Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 4As shown, a heating device for an aluminum trim molding mold comprises a heating furnace body 1, an insulation layer 2 and a mold body 3, wherein the insulation layer 2 is embedded in the interior of the heating furnace body 1, and the insulation layer 2 is used to insulate the internal temperature of the heating furnace body 1, and the mold body 3 is arranged in the insulation layer 2.

The rotating shaft 62 is arranged at the end of the driving motor 61. The rotating shaft 62 is rotatably connected to the heating furnace body 1 and the insulation layer 2. The rotating shaft 62 and the driving motor 61 are connected through a coupling, so that the driving motor 61 can drive the rotating shaft 62 to rotate when it is started. A connecting rod 63 is welded on the cylindrical surface of the rotating shaft 62 and is located near the inner wall of the insulation layer 2. The bottom ends of the two connecting rods 63 are connected to each other. A placing platform 64 is arranged between the two sides of the placing platform 64, and connecting shafts 65 are welded on both sides of the placing platform 64. The connecting shaft 65 is located inside one end of the connecting rod 63. The placing platform 64 rotates synchronously with the rotating shaft 62. The mold body 3 is arranged on the surface of the placing platform 64. The placing platform 64 is used to place the mold body 3. When the rotating shaft 62 is located inside the heat preservation layer 2 and rotates, the connecting rod 63 welded on the rotating shaft 62 can rotate together. At this time, the placing platform 64 between the two connecting rods 63 rotates with the two connecting rods 63, and the mold body 3 located on the placing platform 64 also rotates with the rotating shaft 62. When the mold body 3 is heated, the mold body 3 is heated more evenly. Two fixing rods 66 are welded to the edge of the placement platform 64. The ends of the two fixing rods 66 are provided with clamping plates 67. The clamping plates 67 are threadedly connected to the ends of the fixing rods 66. The two clamping plates 67 are both located on the surface of the mold body 3. The clamping plates 67 are used to limit the mold body 3 on the placement platform 64. The mold body 3 can be placed on the placement platform 64, and the clamping plates 67 can be rotated around the fixing rods 66 so that the clamping plates 67 clamp the surface of the mold body 3, so that the two clamping plates 67 can limit the mold body 3 at the fixing rods 66.

[0034] See also Figure 3 and Figure 4As shown, the rotating shaft 62 passes through the interior of the heating furnace body 1 and the insulation layer 2, and bearings are arranged at both ends of the rotating shaft 62. The rotation range radius of the mold body 3 is smaller than the inner cavity space size of the insulation layer 2. The bearings are installed inside the heating furnace body 1, and the rotating shaft 62 is located inside the bearings, so that the driving motor 61 can start to rotate the rotating shaft 62, and when the mold body 3 rotates around the rotating shaft 62, the mold body 3 will not interfere with the interior of the insulation layer 2.

[0035] See also Figure 4 As shown, the height of the fixing rod 66 is greater than the thickness of the mold body 3, and the edge of the clamping plate 67 is provided with a chamfered angle, so that the clamping plate 67 can smoothly enter the surface of the mold body 3 when rotating, and the lower surface of the clamping plate 67 is slidably connected to the upper surface of the mold body 3, and the clamping plate 67 can be rotated around the fixing rod 66, so that the clamping plate 67 is attached to the surface of the mold body 3, thereby tightly attaching the clamping plate 67 to the placement platform 64 to prevent the mold body 3 from falling from the placement platform 64.

[0036] It should be noted that when the aluminum trim strip forming mold is processed by machining, it is necessary to perform heat treatment on the aluminum trim strip forming mold in a heating furnace to ensure that the aluminum trim strip forming mold meets the requirements when used later. When performing heat treatment, the mold body 3 is placed inside the furnace body 1 of the heating furnace. Specifically, the clamping plate 67 is rotated around the fixing rod 66, so that the two clamping plates 67 are moved away from above the placement platform 64, and the mold body 3 can be placed on the surface of the placement platform 64. Then the clamping plate 67 is rotated to press the clamping plate 67 against the surface of the mold body 3. The chamfered edge of the clamping plate 67 can facilitate the clamping The tightening plate 67 smoothly enters the surface of the mold body 3. After the mold body 3 is fixed, the driving motor 61 can be started. The driving motor 61 drives the rotating shaft 62 to rotate. The rotating shaft 62 and the connecting rod 63 welded on the rotating shaft 62 rotate. The two connecting rods 63 can rotate the placement platform 64, so that the cavity groove 4 on the placement platform 64 can rotate. When the heating furnace body 1 is preliminarily heated, the mold body 3 can be heated more evenly. When the mold body 3 rotates, the fixing rod 66 and the clamping plate 67 can limit the mold body 3 on the placement platform 64 to prevent the mold body 3 from falling from the placement platform 64.

[0043] It should be noted that when the connecting rod 63 drives the connecting shaft 65 to rotate around the rotating shaft 1 62, the spur gear 73 engages with the internal gear 72, and the connecting shaft 65 drives the spur gear 73 and the bevel gear 1 81 to rotate, thereby the bevel gear 1 81 and the bevel gear 2 82 rotate, the rotating platform 83 and the bevel gear teeth 84 of the rotating platform 83 rotate, and the rotating hole 86 of the rotating platform 83 rotates around the rotating shaft 2 85 of the placing platform 64, so that the placing platform 64 and the rotating platform 83 rotate relative to each other, and the mold body 3 can rotate around the axis of the rotating shaft 2 85.

The mold body 3 and the cavity block 5 can be matched with each other so that the mold body 3 and the cavity block 5 are completely consistent, thereby ensuring that the mold body 3 and the cavity block 5 of the same material are heated synchronously during heating to avoid the cavity groove 4 of the mold body 3 from being overheated. In addition, the mold body 3 and the cavity block 5 are made of the same material, so that the inner wall of the cavity groove 4 is heated evenly, and the cavity block 5 can also be taken out from the inside of the cavity groove 4.

The cavity block 5 can also be placed inside the cavity groove 4 of the die body 3 as needed, so that the die body 3 and the cavity block 5 are closed together. At this time, the heat inside the insulation layer 2 is heated to the inside of the die body 3 and the cavity block 5 to avoid excessive heat at the cavity groove 4 causing large deformation of the cavity groove 4 of the die body 3, which affects the later extrusion.
