It does not have any seam to make the integral ceramic lamp tube that equipment made through this kind, has reduced the probability that produces the defect, has improved the life of lamp.
Description
Technical field
The utility model belongs to fluorescent tube manufacturing technology field, and in particular to a kind of isostatic pressing method molding integral ceramic lamp tube
Making apparatus.
Background technology
Use transparent Al2O3Ceramics replace quartz glass making metal halide fluorescent tube, improve Metal halogen lamp luminous efficiency,
Colour rendering index and life-span, ceramic gold-halogen lamp and white sodium vapor lamp are specular removal, the energy-conserving light sources of high-color rendering that developed recently gets up, but
But shape is complicated more than high-pressure sodium fluorescent tube for the ceramic arc tube that they are adopted, and is two ends band tubule（Sealing electrode is used）, middle part
For elliposoidal or spherical, and require that inner chamber two ends should not form dead angle, this can cause the accumulation of luminescent substance, so as to affect lamp
Light efficiency and the life-span, so arc-shaped transition is wanted at two ends, this brings great difficulty to the shaping of ceramic body.
Adopt global formation at present, air-pressure forming such as after injection forming, injection, extrude rear air-pressure forming；Also adopt
Docking shaping is noted or injected with gel.But these method granulation powders addition organic matters are relatively more, molding blank density ratio compared with
Low, the light transmittance of acquisition is relatively low；There is seam in obtained fluorescent tube, the life-span of lamp is shorter.
It is therefore proposed that a kind of making apparatus by isostatic pressing method molding integral ceramic lamp tube, are realized by the equipment
Isostatic pressing method molding integral ceramic lamp tube.
The content of the invention
It is to carry that the utility model makes improvement, i.e. the technical problems to be solved in the utility model for above-mentioned problem
For a kind of making apparatus of isostatic pressing method molding integral ceramic lamp tube, by monoblock type ceramic lamp obtained in this making apparatus
Pipe reduces the probability for producing defect without any seam, improves the service life of lamp.
In order to solve above-mentioned technical problem, the utility model proposes such a isostatic pressing method molding integral ceramic lamp
The making apparatus of pipe, including rubber upper mould, rubber lower mould, be arranged on the rubber upper mould and the rubber lower mould it
Between external mold, the external mold bosom is provided with core, in the middle of the core thin metal rod is inserted with, to form ceramic lamp tube institute
The two ends capillary for needing, between the external mold and the core space is formed, and the space is exactly the shape of bulk ceramics fluorescent tube, institute
State upside external mold and downside external mold that external mold includes connecting by joinery and its construction；Upside external mold is by joinery and its construction and the rubber
Upper mould connects, and the downside external mold is connected by joinery and its construction with the rubber lower mould；The core is can to distil or can
Core made by the material of cold melt；Fill containing the transparent of grain growth inhibitor, dispersant and binding agent in the space
Al2O3Ceramic mist projection granulating material, carries out isostatic pressing.
The beneficial effects of the utility model：
Organic matter is fewer by this manufacturing equipment granulation powder to be added, and isostatic pressing blank density is higher,
Higher light transmittance can be obtained；Simultaneously obtained fluorescent tube does not have any seam, reduces the probability for producing defect, and the life-span of lamp compares
It is stable.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the utility model structural representation；
In figure：1st, rubber upper mould, 2, rubber lower mould, 3, external mold, 31, upside external mold, 32, downside external mold, 5, thin gold
Category bar, 6, core, 7, space.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
As shown in figure 1, be a kind of embodiment of the present utility model, a kind of system of isostatic pressing method molding integral ceramic lamp tube
Making equipment includes rubber upper mould 1, rubber lower mould 2, is arranged between the rubber upper mould 1 and the rubber lower mould 2
External mold 3, the bosom of the external mold 3 is provided with core 6, thin metal rod 5, the external mold 3 and institute is inserted with the middle of the core 6
Formation space 7 between core 6 is stated, the external mold 3 includes upside external mold 31 and the downside external mold 32 connected by joinery and its construction；Institute
State upside external mold 31 to be connected with the rubber upper mould 1 by joinery and its construction, the downside external mold 32 is by joinery and its construction and institute
State rubber lower mould 2 to connect；The core 6 is can to distil or can core made by the material of cold melt；Fill in the space 7
Transparent Al containing grain growth inhibitor, dispersant and binding agent2O3Ceramic mist projection granulating material.
During making, first according to translucent ceramic lamp vessel design shape, prepare isostatic pressed method shaping external mold 3 and
Can distil or can cold melt material make core 6, thin metal rod 5 is inserted with core 6, two needed for form ceramic lamp tube
End capillary, the space 7 that external mold 3 is formed after assembling with core 6 is exactly the shape of bulk ceramics fluorescent tube；
Transparent Al2O3 containing grain growth inhibitor, dispersant and binding agent ceramics mist projection granulating material are packed into interior
In the space 7 that outer mold is formed, isostatic pressing is then carried out；
Removing external mold 3, takes out the thin metal rod 5 in core 6, then carries out low-temperature heat, excludes sublimate or eutectic
The core 6 that point material is made, obtains complete ceramic lamp tube base substrate.
Organic matter is fewer by this manufacturing equipment granulation powder to be added, and isostatic pressing blank density is higher,
Higher light transmittance can be obtained；Simultaneously obtained fluorescent tube does not have any seam, reduces the probability for producing defect, and the life-span of lamp compares
It is stable.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
