Loose Core Related Parts for Direct Ejector Pin

Adjusting Rod Set Specifications

The document provides detailed specifications for adjusting rod sets used with direct ejector pins. Key parameters include pin diameter (φD), thread size (M×P), and various dimensional measurements such as Hf, h, φd, B, Ba, S, Sa, Ha, and Hb. The adjusting rods come with lock nuts and are available in multiple sizes ranging from M14×1.5 to M36×1.5, with corresponding pin diameters from 42 mm to 60.5 mm.

Material and Surface Treatment

Both the adjusting rods and ejector pins are made from S45C steel, thermally refined to a hardness of HRC 23 to 28 (equivalent to C45 or A1045 steel). The surface treatment applied is black oxide, which provides corrosion resistance and durability.

Installation Procedure

The installation involves fixing the ejector pin onto the ejector plate using hexagonal socket head bolts. The tapped hole depth (Ha) and adjusting reference (Hb) allow for an adjustment tolerance of ±3 mm. The document specifies bolt sizes and depths for secure fixing, ensuring proper alignment and function of the ejector pins.

RAHS Series for Inclined Pin Type with Cooling Hole

The RAHS series is designed for inclined ejector pins featuring cooling holes. Specifications include thread sizes M30×1.5 and M36×1.5, with detailed dimensional data such as length (L), diameter (d), and other relevant measurements. These parts share the same material and surface treatment standards as the standard ejector pins.

Summary of Critical Parameters

• Material: S45C steel, thermally refined (HRC 23-28)
• Surface Treatment: Black oxide
• Adjusting Rod Sizes: M14×1.5 to M36×1.5
• Pin Diameters: 42 mm to 60.5 mm
• Adjustment Allowance: ±3 mm on ejector plate
• Fixing Bolts: Hexagonal socket head bolts with specified sizes and depths

Best Practices and Recommendations

Ensure precise measurement of tapped hole depths and adherence to adjustment tolerances during installation to maintain ejector pin performance. Use specified materials and surface treatments to guarantee durability and resistance to wear. For inclined pin types with cooling holes, select the appropriate RAHS series parts to accommodate cooling requirements.
