[0028] A vaginal electrode injection mold with good pressing effect, such as Figures 1 to 3 As shown, it includes a lower mold 1 and an upper mold 2 that fit each other, and a pressure control component 3 is provided at one end of the lower mold 1 and the upper mold 2 that contact each other. The pressure control component 3 is the same as the component structure of the connecting groove and the connecting block and the magnetic switch controller in the patent with Chinese Patent Publication No. CN111186092A. The lower mold 1 and the upper mold 2 are both provided with a mold cavity 5 on one side opposite to each other, and the top of the upper mold 2 is provided with an injection hole 4. The upper mold 2 is provided with an injection flow channel connecting the mold cavity 5 and the injection hole 4. The bottom end of the mold cavity 5 in the lower mold 1 is provided with a cavity 6, and the bottom end of the lower mold 1 is provided with a accommodating cavity 7. The bottom end of the mold cavity 5 located in the lower mold 1 is provided with a push block 8. The top of the push block 8 is a curved surface that fits the inner wall of the bottom end of the mold cavity 5. A push rod 9 is fixed to the bottom end of the push block 8. The push rod 9 passes through the cavity 6 and is connected to a conical block 10. The outer wall of the push rod 9 slides with the lower mold 1. A return spring 11 is sleeved on the outer wall of the push rod 9. The two ends of the return spring 11 are respectively connected to the inner wall of the top end of the accommodating cavity 7 and the outer wall of the top end of the conical block 10. A movable plate 12 is slidably connected to the bottom end of the accommodating cavity 7. A fixed rod 13 is fixed to the end of the top of the movable plate 12 away from the conical block 10. An avoidance groove 14 is opened on the outer wall of one side of the lower mold 1. A pull rod 15 is slidably connected to the inner wall of the avoidance groove 14, and one end of the pull rod 15 is connected to the movable plate 12.

[0029] During production, injection is performed into the mold cavity 5 through the injection hole 4. When the vaginal electrode molded inside the mold cavity 5 is cooled to a certain degree, the lower mold 1 and the upper mold 2 are separated, and the pull rod 15 is pulled to one side to drive the movable plate 12 to move. When the fixed rod 13 contacts the conical block 10, since the conical block 10 is conical, the conical block 10 is squeezed by the fixed rod 13 and pushes the push block 8 upward. The reset spring 11 is compressed to push the vaginal electrode out of the mold cavity 5, and then the pull rod 15 is reset, and the push block 8 is reset under the action of the reset spring 11.

[0030] By setting a push block 8, a push rod 9, a conical block 10, a reset spring 11, a movable plate 12 and a fixed rod 13, the pull rod 15 is pulled to drive the movable plate 12 to move. When the fixed rod 13 contacts the conical block 10, due to the conical shape of the conical block 10, the conical block 10 is squeezed by the fixed rod 13 and pushes the push block 8 upward. The reset spring 11 is compressed to push the vaginal electrode out of the mold cavity 5, so that the vaginal electrode is easily removed.

[0031] Example 2

[0032] A vaginal electrode injection mold with good pressing effect. This embodiment makes the following improvements on the basis of embodiment 1: Figures 2 to 4 As shown, a connecting frame 16 is fixed to the outer wall of the top end of the movable plate 12, and the connecting frame 16 is located on the side of the fixing rod 13 close to the conical block 10, and a fixing frame 18 is fixed to the outer wall of the top end of the accommodating cavity 7, and both ends of the fixing frame 18 are slidably connected with knocking rods 19, and the knocking rod 19 is L-shaped, and the top end of the knocking rod 19 contacts and cooperates with the outer wall of the bottom end of the mold cavity 5, and the outer wall of the knocking rod 19 is sleeved with a reset spring 20, and the two ends of the reset spring 20 are respectively connected to the knocking rod 19 and the fixing frame 18, and a plurality of protrusions 17 are fixed to the inner wall of the top end of the connecting frame 16, and the protrusions 17 are conical, and the plurality of protrusions 17 are arranged equidistantly in a straight line and increase one by one along the conical block 10 toward the fixing rod 13, and the outer wall of the knocking rod 19 contacts and cooperates with the outer wall of the protrusions 17.

[0033] When the movable plate 12 moves to one side, the connecting frame 16 moves with the movable plate 12. When the protrusion 17 pushes the knocking rod 19 to move downward, when the knocking rod 19 passes over a protrusion 17, the reset spring 20 drives the knocking rod 19 to reset, and the mold cavity 5 is knocked to demold, so as to avoid the vaginal electrode and the mold cavity 5 from sticking when the push block 8 is pushed. Since the protrusions 17 are enlarged one by one, the force of knocking on the mold cavity 5 is gradually increased, so that the demolding effect is better.

[0034] By providing a connecting frame 16, a protrusion 17, a fixing frame 18, a knocking rod 19 and a reset spring 20, when the movable plate 12 moves to one side, the connecting frame 16 moves with the movable plate 12, and when the protrusion 17 pushes the knocking rod 19 to move downward, when the knocking rod 19 passes over a protrusion 17, the reset spring 20 drives the knocking rod 19 to reset, and knocks the mold cavity 5 to demold it, so as to avoid the vaginal electrode and the mold cavity 5 from sticking when the push block 8 is pushed.

[0035] By fixing the connecting frame 16 to the outer wall of the top end of the movable plate 12 and pulling the pull rod 15, the vaginal electrode can be knocked out of the mold and pushed out, which is easy to operate.

[0036] Working principle: During production, injection is performed into the mold cavity 5 through the injection hole 4. When the vaginal electrode molded in the mold cavity 5 cools to a certain degree, the lower mold 1 and the upper mold 2 are separated, and the pull rod 15 is pulled to one side to drive the movable plate 12 to move. The connecting frame 16 moves with the movable plate 12. When the bump 17 pushes the knocking rod 19 to move downward, when the knocking rod 19 passes over a bump 17, the reset spring 20 drives the knocking rod 19 to reset, and the mold cavity 5 is knocked to demould, avoiding When the push-free block 8 is pushed, the vaginal electrode adheres to the mold cavity 5. As the protrusions 17 increase one by one, the force of knocking on the mold cavity 5 also gradually increases, making the demoulding effect better. When the fixed rod 13 contacts the conical block 10, since the conical block 10 is conical, the conical block 10 is squeezed by the fixed rod 13, pushing the push block 8 upward, and the reset spring 11 is compressed to push the vaginal electrode out of the mold cavity 5, and then the pull rod 15 is reset, and the push block 8 is reset under the action of the reset spring 11.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
