Die particularly for on-road vehicle wheels

Abstract

A die particularly for on-road vehicle wheels, of the type that comprises lower, upper and lateral die parts that form an impression to be filled with molten material, comprising at least two die filling points arranged at two openings of the design of a wheel where the lower die part and the upper die part are in contact when the die is in the closed configuration.

         10 . A die particularly for on-road vehicle wheels, of the type that comprises lower, upper and lateral die parts that form an impression to be filled with molten material, comprising at least two die filling points arranged at two openings of the design of a wheel where the lower die part and the upper die part are in contact when the die is in the closed configuration.  
     
     
         11 . The die of  claim 10 , wherein at said filling points said lower and upper die parts are shaped so as to form passages for the molten material.  
     
     
         12 . The die of  claim 10 , wherein said lower die part is arranged above a furnace and is provided with through holes, at said filling points, for the passage of the molten material that arrives from ducts connected to said furnace.  
     
     
         13 . The die of  claim 12 , wherein said ducts are constituted by risers, one for each through hole, which are fed by said furnace.  
     
     
         14 . The die of  claim 12 , wherein said ducts are constituted by channels, one for each through hole, that protrude from a common riser fed by said furnace.  
     
     
         15 . The die of  claim 14 , wherein said channels lie radially starting from an upper end of said common riser, which is arranged in a substantially central region below said die, with an end portion that is substantially vertical and ends at said through holes of the lower die part.  
     
     
         16 . The die of  claim 12 , wherein said upper die part has, above said through holes of the lower die part, cavities that allow the inflow of the molten material that arrives from said ducts into the impression formed between the two die parts with the die in the closed configuration.  
     
     
         17 . The die of  claim 16 , wherein said cavities are substantially radial with respect to the wheel, forming inlets for the molten material at the center and at the outer rim of said wheel.  
     
     
         18 . The die of  claim 17 , wherein said upper die part has redirection elements for the molten material at said cavities, above said through holes of the lower die part.
