[0085] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0086] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0087] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0088] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0089] The following is combined with Figures 1-16 The following describes embodiments of the present invention.

[0090] According to embodiments of the present invention, a tire vulcanizing apparatus is provided, such as... Figure 1 , Figure 8 As shown, it includes an openable and closable tire vulcanizing mold and a chamber 1 formed in the tire vulcanizing mold. The chamber 1 is provided with a vulcanizing capsule installed in the tire vulcanizing mold. A tire to be vulcanized can be placed between the vulcanizing capsule and the inner wall of the tire vulcanizing mold for tire vulcanization operation.

[0091] Specifically, heated nitrogen gas is introduced into the vulcanizing bladder (not shown in the figure), or the nitrogen gas is introduced and then heated inside the vulcanizing bladder. The high-temperature nitrogen gas acts on the inside of the vulcanizing bladder to provide the heat required for vulcanization. At the same time, the nitrogen gas also provides the pressure required for vulcanization. The vulcanizing bladder expands and compresses the tire to be vulcanized. The tire is then shaped and vulcanized by the tire vulcanizing mold and the vulcanizing machine to improve the tire's strength. It should be noted that the tire vulcanizing equipment shown in the figure is only half of the complete machine structure.

[0092] The tire vulcanizing mold includes a fixed mold group 2 and a movable mold group 3. When the tire vulcanizing mold is opened, the movable mold group 3 can move relative to the fixed mold group 2.

[0093] Specifically, the inner wall of the fixed mold group 2 and the inner wall of the movable mold group 3 together form the chamber 1. When the tire vulcanization operation is performed, the tire vulcanization mold closes, and the chamber 1 forms a closed space; after the tire vulcanization operation is completed, the movable mold group 3 moves relative to the fixed mold group 2 so that the tire vulcanization mold opens, so that the vulcanized tire can be taken out.

[0094] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 As shown, the tire vulcanizing equipment also includes: heating element 4, temperature measuring element 5, power receiving contact 6, power supply contact 7, and cable 8.

[0095] Heating element 4 and / or temperature measuring element 5 are disposed on the fixed mold assembly 2 and near the chamber 1. Heating element 4 is used to provide heat for tire vulcanization operation, and temperature measuring element 5 is used to detect the temperature of tire vulcanization operation. Electrical contact 6 includes a first electrical contact 61 disposed on the fixed mold assembly 2 and near the movable mold assembly 3. The first electrical contact 61 is electrically connected to heating element 4 and / or temperature measuring element 5 through cable 8. Electrical contact 7 includes a first electrical contact 71 disposed on the movable mold assembly 3 corresponding to the first electrical contact 61. The first electrical contact 71 is electrically connected to external electrical control components through cable 8. When the tire vulcanization mold is closed, the first electrical contact 71 and the first electrical contact 61 contact and form an electrical connection. When the tire vulcanization mold is opened, the first electrical contact 71 and the first electrical contact 61 disengage and the electrical connection is broken.

[0096] In the above embodiment, a heating element 4, a temperature measuring element 5, and a first power receiving contact 61 electrically connected to the fixed mold group 2 via a cable 8 are provided, and a first power supply contact 71 electrically connected to an external electrical control component via a cable 8 is provided in the movable mold group 3. When the tire vulcanizing mold is closed, the heating element 4 and the temperature measuring element 5 can be transmitted to the heating element 4 and the temperature measuring element 5 through the contact between the first power supply contact 71 and the first power receiving contact 61. When the tire vulcanizing mold is opened, the first power supply contact 71 and the first power receiving contact 61 can be separated to quickly disconnect the circuit. In this way, the cable 8 does not need to be run between multiple molds, which solves the problem that the cable 8 is easily damaged by being pulled when the tire vulcanizing mold is opened and closed, making the tire vulcanizing equipment adaptable to frequent start-stop conditions.

