PRE-HEATING DEVICE OF CURVED GLASS MOULDING DEVICE

摘要

The present invention relates to a preheating device of a glass molding machine having a curved surface, and more specifically, to a preheating device of a glass molding machine having a curved surface, which can prevent a material from being damaged by preventing weight application to a mold as equipped with a preheating means preheating while being in contact with the mold in an unloaded state, and can reduce a cycle time required in glass molding having a curved surface since the mold can be quickly increased to a preheating temperature.
