Abstract: In a moulding machine for plastics comprising an injection assembly (1) mounted slidably on a frame of the machine and a moulding assembly (30) comprising a mould half (8) mounted on a fixed plate (6) integral with the machine frame, a movement apparatus (200) for the injection assembly comprises a chain transmission (209) connected to the injection assembly (1), a drive unit (211) that drives the chain transmission (209) to move the injection assembly (1) toward the moulding assembly (30) and return means (220) connected to the injection assembly (1) to allow the injection assembly (1) to be moved away from the moulding assembly (30).

Abstract: An injection assembly for injection molding machines for plastics material comprises a fixed frame (10, 21), a plastication cylinder (2) integral with the fixed frame, a plastication screw (5) acting inside the plastication cylinder, making a forward translational movement during the stage of injection of the plastics material into a cavity of a mold and a rotatory movement around its own axis and a rotatory translational movement of rotation around its own axis and retraction during the plastics material plastication stage, the plastication screw (5) being mounted integral in translation with a movable plate (23) mounted slidably on said fixed frame, there being provided drive means for translation of the movable plate (23), and drive means for rotation of the plastication screw (5).

Abstract: A network connection system for machine tools, particularly injection presses for plastics, comprising a plurality of machine tools (1) connected to a wireless network in order to share resources and exchange data, via a radio link, between a device (12) for radio communications provided on each machine tool (1) and a server (4) equipped with the device (12) for radio communications or at least one access unit (20) connected to a hard-wired network (10, 50).