[0097] Specifically, heating element 4 and temperature measuring element 5 are positioned near chamber 1 in the fixed mold assembly 2 so that after the tire to be vulcanized is placed, heating element 4 and temperature measuring element 5 can perform heat replenishment treatment and temperature detection at the tire bead position. In practical applications, one or both of heating element 4 and temperature measuring element 5 can be set as needed. Multiple sets of heating element 4 and temperature measuring element 5 can be set along the circumference of the fixed mold assembly 2.

[0098] Furthermore, one of the receiving contact 6 and the supply contact 7 is protruding, while the other is recessed or planar, to facilitate corresponding contact between the receiving contact 6 and the supply contact 7. In this embodiment, the supply contact 7 is protruding, while the receiving contact 6 is planar. The supply contact 7 employs several electrical springs arranged in a ring; the receiving contact 6 is made of a high-temperature resistant copper alloy or other highly conductive metal parts. This alloy can be used for a long time in high-temperature environments without oxidation or other corrosion reactions that affect conductivity.

[0099] Furthermore, when the vulcanized tire is removed from the vulcanizing mold, only the movable mold group 3 needs to move relative to the fixed mold group 2. Although the fixed mold group 2 consists of multiple mold parts, these parts do not shift relative to each other during mold opening. Therefore, when arranging the cable 8 in the fixed mold group 2, a continuous cable 8 can be directly threaded through the multiple mold parts in the fixed mold group 2 to electrically connect the first power receiving contact 61 to the heating element 4 and the temperature measuring element 5; or multiple discontinuous cable segments 8 can be arranged in the multiple mold parts of the fixed mold group 2, with the ends of the cable 8 connected through multiple sets of power receiving contacts 6 and power supply contacts 7 to electrically connect the first power receiving contact 61 to the heating element 4 and the temperature measuring element 5. The first power supply contact 71 is electrically connected to the external electrical control components via the cable 8. The electrical control components include an external power supply, a controller, and an electrical connector 19.

[0100] In some embodiments, such as Figure 4 , Figure 5, Figure 6 As shown, the first power receiving contact 61 is fixedly disposed on the fixed power receiving block 9, and the fixed power receiving block 9 is fixedly disposed on the fixed mold assembly 2; the first power supply contact 71 is fixedly disposed on the movable power supply block 10, and the movable power supply block 10 is movably disposed on the movable mold assembly 3 through the elastic member 11. The elastic member 11 is used to apply a force close to the fixed mold assembly 2 to the movable power supply block 10 so that the first power supply contact 71 and the first power receiving contact 61 abut against each other.

[0101] In the above embodiment, the fixed power receiving block 9 and the movable power supply block 10 provide a stable mounting base for the first power receiving contact 61 and the first power supply contact 71, respectively; the elastic element 11 applies a force close to the fixed mold assembly 2 to the movable power supply block 10 so that the first power supply contact 71 and the first power receiving contact 61 abut together, thereby ensuring that the first power supply contact 71 and the first power receiving contact 61 form a stable electrical connection and improving the stability of the vulcanization operation of the tire vulcanization equipment.

[0102] Specifically, the fixed receiving block 9 and the movable supplying block 10 are made of high-temperature resistant insulating materials, and only serve as the mounting base for the first receiving contact 61 and the first supplying contact 71.

[0103] Furthermore, the elastic element 11 is configured as a spring.

[0104] This embodiment provides a tire vulcanizing device with two configuration options: a first receiving contact 61 and a first supplying contact 71. That is, as... Figure 4 , Figure 5 , Figure 6 , Figure 7 The first embodiment of the first receiving contact 61 and the first supply contact 71 shown in the figure, and as shown in the figure... Figure 10 , Figure 11 , Figure 12 The second embodiment of the first power receiving contact 61 and the first power supply contact 71 shown.

[0105] The first embodiment of the configuration of the first receiving contact 61 and the first supplying contact 71 is described below.

