Automotive part hanging punching molding positioning structure

An automotive part hanging punching molding positioning structure comprises a cylinder, a molding lower mold and a position sensor, wherein the cylinder which is fixedly connected with a supporting block drives a positioning mandrel to extend or withdraw, the side wall surface of the molding lower mold faces the moving direction of a positioning mandrel, the position sensor is arranged at the starting end of a puncher pin of a punching machine, and the output signals of the one position sensor are sent to a controller which controls the cylinder. The head of the positioning mandrel penetrates a positioning hole of a product workpiece and is embedded into a positioning mandrel hole of the molding lower mold when the positioning mandrel extends outwards. Compared with the prior art, the automotive part hanging punching molding positioning structure can improve the inconvenience of material arrangement of side positioning and martial taking after molding of the mold and solve the problem of the interference of m
