Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0044] Please refer to Figures 1 to 6 , and now the vulcanization mold for producing sealing rings provided by the present application will be described. The vulcanization mold for producing sealing rings includes a mold body 1, a plurality of ring cutting components 4, and a jacking component 5.

[0045] In the prior art, after the sealing ring raw material is vulcanized, there will be waste edges extending radially outward along the outer peripheral wall of the sealing ring finished product. The waste edges are formed by the excess raw material being extruded out of the mold during vulcanization; currently, after the sealing ring is vulcanized, it needs to be manually taken out and the waste edges are torn off, and this process is inefficient.

[0046] The mold body 1 is made of high-temperature resistant and corrosion-resistant materials; the mold body 1 is used to be installed on a vulcanizer and can be fixed on the vulcanizer through a fixture or a fastening bolt; the upper side surface of the mold body 1 has a plurality of lower forming grooves 11 for the partial embedding of the sealing ring; the lower forming grooves 11 are annular, and a plurality of lower forming grooves 11 are coaxially arranged; a cover plate 2 is also hinged on the mold body 1 in the horizontal direction, and the cover plate 2 has a plurality of upper forming grooves 21 adapted to communicate with the plurality of lower forming grooves 11 one by one; wherein, at the notch of each upper forming groove 21 and the lower forming groove 11, there is a waste groove 3 extending outward for the waste edge to be embedded.

[0047] By adopting the above technical solution, the mold body 1 can be adapted to vulcanize sealing rings of various model specifications, avoiding the cumbersome work of replacing the entire vulcanization mold due to changing the production specifications of the sealing ring, and improving the applicability of the mold body 1.

[0048] A plurality of ring cutting components 4 are all arranged on the cover plate 2. The plurality of ring cutting components 4 correspond to the plurality of upper forming grooves 21 one by one, and are used to be inserted into the corresponding two waste grooves 3.

[0049] The jacking assembly 5 is arranged on the mold body 1 and is used to drive the sealing ring to move upward relative to the mold body 1 so that the sealing ring disengages from the corresponding lower forming groove 11.

[0050] In the embodiment of the present application, the mold body 1 is used to be installed on a vulcanizer. When vulcanizing the sealing ring, first place the skeleton in the lower forming groove 11, then place the rubber raw material on the skeleton, and finally fit the cover plate 2 with the mold body 1 and push it into the vulcanizer for heat preservation and pressure holding for a certain period of time; after the sealing ring is vulcanized, the staff first operates the ring cutting assembly 4 to insert it into the waste groove 3 to separate the waste edge generated during the vulcanization of the sealing ring from the sealing ring, and then opens the cover plate 2. The staff operates the jacking assembly 5 to drive the sealing ring and the waste edge to move upward relative to the mold body 1 so that the sealing ring disengages from the corresponding lower forming groove 11. Finally, the staff removes the sealing ring and the waste edge from the top of the jacking assembly 5 to complete the blanking operation of the sealing ring.

[0051] Compared with the prior art, the vulcanizing mold for producing the sealing ring provided by the embodiment of the present application is more rapid and convenient in the operations of removing the waste edge and taking out the sealing ring, improves the blanking efficiency after the sealing ring is vulcanized, and at the same time avoids the direct contact between the staff and the vulcanizing mold, reducing the risk of scalding.

[0052] In some embodiments, please refer to Figures 1 to 6 As a specific implementation manner of the vulcanizing mold for producing the sealing ring provided by the present application, the cover plate 2 is provided with multiple groups of guide holes 22 corresponding one-to-one to the multiple upper forming grooves 21, and each group of guide holes 22 includes a plurality of guide holes 22 opened at the bottom of the waste groove 3 and arranged at intervals along the circumference of the upper forming groove 21; the ring cutting assembly 4 includes a plurality of tool holders 41 and a plurality of blades 42.

