Problems solved by technology
In order to overcome this problem, the technology of manufacturing curved glass using vacuum adsorption and heat has been developed, but the heat applied to the mold cannot be effectively controlled resulting in product errors
[0005] According to conventional technology, the mold unit with a single cavity is allowed to pass between the upper heater unit and the lower heater unit, so the production volume of curved glass is not high
In addition, when a plurality of mold units are arranged in parallel, there is a problem that the molding quality of the glass is not uniform due to the temperature difference between the end and the center of each heater unit

A device for molding a glass curved surface, according to the present invention, comprises: a plurality of mold units formed in a chamber for thermomolding and including a lower mold, which has one or more cavities such that each of the cavities is injected with glass, and an upper mold corresponding to the shape of glass, to be processed, and arranged on the upper side of the lower mold; and first and second process parts respectively including an injection part for injecting the plurality of mold units, a preheating part for increasing the temperature of the glass, a molding part for molding the glass, a cooling part for cooling the glass molded by the molding part and a discharge part for discharging the glass cooled by the cooling part, wherein the molding part can gradually decrease the increase rate of the heat applied to the plurality of mold units from the injection part side to the cooling part side.
Description
technical field [0001] The device and method according to the present invention relate to a device for forming a curved glass and a method for forming a curved glass using the device, more particularly, to: a device for forming a curved glass and a method for forming a curved glass using the device, so that A plurality of mold units on which flat glass is placed is placed in a hot chamber, and then the glass is formed with a curved surface by vacuum suction or pressing. Background technique [0002] Electronic devices such as mobile phones and digital cameras use liquid crystal display devices or organic light emitting diode (OLED) display devices to allow users to display display units. In front of the display device, a transparent window glass is formed. [0003] Recently, as portable devices having curved surfaces have been developed, demands for windows including curved surfaces have been increasing. In general, curved glass products applied to various electronic produ...
