Problems solved by technology

In the current traditional injection molding device, there are many and complicated parts that need to move during the injection process (for example, including screws, servo motors, pre-molded transmission systems, bearing sets, injection nuts, and injection skateboard seats, etc.)
According to Newton's second law, when the injection pressure is constant, if the total mass of the injection motion system is large, the acceleration obtained by the screw will decrease accordingly, that is, the injection response speed will be gre

Abstract

The invention provides a high-performance electric injection molding mechanism and an injection molding machine. The injection molding mechanism comprises a screw, a screw driving shaft, a ball screwand an axial guiding mechanism, wherein the screw driving shaft comprises a ball spline and a ball nut. When the injection molding mechanism and the injection molding machine provided by the inventionperform injection action, only a small number of parts, including the screw, the screw driving shaft and the like, need to move, and the other driving and transmission parts do not move axially withthe injection action; and the mechanism has light weight during injection movement, so movement inertia is greatly reduced, and thus, the response speed and accuracy of the injection action are greatly improved, and driving power is also greatly reduced.

Description

technical field [0001] The invention belongs to the field of plastics, and relates to an electric injection molding mechanism used in injection molding machines and the like. Background technique [0002] The consumption rate of the plastics industry has been increasing, therefore, the improvement of the overall technical level of injection molding machines is very important to enhance the competitiveness of the plastics industry. [0003] At present, the injection molding machine mainly includes motors, reduction transmission systems, screws, screw nuts and other components. Among them, the screw is an important part of the injection molding machine, which is used to transport, compact, melt, stir and apply pressure to plastics. All of the above The action is accomplished by the rotation of the screw in the barrel and the movement along the axial direction. When the screw rotates, the plastic will generate friction and mutual motion against the inner wall of the barrel, th...
