ABSTRACT:
A plasticizing unit for an injection molding machine includes a carrier block; a plasticizing cylinder securable to the carrier block; an injection nozzle having a nozzle body connected to the front end of the plasticizing cylinder; a discharge outlet at the front end of the nozzle body; a valve needle cooperating withe the discharge outlet and having a closed position shutting off the discharge outlet and an open position allowing discharge of material from the plasticizing cylinder through the discharge outlet; force-transmitting linkage means being connected to the valve needle; and a power unit for displacing said force-transmitting linkage means and the valve needle into the open or power unit for displacing the valve needle into the open or closed position. The nozzle body has a throughgoing, linear, unobstructed nozzle channel extending within the nozzle body from the rear end of the nozzle body to the discharge outlet and being in an axial alignment with the plasticizing cylinder; and a guide channel extending within the nozzle body to the discharge outlet at an acute angle to the nozzle channel. The valve needle is slidably received in the guide channel. At least one of the force-transmitting linkage means is guided respectively connected to the power means by coupling means.
