Abstract

The invention discloses an injection shaft support connecting device which solves the technical problems of non-firm and non-reliable structure, short service life and the like of the prior art. The injection shaft support connecting device comprises an injection platform which is provided with an inner cavity, a bearing base is inserted in the inner cavity and is fixedly connected with the injection platform, an injection shaft, which is connected with the bearing base in a rolling manner, is arranged in the bearing base, and is provided with an injection shaft center hole, an injection belt wheel is fixedly connected to one end of the injection shaft, the other end of the injection shaft is fixedly connected with a ball screw after passing through the injection shaft center hole, the ball screw is connected with an injection thrust frame, and a ball nut is arranged on the ball screw in a sleeved manner, and is fixedly connected with the injection thrust frame. The injection shaft support connecting device provided by the invention is capable of ensuring that an injection machine realizes an injection function, and enables the injection machine to have firm and stable properties for a long time.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and relates to an injection molding machine, in particular to an injection shaft supporting connection device. Background technique [0002] In the injection stage of the working process, the injection screw needs to move forward and backward along the axis. When pushing forward, the screw does not rotate, and a huge forward thrust needs to be applied to the screw. This linear movement and force are transmitted through the injection shaft, and the injection shaft will be subjected to torque and radial force at the same time during the working process. The plasticizing parts of the injection molding machine driven by the servo motor need to convert the rotary motion into a linear motion. High-quality injection molding machines also require flexible rotation of the injection shaft, stable and firm support, and high transmission efficiency. [0003] The supporting connection of the injec...
