High-speed injection molding machines are all-electric motors, ordinary injection molding machines are hydraulic injection molding machines, and hydraulic injection molding machines are relatively slow in running speed. The servo motor used in the all-electric injection molding machine realizes the opening and closing mode, ejection and ejection, raw material injection and storage, etc., and the operation speed is fast and precise, which greatly improves or improves the production environment and production efficiency. However, servo electric injection molding machines now only have machines with clamping forces below 850 tons.
The high-speed injection molding machine is highly efficient. The molding process of the ordinary injection molding machine is: mold clamping - injection - cooling - storage - mold opening - mold - gap time; high-speed injection molding machine uses three-axis linkage, popularly speaking three Loop. The molding process is: mold clamping - injection - cooling - mold opening (synchronous mold, storage) - gap time. For example, the molding time of a normal injection molding machine is 10 seconds, and the high-speed injection molding machine uses the principle of three-axis linkage. The molding time is shortened by about 6 seconds, and the two small steps are subtracted, but the time is increased by about half.
The high-speed injection molding machine is environmentally friendly, and the standard pump used in ordinary injection molding machines has a large pollution in terms of electric power, hydraulic oil and noise. The high-speed injection molding machine uses a hybrid type of oil pump and servo motor.
The advantages of the servo hydraulic system are as follows: The implementation of the soft start mold will not affect the power network and avoid voltage and electric radiation pollution. It can effectively prevent the oil temperature from being too high and the temperature drop is good. Greatly reduce the replacement rate of hydraulic oil. Due to the better click and power system gear pump, the servo hydraulic system can greatly reduce the machine operation and production noise, and can better improve the working environment.
