In the die casting production process, the cooling system for temperature control refers to a specialized subsystem used to regulate the temperature of molds, die cast workpieces, and related equipment. Through the circulation of media (such as water, oil, or special coolants), it absorbs, transfers, and dissipates heat, ensuring that the die casting process always remains within the preset temperature range. It is a core component of the die casting temperature control system, directly related to mold thermal balance stability, workpiece forming quality, and production efficiency. It is the key equipment for solving the fundamental challenge in die casting: after high-temperature molten metal is injected into the mold, rapid cooling is required for shaping, while avoiding mold cracking caused by excessive temperature differences.

From the perspective of working logic, the system achieves temperature control through the closed-loop process of “heat collection – medium transfer – heat release – medium return.” First, the cooling medium (such as industrial pure water or heat transfer oil) flows through the preset cooling channels inside the mold, absorbing the large amount of heat generated after molten metal is injected into the mold and workpiece. Then, the heat-carrying medium is delivered through pipelines to the cooling unit (such as radiators, cooling towers, or chillers), where the heat is dissipated into the external environment by air or water cooling methods. Finally, the cooled medium flows back into the mold’s circulation channels, completing one cycle of temperature control and continuously maintaining the mold temperature within the appropriate process range (for example, commonly 50–180℃ for aluminum die casting, subject to adjustment according to material and structure).
