Locating Rings Through Hole Bolt Stopper

This through-hole bolt stopper locating ring is used to lock die set position in injection mold tooling where repeatability of alignment is critical. It suits production die assemblies with standard locating ring interfaces and through-hole fastening so the upper and lower halves return to the same register after clamping.

• Automotive connector and housing molds: Use 4-bolt (four holes) mounting to maintain consistent cavity alignment under higher repeat cycle loads, especially when gate/runner components require tight register control.
• Appliance and electronics housings: The 2-bolt (two holes) configuration provides stable alignment while simplifying base layout, making it well matched to common die set footprints.
• Thin-wall consumer parts: The selected height options (T = 10–30 mm) help match die stack-up and stopper engagement depth, supporting repeatable setup during production maintenance.

With multiple outer diameters (D = 60–150 mm), this variant can be chosen to fit the locator requirements of your ring-style die base.

The provided specifications for this locating ring define dimensional variants (D = 60, 100, 110, 120, 150 mm; T = 10–30 mm; 2-bolt or 4-bolt). No steel grade, hardness, or heat-treatment state is included in the input data, so material properties such as HRC, wear resistance, and toughness cannot be stated reliably.

In typical locating ring applications, engineers select a steel based on required wear resistance at the bolt-stopper interface and enough toughness to resist chipping during repeated clamping cycles. If you are using comparable locating-ring standards from your existing die base, match the locating ring material to the die set base material to reduce differential wear and ensure stable register.

• If an alternate steel option is offered in your procurement catalog, compare hardness (higher for wear resistance) versus toughness (better impact resistance).
• When heat treatment options (e.g., quench & temper, nitriding) exist, prioritize the state that best matches your expected contact pressure and maintenance interval.

Correct selection is primarily driven by outer diameter (D), height (T), and whether your mold base uses 2-bolt or 4-bolt through-hole mounting.

• Outer diameter (D): Choose one of D = 60, 100, 110, 120, or 150 mm to match the locator bore/seat size in your die base design.
• Bolt pattern compatibility: Select the unit built for 2 holes or 4 holes to align with your through-hole fastening layout and ensure the stopper engages correctly during clamping.
• Height (T): Select T = 10, 15, 20, 25, or 30 mm based on required engagement depth within the die stack-up. This influences when the die halves reach the final register.

For fit and tolerance, base the clearance/interference on your existing locating-ring interface specifications. If your die design uses standard locating ring fits, keep the same tolerance class for D so the register is repeatable across production cycles.
