[0002] The hot plates, serving as the outer molds of the tire vulcanizing machine, are installed at the top and bottom of the movable mold. They consist of an upper hot plate and a lower hot plate, and their function is to heat and vulcanize the tire sidewall within the mold. Currently, a steam / nitrogen vulcanization process is commonly used for tire vulcanization. This process involves introducing high-temperature steam into the inner and outer molds to heat them, causing the tire blank to heat up and vulcanize through heat conduction.

[0003] Currently, most electromagnetic heating devices for tire vulcanizing machines on the market have an integrated electromagnetic plate and heating plate structure. Although some parts are divided into multiple areas to achieve multi-zone heating, the overall size is mostly fixed. Therefore, when processing tires of different diameters, the entire heating plate needs to be replaced, which is not easy. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is a multi-zone heating tire vulcanizing machine hot plate electromagnetic heating device, including vulcanizing machine body 1, base 2 fixed in the middle of the surface of vulcanizing machine body 1, and bracket 3 fixed in the top of base 2.

[0027] It also includes: a sliding groove 4 is provided on the inner side wall of the bracket 3, a positioning hole 5 is provided on the upper surface of the bracket 3, the positioning holes 5 are equidistantly distributed along the upper surface of the bracket 3, a first assembly block 6 is distributed on the inner side of the bracket 3, a second assembly block 7 is distributed at one end of the first assembly block 6, a third assembly block 8 is distributed at the other end of the second assembly block 7, and a fourth assembly block 9 is distributed at the end of the third assembly block 8 away from the second assembly block 7. The sides of the fourth assembly block 9, the third assembly block 8, the second assembly block 7 and the first assembly block 6 that are close to each other are all arc-shaped surfaces, and the multiple assembly blocks are installed in sequence from small to large during subsequent installation. A slider 10 is fixedly provided on the side wall of the first assembly block 6, and a return spring 11 is fixedly connected to the inner cavity of the slider 10. The two ends of the return spring 11 are respectively fixedly connected to the bottom of the positioning rod 12 and the inner side wall of the slider 10. The other end of the return spring 11 is fixedly connected to the positioning rod 12, and an auxiliary sliding plate 13 is sleeved on the outer side of one end of the positioning rod 12.

[0028] During operation, the fourth assembly block 9, the third assembly block 8, the second assembly block 7, and the first assembly block 6 are sequentially engaged and connected to the inner side of the bracket 3 in ascending order of size. When an assembly block engages with the bracket 3, the assembly block drives the symmetrically arranged sliders 10 on both sides to slide along the grooves 4 opened on the inner wall of the bracket 3, thereby improving the stability of the assembly block during movement. After the assembly block moves to the designated position, the sliders 10 move to below the positioning hole 5. At this time, the positioning rod 12 is located directly below the positioning hole 5, so an application force is applied to the positioning rod 12. Once the longitudinal pressure disappears, the reverse force generated by the deformation of the return spring 11 will push the positioning rod 12 in the opposite direction, thereby inserting one end of the positioning rod 12 into the inner side of the positioning hole 5 to achieve the positioning of the assembly block. While the positioning rod 12 moves longitudinally, it will drive the auxiliary slide plate 13 to slide inside the slider 10, thereby improving the stability of the positioning rod 12 during movement. When installing the assembly block, the assembly block can be selectively installed according to different usage requirements, which makes it convenient to be used with tires of different sizes, and the overall practicality is higher.

[0029] A hot plate body 14 is distributed above the first assembly block 6, and a heat insulation plate 15 is fixed at the bottom of the hot plate body 14. The heat insulation plate 15 is made of high temperature resistant epoxy resin to prevent the electromagnetic coil 21 from directly contacting the hot plate body 14, which would cause the electromagnetic coil 21 to age prematurely, break, or leak electricity, thus affecting the heating quality. At the same time, it can also prevent the heat generated by the electromagnetic coil 21 working for a long time from affecting the temperature field of the hot plate body 14 and reduce the heat loss of the hot plate near the substrate. A plug rod 16 is fixed on one side of the bottom of the heat insulation plate 15, and a cross-shaped locking block 17 is fixed in the middle of the bottom end of the heat insulation plate 15.

