Water isolation device and method for core-pulling spraying water of die-casting mold

The invention discloses a water insulation device and method for die-casting die core-pulling water spraying, and belongs to the technical field of high-pressure casting, the water insulation device comprises a water insulation unit and a driving component, the water insulation unit is arranged on a first die corresponding to a core-pulling tailstock, and the end face, facing the core-pulling tailstock, of the water insulation unit is provided with a blocking plane; the blocking plane is in sliding fit with the side wall face, deviating from the first mold, of the core-pulling tailstock and shields the area, located on the core-pulling tailstock, of the gap. And the driving components are arranged between the first mold and the water isolation unit. The invention further discloses a water insulation method for core-pulling spraying water of the die-casting mold. The invention provides a die-casting mold core-pulling water spraying waterproof device and method which can be suitable for a core-pulling tailstock
