The system is for automatic horizontal flaskless molding machine, including two sets of systems, mainline system and sub-line system.
Hydraulic cylinders of patrix and nowel in mainline system are controlled by flow control valve, slowing down when activated and stopped, achieving precise halting position, guaranteeing the quality and acceptability of sand molds. Main station and valve stations are separated by design in sub-line system, making it easy to install pipelines. Pushing cushion cylinder is controlled by proportional selector valve, meeting different speed needs in different stages of stroke. The activation and halt are stable and without impact.
