& nbsp; J452 200Kg aluminum alloy low pressure casting machine is a general equipment for aluminum alloy low pressure casting, which can be widely used in the production of small and medium-sized aluminum alloy complex castings in automobile, motorcycle, electric power fittings, instruments, textile machinery and aerospace industry. The equipment has a simple structure, reliable operation, high degree of automation, and good process adaptability. This model of low-pressure casting machine is affordable and has a high cost-effectiveness& nbsp;& nbsp; The machine is mainly composed of the main engine, hydraulic system, melt pool insulation furnace, liquid level pressurization device, electrical control system, and mold cooling system. Performance characteristicsThe clamping mechanism adopts four column guidance and is equipped with two sets of left and right static mold core pulling mechanisms (four sets of core pulling mechanisms can be selected);The casting is ejected in a reverse ejection mode;The insulation furnace is fixed, and the static template of the forming mechanism is rigidly connected to the insulation furnace, effectively shortening the length of the metal liquid conveying channel;● Equipped with multiple mold cooling circuits, with optional cooling media and automatic control of cooling time. Cooling parameters can be set and modified;Melting pool type insulation furnace, radiation heating. Control adopts PID+SCR, rated temperature range: 680-750 ℃, temperature control accuracy:± 5℃；The electrical control system consists of two parts: a PLC control device and a human-machine interface. The control system completes the host action control, liquid level pressurization control, and mold cooling control of the low-pressure casting machine. Fully automatic control of the low-pressure casting machine can be achieved, and the pressurization process parameters of the low-pressure casting machine can be set, modified, and displayed;The liquid level pressurization device adopts imported pneumatic proportional valves and high-precision pressure sensors to achieve pressure detection and real-time closed-loop feedback control in the insulation furnace, with PID adjustment method. It has functions such as multi-level linear pressurization, automatic tracking and setting of pressurization curve, insulation furnace leakage compensation, and liquid level compensation. High pressure control accuracy and good repeatability ensure the stability and consistency of the low-pressure pouring process, effectively improving the yield of castings. technical parameter Serial numberParameter NameParameter valueCompanyoneHolding Furnace Capacity (AL)two hundredKgtwoStatic template size1400X1200mmthreeMoving template size700X700mmfourSpacing between columns900X900mmfiveMoving template travelsix hundredmmsixOpening forceone hundred and seventeenKNsevenCombining forceeightyKNeightMinimum opening gearthree hundredmmnineMaximum opening gearnine hundredmmtenHydraulic system working pressuretwelveMPaelevenCore pulling stroketwo hundredmmtwelveCore pulling forceseventyKNthirteenOil pump motor powerelevenKw
