Claims (1)

[Scope of utility model registration request] A supply port for an IC lead frame that is cut by an upper die and a lower die attached to a lower die mount fixed to the machine body and an upper die mount provided on the machine body to move up and down relative to the lower die mount. It is mounted on the machine body with the side or the waste material discharge port side facing one side of the machine body, and the upper mold mounting base has an insertion port on the bottom side of the machine body, and the insertion port is arranged in the direction in which the IC lead frame is transferred. A fitting groove that is open to the groove is installed along the transfer direction, and molds such as a punch for cutting resin, a punch for cutting tie bars, a punch for cutting leads, etc. are fitted into the fitting groove so that they can be freely inserted and removed. The upper mold is assembled to the upper mold mount by integrally connecting and assembling it to the base, and the base is fitted into the fitting groove and fixed to the upper mold mount. To do IC
