Finite element model of ultraprecision glass molding press for micro aspherical glass lenses is built by the nonlinear finite element software MSC.Marc. Numerical simulation analysis is carried out. Compared to residual stress of formed lens and mould distribution under the different processing parameters, the optimal molding velocity and the range of molding temperature of ultraprecision glass molding press are obtained. The research results are helpful for the mass production of micro aspherical glass lenses.
