摘要： The novel solution provides a closing part comprising an electromechanical drive for a CD injection molding machine having a working stroke and a servicing stroke. The entire mold closing unit is characterized by the combination of a short-stroke crank mechanism which is operated by an electric motor and which is provided for the working stroke and of a central electromotive column-type nut drive for the servicing stroke. According to the invention, synchronous motors or asynchronous motors are used with corresponding servo boosters to realize servo axles. The central column drive is used as a control element of the closing force control, together with a force sensor for detecting the closing force, as an actual value transmitter and as a control device.

摘要： A device for generating nozzle contact pressure for the nozzle of a plasticizing and injection unit includes a spindle drive system and a measuring sensor to detect when an appropriate nozzle contact pressure has been achieved. The device generates nozzle contact pressure and also makes it possible to adjust and set the contact pressure of the nozzle.
