[0025] A sealing ring is an annular device used to prevent liquid or gas leakage. It is usually made of elastic material and has a sealing effect. Sealing rings are generally manufactured by injection molding using a sealing ring molding mold. After the sealing ring product is manufactured using the sealing ring molding mold, the sealing ring product is sleeved on its mold core. At this time, the operator needs to manually demold the sealing ring. Specifically, the operator wears heat-insulating gloves and uses the gloves to rub the sealing ring product to remove the sealing ring product from the mold core. The demolding efficiency of the above-mentioned sealing ring demolding method is low and it is difficult to meet the company's efficient production requirements.

[0026] In order to solve the above technical problems, the present invention provides a sealing ring automatic demoulding device and a sealing ring molding equipment.

[0027] See also Figure 1-3In 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 up and down; 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) sleeved on the mold core 110; then the demoulding component 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.

[0028] The technical solution of the present invention first moves the mold core 110 with the sealing ring product to the preset gap 340 between the two groups of demolding components 300 arranged upper and lower; then drives the two groups of demolding components 300 to move closer to each other through the height adjustment mechanism 400, so that the demolding components 300 are connected with the sealing ring product mounted on the mold core 110; then drives the sealing ring product to move toward the free end of the mold core 110 through the demolding component 300 and finally separates from the mold core 110, thereby achieving the purpose of demolding the sealing ring; since the above-mentioned demolding process does not require manual intervention, the demolding efficiency of the sealing ring is greatly improved, so that it meets the high-efficiency production requirements of the enterprise.

[0029] Specifically, the demoulding assembly 300 includes a driving mechanism 310 and a demoulding belt 320 of an annular belt structure, and the demoulding belt 320 is used to fit and contact with the sealing ring product; the driving mechanism 310 is used to drive the demoulding belt 320 to make annular motion, and the annular motion directions of the demoulding belts 320 in the two sets of demoulding assemblies 300 are opposite to each other; through the friction between the demoulding belt 320 and the sealing ring product, the sealing ring product is driven to move toward the free end of the mold core 110 and finally separated from the mold core 110. In this way, the demoulding belt 320 of the annular belt structure is driven by the driving mechanism 310 to make annular motion, and the friction between the demoulding belt 320 and the sealing ring product is used to make the demoulding belt 320 move while driving the sealing ring product to move relative to the mold core 110; and, because the upper and lower sides of the sealing ring product are respectively driven to move by the demoulding 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 the movement, which helps to improve the stability of the sealing ring product when it moves relative to the mold core 110.

[0030] Understandably, as Figure 2As shown, if the free end of the mold core 110 is located at its left end, the demolding belt 320 located on the upper side moves clockwise, and the demolding belt 320 located on the lower side moves counterclockwise, so that the demolding belts 320 on the upper and lower sides combine 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.

[0031] Specifically, each demoulding assembly 300 includes a mounting frame 330, and a driving mechanism 310 and a demoulding belt 320 are mounted on the mounting frame 330; the driving mechanism 310 includes a rotary driving device (not shown in the drawings), a driving roller 311, and a plurality of guide rollers 313; the demoulding belt 320 is arranged in an annular manner between the driving roller 311 and the plurality of guide rollers 313; the rotary driving device is connected to the driving roller 311, and under the driving action of the rotary driving device, the demoulding belt 320 moves in an annular manner around the driving roller 311 and the plurality of guide rollers 313. In this arrangement, the rotary driving device is used as a power source to drive the driving roller 311 to rotate, and the cooperation of the driving roller 311 and the plurality of guide rollers 313 is used to drive the demoulding belt 320 to move in an annular manner around it. Among them, the rotary driving device can select a speed regulating motor, and the speed regulating motor has the characteristics of variable speed and large torque, so as to improve the ease of operation of the demoulding assembly 300.

[0032] Furthermore, the driving mechanism 310 includes a tension adjusting roller 314, and the two axial ends of the tension adjusting roller 314 are lockably slidably connected to the mounting frame 330; the tension adjusting roller 314 is used to adjust the tension of the demoulding belt 320. Such a configuration is made in consideration of the fact that in the process of installing the demoulding belt 320 to the active roller 311 and the plurality of guide rollers 312, there is a gap between the demoulding belt 320 and the active roller 311 and the plurality of guide rollers 312, and the gap will cause the active roller 311 to be unable to effectively drive the demoulding belt 320; based on the above considerations, the present embodiment provides a lockably slidable tension adjusting roller 314 in the driving mechanism 310, and uses the tension adjusting roller 314 to squeeze the demoulding belt 320 to adjust the tension of the demoulding belt 320, so that the demoulding belt 320 can be firmly connected to the active roller 311 and the plurality of guide rollers 312, thereby ensuring that the active roller 311 can effectively drive the demoulding belt 320.

[0033] Furthermore, the surface of the release belt 320 that contacts the sealing ring product has a preset friction coefficient. With such a configuration, since the sealing ring product relies on the friction between the release belt 320 and the sealing ring product to move, the release belt 320 can smoothly drive the sealing ring product to move by increasing the preset friction coefficient of the surface of the release belt 320 that contacts the sealing ring product, thereby ensuring the smooth implementation of the technical solution of the present application. Among them, regarding the method of increasing the preset friction coefficient, an anti-slip texture can be provided on the surface of the release belt 320 or a rubber layer with a higher friction coefficient can be added, etc., which is not specifically limited in the present application.

