Mold Carriers/Fixtures

Mold carriers and fixtures are precision-engineered components used in mold conveyor systems within rubber and plastic product manufacturing. Their primary function is to securely hold, position, and transport molds between different processing stations, such as injection molding, casting, or forming operations. These components ensure proper alignment, prevent mold damage during movement, and maintain consistent positioning, which is critical for high-volume production environments.

Mold carriers typically interface with conveyor tracks or robotic systems, enabling automated mold handling. They are designed to accommodate a range of mold sizes and weights, with load capacities typically from 500 to 5000 kg and mold size ranges from 200 to 1200 mm. Positioning accuracy is maintained within ±0.05 mm, and repeatability for automated mold change systems is ±0.02 mm. Operating temperatures range from -20°C to 80°C, and the electrical supply for sensors and actuators is 24 V DC ±10%. Ingress protection ratings are IP54 to IP65, ensuring dust and water resistance.

Materials commonly used include carbon steel, stainless steel, and aluminum alloy. For structural parts, carbon steel grades such as S45C to S55C (per JIS G4051) are specified, with induction hardening to achieve surface hardness of HRC 40–50. Clamping forces range from 10 to 50 kN to hold molds securely during transport. The weight of the carriers themselves ranges from 50 to 300 kg, affecting conveyor load and handling.

Operating pressure, when applicable, is 1.0–1.6 MPa. These parameters serve as reference ranges; actual values must be confirmed with the manufacturer for specific models and applications. Mold carriers and fixtures are essential for automated mold handling, reducing manual intervention and improving production efficiency.

Mold carriers and fixtures employ mechanical clamping mechanisms—hydraulic, pneumatic, or mechanical—to securely grip molds. They interface with conveyor tracks or robotic systems for transportation between stations. Precision alignment features ensure accurate positioning at each processing stage. Load-bearing structures distribute weight evenly to prevent deformation during movement. The clamping force, typically 10–50 kN, holds the mold securely, while positioning accuracy of ±0.05 mm and repeatability of ±0.02 mm ensure consistent placement. Operating within -20°C to 80°C, these components are designed for continuous operation in automated production lines.
