The overturning punching machine is one of the key equipment used in the resin sand molding process. Its function is to separate the pattern from the sand mold. The success or failure of this process directly affects the quality of the molding sand. The overturning punching machine is a kind of equipment suitable for resin sand or other self-hardening sand molding lines. Its working principle is scientific and the operation is simple, and it is widely used in the foundry industry.

Overturning die-cutting machine is mainly used in resin sand and other self-hardening sand molding lines to complete the inversion and drafting of the casting mold. The fuselage is composed of machine base, roller, hydraulic system and electric control cabinet, which is controlled by PLC. Positioning detection and mold ejection detection are completed by proximity switch and photoelectric switch respectively. The vibration motor is used to assist the mold release, and the shock force can be adjusted.

The full hydraulic flexible control system is adopted for the overturning ejector, which not only makes the whole machine move smoothly, but also continuously adjusts the ejection cycle, which is convenient for the synchronous adjustment of the entire casting production line. It is suitable for molding resin sand and water glass sand with or without box, turning over the box and removing the mold in the core-making production line. The running noise is low, and it can realize automatic or single action.
