& nbsp; The J31 series metal mold gravity casting machine is mainly used for the production of aluminum alloy castings such as automotive cylinder heads. This series of metal mold gravity casting machines adopts a large number of world-renowned products in hydraulic and electrical aspects, effectively ensuring the reliability of the equipment& nbsp; Performance characteristics: The host is composed of left and right closing mechanisms, lower ejection mechanisms, upper flip compression mechanisms (optional), bed, base, and other parts. All hydraulic pump valves are imported branded products; The hydraulic pump adopts a variable displacement plunger pump to ensure constant system pressure, automatic flow regulation, and energy conservation; All oil cylinders are imported products, and high-temperature sealing components are used for the oil cylinders near the mold; The upward flipping and pressing mechanism adopts fast and slow flipping control to improve work efficiency and reduce impact. The machine can be equipped with multiple mold air and water cooling channels to achieve automatic cooling control through time control. The flow rate of each cooling channel can be manually adjusted. The setting of cooling parameters and the selection of working cooling channels can be completed in the human-machine interface. The electrical control system adopts imported PLC as the electrical control core to achieve manual and automatic control of the machine. Using an imported touchscreen human-machine interface as a monitoring display unit, it can visually and clearly display the working status of the machine and fault alarm information during operation, making it convenient to set and modify various parameters. technical parameter Name; callJ315J318J318CJZ318J319J3110CompanyLeft combined cylinder strokeone hundred and seventytwo hundredtwo hundred and fiftytwo hundredtwo hundred and fivetwo hundredmmRight combined cylinder strokeone hundred and seventytwo hundredtwo hundred and fiftytwo hundredtwo hundred and fivetwo hundredmmInner spacing between the rod ends of the combined cylinderseven hundred and fortyone thousand and two hundredone thousand and five hundredone thousand and two hundredone thousand one hundred and sixtyone thousand one hundred and thirtymmCenter height of combined cylinderone hundred and fortyfour hundred and fiftytwo hundred and fortyfour hundred and twenty-fivethree hundredthree hundredmmLower ejection strokeeightyfortyone hundredfortyone hundredone hundredmmLower top outputninety-eighttwo hundred and tenone hundred and twentytwo hundred and tenone hundred and twentyone hundred and twentyKNMotor powerelevenfifteenfifteenfifteenfifteenfifteenKWFront and rear core pulling strokeone hundred and seventyninety mmFront and rear core pulling center heightone hundred and fortyfour hundred and forty mmStroke of upper pressing mechanism one hundred and fifty MmUpward flipping mechanism angle ninety °
