[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0026] In a first aspect, this utility model embodiment provides a heating structure, referring to... Figure 1The heating structure includes a first metal component 1 and a second metal component 2, both of which have an electric heating element (not shown in the figure). Both the first metal component 1 and the second metal component 2 are in contact with the heated object (the object to be heated). An insulation layer (not shown in the figure) is provided on the side of the first metal component 1 and the second metal component 2 away from the heated object. The electric heating element converts electrical energy into heat energy. When the first metal component 1 and the second metal component 2 are assembled together, the electric heating element can be fixed to the heated object, and the heat generated by the electric heating element can be evenly transferred to the heated object. The first metal component 1 and the second metal component 2 are detachable and can rotate relative to each other. Multiple first metal components 1 and multiple second metal components 2 are provided, arranged alternately to fit circular, elliptical, or polygonal heated objects. Typically, multiple first metal components 1 and multiple second metal components 2 are assembled into a circle to fit a circular heated object (such as the circular sleeve at the injection end of an injection molding machine).

[0027] The electric heating assembly comprises multiple sets. In this embodiment, the preferred electric heating assembly consists of an electric heating wire and a circular quartz tube. The electric heating wire is inserted into the quartz tube and contacts the inner wall of the quartz tube. The electric heating wire is connected to a power source to convert electrical energy into heat energy, thereby heating the quartz tube. The quartz tube itself has high thermal conductivity, enabling rapid and uniform heat transfer; it also effectively isolates current, avoiding the risk of leakage; and the quartz tube can withstand temperatures above 1000 degrees Celsius. Multiple quartz tubes are inserted into corresponding first metal parts 1 and second metal parts 2. The electric heating wires between adjacent first metal parts 1 and second metal parts 2 are connected in series, meaning that the electric heating wires between adjacent first metal parts 1 and second metal parts 2 are formed by bending the same heating wire; this reduces the number of connection points of the electric heating wires and lowers energy loss.

[0028] Multiple first metal parts 1 have the same structure; multiple second metal parts 2 have the same structure. The following description will be based on the structure of one first metal part 1 and one second metal part 2.

[0029] Reference Figure 1 Both the first metal part 1 and the second metal part 2 are metal materials with good thermal conductivity. The first metal part 1 and the second metal part 2 can be made of aluminum; they can also be made of other metal materials such as copper, silver, and tungsten. In this embodiment, the first metal part 1 and the second metal part 2 are preferably made of aluminum, which results in good thermal conductivity, light weight, and low cost.

[0030] Reference Figure 1 and Figure 2A first mounting groove 11 is provided at one end of the first metal part 1, and the first mounting groove 11 extends through the first metal part 1 along the opening direction. Since the quartz tube is a round tube, the first mounting groove 11 is a round groove. After the quartz tube is inserted into the first mounting groove 11, the outer peripheral wall of the quartz tube contacts the inner peripheral wall of the first mounting groove 11, thereby enabling more uniform heat transfer to the first metal part 1 and timely response of the heating speed.

[0031] Assume the side of the first metal part 1 that contacts the heated body is the inner wall of the first metal part 1. The inner wall of the first metal part 1 has a first opening 12. The extension direction of the first opening 12 is consistent with the extension direction of the first mounting groove 11, and the first opening 12 and the first mounting groove 11 are connected to form a superior arc groove. In this way, the quartz tube is not easy to fall out of the first opening 12, and there is no obstruction on the side of the quartz tube close to the heated body, which allows some heat to be directly conducted to the heated body, reducing heat loss.

[0032] The first metal part 1 has two protrusions 13 integrally formed on the outer walls of both sides perpendicular to the first opening 12. Both protrusions 13 are located at the first opening 12 and are in contact with the heated body, thereby increasing the contact area between the first metal part 1 and the heated body and improving the heat conduction effect.