[0106] In some embodiments, such as Figure 4 , Figure 7As shown, the movable power supply block 10 and the fixed power receiving block 9 are respectively arranged in the horizontal direction; the movable mold assembly 3 is provided with a slide groove 12, in which a movable wire plate 13 that can slide in the horizontal direction is provided, the movable wire plate 13 is provided with a first limiting groove 131, the movable power supply block 10 is movably arranged in the first limiting groove 131 in the vertical direction, and an elastic element 11 is connected between the inner wall of the first limiting groove 131 and the movable power supply block 10; the fixed mold assembly 2 is provided with a relief groove 14, and the fixed power receiving block 9 is located at the bottom of the relief groove 14; the movable wire plate 13 has a first position extending out of the slide groove 12 and a second position retracting into the slide groove 12; when the movable wire plate 13 is in the first position, the first power supply contact 71 and the first power receiving contact 61 contact and form an electrical connection; when the movable wire plate 13 is in the second position, the first power supply contact 71 and the first power receiving contact 61 disengage and the electrical connection is broken.

[0107] In the above embodiment, the movable power supply block 10 with the first power supply contact 71 and the fixed power receiving block 9 with the first power receiving contact 61 are respectively arranged in the horizontal direction. By the movable line plate 13 arranged in the movable mold group 3 cooperating with the relief groove 14 arranged in the fixed mold group 2, the first power supply contact 71 and the first power receiving contact 61 are electrically connected in the vertical direction.

[0108] Specifically, during the tire vulcanization process, the moving plate 13 is in the first position extending out of the slide groove 12. At this time, the first energizing contact 71 corresponds to the first energizing contact 61 at the bottom of the relief groove 14 and forms an electrical connection through contact, i.e. Figure 1 As shown. After the tire vulcanization is completed, when the tire vulcanization mold opens, as the movable mold group 3 moves relative to the fixed mold group 2, the movable line plate 13 can move away from the relief groove 14, causing the first power supply contact 71 and the first power receiving contact 61 to disengage and disconnect the electrical connection, i.e. Figure 3 As shown. When the mold needs to be disassembled, the moving plate 13 is in the second position of the retracted slide 12. At this time, the first power supply contact 71 is away from the relief groove 14 and retracted into the slide 12, which facilitates the protection of the first power supply contact 71 when disassembling the mold. The first power supply contact 71 is disengaged from the first power receiving contact 61 at the bottom of the relief groove 14 and the electrical connection is broken, that is, as shown. Figure 2 As shown.

[0109] Furthermore, in Figure 4From the perspective of the movable circuit board 13, a slot is provided at the lower part, and a first limiting cover plate 132 with an inwardly extending first limiting platform is installed at the slot, thereby forming a first limiting groove 131 together with the slot body; the outer edge of the movable power supply block 10 has a second limiting platform that extends outward. After the movable power supply block 10 is installed into the first limiting groove 131, the first limiting platform limits the second limiting platform, so that the movable power supply block 10 can be movably disposed in the first limiting groove 131 in the vertical direction without coming out of the first limiting groove 131. The elastic member 11 connecting the inner wall of the first limiting groove 131 and the movable power supply block 10 applies a force close to the fixed mold assembly 2, that is, vertically downward, to the movable power supply block 10, so that the first power supply contact 71 on the movable power supply block 10 and the first power receiving contact 61 on the fixed power receiving block 9 at the bottom of the clearance groove 14 stably abut against each other.

[0110] In some embodiments, such as Figure 4 , Figure 7 As shown, the bottom of the slide 12 is provided with a guide groove 121 in the horizontal direction, and the bottom of the moving plate 13 is provided with a guide positioning key 133 in the horizontal direction. The guide positioning key 133 slides in cooperation with the guide groove 121.

[0111] In the above embodiment, the guide positioning key 133 slides with the guide groove 121 to guide the movement of the moving line plate 13 in the slide groove 12, thereby improving the stability of the movement of the moving line plate 13 in the slide groove 12.

