mold quick release

18/12/2019 at 14:14

after seeing someone elses idea for a mold quick release and the v4 idea, I though I would share mine.

 

running the extrusion at 60rpm, HDPE and 250c temp setting, I was filling a mold circle of 65mm x8mm in 30 seconds.

 

With mold changes, and running 4 molds, I was able to average 50 shots per hour.

 

The vice grip pliers are welded to the plate.

 

The mold is 3 parts, water jet cut.  top bottom middle.  Plaved in the mold aligned, clamp.  and extrude. need welding gloves for this.

@btmetz
Leaving one side of the mold fixed to the extruder is a great idea, and the other part of the mold could be attached to a hidraulic piston to automate the opening/closing of the mold 🙂
Have you tested this design already?

hydraulic is too expensive, although i am looking at a hand cranked unit and a timer to run the machine and control the amount injected.

 

This unit below is 106USD.

 

It runs a small 12v pump.  Replace the pump with a SSR (solid state relay) and you got a effective way of metering the amount dispensed.

those units in the youtube videos are a big step backwards from the existing machine development.

I like this idea! I might do this on my injection machine! Thanks!
