The locating rings are circular members fitted on the frontal face of a mould over the sprue brush. Its job is to align the orifice of the cold or hot sprue with the through-hole present in the stationary platen. The mould is registered in the correct position on the injection machine. It helps to remove leakage by aligning the sprue bush and the nozzle.
Types of locating rings
Some common types of locating rings include:
Standard/basic: These locating rings can properly align a mould to the platen.
Extended lead-in/tapered: These help to place the mould in the machine easily. It reduces damage to the platen and the ring.
Clamp: These can retain the sprue bushing and prevent it from ‘blowing back.’ It reduces the need for an extra machining step.
Flanged or ‘platen-backed’: They can provide more support to the mould's centre and can add shim to the bottom of the flange.
Importance of locating rings
The critical use of locating rings is evident because it ensures that the correct position between the injection machine and the mould is sustained. It can help by securing the bearing in the proper place in the housing on both sides of the shaft axial.
