Haiying servo energy-saving injection molding machine is equipped with high-performance servo variable speed power control system, and equipped with rotary encoder and power sensor respectively to feedback the flow and pressure, high-performance synchronous servo motor by changing the speed and torque to make the corresponding flow pressure adjustment, closed-loop control of pressure flow. The servo motor can match and automatically adjust the energy demand of injection molding machine. Precision speed and pressure control is realized (mode-locking, injection, ejector full machine closed loop servo control greatly improves response speed, repeatability accuracy within.0.5%; The pressure holding action is tested for 8 seconds, and the pressure error is not more than 6Kg). Compared with the traditional injection molding machine, the repetition accuracy is better, the response speed is faster, the energy saving effect is more obvious, the power can be saved by 30%-70%, and the effect is more significant for the products with long pressure holding time and high precision. The economic benefit is obvious. The servo motor control system with fast response and stable performance is equipped with high-precision and sensitive pressure feedback device to form closed-loop pressure precision control, which can provide customers with good product stability. Servo energy-saving injection molding machine to reach the output of only 0.06S, compared with the traditional injection molding machine response speed is significantly faster, effectively shorten the cycle, improve production efficiency.

In addition, the reduction of the heat of the machine and the further reduction of the hydraulic oil temperature can reduce the amount of cooling water by about 35%, reduce the noise around the machine, strengthen the stability of the machine, increase the service life of the hydraulic oil and seals, so that the cost of machine use and maintenance is greatly reduced, and it also meets the current international strict environmental requirements.

Comparison between positive pressure type and toggle type ① Positive pressure type clamping force F=P cylinder ×S cylinder, easy to adjust the clamping force, but after the pressure is determined, it can not be overloaded, such as PMAX=140Kg/ca. In addition, the elbow injection molding machine is generated after the connecting rod mechanism force increases, so it can generally be overloaded by more than 10%. Due to the structural relationship, the general capacity of the direct pressure type is greater than the elbow type, and the price of the automatic injection molding machine is especially suitable for deep container products. The elbow type rigidity is better than the direct press, because the high pressure lock mode, the elbow type is generated after the deformation of the cast steel, when the overload, because the elastic modulus of the hydraulic oil and the cast steel is about 10 times, so in the same case, the elbow type injection molding machine produced by the flash will be greatly reduced. (1) Elbow injection molding machine because the clamping force is generated by the amplification of the force, and the pressure after the locking is high, the pressure can be discharged during the injection molding and pressure holding process, and the direct pressure injection molding and pressure holding always maintain high pressure, and the diameter of the direct pressure clamping cylinder is much larger than the elbow type, therefore, the service life is long, the service life is long, the service life is long.
