Description

Three-die-opening overturning core shooting machine

Technical Field

The utility model belongs to the technical field of core making equipment, and particularly relates to a three-die-opening overturning core shooter.

Background

The core shooter adopts precoated sand to prepare cores, utilizes compressed air to evenly shoot molding sand into a sand box for pre-compaction, and then applies pressure for compaction. The core shooter has wide application in recent years, the molding of the core shooter can reduce the waste of casting heads, and the coated sand after casting has good collapsibility, thereby being beneficial to sand removal. The core shooter has high production efficiency and accurate sand mould size, and can properly reduce the processing amount; simple operation, high casting yield and more casting factories favor the use of a core shooter for molding.
