Abstract
A closure device for closing a mold tool for manufacturing objects from thermoplastic materials includes a frame including a first yoke, which supports directly one of the two displaceable mold plates supporting the halves of the mold tool, a second yoke remote from the first yoke and spaced tie and pressure rods extending between the first and second yokes. The ends of the tie and pressure rods, proximate to the first yoke, are rigidly connected with the first yoke and the opposite ends of the tie and pressure rods are hingedly connected to the second yoke. The closure device further includes a mechanical drive extending between the second yoke and the other of the two mold plates and a synchronization device for enabling synchronous displacement of the two mold plates.
