Abstract
The utility model relates to a press shaping mould ring of color kinescope glass bulb, which comprises a mould ring body and a mould ring guiding part which extends out of the outer lateral surface of the mould ring body, wherein the mould body is provided with a flange which inwards extends out of an upper surface, the flange can position glass bulbs shell to be shaped which are arranged in the mould ring and the outer lateral wall of the mould ring body is provided with a plurality of cooling troughs. Owing to the cooling troughs arranged on the mould ring, the thickness of the mould ring is reduced, heat radiation area is increased simultaneously, and the mould ring can be forcibly cooled via cooling air so as to change the cold/heat temperature characteristic of the mould ring. With controlling the number, dimension, position, etc. of the cooling troughs, the utility model can rapidly cool the mould ring temperature to a certain range and control the heat balance of the mould rings, glass screens and screen cones, therefore the sealing surfaces of the glass screens and the glass cones can be cured and shaped with stable product data.
Description
Technical field
The utility model relates to a kind of heat pressing and molding mold that is used for glasswork; Particularly, the utility model relates to a kind of shaping mould circle that is used for the hot pressing color picture tube glass bulb.
Background technology
Colour picture tube glass screen and glass awl pass through mould compression moulding by press with high temp glass liquid.The shaping mould that disposes on the press has punch, mould circle and bed die.Put it briefly, the glass bulb pressing process is that high temperature glass frits is splashed in the bed die, makes to rush in the row compacting under the punch, and the cooling by mould after glass bulb compression moulding is cured typing.Screen die is used for the skirt section and the sealing surface of moulding glass screen, and the prod cast circle is used for the sealing surface of moulding glass awl.Glass will be shielded sealing surface and glass awl sealing surface in picture tube company cooperates and seals up.The sealing surface thickness and the sealing surface perimeter data of glass screen and glass awl should be controlled in certain tolerance on fit scope.This shows that the mould circle is the vitals of glass bulb cooling forming, the temperature of control mould circle is very important.In actual production process, need carry out cooling process to the mould circle, so that the mould circle is at the regular hour internal cooling and be controlled in certain temperature range.
In present color picture tube glass bulb was produced, owing to increase substantially glass screen output, the press work tempo was accelerated, and required glass screen skirt section, glass screen sealing surface, glass awl sealing surface to realize cooling within a certain period of time more, to reach the specification of quality to glass bulb.Mould circle method of cooling conventional in the prior art is a naturally cooling and air-cooled, but because mould circle wall thickness is thicker, be difficult in the specific time glass screen is cooled down, therefore very easily cause glass defects such as collapse in the sealing-in limit, peripheral scattered error big, bight distortion, the super scope of screen awl tolerance on fit.
Therefore, the cooling that how to improve the mould circle improves screen awl sealing surface to cooperate with to adapt to the work tempo of accelerating day by day is those skilled in the art's problem demanding prompt solution always.
The utility model content
Based on the above-mentioned defective that exists in the prior art, the color picture tube glass bulb that the purpose of this utility model is to provide a kind of can solve the too high problem of in glass bulb manufacturing processed temperature, improve the cooperation of screen awl sealing surface is pressed into the pattern circle.
According to the utility model, provide a kind of color picture tube glass bulb to be pressed into the pattern circle, it comprises mould circle body and from the outwardly directed mould circle of the outer side guide part of mould circle body, this mould circle body has the surperficial from it flange that inwardly stretches out so that the glass bulb to be formed that is placed in the mould circle is carried out maintenance, offers a plurality of cooling tanks on the outer side wall of mould circle body.
Owing on the mould circle, have cooling tank, make mould circle reduced thickness, increased area of dissipation simultaneously, can force cooling to the mould circle by cooling air, to change the cold and hot temperature profile of mould circle.Quantity by the controlled chilling groove, size, position etc. can make mould circle temperature be cooled to certain limit rapidly, the thermal equilibrium of control mould circle, glass screen, screen awl, thus making glass screen, glass awl sealing surface curing molding, product data are stable.

Specific embodiments
The picture tube glass bulb screen is what by supporting forming mould high temp glass is pressed on press.Forming mould mainly comprises punch, mould circle and bed die.
As Fig. 2 and shown in Figure 4, color picture tube glass bulb screen is pressed into that pattern circle 1 comprises mould circle body 3 and from the outwardly directed mould circle of the outer side guide part 4 of mould circle body.On this mould circle guide part, can be provided with threaded hole, to realize the fixing of this mould circle by bolt.On the outer side wall of mould circle body 3, offer a plurality of cooling tanks 2.This cooling tank can be set to cool off vertical slot along the short transverse of the outer side wall of mould circle body.Perhaps, also can offer a plurality of horizontal cooling tanks (cooling translot) along the direction parallel with the upper and lower surface of mould circle body cardinal principle.
Preferably, these a plurality of cooling vertical slots or cooling translot can be symmetrical arranged with respect to the longitudinal center's axis and the central transverse axis of mould circle body 3.
Referring to Fig. 3, mould circle body 3 has the flange 5 that inwardly stretches out from its medial surface so that the glass bulb to be formed that is placed in the mould circle is carried out maintenance.
This cooling vertical slot or cooling translot can adopt the form of rectangular tank or arc groove.As shown in Figure 2, according to the characteristic of glass bulb to be formed and the mould circle temperature of required control, can process width on the outer side wall of mould circle body is that 8-16mm, spacing are a plurality of vertical rectangular tank or the arc groove of 20-30mm.
According to actual production conditions, the cooling vertical slot on also can mould circle outer side wall is set to connect the groove of whole mould circle body outer side wall height.
Those skilled in the art will appreciate that offering of cooling tank is not limited to the mode shown in Fig. 2.According to needs of production, can optionally cooling tank be opened in the long limit of mould circle body outer side wall, the minor face of mould circle body outer side wall and/or the bight in the mould circle body outside.
Mould circle of the present utility model can be determined quantity, size, the position of cooling tank according to production actual needs such as for example formed product characteristic or mould circle temperature, adopts numerically-controlled machine to process.
According to the utility model, by on the mould circle, offering cooling tank, the reduced thickness of mould circle, and increased area of dissipation.By cooling air the mould circle is forced cooling, can significantly change the cold and hot temperature profile of mould circle.
According to the utility model, can be according to the situ production needs, the quantity of controlled chilling groove, size and position etc. make mould circle temperature be cooled to certain limit rapidly.By the thermal equilibrium of control mould circle, glass screen, screen awl, make glass screen, glass awl sealing surface curing molding, product data are stable, guaranteed quality product and improved production efficiency.
