INJECTION MOLDING MACHINE DRIVING DEVICE, INJECTION DEVICE AND MOLD CLAMPING DEVICE |
摘要 |
<p>An object is to provide a drive 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 (11); a tubular linear motor (14) including a movable element (12) disposed within the housing (11) in a manner capable of advancing and retreating, and a stationary element (13) attached to the housing (11), the linear motor (14) serving as a first drive section; a member-to-be-driven (15) caused to advance and retreat together with the movable element (12); and a second drive section attached to the housing (11) and disposed such that at least a portion of the second drive section overlaps the linear motor (14) along the axial direction. By merely a slight increase in a radial dimension, the area of a permanent magnet (23) of the movable element (12) can be sufficiently increased, and the capacity of the linear motor (14) can be increased. <IMAGE></p> |
