Drive apparatus for injection molding machine, injection apparatus, and mold clamping apparatus

摘要

An object is to provide a mold clamping apparatus for an injection molding machine which can generate a large thrust force and can provide short-cycled continuous drive. The drive apparatus includes a housing; a tubular linear motor (214) including a movable element (212) disposed in a manner capable of advancing and retreating, and a stationary element (213), the linear motor (214) serving as a first drive section; a member-to-be-driven (256) caused to advance and retreat together with the movable element (212); and a second drive section (276,286) and disposed such that at least a portion of the second drive section overlaps the linear motor (214) at the interior thereof.
