Glass forming apparatus and method

A glass forming apparatus comprising:

• a moving mold including a plurality of curved surface-shaped cores, and configured to seat a material;
• a first forming line and a second forming line formed in parallel in opposite directions;
• each of the first forming line and the second forming line include:
• a preheating unit configured to preheat the material seated on the moving mold;
• a curved surface forming unit configured to form the material in a curved shape, wherein the curved surface forming unit includes:
• a first mold disposed to face the moving mold forming a plurality of cavities formed between the moving mold and the first mold, and
• a pneumatic device configured to generate a vacuum pressure in the plurality of cavities to adhere the material to the plurality of curved surface-shaped cores, and
• a cooling unit configured to cool the material in the curved shape transformed by the curved surface forming unit;
• a first transfer unit located at the first forming line, the first transfer unit configured to:
• move the moving mold through the preheating unit, the curved surface forming unit, and the cooling unit of the first forming line,
• move the moving mold from the cooling unit of the first forming line to the preheating unit of the second forming line, and
• supply the material to the moving mold for the second forming line;
• and
• a second transfer unit located at the second forming line, the second transfer unit configured to:
• move the moving mold through the preheating unit, the curved surface forming unit, and the cooling unit of the second forming line,
• move the moving mold from the cooling unit of the second forming line to the preheating unit of the first forming line, and
• supply the material to the moving mold for the first forming line.
