What are Mold Locating Rings?

A locating ring‘s basic job function is to locate or align the orifice of the hot or cold sprue with the through-hole in the machine’s stationary platen.

The sprue orifice is usually in the center of a sprue bushing, and the locating ring aligns the bushing to the center of the platen. Locating Rings – Fixing Rings / Locating rings for pedestal bearing housings.

The locating ring is usually in the center of the mold. Sometimes, though, the locating ring is offset by several inches to reduce the size of the mold base, such as with a single-cavity, edge-gated part.

Locating rings are used in split Plummer block housings to locate the shaft axially in both directions.

Positioning locating ring design requirements

The positioning of the locating ring is a structural part that plays a role in positioning when the mold is installed on the injection molding machine. The diameter of the domestically-made positioning ring is 0.2~0.4mm smaller than the panel hole of the injection molding machine.

Generally, large molds need to press the sprue sleeve with a positioning ring to prevent the fixing screw from being broken by the reaction force during injection molding.
