Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a vulcanizing mold. Background Technology

[0002] During the vulcanization of tires, the mold needs to be heated. The existing heating method is steam heating. The mold is equipped with a connected steam chamber, steam inlet and steam outlet. When heating the mold, high-temperature steam enters through the steam inlet and fills the entire steam chamber, and finally exits through the steam outlet, thereby heating the mold.

[0003] In the above structure, high-temperature steam needs to be transported to the steam inlet through pipelines, resulting in a slow response speed for the heating mold. Furthermore, the high-temperature steam suffers heat loss during its passage through the pipelines due to heat dissipation from the pipelines and condensate drainage. On the other hand, the pipelines are equipped with various valve and sealing structures, leading to numerous maintenance points and making maintenance difficult.

[0004] Therefore, there is an urgent need to develop a vulcanization mold to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vulcanizing mold that can improve the heating efficiency of the mold body, reduce heat loss and maintenance difficulty, extend the insulation life of the insulation layer, and improve the uniformity of the circumferential temperature of the mold body.

[0006] To achieve this objective, the present invention adopts the following technical solution: A vulcanizing mold, comprising: The mold body has a first receiving groove on its side wall. The first receiving groove extends circumferentially along the mold body, and the opening of the first receiving groove is away from the inner cavity of the mold body. An electric heating assembly includes an electric heating tube, which is snapped into a first receiving groove, and the extending direction of the electric heating tube is the same as the extending direction of the first receiving groove. The insulation layer is wrapped around the side wall, and the electric heating tube is located between the insulation layer and the mold body. The side of the electric heating tube away from the bottom of the first receiving groove is spaced apart from the insulation layer. The side wall is also provided with a wiring groove. Along the extension direction of the first receiving groove, the first end and the last end of the first receiving groove are connected to the wiring groove. Along the extension direction of the electric heating tube, the first end and the last end of the electric heating tube are respectively the first wiring terminal and the second wiring terminal. The first wiring terminal and the second wiring terminal are both located in the wiring groove. The number of first receiving slots, wiring slots and electric heating components are multiple and correspond one-to-one. The orthographic projection of multiple wiring slots on the reference plane is evenly distributed along the circumference of the mold body, and the reference plane is perpendicular to the axis of the mold body.

[0007] Optionally, the vulcanizing mold also includes a temperature detection assembly and a controller. The temperature detection assembly includes a temperature detection element disposed on the side wall and adjacent to the electric heating tube. The temperature detection element is signal-connected to the controller, which can change the heating power of the electric heating tube.

[0008] Optionally, the vulcanizing mold also includes an electrical connector, the electric heating assembly also includes a first connecting wire, the electric heating tube is electrically connected to the electrical connector through the first connecting wire, and the temperature detection assembly also includes a second connecting wire, the temperature detection element is electrically connected to the electrical connector through the second connecting wire.

[0009] Optionally, the mold body is cylindrical, and there are multiple temperature detection components. The first receiving groove, the wiring groove, the electric heating component and the temperature detection component correspond one-to-one, and the electric heating tubes of the multiple electric heating components are evenly distributed along the axial direction of the mold body.

[0010] Optionally, the temperature sensing elements of the multiple temperature sensing components are distributed along the axial direction of the mold body.

[0011] Optionally, at least two adjacent electric heating components and a temperature detection component corresponding to the electric heating component form a wiring unit. A wiring groove is also provided on the side wall. The number of wiring grooves is equal to the number of wiring units and they correspond one-to-one. At least a portion of the first connecting wires and at least a portion of the second connecting wires in each wiring unit are located in a corresponding wiring groove.

[0012] Optionally, the electrical connector is a heavy-duty connector.

[0013] Optionally, the vulcanizing mold also includes a main body fixing member, which is connected to the side wall and abuts against the side of the electric heating tube opposite to the bottom of the first receiving tank. And / or, the electric heating assembly further includes two end fixing members, which are connected to the side wall and abut against the side of the electric heating tube opposite to the bottom of the first receiving groove. Along the extension direction of the first receiving groove, the two end fixing members of the electric heating assembly are respectively located on both sides of the wiring groove.

