Question by Robert Obrien: I need help Designing a Hydraulic Scenario for school?
Having trouble with this piece in class…
Scenario
I work for a company that builds plastic injection molding machines. my job is to design a hydraulic circuit that will perform the folowing operations:
Open and close a mold with a hydraulic cylinder. (i understand this one)
Powedr a hydraulic motor to trun a large screw that feeds hot plastic into the mold. (i also understand this.)

(what i dont understand)
The motor and the cylinder should be capable of operating separetely, BUT THE MOTOR SHOULD ONLY BE ABLE TO TURN WHEN THE MOLD IS CLAMPED.

how can i do that?

Answer by Wingman
Without seeing the injection molding machine, all I can suggest is to add some kind of limit/ micro switch to the mold hydraulic cylinder or the moving part of the mold door.

This limit/ micro switch can then be wired in series with the Start push button for the hydraulic motor.

Wire it up as a normally closed circuit when the door is clamped.
