[0034] A sealing ring is an annular device used to prevent the leakage of liquids or gases. It is typically made of an elastic material and provides a sealing effect. Sealing rings are typically manufactured by injection molding using a sealing ring mold. After the sealing ring product is produced using the sealing ring mold, it is placed around the mold core. At this point, the operator must manually remove the sealing ring from the mold. Specifically, the operator wears heat-insulating gloves and rubs the sealing ring product with the gloves to remove it from the mold core. This sealing ring demolding method has low demolding efficiency and is difficult to meet the company's high-efficiency production requirements.

[0035] In order to solve the above technical problems, the utility model provides an automatic demoulding device for a sealing ring and a sealing ring forming device.

[0036] See also Figure 1-3 In one embodiment of the present invention, the automatic demoulding device 200 for sealing rings is applied to a sealing ring forming mold 100, wherein the sealing ring forming mold 100 includes a mold core 110; specifically, the automatic demoulding device 200 for sealing rings includes two groups of demoulding components 300 and a height adjustment mechanism 400 arranged upper and lower; a preset gap 340 for the mold core 110 to move is provided between the two groups of demoulding components 300; the height adjustment mechanism 400 connects the two groups of demoulding components 300; when the mold core 110 moves to the preset gap 340, the height adjustment mechanism 400 drives the two groups of demoulding components 300 to move closer to each other, so that the demoulding components 300 are connected to the sealing ring product (not shown in the drawings) mounted on the mold core 110; then the demoulding components 300 can drive the sealing ring product to move toward the free end of the mold core 110 and finally separate from the mold core 110.

[0037] The technical solution of the present invention first moves the mold core 110 with the sealing ring product mounted thereon to the preset gap 340 between the two sets of demoulding components 300 arranged above and below; then, the height adjustment mechanism 400 drives the two sets of demoulding components 300 to move closer to each other, so that the demoulding components 300 are connected to the sealing ring product mounted on the mold core 110; then, the demoulding component 300 drives the sealing ring product to move toward the free end of the mold core 110 and finally separates from the mold core 110, thereby achieving the purpose of demoulding the sealing ring; since the above-mentioned demoulding process does not require manual intervention, the demoulding efficiency of the sealing ring is greatly improved, so that it meets the high-efficiency production requirements of the enterprise.

[0038] Specifically, the demolding assembly 300 includes a drive mechanism 310 and an annular stripping belt 320. The stripping belt 320 is configured to contact the sealing ring product. The drive mechanism 310 is configured to drive the stripping belt 320 to perform annular motion, with the annular motion directions of the stripping belts 320 in the two demolding assemblies 300 being opposite to each other. The friction between the stripping belt 320 and the sealing ring product drives the sealing ring product toward the free end of the mold core 110 and ultimately away from the mold core 110. With this arrangement, the drive mechanism 310 drives the annular stripping belt 320 to perform annular motion. The friction between the stripping belt 320 and the sealing ring product causes the stripping belt 320 to move, thereby simultaneously causing the sealing ring product to move relative to the mold core 110. Furthermore, because the upper and lower sides of the sealing ring product are driven to move by the stripping belts 320 located on the upper and lower sides, the forces on the upper and lower sides of the sealing ring product are balanced during movement, thereby improving the stability of the sealing ring product as it moves relative to the mold core 110.

[0039] Understandably, as Figure 2 As shown, if the free end of the mold core 110 is located at its left end, the demoulding belt 320 located on the upper side moves clockwise, and the demoulding belt 320 located on the lower side moves counterclockwise, so that the demoulding belts 320 on the upper and lower sides are combined to drive the sealing ring product to move toward the left end of the mold core 110, so as to achieve the purpose of separating the sealing ring product from the mold core 110.

