ABSTRACT:
An injection molding machine includes a stationary platen, a movable platen constructed for movement relative to the stationary platen, at least one tie bar for tension-proof connection of the fixed and movable platens, and a traction transmitting securing device including a securing element, disposed on a rear side of one of the platens, for interacting with the tie bar within an engagement zone. The securing element and the tie bar are provided with a number of projections and recesses in axial spaced-apart relationship to establish a form-fitting connection, whereby the projections and the recesses are pressed together when exposed to a tensile stress and interlock at an axial clearance which increases along the engagement zone in axial direction corresponding to the tensile stress of the tie bar.
