Stamping Parts with Automatic Mold-Loading Equipment

Automatic mold-loading equipment streamlines the process of installing and aligning stamping molds into presses, addressing a major bottleneck in stamping production—traditional manual mold changes can take 2-4 hours, causing significant downtime. This equipment automates mold transport, positioning, and clamping, reducing changeover time to 15-30 minutes, and ensuring precise mold alignment to prevent part defects.

The system typically includes three components: a mold storage rack (holding 5-20 molds), a transfer cart (electric or hydraulic, moving molds between the rack and press), and a press-mounted clamping system (quick-change clamps or magnetic chucks). The transfer cart uses laser positioning to move molds (up to 50 tons) with ±1mm precision, while the clamping system secures the mold to the press’s bolster plate—quick-change clamps can lock the mold in place in 2 minutes, compared to 30 minutes for manual bolts. For example, an automatic mold-loading system for a 2000kN stamping press used in automotive suspension part production reduced mold changeover time from 3 hours to 20 minutes, increasing press utilization from 60% to 85%.

Precision alignment is ensured via guide pins and sensors: the mold’s locating pins fit into the press’s bolster bushings, and laser sensors verify alignment, correcting any 偏差 (deviation) via the cart’s hydraulic adjustments. This prevents mold misalignment, which can cause burrs, dimensional errors, or mold damage. A stamping plant producing kitchen hardware reported that automatic mold loading reduced part rejection rates from 4% to 1.5% by eliminating alignment errors. For manufacturers with multiple mold changes daily, this equipment is a game-changer, minimizing downtime and maximizing production efficiency.
