In-mold riveting device of stamping mold

Abstract

The invention discloses an in-mold riveting device of a stamping mold. An in-mold riveting unit of the in-mold riveting device comprises a push rod, a punch and a rivet feeding mechanism, wherein the push rod and the punch are arranged on an upper mold body in a front-and-back mode, and the rivet feeding mechanism is arranged on a lower mold body; the rivet feeding mechanism comprises a rivet positioning base and a rivet positioning plate; the rivet positioning base is arranged on a buoyancy lift body capable of sliding up and down and is opposite to the punch; the rivet positioning plate is arranged on the front side of the rivet positioning base and is arranged at the rear end of an upper sliding plate capable of sliding front and back; the bottom of the rivet positioning base is connected with the rear end of a lower sliding plate capable of sliding front and back through a matched slope step; a return spring I for resetting the buoyancy lift body downwards, a return spring II for resetting the upper sliding plate backwards and a return spring III for resetting the lower sliding plate forwards are arranged; a lower push wedge head obliquely arranged towards the upper rear portion is arranged at the lower end of the push rod; an upper push wedge face obliquely arranged towards the upper front portion is arranged on the push rod; an upper push wedge groove aligned and matched with the upper push wedge face is formed in the upper sliding plate at the reset position; and a lower push wedge groove aligned and matched with the lower push wedge head is formed in the lower sliding plate.
