Jig for automatically punching water gap of injection molded part

The invention discloses an automatic water gap punching jig for an injection molding part, and aims to solve the technical problems that the working intensity of workers is increased by an existing manual water gap removing mode, meanwhile, the quality defects that a product subjected to water gap removing has burrs and is not smooth exist, and the quality of the product subjected to water gap removing is difficult to guarantee. The jig comprises a positioning die base, a driving air cylinder and a cutter, a positioning male die is fixedly connected to the upper surface of the positioning die base, and an avoiding groove is formed in one side of the positioning male die. A product is placed on the positioning male die on the positioning die base, at the moment, a water gap of the product is located on the side, close to the avoiding groove, of the through groove, then the driving air cylinder is started to drive the movable rod and the cutter to move, the cutter moves towards the avoiding groove in the moving
