ABSTRACT:
An injection press for forming a mass of plastic material to a desired shape comprising a die carrier plate for supporting a mold having an injection channel formed therein at a location corresponding substantially to the location of the optimum injection point, said die carrier plate having a plurality of bores therethrough arrayed in an X-Y coordinate field; a press plate parallel to said die carrier plate and having a plurality of bores therethrough aligned with the bores in said die carrier plate in said X-Y coordinate field; means interposed between said die carrier plate and said press plate for injecting plastic material into a mold; a closing rod extendable through a pair of aligned bores in said die carrier plate and said press plate, through said interposed injecting means and through the injection channel of a mold on said die carrier plate to force plastic material into the mold; said injection means and said closing rod being selectively positionable in said X-Y coordinate field so that the closing rod will pass through a selected pair of aligned bores in said die carrier plate and said press plate corresponding to the location of the injection channel of a mold on said die carrier plate.
