Description
Technical field
This utility model belongs to fluorescent tube manufacture technology field, and in particular to a kind of monoblock type ceramic lamp tube producing device.
Background technology
Use transparent Al2O3Ceramics replace quartz glass making metal halide fluorescent tube, improve Metal halogen lamp luminous efficiency,
Color rendering index and life-span, but Metal halogen lamp pipe is more reasonably shaped as two ends band tubule（Sealing electrode is used）, middle part be ellipsoid
Shape is spherical, and this brings great difficulty to the molding of ceramic lamp tube base substrate.It is main with sodium iodide just to grow up in recent years
The white sodium vapor lamp of luminescent substance, it is also desirable to the tube like transparent aluminium oxide ceramics fluorescent tube with arc using elliposoidal or two ends.
In conventional ceramic metal halide fluorescent tube production, a class is global formation, such as injection forming, injection moulding, can fusible core
Mold forming etc..One class is sectional forming, then splice it is integral be sintered, i.e. five sets of so-called three-piece, if using
Tubulose base substrate carries out splicing sintering, often to produce dead angle, causes luminescent substance to pile up, and affects luminous efficiency and life-span.
The content of the invention
It is to carry that this utility model makes improvement, i.e. the technical problems to be solved in the utility model for above-mentioned problem
For a kind of monoblock type ceramic lamp tube producing device, the fluorescent tube qualification rate that this monoblock type ceramic lamp tube producing device is produced is high,
With preferable luminous efficiency, service life is longer.
In order to solve above-mentioned technical problem, the utility model proposes such a monoblock type ceramic lamp tube producing device,
Including metal top cover mould, metal lower supporting mold, the metal outer mold being arranged between the metal top cover mould and the metal lower supporting mold,
The hollow thin-wall polypropylene core of the metal outer mold inside center is arranged on, it is interspersed in the middle of the hollow thin-wall polypropylene core
There is a tungsten alloy core bar, the metal outer mold forms cavity, the metal top cover mould with the hollow thin-wall polypropylene core
On offer gel material feeding slurry inlet, gel material feeding slurry inlet is connected with the cavity；The hollow thin-wall poly- third
Alkene core is shaped as spheroid, and wall thickness is 0.05mm～0.2mm；The metal top cover mould is inserted in the tungsten alloy core bar upper end,
Insert the metal lower supporting mold in lower end；The gel filled material feeding slurry of the cavity, the gel material feeding slurry suppresses containing grain growth
High-purity Al of agent2O3Powder, and add the dispersant for increasing mobility；The number of the hollow thin-wall polypropylene core is at least 1
It is individual.
The beneficial effects of the utility model：
The fluorescent tube qualification rate that this monoblock type ceramic lamp tube producing device of this utility model is produced is high, sends out with preferable
Light efficiency, service life is longer.
Description of the drawings
This utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is this utility model structural representation；
In figure：1st, metal top cover mould；2nd, metal lower supporting mold；3rd, metal outer mold；4th, tungsten alloy core bar；5th, hollow thin-wall poly- third

Specific embodiment
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 the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
As shown in figure 1, being a kind of embodiment of the present utility model, a kind of monoblock type ceramic lamp tube producing device, including gold
Cover mold 1, metal lower supporting mold 2, the metal outer mold 3 being arranged between metal top cover mould 1 and metal lower supporting mold 2 on category, it is arranged on gold
The hollow thin-wall polypropylene core 5 of the category inside center of external mold 3, is interspersed with a tungsten alloy in the middle of hollow thin-wall polypropylene core 5
Core bar 4, metal outer mold 3 forms cavity 7 with hollow thin-wall polypropylene core 5, and gel material feeding slurry note is offered on metal top cover mould 1
Entrance 6, gel material feeding slurry inlet 6 is connected with cavity 7；Hollow thin-wall polypropylene core 5 is shaped as spheroid, and wall thickness is
0.05mm～0.2mm；Metal top cover mould 1 is inserted in the upper end of tungsten alloy core bar 4, and metal lower supporting mold 2 is inserted in lower end；The filling of cavity 7 is solidifying
Glue injecting material is starched, gel material feeding high-purity Al of the slurry containing grain growth inhibitor2O3Powder, and add the dispersant for increasing mobility；
The number of hollow thin-wall polypropylene core 5 is at least 1.
During concrete application, metal outer mold 3 and hollow thin-wall polypropylene core 5 are pressed after given size assembly first, both
Between will form the cavity 7 that matches with ceramic lamp tube shape；Modulated gel material feeding is starched, wherein containing grain growth inhibitor
High-purity Al2O3The solid volume content of powder reaches 50～55, and adds the dispersant for increasing mobility；Gel material feeding slurry is noted
In entering cavity 7, the mobility starched by gel material feeding and applied vibration are allowed to full of whole cavity 7；By metal outer mold 3, hollow
Thin-walled polypropylene core 5 is put in people's baking oven together with gel material feeding slurry, is progressively heated to 50～60 DEG C, makes gel material feeding slurry solidification；
Metal outer mold 3 is unloaded, together with hollow thin-wall polypropylene core 5 ceramic lamp tube base substrate is taken out in the lump.
The fluorescent tube qualification rate that this monoblock type ceramic lamp tube producing device of this utility model is produced is high, sends out with preferable
Light efficiency, service life is longer.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in this utility model
