Abstract
The invention relates to a device for cooling a casting mold (14), comprising an evaporation chamber (18) formed in the casting mold (14), a first pump (23) for supplying a liquid to the evaporation chamber (18), and a second pump (30, 31) for applying a pressure in the evaporation chamber (18), which differs from the atmospheric pressure. The invention also relates to a corresponding method. The invention allows the cooling of a casting mold to be controlled in a targeted manner. This can be helpful in particular in the injection molding of plastic parts.
Claims18
A device for cooling a casting mold (14), having an evaporation chamber (18) formed in the casting mold (14), a first pump (23) for supplying a liquid to the evaporation chamber (18), and a second pump (30, 31) for applying a pressure in the evaporation chamber (18) which differs from atmospheric pressure, an inlet line (19) which extends to the evaporation chamber (18), wherein the liquid in the inlet line (19) is put under an increased pressure, with the result that the liquid does not evaporate in the inlet line (19), wherein the first pump (23) is designed to deliver the liquid at said increased pressure through the inlet line (19), and wherein a section of the inlet line (19) which is adjacent to the evaporation chamber (18) forms a local constriction in the inlet line (19).
A method for cooling a casting mold (14), in which a liquid is supplied through an inlet line (19) to an evaporation chamber (18) formed in the casting mold (14) in order to evaporate the liquid in the evaporation chamber (18), and in which a pressure which differs from atmospheric pressure is applied in the evaporation chamber (18), wherein the liquid in an inlet line (19) leading to the evaporation chamber (18) is put under an in-creased pressure, with the result that the liquid does not evaporate in the inlet line (19), and a section of the inlet line (19) which is adjacent to the evaporation chamber (18) forms a local constriction in the inlet line (19).
