Method for the controlled cooling of castings in sand moulds, particularly vacuum-compacted sand moulds, and apparatus for carrying out the method

摘要

The cooling of castings in sand moulds, particularly in vacuum-compacted sand moulds (4), is accelerated by passing a coolant through the mould. The coolant is conducted through a system of cooling pipes (5) or introduced through it directly into the sand mould (4). Direct passage of the coolant into the sand mould (4) is also possible by means of a system of injector nozzles.
