compacting the molding sand, through injection The process of compaction and mold release makes the loose sand in the sand box compact, so that the sand mold has the necessary strength in the process of handling and pouring, and ensures the quality of the casting. The automatic vertical molding machine produced by sanzhuji, the amount of sand mold 200-220 boxes per hour, the whole process equipment adopts PLC centralized automatic control, high operating efficiency, good molding sand compactness, well received by the foundry industry.

The automatic vertical moulding machine is composed of body, rotating arm, ejection structure, shock compaction mechanism, rotating arm indenter part and pneumatic piping system, etc. It can be designed and manufactured according to customer''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s casting conditions.

 1. The fuselage is made of a solid hollow frame work piece. The upper part supports the indenter part of the rotating arm. When pressing, the rotating arm hooks the fuselage so that the pressing force is absorbed by the fuselage. The indenter part of the arm, the indenter is fixed on the rocker arm that can rotate, the indenter has a screw lift which can be adjusted to the distance from the indenter to the flask according to the height of the flask

 2. The swing arm is to control the reciprocating movement of the cylinder piston through the hand-pulled valve to realize the movement of the positive arm and the swing arm.

 3. The ejection structure consists of two ejection cylinders, connecting rod, balance shaft, ejection table, ejection rod, etc. When the ejection cylinder starts, the connecting rod is driven, and the balance shaft and ejection table make the four ejector rods eject at the same time Moulding from the sand box.

 4. Shock compaction structure. Adopt spring micro-vibration pneumatic compaction structure, compaction shock increases vibration. The clamping cylinder locks the vibrating cylinder when the mold is drawn, and the clamping cylinder is released when the mold is dropped.

 5. Pneumatic piping system: the input compressed air is removed by air filter to remove water and impurities in the compressed air, and then lubricating oil is injected through the lubricator to supply various pneumatic components and mechanisms, and the action of the machine is realized by the hand valve console .

 6. Air supply and lubrication. The machine is operated by air source as energy and oil as lubrication. The intake pressure and oil volume are adjusted by the pressure reducing valve and the oil regulating valve respectively. When the air source passes through the lubricator, the oil is sucked into the pipeline according to the siphon principle, and the mist enters the pipeline system for lubrication.
