[0002] With the continuous development of the high-speed all-electric injection molding machine industry, there are the following problem points in the current plasticizing part: during the high-speed injection process of the injection molding machine, the plasticizing motor has a tendency to swing up and down when starting and stopping injection. At the same time, there is a certain distance between the fixed position of the plasticizing motor and its center of gravity. At this time, a great torque will appear at the connection between the plasticizing motor and the motor mounting plate, which will ultimately lead to the risk of fatigue fracture of the connecting bolts for fixing the plasticizing motor, and at the same time reduce the overall stability of the injection molding machine during the high-speed injection process. There is also the same risk during the transportation of the machine, which needs to be guarded against. Content of the Utility Model

A support rod 6 penetrates through the fixing frame 4 and the guiding frame 5. The fixing frame 4 is provided with a fixing component 7 for fixing the support rod 6. The guiding frame 5 is provided with a guiding and sliding component 8 for guiding the support rod 6. A supporting and connecting component 9 for fixedly connecting with the tail of the plasticizing motor 3 is provided on the outer circumferential wall of the support rod 6. One end of the support rod 6 is fixedly connected to the plasticizing base 1 through the fixing component 7, and the other end is movably connected to the injection platform base 2 through the guiding and sliding component 8. Then, the tail of the plasticizing motor 3 is supported by the supporting and connecting component 9 and fixedly installed on the outer circumferential wall of the support rod 6. During the high-speed injection process of the plasticizing base 1, the tail of the plasticizing motor 3 is supported by the supporting and connecting component 9 and moves along the guiding of the guiding and sliding component 8 along with the support rod 6, thereby improving the stability of the plasticizing motor 3 during the injection process and preventing the connection bolts of the plasticizing motor 3 from breaking due to fatigue.

[0023] Such as Figure 5As shown, specifically, one end of the support rod 6 is provided with a threaded joint 61, and a keyway 62 is opened on one side of the threaded joint 61. A connecting key is installed in the keyway 62. By installing the connecting key into the keyway 62 and engaging it with the guiding groove 73 in the middle of the fixing frame 4, the rotation of the support rod 6 in the middle of the fixing frame 4 is prevented, further improving the stability of the support rod 6 during the sliding process. Finally, the fixing nut 72 is threadedly connected to the threaded joint 61, thereby fixedly connecting one end of the support rod 6 to the plasticizing base 1.

[0024] As Figure 4 shown, specifically, the fixing assembly 7 includes an installation groove 71 provided on one side of the fixing frame 4. A guiding groove 73 is formed by engaging the inner wall of the fixing frame 4 with the connecting groove.

The free end of the support rod 6 is supported and guided by the copper sleeve 82, improving the stability of the support rod 6 during high-speed injection. The lubricating grease added to the guiding and sliding cavity 81 is protected by the oil seals 83 and is not easily leaked from both ends of the guiding frame 5, and can be stored in the guiding and sliding cavity 81 for a long time, making the lubrication of the copper sleeve 82 more sufficient.

Then, lubricating grease is added to the guiding and sliding cavity 81 through the oil nozzle 52, and the gas in the guiding and sliding cavity 81 is discharged through the exhaust hole 51. After the guiding and sliding cavity 81 is filled with lubricating grease, the oil nozzle 52 and the exhaust hole 51 are sealed by the plug heads to prevent the leakage of the lubricating grease. The contact surface between the copper sleeve 82 and the support rod 6 is lubricated by the lubricating grease, thereby reducing the frictional resistance of the linear movement of the support rod 6 and improving the guiding and sliding effect.
