[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] refer to Figures 1-3The illustrated leaf-clamping ring injection molding demolding mechanism includes a moving mold plate, a stationary mold plate, and an ejector plate 1. An upper mold core 2 is fixedly connected inside the moving mold plate, and a lower mold core 3 is fixedly connected inside the stationary mold plate. A slanted guide rod 201 is fixedly connected to the side of the upper mold core 2. During mold parting, the rising of the moving mold plate and the upper mold core 2 causes the slanted guide rod 201 to move upward. A gating channel 301 is provided in the middle of the lower mold core 3, and leaf-clamping forming grooves 302 and clamping ring forming grooves 303 are respectively provided on both sides of the lower mold core 3. The gating channel 301 communicates with the leaf-clamping forming grooves 302 and clamping ring forming grooves 303. An ejector pin and a guide seat are fixedly connected to the ejector plate 1. 4. The ejector pin is used to eject the formed snap leaf and retaining ring. The guide seat 4 is slidably connected to the inclined pin 401. The lower mold core 3 is provided with an inclined groove. The upper end of the inclined pin 401 is provided with a retaining ring forming protrusion. The central angle of the arc surface on the retaining ring forming protrusion is less than 180°. The retaining ring forming protrusion is provided with a forming groove. The forming groove is used to participate in the forming of the protrusion part on the retaining ring. The upper end of the inclined pin 401 is slidably connected to the inclined groove. The lower end of the inclined pin 401 is slidably connected to the guide seat 4. The side slider 5 is slidably connected to the side of the lower mold core 3. The side insert rod 501 is fixedly connected to the side slider 5. The side insert rod 501 participates in the forming of the snap leaf 6.

[0017] The side slider 5 has an oblique insertion hole, and the oblique guide rod 201 is slidably connected to the oblique insertion hole. The lifting and lowering of the oblique guide rod 201 can drive the side slider 5 to perform a lateral core pulling action.

[0018] Both the upper mold core 2 and the lower mold core 3 have positioning grooves, and both the upper mold core 2 and the lower mold core 3 have positioning protrusions corresponding to the positioning grooves.

[0019] The guide seat 4 has a T-shaped groove. The guide seat 4 is used to guide and limit the sliding of the inclined pin 401. The cross-section of the lower end of the inclined pin 401 is T-shaped.

[0020] The lower mold core 3 has through holes corresponding to the side insert rods 501, and the side insert rods 501 are slidably connected to the lower mold core 3.

[0021] The working principle of this utility model is as follows: After the retaining ring 7 and the snap-on leaf 6 are completed, the moving template and the upper mold core 2 are raised to perform the mold separation action. First, under the action of the inclined guide rod 201, the side insert rod 501 and the side slider 5 slide away from the lower mold core 3 to perform lateral core pulling. Then, the ejector plate 1 is driven to rise. At the snap-on leaf forming groove 302, the snap-on leaf is ejected from the snap-on leaf forming groove 302 by the ejector pin on the ejector plate. At the retaining ring forming groove 303, the inclined pin 401 will eject the retaining ring 7 from the retaining ring forming groove 303 (the notch of the retaining ring 7 can partially deform when it contacts the lower mold core 3 during demolding). Then, the retaining ring 7 can be removed from the forming groove (the central angle of the arc surface participating in the forming on the retaining ring forming protrusion is less than 180°, ensuring that the retaining ring 7 can be smoothly removed from the retaining ring forming protrusion).

[0022] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
