Technical background
Plastic products now occupy suitable proportion in each side such as industry, agricultural and people's lives, and in recent years, international and domestic molding machine industry was flourish, make rapid progress, and the level of plastics machinery development is subjected to people's attention day by day.Because energy-conservation and environmental protection more and more is subjected to the great attention of countries in the world, makes energy-saving plastic machinery become an important development direction of current plastics machinery.
At present, the fluid pressure type injection machine not only can't satisfy high forming technique requirement, and also have many other deficiencies: the control accuracy of each mechanism action is relatively low, and gearratio is accurate not as machine driving; When the oil temperature changed, oil viscosity also can change, and influences the stability of system; Hydraulic oil in the hydraulic system produces a large amount of heats when the pump of flowing through, valve and pipeline, cause oily temperature rise, and therefore the warm operate as normal that will influence hydraulic system when too high of oil, need take the heat of hydraulic oil out of by oil cooler, consumes big energy; The noise of hydraulic system is big, and the leakage of hydraulic oil simultaneously also is difficult to avoid, and has brought influence to working environment; Oil cooler need lead to cooling water takes away heat in the hydraulic oil, causes the waste of water resource; The frequent replacing of hydraulic oil and hydraulic pressure components and parts increases cost.
Therefore, traditional hydraulic-driven is substituted by other more advanced type of drive.Full electric injection molding machine just progressively substitutes the hydraulic-driven injection machine as high-tech electromechanical integrated product of new generation, becomes the inexorable trend of injection machine development.But full electric injection molding machine is compared obviously not enough in addition with fluid power system at aspects such as active force, overload capacity.Its disadvantage is that cost is too high, and general medium-sized and small enterprises can't bear, and the domestic market is still immature at present.
Summary of the invention
The utility model has solved the fluid pressure type injection moulding machine oil temperature height that prior art exists, and precision is low, and noise is big, easy oil leakage, energy consumption big or full electric injection molding machine active force and overload capacity deficiency, problems such as cost height provide a kind of oily temperature lower, precision is higher, noise is little, not easy oil leakage, and energy consumption is little, active force and overload capacity height, the high efficient servo injection machine that cost is lower.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise injection moulding, preformed hydraulic circuit, described injection moulding, preformed oil circuit one end connect oil pump and fuel tank, and the other end connects preformed hydraulic motor, injection moulding oil cylinder and other hydraulic jack or motor by electromagnetic switching valve respectively; Described oil pump connects servomotor, and described servomotor connects drive system.Wherein, adopt the driven by servomotor hydraulic circuit, both had the big and strong advantage of overload capacity of hydraulic injection molding machine active force, had electric injection molding machine precision height again, noise is little, not easy oil leakage, and the oil temperature is low, the characteristics that energy consumption is little.
As preferably, described drive system is connected with control system by converter, and described control system is provided with man-machine interface, logic controller, the centre of motion and servo-drive.Wherein, control system can improve control accuracy of the present utility model, can satisfy the high forming technique requirement of injection machine.
As preferably, described control system is provided with temperature control unit and sensor.Wherein, temperature control unit and sensor can be controlled the temperature of hydraulic circuit, reduce the oil temperature of hydraulic circuit, reduce energy consumption of the present utility model.
As preferably, described servomotor is the rare earth permanent magnet AC servo motor.
As preferably, be connected with the folding mould oil cylinder by electromagnetic switching valve in described injection moulding, the preformed hydraulic circuit, the mode transfer hydraulic motor, oil cylinder, whole mobile oil cylinder are moved back in the jacking top.
Therefore, it is lower to the utlity model has oily temperature, and precision is higher, and noise is little, not easy oil leakage, and energy consumption is little, active force and overload capacity height, characteristics such as cost is lower.Wherein, adopt the driven by servomotor hydraulic circuit, both had the big and strong advantage of overload capacity of hydraulic injection molding machine active force, had electric injection molding machine precision height again, noise is little, not easy oil leakage, and the oil temperature is low, the characteristics that energy consumption is little.Wherein, control system can improve control accuracy of the present utility model, can satisfy the high forming technique requirement of injection machine.Wherein, temperature control unit and sensor can be controlled the temperature of hydraulic circuit, reduce the oil temperature of hydraulic circuit, reduce energy consumption of the present utility model.
