[0045] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in combination with the drawings.
[0046] In the first aspect, please refer to Figure 1 — Figure 3 One embodiment of the heat preservation structure for tire vulcanization provided by the utility model comprises a heat preservation part. The heat preservation part comprises an inner heat preservation layer 1 and an outer heat preservation layer 3, and an inner heat radiation reflection layer 2 is arranged between the inner heat preservation layer 1 and the outer heat preservation layer 3.
[0047] The inner heat preservation layer 1 is directly close to or in contact with the tire mold 6 and is wrapped on the outer side of the tire mold 6; therefore, in order to adapt to the shape of the tire mold 6, the inner heat preservation layer 1 needs to have a certain softness. For example, the inner heat preservation layer 1 uses flexible heat preservation materials including but not limited to polyimide foam materials, ceramic fiber felt, aluminum silicate fiber felt, basalt fiber felt and glass fiber felt, so that the inner heat preservation layer 1 is in close contact with the outer side of the tire mold 6, thereby achieving the best heat preservation effect.
[0048] The inner heat radiation reflection layer 2 is located on the outer side of the inner thermal insulation layer 1, can reflect the heat escaping from the inner thermal insulation layer 1, and to a certain extent reduces the air circulation, effectively improves the insulation effect, and reduces the heat loss. The material of the inner heat radiation reflection layer 2 can be a reflective foam, an aluminum foil or other reflective thermal insulation materials with a certain shape structure. At this time, the inner heat radiation reflection layer 2 is stacked with the inner thermal insulation layer 1 or connected with the inner thermal insulation layer 1. The preferred connection mode of the inner heat radiation reflection layer 2 and the inner thermal insulation layer 1 is bonding, that is, the inner heat radiation reflection layer 2 is pasted on the outer side of the inner thermal insulation layer 1 by using high-temperature resistant glue, that is, the structure of the inner heat radiation reflection layer 2 and the inner thermal insulation layer 1 is not damaged, and stable connection can also be achieved. The inner heat radiation reflection layer 2 can also use reflective thermal insulation paint with heat reflection function, and the reflective thermal insulation paint is coated on the outer side of the inner thermal insulation layer 1.
[0049] The material of the outer thermal insulation layer 3 is a thermal insulation material with a thermal conductivity less than 0.03 W / (m.k) at 25°C. The low thermal conductivity of the thermal insulation material enhances the overall thermal insulation effect of the thermal insulation structure. For example, the material of the outer thermal insulation layer 3 is aerogel felt, ceramic fiber or the like.
[0050] It is found in practice that by arranging the inner heat radiation reflection layer 2, better thermal insulation effect can be achieved without significantly increasing the thickness of the thermal insulation structure. In addition, the inner heat radiation reflection layer 2 is located between the inner thermal insulation layer 1 and the outer thermal insulation layer 3, which avoids damaging the inner heat radiation reflection layer 2 and affecting the thermal insulation effect. Again, the inner heat radiation reflection layer 2 is not located on the outer layer, and a large amount of heat is accumulated when the inner heat radiation reflection layer 2 works. If the inner heat radiation reflection layer 2 is placed on the outer layer, the heat dissipation speed is fast, which affects the thermal insulation effect.
[0051] Further, the outer side of the outer thermal insulation layer 3 is also provided with a plurality of groups of reinforced thermal insulation layer groups 4, and the plurality of groups of reinforced thermal insulation layer groups 4 are stacked or connected as a whole. The reinforced thermal insulation layer group 4 adjacent to the outer thermal insulation layer 3 can also be connected with the outer thermal insulation layer 3, but the stacking without connection does not affect the thermal insulation effect. The number of the reinforced thermal insulation layer groups 4 can be set according to the actual use needs. For example, as shown in FIG. 4, the outer side of the outer thermal insulation layer 3 is also provided with a group of reinforced thermal insulation layer groups 4. Figure 1
[0052] Each group of reinforced thermal insulation layer groups 4 includes a reinforced thermal insulation layer 42. The material of the reinforced thermal insulation layer 42 is a thermal insulation material with a thermal conductivity less than 0.03 W / (m.k) at 25°C, such as aerogel felt, ceramic fiber or the like. The material of the outer thermal insulation layer 3 and the reinforced thermal insulation layer 42 can be the same or different. However, it is preferred that the material of the outer thermal insulation layer 3 and the reinforced thermal insulation layer 42 is the same, which is convenient for production and manufacturing, and reduces the production materials.
