    Convert injection mold clamp to shop press advise

    I have a clamping unit from a Nissei 120 ton injection molding machine. I want to stand it up on end, and use it as a press for forming aluminum parts.
    I know it will be slow because I will be feeding it with a smaller hydraulic pump that it originally had, but it should have lots of force.
    I have built presses with standard cylinders with 2 ports per cylinder, but this one is a bit confusing.
    It has a high speed cylinder and a high power cylinder, in one unit. It seems to have 3 pressure lines, ports 1,2 &4 in the pic. Port 3 seems to be a low pressure drain back to the tank?
    Any advice on connecting this to a hydraulic power pack would be appreciated.

    It's been about 40 years since I worked on injection mold machines, but it looks like Port 1 is the high pressure, Port 2 is the high speed retract, Port 3 looks like a case drain, and Port 4 is the high speed extend.

    V39 looks like a case drain. You may need some hydraulic magic to pre-fill the main cylinder while the high speed cylinder is extending, else it will try to pull a vacuum in there.
