UPDATE 18/04/17 Build photos added.
This thing is an offset bracket for mounting a 120mm 230v axial fan to an 80mm aluminium tube.
I have recently brought another small tabletop injection moulding machine,and am having issues with the heat travelling up the melting cylinder and prematurely pre-melting the plastic pellets prior to extrusion.
This results in the cylinder not extruding,and plastic pellets getting lodged in the cylinder.
This is an attempt to decrease to heat build up and prevent the heat travelling into the cold area non melt zone of the barrel.
i have decided to use the items i have got lying around the lab.( give them a go first ) ,-)
I shall eventually mill out a water jacket and use a peltier cooling block with external cooling fans.
Hopefully FOR NOW this forced air cooling will make a worthwhile temporary cooling solution,only my experiments / tests would confirm or dismiss.
The two fan setup will be working in a push/pull arrangement to force to cool air around the barrel and removing the excessive heat buildup
All metal 120mm server fans are to be used,this suits the industrial nature of my machine and are more powerful than their 12v counterparts.(also no psu is required)
I am in the process of printing and waiting for parts to arrive.
Tests will be carried out and photos/video of my finding posted shortly.
This design should help with the many small tabletop machine available today that suffer this particular problem of premature melting prior to extrusion.
On my machine the extrusion barrel measures 38mm,i will be drilling out the hole in the aluminium tube to 40mm to account for heat expansion and to allow for slight barrel movement.
