AI Technical Summary
Traditional injection mold cooling methods result in uneven mold temperature distribution, inconsistent product shrinkage, surface defects, long cooling cycles, complex maintenance processes, and increased downtime.
It adopts a dual cooling method of circulating water cooling and air cooling, combined with modular quick-release design and semiconductor refrigeration cycle. The coolant flow rate is adjusted by intelligent flow valve and temperature sensor, heat is discharged by negative pressure fan, and the semiconductor cooler is dynamically adjusted to achieve uniform mold temperature.
It significantly improves mold cooling efficiency, reduces product deformation and surface defects, shortens the cooling cycle, reduces energy consumption and maintenance costs, increases production cycle time, and achieves high production efficiency.