[0014] Optionally, the vulcanizing mold also includes a protective cover, which is placed on the side of the insulation layer away from the mold body.

[0015] The beneficial effects of this utility model are: This vulcanizing mold uses an electric heating element to heat the mold body, with the heating element directly embedded in the first receiving groove of the mold body. Compared to steam heating, electric heating offers a faster response time, and the direct contact between the heating element and the mold body improves heating efficiency. Furthermore, electricity, as a clean energy source, reduces environmental pollution during tire vulcanization, making it more environmentally friendly. Secondly, the mold body's sidewalls are wrapped with an insulation layer, and the electric heating element is located between the insulation layer and the mold body. The side of the heating element facing away from the bottom of the first receiving groove is spaced apart from the insulation layer, thus achieving insulation for both the mold body and the heating element, reducing heat loss, and ensuring the insulation performance and lifespan of the insulation layer. Thirdly, compared to steam heating, this vulcanizing mold eliminates the need for pipelines transporting high-temperature steam, valve structures, and sealing structures. Therefore, maintenance of these pipelines, valve structures, and sealing structures is unnecessary, reducing maintenance points and simplifying maintenance. Finally, since the wiring slot only contains the first and second terminals, and these terminals cannot effectively heat the mold body, the mold body at the location of the wiring slot is not heated. The orthographic projections of multiple wiring slots onto the reference plane are evenly distributed along the circumference of the mold body, and the reference plane is perpendicular to the axis of the mold body. This ensures that the unheated areas of the mold body are distributed circumferentially, thereby improving the circumferential temperature uniformity of the mold body. Attached Figure Description

They are used only for ease of description and simplification of operation, 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] This embodiment provides a vulcanizing mold that can improve the heating efficiency of the mold body, reduce heat loss and maintenance difficulty, extend the insulation life of the insulation layer, and improve the uniformity of the circumferential temperature of the mold body.

[0023] Specifically, such as Figures 1 to 3As shown, the vulcanizing mold includes a mold body 1, an electric heating component 2, and a heat insulation layer 3. The mold body 1 has a first receiving groove on its side wall 11, which extends circumferentially along the mold body 1 and has its opening facing away from the inner cavity of the mold body 1. The electric heating component 2 includes an electric heating tube 21, which is snapped into the first receiving groove and extends in the same direction as the first receiving groove. The heat insulation layer 3 is wrapped around the side wall 11, and the electric heating tube 21 is located between the heat insulation layer 3 and the mold body 1. The side of the electric heating tube 21 facing away from the bottom of the first receiving groove is spaced apart from the heat insulation layer 3. The side wall 11 is also provided with a wiring groove 111. Along the extension direction of the first receiving groove, the first end and the end of the first receiving groove are connected to the wiring groove 111. Along the extension direction of the electric heating tube 21, the first end and the end of the electric heating tube 21 are respectively the first wiring terminal 211 and the second wiring terminal 212. The first wiring terminal 211 and the second wiring terminal 212 are both located in the wiring groove 111. There are multiple first receiving grooves, wiring grooves 111 and electric heating components 2, and they correspond one-to-one. For example, the number of wiring grooves 111 can be two, three, four or more. The orthographic projection of multiple wiring grooves 111 on the reference plane (not shown in the figure) is evenly distributed along the circumference of the mold body 1. The reference plane is perpendicular to the axis of the mold body 1.

