Positioning Locking Blocks Angle Configurable, Oil-Free Options

These angle-configurable locking blocks are used during injection mold assembly to provide repeatable positioning and a rigid lock between supporting plates and related undercut/plate components. Their PL fixing style is especially suited to mold builds where alignment must remain consistent from commissioning through high-volume production.

• Automotive connector and bracket molds: Use the oil-free groove/non-oil groove variant to minimize lubricant contamination near critical interfaces, helping maintain stable shut alignment during fast cycle runs.
• Electrical enclosure and housing molds: Select the angle-configurable geometry (G = 5°) to fine-tune how components seat during setup, improving repeatability across maintenance cycles.
• General industrial parts molds with plate subassemblies: The configurable block height (T = 10–45 mm) and wide width range (A/W = 13–78 mm) support fit to common plate thickness and cavity/core layout constraints.

With HPM2T or O1 tool steel, the blocks are designed for dependable wear performance where locating surfaces resist fretting during repeated assembly and lock/unlock operations.

This positioning-locking block is offered in HPM2T or O1 tool steel, both tool-steel options selected for stable wear resistance at mold assembly interfaces. The material choice balances surface durability with toughness needs depending on load and assembly frequency.

• O1 tool steel: Commonly used where good toughness and machinability are required for precision components; it typically performs well for wear resistance when properly heat treated.
• HPM2T: A high-performance tool steel grade intended to improve wear behavior at locking faces, supporting longer service life in repeat-use molds.

While the supplied data lists the grade options, it does not specify hardness or a specific heat-treatment state (e.g., quench & temper, nitriding). For best results, engineers should confirm the delivered hardness (HRC target) and the shop’s heat-treatment process to ensure the desired wear–toughness trade-off for the intended mold duty.

To select the correct locking block, start by matching the block height and inlay geometry to your mold plate/interface layout. The available ranges are T = 10–45 mm (block height) and H/E = 4, 8, or 10 mm (inlay part dimension). Choose the block width from A/W = 13–78 mm to fit the plate supporting area without interference.

• Match length (L): Select from the offered values L = 20, 25, 30, 35, 40, or 50 mm based on the available space along the locating edge in your cavity/core stack.
• Match the angle function: The angle parameter is G = 5°, so compatibility depends on your mating locating surface geometry being designed for that seating angle.
• Fit and tolerance: Use your mold assembly drawing to verify allowable clearance/gap at the locking interface and ensure the selected dimensions avoid clamp-area contact during PL installation.

When possible, confirm whether your design expects a specific inlay depth (H/E) and that the plate thickness supports the selected T without weakening surrounding features.
