Description

Technical Field

[0001] This utility model relates to the field of sealing ring production technology, specifically a mold for sealing ring production. Background Technology

[0002] A sealing ring is an elastic ring-shaped part used to fill gaps at joints to prevent fluid or gas leakage. It is usually made of elastic material, and the choice of material is of great significance to its sealing performance and service life, because the performance of the material directly affects the performance of the sealing ring. In the production of sealing rings, molds are used for forming.

[0003] The existing method of using molds for producing sealing rings involves first adding the raw material for producing the sealing ring into the mold, then extruding and heating the raw material through a heating module. Heating softens the raw material, and then extruding it to shape it, thereby producing the sealing ring.

[0004] However, during the production of the sealing ring, some of the raw material overflows due to heating and extrusion, causing it to stick to the edge of the mold. The only way to remove the sealing ring is to pick it out from the bottom up, which will damage the unformed sealing ring and reduce the pass rate of the finished product. Utility Model Content

[0005] The purpose of this invention is to provide a mold for producing sealing rings, so as to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 5 The mold shown includes a positioning frame 1, a mold body 4 is fitted inside the positioning frame 1, a groove 2 is provided on the outside of the positioning frame 1 near the mold body 4, a slider 3 is slidably connected inside the groove 2, the slider 3 is "L" shaped, one end of the slider 3 near the groove 2 is fixedly connected to the outside of the mold body 4, a spring 5 is fixedly connected inside the groove 2, the end of the spring 5 away from the groove 2 is fixedly connected to one side of the slider 3, the end of the slider 3 away from the groove 2 is rounded, an extrusion block 6 is provided on the outside of the positioning frame 1 away from the slider 3, and a rotating component is provided on the outside of the positioning frame 1.

[0021] Please see Figure 2 The rotating assembly shown in the figure includes a rotating shaft 8, which is fixedly connected to the outside of the positioning frame 1. There are two sets of rotating shafts 8 arranged symmetrically. The end of the rotating shaft 8 away from the positioning frame 1 is rotatably connected to a frame 9, and the pressing block 6 is fixedly connected to the side of the frame 9 near the rotating shaft 8.

[0022] Please see Figure 2 - Figure 5 In the figure, the extrusion block 6 is arranged in a trapezoidal shape, and the frame 9 is fixedly connected to the outside of the motor 10. The output end of the motor 10 is fixedly connected to one of the sets of rotating shafts 8 away from the positioning frame 1.

[0023] Please see Figure 3 - Figure 5 In the diagram, a limiting rod 7 is fixedly connected inside the slide groove 2. The limiting rod 7 is slidably connected inside the slider 3 and is located inside the spring 5.

[0024] Please see Figure 1 - Figure 3 In the figure, the mold body 4 is abutted against the side away from the positioning frame 1 by a heating module 11. The end of the heating module 11 away from the mold body 4 is fixedly connected to a telescopic rod 12. The end of the telescopic rod 12 away from the heating module 11 is fixedly connected to an electrical control module 13.

[0025] Please see Figure 1 - Figure 3 In the diagram, the electronic control module 13 is fixedly connected to the inside of the frame 9 near the top, and the control panel 14 is fixedly connected to the outside of the frame 9 near the motor 10.

[0026] Working principle: First, start the electronic control module 13 through the control panel 14, so that the electronic control module 13 controls the telescopic rod 12 to drive the heating module 11 to rise. At this time, the raw material can be added to one side of the mold body 4. Then, the heating module 11 is heated first. Then, the electronic control module 13 is controlled by the control panel 14 to lower the heating module 11, so that the heating module 11 presses against one side of the mold body 4 containing the raw material. The heating and extrusion of the heating module 11 causes the raw material to be formed on one side of the mold body 4.

[0027] After the heating module 11 and the mold body 4 work together to form the raw material, the control panel 14 can be used to allow the electronic control module 13 to control the telescopic rod 12 to lift the heating module 11, thereby allowing the heating module 11 to detach from one side of the mold body 4. Then, the control panel 14 can be used to start the motor 10, which will drive the rotating shaft 8 to rotate. The rotating shaft 8 will then drive the positioning frame 1 to rotate inside the frame 9 by another set of rotating shafts 8. When the positioning frame 1 rotates, it will drive the slider 3 to rotate together. When the rounded end of the slider 3 contacts the inclined surface of the extrusion block 6, the slider 3 will slide along the inclined surface of the extrusion block 6. At the same time, the slider 3 will also slide inside the slide groove 2, which will drive the mold body 4 to move, thereby allowing the mold body 4 to detach from the positioning frame 1. When the slider 3 slides, it will compress the spring 5, and the mold body 4 will also face downward as the positioning frame 1 rotates. At this time, the sealing ring can be removed from one side of the mold body 4 from top to bottom.

[0028] After the sealing ring is demolded, the control panel 14 is used again to control the motor 10 to rotate in the opposite direction. This allows the motor 10 to drive the rotating shaft 8 and the positioning frame 1 to flip back to their original positions. When the positioning frame 1 rotates in the opposite direction, the slider 3 will disengage from one side of the extrusion block 6. At this time, the spring 5 will push the slider 3 to reset inside the slide groove 2. When the slider 3 resets, the limiting rod 7 restricts the reset position to prevent the slider 3 from shifting. During the extension and retraction process, the spring 5 is also restricted by the limiting rod 7 to prevent the limiting rod 7 from bending inside the slide groove 2 and making it difficult to reset. When the positioning frame 1 is completely flipped back to its original position, the slider 3 is also pushed to its original position by the spring 5. In this way, the mold body 4 will re-enter the positioning frame 1 along with the slider 3, thus continuing the production of the sealing ring.

[0029] It should be noted that this device allows the mold body 4 to face downwards, thereby allowing the mold body 4 to detach from the positioning frame 1, facilitating the downward peeling of the sealing ring attached to the outside of the mold body 4. When the mold body 4 faces upwards, the spring 5 will push the slider 3 inside the slide groove 2, thereby allowing the slider 3 to drive the mold body 4 back into the positioning frame 1, and then continue production, improving the efficiency of production demolding.