[0024] The vulcanizing mold uses an electric heating tube 21 to heat the mold body 1, and the electric heating tube 21 is directly inserted into the first receiving groove of the mold body 1, thereby achieving efficient heating of the mold body 1. Secondly, the side wall 11 of the mold body 1 is wrapped with a heat insulation layer 3, and the electric heating tube 21 is located between the heat insulation layer 3 and the mold body 1, thereby achieving a heat insulation effect for the mold body 1 and the electric heating tube 21 and reducing heat loss. The side of the electric heating tube 21 facing away from the bottom of the first receiving groove is spaced apart from the heat insulation layer 3, that is, the depth of the first receiving groove is greater than the diameter of the electric heating tube 21. This structure can prevent the heat insulation layer 3 from contacting the electric heating tube 21, thus ensuring the heat insulation performance and service life of the heat insulation layer 3. Furthermore, compared with the steam heating structure, this vulcanizing mold eliminates the need for pipelines for conveying high-temperature steam, valve structures on the pipelines, and sealing structures. Therefore, there is no need to maintain the pipelines, valve structures, and sealing structures, achieving the effect of reducing maintenance points and reducing maintenance difficulty. Finally, a wiring groove 111 is formed on the side wall 11, and both the first terminal 211 and the second terminal 212 are located within the wiring groove 111 to facilitate wiring operations of the first terminal 211 and the second terminal 212 within the wiring groove 111. Since only the first terminal 211 and the second terminal 212 are provided in the wiring groove 111, and the heat generated by the first terminal 211 and the second terminal 212 is very small (it may not even have a heating effect on the mold body 1), the mold body 1 is not heated by the electric heating tube 21 at the location of the wiring groove 111. Compared to the distribution of multiple wiring grooves 111 along the axial direction of the mold body 1, in this embodiment, the orthographic projection of multiple wiring grooves 111 on the reference plane is uniformly distributed along the circumference of the mold body 1, which can make the unheated positions of the mold body 1 distributed in the circumferential direction of the mold body 1, thereby improving the temperature uniformity of the mold body 1 in the circumferential direction. Optionally, as Figure 1 and Figure 2 As shown, the vulcanizing mold also includes a protective cover 8, which is placed on the side of the insulation layer 3 away from the mold body 1 to protect the insulation layer 3.

[0025] Optionally, the vulcanizing mold also includes a temperature detection assembly 4 and a controller (not shown in the figure). The temperature detection assembly 4 includes a temperature detection element 41, which is disposed on the side wall 11 and adjacent to the electric heating tube 21. The temperature detection element 41 is signal-connected to the controller, which can change the heating power of the electric heating tube 21. The temperature detection element 41 is used to detect the mold temperature near the electric heating tube 21. The controller controls the heating power of the electric heating tube 21 based on the actual temperature detected by the temperature detection element 41, thereby controlling the heating temperature of the mold body 1. Furthermore, using a controller to control the heating power of the electric heating tube 21 can improve the control accuracy of the heating power of the electric heating tube 21, thereby improving the temperature accuracy of the mold body 1.

[0026] It should be noted that the above-mentioned method of the controller changing the heating power of the electric heating tube 21 is the prior art in this field. For example, a preset temperature can be input into the controller in advance. After the temperature detection element 41 detects the actual temperature of the mold body 1 and transmits the actual temperature to the controller, the controller compares the actual temperature with the preset temperature. When the actual temperature is less than the preset temperature, the controller increases the heating power of the electric heating tube 21 to increase the heating amount of the mold body 1.

[0027] Furthermore, the temperature sensing element 41 can be a common element in the art, such as a resistance temperature detector (RTD).

[0028] Optionally, such as Figures 1 to 3 As shown, the vulcanizing mold also includes an electrical connector 5, and the electric heating assembly 2 also includes a first connecting line 22. The electric heating tube 21 is electrically connected to the electrical connector 5 via the first connecting line 22. The temperature detection assembly 4 also includes a second connecting line 42, and the temperature detection element 41 is electrically connected to the electrical connector 5 via the second connecting line 42. Both the first connecting line 22 of the electric heating assembly 2 and the second connecting line 42 of the temperature detection assembly 4 are electrically connected to the same electrical connector 5, simplifying the wiring structure of the first connecting line 22 and the second connecting line 42, while also reducing the number of electrical connectors 5, which helps to further reduce maintenance points and lower maintenance difficulty.

[0029] In this embodiment, the electric heating component 2 includes two first connecting wires 22, which are respectively connected to the first terminal 211 and the second terminal 212.

