Abstract
A drive arrangement for an injection molding machine (1) embodies a linear drive (5,10,11) for moving and/or locking mold mounting plates (2,3), or rather the molds mounted thereon. The linear drive is provided with at least one toothed rack (5) which on the drive output side is in direct functional connection with the mold mounting plate (3), and on the drive input side presents series of teeth (12a,12b) that mesh with at least one drive gearwheel (16,17).
Claims17
A molding machine comprising a base frame, two mold plates mounted on said base frame for relative movement between a mold open position and a mold closed position, and linear drive means mounted on said base frame and operable to move at least one of said mold plates, said linear drive means comprising at least one servomotor, at least one set of gears driven by said servomotor, and a toothed rack connected to said at least one mold plate said toothed rack having opposed series of teeth, one series of teeth in mesh with at least one gear of said set of gears, another gear opposed to said one gear and in mesh with the other series of teeth, and means for supporting said toothed rack whereby the rack and said at least one mold plate are driven in operation of the servomotor.
A drive arrangement for a molding machine, said molding machine comprising a base frame, and two mold plates mounted on said base frame for relative movement between a mold open position and a mold closed position, said drive arrangement comprising linear drive means mounted on said base frame and operable to move at least one of said mold plates, said linear drive means comprising at least one servomotor, at lest one set of gears driven by said servomotor, and a toothed rack connected to said at lest one mold plate said toothed rack having opposed series of teeth, one series of teeth in a mesh with at least one gear of said set of gears, another gear opposed to said one gear and in mesh with the other series of teeth, and spaced bearings supporting said toothed rack whereby the rack and said at least one mold plate are driven in operation of the servomotor.
