Abstract
A closure mechanism for an injection molding machine or extrusion press having a frame, a number of parallel extending rods, a first tool support fixedly connected with the frame and a second tool support displaceable along said rods. There is also provided a hydraulic mechanism or device for displacing the second tool support along the rods. According to the invention the rods possess engaging means and the second tool support possesses engaging elements which can be engaged in the engaging means of the rods. The rods are displaceably connected with the first tool support and the hydraulic device possesses at least one displacement mechanism serving to displace the second tool support with respect to the rods and for each rod possesses an additional displacement mechanism fixedly connected with the first tool support which serves to displace the relevant rod with respect to the first tool support.
