile, the conventional methods such as helical form bend pipe can be obtained cannot obtained high technology ceramics part.
