[0013] Beneficial effects:

[0014] 1. In the working state, the movable plate under the table will be exerted with a force toward the injection plate, causing the movable plate to move toward the injection plate and drive the sliding hole to slide on the surface of the sliding rod, while compressing the reset spring.

[0016] 3. Before injection molding the sealing ring, the staff will first replace different splicing molds and splicing molds according to the size of the injection molding sealing ring. The staff only needs to apply an upward force to the splicing mold and the splicing mold to pull the splicing mold and the splicing mold out from between the two positioning plates and replace them with new splicing molds, which increases the applicability of the injection molding rubber ring.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a sealing ring rubber injection molding machine includes an injection molding plate 1, a movable plate 2 is slidingly provided on one side of the injection molding plate 1, a splicing mold 3 is detachably provided on the side of the injection molding plate 1 close to the movable plate 2, a splicing mold 4 is detachably provided on the side of the movable plate 2 close to the injection molding plate 1, a plurality of injection holes 5 are opened on one side of the injection molding plate 1, sliding rods 6 are respectively fixed at the four corners of the injection molding plate 1 close to the movable plate 2, sliding holes 7 are respectively opened at the four corners of the side of the movable plate 2, the sliding holes 7 and the sliding rods 6 are slidably inserted, and a return spring 8 is surrounded by the surface of the sliding rod 6, one end of the return spring 8 is fixed to one side of the injection molding plate 1, and the other end of the return spring 8 is fixed to one side of the movable plate 2, a fixed plate 9 is provided on one side of the movable plate 2, and a cylinder 10 is fixed on one side of the fixed plate 9, and one end of the telescopic rod of the cylinder 10 passes through the fixed plate 9 and is fixed to one side of the movable plate 2.

[0024] During use, in the working state, the movable plate 2 under the table will be exerted with a force toward the injection molding plate 1, so that the movable plate 2 moves toward the injection molding plate 1, and drives the sliding hole 7 to slide on the surface of the sliding rod 6, while compressing the reset spring 8. At this time, the splicing mold 3 and the splicing mold 4 overlap together, and then the gap between the splicing mold 3 and the splicing mold 4 is injection molded through the injection hole 5. After the injection is completed and solidified, the cylinder 10 stops working, so that the reset spring 8 loses the force of being squeezed. The reset spring 8 returns to its original state and can quickly push the movable plate 2 back to its original position, increasing the frequency of the injection molding sealing ring.

[0025] like Figure 2 and Figure 3 As shown, a water tank 13 is fixed to the top surface of the injection molding plate 1, and two fixing holes 14 are provided on one side of the water tank 13.

The low-temperature water in the cooling water pipe 15 absorbs the heat of the rubber material in the mold, thereby accelerating the solidification speed of the sealing ring.

[0027] like Figure 2 and Figure 4 As shown, two positioning plates 17 are fixed on both sides of the injection molding plate 1 and the movable plate 2 where they are close to each other, wherein the two positioning plates 17 form a group, and the two groups of positioning plates 17 are respectively slidably arranged with the splicing mold 3 and the splicing mold 4, and support plates 20 are fixed on both sides of the injection molding plate 1 and the movable plate 2 where they are close to each other, and limiting grooves 19 are respectively provided on both sides of the splicing mold 3 and the splicing mold 4, and a limiting plate 18 is fixed on one side of the positioning plate 17, and the limiting plate 18 and the limiting groove 19 are slidably inserted.

[0028] During use, before injecting the sealing ring, the staff will first replace different splicing molds 4 and splicing molds 3 according to the size of the injection-molded sealing ring. The staff only needs to apply an upward force to the splicing mold 3 and the splicing mold 4 to pull the splicing mold 3 and the splicing mold 4 out from between the two positioning plates 17, and replace them with new splicing molds 3 and splicing molds 4, thereby increasing the applicability of the injection-molded rubber ring.
