PURPOSE:To improve machining accuracy by lowering noise due to deflection of a frame and restraining vibration. CONSTITUTION:A frame 1 is divided into an upper frame 4 provided a slide driving mechanism 18 in an upper mold 14 and a lower frame 5 supporting a lower mold 15. The upper frame 4 is supported as possible to elevate lower on the lower frame 5. As the frame is divided into upper and lower frames 4, 5. reaction at pressing time with slide driving mechanism 18 is escaped by ascending the upper frame 4 as possible to elevate lower, to prevent the deflection of upper frame 4. |
