Description

Technical Field

[0001] This utility model relates to the field of tire mold technology, specifically to a tire mold with high-efficiency heat transfer. Background Technology

[0002] Tire molds are key components used in tire vulcanization, determining the tire's quality, performance, and cost. During tire vulcanization, heat is transferred from external heat sources such as hot plates or steam chambers to the tire carcass for vulcanization and molding.

[0051] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0052] Please refer to Figure 1 This invention provides an embodiment of a high-efficiency heat transfer tire mold, comprising a mold body, which includes a slider 107, a cavity forming assembly, an upper cover 106, and a base 109. The cavity forming assembly is used to form the cavity surface and includes a tread block 101, a lower side plate 102, a lower steel ring 103, an upper steel ring 104, and an upper side plate 105. The mold body is prior art, therefore its structure will not be described in detail.

[0053] To overcome the problems of slow heat transfer and significant heat loss in the existing technology during the process of heat transfer from the external heat source 108 to the tire blank, the tire mold is also equipped with a heat-conducting component. The heat-conducting component includes at least several slider heat-conducting elements 201. Please refer to... Figures 2-5 The slider 107 has several through holes 202. The side of the slider 107 that mates with the patterned block 101 is the inner side, and the side that mates with the heat source 108 is the outer side. The through holes 202 penetrate the slider 107 and are open on both the inner and outer sides. The slider heat conductor 201 is embedded in the through hole 202. The size of the slider heat conductor 201 is designed to be as large as possible along the length of the through hole 202. For example, the inner end face of the slider heat conductor 201 can abut against the outer side of the patterned block 101, resulting in high contact heat transfer efficiency. The slider heat conductor 201 transfers the heat from the heat source 108 to the patterned block 101 with high heat transfer efficiency and minimal heat loss in between.

[0054] The shape of the slider through-hole 202 can be cylindrical, honeycomb, rectangular, etc. The shape of the slider heat conductor 201 matches the slider through-hole 202; therefore, it is preferable that the slider through-hole 202 is cylindrical, which facilitates the processing, fitting, and assembly of the slider heat conductor 201 and the slider through-hole 202. For the slider 107, its internal slider through-hole 202 can be as follows... Figure 2 , Figure 4 and Figure 5 As shown, the slide holes 202 are spaced apart along the axial direction of the mold body. Figure 2 As shown, the slider through-hole 202 is inclined from top to bottom within the slider 107, moving from the outside in. Furthermore, while ensuring the basic function of the slider 107, the slider through-hole 202 is funnel-shaped, meaning that the inner diameter of one end is smaller than that of the other end; it can be as follows... Figure 4 As shown, the outer end inner diameter of the slider through hole 202 is smaller than its inner end inner diameter, or as... Figure 5 As shown, the inner diameter of the slider through-hole 202 is smaller than the inner diameter of its outer end; one end of the slider heat conductor 201 can form a larger contact surface, which is beneficial to improving heat transfer efficiency. Figure 3 As shown, several slider through holes 202 are also distributed at intervals in the circumferential direction of the mold body.

[0055] The heat conductor assembly also includes a top cover heat conductor 205; please refer to... Figure 6 The upper cover 106 has through holes 206 machined through its upper and lower sides, and the upper cover heat conductor 205 is fixedly installed in the upper cover through hole 206. The upper cover heat conductor 205 matches the upper cover through hole 206, which can be cylindrical, honeycomb, rectangular, etc., preferably cylindrical. The two end faces of the upper cover heat conductor 205 are preferably flush with the upper and lower sides of the upper cover 106.

[0056] The heat conductor assembly also includes a base heat conductor 207; please refer to Figure 7 The base 109 has a base through hole 208 that penetrates the base 109 and has openings on both the upper and lower sides of the base 109. A base heat conductor 207 is fixedly installed within the base through hole 208, and the base heat conductor 207 matches the base through hole 208. The base through hole 208 can be cylindrical, honeycomb, rectangular, etc., but is preferably cylindrical. The two end faces of the base heat conductor 207 are preferably flush with the upper and lower sides of the base 109.

[0057] The base heat conductor 207, the top cover heat conductor 205, and the slider heat conductor 201 are made of high thermal conductivity materials. High thermal conductivity materials have the characteristics of fast mass transfer and rapid heat conduction. Through the base heat conductor 207, the top cover heat conductor 205, and the slider heat conductor 201, heat from the outside of the mold body can be quickly transferred to the cavity forming components, providing heat for the vulcanization of the tire blank. Furthermore, by rationally distributing the base heat conductor 207, the top cover heat conductor 205, and the slider heat conductor 201, the vulcanization temperature at different locations on the tire blank can be controlled to obtain the best vulcanization effect and a high yield. High thermal conductivity materials are not limited to silicon carbide; they can also be aluminum alloys, copper alloys, aluminum nitride, etc.

