Description

Technical Field

[0001] This utility model belongs to the field of tire production technology and equipment, and in particular relates to an electromagnetic heating vulcanization device for making solid tires. Background Technology

[0002] Hot plate vulcanizing machines are characterized by low steam consumption and high heat transfer efficiency. However, this structural type does not fundamentally solve the long-standing drawbacks in the tire vulcanization process. Most of the steam heat is dissipated during pipeline circulation, resulting in significant energy waste. The steam heat from the upper and lower hot plates must undergo a slow conduction process to reach the side plates and rims. The middle mold sleeve also suffers from low heat transfer efficiency. The uneven distribution of air and metal in the radial direction of the outer mold significantly affects the uniformity of heat transfer. Generally, the preheating process for a newly replaced mold takes 3-5 hours, resulting in very low heat transfer efficiency. The presence of the steam chamber also increases the manufacturing cost of the outer mold, and the outer mold is susceptible to steam corrosion during long-term use, affecting its service life. Currently, electromagnetic induction heating technology, characterized by rapid and uniform heating, is rapidly emerging and developing, and is gradually being applied to tire vulcanization production. However, current applications are limited to improvements based on existing hot plate vulcanizing machine molds, and further improvements in energy saving are needed.

[0003] For example, Chinese patent literature discloses an electromagnetic induction heating coil plate and equipment for a tire vulcanizing machine hot plate [patent application number: CN202320058736.9], which includes a heating coil plate fixed on a hot plate. The coil plate includes a coil plate housing, a coil plate cover plate that is fastened to the coil plate housing, several magnetic strips, and several sets of coils. The magnetic strips are fixedly installed inside the coil plate housing, and the coils are laid on the magnetic strips. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing an electromagnetic heating vulcanization device for manufacturing solid tires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electromagnetic heating vulcanizing device for manufacturing solid tires includes two outer mold sleeves connected by a middle heating plate. An upper heating plate and a lower heating plate are provided on the side of the two outer mold sleeves away from the middle heating plate. Electromagnetic heating coil assemblies are provided in the upper heating plate, the lower heating plate and the middle heating plate. Several electromagnetic heating coil assemblies are also provided on the side of the mold cavity inside the outer mold sleeve.

[0007] The electromagnetic heating vulcanizing device for making solid tires described above also includes a central shaft, which passes through two outer mold sleeves and is located at the center of the outer mold sleeves. An electromagnetic heating coil assembly is also provided inside the central shaft.

[0008] In the aforementioned electromagnetic heating vulcanizing device for making solid tires, the central shaft is composed of a cavity and an outer wall. A heating rod is movably connected inside the cavity. The electromagnetic heating coil assembly is mounted on the heating rod. The heating rod is driven by a rotating structure to move close to the outer wall and around the outer wall.

[0009] In the aforementioned electromagnetic heating vulcanizing device for making solid tires, a gear ring is provided on the inner top ring of the cavity, a main gear is provided at the center of the top of the cavity, a driven gear is meshed between the main gear and the gear ring, the heating rod is fixed on the driven gear, and the main gear is externally connected to a rotational power source.

[0010] In the electromagnetic heating vulcanizing device for making solid tires described above, the bottom of the cavity is provided with an anti-rotation structure connected to the heating rod, and the heating rod is rotatably connected to the driven gear.

[0011] In the aforementioned electromagnetic heating vulcanizing device for making solid tires, the anti-rotation structure includes a limiting disc disposed at the bottom of the cavity, a limiting ring groove provided between the limiting disc and the bottom of the cavity, a surrounding curved block slidably connected in the limiting ring groove, and a heating rod fixedly connected to the surrounding curved block.

[0012] In the aforementioned electromagnetic heating vulcanizing device for making solid tires, a number of through-hole shafts are also provided inside the outer mold sleeve, and the through-hole shafts penetrate the mold cavity.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] Two sets of outer mold sleeves share a central heating plate. The central heating plate is equivalent to the lower heating plate of the upper outer mold sleeve and the upper heating plate of the lower outer mold sleeve. Compared with the traditional method where each outer mold sleeve needs both upper and lower heating plates, this method can save the energy consumed by one heating plate per unit of operation.

