  • Two-stage hydraulic booster device for a mold functional component
    Patent number: 10052805
    Abstract: A two-stages hydraulic booster device for mold functional components includes a first hydraulic control one-way valve serially connected between the solenoid directional control valve and the pumping chamber of the supercharger via a first oil passage; a second hydraulic control one-way valve serially connected between the solenoid directional control valve and the pressure accumulating chamber of the supercharger via a second oil passage. The solenoid directional control valve simultaneously supplying oil to the first and second hydraulic control one-way valves via the first and second oil passages, respectively, and the pressure for opening the second hydraulic control one-way valve is larger than that of the first hydraulic control one-way valve, thereby moving the back pressure formed in the first oil passage to open the second hydraulic control one-way valve to drive the piston to transform the low pressure oil into high pressure oil to move the mold functional components.