[0030] Furthermore, the electrical connector 5 is connected to the protective cover 8 on the side away from the insulation layer 3, which improves the overall integration of the vulcanizing mold and makes it easier to further reduce maintenance difficulty.

[0031] Furthermore, the electrical connector 5 is a heavy-duty connector (i.e., a heavy-duty plug). The heavy-duty connector has a high protection level and can effectively resist dust, moisture, corrosion and mechanical shock. In addition, the heavy-duty connector has high current and voltage carrying capacity, wide operating temperature range, excellent vibration resistance and long mating life, which provides a guarantee for the reliable electrical connection between the first connecting line 22 and the second connecting line 42 and the heavy-duty connector.

[0032] Optionally, the mold body 1 is cylindrical, and there are multiple temperature detection components 4. The first receiving groove, wiring groove 111, electric heating component 2, and temperature detection component 4 correspond one-to-one. The electric heating tubes 21 of the multiple electric heating components 2 are evenly distributed along the axial direction of the mold body 1. This even distribution of the electric heating tubes 21 along the axial direction of the mold body 1 improves the temperature uniformity of the mold body 1 in the axial direction. Furthermore, the orthographic projection of the multiple wiring grooves 111 on the reference plane is evenly distributed along the circumference of the mold body 1. Therefore, this structure can evenly heat the mold body 1 in both the axial and circumferential directions, thus improving the overall temperature uniformity of the mold body 1. It should be noted that the number of electric heating components 2 can be two, three, four, or more, depending on the axial dimension of the mold body 1. This embodiment uses four electric heating components 2 as an example for illustration.

[0033] Optionally, the temperature sensing elements 41 of the multiple temperature sensing components 4 are distributed along the axial direction of the mold body 1, so that the multiple temperature sensing elements 41 are concentrated on the mold body 1, which makes it easier to further reduce maintenance difficulty and improve maintenance efficiency.

[0034] Optionally, the vulcanizing mold also includes a main body fixing member 7, which is connected to the side wall 11 and abuts against the side of the electric heating tube 21 away from the bottom of the first receiving groove. The main body fixing member 7 can press the electric heating tube 21 into the first receiving groove and make the electric heating tube 21 fit tightly against the bottom of the first receiving groove, ensuring that the electric heating tube 21 can efficiently heat the mold body 1.

[0035] Furthermore, the main fixing part 7 extends along the axial direction of the mold body 1, and all electric heating tubes 21 abut against the main fixing part 7, thereby achieving the pressing effect on all electric heating tubes 21. In addition, the structure of the main fixing part 7 is relatively regular, which helps to reduce the difficulty of maintenance.

[0036] Furthermore, the main body fixing member 7 is connected to the side wall 11 by a plurality of first screws 91. For example, the main body fixing member 7 can be connected to the side wall 11 by two, three or more first screws 91. Specifically, the plurality of first screws 91 are evenly distributed along the extension direction of the main body fixing member 7, and the side wall 11 of the mold body 1 is provided with a plurality of first threaded holes. Each first screw 91 passes through the protective cover 8, the heat insulation layer 3 and the main body fixing member 7, and is threadedly engaged with a corresponding first threaded hole, thereby realizing the connection between the main body fixing member 7 and the side wall 11 of the mold body 1, and also realizing the connection between the heat insulation layer 3 and the protective cover 8 and the mold body 1.

[0037] Optionally, there may be multiple main body fasteners 7. For example, there may be two, three, four or more main body fasteners 7. Multiple main body fasteners 7 are evenly distributed along the circumference of the mold body 1 to improve the pressing effect on the electric heating tube 21. Furthermore, since multiple main body fasteners 7 are evenly distributed along the circumference of the mold body 1, the heating uniformity of the electric heating tube 21 along the circumference of the mold body 1 is improved.

