Description

Lead frame forming die Technical Field The utility model relates to the technical field of lead frames, in particular to a lead frame forming die. Background The lead frame is used as a chip carrier of an integrated circuit, is a key structural member for forming an electric loop by electrically connecting an internal circuit leading-out end of the chip with an external lead through bonding materials such as gold wires, aluminum wires or copper wires, plays a role of a bridge connected with an external lead, and is an important basic material in the electronic information industry because the lead frame is needed to be used in most of semiconductor integrated blocks. The utility model patent publication No. CN 214108477U discloses a lead frame forming die, which drives a punching pipe and an auxiliary plate on a movable plate to move downwards through the driving of an air cylinder, so that one side of the auxiliary plate, which is close to the center of the movable plate, is contacted with one side of a clamping plate, which is far away from the center of a supporting seat, and the clamping plate is extruded towards the center of the supporting seat due to the shape characteristic of the auxiliary plate, so that the lead frame in an inner cavity of the supporting seat is fixed, and the lead frame is automatically fixed.
