Research On High Dynamic Stability Of New Two-Color Injection Molding Machine Hydraulic System

In two-color injection molding machine, hydraulic control system occupies a very important position, is the double color injection molding machine is very important core control part, double color injection molding machine hydraulic control system dynamic stability performance, directly affects the performance of the whole running double color injection molding machine. Aiming at the existing defects of hydraulic system of double color injection molding machine, subject to the "high efficiency, safety, stability, energy saving" as the goal, the development of a new second generation of two-color machine hydraulic system. Study on clamping force production to Haitian company 160 tons rotary table type two-color injection molding machine hydraulic system as the object, conducts the research to the hydraulic system of injection mold, hydraulic system, turntable control hydraulic system dynamic stability and temperature preheating mechanism etc.. In order to facilitate the distinction and the macro development of Haitian company, need to be improved and upgraded machine models for 1A1600II bj.In two-color injection molding machine, hydraulic control system occupies a very important position, is the double color injection molding machine is very important core control part, double color injection molding machine hydraulic control system dynamic stability performance, directly affects the performance of the whole running double color injection molding machine.Aiming at the existing defects of hydraulic system of double color injection molding machine, subject to the "high efficiency, safety, stability, energy saving" as the goal, the development of a new second generation of two-color machine hydraulic system. Study on clamping force production to Haitian company 160 tons rotary table type two-color injection molding machine hydraulic system as the object, conducts the research to the hydraulic system of injection mold, hydraulic system, turntable control hydraulic system dynamic stability and temperature preheating mechanism etc.. Analysis of injection of double color injection molding machine control, model control, hydraulic turntable control of the paper, and the establishment of physical model, the corresponding mathematical model, control model and simulation analysis model. The stability simulation analysis and optimization of a new hydraulic control principle. The prototype was tested, and the experimental data are compared and analyzed, two optimization of hydraulic control system. Finally, the temperature of preheating scheme, preheating mechanism of system analysis, pressure temperature preheating the new scheme can be adjusted without additional preheating device, perfect unity and realization method of the control of the work mechanism of rapid action and oil temperature preheating, resulting in the precondition of not increasing oil amount, improve the use efficiency of oil liquid.
