Further technical scheme of the present utility model is: described planetary reduction gear is the right angle planetary reduction gear that includes vertical end and transverse end, described servomotor is vertically fixedly mounted on fixed frame, the output shaft of this servomotor is connected with the vertical end of right angle planetary reduction gear, and the transverse end of right angle planetary reduction gear is connected with one end of shaft coupling through bearing holder component.
Owing to adopting said structure, the screw in injection molding machine electric charging mechanism of the utility model compared with prior art, has following beneficial effect:
1. cost is low:
Because adopting servomotor, the screw in injection molding machine electric charging mechanism of the utility model replaced hydraulic oil motor to drive screw rod, its drive disk assembly is less, and it is shorter, relatively simple for structure that rotary power transmits distance, therefore cost is lower, has higher cost performance.
2. installing space is little:
Because the utility model adopts planetary reduction gear and servomotor combination, screw rod is driven, planetary reduction gear small volume wherein, and there are linear pattern and a perpendicular type, can be according to the different needs of machine, servomotor is mounted to and vertical, level and axially installing, can make compact conformation reasonable, reduce installing space.
3. noise is low:
Because the utility model adopts planetary reduction gear, slow down, because planetary reduction gear itself has smooth running, feature that noise is low, therefore, noise of the present utility model is lower.
4. efficiency is high:
Because adopting servomotor, the utility model replaced hydraulic oil motor to drive screw rod, can in reinforced, carry out die sinking, thimble and locked mode, thereby can shorten about 20-30% circulation timei, greatly improve the operation of a machine efficiency, be easy to apply.
5. applicable on the higher injection machine of precision requirement:
Because planetary reduction gear of the present utility model can adopt micron order planetary reduction gear, on the higher injection machine of precision requirement, and make the control accuracy of injection machine can be to accurate digital control future development.
6. planetary reduction gear is mainly used on automobile, Digit Control Machine Tool, and on injection machine, use this element, be equivalent to automobile, Digit Control Machine Tool mature technology to shift to injection machine aspect, greatly promoted the technology content of injection machine, the skill upgrading of injection machine industry and upgrading have been had to extremely important meaning.
