Description

technical field [0001] The invention belongs to the technical field of automobile engines, in particular to a device and method for rapidly cooling the temperature of a high-silicon aluminum alloy engine block die-casting mold. Background technique [0002] Die-casting mold temperature has a great influence on the quality of die-casting parts. Excessively high mold temperature will cause shrinkage porosity and even shrinkage cavity defects in the die-casting part. Die-casting mold temperature that meets the process requirements is the prerequisite for obtaining qualified die-casting parts. The cooling of the die-casting mold is an effective means to ensure that the mold temperature is within a suitable temperature range. At present, the cooling methods of the die-casting mold are mainly water cooling and air cooling, but these two methods are more effective for reducing the overall temperature of the mold. In the actual production process of die-casting molds, the temperatur...