[0112] Specifically, a step is provided at one end of the guide groove 121 near the fixed mold assembly 2, and the guide positioning key 133 can abut against the step to prevent the moving plate 13 from dislodging from the slide groove 12 when it moves horizontally to the right.

[0113] In some embodiments, such as Figure 4 , Figure 7 As shown, the movable line plate 13 is provided with a through hole 134, and the bottom of the slide groove 12 is provided with a first mounting hole 122 and a second mounting hole 123 along the horizontal direction; when the movable line plate 13 is in the first position, the movable line plate 13 is fixed in the first position by the connector installed in the through hole 134 and the first mounting hole 122; when the movable line plate 13 is in the second position, the movable line plate 13 is fixed in the second position by the connector installed in the through hole 134 and the second mounting hole 123.

[0114] In the above embodiment, the bottom of the slide 12 is provided with a first mounting hole 122 and a second mounting hole 123, which are fixedly engaged with the through hole 134 on the moving line plate 13 through a connector in a timely manner, thereby limiting the moving line plate 13 when it is in the first position and the second position, and thus limiting the movement position of the first power contact 71.

[0115] Specifically, during tire vulcanization, the movable line plate 13 is in the first position extending out of the slide groove 12. The movable line plate 13 is fixed in this first position by a connector installed between the through hole 134 and the first mounting hole 122, ensuring that the position of the first power supply contact 71 on the movable line plate 13 is fixed, thus forming a stable electrical connection between the first power supply contact 71 and the first power receiving contact 61. When mold disassembly is required, the movable line plate 13 is in the second position retracted into the slide groove 12. The movable line plate 13 is fixed in this second position by a connector installed between the through hole 134 and the second mounting hole 123, ensuring that the position of the first power supply contact 71 on the movable line plate 13 is fixed in the slide groove 12 and will not slide out, thereby protecting the first power supply contact 71 during mold disassembly.

[0116] Furthermore, the connectors are set as bolts, screws, etc.

[0117] The following describes a second embodiment of the configuration of the first power receiving contact 61 and the first power supply contact 71.

[0118] In some embodiments, such as Figure 10 As shown, the movable power supply block 10 and the fixed power receiving block 9 are respectively arranged in the vertical direction; the side of the movable mold group 3 is provided with a first mounting groove 15, in which a first mounting base 16 is fixedly arranged, and the first mounting base 16 is provided with a second limiting groove 161. The movable power supply block 10 can be movably arranged in the second limiting groove 161 in the horizontal direction. An elastic element 11 is connected between the inner wall of the second limiting groove 161 and the movable power supply block 10; the side of the fixed mold group 2 is provided with a second mounting groove 17 corresponding to the position of the first mounting groove 15, in which a second mounting base 18 is fixedly arranged, and the fixed power receiving block 9 is fixedly arranged in the second mounting base 18.

[0119] In the above embodiment, the movable power supply block 10 with a first power supply contact 71 and the fixed power receiving block 9 with a first power receiving contact 61 are respectively arranged in the vertical direction. The first mounting base 16 provided in the movable mold group 3 cooperates with the second mounting base 18 provided in the fixed mold group 2 to realize the electrical connection between the first power supply contact 71 and the first power receiving contact 61 in the vertical direction.

[0120] Specifically, during tire vulcanization, the vulcanization mold closes. At this time, the first power supply contact 71 of the movable power supply block 10 on the first mounting base 16 corresponds to the first power receiving contact 61 of the fixed power receiving block 9 on the second mounting base 18, and forms an electrical connection through contact. Figure 8 As shown. After the tire vulcanization is completed, when the tire vulcanization mold opens, as the movable mold group 3 moves relative to the fixed mold group 2, the movable mold group 3 moves upward and away from the fixed mold group 2 at least partially, causing the first power supply contact 71 and the first power receiving contact 61 to disengage and disconnect the electrical connection, i.e., as shown.Figure 9 As shown.

