Machine characteristicsThis machine is mainly composed of a base, a bed, left and right opening and closing mechanisms, a lower ejection mechanism, an upper core pulling mechanism, a lower ejection mechanism, a front and rear core pulling mechanism, a hydraulic control system, an electrical control system, and a cooling system. It adopts electrical and hydraulic joint control and has two working systems: manual and semi-automatic circulation, which are respectively suitable for machine adjustment and continuous production;The bed is a square frame welded from steel plates and various types of steel, and the other parts of the machine are installed on the bed. Under the action of the tilting mechanism, the bed can tilt forward as a whole up to a maximum of 45 degrees;;Left and right opening and closing mechanisms: The opening and closing mechanism is divided into two parts: left and right, used for the left and right opening and closing of molds. Two fitting oil cylinders are fixed on the left and right sides of the fitting bracket, and the fitting bracket is fixed on the bed. The combined cylinder adopts a formal installation method and is connected to the dynamic plate through the piston rod of the oil cylinder; The middle of the two combined oil cylinders is a guide rod, which is a hollow structure. The ejection oil cylinder is installed at the rear of the guide rod;● Upper core pulling and inserting mechanism: The upper core pulling cylinder is installed on the frame connected to the clamping bracket, providing power source for the mold with upper core pulling castings;● Lower ejection mechanism: located in the middle of the bed, fixed on the crossbeam guide rails on both sides of the bed, consisting of two parts: ejection cylinder and guide mechanism, and driven by the oil cylinder to complete the ejection action of the casting;Front and rear core pulling and inserting mechanisms: The front and rear core pulling and inserting cylinders are installed on the frame connected to the clamping bracket, and the core pulling cylinders can be adjusted left and right within a certain range, providing power source for molds with core pulling castings;Adopting a constant pressure variable axial piston pump to ensure automatic adjustment of system pressure and flow rate, saving energy;Equipped with a mold cooling circuit for automatic control of cooling time; The cooling time parameters can be set and modified on the human-machine interface;The electrical control system consists of two parts: a human-machine interface and a PLC lower control device. The human-machine interface completes monitoring and management functions such as displaying machine working status and fault alarms, setting and modifying parameters. technical parameter Name& nbsp;& nbsp; calltechnical parameterCompanyLeft and right combined cylinder strokefour hundredmmMinimum spacing between left and right shaped platesfour hundredmmMaximum spacing between left and right shaped platesone thousand and two hundredmmLeft and right opening force40X2=80KNCenter height of left and right combined cylinders265 (to the upper plane of the bed)mmLeft and right ejection strokefiftymmLeft and right top outputfortyKNFront and rear core pulling stroketwo hundredmmFront and rear core pulling forceseventeenKNCenter height of front and rear core pulling cylinders165-465 (divided into 6 gears with a spacing of 50mm between each gear)mmUpper core pulling strokefive hundredmmUpward core pulling forceforty-threeKNMinimum spacing between upper platessix hundred and fiftymmMaximum spacing between upper platesone thousand one hundred and fiftymmLower ejection mechanism travelone hundredmmEjection force of the lower ejection mechanismsixty-two point eightKNTilt angle0~45°Hydraulic system working pressureeightMPaOil pump motor powerseven point fivekWTotal weight of the machinefour thousandkgOverall dimensions of the machine (host)3500X2420X2760mm
