Seal monitoring arrangement especially for use in monitoring the sealing of an arrangement for producing molded parts using plastic injection molding, is based on use of flow monitoring rather pressure monitoring

摘要

Arrangement for monitoring the sealing of a sealing element (2) that surrounds a pressure chamber supplied from a pressure source (4) over a filling line (3). A monitoring line (9) is arranged in parallel to the filling line and incorporates a flow monitor (12) with a signal switch that generates a signal if a flow is detected through the monitoring line.