[0121] Furthermore, in Figure 10 From the perspective of the first mounting base 16, a slot is provided on the right side, and a second limiting cover plate 162 with an inwardly extending third limiting platform is installed at the slot, thereby forming a second limiting slot 161 together with the slot body; the outer edge of the movable power supply block 10 has a fourth limiting platform that extends outward. After the movable power supply block 10 is installed into the second limiting slot 161, the third limiting platform limits the fourth limiting platform, so that the movable power supply block 10 can be movably disposed in the second limiting slot 161 in the horizontal direction without coming out of the second limiting slot 161.

[0122] Furthermore, the first mounting base 16 and the second mounting base 18 form a fitting clearance with the first mounting groove 15 and the second mounting groove 17 respectively, to ensure smooth and unobstructed movement during operation.

[0123] Furthermore, the second mounting base 18 has a certain up and down displacement function, which can meet the changes in the relative height between the movable mold group 3 and the fixed mold group 2 caused by preloading adjustment, and ensure that the first power supply contact 71 and the first power receiving contact 61 are always in uniform contact.

[0124] In some embodiments, such as Figure 10 , Figure 11 , Figure 12 As shown, one of the first mounting base 16 and the second mounting base 18 is provided with a positioning groove 163, and the other is provided with a positioning protrusion 181. The positioning groove 163 and the positioning protrusion 181 are correspondingly provided and located on the outer surfaces of the first mounting base 16 and the second mounting base 18 that are close to each other.

[0125] In the above embodiments, the positioning groove 163 and the positioning protrusion 181 are fitted together to limit the relative position of the first mounting base 16 and the second mounting base 18, so that when the movable mold group 3 rotates or moves to adjust its position relative to the fixed mold group 2, the first power supply contact 71 and the first power receiving contact 61 maintain a stable electrical connection.

[0126] Specifically, four positioning grooves 163 are provided at the four corners of the first mounting base 16, and four positioning protrusions 181 are provided at the four corners of the second mounting base 18.

[0127] Furthermore, the design of the positioning groove 163 and the positioning protrusion 181 can prevent frequent sliding friction between the first power supply contact 71 and the first power receiving contact 61 during the opening and closing of the tire vulcanizing mold. Specifically, before the positioning protrusion 181 and the positioning groove 163 are engaged during the opening and closing of the tire vulcanizing mold, the positioning protrusion 181 will contact the second limiting cover plate 162 of the first mounting base 16, so that the first power supply contact 71 and the first power receiving contact 61 do not contact each other, thereby avoiding sliding friction that would affect the service life; when the positioning protrusion 181 and the positioning groove 163 are engaged, the first power supply contact 71 and the first power receiving contact 61 can make normal contact again, realizing the electrical connection function.

[0128] In some embodiments, such as Figure 1 As shown, the fixed mold assembly 2 includes an upper cover 21, a base 22, a side plate, and a steel ring. The upper cover 21 and the base 22 are arranged opposite each other in the vertical direction, and the side plate and the steel ring are located between the upper cover 21 and the base 22. The heating element 4 and / or the temperature measuring element 5 are located on at least one of the side plate and the steel ring. The first power contact 61 is located on the upper cover 21. The movable mold assembly 3 includes an arc-shaped seat 31, a patterned block 32, a mounting ring 33, and a guide ring 34. The arc-shaped seat 31 and the patterned block 32 are located close to the side plate and the steel ring and can move synchronously in the horizontal direction. The mounting ring 33 and the guide ring 34 are located close to the arc-shaped seat 31 and the patterned block 32 and can move synchronously in the vertical direction. The first power contact 71 is located on the mounting ring 33.

[0129] In the above embodiment, the heating element 4 and the temperature measuring element 5 are disposed on the side plate and steel ring of the fixed mold assembly 2 near the chamber 1, so that after the tire to be vulcanized is placed, the heating element 4 and the temperature measuring element 5 can perform heat replenishment treatment and temperature detection at the tire bead position.

