The content of the invention
The technical problems to be solved by the invention are that a kind of electric injection dress is provided for the deficiency of the above-mentioned state of the art Put, the power of toppling that preformed seat can be reduced by making it conveniently can be installed and repaired again.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：
The electric injection device of injection machine, including penetrate pedestal component, preformed mechanism and injection mechanism；The pedestal component of penetrating includes Platform foreboard is penetrated, platform back plate is penetrated, penetrates platform base, penetrates platform pull bar and nut, platform foreboard is penetrated, penetrates platform back plate, penetrates platform base and be integral Structure, penetrates platform foreboard, penetrates the end of platform back plate bottom two by penetrating the connection of platform base, penetrate and left a blank in the middle of platform base, penetrate platform base and be in note Penetrate below center line, penetrate platform foreboard and penetrate the end of platform back plate top two respectively by penetrating platform pull bar and nut connection；The pre- molding machine Structure includes plasticizing power set and preformed seat, and plasticizing power set are fixed on preformed seat, the drive screw rotation of plasticizing power set Turn, preformed seat bottom is supported and guided by line slideway, and line slideway, which is placed in, to be penetrated on platform base；Injection mechanism includes injection power Device and transmission mechanism, injection power device, which is fixed on, to be penetrated in platform back plate, and injection power device moves described by transmission mechanism Preformed seat.
Injection center line refers to the center line of injection power device 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, and now, injection center line refers to rolling The axis of ballscrew.
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.
Injection device is when high speed injection, due to penetrating platform front end-plate in injection center line position by power to the left, Penetrating platform front end-plate has a power of toppling counterclockwise, and penetrates platform end plate in injection center line position by power to the right, penetrates platform End plate has the clockwise power of toppling, and this is penetrated platform and is easy for damage like that, and the present invention is penetrating platform foreboard and penetrating platform back plate Symmetrically platform pull bar is penetrated in increase by two on top, threaded one end is fixed, and another end nut is tightened, and is so penetrated and platform front end-plate and is penetrated after platform The top of end plate is penetrated the opposite direction of platform pull bar and tensed, and so penetrates and corresponding pretightning force is left on platform pull bar, and in high speed injection When, penetrate the pretightning force of platform pull bar and can be applied to injection and penetrate toppling for platform front end-plate and power and penetrate the power phase of toppling of platform end plate Mutually offset.
The present invention is due to using penetrating platform foreboard, penetrating the end of platform back plate bottom two by penetrating the connection of platform base, penetrating and being stayed in the middle of platform base Sky, penetrates platform base and is in below injection center line, penetrate platform foreboard and penetrate the end of platform back plate top two respectively by penetrating platform pull bar and spiral shell Mother's connection；The installation site of line slideway also below injection center line, such injection device during the high speed injection on The torque of the inertia force of the preformed motor in face and the frictional force of line slideway can be cancelled out each other, and preformed seat is reduced to greatest extent Topple power.It is additionally, since and penetrates platform base and do not stop preformed seat, installs and penetrate platform pull bar when repairing and can remove, therefore preformed Seat and the part of surrounding are installed and repaired all more convenient.
