Embodiment Construction

[0013] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the high-speed injection molding machine hydraulic control system provided by the present invention includes a low-pressure large-flow pump 1, a high-pressure small-flow pump 2, a one-way valve 3, a hydraulic control sequence valve 4, an overflow valve 5, and a three-position four-way reversing valve 6. The first hydraulic control check valve 7, the second hydraulic control check valve 8, the hydraulic cylinder 9, the oil tank 10 and a plurality of accumulators 11.

[0015] The oil inlet of the high-pressure and small-flow pump 2 is connected to the oil tank 10, and an oil filter 12 can be set at the oil inlet of the high-pressure and small-flow pump 2, and the oil is filtered through the oil filter 12, thereby ensuring that the oil enters the system. The cleanliness protects the safety of other equipment in the sys...

Abstract

The invention relates to the technical field of high-speed injection molding machines, in particular to a hydraulic control system of a high-speed injection molding machine. The hydraulic control system of the high-speed injection molding machine comprises a low-pressure large-flow pump, a high-pressure small-flow pump, a check valve, a hydraulic control sequence valve, an overflow valve, a three-position four-way reversing valve, a first hydraulic control check valve, a second hydraulic control check valve, a hydraulic cylinder, an oil groove and multiple energy accumulators. The hydraulic control system of the high-speed injection molding machine is simple in structure and convenient to operate, lowers cost and improves the work efficiency. Through the double-pump oil supply manner, the injection molding time can be shortened, and the injection molding efficiency is improved. Besides, through cooperative use of the small-flow hydraulic pump and the energy accumulators, rapid movement of an executing element can be achieved.

Description

technical field [0001] The invention relates to the technical field of high-speed injection molding machines, in particular to a hydraulic control system for high-speed injection molding machines. Background technique [0002] Injection molding machine is the abbreviation of injection molding machine. It uses the thermoplasticity of plastics to gradually plasticize, melt and homogenize plastic particles under the dual effects of external heating and screw shearing, and then pass them through the nozzle at high speed and high pressure. Quickly inject into the cavity of the mold, and form plastic products of various shapes after holding pressure, cooling, solidifying and shaping. High-speed injection molding machines have the advantages of high shear speed and short injection cycle, so they are widely used. However, the structure of the existing high-speed injection molding machine hydraulic control system is often complex, and the control effect is not good, it is not easy t...