[0033] Reference Figure 1 and Figure 2 The first metal part 1 has two first protrusions 13, and on the outer walls of both sides, a first connecting protrusion 14 and a second connecting protrusion 15 are integrally formed. The first metal part 1 is assembled and connected to two adjacent second metal parts 2 through the first connecting protrusions 14 and the second connecting protrusions 15. The length of the first connecting protrusion 14 from the end away from the first metal part 1 to the corresponding side of the first metal part 1 is greater than the extension length of the first protrusion 13 on the corresponding side; the length of the second connecting protrusion 15 from the end away from the first metal part 1 to the corresponding side of the first metal part 1 is greater than the extension length of the first protrusion 13 on the corresponding side, so that the first connecting protrusions 14 and the second connecting protrusions 15 can be normally rotated and adjusted inward after being connected to the corresponding second metal parts, and also allow the first metal part 1 and the second metal part 2 to have a larger rotation adjustment angle.

[0034] Combination Figure 1 Reference Figure 2 and Figure 3 A second mounting groove 21 is provided at one end of the second metal part 2, and the second mounting groove 21 extends through the second metal part 2 along the opening direction. Since the quartz tube is a round tube, the second mounting groove 21 is a round groove. After the quartz tube is inserted into the second mounting groove 21, the outer peripheral wall of the quartz tube contacts the inner peripheral wall of the second mounting groove 21, thereby enabling more uniform heat transfer to the second metal part 2 and timely response of the heating speed.

[0035] The side of the second metal part 2 that contacts the heated body is the inner wall of the second metal part 2. The inner wall of the second metal part 2 has a second opening 22. The extension direction of the second opening 22 is consistent with the extension direction of the second mounting groove 21, and the second opening 22 and the second mounting groove 21 are connected to form a superior arc groove. In this way, the quartz tube is not easy to fall out of the second opening 22, and there is no obstruction on the side of the quartz tube close to the heated body, which allows some heat to be directly conducted to the heated body, reducing heat loss.

[0036] The second metal part 2 has two protrusions 23 integrally formed on the outer walls of both sides perpendicular to the second opening 22. Both protrusions 23 are located at the second opening 22 and are in contact with the heated body, thereby increasing the contact area between the second metal part 2 and the heated body and improving the heat conduction effect.

[0037] Combination Figure 1 Reference Figure 2 and Figure 3 The second metal part 2 has extension plates 24 integrally formed on both outer walls of the two second protrusions 23. The two extension plates 24 are respectively provided with a first connecting groove 25 and a second connecting groove 26. When the first metal part 1 is located on one side of the first connecting groove 25, the first connecting protrusion 14 is inserted into the first connecting groove 25 for assembly; when the first metal part 1 is located on one side of the second connecting groove 26, the second connecting protrusion is inserted into the second connecting groove 26 for assembly. The extension length of both extension plates 24 is greater than the extension length of the corresponding second protrusion 23, allowing the first metal part 1 and the second metal part 2 to rotate and adjust inwards normally after connection, accommodating circular heated bodies, and also allowing for a larger rotation adjustment angle for the first metal part 1 and the second metal part 2.

[0038] Combination Figure 1 Reference Figure 2 and Figure 3 Specifically, the first connecting protrusion 14 is integrally formed with a first rotating shaft 16, and the first connecting groove 25 is an arc groove adapted to the first rotating shaft 16. The first rotating shaft 16 is inserted into the first connecting groove 25. Under the action of the arc groove, the first rotating shaft 16 is not easily dislodged from the opening of the arc groove, and the first rotating shaft 16 can rotate within a certain angle range within the first connecting groove 25 to achieve adjustment. Similarly, the second connecting protrusion 15 is integrally formed with a second rotating shaft 17, and the second connecting groove 26 is an arc groove adapted to the second rotating shaft 17. The second rotating shaft 17 is inserted into the second connecting groove 26. Under the action of the arc groove, the second rotating shaft 17 is not easily dislodged from the opening of the arc groove, and the second rotating shaft 17 can rotate within a certain angle range within the second connecting groove 26 to achieve adjustment. This arrangement allows the first metal part 1 and the two adjacent second metal parts 2 to rotate freely for adjustment, enabling a closer fit with the arc-shaped heating body.

