Control loop for action of disc mechanism of full-automatic disc injection molding machine

The utility model discloses a control loop for action of a disc mechanism of a full-automatic disc injection molding machine. A motor drives a duplex vane pump; a large pump of the duplex vane pump is communicated to a first distribution valve element through a first A-type mechanical hand-operated valve, a small pump of the duplex vane pump is communicated to a second distribution valve element through a second A-type mechanical hand-operated valve, and the first distribution valve element is communicated to a shoe last pressing oil cylinder assembly through a first B-type mechanical hand-operated valve and communicated to a die assembly oil cylinder assembly through a second B-type mechanical hand-operated valve. The second distribution valve element is communicated with a gland oil cylinder assembly through a third B-type mechanical manual valve and a first tubular hydraulic control one-way valve, communicated with a bottom core lifting oil cylinder assembly through a second B-type mechanical manual valve
