Design And Analysis Of The Clamping Systems For All Electric For All Electric Injection Molding Machine

Along with the development of economic prosperity, plastic industry obtained fast development in our country, especially used in automobile, electronics,electrical appliances etc.Various industries required plastic products accuracy, shape, function and cost have a higher precision, so need to improve injection performance. Clamping system is one of the key parts for all electric injection molding machine, the structure and properties of injection molding machine directly affect plastic dimension precision and quality,it also influence the whole machine working performance and production capacity. So improvement the clamping system's performance is imminent, we should guarantee the mould speed, precision and the mould clamping force to meet these related products of the production.In one word, our country should improvement clamping system's core technology.In this paper we found existing clamping system's advantages and disadvantages,and then put forward two new clamping system mould,2K-H differential gear trains clamping systems and the closed load pattern clamping systems of all electric injection molding machine.Based on design the 2K-H differential gear trains clamping systems of all electric injection molding machine and analysis power flow of differential gears.2K-H differential gear trains clamping systems make asynchronous motors and step-motor generated through two degrees of freedom ZUWGW 2K-H differential gear trains, this finally produce programmable output motion, while asynchronous motors and stepping motor hybrid drive, which effectively instead of high-power stepping motor, Thus can achieve high clamping force, high efficiency, high speed, low energy consumption.Based on design the closed load pattern clamping systems of all electric injection molding machine and analysis enclosed differential gear trains.The improvement of this institutions in using enclosed differential gears and using stepper motors load on differential gears loading device,and this can make big power flow in the whole enclosed gear trains,which also can make the stepping motor provides small power,but achieve high clamping force and low energy consumption.
