Introduction of the Press Structure:
Mold opening/closing system adopts driving mode of traditional mechanical curing press' motor, reducer, crank gear, side link and beam. In order to lower press height, tilt-back open/close mold system is still adopted. Loader' up/down and in/out motion is realized with air cylinder. Unloader, top/bottom ring of center mechanism and SMO are actuated with oil cylinder. Stop position of top ring is controlled by linear displacement transducer. Only one motor and one pump are needed for HPU oil tank. The structure is simple and easy for operation.
Spacer of center mechanism for shaping is unnecessary. Position of top ring can be set directly on HMI, and positioning accuracy is high.
It' easy to control and adjust amount and speed of the force applied.
Hydraulic part and internal pressure part of center mechanism are completely independent from each other. Service life of internal pressure seal ring is prolonged.
Service life of oil cylinder is longer than that of water cylinder, which reduces maintenance frequency.
