Shunting mechanism, rapid heating control method and mold heating system

The invention discloses a shunting mechanism, a rapid heating control method and a mold heating system. The shunting mechanism comprises at least one fluid inlet, a plurality of fluid outlets, and a plurality of first flow control valves, wherein the first flow control valves control fluid outlet flow corresponding to the fluid outlets. The mold heating system comprises a high-temperature fluid source, the shunting mechanism, a mold and a controller, wherein the controller is used for carrying out process matching on the number, the flow and the on-off time of shunting pipelines in the shunting mechanism according to the mold size, the mold structure and the raw material thermal property parameters. The flow resistance of the shunting mechanism is small, and each fluid outlet can be independently controlled. The mold is divided into different zones for heating, in order to meet requirements of the mold structure, the mold size and the raw material characteristics, different zone targettemperatures are arrange