[0034] As a preferred solution of the above embodiment, the sealing ring automatic demoulding device 200 further includes a fixed bracket 500, which is connected to the sealing ring forming mold 100; and the height adjustment mechanism 400 is installed on the fixed bracket 500. In this configuration, the height adjustment mechanism 400 is installed on the fixed bracket 500, and then connected to the sealing ring forming mold 100 through the fixed bracket 500, so that the sealing ring forming mold 100 and the sealing ring automatic demoulding device 200 are combined to form a whole.

[0035] There are many specific structures of the height adjustment mechanism 400. In this embodiment, the height adjustment mechanism 400 is configured as a double-threaded rod (not shown in the drawings). The two opposite sides of the double-threaded rod respectively have two thread segments with opposite spiral directions. The two thread segments are slidably connected to the demoulding components 300 on the upper and lower sides through thread blocks. With such a configuration, when the double-threaded rod rotates, the two thread blocks respectively move toward or away from each other along the thread segments to which they belong, thereby driving the demoulding components 300 on the upper and lower sides to move toward or away from each other, thereby ensuring the smooth implementation of the technical solution of the present application. The structure is simple and practical.

[0036] It is understandable that those skilled in the art can think of other specific structures of the height adjustment mechanism 400 without creative effort based on their understanding of the technical solution of the present application, and these structures should also fall within the scope of protection of the present application. For example, in a certain embodiment, the height adjustment mechanism 400 includes two groups of cylinder devices (not shown in the drawings), and each group of cylinder devices is arranged in a one-to-one correspondence with each group of demolding components 300; under the coordinated action of the two groups of cylinder devices, the two groups of demolding components 300 move toward or away from each other. In this arrangement, a common cylinder device is used as a driving source, and the two groups of demolding components 300 are synchronously driven by the two groups of cylinder devices to drive the two groups of demolding components 300 to move toward or away from each other at the same time.

[0037] As a preferred solution of the above embodiment, refer to the attached Figure 1The automatic demoulding device 200 for sealing rings further includes a scraper mechanism 600, which is used to cut and peel off the sprue material of the sealing ring product. In this arrangement, it is considered that during the injection molding process of the sealing ring, the side of the sealing ring product will be connected with the sprue material; therefore, the scraper mechanism 600 is provided in this embodiment, and the scraper mechanism 600 is used to cut and peel off the sprue material, so that the sealing ring product after demoulding does not have the sprue material, so as to simplify the production process.

[0038] There are many specific structures of the scraper mechanism 600. In this embodiment, the scraper mechanism 600 includes a scraper member 610 and a mounting seat 620. The mounting seat 620 is mounted on one of the demoulding components 300. The scraper member 610 is mounted on the mounting seat 620. The blade end of the scraper member 610 faces the connection between the sealing ring product and the nozzle material. In this arrangement, since the blade end of the scraper member 610 faces the connection between the sealing ring product and the nozzle material, when the 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 nozzle material, and as the core 110 continues to move, the scraper member 610 cuts and peels off the nozzle material. The structure is simple and practical. In this embodiment, the mounting seat 620 is mounted on the upper demoulding component 300.

[0039] Further, the moving path of the mold core 110 to the preset gap 340 is defined as the first direction, and the blade end of the scraper member 610 is inclined at an acute angle to the first direction. In this way, by setting the blade end of the scraper member 610 at an acute angle to the first direction, the initial contact area between the blade end and the nozzle material is reduced, so that the blade end can more smoothly cut into the connection between the sealing ring product and the nozzle material, thereby improving the success rate of cutting and peeling the nozzle material.

[0040] This embodiment also discloses a sealing ring forming device, Figure 4-5 The sealing ring forming device comprises a sealing ring forming mold 100 and a sealing ring automatic demoulding device 200 of any of the above embodiments. The specific structure of the sealing ring automatic demoulding device 200 can be referred to the above embodiments. Since the sealing ring forming device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0041] In this embodiment, there are two mold cores 110 in the sealing ring molding 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 protection scope of this application.

[0042] Furthermore, the sealing ring molding device also includes a core moving mechanism 700, which is used to drive the core 110 to move to the preset gap 340 of the sealing ring automatic demoulding device 200, so that the sealing ring automatic demoulding device 200 can demould the sealing ring product. In this way, the core moving mechanism 700 is used to move the core 110 after injection molding to the preset gap 340 of the sealing ring automatic demoulding device 200, so that the sealing ring automatic demoulding device 200 can demould the sealing ring product mounted on the core 110.

[0043] Among them, there are many kinds of specific structures about the core moving mechanism 700. In one embodiment, the core moving mechanism 700 includes a movable bracket 710 and a movable slide groove 720. The movable slide groove 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 slidably connected to the movable slide groove 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 groove 720 to the sealing ring automatic demolding device 200, so that the core 110 is located in the preset gap 340.

[0044] 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 arts and will not be described in detail here.

[0045] The above are only optional embodiments of the present invention, and are not intended to 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.
