发明名称 Glass forming apparatus and glass forming method
摘要 A glass forming apparatus and a glass forming method of high economical merit and high production efficiency are provided. More specifically, the glass forming apparatus has dies, in which at least one die is divided into a heat exchange unit and a press unit, and in the glass forming apparatus and glass forming method, the plane precision is improved in the contact dividing surfaces of the heat exchange unit and the press unit. A glass forming apparatus includes a die having a press surface for pressing a glass material, in which the die has a plurality of dies, and at least one die is divided into a heat exchange unit and a press unit. Preferably, the surface precision of at least one part of each dividing surface in contact with the heat exchange unit and the press unit has a flatness (PV) of 500 mum or less, and the plane precision of at least one part of the dividing surface has a surface roughness (Ra) of 100 mum or less.