[0053] The plurality of tool holders 41 are slidably and fittingly connected to the corresponding plurality of guide holes 22 one-to-one; and each tool holder 41 can slide freely in the corresponding guide hole 22 independently.

[0054] The plurality of blades 42 are fixedly connected to the plurality of tool holders 41 one-to-one, and each blade 42 is located at one end of the tool holder 41 facing the waste groove 3; each blade 42 can be fixedly connected to the corresponding tool holder 41 in a welding form.

[0055] Wherein, when the sealing ring is embedded in the lower forming groove 11 and the cover plate 2 swings to fit with the upper side surface of the mold body 1, the corresponding plurality of blades 42 are all inserted into the waste edge, and the cutting edge of each blade 42 is located at the connection between the corresponding sealing ring and the waste edge, so as to prevent the blade 42 from cutting the sealing ring or making the waste edge not removed completely; at the same time, by moving each tool holder 41 around the central axis of the upper forming groove 21, each blade 42 can be moved along the circumference of the sealing ring.

[0056] By adopting the above technical solution, when the staff operates each tool holder 41 to move around the central axis of the upper forming groove 21 for one week, each blade 42 can move around along the connection between the corresponding sealing ring and the waste edge. The cutting edge of the blade 42 cuts open the connection between the sealing ring and the waste edge, realizing the separation of the sealing ring and the waste edge. Using the form of cutting with the blade 42 instead of manually tearing off the waste edge improves the efficiency of removing the waste edge and also avoids the staff being scalded by the sealing ring that is still in a high-temperature state after vulcanization is completed.

[0057] In some embodiments, please refer to Figure 1 , as a specific implementation manner of the vulcanization mold for producing sealing rings provided in this application, one end of each guiding hole 22 facing away from the waste slot 3 has a sliding slot 23 extending radially outward along itself, and each tool holder 41 has an operating handle 43 extending radially outward along itself and adapted to be embedded in the sliding slot 23; one or more operating handles 43 can be provided on each tool holder 41, and each operating handle 43 is rotatably connected to the corresponding tool holder 41.

[0058] By adopting the above technical solution, the staff can more conveniently apply an external force to each tool holder 41 by holding the operating handle 43.

[0059] In some embodiments, please refer to Figure 5 and Figure 6 , as a specific implementation manner of the vulcanization mold for producing sealing rings provided in this application, each blade 42 adopts a structure in which both the thickness and the width gradually decrease from the connection end to the insertion end.

[0060] By adopting the above technical solution, when each blade 42 moves circumferentially around the sealing ring, the angle between the inclined blade 42 and the waste edge is an acute angle, and the blade 42 can exert a greater shearing force on the waste edge, making the cutting step more labor-saving; the thickness of the insertion end of each blade 42 gradually decreases, which can avoid damaging the outer peripheral wall of the sealing ring or incomplete removal of the waste edge due to the excessive thickness of the blade 42.

[0061] In some embodiments, please refer to Figures 2 to 4 , as a specific implementation manner of the vulcanization mold for producing sealing rings provided in this application, the upper side surface of the mold body 1 also has a receiving groove 12 communicating with a plurality of lower forming grooves 11, and the jacking assembly 5 is arranged in the receiving groove 12.

[0062] By adopting the above technical solution, the jacking assembly 5 can move closer to or away from the mold body 1 in the vertical direction inside the receiving groove 12, and the receiving groove 12 can prevent the jacking assembly 5 from rotating around the central axis of the lower forming groove 11.

[0063] In some embodiments, please refer to Figure 5, as a specific embodiment of the vulcanization mold for producing the sealing ring provided in this application, the jacking assembly 5 includes a push plate 51 and a transmission rod 52.

[0064] The push plate 51 is slidably arranged in the accommodation groove 12 in the up and down direction, and the upper side surface of the push plate 51 has a plurality of first avoidance grooves 511 adapted to communicate with a plurality of lower forming grooves 11 for the sealing ring to be embedded, and a plurality of second avoidance grooves 512 communicating with a plurality of waste material grooves 3 for the waste edges to be embedded.

