Locking Blocks - Fixed Angle & Inlay Height Configurable

These locking blocks are used in injection mold and fixture assemblies where a repeatable, non-slip location for PL bolt fixing is required. The fixed locking angle (set at 0° per the configuration) supports stable anti-shift positioning during clamp and cycle motions.

In automotive connector and small electrical housing molds, the configurable inlay height helps match the block to different plate thicknesses and groove depths, maintaining consistent alignment for slides, plates, or backing components. The oil-free groove option helps reduce contamination risk in environments that are sensitive to oil migration or debris accumulation.

For precision appliance or industrial component tooling, engineers can select the inlay part dimension range to ensure a tight fit against the mating plate features, improving positioning repeatability between maintenance intervals. With multiple length and width options, the blocks can be integrated into different mold base layouts while retaining secure PL fastening.

Available materials include SKD61, HPM2T, and O1 tool steel, each chosen to balance wear resistance and toughness for different tooling duty cycles. SKD61 is commonly used as an H13-class hot-work mold steel in moldmaking due to its hardenability and performance under thermal cycling. HPM2T is typically selected for improved wear resistance and dimensional stability in cutting/forming-related tooling contexts. O1 is an oil-hardening tool steel option when cost and machinability are prioritized for lighter loads.

• Hardness: Hardened steels are typically specified in the ~HRC range appropriate to their role; exact HRC is not provided for this SKU, so confirm with your heat-treatment plan.
• Heat treatment: Expect a quench-and-temper route for SKD61/HPM2T/O1 to reach working hardness, with trade-offs between maximum hardness (better wear) and toughness (better resistance to edge chipping).
• Wear vs toughness: Higher wear resistance grades can trade off impact toughness; choose based on cyclic loads and expected abrasion.

Select the locking block size by matching the block height T (15–45 mm), length L (20, 25, 30, 35, 40, 50 mm), and block width A/W to the available space and the mating plate feature envelope. The product supports multiple width bands (e.g., 13–60, 18–100, 23–130, 38–150, 48–150, 68–200 mm), so verify the required width on the mold base or clamping fixture layout.

Next, configure the inlay part dimension H/E using the available ranges (3–8, 3–10, 3–15, or 4–8 mm) to align the inlay depth with the mating PL installation geometry. The locking angle is fixed at G = 5° per the specification, so ensure the mating pocket/feature has the corresponding angle clearance.

• Fit/tolerance: Confirm working clearances between block and the plate recess; tightening forces for PL bolting can magnify any mismatch.
• Configurable vs fixed: Material and inlay height are configurable via the provided ranges; length and height must be selected from the listed options.
