& nbsp; The J339 tilting gravity casting machine is composed of a main machine (including the base, bed, left and right opening and closing mechanisms, lower core pulling mechanisms, and front and rear core pulling and inserting mechanisms), a hydraulic system (including hydraulic power station, valve group, pipeline system, etc.), a mold cooling system, and an electrical control system.Machine structureThis machine is mainly composed of a base, a bed, a left and right opening and closing type, a lower core pulling mechanism, a front and rear core pulling mechanism, a hydraulic control system, a cooling system, and an electrical control system. It adopts electrical and hydraulic joint control and has three working programs: jog, manual, and automatic, which are respectively suitable for machine adjustment and continuous production.● Bed: The bed is a square frame made of steel plates and various types of steel welded together, with other parts of the machine installed on the bed. Under the action of the tilting mechanism, the bed can tilt forward as a whole up to a maximum of 90 degrees;;Left and right opening and closing mechanisms: divided into left and right parts, installed at the left and right ends of the bed respectively, used for the left and right opening and closing of the mold. The shaped oil cylinder is fixed on the shaped bracket, and the shaped oil cylinder adopts a positive installation method, guided by four guide rods, and connected to the dynamic plate together with the piston rod of the oil cylinder;● Lower core pulling and inserting mechanism: it is installed at the middle and lower part of the bed to provide power source for the mold with lower core pulling casting. The lower core pulling and inserting mechanism can be adjusted forward and backward;Front and rear core pulling and inserting mechanisms: The front and rear core pulling and inserting mechanisms are installed on the front and rear sides of the middle of the bed, providing power source for the mold with core pulling castings. The center height of the core pulling cylinder can be adjusted by replacing the cushion block;Adopting a constant pressure variable axial piston pump to ensure automatic adjustment of system pressure and flow, saving energy. The system mainly consists of oil cooler, hydraulic pipeline, oil tank, return oil filter, hydraulic valve and valve plate, motor, etc.The bed tilting speed is automatically controlled by the electrical control system in stages based on the set proportional valve opening parameters, achieving automatic adjustment of the rack tilting speed.The core of the electrical control system adopts a PLC control device, and the parameter setting and display use a color touch display unit to complete the functions of displaying the working status and faults of the metal mold casting machine, as well as setting and modifying parameters. technical parameter Name& nbsp; & nbsp; callCompanytechnical parameterLeft and right panel dimensionsmm900X600Left and right combined cylinder strokemmfive hundred and fiftyMinimum spacing between left and right shaped platesmmfour hundredMaximum spacing between left and right shaped platesmmone thousand and five hundredLeft and right opening forceKNeightyFront and rear core pulling strokemmtwo hundredFront and rear core pulling forceKNsixtyLower core pulling strokemmtwo hundred and sixtyLower core pulling forceKNone hundred and twentyTilt angle°0~90Hydraulic system working pressureMPatenOil pump motor powerkWfifteenTotal weight of the machinekgeight thousandMachine (host) overall dimensions (LxWxH)mm4220X2330X2440, when standing on the side, H=4340
