AI Technical Summary

Technical Problem

Existing injection molding systems with electric motors for controlling valve needles are costly, complex, and require separate electronic control units, increasing equipment costs and dimensions.

Method used

The supply and control unit is integrated with the mounting plate, eliminating the need for a separate electronic control unit by using brushless rotary electric motors with encoders or resolvers, and allowing manual or remote configuration of parameters via a control panel.

Benefits of technology

This integration reduces costs and dimensions while maintaining control flexibility, simplifying structure and cleaning, and eliminating hydraulic/pneumatic connections.

Abstract

Device for injection molding of plastic materials, comprising a mold (4) and a machine mounting plate (13) for connection to an injection molding machine (7) providing the plastic material in a liquid state, wherein the mold (4) comprises the following: a distributor (6) of the plastic material to be injected, comprising at least one injector (8) and a nozzle (9) with respect to which a valve needle (10) is movable, at least one electric actuator (15) for controlling the displacement of the valve needle (10) between a closed and an open position to allow the flow of pressurized liquid plastic material from the distributor (6) to the mold cavity (5) of the mold (4), a supply and control unit (22) for supplying and controlling the at least one respective electric actuator (15), wherein the supply and control unit (22) is equipped with at least one electronic control board (26) for configuring the main parameters for opening and closing each injector (8) assigned to each electric actuator (15), and a mounting plate (12) for attaching the mold (4) to the machine mounting plate (13), wherein the mounting plate has a cavity (11) for receiving the distributor (6) and a seat (20) for receiving the electric actuator (15) and wherein the supply and control unit (22) is attached to the mounting plate (12) and is uniquely assigned to the mounting plate (12).
