High-Precision 2x4 Connector Insert Mold | Fine-Pitch Pin Ejection System |

Product Specification

This industrial-grade precision injection mold is specifically engineered for the high-volume manufacturing of electronic connectors, specifically wire-to-board or board-to-board types. The mold features a complex "2x4" multi-cavity layout, enabling the simultaneous production of eight identical connector components in a single injection cycle. This configuration is optimized for the demanding electronics industry, where high precision, repeatability, and cost-effectiveness are paramount.

Alternative Names & Working Principle:​

Commonly referred to as a "connector insert mold," "terminal mold," or "electronic pin mold," this equipment operates on advanced plastic injection molding principles. Thermoplastic materials, such as PBT (Polybutylene Terephthalate), LCP (Liquid Crystal Polymer), or PA (Nylon), are heated to a molten state and injected under high pressure into the mold cavities. The defining feature of this mold is its sophisticated internal structure, which includes precision-machined core pins and sleeves to form the delicate connector pins. The mold also features a hot runner system, visible as the blue and metallic components on the right side, which ensures efficient melt delivery and minimizes material waste. Once the plastic cools and solidifies, the mold opens along precision-machined guide pillars, and a specialized ejection system expels the finished connectors.

Material & Craftsmanship:​

The mold body is constructed from high-strength, wear-resistant alloy steel, such as P20 or 718H, ensuring durability and dimensional stability under extreme temperatures and pressures. The cavity surfaces are polished to a high-gloss finish, which is essential for producing connectors with a smooth, burr-free surface, critical for reliable electrical connections. The metallic silver-gray color of the mold frame reflects its industrial-grade quality, while the presence of various sensors and hydraulic components indicates a high level of automation and control.

Performance & Features:

· High Production Efficiency:​ The 2x4 cavity configuration significantly reduces the per-unit cost of production and maximizes the utilization of the injection molding machine.

· Ultra-High Precision:​ The mold is designed to achieve tight tolerances, essential for the precise fitting of connector pins into PCBs or cables.

· Advanced Ejection System:​ The integrated pin ejection system ensures smooth and consistent part removal, minimizing the risk of damage to the delicate connector pins.

· Efficient Thermal Management:​ The mold features a strategically designed cooling system, with precisely drilled cooling channels surrounding each cavity, to optimize heat dissipation and reduce cycle times.

· Reliable Automation:​ The mold is equipped with sensors and actuators for automated operation, ensuring consistent part quality and reducing the need for manual intervention.
