Abstract
An injection molding machine including a guide coupling for transmitting linear movement to a screw, a screw coupling for transmitting a rotary movement to the screw, a washer-type load cell, disposed between the guide coupling and the screw coupling, for detecting a pressure applied to the screw coupling, and a transmission link having one end thereof coupled to the screw coupling so as to be rotatable relative thereto and axially fixed relative there. The transmission link rotationally fixed relative to the guide coupling.
Claims15
An injection molding machine comprising:
- a guide coupling for transmitting a linear movement to an injection screw;
- a screw coupling for transmitting a rotary movement to said injection screw;
- a load cell, disposed between said guide coupling and said screw coupling, for detecting a pressure applied to said screw coupling;
- and
- a transmission link having a first end thereof coupled to said screw coupling so as to be rotatable relative to said screw coupling and axially fixed relative to said screw coupling,
- said transmission link being rotationally fixed relative to said guide coupling and axially slidable relative to said guide coupling.
