Abstract

PURPOSE:To cut a gate without damaging a lead frame in high working efficiency by applying bending force to the end of the gate by pressing the upper surface of a roller package. CONSTITUTION:A lead frame 1, to which a runner 4 and a gate 5 are adhered, is supported in such a manner that the gate 5 is disposed on the upper flat surface of a projection 2 and the rubber 4 is disposed on the bottom of the recess groove 19, and is placed on a lower die 18 substantially horizontally. A runner retainer 17 which is projected from the lower surface of a substrate 7 is pressed on the upper surface of the runner 4 to hold the runner 4 therebetween. Then, a roller bar 15 drops, and a roller 16 pressed the upper surface of a package 2. At this time the lead frame 1 is inclined with the end of the gate 5 as a fulcrum, and bending force is applied to the end. In this manner, the runner 4 and the gate 5 are cut at the coupling part of the package 2. The lead frame 1 which is isolated from the gate 5 is dropped into the groove 22 and arranged.

Board 7 due to a mechanism not shown
is lowered, and after the runner presser 17 protruding from the lower surface of the substrate 7 presses the desired upper surface of the runner 4 and clamps the runner 4, the lowering of the substrate 7 is stopped. Next, the hydraulic cylinder 8 is activated, the roller bar 15 is lowered, and the roller 6 is moved back.
- Press the top surface of the cage 2. Since the lower die 18 below the package 2 has escaped, the package 2, that is, the lead frame 1, is tilted with the terminal portion 5' of the gate 5 as a fulcrum, and a bending force is applied to the terminal portion 5'. Since the cross-sectional area of the portion is extremely small, the gate 5 is cut at the terminal portion 5', which is the joint portion with the package 2. The lead frame 1 separated from the gate 5 falls into the groove 22 11.
