Abstract
A multi-mold block drive device includes a guide seat having a plurality of spaced-apart guide holes extending through inner and outer peripheral surfaces thereof, a plurality of speed reduction drive units each including a speed reducer driven by a servo motor and having an eccentric shaft, and a plurality of mold locking units each connected between one of the guide holes and a corresponding speed reduction drive unit. Each mold locking unit includes a pivot shaft, a linkage disposed between the pivot shaft and the corresponding guide hole, and a guide rod pivoted to the linkage. The linkage includes a crank driven by the eccentric shaft, a first link arm pivoted between the crank and the pivot shaft, and a second link arm pivoted between the crank and the guide rod. An injection molding machine having the multi-mold block drive device is also disclosed.
