Above-mentioned injection driving mechanism provides power by the injection catch bar for injection screw advances, multi-form injection driving mechanism has different realization mechanisms, and when being injection cylinder as the injection driving mechanism, then its injection catch bar is a piston rod.
Above-mentioned injection device is different with the driving mechanism that adopted of injection according to preformed, and the multiple structure of one-tenth capable of being combined can make up as required, as: the injection ball-screw adds servomotor, and preformed is helped DYN dynamic injection device with servomotor is capable of being combined
Add servomotor as the injection ball-screw, the preformed injection device of the electric-hydraulic combined formula of oil motor one-tenth capable of being combined.
Realize the preformed injection device of the electric-hydraulic combined formula of servomotor one-tenth capable of being combined as the injection oil cylinder.
Realize the preformed injection device of oil motor one-tenth full hydraulic capable of being combined as the injection oil cylinder.
Compared with prior art, the invention has the advantages that:
The rotating shaft of preformed mechanism is designed to hollow, the injection rod of injection mechanism and the connection between the injection screw can connect by the hollow part of rotating shaft, the injection motive force of injection mechanism just can be delivered on the injection screw by the hollow of rotating shaft, so structure is more succinct.
In addition, injection process need not drive the motion of whole preformed driving mechanism, from outside watch injection device not have relative motion, be inactive state, so the safety coefficient height; And in injection process, other normal injection device is light relatively for the weight of the moving component of device, and promptly Zhu She movement inertia can be smaller, can improve the response time of injection.
