ABSTRACT:
A tie rod structure for a die closing unit of an injection molding machine in which several parallel tie rods hold together a stationary die carrier plate and a stationary head plate, for example, and where the tie rods are seated in attachment bores of the connected plates whose diameter is the same as that of the tie rod guide portion, a threaded tie rod portion on the outside of the plate carrying a threaded abutment collar which is clamped against the plate by a clamping member engaging the extremity of the tie rod. The clamping member may be rotatable out of the way of the tie rod, in order to permit retraction of the latter.
