The second pressing member 20 is disposed above the first pressing member 10, and the pressing block 23 is fixed to a third surface 21 of the second pressing member 20, i.e., a lower surface of the second pressing member 20. When the first press-fitting member 10 and the second press-fitting member 20 are aligned and press-fitted with the heat-set product 200, the pressing block 23 downwardly abuts against the movable block 13. In this embodiment, four movable blocks 13 and four pressing blocks 23 are respectively disposed at four corners of the first pressing member 10 and the second pressing member 20, and the product 200 for thermal shaping may be rectangular and the four corners thereof may be respectively supported by the movable blocks 13. The product 200 includes, but is not limited to, alloys such as magnesium alloys, aluminum alloys, or metallic materials.

The thermal shaping jig 100 of the present embodiment can be installed on a thermal shaping machine (not shown in the figure), wherein the first pressing member 10 is disposed on a base (not shown in the figure) of the thermal shaping machine, and the second pressing member 20 is driven by a robot arm (not shown in the figure) to press against the first pressing member 10. The thermal shaping machine includes a heating device (not shown in the figure) for heating the first pressing member 10 and the second pressing member 20, so as to heat the product 200 to thermally shape the product 200.

Referring to fig. 3, the first pressing member 10 includes a first mold plate 15 and a pad block 16, the movable block 13 is disposed on a periphery of the first mold plate 15, the pad block 16 is disposed on the first mold plate 15, the pad block 16 is used for thermally shaping a fifth surface 210 of the product 200, and the fifth surface 210 of the product 200 is a lower surface in the first direction. In use, an external heat source conducts heat to the product 200 through the first template 15 and the mat blocks 16 to provide the thermal energy required for thermal shaping.

Referring to fig. 5, in an embodiment, the second pressing member 20 includes a second mold plate 24 and a pressing block 25, the pressing block 25 is connected to the second mold plate 24, the pressing block 25 is used for thermally shaping a sixth surface 220 of the product 200, and the sixth surface 220 is an upper surface of the product 200 in the first direction (i.e., the direction indicated by the arrow a in fig. 5). An external heat source conducts heat to the product 200 through the second die plate 24 and the swaging block 25 to provide the heat energy required for heat shaping.

In the using process, the four corners of the rectangular product 200 are placed on the movable blocks 13 respectively, then the first pressing piece 10 is pressed onto the second pressing piece 20, the four pressing blocks 23 apply acting force to the four movable blocks 13 downwards respectively, and the product 200 moves downwards along with the movable blocks 13 until the product 200 is attached to the first pressing piece 10. The first press-fitting member 10 includes a pad block 16, and the second press-fitting member 20 includes a press-fitting block 25, and when the movable block 13 is moved downward to the limit position, the pad block 16 and the press-fitting block 25 just hold the product 200 to thermally shape the product 200.