[0040] Specifically, each demolding assembly 300 includes a mounting frame 330, to which a drive mechanism 310 and a demolding belt 320 are mounted. The drive mechanism 310 includes a rotary drive device (not shown), a driving roller 311, and a plurality of guide rollers 313. The demolding belt 320 is annularly arranged between the driving roller 311 and the plurality of guide rollers 313. The rotary drive device is connected to the driving roller 311, and driven by the rotary drive device, the demolding belt 320 moves in an annular motion around the driving roller 311 and the plurality of guide rollers 313. This arrangement uses the rotary drive device as the power source to rotate the driving roller 311, and the cooperation between the driving roller 311 and the plurality of guide rollers 313 drives the demolding belt 320 in an annular motion around it. The rotary drive device can be a speed-controlled motor, which utilizes its variable speed and high torque to enhance the ease of operation of the demolding assembly 300.

[0041] Furthermore, the drive mechanism 310 includes a tension-adjusting roller 314, whose axial ends are lockably and slidably connected to the mounting bracket 330. The tension-adjusting roller 314 is used to adjust the tension of the release belt 320. This arrangement takes into account that during the process of mounting the release belt 320 to the active roller 311 and the guide rollers 312, a gap may remain between the release belt 320 and the active roller 311 and the guide rollers 312. This gap may prevent the active roller 311 from effectively driving the release belt 320. Based on this consideration, the present embodiment provides a lockable and slidable tension-adjusting roller 314 in the drive mechanism 310. The tension-adjusting roller 314 is used to squeeze the release belt 320 to adjust the tension of the release belt 320, ensuring that the release belt 320 is securely connected to the active roller 311 and the guide rollers 312, thereby ensuring that the active roller 311 can effectively drive the release belt 320.

[0042] Furthermore, the surface of the release strip 320 that contacts the sealing ring product has a preset friction coefficient. With this configuration, since the sealing ring product relies on friction between it and the release strip 320 for movement, increasing the preset friction coefficient of the surface of the release strip 320 that contacts the sealing ring product ensures that the release strip 320 can smoothly move the sealing ring product, thereby ensuring the smooth implementation of the technical solution of this application. Regarding methods for increasing the preset friction coefficient, the release strip 320 can be provided with an anti-slip texture or a rubber layer with a higher friction coefficient, etc., which are not specifically limited in this application.

[0043] As a preferred embodiment of the above embodiment, the automatic sealing ring demolding device 200 further includes a fixed bracket 500 connected to the sealing ring forming mold 100; and a height adjustment mechanism 400 is mounted on the fixed bracket 500. With this arrangement, the height adjustment mechanism 400 is mounted on the fixed bracket 500 and then connected to the sealing ring forming mold 100 via the fixed bracket 500, so that the sealing ring forming mold 100 and the automatic sealing ring demolding device 200 are combined to form a whole.

[0044] There are many different specific configurations for the height adjustment mechanism 400. In this embodiment, the height adjustment mechanism 400 is configured as a double-threaded rod (not shown in the accompanying drawings). Opposite sides of the double-threaded rod have two threaded segments with opposite spiral directions. These two threaded segments are slidably connected to the upper and lower demolding assemblies 300 via threaded blocks. With this configuration, when the double-threaded rod rotates, the two threaded blocks move toward or away from each other along their respective threaded segments, thereby driving the upper and lower demolding assemblies 300 to move toward or away from each other. This ensures the smooth implementation of the technical solution of this application, resulting in a simple structure and strong practicality.

[0045] It is understandable that those skilled in the art, based on their understanding of the technical solutions of this application, can, without inventive effort, conceive of other specific structures of the height adjustment mechanism 400, which should also fall within the scope of protection of this application. For example, in one embodiment, the height adjustment mechanism 400 includes two sets of cylinder devices (not shown in the accompanying drawings), each set of cylinder devices corresponding to each set of demolding assemblies 300. Under the coordinated action of the two sets of cylinder devices, the two sets of demolding assemblies 300 move toward or away from each other. In this arrangement, a common cylinder device is used as the driving source, and the two sets of cylinder devices are used to synchronously drive the two sets of demolding assemblies 300, thereby causing the two sets of demolding assemblies 300 to move toward or away from each other simultaneously.

