With energy saving consumption reduction becoming a national strategy, energy saving of injection molding machine has also been widely concerned. Reducing the daily operation cost is one of the main benefits of most companies at present. In the field of conventional injection molding machine, there are two mature ways to save energy for motor, frequency converter servo motor, among which servo motor is more more widely accepted.
Introduction of injection molding machine
Injection molding machine is also known as injection molding machine injection machine. Many factories call it pi Ji, injection products call beer parts. It is the main molding equipment that makes thermoplastics thermosetting materials into various shapes of plastic products by using plastic molding mold. According to the arrangement of injection device mold locking device, injection molding machine can be divided into vertical, horizontal vertical horizontal compound type.
The working principle of the injection molding machine is similar to that of the syringe for injection. It is a technological process in which the plasticized plastic in the molten state (i.e. viscous flow state) is injected into the closed mold cavity with the help of the thrust of the screw ( plunger), the product is obtained after solidification finalization.
Injection molding is a cycle process, each cycle mainly includes: quantitative feeding, melting plasticizing, pressure injection, mold filling cooling, mold opening taking. Take out the plastic part then close the mold for the next cycle.
Servo energy-saving series injection molding machine is equipped with high-performance servo variable-speed power control system. In the molding process of injection molding machine, different pressure flow are output at different frequencies, the pressure flow are precisely controlled in closed-loop, so as to realize the high-speed response, matching automatic adjustment of servo motor to the energy demand of injection molding machine.
1. Adopt excellent performance servo controller, servo motor other energy-saving devices.
2. Sensitive servo control system, quick start response time is only 0.04s
3. Servo motor hydraulic system constitute a closed loop control, compared with the traditional model, the repetitive accuracy is greatly improved
4. Reduce the impact of unlocking die, extend the service life of mechanical parts die
5. It can save 20% - 80% power than traditional injection molding machine under ideal working condition
6. The calorific value of the system is far lower than that of the traditional injection molding machine, which saves about 30% of the cooling water consumption prolongs the service life of the oil way seals hydraulic parts
7. The noise of the whole line is lower than that of the traditional injection molding machine
