<p>PURPOSE:To surely hold the pressurizing state by locking a primary slide to the fixed side to enable mechanical reaction support. CONSTITUTION:A working machine is so constituted that a secondary slide 6 for pressurization is built in a primary slide 5 driven by oil hydraulics in such a manner as to be driven by the oil hydraulics and a mold 7 or the like is fitted to the secondary slide 6. In this working machine, the primary slide 5 is provided with a hydraulic cylinder 20 with a small diameter and capable of elevating rapidly, and the secondary slide 6 is provided with a hydraulic cylinder 25 with a large diameter, and can be pressurized with a small stroke. The primary slide 5 is mechanically locked on the fixed side of a platen 3 or the like by a hydraulically operated diameter enlarging and reducing clamper 11.</p> |
