[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting, and stamping. In order to ensure that the mould has good mechanical properties and surface strength, it is necessary to heat treat the mould during the production and processing of the mould.

[0003] After searching, the patent with announcement number CN216585108U discloses a high-efficiency mold heat treatment furnace, which can make the mold rotate slowly in the furnace to achieve the effect of uniform heating, and effectively support the mold, effectively preventing the mold from hitting the furnace wall when rotating in the furnace and causing damage to the internal heating wire.

[0004] Although the above scheme can achieve the purpose of uniform heating by driving the mold to rotate in the furnace, it only has a placement plate for placing the mold. When multiple small molds are placed on the placement plate, since each mold rotates with the drive shaft as the center of the circle, and the heating wire is distributed on the inner wall of the heating box, no matter how the mold rotates driven by the placement plate, one part of it will always be close to the heating wire, while the other part will always be away from the heating wire. Therefore, it is difficult to ensure uniform heating of the small molds, which needs to be improved. Utility Model Content
