Influences of models shape on molding time in glass molding press
Optical glass is widely used as the most important material in optical field in recent years.Glass molding press (GMP) has been employed as a promising technique to manufacture optical components in mass production.Heating time and annealing time are the key factors which influence the production cycle.In this paper,an effective method of improving the heating or the annealing effectiveness is to increase the area exposed to the cooling or hot nitrogen by means of adding slots.In the same condition,four models with different slots were built.Based on the theoretical analysis of glass heating and annealing property in the molding process,finite element simulation was carried out.The results showed that the model with slots may decrease the heating and annealing time.
