AI Technical Summary
Existing circulating cooling devices for powder metallurgy forming dies are only suitable for specific die sizes and cannot be used for dies of different sizes, thus limiting their application.
A cooling device was designed, comprising a base, mounting plate, U-shaped tube, heat dissipation fins, and adjustment mechanism. The device achieves the contact between the heat-conducting plate and the mold surface by driving the slider and telescopic tube with a cylinder. Combined with the pump body driving the condensate circulation and the fan for forced convection, it can adapt to the cooling needs of molds of different sizes.
It achieves universal cooling for molds of different sizes, improves the equipment's versatility and production adaptability, ensures cooling efficiency and uniformity, and avoids localized heating of the condensate.
