Embodiment Construction

[0021] A movable mold mounting plate 11 is shown in the respective figures, which has a hole 13 when only one ejector rod 24 is used.

[0022] In addition, a threaded shaft 21 is shown in all figures, in which a toothed wheel 22 is fastened on one end face. The gear 22 here has an outer diameter D which is greater than the outer diameter d of the spindle 22 (see FIG. 2 ).

[0023] The spindle is associated with an engaging element 40 which is either designed as a spindle nut 41 or is formed by a sliding element 42 .

[0024] The teeth of the gear 22 mesh with the internal teeth of the tubular member 31 . Here the gear 22 can move freely in the lateral direction, and can rotate under force in the radial direction.

[0025] The tubular member 31 can be connected with the rotor 32 of the hollow shaft motor 43 , and can also be connected with the output gear of the driving motor 62 through the teeth 33 .

[0026] The drive units are each surrounded by a housing 51 .

Abstract

A device for the removal of plastic injection moldings from the mold of an injection molding machine having movable and fixed die chucking plates includes a drive unit for moving an actuating element toward or away from the mold. The actuating element is connected to a spindle mounted in an engagement component. One end of the spindle is connected to a toothed disk. A tubular component is mated with the toothed disk so that the toothed disk is fixed with respect to rotation relative to the tubular disk and is axially movable therein. The tubular component is rotatable by the drive unit for effecting the axial displacement of the actuating element.

Description

technical field [0001] The invention relates to a device for removing injection molded parts from a mold of an injection molding machine, in particular for plastics, having a movable and a fixed mold mounting plate, said device having a drive unit, Via the drive unit, the operating element can be moved linearly towards or away from the mold. Background technique [0002] Known by EP0724944 is a kind of ejection unit, wherein has a servo motor fixed on the movable mold mounting plate, a stator and a rotor, on the rotor a hollow shaft is fixed, it has a ball screw nut, ball screw It can be used to move forward and backward. [0003] An ejector unit for an injection molding machine is known from GB29722964, wherein the screw shaft is rigidly connected to the ejector plate and has a nut which can be rotated by an electric motor. [0004] The design of the ball screw nut is disadvantageously limited in the above-mentioned ejector unit, since it, together with the hollow shaft, ...
