Abstract

The invention relates to a servocontrol semi-solid state magnesium alloy high speed injection molding machine which comprises a clamping mechanism, an injection mechanism, a hydraulic mechanism, an electrical mechanism and a stander; wherein, an injection oil cylinder in the injection mechanism is provided with a hollow floating piston, and a charging system is provided with a feeding screw rod component which can form semi-solid state magnesium alloy organization form; the hydraulic mechanism comprises a cartridge valve and a high response energy accumulator, a high speed injection speed control system is provided with a high frequency response servovalve at the oil outlet side of the injection oil cylinder, and two pressure sensors PS1 and PS2 are arranged at the oil inlet side and the oil outlet side of the injection oil cylinder so as to detect the system pressure in real time; the electrical mechanism is provided with a high speed CPU module used for controlling the high speed injection speed, so as to realize real time closed-loop control. The servocontrol semi-solid state magnesium alloy high speed injection molding machine has the advantages of compact structure, low manufacturing cost, small volume, low energy consumption, high control accuracy, easy debugging and high speed injection, and can make closed-loop control on the injection speed, the dwell pressure and theplasticization back pressure.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a servo-controlled semi-solid magnesium alloy high-speed injection molding machine, which belongs to the field of metal alloy material thermoforming processing technology and equipment. Background technique [0002] In the production and application of magnesium alloy materials, hot chamber and cold chamber die casting with high technological maturity account for the largest proportion of various magnesium alloy forming technologies. Magnesium alloy die-casting requires extremely high injection speed, so there will inevitably be turbulent flow of molten metal and gas entrainment in the mold, resulting in hole defects inside and on the surface of the workpiece, resulting in low product strength, no heat treatment, and poor air tightness , In addition, it also leads to difficulties in mold design and difficulty in controlling the yield rate; secondly, melting magnesium alloys also in...
