Problems solved by technology

[0011] The overall size of the unit fixed to the mold 1 may in some cases cause problems during the steps of transport and installation in a dedicated molding machine
[0012] Furthermore, there is no advantage in terms of the operator's time, considering that the need to configure the main parameters to properly control the circuit board driver 5 still arises before starting the molding process

Embodiment Construction

[0023] exist image 3 and 4 In all two embodiments of the invention exemplified in, one part of the power supply and control unit 3 (in particular at least one part of the particular memory 4 or 6) is fixed to the mould 1, while the other part of the power supply and control unit 3 ( In particular the control drive 5) of the motor of the obturator of the syringe is provided outside the mould 1.

[0024] according to image 3 In the first embodiment of the invention illustrated in , the driver 5 can be inserted into a box separate from the mould 1 , eg a moulding press 2 fixed to the moulding apparatus.

[0025] In particular, all moulds that use electric motors for displacing the obturator already provide a safety interface box to be combined with the moulding press. Thus, the drive 5 can be inserted into the safety interface box or into another separate box.

[0026] Alternatively, the moulding press 2 of the apparatus can be provided directly with a drive 5 integrated in...

Abstract

An apparatus for injection molding of plastic materials includes a mold (1), at least one injector having a valve pin actuated by an electric motor, and a supply and control unit (3) of the electric motor. The supply and control unit includes a memory (4) and remote control drivers (5) of the electric motor operatively connected to the memory. At least one part of the memory (4; 6) is separated from the drivers (5) arranged at a remote position with respect to the mold (1), and is fixed to the mold (1).

Description

technical field [0001] The present invention relates to an apparatus for injection moulding of plastics material, comprising: a mould comprising a dispenser of the plastics material to be injected; at least one syringe comprising a nozzle about which a valve pin is movable; and an actuator Means for controlling the displacement of the valve pin between closed and open positions to enable flow of pressurized fluid plastic material from the dispenser to the mold cavity. Background technique [0002] Traditionally, the actuator means used to control the valve pins of the injectors or each injector consisted of: fluid actuators, which due to the provision of dedicated systems and piping for supplying oil and gas and almost zero control other than on / off actuation The need for options necessitates considerable complexity. Furthermore, there are issues related to cleaning and the overall size due to the presence of the pipes. [0003] An electric motor, especially of the rotary ...
