Description

Technical Field

[0001] This utility model relates to the component structure of a tire shaping and vulcanizing machine, specifically an electromagnetic heating plate device for a tire shaping and vulcanizing machine. Background Technology

[0002] Traditional hot plate heating primarily relies on saturated steam for heating. However, steam production is energy-intensive, and the long steam delivery pipelines result in significant energy losses. Compared to steam heating, electric heating (using heating elements or electromagnetic coils) offers greater advantages. It eliminates heat losses in intermediate stages, provides faster heating, is easier to maintain, and has lower overall costs.

[0003] During tire vulcanization, a hot plate is needed to evenly heat the tire mold, which requires ensuring uniform temperature across the entire hot plate, especially the electromagnetic heating plate. Furthermore, because the mounting holes for molds of different sizes vary, many holes need to be drilled in the hot plate, affecting the arrangement of the electromagnetic coils on the mounting plate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electromagnetic heating plate device for a tire shaping vulcanizing machine, which not only ensures uniform temperature across the entire heating plate but also meets the installation requirements of molds of different sizes.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] The electromagnetic heating plate device of the tire shaping vulcanizing machine includes a hot plate, a mounting plate, a heat insulation plate, fastening screws, an electromagnetic coil, a slider, and connecting screws. The hot plate, mounting plate, and heat insulation plate are arranged sequentially from bottom to top and connected to the vulcanizing machine body by fastening screws. The mounting plate has several annular grooves for installing the electromagnetic coil on the side near the heat insulation plate. The hot plate has several T-shaped grooves radially on the side near the mold. The slider is locked in the T-shaped grooves. The mold is fixedly connected to the slider by connecting screws.

[0007] Furthermore, the number of T-slots is four.

[0008] Furthermore, the number of electromagnetic coils installed in the mounting plate is 2 to 10, and each group contains 1 to 20 coils.

[0009] Furthermore, the width of the annular groove matches the width of a single coil.

[0010] Compared with the prior art, the advantages and effects of this utility model are:

[0011] 1. The heating plate is heated by an electromagnetic coil. By rationally arranging the size of the inner annular groove of the mounting plate and the number of electromagnetic coils, the uniformity of heating the tire mold by the hot plate is effectively improved, and the energy consumption of the tire vulcanization process is greatly reduced.

[0012] 2. The installation method between the mold and the hot plate has been improved. Instead of drilling holes in the hot plate, a T-slot and slider are used, which makes it easy to adapt to molds of different sizes. At the same time, it avoids the problem of the coil arrangement inside the mounting plate being affected by too many mounting holes. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0017] The electromagnetic heating plate device for the tire shaping vulcanizing machine described in this embodiment, such as Figure 1 As shown, the system includes a hot plate 1, a mounting plate 2, a heat insulation plate 3, fastening screws 4, an electromagnetic coil 5, a slider 6, and connecting screws 7. The hot plate 1, mounting plate 2, and heat insulation plate 3 are arranged sequentially from bottom to top and are connected and fixed to the vulcanizing machine body by fastening screws 4 evenly distributed along the circumference. The mounting plate 2 has several annular grooves for mounting the electromagnetic coils 5 on the side near the heat insulation plate 3. The hot plate 1 has four symmetrically distributed T-shaped grooves along the radial direction on the side near the mold 8. Figure 2 The slider 6 is fitted into the T-slot and has a threaded hole. The connecting screw 7 fixes the mold 8 to the slider 6, thereby connecting the mold 8 to the hot plate 1. The slider 6 can slide in the T-slot to meet the installation requirements of molds of different sizes.

[0018] In this embodiment, the mounting plate 2 and the heat insulation plate 3 are both made of high-strength, high-temperature resistant heat insulation resin (or glass fiber). Their function is to reduce heat conduction to the outside and prevent the electromagnetic coil from heating the vulcanizing machine body, thereby reducing heat loss. The hot plate 1 is made of carbon steel.

[0019] To ensure that the mounting plate 2 can withstand the clamping force of the vulcanizing machine of several hundred tons and increase the force-bearing area, the width of the annular groove should be as narrow as possible. In this embodiment, the width of the annular groove is matched with the width of a single coil (i.e., each annular groove can only accommodate one coil).

[0020] In this embodiment, the electromagnetic coil 5 is made of copper and is installed in the annular groove of the mounting plate 2. There are 2 to 10 groups of electromagnetic coils 5, each group containing 1 to 20 coils, all connected in series. An external electromagnetic heating controller 9 is connected to each electromagnetic coil 5, and the electromagnetic heater controller 8 can control all electromagnetic coils 5. When the electromagnetic heating controller 9 is activated, a high-frequency, high-voltage current is applied to the electromagnetic coils 5, generating an electromagnetic field that induces eddy currents inside the hot plate 1, causing it to heat up. By rationally arranging the number of groups and coils of electromagnetic coils 5, the hot plate 1 heats up evenly, ultimately meeting the requirement for uniform heating of the tire mold.
