A spraying tool structure of a rubber product comprises an upper plate and a lower plate, wherein the upper plate and the lower plate are vertically positioned and arranged through a positioning pin,and a spraying groove is formed in the upper plate through processing to form a spraying area. A limiting groove for the rubber product to be placed and corresponding to the spraying groove is formedin the lower plate through processing, four positioning pins located on the periphery are arranged between the upper plate and the lower plate, bevel edges are adopted on two sides of the spraying groove, and a spraying position area is formed on a bottom surface groove of the upper plate. The clearance of the compression part at the spraying and non-spraying boundary position of the upper plate is 0.05 mm. The spraying tool structure has the advantages that input is fewer, production operation is convenient, the spraying area is clear in boundary and accurate in position, the production efficiency is high, the labor intensity can be reduced, the surface treatment quality of the rubber product is stable, the consistency is good, and large-batch production can be achieved and the like.
