An injection port 5 for injection molding is provided at the top end of the mounting plate 4. The right end of the lower mold 7 is fixedly connected with a fixed block 16. The fixed block 16 is trapezoidal. The fixed block 16 is used to stabilize the position of the lower mold 7 and fix it. The lower mold 7 is slidably connected to the inner wall of the fixed sleeve 8. The bottom end of the inner wall of the housing 1 is fixedly connected with a hydraulic cylinder 14. The output shaft of the hydraulic cylinder 14 is fixedly connected to the bottom end of the connecting frame 15.

[0036] Refer to Figure 2 、 Figure 4 Furthermore, the synchronous adjustment assembly 9 further includes a mounting rod 92 for fixing. The mounting rod 92 is fixedly connected to the rear end of the fixed sleeve 8. The inner wall of the mounting rod 92 is slidably connected with a fixed rod 97. A raised block is provided at the top end of the fixed rod 97 for fitting and fixing with the fixed block 16. The fixed rod 97 and the mounting rod 92 are elastically connected by a first spring 96. The first spring 96 is used for the reset of the fixed rod 97. One end of the first spring 96 is fixedly connected to the bottom end of the fixed rod 97, and the other end of the first spring 96 is fixedly connected to the inner wall of the mounting rod 92.

When the moving rod 98 moves downward, it pulls the rotating rod 93. While the rotating rod 93 rotates along the central axis of the moving rod 98, the rotating rod 93 drives the sliding block 91 to slide, and the sliding block 91 drives the lower mold 7 to slide. When the rotating rod 93 touches the bottom end of the fixed rod 97, the fixed block 16 fixedly connected to the lower mold 7 enters the inner wall of the fixed sleeve 8, and the fixed rod 97 slides down to lock the fixed block 16. At this time, the upper mold 6 and the lower mold 7 are closed. Then, the molten plastic is injected into the mold through the injection port 5. After the plastic is cooled, the above steps are performed in reverse;

[0039] When pushing out the lower mold 7, the stop block 94 can push the sliding block 91 by squeezing the spring 95 to improve the smoothness of the device operation.
