Abstract

A machine frame with a displaceable scaffold for a tool space of an injection molding machine with stationary and movable tool clamping plates connected by columns that are adjusted to a tool height with a tool height adjusting device, the machine frame being formed with a stepped profile for lowering of the center of gravity of the movable tool clamping plate, the slide carriage of the movable tool clamping plate being displaceable on lower straps formed as guideways, and the displaceable scaffold being displaceable on the inner straps of the machine frame and the slide carriage, and being connected with the tool height adjusting device by connecting rods, the displaceable scaffold being shifted under the stationary tool clamping plate when the forming tool is closed.
