Abstract
An apparatus for injecting a molten material including an injector, a rail, a bell crank, and a frame supporting the injector via the rail for guiding the linear translation of the injector along the frame. The apparatus includes a first guide and a second guide slideably coupled to the rail, the second guide attached to the injector and spaced from the first guide along the rail, and a bell crank coupled to the first guide and second guide to provide a load-balancing mechanism.
Claims19
An apparatus for injecting a molten material comprising:
- an injector for injecting the molten material;
- a rail;
- a first guide and a second guide slideably coupled to the rail, the second guide attached to the injector and spaced from the first guide along the rail;
- and
- a bell crank including a first location, a second location, and a third location arranged in a triangle, the bell crank rotateably coupled to the first guide at the first location, the bell crank rotateably coupled to the second guide at the second location such that applying a linear force at the third location in a first direction from the second guide towards the first guide translates the first and second guides in the first direction along the rail.
