System for heating and cooling of galvanically produced tool for production of surface-area structured plastic molded skin, has inlet and drain switching distributors, heating device and heat reduction device connected with tool

摘要

The system (10) has inlet valves (18.1-18.9) arranged upstream to heat accumulator units (W1-W8) in inlet lines (14.1-14.9) and drain valves (20.1-20.9) arranged downstream to the accumulator units in drain lines (16.1-16.9). The accumulator units comprise heat accumulator medium i.e. oil. The inlet and drain lines are connected with an inlet and drain switching distributors (22, 24), respectively. The distributors are connected with a tool (12) via an advance line (26) and a return line (28), respectively. A heating device (38) and a heat reduction device (36) are connected with the tool.