[0039] Combination Figure 1 Reference Figure 2 and Figure 3 In this configuration, the first connecting protrusion 14 and the second connecting protrusion 15 are spaced apart from their corresponding first protrusions 13; the two extension plates 24, the first connecting groove 25, and the second connecting groove 26 are spaced apart from their corresponding second protrusions 23. When heating a circular or elliptical heat-receiving body, after the first connecting protrusion 14 and the first connecting groove 25 are connected, the first protrusions 13 and 23 are in contact with the heat-receiving body, and the corresponding first protrusions 13 and 23 can abut against each other, forming a double-layer structure. This allows the first connecting protrusion 14 and the first connecting groove 25 to form a heat-insulating cavity 18 with the corresponding first protrusions 13 and 23, reducing heat loss. Similarly, after the second connecting protrusion 15 is connected to the second connecting groove 26, the corresponding first protrusions 13 and 23 abut against each other, also forming a heat-insulating cavity 18, reducing heat loss.

[0040] When heating a flat or uneven surface, the extension length of the first protrusion 13 or the second protrusion 23 can be controlled during production to ensure that after the first metal part 1 and the second metal part 2 are joined, the first protrusion 13 and the second protrusion 23 abut to form the heat-insulating cavity 18. Alternatively, when heating a flat surface, the first metal part 1 and the second metal part 2 can remain relatively fixed after connection without rotating.

[0041] Reference Figures 1 to 5 To make it easier for workers to distinguish between the first metal part 1 and the second metal part 2 during assembly, a distinguishing structure will be provided on either the first metal part 1 or the second metal part 2. This distinguishing structure can be a texture, color, finned plate 27, or a mark. Specifically, the outer surface of the first metal part 1 can be made smooth, while the outer surface of the second metal part 2 can have a textured surface; or the outer surfaces of the first metal part 1 and the second metal part 2 can be machined to different colors; or a finned plate 27 can be integrally machined onto the outer surface of either the first metal part 1 or the second metal part 2, while the other is not machined with a finned plate 27; or different marks can be written on the outer surfaces of the first metal part 1 and the second metal part 2 with a marker. In this embodiment, it is preferable to integrally form a finned plate 27 on the second metal part 2.

[0042] The implementation principle of a heating structure according to an embodiment of this application is as follows: When heating a circular heat-receiving body, multiple sets of electric heating components are respectively inserted into the first mounting groove 11 and the second mounting groove 21 of the first metal component 1 and the second metal component 2. During assembly, multiple first metal components 1 and second metal components 2 are arranged alternately, i.e., one first metal component 1, one second metal component 2, one first metal component 1, and one second metal component 2, and so on. When the first metal component 1 is connected to two second metal components 2 on adjacent sides, the first rotating shaft 16 is inserted into the first connecting groove 25 of the second metal component 2 on the corresponding side; the second rotating shaft 17 is inserted into the second connecting groove 26 of the second metal component 2 on the other side. Then, the angles of the first metal component 1 and the second metal component 2 are adjusted so that the inner wall and the first protrusion 13 of the first metal component, and the inner wall and the second protrusion 23 of the second metal component 2 are all in contact with the heat-receiving body; and the corresponding first protrusion 13 and the second protrusion 23 abut against each other to form a heat-insulating cavity 18. After multiple first metal parts 1 and second metal parts 2 are spliced ​​together and wrapped around the heated body, a high-temperature resistant insulation layer is wrapped around the outer surface of the first metal parts 1 and second metal parts 2 to reduce heat loss.

[0043] The first metal part 1 and the second metal part 2 are made of metal materials with good thermal conductivity. After the electric heating component heats the first metal part 1 and the second metal part 2, the first metal part 1 and the second metal part 2 can form a heating rod. The first metal part 1 and the second metal part 2 are in contact with the heated body, which reduces the conduction links and can transfer heat to the heated body in a timely manner.
