Abstract
The utility model discloses an energy-saving single-cylinder injection mechanism for a plastic injection machine, which consists of an injection head plate, a dissolving barrel, an injection cylinder and a motor. One end of the injection head plate is connected with the dissolving barrel while the other end is connected with the injection cylinder; the dissolving barrel is internally equipped with a dissolving screw; and one end of a piston in the injection cylinder is connected with the glue-dissolving screw while the other end is connected with the output shaft of the motor by a ball spline shaft. With the adoption of a single-cylinder structure, the mechanism needs one tenth to one fifteenth of the moving parts of a double-cylinder mechanism, thereby reducing the weight of moving parts and the moving inertia. The mechanism adopts a one-line transmission mode and has no redundant transmission part, being conducive to close control. The piston is connected with the output shaft of the motor by the ball spline shaft. The mechanism replaces the traditional rectangular spline shaft transmission part with the ball spline shaft to transform sliding to rolling, thereby reducing the friction and realizing close control and energy saving simultaneously.
Description
Technical field
The utility model relates to a kind of injection machine, particularly a kind of single cylinder injection structure.
Background technology
In suitability for industrialized production, the application of accurate plastic product more and more widely, and is also more and more higher to the requirement of precise injection machine.Traditional twin-tub injection structure can't realize accurate control because heavy moving parts is big, and the inertia of start and stop is also big, does not fit into the production sophisticated product.And piston is connected by the rectangular spline axle with motor in the existing injection machine injection oil cylinder, because in the course of the work, the rectangular spline axle also will axially move when transmitting moment of torsion, so, bigger frictional force is arranged during motion, and the position is difficult for accurately control.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of injection machine energy-saving single cylinder injection structure that can also be energy-conservation when accomplishing accurate control.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of injection machine energy-saving single cylinder injection structure, comprise an injection plate, colloidal sol tube, injection oil cylinder and motor, one end of a described injection plate is connected with the colloidal sol tube, the other end is connected with the injection oil cylinder, in the described colloidal sol tube colloidal sol screw rod is installed, the two ends of described injection oil cylinder are provided with the turnover oilhole, and piston one end connects the colloidal sol screw rod in the described injection oil cylinder, and the other end connects the output shaft of motor by ball spline shaft.
As further improvement of the utility model, the turnover oilhole of close described colloidal sol tube is provided with throttle orifice.
The beneficial effects of the utility model are: the utility model adopts the single cylinder structure, has reduced the weight of moving component, and moving component has only twin-tub to establish the 1/10-1/15 of roping dynamic component, movement inertia is little, adopt one-line transmission, no unnecessary drive disk assembly helps accomplishing tight control.Piston adopts ball spline shaft to replace traditional rectangular spline through-drive part by the output shaft of ball spline shaft connection motor, becomes and slides to rolling, and has reduced frictional force, and having realized can also be energy-conservation when accomplishing precision control.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
