Injection molding machine of the toggle-type mold clamping mechanism

摘要

A toggle clamping mechanism for an injection molding machine includes a toggle link, a crosshead connected to the toggle link, and a driving device for driving the crosshead. A ball spline shaft is provided parallel to a ball screw for driving the crosshead. Further, a ball spline nut provided in the crosshead is engaged with the ball spline shaft so that the crosshead may be guided by the ball spline shaft.