[0030] During operation, the hot plate body 14 drives the heat insulation plate 15 to move longitudinally. Then, the hot plate body 14 drives the heat insulation plate 15 to engage with the first assembly block 6. The insertion rod 16 is inserted into the inside of the slot 19 to achieve positioning of the hot plate body 14. The cross-shaped locking block 17 engages with the fixing post 20 to improve the engagement stability and provide guidance to prevent positional deviation of the hot plate body 14 during engagement.

[0031] The inner side of the first assembly block 6 is provided with a groove 18, and the bottom side of the groove 18 is connected to a slot 19. The slots 19 are symmetrically distributed along the vertical center line of the first assembly block 6, and the size of the slots 19 is adapted to the size of the insert rod 16. A fixing post 20 is fixed in the middle of the inner cavity of the first assembly block 6, and an electromagnetic coil 21 is distributed on the bottom side of the fixing post 20. A cross groove with a diameter adapted to the size of the cross-shaped locking block 17 is provided on the top of the fixing post 20.

[0032] During operation, the heat insulation plate 15 is engaged with the inner side of the groove 18 to achieve positioning of the heat plate body 14. At the same time, the insert rods 16, which are symmetrically distributed along the heat insulation plate 15, are inserted into the inner side of the slot 19 to further position the heat insulation plate 15 and ensure the stability of the engagement between the heat insulation plate 15 and the assembly block. Since the top of the fixing post 20 has a cross groove, and the size of the cross groove is adapted to the size of the cross locking block 17, when the cross locking block 17 engages with the cross groove on the top of the fixing post 20, it can ensure that the heat insulation plate 15 will not shift in position during installation. During operation, the electromagnetic coil 21 generates heat, which facilitates the subsequent processing of the tire.

[0033] The positioning holes 5 are evenly distributed along the upper surface of the bracket 3, and the positioning holes 5 and the bracket 3 form an integrated structure.

[0034] During operation, since the positioning holes 5 are evenly distributed on the upper surface of the bracket 3, and the size of the positioning holes 5 is compatible with the size of the positioning rod 12, the positioning rod 12 can be inserted into the inner side of the positioning hole 5 to achieve separate positioning of multiple assembly blocks.

[0035] The first assembly block 6 is slidably connected to the bracket 3 via slider 10, and the slider 10 is symmetrically distributed on both sides of the first assembly block 6.

[0036] During operation, when the first assembly block 6 is connected to the bracket 3, the first assembly block 6 will drive the slider 10 to slide along the groove 4 opened on the inner side wall of the bracket 3, thereby improving the stability of the first assembly block 6 during movement.

[0037] The positioning rod 12 is slidably connected to the slider 10 through the return spring 11, and the outer diameter of the positioning rod 12 is adapted to the inner diameter of the positioning hole 5.

[0038] During operation, the reverse force generated by the deformation of the return spring 11 will drive the positioning rod 12 to move longitudinally inside the slider 10, which facilitates the subsequent input of one end of the positioning rod 12 into the inside of the positioning hole 5.

[0039] Working principle: First, the heat insulation plate 15 is engaged inside the groove 18, achieving positioning of the heat plate body 14. Simultaneously, the insertion rod 16 is inserted into the slot 19, further positioning the heat insulation plate 15 and ensuring the stability of the engagement between the heat insulation plate 15 and the assembly block. Since the top of the fixing post 20 has a cross groove, and the size of the cross groove matches the size of the cross locking block 17, when the cross locking block 17 engages with the cross groove on the top of the fixing post 20, it ensures that the heat insulation plate 15 will not shift during installation. The fourth assembly block 9, the third assembly block 8, the second assembly block 7, and the first assembly block 6 are then sequentially engaged and connected to the inner side of the bracket 3 in ascending order. When the assembly block moves to the designated position, the slider 10 moves to the bottom of the positioning hole 5. At this time, the positioning rod 12 is located directly below the positioning hole 5. Then, the return spring 11 pushes the positioning rod 12 in the opposite direction, inputting one end of the positioning rod 12 into the inner side of the positioning hole 5 to achieve the positioning of the assembly block. During operation, the electromagnetic coil 21 generates heat, which facilitates the subsequent processing of the tire.

[0040] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
