Abstract

The invention is applied to a hydraulic system applied to a hydraulic automatic molding machine. A first motor is connected to a PQ pump, the first PQ pump is connected to a first one-way valve through a first filter, the first one-way valve is connected to a proportional directional valve, and the first PQ pump is provided with a proportional control valve provided with a pressure sensor; the proportional directional valve is connected to a die assembling oil cylinder through an oil pipe; a second motor is connected to a second PQ pump, the second PQ pump is connected to a second one-way valve through a second filter, the second one-way valve is connected to an energy accumulator, the energy accumulator is provided with a load, the energy accumulator is connected to a quick oil release valve provided with a primary pressure gauge, and the quick oil release valve is connected to the proportional directional valve; the proportional control valve of the first PQ pump acts a pressure to the die assembling oil cylinder through the first one-way valve and the proportional directional valve, so that the die assembling oil cylinder quickly finishes a die assembling movement. The hydraulic system has the characteristics of being novel in structure, effectively increasing the modeling speed of the molding machine, effectively improving the modeling precision of the machine tool and the percent of pass of the product and the like.

Description
