Various embodiments provide methods and apparatus for cooling a mold in a compression molding assembly, thereby enabling increased cycling speed and efficiency. Embodiments include a coolant flow path that transports a fluid coolant into and out of a cooling ring around the molding assembly's core. The coolant flow path may divide into several channels within the cooling ring. The coolant flow path may also include a series of stages with varying volumes or cross sectional areas designed to regulate the flow of coolant.
