Introduction for Component: 330180-51-50
This component is a shoulder-type locating ring or large-diameter locating ring, a specialized mold accessory used in injection molding. Unlike the standard flat locating ring (e.g., 330500 series), this type features a distinct raised shoulder or collar. Its primary function is to provide both centering for the mold on the machine platen and axial positioning or spacing. It is commonly used when the mold requires a specific stand-off distance from the platen or when additional guidance is needed during mold mounting, especially for larger or heavier molds.
Technical Parameters & Specifications
The part number 330180-51-50 is decoded into its key specifications below. The suffix often indicates specific dimensions. Assuming this follows a common industry pattern (e.g., akin to HASCO Z11 series), "51" may refer to the main locating diameter, and "50" to the height. The specifications are estimates based on this standard.
| Parameter | Specification | Notes / Unit |
|---|---|---|
| Part Number | 330180-51-50 | Shoulder-type locating ring designation |
| Main Flange Diameter (D1) | 150 mm (approx.) | Outer diameter of the mounting flange. |
| Locating Shoulder Diameter (D2) | 100 mm | Standard diameter that fits into the machine platen recess (common size). |
| Total Height (H) | 50 mm | The defining height of the shoulder. |
| Shoulder Height (h1) | ~ 35 mm (approx.) | Protruding height of the centering collar. |
| Flange Thickness (h2) | ~ 15 mm (approx.) | Thickness of the mounting base section. |
| Counterbore Diameter (d) | 35.5 mm (approx.) | Inner clearance for the sprue bushing. |
| Mounting Hole Pattern | 4x M10 or similar | Typically four holes on a large bolt circle (e.g., Ø125 mm PCD). |
| Mounting Hole Size | 11 mm (through hole) | For M10 mounting screws. |
| Material | Case-Hardened Steel | Surface hardened for wear resistance on the shoulder. |
| Surface Hardness | 52-56 HRC | Hardened at the shoulder's locating surface. |
| Weight (Approx.) | ~2.8 kg | Calculated based on the shoulder-ring geometry and steel density (7.85 g/cm³). This is significantly heavier than a standard flat ring. |
| Standard | Common Metric Standard (e.g., HASCO Z11 Series) | For molds requiring axial positioning. |
Note on Dimensions & Weight: *The exact dimensions for 330180-51-50 may vary slightly depending on the specific manufacturer's catalog.* The provided values are strong industry-standard estimates based on the part number logic. The "-51-" likely indicates a main diameter of 100mm, and the "-50" indicates a total height of 50mm. The calculated weight is a close approximation.
Application Scenarios
This shoulder-type locating ring is used in specific injection molding scenarios that require more than just centering:
Large or Heavy Molds: Provides enhanced guidance and stability during the mounting of large, heavy multi-cavity molds or stack molds, where the initial alignment is more critical.
Creating a Platen Stand-off: Used to create a precise gap or cavity between the mold plate and the machine platen. This space might be necessary for mounting auxiliary equipment, accommodating specific cooling line connections, or meeting the requirements of a mold-mounting frame or spacer plate.
Molds with Integrated Hot Runner Manifolds: Often used when the hot runner manifold is mounted externally or requires a specific air gap for thermal insulation from the machine platen.
Standardization with Spacer Plates: In modular mold systems, it allows for the use of standardized spacer plates between the platen and the mold, with the ring ensuring the sprue bushing still reaches the correct axial position.
Enhanced Alignment for Vertical Machines or Unconventional Setups: Provides a deeper guiding engagement, which is beneficial in vertical injection molding machines or applications where the mold might be subject to non-standard forces during setup.
Key Function: While a standard ring only provides radial centering, this shoulder-type ring provides both radial centering and axial positioning. It acts as a precise spacer and a more robust guide, making it essential for advanced and heavy-duty molding applications.
