[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1-3This utility model provides a rubber sealing ring mold that facilitates demolding, including a fixed base plate 1, a movable frame 2 at the top of the fixed base plate 1, and a movable top plate 3 connected to the top of the movable frame 2. A set of fixed seats 11 are fixedly connected to the middle of the top surface of the fixed base plate 1. The top of the fixed seats 11 extends through to the bottom of the movable frame 2 and is connected to a set of lower molds 12. At least two sets of ejector pins 13 are installed on the bottom surface of the movable frame 2 corresponding to the positions of the lower molds 12. Furthermore, the bottom surface of the lower mold 12 has through holes corresponding to the ejector pins 13. The top of the ejector pins 13 can extend to the top surface of the lower mold 12. When the movable frame 2 moves upward, it can drive the ejector pins 13 to move upward and extend to the top surface of the lower mold 12, which facilitates the lifting of the rubber sealing ring in the lower mold 12 and achieves quick demolding.

[0021] Please see Figure 1-2 This utility model provides a rubber sealing ring mold that is easy to demold. A set of covering frames 21 is installed in the middle of the movable frame 2. A set of movable frames 22 is fixedly connected to both the left and right ends of the movable frame 2. A set of movable blocks 23 is slidably connected in both sets of movable frames 22. Two sets of connecting arms 24 are hinged to the front and back of the left and right sets of movable blocks 23. The other ends of the two sets of connecting arms 24 at the same end are respectively connected to the top surface of the fixed base plate 1 and the bottom surface of the movable top plate 3. When the movable top plate 3 moves down, it can drive the connecting arms 24 to rotate, push the movable blocks 23 to the outermost end of the two sets of movable frames 22, and press down the movable frame 2.

[0022] Please see Figure 2 and 4 This utility model provides a rubber sealing ring mold that is easy to demold. The covering frame 21 includes a covering panel 211 and a fixing bolt 212. The covering panel 211 is a right-angle folded plate, and there are two sets. One end of the two sets of covering panels 211 is hinged to each other, and the other end is connected by the fixing bolt 212. The covering frame 21 can wrap around the outside of the upper mold 32 and the lower mold 12 to protect the rubber sealing ring during the extrusion process. The opening of the covering panel 211 can be controlled by rotating the fixing bolt 212 to facilitate the removal of the rubber sealing ring.

[0023] Please see Figure 2-3 This utility model provides a rubber sealing ring mold that is easy to demold. The top surface of the movable top plate 3 is provided with an external component at the middle, which can be connected to the push rod of the external push component.
