The invention belongs to the technical field of car couplers, and discloses a casting system for car coupler production and manufacturing, the casting system comprises a fixed bottom plate, a sprue, a cross gate, an ingate and a sand mold, one end of the top of the fixed bottom plate is fixedly provided with a first supporting plate, and the other end of the top of the fixed bottom plate is provided with two supporting assemblies in a front-back symmetry mode. Through cooperation of the fixed assembly, the first movable assembly, the first spring and other structures, during casting, the flow limiting assembly embedded in the sprue limits the flow of molten metal, the purpose of reducing the flow speed of the molten metal is achieved, splashing and turbulent flow of the molten metal in a casting system are reduced, and the casting quality of the molten metal is improved. And when the second movable assembly is heated, the length changes according to the thermal expansion and cold contraction ...
