Appts. for cleaning moulding tools used to produce sand cores and masks - having handling units for transporting tool parts through various cleaning stations.

摘要

Moulding tools used in core shooting machines are uncoupled from the machine and transported on a device (6) to a first mixing device (7), at least one ultrasonic bath (8), a second rinsing device (9), a cooling device (10), a drying unit (12) and final via a further transporter (14) back to the core shooting machine or into store (5). Handling units are present to place the tools into the various baths or units. The transporter (6) is a roller conveyor. The first handling unit acts to disconnect the tool upper part with the ejection plate (2) from the tool lower part. The rinsing device is a bath with a holding unit for supporting the tool set. Water is sprayed from nozzles and recycled via collection bath. The ultrasonic bath consists of a bath with a holding unit. The bath contains a leaching solution. The cooling bath has holder and is circulated with coolant water. ADVANTAGE - The food cleaning process becomes rapid and fully automatic.
