Inclined Direct Push-Up Lifter Pins - Key Flats

Inclined direct push-up lifter pins with key flats are used in mold tooling where loose cores must be guided smoothly during opening/closing. The key-flat alignment helps keep the core orientation stable while the inclined geometry performs controlled lift-and-insertion, reducing misalignment and binding at the transition.

Common scenarios include:

• Automotive and industrial connector housings: use these pins to guide loose core features that require repeatable positioning, improving cycle stability during assembly and ejection.
• Electronics and appliance housings: inclined lifter applications benefit from the smooth push-up action and the key-flat stabilization, which helps protect precision mating surfaces.
• Complex undercut or slide-related inserts: for loose cores such as SCY and SCZN / SCZA, the key flats support consistent insertion/removal under inclined lifter motion.

This variant is suited because the key flats maintain alignment for the specified loose-core part families, enabling reliable assembly operations across the listed size ranges.

The provided specifications for this product focus on geometry and compatibility; no steel grade, hardness (HRC), or heat-treatment state is listed in the input data. For engineering selection, confirm the actual pin material and heat treatment from the manufacturer’s product specification sheet for SKU 110200174050.

In typical lifter-pin applications, the material choice balances wear resistance (for repeated sliding contact and chamfer interaction) against toughness (to prevent chipping under side load during inclined motion). If multiple material options exist for the same geometry in your procurement channel, compare them by:

• Hardness (HRC): higher hardness improves abrasion resistance but may reduce impact toughness.
• Surface treatment: nitriding or similar surface hardening can increase wear life while maintaining a tougher core.
• Heat treatment condition: verify whether the pins are pre-hardened or quenched & tempered to ensure predictable dimensional stability.

Use the confirmed grade/hardness to finalize wear-life and contact-surface strategy.

Select the lifter-pin size by matching the inclined pin diameter (D), the L length, and the chamfer block geometry (F and W) to your mold’s inclined lifter path for the target loose core.

• Diameter D (mm): choose within 8 ~ 30 mm based on the required clearance and the mechanical interface to the loose core.
• Length L (mm): select from 100 ~ 800 mm (or 100 ~ 600 mm, depending on the applicable configuration) to ensure full engagement during push-up and retraction.
• Chamfer dimensions: match F (10 ~ 50 mm) (inclined block side double chamfer length) and W (3 ~ 20 mm) (inclined block side double chamfer width) to the inclined block and contact zone profile.

For fit, design mating features around the selected diameter and chamfer widths so the key-flat alignment engages without excessive clearance. If your mold requires tight positional repeatability, account for normal manufacturing tolerances on the pin and the corresponding core/insert pocket; confirm acceptable clearance limits with your internal spec since specific tolerances are not provided here.

This product is intended for loose-core families SCY and SCZN / SCZA, so verify that the chosen dimensions align with the corresponding core mounting geometry.
