Abstract

The invention relates to a novel hydraulic control system of a die casting machine. The system comprises a die adjustment motor and a shutoff oil cylinder. The die adjustment motor is connected with a die adjustment valve, the shutoff oil cylinder is connected with a shutoff valve, the die adjustment valve and the shutoff valve are connected through a main circuit, branch circuits, namely a first branch circuit, a second branch circuit and a third branch circuit, are arranged on the main circuit, and a first electromagnetic valve and an energy storing device are arranged on the first branch circuit. Energy is saved, a hydraulic pipeline can be protected, pressure and flow precision can be improved, speed is increased, efficiency is improved, and noise is reduced.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system of a die-casting machine. Background technique [0002] The hydraulic system of traditional die-casting machines is a combination of motor and oil pump composed of ordinary motors and quantitative pumps. In the hydraulic system of quantitative pumps, the oil pump motor provides constant flow at a constant speed. In recent years, only pressure proportional valves have been added to the oil circuit. And flow proportional valve, and the pressure and flow required for work are adjusted by the pressure proportional valve and flow proportional valve, and the pressure or flow is controlled by adjusting the opening of the pressure or flow proportional valve. The excess hydraulic oil returns through the relief valve. This process is called high-pressure interception, and the energy loss caused by it is generally about 50%. Another 20% is wasted energy by overflow losses and heat g...
