Abstract
The invention pertains to an injection molding machine comprising, an injection nozzle (2) having a melt channel (6), an injection opening (5), and a filter (9) for filtering the molten resin within the injection nozzle (2). According to the invention, the melt filter (9) cooperates with the 5 melt channel (6) or a means (7) provided within the melt channel (6) in such a way, that during an injection phase of the injection molding machine, the molten resin is caused to pass through the filter (9), and during a decompression phase of the injection molding machine the molten resin is caused to bypass the filter (9).
Claims20
An injection molding machine comprising:
- an injection nozzle having a melt channel,
- an injection opening, an inlet port for a molten resin and
- a filter for filtering the molten resin within the injection nozzle, wherein
- the filter is configured to cooperate with the melt channel for molten resin or a means arranged within the melt channel, such that during an injection phase of the injection molding machine, the molten resin is caused to flow through the filter and during a decompression phase of the injection molding machine, the molten material is caused to bypass the filter
- wherein the filter is of an annular design and arranged, such that it divides the melt channel into a cylindrical section within the filter and an annular section outside the filter, the annular section outside the filter communicates with the injection opening and the filter is displaceable into a decompression position in which the stops of the filter and of the means for guiding the molten resin which face the injection opening are spaced from each other and provide a passage for the molten resin from the annular section outside the filter into the cylindrical section within the filter.
