The electric heating tubes 311 of the two inner electric heating modules 设置 disposed in the inner portion 22 are driven by the corresponding pylons 41 to heat the inner portion 22 ′ of the heat conducting plate 2 and After the temperature feedback of the corresponding temperature sensors 51 is feedback, the corresponding control rectifiers 41 are controlled by the control unit 6, and the electric heating tubes 311 are driven to reach a third lower than the second preset temperature. Preset temperature. Since the heating temperature of the heat conduction plate 2 is gradually decreased from the outside to the inside, and the arrangement and heating temperature of the electric heating pipes 321 located in the outer portions 21 are symmetrically arranged, the heat conduction plate 2 is heated. The temperature is uniform, and the heating temperature on both sides of the heat conduction plate 2 is not different from the center due to the influence of the lower ambient temperature.

Group 31 each has three electric heating tubes 311. The number of the control rectifiers 41 and the temperature sensors 51 is seven, wherein the three control rectifiers 41 are electrically connected and drive the internal electric heating modules Μ M404990 The heating temperature (4) of the inner electric heating module 3ι located on both sides, and the heating temperature is a third preset temperature lower than the second preset temperature. The heating temperature of the central electric heating module 31 in the inner electric heating module 31 is a fourth preset temperature lower than the third preset temperature. Thus, the second preferred embodiment can achieve the same objects and effects as the first preferred embodiment described above. It is worth mentioning that when the three inner electric heating modules 31 are disposed in the inner portion 22, the number of electric heaters 311 and 321 may be not three, as long as each inner electric heating mold is located on both sides. The number of the electric heating pipes 311 and 321 in the group 31 and each of the outer electric heating modules h is the same, and the number of the electric heating pipes 3U located in the central inner electric heating module 31 is not greater than the number, and the same efficiency can be achieved. The heating temperature of the external electric heating module 32 that is symmetric with each other is greater than the internal electric heating module 3 by the control of the control unit 6, thereby ensuring uniform temperature distribution of the template 7 and improving the yield of the product. Therefore, the purpose of this new type can be achieved. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
