[0021] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present utility model in conjunction with the accompanying drawings of the specification.
[0022] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.
[0024] Embodiment 1
[0025] Referring to Figures 1-5 , which is the first embodiment of the present utility model. This embodiment provides a sealing ring for a die-casting oil cylinder, including a sealing ring main body 100, an extended edge 101, and a support edge 102. The extended edge 101 is integrally formed inside the sealing ring main body 100, and the extended edge 101 is integrally formed outside the sealing ring main body 100. A sealing groove 103 is provided on the side wall of the sealing ring main body 100. A set of sealing grooves 103 is located at the middle position of the extended edge 101, and the outer sealing groove 103 is provided in the middle of the support edge 102.
[0026] Among them, for the sealing ring structure composed of the sealing ring main body 100, the extended edge 101, and the support edge 102, the sealing ring main body 100 is used to connect the extended edge 101 and the support edge 102. The extended edge 101 and the support edge 102 can extend the connecting edge strips on the sealing ring main body 100. When the sealing ring is installed inside the equipment installation groove, the extended edge 101 and the support edge 102 can cooperate with each other to provide more connecting edges, improving the sealing performance of the equipment. Moreover, when the side walls of the extended edge 101 and the support edge 102 undergo flipping movement, the sealing groove 103 can timely discharge the air in the middle, facilitating the alternate contact of the extended edge 101 and the support edge 102 with the side wall of the installation groove and preventing leakage of the equipment.
[0027] Specifically, both the extended edge 101 and the support edge 102 are symmetric structures, and the side walls of the extended edge 101 and the support edge 102 are provided with the same edge strip structure. The edge strips on the side walls of the extended edge 101 and the support edge 102 are parallel and have the same width.
[0028] Among them, the symmetrically arranged extension edges 101 and support edges 102 are connected in a structure that facilitates the adjustment of the sealing ring. When the sealing ring rotates and is misaligned, the extension edges 101 and support edges 102 can replace each other to maintain the sealing of the die-casting equipment.
[0029] Furthermore, the end parts of the sealing grooves 103 extend to the outer side walls of the extension edges 101 and support edges 102 respectively, and the sealing grooves 103 are symmetrically arranged with the sealing ring body 100 as the center.
[0030] Among them, the extension of the sealing grooves 103 to the outer side walls of the extension edges 101 and support edges 102 facilitates the discharge of the air in the middle of the sealing grooves 103, maintains the sealing performance, and enables the extension edges 101 and support edges 102 to contact the side wall of the installation groove conveniently.
[0031] Even further, a core body 104 is filled in the central position of the sealing ring body 100, and the diameter of the core body 104 is not less than the thickness of the sealing ring body 100.
[0032] Among them, the core body 104 is installed in the central position of the sealing ring body 100. The core body 104 can improve the installation strength of the sealing ring, enabling the sealing ring to have better installation strength. When the side wall of the sealing ring body 100 is damaged, the core body 104 can replace the sealing ring body 100 and continue to be clamped in the installation groove to prevent the sealing failure caused by the breakage of the edge of the sealing ring.
[0033] Preferably, the sealing ring body 100, extension edges 101 and support edges 102 are integrally of a square structure, and chamfered edge structures are provided on the end side walls of the extension edges 101 and support edges 102.
[0034] Among them, the overall square structure enables the combined structure of the sealing ring body 100, extension edges 101 and support edges 102 to have more contact edges when being butt-jointed and installed with the installation groove of the die-casting machine. When the sealing ring rotates, it can also maintain multiple sealing fits to keep the sealing performance of the equipment.
[0035] It should be noted that concave points 105 are provided in the middle of the side strips on the side walls of the extension edges 101 and support edges 102, and the concave points 105 are evenly distributed on the side walls of the extension edges 101 and support edges 102.
[0036] Among them, the concave points 105 on the side walls of the extension edges 101 and support edges 102 will contact the inner side wall of the installation groove, squeeze out the air in the middle of the convex points 105 to form a certain negative pressure, fix the sealing ring body 100 in the installation groove, and cooperate with the installation groove to maintain the stability of the position of the sealing ring body 100.
[0037] When in use, the sealing ring is installed in the installation groove of the oil cylinder. The sealing ring and the installation groove are interference fit. The end of the sealing ring extends a certain distance from the inner wall of the equipment. The concave points 105 of the side walls of the extension edge 101 and the supporting edge 102 will contact the inner wall of the installation groove, squeezing out the air between the convex points 105 to form a certain negative pressure, and fixing the sealing ring body 100 in the installation groove. When the oil cylinder body is installed in the middle of the equipment, the side wall of the oil cylinder will contact the extension edge 101 inside the sealing ring body 100, and the extension edge The edge strip of the side wall 101 contacts the side wall of the oil cylinder first to seal the middle of the equipment. Even if the extended edge 101 is misaligned to a certain extent, the sealing groove 103 will be flipped and exposed to discharge the air, and drive the supporting edge 102 on the other side to contact the upper side wall of the installation groove, so that the side wall of the extended edge 101 can be stably sleeved on the outer side wall of the oil cylinder, and cooperate with the supporting edge 102 to maintain the sealing performance of the equipment. The supporting edge 102 on the other side of the sealing ring body 100 will be clamped on the inner side wall of the installation groove to prevent leakage.
[0038] In summary, the present application expands the support connection points of the sealing ring by adding a sealing ring body 101 with a sealing groove 103, and adding mutually cooperating supporting edges 102 and extended edges 101 structures on the sealing ring body 101, and adds a concave point 104 structure on the supporting edge 102 and the extended edge 101. During installation, the air on the side walls of the sealing ring can be squeezed and discharged, so that a certain negative pressure space is formed in the middle of the concave point 104, and the sealing ring is adsorbed in cooperation with the installation groove to maintain the stability of the position of the sealing ring, which is more convenient to use on the oil cylinder and to be installed in conjunction with the oil cylinder.
