Abstract
A clamping device for fixing a die on the setting surface of a lateral injection molding machine comprises a clamp main body, plural clamping hydraulic cylinders installed in the output portion at the front end portion of the clamp main body, and a guide mechanism for guiding the clamp main body movably only in the longitudinal direction without separate from the setting surface, in which the clamp main body can be freely changed over in position with respect to the setting surface in the released state, so that it may not be dislocated from the setting surface. The lower base portion of the clamp main body can be divided as a base member to be fixed on the setting surface.
Claims8
For use with a lateral injection molding machine, a press machine, or the like, a clamping device for fixing an object to be clamped on a setting surface of a plate member such as a table, bolster and platen, said clamping device comprising:
- a clamp main body disposed on the setting surface, with its bottom abutting against the setting surface;
- a guide mechanism formed in the clamp main body for guiding the clamp main body on the setting surface so as to be movable forward and backward in a longitudinal direction without separating from the setting surface;
- an output portion formed in a front end portion of the clamp body, and confronting the setting surface across a gap for admitting an end portion of the object to be clamped;
- and
- plural hydraulic cylinders arranged in the output portion in one row in the direction orthogonal to the longitudinal direction, directed in a direction orthogonal to the setting surface, and capable of extending and driving piston rods toward the setting surface to press directly against said end portion.
