Specifically, the structural layer 8 may include an inner structural layer 1, an outer structural layer 3, and a heating layer 2, wherein the heating layer 2 is located between the inner structural layer 1 and the outer structural layer 3. Therefore, the heating function of the heating layer 2 is utilized to increase the temperature of the mold during use. The inner structure layer 1 and the outer structure layer 3 can be integrally formed by pouring, so that the integral quality of the inner structure layer 1 and the outer structure layer 3 is improved. The specific structure of the heating layer 2 may not be limited, for example, in some embodiments, the heating layer 2 may be heated by liquid. Specifically, when the heating layer 2 is heated by liquid, the heating layer 2 is a cavity filled with liquid. Wherein the liquid can flow in the cavity and has a certain temperature. Thus, heating of the mould is achieved by the flow of liquid within the cavity. Alternatively, in some embodiments, heating layer 2 may employ electrical heating. Specifically, an electric heating wire or an electric heating tube is arranged in the heating layer 2, and the heating of the mold is realized through the electric heating wire and the electric heating tube.
Referring to FIG. 1, in some embodiments, the insulation layer 10 may be provided as a multi-layer structure. Through the multilayer structure, the mold has a good heat preservation effect. Specifically, in one embodiment, the insulation layer 10 may include a bottom layer 4, a surface layer 6, and an insulation layer 5, wherein the insulation layer 5 is located between the bottom layer 4 and the surface layer 6. Wherein, bottom 4 bonds with outer structural layer 3 to guarantee to closely paste the laminating between bottom 4 and the outer structural layer 3, and then improve the heat preservation effect of heat preservation in the in-service use. Also, in one embodiment, the insulating layer 5 is bonded to the bottom layer 4 and the insulating layer 5 is bonded to the top layer 6. The bottom layer 4, the heat insulating layer 5 and the surface layer 6 are bonded to each other, so that the stability of connection among the bottom layer 4, the heat insulating layer 5 and the surface layer 6 is improved, and the actual heat insulating effect is improved. The specific materials of the bottom layer 4 and the surface layer 6 may not be limited, and in one embodiment, the bottom layer 4 and the surface layer 6 may be made of glass fiber reinforced plastic. The bottom layer 4 and the surface layer 6 are made of glass fiber reinforced plastic materials, so that the stability of the bottom layer 4 and the surface layer 6 in the actual use process is improved. The actual thickness of the bottom layer 4 and the surface layer 6 may not be limited, for example, the actual thickness of the bottom layer 4 and the surface layer 6 may be allowed to be 1-2 mm.

Specifically, the polishing mode may not be limited, and in some embodiments, for example, 40-mesh sand paper may be used for polishing.
Referring to fig. 1, in some embodiments, the thermal insulation layer 5 may be provided with a plurality of through holes 9, and the specific shape of the through holes 9 may not be limited. For example, the through holes 9 may be circular or polygonal, and in one embodiment, the through holes 9 are regular hexagons.

Particularly, the honeycomb structure has the advantages of light weight, high strength and difficult deformation, and can effectively reduce the thickness of the heat-insulating layer 10 of the die, thereby reducing the weight of the die. Therefore, the overall structural weight of the mold is reduced on the premise of ensuring the strength of the heat-insulating layer 10. Furthermore, in the using process of the die, the requirement on a turning system of the die is also continuously reduced, and the die cost is effectively reduced.

The edge sealing layer forms a closed space between the bottom layer 4 and the surface layer 6, so that the practical effect of the heat preservation layer 10 is improved. In one embodiment, the edge sealing layer may be made of a resin material. After the bonding between bottom 4, insulating layer 5 and top layer 6 is accomplished, still can be through the mode of whole extraction vacuum for heat preservation 10 solidification shaping, in order to improve heat preservation 10 intensity.