[0017] The central shaft passes through the outer mold sleeve and the mold cavity. During heating, it can heat the middle part of the mold cavity, improve the heating speed and temperature stability, thereby ensuring quality and improving work efficiency.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides an electromagnetic heating vulcanizing device for manufacturing solid tires, combined with... Figure 1-4 As shown, it includes two outer mold sleeves 10, which are connected by a middle heating plate 11. An upper heating plate 12 and a lower heating plate 13 are provided on the side of the two outer mold sleeves away from the middle heating plate 11. Electromagnetic heating coil assemblies 14 are provided in the upper heating plate 12, the lower heating plate 13 and the middle heating plate 11. Several electromagnetic heating coil assemblies 14 are also provided on the side of the mold cavity inside the outer mold sleeve 10.

[0026] In this embodiment, the two outer mold sleeves 10 share a common intermediate heating plate 11. The intermediate heating plate 11 is equivalent to the lower heating plate 13 located on the upper outer mold sleeve 10 and the upper heating plate 12 located on the lower outer mold sleeve 10. Compared with the traditional method where each outer mold sleeve 10 requires both upper and lower heating plates, this method can save the energy consumed by one heating plate per unit of work during operation.

[0027] It also includes a central shaft 15, which passes through the two outer mold sleeves 10 and is located at the center of the outer mold sleeves 10. An electromagnetic heating coil assembly 14 is also provided inside the central shaft 15.

[0028] In this embodiment, the central shaft 15 is inserted into the outer mold sleeve 10 and the mold cavity. During heating, it can heat the middle part of the mold cavity, improve the heating speed and temperature stability, thereby ensuring quality and improving work efficiency.

[0029] The central shaft 15 is composed of a cavity 16 and an outer wall. A heating rod 17 is movably connected inside the cavity 16. The electromagnetic heating coil assembly 14 is disposed on the heating rod 17. The heating rod 17 is driven by a rotating structure 18 to move close to the outer wall and around the outer wall.

[0030] In this embodiment, the central shaft 15 can have a large outer diameter. During heating, the heating rod 17 moves around the outer wall of the cavity 16 to continuously dissipate heat to the surroundings, thereby improving temperature stability.

[0031] The cavity 16 has a toothed ring on the top inner ring, and a main gear 19 is provided at the top center of the cavity 16. A driven gear 20 is meshed between the main gear 19 and the toothed ring. The heating rod 17 is fixed on the driven gear 20. The main gear 19 is externally connected to a rotational power source.

[0032] The cavity 16 has an anti-rotation structure 21 at the bottom that is connected to the heating rod 17, and the heating rod 17 is rotatably connected to the driven gear 20.

[0033] In this embodiment, since the heating rod 17 needs to move with the gear 20 and the heating rod 17 is connected to the wire, the anti-rotation structure 21 is used to prevent the heating rod 17 from rotating and to prevent the wire from getting tangled.

[0034] The anti-rotation structure 21 includes a limiting disk 22 disposed at the bottom of the cavity 16, a limiting ring groove 23 provided between the limiting disk 22 and the bottom of the cavity 16, a surrounding curved block 24 slidably connected in the limiting ring groove 23, and the heating rod 17 fixedly connected to the surrounding curved block 24.

[0035] The outer mold sleeve 10 is also provided with a number of through-hole shafts 25, which penetrate the mold cavity.

[0036] In this embodiment, the through-hole shaft 25 is used to form through holes on the tire for subsequent fixation with the support ring.

[0037] The upper heating plate 12, lower heating plate 13 and middle heating plate 11 extend outward to form an outer mold sleeve 10, and a fixing rod 26 passes through the portions of the upper heating plate 12, lower heating plate 13 and middle heating plate 11 that extend outward to form the outer mold sleeve 10.

[0038] In this embodiment, the connection stability between the two outer mold sleeves 10 is improved.

[0039] Both ends of the fixing rod 26 that extend out of the heating plate are fitted with threaded sleeves.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0041] Although this article frequently uses terms such as outer mold sleeve 10, intermediate heating plate 11, upper heating plate 12, lower heating plate 13, electromagnetic heating coil assembly 14, central shaft 15, cavity 16, heating rod 17, drive structure 18, main gear 19, driven gear 20, anti-rotation structure 21, limiting disc 22, limiting ring groove 23, surrounding curved block 24, through hole shaft 25, fixing rod 26, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
