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.

A molding system includes a mold and a fluid delivery system. The mold includes a fluid permeable material that defines a mold cavity and is permeable to a cooling fluid. The mold is configured to mold a molten material arranged in the mold cavity. The fluid delivery system is in fluid communication with the fluid permeable material, and is configured to deliver the cooling fluid via nozzles to the fluid permeable material. When the molten material is arranged in the mold cavity, the fluid delivery system delivers the cooling fluid to the fluid permeable material at a delivery pressure that is intentionally varied, such that the cooling fluid permeates through the fluid permeable material to cool and solidify the molten material arranged in the mold cavity to form a solidified outer skin. The delivery pressure may be varied, e.g. increased, as a thickness of the solidified outer skin increases.

The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process.

A production method for producing cast parts from metal using a sand casting mold (1). The sand casting mold (1) is produced in this case in a molding box (2) by means of a negative-pressure molding method. According to the invention, the sand casting mold (1), which is under negative pressure, in the molding box (2) is first of all filled with molten metal (5). The molding box (2) with the sand casting mold (1), which is under negative pressure therein, is then completely or partially impinged upon by a cooling fluid (4) and after, at the same time as, or before the cooling fluid impingement is opened at places with cooling fluid impingement. As a result of this, cooling fluid (4) is sucked into the sand casting mold (1) which is under negative pressure, as a result of which the solidifying cast part (3) is quenched more quickly.
