Abstract
System for cooling molds for metals, having one or more main conduits, each for transporting a main flow of a cooling carrier fluid containing compressed air and nebulized water, and a plurality of secondary conduits connected to and originating from the main conduit. The free end of each secondary conduit is susceptible of being inserted into a corresponding channel of a duct made in one of the half-molds of a mold. The main conduit is provided with a shaped closed terminal portion for distributing, into the secondary conduits that radially depart therefrom, substantially equal secondary flows of the cooling carrier fluid, injecting them through the free ends thereof into the corresponding channels of each half-mold.
Claims17
Cooling system for cooling molds for metals or for metal alloys provided with at least two shaped half-molds, that are coupled together in order to define a molding chamber adapted to contain melted metal material, such cooling system comprising:
- at least one main conduit for transporting a main flow of a cooling carrier fluid containing compressed air and nebulized water, having a first transport section (S1);
- a plurality of secondary conduits connected to and originating from said at least one main conduit and each provided with a second transport section (S2) smaller than the first transport section (S1) of said at least one main conduit and with a free end susceptible of being inserted in a corresponding channel of a duct made in one of said at least two half-molds;
- wherein said at least one main conduit is provided with at least one closed terminal portion, which is radially and peripherally connected to three or more of said secondary conduits;
- said at least one closed terminal portion being shaped for distributing in said secondary conduits substantially equal secondary flows of said cooling carrier fluid, injecting said secondary flows through the free end thereof into said corresponding channel of a duct made in one of said at least two half-molds;
- wherein said cooling system further comprises:
- means for feeding a compressed air flow;
- means for feeding a water flow;
- and
- means for mixing said water flow in said air flow comprising at least one nebulization nozzle in order to nebulize said water flow in said air flow, producing said cooling carrier fluid which feeds said at least one main conduit.
Cooling system for cooling molds for metals or for metal alloys provided with at least two shaped half-molds, that are coupled together in order to define a molding chamber adapted to contain melted metal material, such system comprising:
- at least one main conduit for transporting a main flow of a cooling carrier fluid containing compressed air and nebulized water, having a first transport section (S1);
- a plurality of secondary conduits connected to and originating from said at least one main conduit and each provided with a second transport section (S2) smaller than the first transport section (S1) of said at least one main conduit and with a free end susceptible of being inserted in a corresponding channel of a duct made in one of said at least two half-molds;
- wherein said at least one main conduit is provided with at least one closed terminal portion, which is radially and peripherally connected to three or more of said secondary conduits;
- said at least one closed terminal portion being shaped for distributing in said secondary conduits substantially equal secondary flows of said cooling carrier fluid, injecting said secondary flows through the free end thereof into said corresponding channel of said at least two half-molds;
- wherein said at least one closed terminal portion of said at least one main conduit is provided with second through holes, each hydraulically connected to a corresponding said secondary conduit peripherally fixed to said at least one closed terminal portion;
- said second through holes being made at a distribution circumference of a transverse section of said at least one closed terminal portion.
