[0047] To make the above and other objects, features and advantages of the present application more comprehensible, a preferred embodiment of the present application will be described in detail as follows with reference to the drawings. In addition, the same reference numerals are used to indicate the same components throughout the drawings.

[0048] Please refer to Figure 1 Fig. 1 shows a first embodiment of the workpiece heating module of the present application, which comprises a mold set 1, a lifting device 2 and a heating module 3. The lifting device 2 allows the mold set 1 to move vertically so that the heating module 3 can heat the workpiece in the mold set 1.

[0049] In detail, the mold set 1 can have an upper mold 11 and a lower mold 12. The upper mold 11 and the lower mold 12 can be combined to form a mold cavity. Further, the upper mold 11 can have an upper mold core 11a, and the lower mold 12 can have a lower mold core 12a. The upper mold core 11a and the lower mold core 12a can jointly form a predetermined mold to shape a workpiece into a predetermined shape. In this embodiment, the lower mold 12 can be fixed to a carrier 13 by clamping, locking or engaging, etc. When the upper mold 11 and the lower mold 12 are separated, the lower mold 12 can be stably fixed without displacement or shaking.

[0050] The lifting device 2 is used to separate the upper mold 11 and the lower mold 12. For example, the lifting device 2 can directly or indirectly lift the upper mold 11 or lower the lower mold 12 to separate the upper mold 11 and the lower mold 12. In this embodiment, the lifting device 2 can have a plurality of lifting arms 21 which can be displaced by a driving device 22. For example, the driving device 22 can be a hydraulic or oil pressure push rod which can displace the plurality of lifting arms 21 in a closing direction D1 of the upper mold 11 and the lower mold 12. For example, the plurality of lifting arms 21 can be extended from the opening 13a of the platform 13 so that the plurality of lifting arms 21 can be adjacent to the mold set 1. The upper mold 11 can have a plurality of supporting members 14 which can be aligned with the plurality of lifting arms 21 in the closing direction D1. Preferably, one end of each of the plurality of lifting arms 21 can have a bracket 23 which can have a groove corresponding to the shape of the supporting member 14. In this way, each of the plurality of lifting arms 21 can be stably supported on each of the plurality of supporting members 14. Thus, each of the plurality of lifting arms 21 can be supported on each of the plurality of supporting members 14, and the upper mold 11 can be pushed away from the lower mold 12 in the closing direction D1 by the driving device 22. Preferably, the distance between the upper mold 11 and the lower mold 12 can be 10-20 cm, and the lower mold core 12a of the lower mold 12 can be exposed so that a worker can place a workpiece W on the lower mold core 12a for subsequent operations.

[0051] The heating module 3 has a heating member 31 which can be, for example, an infrared heating device or a high-frequency heating device. A heating portion 31a of the heating member 31 can be located on the lower mold core 12a to heat the workpiece W placed on the lower mold core 12a. In this embodiment, the heating member 3 can have a top plate 32 which can be combined with one end of a ring wall 33. The top plate 32 and the ring wall 33 can jointly form a space S, and the other end of the ring wall 33 forms an opening 34. The heating portion 31a can be a plurality of high-frequency coils located in the space S. In this way, the top plate 32 and the ring wall 33 can prevent heat loss of the heating portion 31a, thereby improving the overall heating efficiency.

[0052] The heating module 3 has a displacement module 35 which can drive the heating member 31 to displace between the upper die 11 and the lower die 12. Further, the displacement module 35 can have a driving member 351 which is displaceably combined with a track 352, the driving member 351 can be a connecting rod or a mechanical arm for example, and the driving member 351 can be connected with the heating member 31 by locking, clamping or integrally forming. The setting position or the extending direction of the track 352 can be adjusted by the worker, so that the heating member 31 can displace between the upper die 11 and the lower die 12, which is not limited in the utility model. In the embodiment, the extending direction D2 of the track 352 can be perpendicular to the closing direction D1 of the upper die 11 and the lower die 12. In this way, the driving member 351 of the displacement module 35 can drive the heating member 31 to displace between the upper die 11 and the lower die 12, so that the heating part 31a can heat the workpiece W located on the lower die core 12a, so as to heat the workpiece W.

[0053] In summary, the workpiece heating module of the utility model can separate the upper die and the lower die by the lifting device, and then the worker can place the workpiece on the lower die core of the lower die, and then the displacement module drives the heating member to displace between the upper die and the lower die, so as to heat the workpiece. In the automatic production process, the automatic hot pressing operation can be formed, and the demand for manual operation can be reduced, so as to save the labor cost and improve the production operation efficiency.

[0054] Although the utility model has been disclosed by the above preferred embodiments, it is not intended to limit the utility model, and any person skilled in the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the utility model, which still belongs to the technical scope protected by the utility model. Therefore, the protection scope of the utility model should include the meaning recorded in the appended claims and all changes within the equivalent scope.
