According to the method, the molten metal is used for uniformly applying pressure to the glass preform in the forming die 200, so that the pressure born by the glass preform in each direction in the softening and deformation process is the same, and a more complex glass element can be formed under the condition that the thickness of the glass preform is uniform; meanwhile, the power mechanism 300 can control the pressure born by the glass preform in the deformation process, so that the forming precision of the glass element is improved.
Further, as shown in fig. 3, the molding die 200 includes: a lower mold 210 and an upper mold 220 fitted to the lower mold 210, and a glass preform is fixed between the lower mold 210 and the upper mold 220. The cavity comprises an injection cavity 211 arranged on the lower die 210 and a cavity 221 arranged on the upper die 220, the cavity 221 is opposite to the injection cavity 212, and the cavity 221 is used for providing a forming space for forming the glass preform; a feed inlet 211 is opened to lower mould 210, and pipeline 400 passes through feed inlet 211 and pours into the chamber 212 intercommunication into, pours into the chamber 212 and is used for holding the molten metal into, pours into the both sides of chamber 212 and is equipped with platform portion 213, and platform portion 213 place height is less than the upper surface place height of lower mould 210, and platform portion 213 is used for placing the glass perform.
This application is through setting up the platform portion 213 that highly is less than lower mould 210 upper surface place height for place the glass preform, can guarantee that the glass preform places stability.
It should be noted that: to ensure the precision of the molded glass member, the opening width of the cavity 221 is smaller than the opening width of the injection cavity 212.
