Abstract

This utility model relates to the field of radiator mold technology and discloses a radiator mold, including a lower mold, an upper mold, and a forming groove formed on the lower mold. A support is installed on the bottom surface of the lower mold. This utility model provides a cooling groove for heat dissipation inside the forming groove by forming a cooling groove inside the lower mold, and a relief box connected to the cooling groove. By controlling the descent of the sealing plate inside the relief box, the amount of liquid entering above the sealing plate is controlled. When material is input into the forming groove, the sealing plate descends, preventing the liquid from contacting the adjacent surfaces of the cooling groove and the forming groove. When heat dissipation is required for the formed radiator shell, the sealing plate rises, allowing the cooled water to fill the cooling groove and carry away the heat from the radiator shell. This avoids the problem of cooling during the material flow process, which affects the forming quality. At the same time, after forming, it can continue to be cooled by cold water, accelerating the production efficiency of the radiator shell and improving its practicality.