[0130] In some embodiments, such as Figure 1 , Figure 13 , Figure 14As shown, the side plate includes an upper side plate 23 and a lower side plate 24 arranged vertically opposite each other; the steel ring includes an upper steel ring 25 and a lower steel ring 26 arranged vertically opposite each other; the heating element 4 includes a first heating element 41 and a second heating element 42; the temperature measuring element 5 includes a first temperature measuring element 51 and a second temperature measuring element 52. The first heating element 41 and the first temperature measuring element 51 are respectively disposed on the upper steel ring 25 and / or the upper side plate 23; the second heating element 42 and the second temperature measuring element 52 are respectively disposed on the lower steel ring 26 and / or the lower side plate 24. 4; When one of the first heating element 41 and the first temperature measuring element 51 is located on the upper steel ring 25 and the other on the upper side plate 23, and one of the second heating element 42 and the second temperature measuring element 52 is located on the lower steel ring 26 and the other on the lower side plate 24; the power receiving contact 6 further includes a second power receiving contact 62, a third power receiving contact 63, a fourth power receiving contact 64 and a fifth power receiving contact 65, and the power supply contact 7 further includes a correspondingly provided second power supply contact 72, a third power supply contact 73, a fourth power supply contact 74 and a fifth power supply contact 65. The fifth power supply contact 75; the second power receiving contact 62 is located on the upper steel ring 25, the second power supply contact 72 and the third power receiving contact 63 are located on the upper side plate 23, the third power supply contact 73 is located on the upper cover 21, the fourth power receiving contact 64 is located on the lower steel ring 26, the fourth power supply contact 74 and the fifth power receiving contact 65 are located on the lower side plate 24, and the fifth power supply contact 75 is located on the base 22; one of the first heating element 41 and the first temperature measuring element 51 is electrically connected to the second power receiving contact 62 via a cable 8, and the other is connected to the third power receiving contact 65 via a cable 8. 3. The second power supply contact 72 and the third power receiving contact 63 are electrically connected via cable 8, and the third power supply contact 73 is electrically connected to the first power receiving contact 61 via cable 8; one of the second heating element 42 and the second temperature measuring element 52 is electrically connected to the fourth power receiving contact 64 via cable 8, and the other is electrically connected to the fifth power receiving contact 65 via cable 8; the fourth power supply contact 74 and the fifth power receiving contact 65 are electrically connected via cable 8, and the fifth power supply contact 75 is electrically connected to the external electrical control component via cable 8.

[0131] In the above embodiment, a set of heating elements 4 and temperature measuring elements 5 are respectively provided on the upper steel ring 25 and upper side plate 23, and on the lower steel ring 26 and lower side plate 24, so that the upper and lower bead positions of the tire can be heated and the temperature can be detected. Multiple discontinuous cables 8 are respectively provided on multiple mold parts of the fixed mold assembly 2. The ends of the cables 8 are connected through multiple sets of receiving contacts 6 and supply contacts 7, so that the first receiving contact 61 is electrically connected to the heating element 4 and the temperature measuring element 5. At the same time, the cables 8 do not affect the disassembly of the various mold parts of the fixed mold assembly 2, which facilitates the replacement and reassembly of the fixed mold assembly 2.

[0132] Specifically, since the fixed mold assembly 2 does not need to be moved during the vulcanization operation, the power receiving contacts 6 and power supply contacts 7 provided on each mold part of the fixed mold assembly 2 can be fixedly installed on the corresponding mold parts.

[0133] Furthermore, this embodiment does not limit the arrangement of the first heating element 41 and the first temperature measuring element 51 on the upper steel ring 25 and the upper side plate 23. In a first embodiment, both the first heating element 41 and the first temperature measuring element 51 are located on the upper steel ring 25; in a second embodiment, both are located on the upper side plate 23; and in a third embodiment, the first heating element 41 and the first temperature measuring element 51 are located on the upper steel ring 25 and the upper side plate 23, respectively. This embodiment adopts the third embodiment. The arrangement of the second heating element 42 and the second temperature measuring element 52 on the lower steel ring 26 and the lower side plate 24 is the same as the arrangement of the first heating element 41 and the first temperature measuring element 51 on the upper steel ring 25 and the upper side plate 23, and will not be repeated here.

