Abstract

The invention discloses a hydraulic mechanism of a full-automatic polypropylene forming machine, which comprises a PLC controller, coils a, b, c, e and g of a solenoid valve, an oil cylinder 5, an oil cylinder 6, an oil pump 21 and an oil pump 22; the whole mechanism controls the solenoid valve through the PLC controller; after being electrified, the coils a, c, e and g move forwards quickly; after being electrified, the coils b, c, e and g move backwards quickly; after being electrified, the coils a, c and g move forwards slowly; after being electrified, the coils b, c and g move backwards slowly; after the coils a, d and g are electrified, a mould is locked; the oil of the oil cylinder 6 is supplied by the oil pumps 21, 22; the oil of the other four oil cylinders 5 is supplemented by automatic flow; and when the mould is locked, the five oil cylinders are pressurized at the same time. The hydraulic system is also provided with laminated-type guide check valves 7 and 8; and the hydraulic system of the full-automatic polypropylene forming machine is also provided with the laminated-type guide check valves 7 and 8, so that the locking force is increased by 20%.

Description

technical field [0001] The invention relates to a component of a fully automatic polypropylene forming machine, in particular to a hydraulic system of a fully automatic polypropylene forming machine, and belongs to the technical field of a fully automatic polypropylene forming machine. Background technique [0002] Polypropylene automatic molding machine is one of the commonly used molding machines in industry. Existing hydraulic system of polypropylene automatic molding machine, including PLC controller, solenoid valve coils a, b, c, d, e, f, g, oil cylinder 5, oil cylinder 6, oil pump 21, oil pump 22; the whole system is controlled by PLC The controller controls the solenoid valve, coils a, c, e, g are energized to move forward quickly; coils b, c, e, g are energized to quickly retreat; coils a, c, g are energized to move forward slowly; coils b, c, g When power is applied, the tool moves back slowly; coils a, d, and g are energized to lock the mold; oil cylinder 6 is sup...
