METHOD FOR MANUFACTURING GLASS PLATE, AND APPARATUS FOR MOLDING GLASS PLATE

To provide a technique capable of improving the surface accuracy of a glass plate after molding.SOLUTION: A method for manufacturing a glass plate including a first main surface and a second main surface facing the first main surface and including curved surfaces in the first and second main surfaces comprises: installing the glass plate so as to face the first main surface of the glass plate to a lower die including a curved surface; installing a pressing part so as to face the second main surface of the glass plate supported by the lower die; and heating the glass plate. The pressing part liftable and installed only in a part of the second main surface and installed in the peripheral part of the second main surface presses the second main surface by the weight of the pressing part and is in the state of pressing only the part of the second main surface and the peripheral part thereof during the heating.SELECTED DRAWING: Figure 3 【課題】成形後のガラス板の面精度を向上する、技術を提供する。【解決手段】本開示におけるガラス板の製造方法は、第１主面と前記第１主面とは反対向きの第２主面とを含み、前記第１主面と前記第２主面に曲面を含む、ガラス板の製造方法であって、前記ガラス板の前記第１主面が曲面を含む下型に向かい合うように、前記ガラス板を設置することと、前記下型で支持されている前記ガラス板の前記第２主面に向かい合うように、押さえ部を設置することと、前記ガラス板を加熱することと、を有し、前記押さえ部は、昇降自在であって、前記第２主面の一部のみに設置され且つ前記第２主面の周縁部に設置され、前記押さえ部の重さで前記第２主面を押さえ、前記加熱の際には、前記第２主面の一部のみかつ周縁部を押さえた状態である、ガラス板の製造方法に関する。【選択図】図３
