Integrated pre-heating and cooling system for dies

摘要

The invention concerns a system for the thermoregulation of dies for die-casting, dies for chill casting and the like. It comprises a tank (11) containing a cooling fluid; a primary hydraulic circuit (12) for a circulation of the cooling fluid from the tank to the die to be cooled and from this to the tank through a heat exchanger (SC); a secondary pneumatic circuit (13) connected to the primary hydraulic circuit (12) for the circulation of an aeriform fluid in the die to be cooled both in alternative, and in a mixed form with the liquid cooling fluid; and a pre-heating hydraulic circuit (112) integrated with the primary hydraulic circuit (12) and assigned to the production and circulation of a hot liquid fluid for pre-heating the die to be thermoregulated.

1. A system, for the thermoregulation of a die, comprising
an open tank (11) containing a liquid cooling fluid, a primary hydraulic circuit (12) for a circulation of said liquid cooling fluid from said open tank to the die and from the die to the open tank through a heat exchanger (SC), a secondary pneumatic circuit (13) connected to the primary hydraulic circuit (12) and provided for the circulation of an aeriform fluid in the die to be cooled both in alternative, and in a mixed form with the liquid cooling fluid, and a control unit of the primary hydraulic circuit (12) and of the secondary pneumatic circuit (13) to operate the cooling of the die with only the liquid cooling fluid, with only the aeriform fluid or with the aeriform fluid mixed with liquid fluid, further comprising a pre-heating hydraulic circuit (112) integrated with the primary hydraulic circuit (12) and assigned to the production and circulation of a hot liquid fluid for pre-heating the die.
