Abstract:
An injection-molding unit for an injection-molding machine to process plastics and other plasticizable compounds, the unit comprising:a carrier block to hold a plasticizing cylinder, a conveyor arranged in the plasticizing cylinder along a injection axis to inject the plasticizable compound into a mold, an injection bridge that moves axially along the injection axis, on which the conveyor is rotatably mounted with at least one bearing element, an electromechanical injection unit to move the injection bridge axially, wherein a means of linear movement of the injection unit is rotatably mounted on the injection bridge via at least one bearing element, a support to support the element that works with the means of linear movement so that the element cannot turn, an injection motor, which turns the means of linear movement by means of a first drive element coaxial to the means of linear movement, an electromechanical rotary motor, which turns the conveyor by means of another drive element coaxial to the conveyor and also to the first drive element, force-transmission elements that have at least one axial bearing element, for transmitting the axial movement of the means of linear movement to the conveyor, characterized by the fact that the axial bearing element is arranged directly between the first drive element and the other drive element as a force-transmission element.
