Abstract
The invention relates to an ejector unit for the electrically-driven ejection of injection moulded pieces from injection moulds. According to the invention, the above may be achieved by the interposing of an elliptical gear drive. The elliptical gear drive can be arranged outside the driving means for the moving mould, which gives more space in the central region of the moving mould for an improved usage with the driving means thereof. The elliptical gearwheel drive has very similar gearing characteristics to a crank, however, with more precise limitation of the force on the driveshaft. Thus the advantages of a crank drive for the ejector unit can be used, with a greater saving of space in the valuable central region of the drive side of the moving mould.
