Description

The integrated slip casting device of ceramic arc tube base substrate

Technical field

The utility model relates to the integrated slip casting device of a kind of ceramic arc tube base substrate.

Background technology

Metal halogen lamp is a third generation high strength gas electric light source (HIP) in the world at present; Not only light efficiency is high, brightness is high, photochromic good for the core product that is called as 21 century environmental protection illumination, Metal halogen lamp, and colour rendering index is high, decay resistance is strong, the life-span is long; More traditional quartz glass discharge vessel has the operating temperature height; Rational and the more stable advantage of chemical property of high temperature substrate, its composite index is very superior, is present optimal energy-efficient light source.Ceramic arc tube is the main part of the crux of Metal halogen lamp, and because of its boring structure, the difficulty of moulding is very big.The ceramic arc tube of PHILIPS Co. research and development is to use many sleeve forming technology, divides three or five bondings to form, and the bonding difficulty of ceramic product is big, specification requirement is high, take a lot of work and time-consuming; Cause the yield rate of product low; Moreover the temperature when working because of ceramic arc tube can receive high temperature impact up to 1200 ℃, can make ceramic arc tube produce very big internal stress; Cause the gas leakage of ceramic fulgurite adhesive portion or break, have a strong impact on the service life of ceramic arc tube.

Summary of the invention

In order to overcome existing in prior technology the problems referred to above; The purpose of the utility model provides the integrated slip casting device of a kind of ceramic arc tube base substrate, and the deformation simple and compact for structure, easy to operate, base substrate of the slip casting device of this ceramic arc tube base substrate is few, yield rate is high.

The utility model realizes that the technical pattern scheme that above-mentioned purpose adopted is: comprise mould; Mould is made up of butt joint fixing upper mold section and female die; Form coaxial setting and die cavity that joins and via hole between upper mold section that connects and the female die; In axial direction pass core in die cavity and the via hole, the axial two ends of mould are bearing on the support through the commentaries on classics of rotating shaft hinge, and rotating shaft connects power source through transmission mechanism.

Upper mold section, female die constitute by interior pattern and outer solid model socket, and on the pattern, the axial two ends of outer solid model connected rotating shaft in die cavity and via hole were arranged on.

The external grouting port of die cavity.

Check valve is set in grouting port.

The utility model is through above-mentioned concrete design, have simple and compact for structure, easy to operate, shaping speed fast, the advantage that deformation is few, yield rate is high, properties of product are stable of base substrate.

The specific embodiment

As shown in the figure, the integrated slip casting device of the utility model ceramic arc tube base substrate comprises mould; Mould is made up of with female die 2 the fixing upper mold section 1 of butt joint; Upper mold section 1 adopts porous water-absorbing property or porous transmissibility material with female die 2, like gypsum, porous resin etc., and the die cavity 4 and via hole 5 that form coaxial setting between upper mold section 1 that connects and the female die 2 and join; Die cavity 4 external grouting ports 3; Grouting port 3 should have the function that prevents that the anti-slime flux of ceramic size from going out, and in the utility model, is provided with check valve 13 in the grouting port 3.In axial direction pass core 6 in die cavity 4 and the via hole 5, the core 6 of both sides, die cavity 4 center can fuse, and also can be divided into two sections.The axial two ends of mould are bearing on the support 8 through rotating shaft 7 hinge commentaries on classics, and rotating shaft 7 connects power sources 10 through transmission mechanism 9, and power source 10 can adopt motor, also can be manual operation.Upper mold section 1, female die 2 can also be made up of

interior pattern

11 and 12 sockets of outer solid model, and interior pattern 11 adopts porous water-absorbing property or porous transmissibility material in this structure, and like gypsum, porous resin etc., and outer solid model 12 can adopt common metal or plastic material.On the pattern 11, outer solid model 12 axial two ends connected rotating shaft 7 in die cavity 4 was arranged on via hole 5.

Adopt the complete forming step of the integrated slip casting device of above-mentioned ceramic arc tube base substrate to be:

A, preparatory stage: by upper mold section 1, the female die 2 of porous water-absorbing property or porous transmissibility material such as gypsum material making belt type cavity 4 and via hole 5; Core 6 is fixed in die cavity 4 and the via hole 5; Dock the upper mold section 1 that closes then and form moulds with female die 2, mould is installed on the support 8

B, slip casting stage: in die cavity 4, inject ceramic size; As in die cavity 4, injecting ceramic size through grouting port 3, certainly, ceramic size also can add in the die cavity 4 before upper mold section 1 and female die 2 engage in advance,

C, formative stage: rotary die; By on the chamber wall attached to die cavity 4 equably, through the absorption and the drainage of porous water-absorbing property mould, ceramic size solidifies on the wall of the chamber of die cavity 4 at ceramic size under the effect of rotary centrifugal force; Form the ceramic arc tube biscuit; The rotation of mould can be adopted motor-driven, also can be manual operation

D, ejection phase: the ceramic arc tube biscuit together with the mould airing or after drying, is separated upper mold section 1 and female die 2, again base substrate 14 is deviate from together with core 6, extract core 6 at last out, accomplish the forming process of ceramic arc tube base substrate 14.

Above-described embodiment describes the preferred implementation of the integrated slip casting device of the utility model ceramic arc tube base substrate; Be not that design and scope to utility model limits; Under the prerequisite that does not break away from the utility model scheme; Various external form modification and improvement that those skilled in the art make the technical scheme of the utility model all should fall into the protection domain of the integrated slip casting device of the utility model ceramic arc tube base substrate.
