Abstract
The utility model discloses an abnormal shape ceramic lamp tube making devices, the device include mould lid on the rubber, rubber lower mould lid, set up on rubber the external mold between mould lid and the rubber lower mould lid, is provided with the steel core mould on the rubber in the middle of the mould lid bottom, and it has tungsten alloy core pole to peg graft in the middle of the steel core mould bottom, and mould lid, rubber lower mould lid, external mold and steel core mould form " Y " shape space on the rubber. The molded body density ratio that this kind of device was made is higher, and the internal surface is more smooth, than less, obtains higher luminousness because the granulation powder adds the organic matter easily in addition.
Description
Technical field
This utility model belongs to fluorescent tube manufacture technology field, is specifically related to a kind of non-conventional type ceramic fluorescent tube producing device.
Background technology
Use transparent Al2O3Pottery replace quartz glass make metal halide fluorescent tube, improve Metal halogen lamp luminous efficiency,
Color rendering index and life-span, ceramic gold-halogen lamp and white sodium vapor lamp be developed recently get up specular removal, the energy-conserving light source of high-color rendering, but
The ceramic arc tube that they are used but shape is complicated more than high-pressure sodium fluorescent tube, is two ends band tubule (sealing electrode is used), middle part
For elliposoidal or spherical, and requiring that inner chamber two ends do not form dead angle, this can cause the accumulation of luminescent substance, thus affects lamp
Light efficiency and the life-span, so arc-shaped transition is wanted at two ends, this give ceramic body molding bring great difficulty.
Have employing global formation at present, as injection forming, injection after air-pressure forming, extrude rear air-pressure forming etc.；Also adopt
With gel note or injection docking molding.But it is the most that these method granulation powders add Organic substance, and molding blank density compares
Low, inner surface is relatively rough, affects light transmission；There is seam in the fluorescent tube prepared, the life-span of lamp is comparatively short.
Therefore, being badly in need of developing a kind of ceramic lamp tube producing device, the molding blank density that this device is made is higher,
Inner surface smoother, and owing to granulation powder interpolation Organic substance is fewer, it is readily available higher light transmittance.
Summary of the invention
This utility model makes improvement for the problem of above-mentioned existence, i.e. the technical problems to be solved in the utility model is to carry
For a kind of non-conventional type ceramic fluorescent tube producing device, the molding blank density that this device is made is higher, inner surface smoother, and
And owing to granulation powder interpolation Organic substance is fewer, it is readily available higher light transmittance.
In order to solve above-mentioned technical problem, the utility model proposes such a non-conventional type ceramic fluorescent tube producing device, should
Device includes die cap under rubber upper mould cover, rubber, is arranged on the external mold between die cap under described rubber upper mould cover and described rubber,
Bottom described rubber upper mould cover, centre is provided with steel core die, and bottom described steel core die, centre is plugged with tungsten alloy core bar, described rubber
Under glue upper mould cover, described rubber, die cap, described external mold and described steel core die form Y-shaped space；Described rubber upper mould cover width
More than the width of die cap under described rubber, described external mold by joinery and its construction respectively with under described rubber upper mould cover and described rubber
Die cap connects；The width of described external mold is wide at the top and narrow at the bottom；Described steel core die is inserted in described tungsten alloy core bar upper end, and institute is inserted in lower end
State die cap under rubber；Described Y-shaped space wadding warp crosses the transparent Al of mist projection granulating2O3Ceramic powder.
The beneficial effects of the utility model:
This utility model this non-conventional type ceramic fluorescent tube producing device is relatively simple for structure, and the molding blank density made compares
Height, inner surface smoother, and owing to granulation powder interpolation Organic substance is fewer, it is readily available higher light transmittance.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation；
In figure: 1, rubber upper mould cover, 2, die cap under rubber, 3, external mold, 4, steel core die, 5, tungsten alloy core bar, 6, Y-shaped empty
Between.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As it is shown in figure 1, be a kind of embodiment of the present utility model, a kind of non-conventional type ceramic fluorescent tube producing device, this device bag
Include die cap 2 under rubber upper mould cover 1, rubber, be arranged on the external mold 3 between die cap 2 under described rubber upper mould cover 1 and described rubber,
Bottom described rubber upper mould cover 1, centre is provided with steel core die 4, and bottom described steel core die 4, centre is plugged with tungsten alloy core bar 5, institute
State die cap 2, described external mold 3 and described steel core die 4 under rubber upper mould cover 1, described rubber and form Y-shaped space, on described rubber
Die cap 1 width more than the width of die cap 2 under described rubber, described external mold 3 by joinery and its construction respectively with described rubber upper mould cover 1
Connecting with die cap 2 under described rubber, the width of described external mold 3 is wide at the top and narrow at the bottom, and described steel is inserted in described tungsten alloy core bar 5 upper end
Core 4, die cap 2 under the described rubber of lower end insertion, described Y-shaped space 6 wadding warp crosses the transparent Al of mist projection granulating2O3Ceramics
Body.
During making, according to the requirement of ceramic lamp tube half size, make external mold 3 and hardened steel core and connect in end
Upper tungsten alloy core bar 5, after external mold 3 coordinates with steel core die 4, the Y-shaped space 6 of formation conforms exactly to the shape of half ceramic lamp tube
Shape.
By the transparent Al through mist projection granulating2O3Ceramic powder is filled to Y-shaped space 6, then seals up rubber top cover.
The composite die filling crystalline ceramics pelletizing is put in the working chamber of dry bag method isostatic pressed, then apply
The hydrostatic pressure of 180 Mpa, makes powder body become half elliposoidal (cup-shaped) compacts with some strength, then from mould
Middle taking-up.
This utility model this non-conventional type ceramic fluorescent tube producing device is relatively simple for structure, and the molding blank density made compares
Height, inner surface smoother, and owing to granulation powder interpolation Organic substance is fewer, it is readily available higher light transmittance
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
