Abstract
The utility model provides a forming cooling plug capable of reducing forming stripes of optical glass strips. The forming cooling plug comprises a main body adopting a hollow structure, wherein a working face is arranged in the main body; diversion grooves are formed in the main body; a cooling medium inlet and cooling medium outlets are further formed in the main body. According to the utility model, the cooling medium enters the forming cooling plug from the inlet and flows along the diversion grooves, under the action of external pressure and the diversion grooves, to reach the working face for heat exchange, and after passing through the diversion grooves, leaves the cooling plug from the cooling medium outlets and the cooling medium can fully exchange heat with the high temperature part of the forming cooling plug; moreover, as no dead angle exists on the working face, uniform temperature distribution on the working face is guaranteed and defects such as stripes of a product caused by uneven temperature distribution on a forming die are reduced.
Description
Technical field
The utility model relates to glass production field, particularly relates to the cooling plug of the moulding using in a kind of glass ware forming.
Background technology
In the time producing opticglass, high temp glass liquid, from discharge nozzle flows out, flows directly in forming mould under gravity and traction External Force Acting.The temperature of glass liquid that discharge nozzle flows out is when higher, and the temperature that glass metal arrives forming mould is also higher, and this need to lower the temperature for a long time, easily causes glass to stay, thereby makes glass occur transverse wave; In addition, glass is for a long time in pyroprocess, and in glass, volatile component volatilization seriously, causes glass phase-splitting, occurs striped; Further, when glass cooling rate is slow, the time that rests on crystallization interval in glass ware forming process increases, and easily occurs crystallization striped.
The general forming end plug that adopts blows out cooling gas at present, the temperature of fast reducing glass metal, while making glass metal arrive forming mould, cross recrystallization temperature interval, thereby can reduce separating out of crystal in moulding process, simultaneously, the reduction of mold temperature can reduce glass surface volatilization, alleviates phase-splitting, the final volatilization moulding striped that reduces.
Current forming end plug generally has circular cooling channel on upper and lower centerplane.Heat-eliminating medium is from entering away from glass metal section, by behind cooling channel again from flowing out away from metal level.The problem that this structure exists: in moulding process, heat-eliminating medium, by cooling channel, absorbs the heat transmitting from cooling plug, near temperature reduction cooling channel.Because path, cooling channel concentrates on the middle part of forming end plug, there is cooling dead angle and local overcooling situation, make forming end plug near glass surface on temperature distributing disproportionation even, thereby make product occur striped.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cooling plug of moulding that reduces optical glass strip material moulding striped.
The technical scheme that the utility model technical solution problem adopts is: the cooling plug of moulding, comprise the main body of hollow structure, in main body, be provided with working face, be provided with splitter box in described body interior, in described main body, be also provided with heat-eliminating medium entrance and heat-eliminating medium outlet.
Further, described working face is plane or cambered surface.
Further, described working face is aspheric surface.
Further, between described working face and the lower surface of main body, have angle α, α value scope is 15 °-75 °.
Further, between described splitter box, there is angle theta, θ value scope be 0 °-be less than 90 °.
Further, described main body adopts cast iron, copper, graphite material to make.
Further, described heat-eliminating medium entrance and heat-eliminating medium outlet are arranged on the non-working surface of described main body.
Further, the quantity of described splitter box is more than or equal to 1.
The beneficial effects of the utility model are: heat-eliminating medium enters the cooling plug of moulding from entrance, under the effect of external pressure and splitter box, arrive working face generation heat exchange along splitter box, and then by leaving cooling plug from heat-eliminating medium outlet after splitter box, heat-eliminating medium can carry out heat exchange with the cooling plug high temperature position of moulding of the present utility model fully, and on working face, there is no dead angle, can guarantee uniformity of temperature profile on working face, reduce product because of the even defects such as striped that cause of temperature distributing disproportionation on forming mould.The utility model is by changing circulation path and the cooling range of heat-eliminating medium in moulding cooling plug, the high temperature end face of the cooling plug of moulding is all subject to cooling, and temperature distribution is more even, can effectively prevent the moulding striped causing because of temperature distributing disproportionation.

Embodiment
As Figure 1-Figure 4, the cooling plug of moulding of the present utility model comprises the main body 3 of hollow structure, is provided with working face 5 in main body 3, and working face 5 is contact surfaces of the cooling plug of moulding and glass metal, is also the heat exchange surface of heat-eliminating medium.Working face 5 can be plane, cambered surface and aspheric surface.Between the lower surface of working face 5 and main body 3, have angle α, α value scope is 15 °-75 °.Be provided with splitter box 4 in main body 3 inside, the quantity of splitter box 4 is more than or equal to 1, and what in Fig. 3 and Fig. 4, draw is 2 splitter boxs 4.Splitter box 4 is divided into the hollow structure in main body 3 flow passage of heat-eliminating medium.Wherein, between splitter box 4, have angle theta, its angle theta value is relevant with the quantity of splitter box 4 with the size of cooling plug, θ value scope be 0 °-be less than 90 °.On the non-working surface of main body 3, be also provided with the heat-eliminating medium outlet 2 that is no less than the heat-eliminating medium entrance 1 of and is no less than.
Aforementioned body 3 can adopt the heat conduction materials good, high temperature resistant, acid-alkali-corrosive-resisting such as cast iron, copper, graphite to make.
When use, cooling moulding of the present utility model plug is lain in a horizontal plane on forming mould, its working face 5 is near opticglass outlet pipe 6, as shown in Fig. 5-Fig. 6, heat-eliminating medium enters from heat-eliminating medium entrance 1, the cavity being isolated into by splitter box 4 by main body 3 inside arrives working face 5, with opticglass liquid 7, heat exchange occurs, and heat-eliminating medium flows out the cooling plug of moulding from heat-eliminating medium outlet 2 under pressure.
