In recent years, along with the development of lanthanide optical glass, the mold temperature of glass metal is more and more higher, shaping viscosity is also more and more less, the sticking to mould frequency of glass metal also increases thereupon, and for expensive lanthanide glass, the loss caused due to sticking to mould time shaping also increases thereupon.Further, because shaping viscosity is little, the gap between plug and bed die, side form also easily carries glass metal secretly, and wire drawing etc. is abnormal to cause glass metal to occur in moulding process, and undue cooling easily causes the temperature homogeneity of mould to be deteriorated, and produces shaping striped.Therefore, existing forming mould slowly can not meet the needs of production.
Patent documentation CN 101186428A provides a kind of optical glass forming device, as shown in Figure 1, this device is made up of bed die, side form and plug, and on side form, there is flame heating device, by slowing down solidifying of glass metal to the surface heated mode of glass metal, thus the object of producing large gauge glass billot can be reached.This mode of production can solve the large gauge billot producing common optical glass preferably, also has some improvement to the R angle (upper and lower surface of glass billot and the angle of side) of billot.But, this molding mode due to component part more, owing to there is gap between each part, thermal conduction effect is poor, especially when the lanthanide optical glass that producing shaped temperature is higher, is easy to make mould to produce the high temperature of local, causes mould sticking to mould.Therefore, this mode of production die change frequency is in process of production very high, movie star's production good article rate.
Patent documentation 200610022703.X provides a kind of shaped device of fluorphosphate glass, as shown in Figure 2, is made up of described in this device bed die, side form and block, and has cooling cover plate upper, cooling cover plate has ventilating pit.This invention carries out ventilation cooling to glass surface, makes glass surface shaping as early as possible, solves the shaping striped of face that fluorphosphate glass causes because of glass surface volatilization in moulding process.But this molding mode is high in producing shaped temperature, during the low lanthanide optical glass of shaping viscosity, temperature consistency and the homogeneity at each position of mould all can not improve, and glass metal easily produces convection current striped in moulding process, thus affects production good article rate.
Above two patents are by surperficial heating or cooling, improve the R angle of optical glass strip material in moulding process and facial stripes problem respectively, but all do not solve the considerable sticking problems of glass in moulding process, especially high to mold temperature, the lanthanide optical glass that shaping viscosity is low, the problem that shaping good article rate is low is not still resolved.
