Advanced Automatic Mold Flipping and Ejection System for Resin Sand Molding Casting Line

Product Description

Automatic flipping and ejection machine for casting

Our Automatic Mould Inversion & Pattern Withdrawal Machine is a critical piece of equipment in modern resin sand and self-hardening sand molding lines. It performs precise 180° flipping and synchronized pattern withdrawal after the sand has been compacted, ensuring the integrity of the sand mold while significantly improving production efficiency and worker safety. Ideal for both manual and fully automatic foundry systems.

Key Features

High-Precision Synchronized Lifting: Dual hydraulic cylinders with proportional control ensure dynamic synchronization accuracy ≤2 mm and steady-state accuracy ≤0.1 mm, preventing mold damage during pattern withdrawal.

Gentle 180° Inversion: Smooth flipping motion via servo-controlled reducer or hydraulic motor minimizes vibration, protecting delicate patterns and fragile molds.

Universal for Various Molding Processes: Compatible with flask (boxed) and flaskless (boxless) molding, suitable for horizontal parting, vertical parting, and core-setting operations.

Robust & Durable Construction: Heavy-duty steel frame with stress-relieved welding, designed for continuous operation in harsh foundry environments.

Smart Control System: Siemens S7-300 PLC + HMI interface enables one-button operation, fault diagnosis, and integration with automatic molding lines.

Customizable for Your Line: Adjustable stroke, speed, and clamping force based on pattern size, sand type, and production rhythm.

Product Technical Parameter

Typical Applications:

Resin Sand Molding Line

After compaction, the machine flips the sand box and withdraws the pattern to prepare for core setting or pouring.

Large Casting Production

Handles heavy patterns (e.g., engine blocks, pump housings, valve bodies) with high stability and repeatability.

Automated Foundry Workshop

Integrates with conveyors, robotic arms, and pouring systems for fully unmanned operation.

Pattern Maintenance & Inspection

Provides easy access to the pattern after withdrawal for cleaning, coating, or quality check.
