ABSTRACT:
An injection molding machine (1) comprising a fixed mold half (4) mounted on a fixed plate (3) integral with the machine frame (2) and a moveable mold half (9) mounted on a moveable plate (8) supported in translation on the machine frame (2) and guided along guide columns (5) integral with the fixed plate (3), to pass from a mold closing position to a mold opening position, and a closing and clamping system (10) comprising clamping means, integral with the moveable plate (8) and acting on a portion of the guide columns (5) to lock the moveable plate (8) in the closing position. The clamping means comprise a plurality of locking inserts (22) mounted slidably within seats (21) of a body (13) integral with the moveable plate (8) to pass from a non clamping position to a clamping position in which they act, in a locking relationship, on the guide columns (5), each locking insert (22) having a circular hole (25) to receive an eccentric shaft (26) in an eccentric position, so that rotation of the eccentric shaft (26) causes translation of the insert (22), drive means being provided such as to set the eccentric shafts (26) in rotation synchronously to allow opening/closing of the clamping means.
