Aluminium alloy cooling forming die and process thereof

The invention discloses an aluminium alloy cooling forming die and a process thereof. The aluminium alloy cooling forming die comprises a bottom plate; a long plate is fixedly connected to the right side of the top of the bottom plate; and a circulating assembly is arranged on the right side of a plate heat exchanger. Through the rotary connection relation between a round block and a round shell and the clearance fit between a sliding rod and the round block, when a round plate rotates, the sliding rod slides left and right on the inner wall of the round block; meanwhile, the round block swings by a certain angle; therefore, water circulation is further conducted on a template and the plate heat exchanger through the cooperation and connection between the round shell and two hoses; the water circulation rate is increased; the cooling forming rate is increased; therefore, the cooling forming rate of aluminium alloy is more rapid; through the rotary connection relation between a first short handle and second sh
