Abstract
An improved design for an injection molding apparatus for creating of products from fluid plastic material wherein a hydraulic flow divider can be used for simultaneously actuating of multiple hydraulic injectors which need not be linearly positioned. This molding apparatus is usable with a hydraulic flow divider since a unique configuration of a fixed frame with a cage mounted movably therein and a hydraulic cylinder assembly mounted movably within the cage allows the injection molding apparatus to use the same amount of hydraulic fluid during each and every stroke regardless of the length of the stroke of the rod relative to the nozzle. This unique capability is achievable by allowing the hydraulic cylinder assembly in its entirety to move within a predefined cage configuration even after the entire stroke is completed in order to allow the cylinder to accept the amount of powering hydraulic fluid associated with a single complete stroke. Further included in this design is a unique position indicating device located externally on the apparatus to indicate the relative positioning internally between the nozzle rod and the nozzle rod tip opening and to indicate the positioning of adjustment thereof.
