Abstract
A multi-mold block drive device includes a guide seat and a plurality of speed reductions units. The guide seat includes opposite inner and outer peripheral surfaces, and a plurality of spaced-apart guide holes extending through the inner and outer peripheral surfaces. A plurality of drivers correspond respectively to the guide holes. Each speed reduction unit is connected between one of the guide holes and a corresponding driver, and includes a guide screw rod having an externally threaded portion, a guide sleeve having an internal thread facing the externally threaded portion, and a plurality of planetary screws interposed between the guide screw rod and the guide sleeve. Each planetary screw has a drive thread meshing with the externally threaded portion and the internal thread. An injection molding machine having the multi-mold block drive device is also disclosed.