[0058] Since the through hole 206 in the upper cover, the through hole 208 in the base, and the through hole 202 in the slider are interconnected, in order to prevent the base heat conductor 207, the upper cover heat conductor 205, and the slider heat conductor 201 from loosening during heat transfer, a fixing structure can be used to fix the base heat conductor 207, the upper cover heat conductor 205, and the slider heat conductor 201. For example, as... Figure 8 As shown, the fixing structure is set as a baffle 301, which is fixed to the slider 107, the upper cover 106, or the base 109 by screws 302. Preferably, the end faces of the base heat conductor 207, the upper cover heat conductor 205, and the slider heat conductor 201 are provided with clearance portions, and one side of the upper cover through hole 206, the base through hole 208, and the slider through hole 202 is provided with a groove. The groove connects to the upper cover through hole 206, the base through hole 208, or the slider through hole 202. The baffle 301 can be embedded in the groove and abut against the clearance portion, effectively preventing loosening and not affecting the integrity of the surfaces of the upper cover 106, the base 109, and the slider 107.

[0059] Furthermore, such as Figure 9-15 As shown, the heat-conducting component also includes one or more of the following: patterned block heat-conductor 203, upper steel ring heat-conductor 209, lower steel ring heat-conductor 211, lower side plate heat-conductor 213, and upper side plate heat-conductor 215. Correspondingly, the patterned block 101 is provided with a patterned block mounting hole 204, the upper steel ring 104 is provided with an upper steel ring mounting hole 210, the lower steel ring 103 is provided with a lower steel ring mounting hole 212, the lower side plate 102 is provided with a lower side plate mounting hole 214, and the upper side plate 105 is provided with an upper side plate mounting hole 216. Since the inner surface of the cavity forming component is the cavity surface, the patterned block mounting hole 204, upper steel ring mounting hole 210, lower steel ring mounting hole 212, lower side plate mounting hole 214, and upper side plate mounting hole 216 are blind holes extending from the outside to the inside, and none of them open on the cavity surface. The patterned block heat conductor 203 is fixed in the patterned block mounting hole 204, the upper steel ring heat conductor 209 is fixed in the upper steel ring mounting hole 210, the lower steel ring heat conductor 211 is fixed in the lower steel ring mounting hole 212, the lower side plate heat conductor 213 is fixed in the lower side plate mounting hole 214, and the upper side plate heat conductor 215 is fixed in the upper side plate mounting hole 216.

[0060] The pattern block mounting hole 204, the upper steel ring mounting hole 210, and the lower steel ring mounting hole 212 can be cylindrical, honeycomb, rectangular, etc., and are preferably cylindrical.

[0061] The lower side plate mounting holes 214 and the upper side plate mounting holes 216 can be cylindrical, honeycomb, rectangular, or arc-shaped. They can be spaced apart or continuously arranged as a whole to maximize the heat-receiving area while ensuring strength.

[0062] The tread block mounting holes 204 can be set in zones according to the tire vulcanization temperature. During tire vulcanization, the transition area between the tire sidewall and the tread requires a higher temperature. Therefore, the position and diameter of the tread block mounting holes 204 can be set according to different vulcanization requirements to achieve the effect of zoned vulcanization. Preferably, some of the tread block mounting holes 204 on the tread block 101 correspond to and overlap with the slider through holes 202 in the slider 107, which facilitates rapid and efficient heat transfer.

[0063] For slider 107, when there is a need for vertical heat transfer, the heat from the upper and lower parts of slider 107 is transferred to the interior of slider 107. A heat-conducting block 217 can be installed inside slider 107, extending vertically. For example, a heat-conducting block mounting hole 218 is machined on the upper or lower side of slider 107, and the heat-conducting block 217 is fixed within the heat-conducting block mounting hole 218. The heat-conducting block mounting holes 218 can be spaced apart along the circumference of the mold body, allowing the heat-conducting block mounting holes 218 to penetrate slider 107 vertically. Figure 16 and 17 As shown; the heat-conducting block mounting hole 218 can be set as an annular shape. In this case, the heat-conducting block mounting hole 218 cannot pass vertically through the slider 107, such as... Figure 18 and Figure 19 As shown.

[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