[0065] It should be added that each first avoidance groove 511 has the same shape and size as the corresponding lower forming groove 11, and each second avoidance groove 512 has the same shape and size as the corresponding waste material groove 3.

[0066] The transmission rod 52 is fixedly connected to the lower side surface of the push plate 51, and it penetrates through the bottom of the accommodation groove 12 and extends to the lower side of the mold body 1.

[0067] Among them, the transmission rod 52 is drivingly connected with a linear driving assembly 53.

[0068] By adopting the above technical solution, the linear driving assembly 53 can drive the transmission rod 52 to move in the up and down direction, thereby driving the push plate 51 to move towards or away from the mold body 1 in the up and down direction; when vulcanizing the sealing ring, the push plate 51 moves towards the mold body 1 until the upper surface of the push plate 51 coincides with the upper surface of the mold body 1; when discharging after the vulcanization of the sealing ring is completed, the linear driving assembly 53 drives the push plate 51 to move away from the mold body 1 until the sealing ring is separated from the lower forming groove 11.

[0069] In some embodiments, please refer to Figure 2 , as a specific embodiment of the vulcanization mold for producing the sealing ring provided in this application, the linear driving assembly 53 includes a linear cylinder fixedly connected to the bottom surface of the mold body 1 and drivingly connected with the transmission rod 52.

[0070] The linear cylinder has the advantages of simple structure, easy maintenance, high working efficiency, low maintenance cost, small volume, light weight, etc.

[0071] In some embodiments, please refer to Figure 3 and Figure 4 , as a specific embodiment of the vulcanization mold for producing the sealing ring provided in this application, a limiting structure 6 is provided between the cover plate 2 and the mold body 1, and the limiting structure 6 includes a plurality of convex columns 61 and a plurality of grooves 62.

[0072] A plurality of convex columns 61 are all arranged on the cover plate 2 and extend outward along the thickness direction of the cover plate 2; each convex column 61 adopts a conical structure with a gradually decreasing rod diameter along its extending direction.

[0073] A plurality of grooves 62 are all arranged on the mold body 1, and they correspond to the plurality of convex columns 61 one by one.

[0074] Wherein, when the cover plate 2 swings to fit with the upper side surface of the mold body 1, the plurality of convex columns 61 are inserted into the corresponding plurality of grooves 62 one by one.

[0075] By adopting the above technical solution, when the cover plate 2 swings towards the mold body 1, the convex column 61 with a conical structure can avoid bumping against the corresponding groove 62 and play a certain guiding role; the limiting structure 6 can prevent the cover plate 2 from shaking horizontally when it fits with the upper side surface of the mold body 1, improving the vulcanization quality of the sealing ring.

[0076] In some embodiments, please refer to Figures 1 to 4 together. As a specific implementation manner of the vulcanization mold for producing the sealing ring provided in this application, the upper side surface of the cover plate 2 further has a bearing platform 24 for connecting with the working part of the vulcanizing machine.

[0077] When performing the steps of closing the mold and putting it into the vulcanizing machine for heat preservation and pressure maintenance, the bearing platform 24 is used to connect with the working part of the vulcanizing machine to bear the pressure; moreover, the height of the bearing platform 24 is higher than the height of the ring cutting assembly 4, which can prevent the ring cutting assembly 4 from directly connecting with the working part of the vulcanizing machine, thereby causing the ring cutting assembly 4 to be damaged.

[0078] The technical solution adopted in this application also provides a vulcanizing machine, including the vulcanization mold for producing the sealing ring proposed in any one of the above.

[0079] The beneficial effects of the vulcanizing machine provided in this embodiment are the same as those of the aforementioned vulcanization mold for producing the sealing ring, and will not be elaborated here.

[0080] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included within the protection scope of this application.