[0134] Furthermore, since this embodiment uses the third implementation method described above to set the heating element 4 and the temperature measuring element 5, it is necessary to provide contact groups consisting of power receiving contacts 6 and power supply contacts 7 between the upper cover 21 and the upper side plate 23, between the upper side plate 23 and the upper steel ring 25, between the base 22 and the lower side plate 24, and between the lower side plate 24 and the lower steel ring 26. Figure 13 , Figure 14 The four sets of power receiving contacts 6 and power supply contacts 7 shown are designed to ensure that the upper cover 21, upper side plate 23, upper steel ring 25, lower steel ring 26, lower side plate 24 and base 22 can be freely disassembled without being affected by the cable 8.

[0135] In summary, for each mold part equipped with heating element 4 and temperature sensing element 5, a contact group consisting of receiving contact 6 and supply contact 7 needs to be installed between the mold part and adjacent mold parts. This ensures that each mold part can be freely disassembled without being affected by the cable 8 running through it.

[0136] Furthermore, the first power supply contact 71 is electrically connected to an external connector 19 via cable 8, and the fifth power supply contact 75 is electrically connected to another external connector 19 via cable 8.

[0137] In some embodiments, such as Figure 1 , Figure 15 , Figure 16As shown, the receiving contact 6 has at least a power receiving contact 66, a signal receiving contact 67, and a status judging contact 68, and the supply contact 7 has at least a power supply contact 76, a signal supply contact 77, and a status judging supply contact 78; the power receiving contact 66 and the power supply contact 76 are correspondingly arranged; the signal receiving contact 67 and the signal supply contact 77 are correspondingly arranged; and the status judging contact 68 and the status judging supply contact 78 are correspondingly arranged.

[0138] In the above embodiments, the receiving contact 6 and the supply contact 7 are each set to three different contact types to realize the power transmission, signal transmission and power transmission status judgment of the tire vulcanizing mold through the combination of cable 8 and contact.

[0139] Specifically, the power receiving contact 6 is provided with five locations at different positions: a first power receiving contact 61, a second power receiving contact 62, a third power receiving contact 63, a fourth power receiving contact 64, and a fifth power receiving contact 65. Each power receiving contact 6 has three different contact types: a power receiving contact 66, a signal receiving contact 67, and a status judgment receiving contact 68. The power supply contact 7 is set up in the same way.

[0140] Furthermore, multiple power receiving contacts 6 are provided for each of the three different contact types: power receiving contact 66, signal receiving contact 67, and status judgment receiving contact 68. This redundant design with multiple contacts allows for current shunting and resists load fluctuations.

[0141] Furthermore, this embodiment can be used not only for heating and temperature control of the side plates and steel rims, but also for heating and temperature measurement of other locations inside chamber 1. When used for temperature measurement of other locations inside chamber 1, simply replace the power cable with a temperature measuring cable, and create a corresponding number of contacts based on the type and quantity of the temperature measuring elements 5 in chamber 1 for signal transmission of temperature measurement in chamber 1. This solves the problem of difficult wiring for temperature measurement in the flexible mold chamber, enabling temperature monitoring inside the mold during tire vulcanization and better control of tire vulcanization quality.

[0142] In this embodiment, after the upper mold of the tire vulcanizing mold is raised, the upper cover 21 is lifted, and the tread blocks 32 can be controlled to close. When the tire vulcanizing mold is in the closed state, a set of contacts used for judging the state is turned on, transmitting a turn-on signal to the PLC. The PLC controls the power line to turn on and off based on real-time temperature detection. When the PLC detects that the contacts used for judging the state are turned off, it will not execute the power line energizing command, ensuring the safety of equipment and personnel and preventing electric shock accidents.

[0143] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
