[0020] Therefore, when the injection end 4 moves horizontally under the drive of the driving cylinder or other forms of driving mechanism, the injection end 4 will also drive the guide rod 1 to move accordingly, and the movement distance of the guide rod 1 will be measured in real time by the magnetic scale 2. In conjunction with a computer or other computing tools, technicians can obtain the movement distance data of the injection end 4 and the current position data of the injection end 4 during the movement in real time. The technicians can also control the injection end 4 to stay accurately at a certain predetermined position based on the relevant data and in conjunction with relevant control systems or components to achieve precise injection.

A plurality of threaded holes are also provided on the guide plate 6, and the guide plate 6 is also fixedly installed on the magnesium alloy injection molding machine through bolts or screws.

[0022] Moreover, the guide plate 6 is arranged on one side of the injection end 4, and the guide plate 6 is also parallel to the moving path of the injection end 4; at the same time, a strip hole 7 is also opened on the left side of the guide plate 6, the injection end 4 and the guide rod 1 are respectively located on both sides of the guide plate 6, one end of the intermediate connecting rod 8 is directly fixedly connected to the injection end 4, and the other end is opened with a hinge hole, and the other end of the intermediate connecting rod 8 is sleeved on the left end threaded position of the guide rod 1 through the hinge hole, and a nut is provided at the left end of the guide rod 1 to fix and clamp the intermediate connecting rod 8, so that the guide rod 1 can be connected to the injection end 4 through the intermediate connecting rod 8, and ensure that the injection end 4 can drive the guide rod 1 to move axially through the intermediate connecting rod 8.

Correspondingly, whenever the right end of the guide rod 1 moves to the proximity switch 10 driven by the injection end 4, the proximity switch 10 will send a corresponding control signal to control the injection end 4 to stop moving, so as to further prevent the injection end 4 and the guide rod 1 from moving overtravel, and avoid the guide bearing 9 from colliding with the inner wall of the strip hole 7 to cause structural damage.

[0025] In addition, in this embodiment, the proximity switch 10 is also electrically connected to the control unit of the magnetic scale 2, so that whenever the right end of the guide rod 1 triggers the proximity switch 10 and stops the injection end 4 from moving, the reading of the magnetic scale 2 will also be synchronized to zero to avoid affecting the movement accuracy during the next injection movement.
