DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Embodiment 1: A mounting groove 23 is provided inside the bottom mold 1, a transmission shaft 13 is installed inside the mounting groove 23, a first gear 17 is installed on the outer sides of both ends of the transmission shaft 13, two second gears 18 are installed inside the mounting groove 23, the second gears 18 are connected to the first gear 17 through tooth meshing, two threaded rods 16 are installed inside the bottom mold 1, the bottom ends of the threaded rods 16 are connected to one end of the second gear 18, a sleeve rod 24 is sleeved on the outer sides of the threaded rods 16, a threaded groove 21 is provided inside the sleeve rod 24, the threaded groove 21 is meshed with the threaded rod 16, the bottom mold 1 A second support rod 14 is installed inside, a slide rod 15 is installed on both sides of the sleeve rod 24, one end of the slide rod 15 is slidably installed inside the outside of the second support rod 14, a limit plate 20 is installed on the top of the sleeve rod 24, and the first half body injection molding groove 3 is installed on the top of the limit plate 20. A limit groove 19 is opened on the top of the bottom mold 1, and a second half body injection molding groove 10 is installed on the top of the bottom mold 1. The second half body injection molding groove 10 is used in conjunction with the first half body injection molding groove 3. A knob 11 is installed on one side of the bottom mold 1, and the output end of the knob 11 extends into the installation groove 23 and is connected with one end of the transmission shaft 13.

[0015] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission shaft 13 and the first gear 17 can be driven to rotate by rotating the knob 11, and the second gear 18 can be driven to rotate by rotating the first gear 17, and the threaded rod 16 can be driven to rotate by rotating the second gear 18. The sleeve rod 24 can be moved up and down along the installation direction of the threaded rod 16 and the second support rod 14 by rotating the threaded rod 16. Since the top of the sleeve rod 24 is installed with the first half injection groove 3 through the limit plate 20, the two ends of the first half injection groove 3 are respectively overlapped with the two ends of the second half injection groove 10 fixed on the top of the bottom mold 1 by descending the sleeve rod 24, so that the first half injection groove 3 The first half body injection molding groove 3 and the second half body injection molding groove 10 form a completed O-shape, and then the rubber sealing ring is injection molded. After the rubber sealing ring is injection molded, the first half body injection molding groove 3 is driven to move upward by rotating the knob 11, so that the two ends of the first half body injection molding groove 3 are separated from the two ends of the second half body injection molding groove 10 to form a height difference, so that the rubber sealing ring after injection molding inside the first half body injection molding groove 3 and the second half body injection molding groove 10 automatically falls off. At this time, the staff only needs to remove the fallen rubber sealing ring, and the rubber sealing ring can be taken out from the first half body injection molding groove 3 and the second half body injection molding groove 10 very conveniently, thereby improving the production efficiency of the rubber sealing ring.

[0016] Embodiment 2: Four foot pads 12 are installed at the bottom of the bottom mold 1, and the four foot pads 12 are respectively located at the four corners of the bottom of the bottom mold 1, a first support rod 4 is installed at the four corners of the top of the bottom mold 1, and a top plate 5 is installed at the top of the first support rod 4, an upper mold 8 is slidably installed on the outer side of the first support rod 4, an integral injection molding groove 7 is installed at the bottom of the upper mold 8, the integral injection molding groove 7 is used in conjunction with the first half injection molding groove 3 and the second half injection molding groove 10, a hydraulic telescopic rod 6 is installed on the top of the top plate 5, the output end of the hydraulic telescopic rod 6 passes through the inside of the top plate 5 and is connected to the top of the upper mold 8, a limiting rod 9 is installed at the bottom of the upper mold 8, a limiting hole 22 is opened at the top of the bottom mold 1, and the limiting hole 22 is used in conjunction with the limiting rod 9.

[0017] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the foot pad 12 installed at the bottom end of the bottom mold 1 can make the entire mold stably placed on the operating table, and the extension of the output end of the hydraulic telescopic rod 6 can drive the upper mold 8 to slide up and down along the installation direction of the first support rod 4, so that the overall injection molding groove 7 coincides with the first half injection molding groove 3 and the second half injection molding groove 10, thereby injecting the rubber sealing ring. After the first half injection molding groove 3, the overall injection molding groove 7 and the second half injection molding groove 10 coincide, the bottom end of the limiting rod 9 will be inserted into the interior of the limiting hole 22, thereby ensuring that the three can completely overlap, thereby improving the quality of the rubber sealing ring injection molding product.

[0018] Working principle: When in use, the extension of the output end of the hydraulic telescopic rod 6 can drive the upper mold 8 to slide up and down along the installation direction of the first support rod 4, so that the overall injection groove 7 coincides with the first half injection groove 3 and the second half injection groove 10, so as to inject the rubber sealing ring. After the rubber sealing ring is injection-molded and cooled, the upper mold 8 is lifted, and the first half injection groove 3 is driven to move upward by rotating the knob 11, so that the two ends of the first half injection groove 3 are separated from the two ends of the second half injection groove 10 to form a height difference, so that the rubber sealing ring after injection molding in the first half injection groove 3 and the second half injection groove 10 automatically falls off. At this time, the staff only needs to remove the fallen rubber sealing ring, and the rubber sealing ring can be easily taken out from the first half injection groove 3 and the second half injection groove 10, thereby improving the production efficiency of the rubber sealing ring.

[0019] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