[0038] It should be noted that in this embodiment, the side of the electric heating tube 21 away from the bottom of the first receiving groove is spaced apart from the insulation layer 3, that is, the electric heating tube 21 is recessed in the first receiving groove. In order to make the main body fixing member 7 press the electric heating tube 21 tightly in the first receiving groove, the side wall 11 of the mold body 1 is also provided with a second receiving groove. The number of the second receiving grooves is equal to the number of the main body fixing members 7 and corresponds one-to-one. Each main body fixing member 7 is located in a corresponding second receiving groove so that the main body fixing member 7 can abut against the side of the electric heating tube 21 away from the bottom of the first receiving groove.

[0039] Optionally, the electric heating assembly 2 further includes two end fixing members 23. The end fixing members 23 are connected to the side wall 11 and abut against the side of the electric heating tube 21 opposite to the bottom of the first receiving groove. Along the extending direction of the first receiving groove, the two end fixing members 23 of the electric heating assembly 2 are respectively located on both sides of the wiring groove 111. This presses the position of the electric heating tube 21 near the first wiring end 211 and the position near the second wiring end 212 into the first receiving groove, so that the positions of the electric heating tube 21 near the first wiring end 211 and the position near the second wiring end 212 are both in close contact with the bottom of the first receiving groove, ensuring that the electric heating tube 21 can efficiently heat the mold body 1.

[0040] Furthermore, the end fixing member 23 is connected to the side wall 11 by two second screws 92. Specifically, the two second screws 92 are located on both sides of the width direction of the first receiving groove. Each second screw 92 passes through the protective cover 8, the heat insulation layer 3 and the main fixing member 7, and is threaded into a corresponding second threaded hole on the side wall 11 to realize the connection between the end fixing member 23 and the side wall 11 of the mold body 1. At the same time, it also realizes the connection between the heat insulation layer 3 and the protective cover 8 and the mold body 1.

[0041] It should be noted that in this embodiment, the side of the electric heating tube 21 away from the bottom of the first receiving groove is spaced apart from the insulation layer 3, that is, the electric heating tube 21 is recessed in the first receiving groove. In order to make the end fixing member 23 press the electric heating tube 21 into the first receiving groove, a third receiving groove is also provided on the side wall 11 of the mold body 1. The number of the third receiving grooves is equal to that of the end fixing members 23 and they correspond one-to-one. Each end fixing member 23 is located in a corresponding third receiving groove so that the end fixing member 23 can abut against the side of the electric heating tube 21 away from the bottom of the first receiving groove.

[0042] Optionally, such as Figure 4 As shown, at least two adjacent electric heating components 2 and the temperature detection component 4 corresponding to the electric heating component 2 form a wiring unit 6. That is, see [link to diagram]. Figure 1 and Figure 4 The wiring unit 6 includes at least two electric heating components 2 and at least two temperature detection components 4. The number of electric heating components 2 and temperature detection components 4 is equal within the same wiring unit 6. Furthermore, the temperature detection element 41 of each temperature detection component 4 is arranged adjacent to the electric heating tube 21 of a corresponding electric heating component 2 within the same wiring unit 6. A wiring groove 112 is also provided on the side wall 11. The number of wiring grooves 112 is equal to the number of wiring units 6 and they correspond one-to-one. At least a portion of the first connecting lines 22 and at least a portion of the second connecting lines 42 in each wiring unit 6 are located within a corresponding wiring groove 112. This allows several adjacent electric heating components 2 and temperature detection components 4 to be combined into one wiring unit 6, and the first connecting lines 22 and second connecting lines 42 within the same wiring unit 6 to share a single wiring groove 112. This results in a more organized layout of all connecting lines on the mold body 1, reducing both maintenance and wiring difficulties.

[0043] In this embodiment, there are two wiring troughs 112, that is, there are two wiring units 6. Each wiring unit 6 includes two electric heating components 2 and two temperature detection components 4. Of course, in other embodiments, the number of wiring troughs 112 can also be one, three, or four, etc. In the same wiring unit 6, the number of electric heating components 2 can be three, four, or more. And when there are more than two wiring units 6, the number of electric heating components 2 in different wiring units 6 can be the same or different.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
