Abstract

A description is given of a plasticizing unit for an injecting unit of an injection-moulding machine, having a carrying element arranged beneath the cylinder and connected thereto. In order to simplify the adjustment of the nozzle centre, the invention provides a fixing element which encloses that end of the carrying element which is directed away from the cylinder such that there is a spacing present between the fixing element and the carrying element. A plurality of adjustment elements are provided between the fixing element and the carrying element, said adjustment elements being designed to establish a force-fitting and / or form-fitting connection between the fixing element and the carrying element and to be able to adjust the position of the carrying element relative to the fixing element in a plane orthogonal to the cylinder axis. The plasticizing unit can be secured in, and released from, a clamping and positioning system, the latter being connected to the machine bed, by way ofits fixing element. For changeover of the plasticizing unit, an adjustment of the nozzle centre, once made, is maintained because the plasticizing unit is removed, and installed, together with the fixing element.

Description

technical field [0001] The invention relates to a plasticizing unit for an injection unit of an injection molding machine, the plasticizing unit having a cylinder and a screw rotatable in the cylinder and movable in the axial direction. Background technique [0002] In an injection molding machine it may be necessary to replace the plasticizing unit from time to time. An injection molding machine with an exchangeable plasticizing unit is known from DE 3637885 A1. In order to minimize the conversion time, a preheating station is provided in which the plasticizing unit is connected to the supply connection and can be preheated under operating conditions. For fast and preferably automatic fastening or loosening of the plasticizing unit in the injection station or in the preheating station, a cavity-shaped receptacle and a clamping device with wedges are respectively provided, The wedges cooperate axially and radially with corresponding wedge surfaces on the plasticizing unit....
