Abstract
A drive unit ( ) is actuated to rotate a ball screw ( ). Then, a ball nut ( ) included in the ball screw and a cross bead ( ) advance toward a movable platen ( ) to extend a toggle link mechanism ( ) gradually. Consequently, the movable platen ( ) advances along tie bars ( ), a movable platen support member ( ) attached to the movable platen ( ) moves on a base frame ( ) and a movable mold ( ) is brought into contact with a stationary mold ( ). When the mold consisting of the movable mold ( ) and the stationary mold ( ) is thus clamped, a part of the frame provided with a recess ( ) of the movable platen support member ( ) is deformed elastically to permit the deformation of the movable platen ( ) and movable mold ( ). Thus the movable platen ( ) is not restrained from deformation, clamping force can be uniformly applied to the mold and accurate moldings can be molded.
