Abstract

Herein disclosed is an automatic mold clamping apparatus for a molding machine. The mold clamping apparatus comprises: support bolts anchored at a peripheral edge of mold clamping positions of the stationary and movable mounts of the molding machine and having axes aligned with the axes of tie bars; clamping members each supported movably relative to the corresponding one of the support bolts between an engaged position, in which the each clamping member is engaged with a portion of a mold, and a disengaged position in which the same is disengaged from the mold; a moving member for moving the each clamping member between the engaged position and the disengaged position; nut members each meshing with the each clamping member for moving the each clamping member to the mold; a wrench member having a socket portion meshing with the each nut member for turning the socket member forward or backward; and a wrench drive member actuated by a cylinder connected to the wrench member for turning the wrench member reciprocally on the socket portion.
