Retainer Angular Pins Single/Double Mounting Bolt Holes

These retainer angular pins are used in large-scale injection mold tooling and die-casting assembly fixtures where precise component positioning must be maintained across repeated clamping cycles. They are commonly incorporated into machinery mold base subassemblies, using the single or double mounting bolt hole configuration to stabilize alignment between plates, slides, or die components.

In automotive and industrial connector mold builds, the angular engagement helps resist part-to-part shifting during high-cycle tightening, supporting consistent shut-off alignment. The 10–20° angle range and available thickness (20–55 mm) make this variant suitable for controlling lateral retention without over-constraining the system.

For automation equipment and production fixtures, selecting the correct pin diameter (D = 8–30 mm) allows reliable clamping stability around multiple bolt patterns (1 or 2). The steel options (S45C or HPM2T-comparable) further support long service life under moderate wear conditions.

This series is available in S45C or HPM2T-comparable steel. S45C is a carbon steel commonly used for components requiring good toughness and machinability, typically balancing wear resistance with impact tolerance in industrial assemblies.

HPM2T-comparable steel (high-performance tool steel class) is selected when higher wear resistance and improved dimensional stability under repetitive contact are needed. Compared to S45C, the trade-off is that higher hardness requirements can reduce toughness if not properly heat-treated and matched to load conditions.

• HRC / hardness: Not specified in the provided data, so final hardness should be verified against the supplier’s heat-treatment standard for the selected grade.
• Heat treatment state: Not specified; commonly for tool-steel options this includes quench & temper, and for certain applications may be paired with surface hardening (e.g., nitriding) depending on design targets.

Choose S45C for robust toughness, and HPM2T-comparable for enhanced wear resistance where repeated clamping friction and angular contact are critical.

To select the correct angular pin retainer, match the angular pin diameter (D) and the thickness to the mating mold fixture or retainer interface. This series supports D = 8–30 mm, so start by measuring or specifying the pin pocket/bore size required by the core/cavity alignment feature.

The geometry also depends on A (Angle) = 10–20°. Ensure the chosen angle aligns with your intended retention action (lateral resistance during clamping). For stack height and bolt clearance, use T (Thickness) = 20–55 mm and TC (Thickness alteration) = 10–27.5 mm to fit the assembly without shifting the alignment datum.

• Bolts: Select 1 or 2 retainer clamping bolt version based on your bolt hole pattern.
• Tolerance & fit: The provided data does not list tolerances; design should account for machining/bore tolerance and ensure the mating interface provides reliable contact without excessive clearance.
• Fixed vs configurable: A is fixed at 10–20° for the series, while D, T, TC, and bolt count are variable.
