Stepped Tension Links Oval Hole Length (CB)

These stepped tension links are used in injection mold opening and load-transfer tooling where repeatable stiffness and controlled compliance are required. The fixed-side CB mounting aligns with fixed-side socket head cap screws, helping maintain consistent installation and predictable behavior cycle after cycle.

Automotive connector and housing molds often require stable gate/runner-related movement under varying clamp-cycle loads. The adjustable oval hole length (in 5 mm increments) lets designers tune the effective link compliance to manage misalignment tolerance and optimize opening timing.

Large-part medical device housings benefit when load must be transferred smoothly without excessive deflection that could affect sealing or surface finish. This variant supports controlled deflection up to 32%, making it suitable for managing engineering loads where a balance between compliance and stiffness is critical.

• Use fixed-side CB mounting to ensure alignment with socket head cap screws.
• Select oval hole length to match required stroke/control range.
• Apply where controlled compliance (up to 32%) improves stability under load.

The provided product data does not specify a steel grade or heat treatment state (e.g., quenched & tempered, nitriding). As a result, the exact hardness in HRC, wear resistance rating, and toughness trade-offs cannot be stated from the available specifications.

For engineering selection, treat this as a geometry- and mounting-defined tension link component: the stepped form and oval hole-length adjustability govern stiffness and deflection response (allowable controlled deflection up to 32%).

• When integrating into a mold, confirm the supplier’s actual steel grade and heat treatment before finalizing load calculations.
• If multiple material options exist in your configuration, compare hardness for wear-critical duty and toughness for impact/shock loads.
• Validate that the chosen material meets your expected cycle life and any corrosion requirements in the molding environment.

Select the tension link dimensions by matching the mechanical interface and the required stroke/control range in the mold opening controller assembly. Start with the fixed mounting method: this component is specified for the fixed side for socket head cap screw (CB), so it must pair with the corresponding screw interface on the fixed plate.

Next, choose the thickness and planform geometry to meet stiffness needs: Thickness is available as 9 mm or 16 mm, and width A is available as 19, 25, 32, or 38 mm.

Then set the motion/tuning parameters. The oval hole length is described as adjustable in 5 mm increments; use the required effective stroke or compliance target to determine the oval hole length. Select the slotted hole pitch S = 50 ~ 100 mm and the dimension alteration range SC from the provided options: 51–269 (with one configuration), 81–299, or 101–349.

• Confirm that the selected geometry keeps deflection within the specified 32% limit under maximum load.
• Verify fit with the CB socket head cap screw and the installed guide pitch; tolerance values are not provided, so use your drawing standards during design.
