Hello
Inspired by people using a car jack I came up with this idea: Instead of bolting the mould-halves together and screwing it onto the injection nozzle simply use a parallelogram-based construction. Fix the left side onto a wall. To inject simply lift up the whole injector, insert the nozzle in the cavity of the mould then inject. The pressure on the lever should keep all in place.
Tell me what do you think about it?
