Summary:The utility model discloses an oil way structure of a driving valve of an extruding machine. The oil way structure comprises a hose and a backflow check valve, a backflow pipeline is arranged on one side of the middle cavity, and the extending end of the backflow pipeline is communicated with one end of the hose; the other end of the hose is communicated with the backflow check valve; the backflow check valve is communicated with a port A1 of the EESV7040-09 electro-hydraulic reversing valve group through a pipeline; a port A1 of the EESV7040-09 electro-hydraulic reversing valve group is communicated with an oil path 9.1 of a reversing valve in the EESV7040-09 electro-hydraulic reversing valve group; a reversing valve 9.1 in the EESV7040-09 electro-hydraulic reversing valve group is communicated with a connector of a three-way pipe; and the other interface of the three-way pipe is communicated with the oil tank. By the adoption of the oil way structure, the defect that the driving valve hydraulic oil cylinder
