Base driving structure for die spotting machine

The invention relates to a base driving structure for a die spotting machine. The structure comprises a base, and two side plates are arranged on the left side of the base side by side. Sliding railsare arranged at the upper ends of the two side plates and the upper end of the base; a lower die plate which slides transversely is installed on the sliding rail. A driving chain wheel is mounted on the left side between the two side plates; one side of the driving chain wheel is connected with a driving motor, a driven chain wheel is installed on the right side between the two side plates, the driven chain wheel is connected with the driving chain wheel through a chain, the chain is connected with the left side of the lower die plate, an ejection oil cylinder is vertically installed in the middle of the upper end of the base, and a plurality of die assembly oil cylinders are evenly arranged around the ejection oil cylinder. The driving chain wheel is driven by the driving motor to rotate,so the chain drags the lo
