Description

Technical Field

[0001] This utility model relates to the technical field of sealing rings, specifically to a manufacturing apparatus for rubber sealing rings. Background Technology

[0002] Rubber sealing rings are a commonly used sealing element that fills gaps through the elastic deformation of rubber to prevent fluid (liquid, gas) leakage. They are widely used in machinery, automobiles, aerospace, sanitary ware, pipelines and other fields.

[0003] A search revealed Chinese patent publication number CN217834454U, which discloses a molding device for sealing rings. The device includes a processing table, a molding machine body fixedly mounted on the top of the processing table, a supporting shell at the bottom of the molding machine body, a lower mold fixedly connected to the top of the supporting shell, and an ejection mechanism inside the supporting shell. The ejection mechanism includes a movable crank handle and four movable rods. The movable crank handle is located at one end of the supporting shell, and a rotating shaft is fixedly connected to one side of the movable crank handle. Mold cavities are formed on the four corner surfaces of the top of the lower mold. This invention has a simple and reasonable structure, which facilitates safer removal of the sealing ring by workers, improving the practicality of the molding device. It also makes the ejection arc plate more stable during molding, preventing sealing ring molding failure due to instability of the ejection arc plate. This avoids the problem of existing sealing rings requiring manual removal after heat molding, which may cause burns upon contact and poses a safety hazard, making it unsuitable for practical use.

[0004] However, during the manufacturing of the sealing ring, the sealing ring is heated and formed, causing the sealing ring material to be continuously heated during the melting and solidification stages. As a result, the solidification rate is slow under heating conditions, reducing the production efficiency of the device. Utility Model Content

This device solves the problem that during the manufacturing process of sealing rings, the sealing ring material is continuously heated during the heating and forming process, resulting in a slow solidification rate and reduced production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manufacturing device for rubber sealing rings, comprising a base and a lower mold. A linear motor is fixedly installed at the front end of the base, and a moving plate is fixedly installed at the moving end of the linear motor.

The two heating plates are in contact with the side walls of the upper mold and the lower mold after they are attached to each other, so as to facilitate the heating of the upper mold and the lower mold.

[0009] Preferably, a rear exhaust pipe is fixedly installed inside the rear side wall of the lower mold, and a valve is fixedly installed inside the exhaust pipe. The interior of the exhaust pipe is connected to the interior of the air inlet groove, thereby facilitating the discharge of cold air from inside.

[0010] Preferably, both the air inlet pipe and the branch pipe are flexible hoses, which facilitates the movement of the lower mold.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figure 1-3This utility model provides a manufacturing apparatus for rubber sealing rings, including a base 1 and a lower mold 8. A linear motor 4 is fixedly installed at the front end of the base 1, and a moving plate 5 is fixedly installed at the moving end of the linear motor 4. The lower mold 8 is fixedly installed on the rear side wall of the moving plate 5. An air inlet groove 16 is provided inside the lower mold 8. A cooler 9 is fixedly installed at the upper end of the base 1, and an air inlet pipe 12 is fixedly connected to the air outlet end of the cooler 9. Multiple branch pipes 13 are fixedly installed inside the side wall of the air inlet pipe 12. The ends of the branch pipes 13 all pass through the inside of the right side wall of the lower mold 8 and extend into the inside of the air inlet groove 16. An exhaust pipe 10 is fixedly installed inside the rear side wall. A valve 11 is fixedly installed inside the exhaust pipe 10. The interior of the exhaust pipe 10 is connected to the interior of the air inlet groove 16. Both the air inlet pipe 12 and the branch pipe 13 are flexible hoses. After heating the rubber sealing ring, the moving plate 5 is moved to the outside of the U-shaped heating seat 3 by the linear motor 4. Then, the cold air fan 9 is turned on to input cold air into the interior of the air inlet groove 16, which speeds up the forming rate of the rubber sealing ring. Then, the valve 11 is opened to easily discharge the internal cold air, and the cylinder 6 is closed to move the upper mold 7 upward, making it easy to remove the rubber sealing ring. Example

[0017] To facilitate heating of the upper mold 7 and the lower mold 8, in this embodiment, as follows: Figure 1-3 As shown, a moving groove 14 is provided inside the rear side wall of the moving plate 5. An upper mold 7 is provided at the upper end of the lower mold 8, and a slider 15 is fixedly installed on the front side wall of the upper mold 7. The slider 15 is slidably connected to the inside of the moving groove 14. A cylinder 6 is fixedly installed at the upper end of the moving plate 5. The output shaft of the cylinder 6 is fixedly connected to the upper end of the slider 15 through the inside of the upper side wall of the moving plate 5. The moving plate 5 is located at the rear end of the base 1. A U-shaped heating seat 3 is fixedly installed at the upper end of the base 1. Heating plates 2 are fixedly installed on the upper and lower side walls of the U-shaped heating seat 3 and are located on the left side of the moving plate 5. The two heating plates 2 are bonded to the side walls of the upper mold 7 and the lower mold 8 after they are bonded together. The bottom side wall of the lower mold 8 is bonded to the upper side wall of the heating plate 2 below. When producing the rubber sealing ring, the material of the rubber sealing ring is placed inside the mold cavity. Then the cylinder 6 is opened to move the upper mold 7 downward, so that the upper mold 7 and the lower mold 8 are tightly bonded together. The linear motor 4 is used to move to the left until the upper mold 7 and the lower mold 8 are moved between the two heating plates 2 and the heating plates 2 are opened to heat the upper mold 7 and the lower mold 8.

[0018] It should be noted that, in this embodiment, as Figure 1-3As shown, during the production of rubber sealing rings, the material for the rubber sealing ring is placed inside the mold cavity. Then, cylinder 6 is opened, causing the upper mold 7 to move downwards, tightly fitting the upper mold 7 and the lower mold 8 together. Linear motor 4 is then moved to the left until the fitted upper mold 7 and lower mold 8 are moved between the two heating plates 2, and the heating plates 2 are turned on to heat the upper mold 7 and lower mold 8. After heating the rubber sealing ring, linear motor 4 moves the moving plate 5 to the outside of the U-shaped heating seat 3. Then, the cold air fan 9 is turned on, allowing cold air to be introduced into the air inlet groove 16, accelerating the molding speed of the rubber sealing ring. Then, valve 11 is opened to easily expel the internal cold air, and cylinder 6 is closed, causing the upper mold 7 to move upwards, facilitating the removal of the rubber sealing ring.
