US 10,518,448 B2 · Additional injection modular system

Abstract

Additional injection modular system applicable in any process for molding parts or products by polymer injection is provided, wherein injecting one or more parts or products with a single material or a plurality of polymer materials requiring separate, simultaneous or sequential complementary injections becomes necessary in addition to the injection of a base material processed in a conventional injection machine. The system has a module configurable in both composition and dimension with optimized rheological and energy behavior which is installed between the closure assembly plates of the base machine and the mold, comprising a frame, front mold clamping plate, structure clamping plate, structure spacer blocks, at least one additional injection assembly, at least one additional injection nozzle and injection nozzle extension. The system herein can be used in the production of parts by injection processes generally designated as multi-component injection.

Dependent claims

A modular system for providing additional injection units for an injection machine, the modular system comprising:

a first clamping plate adapted to be coupled to an injection machine, on one of a stationary plate of an injection machine and a movable plate of the injection machine;
a second clamping plate adapted to be coupled to a mold;
an injection nozzle extension having a first end and a second end, wherein:
the first end is disposed on the first clamping plate and is adapted to be coupled to the injection machine and to receive a first material from the injection machine and allow the first material to pass through the injection nozzle to the second end;
and
the second end is disposed on the second clamping plate and is adapted to be coupled to an inlet of the mold and to inject the first material into the mold;
and
an additional assembly disposed between the first clamping plate and the second clamping plate, the additional assembly being coupled to the first clamping plate, the additional assembly comprising at least one second nozzle adapted to inject at least one second material into the mold.
