METHOD AND DEVICE FOR INSTALLING AND REMOVING A PLASTICIZINGSCREW

摘要

The invention relates to a method and a device for the assembly and disas sembly of the preplasticizing spindle (1) of a ram or drive end (11) of a wo rm drive system of an injection molding machine by means of a clamp coupling (10). The worm drive system is designed for a controlled linear and rotary movement of the preplasticizing spindle (1). The coupling occurs by means of clamping agents which are preferably in the form of mechanical clamp coupli ng (10), wherein the rotary driving power and the worm return force are tran sferred via frictional engagement, and the axial injection force is transfer red via an end stop. The assembly and disassembly procedure is supported by being controlled by the worm drive system. The preplasticizing spindle (1) c an also be developed and coupled or decoupled as a heat-shrinkage connection or as a hydraulic tension system (23), wherein the preplasticizing spindle (1) is introduced during coupling to the end stop.
