The invention discloses a filling valve of a vertical type injection molding machine. The filling valve of the vertical type injection molding machine comprises a valve body and a valve element, wherein the valve body is provided with an oil inlet hole and an oil outlet hole, the valve element is arranged inside a cavity of the valve body, a valve element cylinder sleeve is fixedly arranged on the lateral face of the valve body, a pressure oil inlet hole is formed in the lateral face of the valve element cylinder sleeve, the valve element comprises a front guide end and a sealing end, a valve element piston is fixedly arranged at the front guide end, a reset spring is arranged at the side, close to the front guide end, of the valve element piston, and the other end of the reset spring is connected with the valve body. The filling valve of the vertical type injection molding machine comprises the valve body, the valve element and the valve element cylinder sleeve, before a piston inside a hydraulic oil cylinder moves downwards, pressure oil is injected into the valve element cylinder sleeve in advance, the valve element is in a completely open state, and therefore the purposes of improving the oil feeding speed of the hydraulic oil cylinder and improving the injection molding efficiency of the injection molding machine are achieved.
Description
Technical field
The present invention relates to a kind of liquid-filling valve, particularly a kind of vertical injection molding machine liquid-filling valve.
Background technique
Liquid-filling valve generally comprises valve body and spool, between hydraulic oil container and hydraulic jack, play unidirectional non-return effect, the oil outlet of valve body is connected with hydraulic jack oil inlet hole, when the piston in hydraulic jack moves downward, can pull out vacuum inhales spool to hold, and by the hydraulic oil inhalant liquid compressing cylinder in hydraulic oil container, and piston is upwards made hydraulic oil in when motion pressurization hydraulic jack spool top is pressed on valve body oil outlet sealing, prevent hydraulic oil adverse current.
The hydraulic oil container of vertical injection molding machine is larger apart from the perpendicular distance of liquid-filling valve; therefore; hydraulic oil in fuel sucking pipe has larger gravitational potential energy; to closing direction, pull liquid-filling valve spool; depend merely on the open mode that pull of vacuum that piston in hydraulic jack moves downward generation is not sufficient to keep liquid-filling valve spool, particularly, when piston has just started to move downward, spool is usually also in closed state; reduce the oil-feed speed of hydraulic jack, affected the injection moulding efficiency of injection machine.
