DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] In this embodiment, if Figure 1-Figure 6 As shown, a tire mold for avoiding tire rubber edge includes a pattern block 1, an upper side plate 2, and a lower side plate 3. The pattern block 1, the upper side plate 2, and the lower side plate 3 are all integrated structures to ensure the airtightness of the mold. The rubber cannot penetrate through the interface, thereby avoiding the occurrence of rubber edge phenomenon. The upper side plate 2 and the lower side plate 3 are symmetrically arranged on the upper and lower sides of the pattern block 1. The pattern block 1 is fixedly connected to the upper side plate 2 and the lower side plate 3 by a plurality of bolts. The pattern block 1 is further fitted to the side plate by bolts to reduce the gap generated at the connection, thereby reducing the overflow of rubber during the extrusion process, which is beneficial to the processing of the tire, and the pattern block 1 and the upper side plate 2 are connected. A mold parting surface 4 is formed at the connection position between the side plate 2 and the pattern block 1 and the lower side plate 3, and also includes a glue storage groove 5 and a glue overflow groove 6. The glue storage groove 5 is arranged on the mold parting surface 4 to improve the glue storage capacity of the mold. The glue overflow groove 6 is arranged in the middle of the pattern block 1 to reduce the rubber edge of the tire. Through the glue storage groove 5 and the glue overflow groove 6, the rubber overflowed during the vulcanization of the tire carcass can flow into the storage part 52 and the slide groove 61 along the mold parting surface 4, thereby realizing the storage of the overflowed rubber, improving the glue storage capacity of the mold, and the overflowed rubber can be cut after forming a rubber edge, thereby improving the neatness of the appearance of the tire;

[0028] Among them Figure 2 and Figure 3As shown, the glue storage tank 5 includes an extension portion 51, which is arranged at the connection position between the pattern block 1 and the upper side plate 2 and the lower side plate 3. A storage portion 52 is arranged on the side of the extension portion 51 away from the mold parting surface 4 to prevent the formation and accumulation of glue edges at the mold parting surface 4 between the pattern block 1 and the side plate, ensure the parallelism between the mold and the tire material, and prevent excessive glue from causing tire deformation, thereby affecting subsequent operations;

[0029] Among them Figure 4-Figure 6 As shown, the overflowing rubber groove 6 includes a slide groove 61, and a fixing plate 62 is provided on one side of the slide groove 61 away from the pattern block 1. A cutter 63 is rotatably connected to one side of the fixing plate 62, and the rubber edge is cut by the cutter 63, so as to ensure the quality of the finished tire. The cutter 63 is in contact with the fixing plate 62 and is not fixed. The rotating shaft of the cutter 63 is fixedly connected to a rotating rod 64, and a turning handle is provided at one end of the turning rod 64. The turning handle is connected to the pattern block 1 by a fastening bolt. When the connecting rod 65 contacts the clamping groove 67 and rotates to a certain angle, the position of the turning handle is fixed by the fastening bolt. At this time, the glue inlet hole corresponds to the through hole. A clamping piece is fixedly installed on the outer side of the turning rod 64, which is convenient for disassembling the cutter 63 and taking out the rubber material.

[0030] Among them Figure 4-Figure 6 As shown, the clamping member includes a connecting rod 65, and a movable groove 66 adapted to the connecting rod 65 is provided on the inner wall of the slide 61, so as to facilitate the sliding of the connecting rod 65 out. A clamping groove 67 is connected to the side of the movable groove 66 close to the fixed plate 62, so that the cutter 63 and the slide 61 are detachably connected, which is convenient for the staff to replace the cutter 63 and clean the rubber inside the slide 61, and effectively increases the practicality of the mold;

[0031] Among them Figure 1 As shown, sealing gaskets are provided at the connection positions of the pattern block 1 and the upper side plate 2 and the lower side plate 3 to increase the overall sealing effect of the mold;

[0032] Among them Figure 3 As shown, the shape of the extension part 51 is cylindrical, the depth of the extension part 51 is set to b, b is 5-10 mm, the diameter of the extension part 51 is set to a, a is 0.25-0.5 mm, and the storage part 52 accommodates more rubber material, so that the rubber material will not enter the gap between the mold parting surfaces 4, avoiding the formation of thin rubber edges, and the cylindrical rubber strip inside the extension part 51 has a certain thickness, which can be easily separated from the tire completely, and is convenient to separate from the finished tire, avoiding rubber residue, which is conducive to improving the appearance qualification rate of the tire;

[0033] Among them Figure 5 and Figure 6As shown, a plurality of glue inlet holes are evenly distributed on the surface of the fixing plate 62, and a plurality of through holes are provided on the surface of the cutting knife 63. The through holes correspond to the positions of the glue inlet holes, so that the glue material can enter the interior of the slide 61 through the glue inlet holes and the through holes, so as to facilitate the processing of the glue edge.

[0034] Example 2

[0035] The difference from Example 1 is that Figure 7 and Figure 8 As shown, the rubber storage tank 5 also includes an arc groove 53 connected to the extension part 51, and a cutting blade 54 is slidably connected inside the arc groove 53. The cutting blade 54 fits the side panel plane at the rubber storage tank 5. The arc groove 53 is adapted to the specifications and dimensions of the cutting blade 54. A push handle 55 is fixedly connected to one end of the cutting blade 54, which is convenient for removing the rubber edge along the circumference of the rubber edge, thereby improving the efficiency of rubber edge trimming without damaging the outer surface of the tire, thereby improving the neatness of the appearance of the tire after vulcanization.

[0036] When in use, first fix the position of the tread block 1 and the side panel by bolts, and then inject the rubber. Due to the integrated structure of the tread block 1 and the side panel, the overflowed rubber flows into the rubber storage tank 5 and the overflow rubber tank 6 along the mold parting surface 4, thereby achieving the rubber storage effect. Before demolding the tire, the user loosens the fastening bolts, turns the handle to drive the cutter 63 to rotate, and then cuts the rubber inside the overflow rubber tank 6. The user pushes the push handle 55 to make the cutting blade 54 move along the arc groove 53, and then cuts the rubber inside the rubber storage tank 5, which is convenient for taking out the rubber and improving the quality of the tire.

[0037] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
