Overview of the working principle of the cold core box core shooting machine

ZH110L series cold box sand core shooting machine is the sand core moulding machine that evenly shoots sand into core box by sudden expansion of compressed air(the required sand fully mixed in proportion by sand mixer and needed resin sand before shooting), and then blows triethylamine gas into core box and makes moulding sand cured and formed by gas blowing device. Through this processing, the sand core is no need to heat with high curing speed, the castings with bright and clean surface and high precision. This processing represents the mainstream of today''s sand core making technology, has been widely used in foundry workshop of automobile, spare parts, engine, all
kinds of valves, electrical accessories these industries.
Performance and Characteristics:
1. Suitable for rapid curing of the resin sand of cold core box bytriethylamine or CO2, high efficiency, low cost and low gas evolution to sand core or sand moulds.
2. PLC program control, LCD screen parameter setting, process display, fault diagnosis,
manual/automatic/point operation, automatic digital display temperature control.
3. Adopt vibration pressurization sand shooting technology, high rigidity and precision, finish good, no waste, less rest sand in sand shooting head.
4.Precise guiding device for sand cylinder, amine plate and vertical motion. after shooting sand, automatically blown, cured and cleaned. Remove mould automatically to take out sand core.
5. Equipped with high performance SL series triethylamine generator, highproduction efficiency, little amine, no pollution, no need for secondary blowing.
6. High frequency quenching hard chromium guide rail with high precision and long service life, the mold can be multi-directional, sealing automatic door to improve the operating environment.
7.All movement and core shooting is air operated or driven by pneumatic orhydraulic together.
