With the birth of ultra-thin products, ordinary injection molding machines have been unable to meet the injection molding needs of products with thin wall thickness, and the pressure and speed cannot meet the molding requirements, so high-speed injection molding machines have been produced.
In fact, more and more customers will require the purchase of high-speed injection molding machines. Generally speaking, the purpose of purchasing injection molding machines is to shorten the molding cycle, increase the output per unit time, reduce production costs, and improve competitiveness.
Equipped with a high-response servo system, it can provide the corresponding hydraulic oil output flow according to the needs of the action, without overflow loss, and the high-speed injection molding machine can save 30-70% of energy. Equipped with servo motor feed, compared with traditional oil motor, it is more energy-saving and more accurate in positioning (oil motor is optional). The movable template adopts a roller support system to reduce the energy consumption of mold opening and mold closing.
The high-speed injection molding machine is equipped with a computer controller, and the position and temperature control are accurate. Equipped with a servo valve full closed-loop fuel injection system to ensure stable fuel injection (this is a high configuration, and the field machine is generally equipped with a proportional valve).
The oil circuit block is directly mounted on the actuator, making the control more accurate and responsive. Double shooting balance cylinders ensure even force on the shooting table.
The high-speed injection molding machine is environmentally friendly, and the standard pump used by the ordinary injection molding machine pollutes a lot in terms of electricity, hydraulic oil, and noise.
The optimized design of the new locking mechanism makes the locking mechanism move quickly and stably, 10%-20% faster than the previous model. The standard mold is opened and supported at the same time, which greatly saves the molding time (realizes the dual-axis linkage of mold opening and support).
The servo motor is used for feeding, and the molding time is shortened by 40% compared with the traditional machine (the three-axis synchronous movement of feeding, mold opening and mold support can be realized). The movable template adopts a roller support system to improve the efficiency of mold opening and closing. Large aspect ratio, double-line multi-mixing tube group, can fully and quickly melt and plastic.
The whole module independently controls mold clamping, injection molding, feeding, and seating, which will not cause the wrong operation and will not cause personal injury. Hidden mechanical structure, fully enclosed board, high integrity.
To sum up, the high-speed injection molding machine adopts a hybrid type of oil pump and servo motor. The advantages of the servo-hydraulic system are as follows: the soft start of the mold will not affect the power network and avoid voltage and electrical radiation pollution. It can effectively prevent the oil temperature from being too high and cool down well. Greatly reduce the replacement rate of hydraulic oil.
The servo-hydraulic system can greatly reduce the noise of machine operation and production due to its better click and power system gear pump, and can better improve the working environment. The high-speed injection molding machine can save 60~70% of the total power compared with the ordinary injection molding machine, which greatly reduces the cost.
