INTEGRATED HYDRAULIC SYSTEM AND TIRE VULCANIZING MACHINE

WIPO Patent Application WO/2022/228257

A1

An integrated hydraulic system and a tire vulcanizing machine. The integrated hydraulic system comprises a hydraulic pump source, a control valve block and an execution mechanism. The execution mechanism comprises an integrated oil cylinder (31) and a liquid filling unit (32). The integrated oil cylinder (31) comprises a cylinder body (311), a static piston rod (312) and a movable piston rod (313). The static piston rod (312) is fixedly arranged within the cylinder body (311). The movable piston rod (313) is slidably arranged within the cylinder body (311), and is slidably matched with the static piston rod (312). A rodless cavity (314) and a rod cavity (315) are provided between the movable piston rod (313) and the cylinder body (311). A fast-intake cavity (316) is provided between the movable piston rod (313) and the static piston rod (312). The liquid filling unit (32) is configured to supply hydraulic oil to the rodless cavity (314). The hydraulic pump source separately supplies hydraulic oil to the rod cavity (315), the rodless cavity (314) and the fast-intake cavity (316) by means of the control valve block.