[0053] Preferably, the inner side of the reinforced thermal insulation layer 42 is provided with a reinforced thermal radiation reflection layer 41. The material of the reinforced thermal radiation reflection layer 41 is a reflective thermal insulation material or a reflective thermal insulation coating, including but not limited to special reflective foam, aluminum foil, etc., which can further reduce the radiation heat loss of the tire mold 6.
[0054] In practice, it is found that one layer of reinforced thermal radiation reflection layer 41 cooperates with the inner thermal radiation reflection layer 2 to reduce the temperature of the outer side of the thermal insulation part by 5%~10% under the condition that the internal temperature of the tire mold 6 is 180-200℃, and the effect is very obvious. Therefore, for the thermal insulation structure, the number of reinforced thermal radiation reflection layers 41 is preferably 1~2 layers, i.e. the number of reinforced thermal insulation layers 42 is preferably 1~2 layers.
[0055] Further, the interval between the two adjacent reinforced thermal radiation reflection layers 41 or the interval between the inner thermal radiation reflection layer 2 and the innermost reinforced thermal radiation reflection layer 41 (i.e. the thickness of the reinforced thermal insulation layer 42 and the outer thermal insulation layer 3) is 3~15mm, and the best is 6~10mm.
[0056] Similarly, the reinforced thermal insulation layer group 4 and the outer thermal insulation layer 3 and the two adjacent reinforced thermal insulation layer groups 4 can also be used by bonding or directly stacking.
[0057] Further, the outer side of the thermal insulation part is provided with a protective part to protect the thermal insulation part inside it from wear and tear, etc. As an embodiment of the protective part, the protective part includes an outer skin 5.
[0058] Please refer to Figures 1-3 , the outer skin 5 at least has a first protective layer 51, which is located on the outer side of the radial direction of the thermal insulation part to protect the thermal insulation part inside it. Preferably, as Figure 3 shown, the outer skin 5 also has a second protective layer 53, which is located on the inner side of the radial direction of the thermal insulation part; the second protective layer 53 is spliced with the first protective layer 51 to form a closed protective cavity inside, and the thermal insulation part is completely in the protective cavity. For example, the third protective layer 52, the fourth protective layer 54, the fifth protective layer 55 and the sixth protective layer 56 are respectively arranged at the upper edge, the lower edge and the left and right edges of the second protective layer 53 and the first protective layer 51, and the first protective layer 51 and the second protective layer 53 are connected through the third protective layer 52, the fourth protective layer 54, the fifth protective layer 55 and the sixth protective layer 56 to form a closed outer skin 5. The mutual connection of the outer skin 5 is spliced by sewing, bonding, etc.
[0059] Further, the outer skin 5 is spliced by at least two materials, the first protective layer 51, the third protective layer 52 and the fourth protective layer 54 which are easy to be knocked are made of high-temperature-resistant and flame-retardant cloth with high tear resistance, including but not limited to aramid cloth, reinforced carbon fiber cloth, steel wire reinforced cloth, aluminum foil cloth, etc., wherein the scratch-resistant steel wire reinforced cloth is preferred; the second protective layer 53, the fifth protective layer 55 and the sixth protective layer 56 are made of common silica gel coated cloth or Teflon coated cloth and other high-temperature-resistant and flame-retardant cloth, which improves the protection of the outer skin 5 under the premise of controlling the cost.
[0060] Obviously, the outer skin 5 can also be made of steel wire reinforced cloth as a whole, or the fifth protective layer 55 and the sixth protective layer 56 are made of steel wire reinforced cloth, but the steel wire has good heat conduction and cannot achieve the optimal heat insulation state.
[0061] The outer skin 5 can be further provided with a drawstring and a lining inside the outer skin 5 to enhance the function and strength of the outer skin 5; the lining inside the outer skin 5 can improve the tear resistance of the sewing area.
[0062] On the other hand, referring to Figure 4 Another embodiment of the tire mold provided by the utility model comprises a heat preservation sleeve 61 and a guide ring 62, the heat preservation sleeve 61 is sleeved outside the guide ring 62 and covers the circumferential surface of the guide ring 62. The heat preservation sleeve 61 adopts the heat preservation structure described above, is well combined with the guide ring 62 and has more excellent energy-saving effect; the outer skin 5 has strong protection and is resistant to impact and scratching.
[0063] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can be changed and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
