Injection molding machine servo turntable control device

The utility model belongs to the field of injection molding, and particularly relates to a servo turntable control device of an injection molding machine. The utility model provides an electric turntable which adopts servo drive to drive a servo motor, and the servo motor directly drives the turntable through a mechanical gear. The servo motor adopts an absolute value encoder, the current positionof the turntable can be monitored in real time, and the servo drive outputs an S-shaped flexible speed curve through position operation, so that the turntable can rotate quickly and stably, and the conditions of oil leakage and the like are avoided. And the reliability of the machine is greatly improved. The technical scheme adopted by the utility model is as follows: the servo turntable controldevice of the injection molding machine comprises a mold and an upper control machine, and further comprises a mold changing turntable clamped with the mold; the servo motor is meshed with the die changing turntable; the servo
