During the use of steam and thermal oil, long pipelines, heat dissipation, steam or oil leakage are unavoidable problems.

[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0026] Reference Figures 1 to 5 In one embodiment of the utility model, an embedded electromagnetic heating plate is proposed, including a heating plate body 1 and an electromagnetic coil 2. The heating plate body 1 is provided with two pieces opposite to each other. The heating plate body 1 is provided with a central hole 11. A plurality of wire clamping grooves 12 are provided between two adjacent heating plate bodies 1. The plurality of wire clamping grooves 12 are provided in the heating plate body 1 at intervals in the circumferential direction and are arranged around the central hole 11. A reinforcing rib 13 is passed through the heating plate body 1. The reinforcing rib 13 is passed through between two adjacent wire clamping grooves 12. The electromagnetic coil 2 is passed through the wire clamping groove 12. The electromagnetic coil 2 is connected to a power source. The electromagnetic coil 2 is provided with a plurality of groups. Each group of electromagnetic coils 2 corresponds to a wire clamping groove 12. The electromagnetic coil 2 includes a plurality of turns of wire 3 gathered together.

The adjustment straight line segment 322 is passed through the adjustment groove 16.
[0027] In an embedded electromagnetic heating plate of the present application, as Figure 1As shown, two groups of heating plate bodies 1 are arranged opposite to each other, and an electromagnetic coil 2 is sandwiched between the two groups of heating plate bodies 1. One heating plate body 1 is a coil embedding sheet, and the other is a magnetic cover plate, so that the electromagnetic coil 2 is in the two heating plate bodies 1, and both sides are heated by electromagnetic induction, which can protect and cover the electromagnetic coil 2, and at the same time play the role of overall heat conduction and pressure bearing. The mold or product that needs to be heated is usually placed on the magnetic cover plate. The electromagnetic coil 2 can be completely enclosed by sandwiching the electromagnetic coil 2 between the two heating plate bodies 1. The two heating plate bodies 1 can effectively absorb electromagnetic radiation, prevent electromagnetic leakage, and play the role of radiation protection and energy saving. In order to enable the electromagnetic heating plate to be used for stably heating the tire mold, the positive projection of the heating plate body 1 is circular, and the center hole 11 is also circular. Under such a structure, the heating plate itself is a circular ring. Because the electromagnetic coil 2 is distributed in the heating plate body 1, the circular ring structure allows the uniformly distributed electromagnetic coil 2 to be in the shape of a fan ring. This structure is more regular, so that the heating efficiency of the heating plate body 1 can be higher, and the electromagnetic coil 2 with a regular shape can more stably heat the heating plate body 1. Of course, the shape of the center hole 11 itself can also be rectangular or triangular, so the shape of the electromagnetic coil 2 also needs to be adjusted accordingly. The adjustment standard is to ensure that the interval between the center lines of the electromagnetic coil 2 is as consistent as possible. Only uniform wiring can stabilize the heating efficiency of the electromagnetic coil 2. The heating plate body 1 can also be designed as a rectangle, square or other special shape according to the shape of the heated body, and the center hole 11 is not provided in the center. Similarly, a wire clamping groove 12 is provided between the two heating plate bodies 1, and the electromagnetic coil 2 is arranged in the wire clamping groove 12. Through the tightly arranged coils, the heating plate body 1 can also be made to heat uniformly and stably.
[0028] Furthermore, a wire clamping groove 12 is provided in the heating plate body 1, and the wire clamping groove 12 is located inside the heating plate body 1, so that when the electromagnetic coil 2 is installed in the wire clamping groove 12, it can be completely surrounded by the heating plate body 1, so that electromagnetic induction can be generated on both the upper and lower sides of the heating plate, thereby avoiding magnetic field leakage and wasting a large amount of electromagnetic energy. A plurality of wire clamping grooves 12 are provided, and the plurality of wire clamping grooves 12 are evenly spaced and provided in the heating plate body 1, and an adjustment groove 16 is provided in the heating plate body 1 facing the electromagnetic coil 2, and the adjustment straight line segment 322 of the connecting unit is passed through the adjustment groove 16, and the second arc segment 321 of the wire , the third arc segment 323, the connecting end 33 and the connecting end tail 34 are all connected to the adjusting slot 16, and the connecting end 33 and the connecting end tail 34 can be connected to the corresponding high-frequency power supply through the adjusting slot 16.

Through the design of the adjusting slot 16, the power adjustment capability of the electromagnetic heating plate is more convenient and sensitive, which can effectively improve the power generation efficiency. The reinforcing rib 13 is provided between two adjacent wire slots 12, and the reinforcing rib 13 is used to strengthen the overall structure of the heating plate body 1. The force given to the heating plate body 1 by the heating element will be borne by the heating plate body 1 and the reinforcing rib 13, and will not affect the work of the electromagnetic coil 2. The reinforcing rib 13 is provided with a mounting hole 14 in the direction away from the heating plate body 1, and the mounting hole 14 can make the entire electromagnetic heating plate easy to install. A temperature sensor 15 is provided in the heating plate body 1, and the temperature sensor 15 can monitor the temperature of the heating plate in real time and feed back the temperature data to the heating plate The electromagnetic controller of the main body 1 can adjust the current frequency and amplitude of the electromagnetic coil 2 according to the temperature data to maintain the stability of the temperature of the heating plate or the mold. In this embodiment, in order to facilitate the installation of the temperature sensor 15, a long hole begins to be provided at the side edge of the heating plate main body 1 toward the center hole 11, and the temperature sensor 15 itself is a probe structure. The temperature sensor 15 can be conveniently installed through the long hole. In addition, in this embodiment, four groups of reinforcing ribs 13 are equidistantly arranged in the circumferential direction. The reinforcing ribs 13 and the heating plate main body 1 are wrapped around the electromagnetic coil 2, which can effectively protect the overall structure of the electromagnetic coil 2.
[0029] Furthermore, the electromagnetic coil 2 is composed of multiple turns of wire 3 bundled together, and the wire 3 itself is spirally wound from the outer edge of the wire clamping groove 12 to the center of the wire clamping groove 12 to form the electromagnetic coil 2.

Multiple groups of electromagnetic coils 2 can be connected in series to a group of high-frequency power supplies, or each group of electromagnetic coils 2 can be configured with a group of high-frequency power supplies. By controlling the current intensity of the power supply and adjusting the number of turns by adjusting the groove 16 in conjunction with the adjusting straight line segment 322, the heating power of the heating plate body 1 can be adjusted more accurately, so that the product heats more uniformly and stably.
