Including preformed motor, transmission mechanism and preformed seat；Preformed motor and transmission mechanism are fixed on preformed seat, and preformed motor passes through biography
Motivation structure drives the screw rod in injection barrel to rotate, so as to carry out preformed to the raw material in barrel；Injection mechanism includes injection electricity
Machine and screw nut driving mechanism, injection motor drive preformed seat by screw nut driving mechanism, so that preformed seat promotes
Screw rod is moved ahead and is molded, and barrel component, which is fixed on, to be penetrated on platform foreboard, and is molded motor and is fixed on and penetrate in platform back plate.And barrel
The specific composition and matching relationship of component, preformed mechanism and injection mechanism are varied, but precision be present and have much room for improvement and install
And the troublesome deficiency of maintenance.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of electricity of injection machine for the deficiency of the above-mentioned state of the art
Dynamic injection device, injection precision, convenient installation and maintenance can be improved.
Technical scheme is used by the present invention solves above-mentioned technical problem：
The electric injection device of injection machine, including penetrate pedestal component, preformed mechanism, line slideway, pedestal and injection mechanism；It is described
Penetrating pedestal component includes penetrating platform foreboard, penetrating platform back plate, penetrate platform pull bar, penetrates platform foreboard and penetrates platform back plate corner and is drawn respectively by penetrating platform
Bar connects, and penetrates platform foreboard and penetrates platform back plate bottom respectively by line slideway support and guiding；It is dynamic that the preformed mechanism includes plasticizing
Power apparatus and preformed seat, plasticizing power set are fixed on preformed seat, the drive screw rotation of plasticizing power set, preformed seat bottom
Supported by line slideway and guided, line slideway is placed on pedestal；Injection mechanism includes injection power device and transmission mechanism, note
Penetrate power set and be fixed on and penetrate in platform back plate, injection power device moves the preformed seat by transmission mechanism.
Specifically, above-mentioned plasticizing power set and injection power device are motor, or other can provide power
Equipment.
Above-mentioned transmission mechanism is injection feed screw nut, and so transmission is more steady, accurate.
Dynamometry disk is set between above-mentioned preformed seat and described injection feed screw nut, so can be with accurate feedback injection pressure
And screw back pressure.
Above-mentioned transmission mechanism includes synchronizing wheel, timing belt and injection feed screw nut, a synchronizing wheel and is fixed on motor shaft,
Another synchronizing wheel is fixed on injection leading screw, passes through synchronous band connection between two synchronizing wheels.
For the present invention because four injection pull bar stress are consistent, deflection is also consistent, can guarantee that precision during injection, preformed seat
With penetrate platform foreboard, penetrate platform back plate on the same set of line slideway, preformed seat mobile frictional force is small, and plasticizing precision also carries significantly
It is high.Penetrating platform pull bar when installation and maintenance can dismantle, and facilitate preformed seat to install and repair.
To penetrate platform foreboard due to processing respectively and penetrate platform back plate, difficulty reduces, and part processing precision is higher, while before penetrating platform
Plate, preformed seat and to penetrate platform back plate assembly precision higher.
Because preformed seat barycenter is above injection center line, the sliding block on preformed seat below injection center line,
The power of toppling of preformed seat can be so offset to greatest extent.
Because corner is penetrated with four, platform pull bar intermediate space is bigger, and centre can arrange large-sized belt wheel, can do
To higher gearratio.
