[0041] The bottom end of the injection cylinder 21 is fixedly connected to the top end of the upper mold 12, one end of the pull handle 22 is slidably connected to one side of the outer wall of the injection cylinder 21, one side of the connecting plate 27 is fixedly connected to both ends of the pull handle 22, one side of the rotating gear 24 is rotatably connected to one side of the outer wall of the fixing frame 23, and one end of the connecting rod 25 is threadedly connected to the clamping block 26 through the fixing frame 23;

[0042] The meshing cooperation between the connecting plate 27 and the rotating gear 24 can provide a downward force for the handle 22, and at the same time, the connecting plate 27 and the rotating gear 24 mesh and rotate, so that the clamping block 26 slides and translates along the thread track of the connecting rod 25;

[0043] Working principle: When performing injection molding in the mold;

[0044] First, by pushing the handle 22 upward, the connecting plate 27 can slide upward, thereby engaging and rotating the rotating gear 24, causing the connecting rod 25 to rotate;

[0045] Then, the clamping block 26 on the same central axis is driven to slide along the guide track of the connecting rod 25, so as to assist in clamping the cannula inserted into the injection cylinder 21;

[0046] This step can achieve the effect of assisting injection molding during the injection molding process and prevent leakage during the injection molding process.

The fixed frame 31 is used to rotatably connect to the rotating rod 36 and provide a lifting space for the slider 35. It is fixedly connected to the mounting frame 34 through the slider 35.

[0051] The meshing of the first bevel gear 37 and the second bevel gear 38 can provide a rotational force for the rotating rod 36, so that the slider 35 descends along the thread track of the rotating rod 36, and can drive the first bevel gear 37 to descend stably to remove bubbles;

[0052] Working principle: When automatically removing bubbles from the injection molded surface;

[0053] First, by starting the motor 33, the output shaft of the motor 33 drives the mounting rod 39 to rotate through the coupling, thereby rotating the two sets of first bevel gears 37;

[0054] Next, the first bevel gear 37 drives the second bevel gear 38 to engage and rotate, thereby rotating the rotating rod 36, causing the slider 35 to descend along the threaded track of the rotating rod 36, thereby causing the mounting frame 34 to descend, driving the first bevel gear 37 to descend and remove the bubbles generated;

[0055] This step can automatically remove bubbles from the injection molded surface.
