Rotary drive mechanism for an injection molding machine

Abstract

The utility model discloses a kind of rotary drive mechanisms of injection molding machine, including turntable, first drive source and substrate, turntable is installed for forming mould, first drive source is installed on substrate, pinion is provided on the output end of first drive source, large gear is provided on the turntable and engages with pinion, multiple positioning holes are opened around circumference on the turntable, positioning column for being positioned with the positioning hole adaptive clamping is provided on the substrate, second drive source that positioning column is driven and clamped into positioning hole is provided on the substrate, power output is transmitted to turntable by the meshing of servo motor, speed reducer and pinion and large gear, the continuity of realizing turntable rotation, it can be according to actual turntable installation using the number of forming mould to control and adjust the rotation angle stop of turntable, that is, it can not stop when encountering the position without installing forming mould, and then production efficiency can be effectively improved, and have better adjustability and applicability.