[0046] As a preferred solution of the above embodiment, refer to the attached Figure 1 The automatic sealing ring demolding device 200 also includes a scraper mechanism 600, which is used to remove and peel off the sprue material of the sealing ring product. This configuration takes into account that during the sealing ring injection molding process, sprue material may be attached to the side of the sealing ring product. Therefore, this embodiment includes a scraper mechanism 600 to remove and peel off this sprue material, eliminating the sprue material from the sealing ring product after demolding, thereby simplifying the production process.

[0047] There are many different specific structures for the scraper mechanism 600. In this embodiment, the scraper mechanism 600 includes a scraper member 610 and a mounting base 620. The mounting base 620 is mounted on one of the demolding assemblies 300. The scraper member 610 is mounted on the mounting base 620, with the blade end of the scraper member 610 facing the connection between the sealing ring product and the sprue material. With this arrangement, since the blade end of the scraper member 610 faces the connection between the sealing ring product and the sprue material, when the mold core 110 moves to the preset gap 340, the blade end of the scraper member 610 contacts the connection between the sealing ring product and the sprue material. As the mold core 110 continues to move, the scraper member 610 removes and peels the sprue material. This simple structure is highly practical. In this embodiment, the mounting base 620 is mounted on the upper demolding assembly 300.

[0048] Furthermore, the movement path of the mold core 110 to the preset gap 340 is defined as a first direction, and the blade end of the scraper 610 is tilted at an acute angle to the first direction. This arrangement reduces the initial contact area between the blade end of the scraper 610 and the sprue material, allowing the blade end to more smoothly penetrate the connection between the sealing ring product and the sprue material, thereby improving the success rate of removing and peeling the sprue material.

[0049] This embodiment also discloses a sealing ring forming device, see the attached Figure 4-5The sealing ring forming apparatus includes a sealing ring forming mold 100 and an automatic sealing ring demolding device 200 according to any of the above-described embodiments. The specific structure of the automatic sealing ring demolding device 200 can be found in the above-described embodiments. Since the sealing ring forming apparatus utilizes all of the technical solutions of all of the above-described embodiments, it possesses at least all of the beneficial effects brought about by the technical solutions of the above-described embodiments, and therefore will not be further elaborated upon here.

[0050] In this embodiment, there are two mold cores 110 in the sealing ring forming mold 100, and the two mold cores 110 are arranged parallel to each other; it can be understood that in other embodiments, setting the number of mold cores 110 to three or more should also fall within the scope of protection of this application.

[0051] Furthermore, the sealing ring molding apparatus also includes a core moving mechanism 700, which is used to drive the core mold 110 to move to the preset gap 340 of the automatic sealing ring demolding device 200, so that the automatic sealing ring demolding device 200 can demold the sealing ring product. In this arrangement, the core moving mechanism 700 is used to move the core mold 110 after injection molding into the preset gap 340 of the automatic sealing ring demolding device 200, so that the automatic sealing ring demolding device 200 can demold the sealing ring product mounted on the core mold 110.

[0052] Among them, there are many specific structures of the core moving mechanism 700. In one embodiment, the core moving mechanism 700 includes a movable bracket 710 and a movable slide 720. The movable slide 720 is horizontally arranged on the side of the sealing ring molding mold 100 and the sealing ring automatic demolding device 200. One end of the movable bracket 710 is slidingly connected to the movable slide 720, and the other end of the movable bracket 710 is fixedly connected to the core 110; when the core 110 is located in the sealing ring molding mold 100 and the injection molding is completed, the movable bracket 710 slides along the movable slide 720 to the sealing ring automatic demolding device 200 so that the core 110 is located in the preset gap 340.

[0053] It should be noted that the other contents of the automatic demoulding device for sealing rings and the sealing ring forming equipment disclosed in the present invention are prior art and will not be described in detail here.

[0054] The above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. Any direct / indirect application of the present invention in other related technical fields is included in the patent protection scope of the present invention.
