Driving screw rod 2 ' carries out axial movement A, and hydraulic motor 3 ' is then directly connected to screw rod 2 ' by transmission shaft, therefore screw rod 2 '
Rotary motion B is independent of each other with A is axially moved, non-interference.But by two sides injection cylinder 1 ' when being injected due to screw rod 2 '
Driving, can generate asynchrony phenomenon, and injection power does not act directly on screw rod 2 ', when largely effecting on injection precision and response
Between.
To solve above-mentioned phenomenon, there is another technology to use in the industry at present, as shown in Fig. 2, injection cylinder 1 ' is respectively
It is directly connected to screw rod 2 ' and hydraulic motor 3 '；The program solves the asynchrony phenomenon of above scheme, injection cylinder 1 ' and spiral shell
2 ' coaxial line of bar, injection force can directly act on screw rod 2 ', substantially increase injection precision；But the program is due to screw rod
2 ', injection cylinder 1 ', hydraulic motor 3 ' are located at same axis, can not will be axially moved A and rotary motion B and separate, then inject oil
Cylinder 1 ' will participate in the rotary motion B of screw rod 2 ', increase the sealing part abrasion of injection cylinder 1 ' significantly in this way, be very easy to
Sealing element is caused to damage and oil leak to make component failure influences service life.
Therefore, it is necessary to be further improved.
