Paper Abstract

With the booming of the curved glass shell and curved panel on the smart phone, the development of 3D curved glass molding process, mold and equipment are fairly promoted. This paper introduces a self-developed full-motor-driving precision molding machine’s developing course. Seven different molding stations using electric actuators as molding axes devices are designed in molding chamber to gives good production efficiency and adaptation of complex process to the molding machine. The maximum molding force and the highest molding temperature is up to 5000N and 800oC, respectively, which satisfies different production requirements. The control unit is built based on the industrial computer in the console and consists of two parts: numerical control system and temperature control system. The control unit can control the molding speed, depth, time directly while the molding force and temperature are controlled by the mean of feedback system. A 3D curved glass molding experiment is carried out by using the machine and graphite mold and finally the 3D curved glass is produced. This result shows that the precision molding machine has achieved the designed functions to manufacture the 3D curved glass and other different complex optical components.
