[0031] In the embodiment, by designing the skin positioning device 4, the skin positioning rod 42 is used for positioning and pressing the skin 3 during the lowering process of the upper mold 1, so that the skin 3 is in contact with the edge covering block 2, the problem that the skin 3 is scalded due to the fact that the skin 3 is deformed and the skin 3 is too close to the air outlet or even directly contacts the air outlet is avoided, and the skin 3 is scalded; by arranging the torsional spring 45, the skin positioning rod 42 can rotate around the torsional spring 45, and the skin positioning rod 42 can be reset during the upward movement of the upper mold 1; by arranging the limiting rod 43, the rotation angle of the skin positioning rod 42 can be limited, and the limiting rod 43 is connected with the support through the telescopic piece, so that the skin positioning rod 42 is prevented from being injured with the edge covering block 2 and the skin 3 during the lowering process of the upper mold 1.

[0032] Specifically,

[0033] As Figures 2-3 shown in the above embodiment, preferably, the telescopic piece is a spring telescopic rod 44; the two spring telescopic rods 44 are symmetrically installed on the two sides of the support 41 along the vertical direction, and the bottom ends of the two spring telescopic rods 44 extend out of the bottom end of the support 41 by a distance; the limiting rod 43 is transversely arranged between the bottom ends of the two spring telescopic rods 44 and is fixedly connected with the bottom ends of the spring telescopic rods 44. In the embodiment, the limiting rod 43 and the spring telescopic rods 44 on the two sides jointly form a U-shaped structure, and the U-shaped structure can effectively limit the freedom degree of the downward rotation of the skin positioning rod 42.

[0034] In the above embodiment, preferably, a spring is arranged in the spring telescopic rod 44, and the spring telescopic rod can be extended and retracted through the compression of the spring.

[0035] In the above embodiment, preferably, when the upper mold 1 continues to descend, the skin positioning rod 42 rotates through the torsion spring 45 to avoid damaging the skin 3 and the edge block 2.

[0036] like Figures 4-6 As shown, the usage method of this embodiment is as follows:

[0037] 1) In the initial state, the free end of the skin positioning rod 42 faces downward and is limited by the limiting rod 43;

[0038] 2) When the upper mold 1 descends, it drives the skin positioning rod 42 to descend downwards. At this time, the free end of the skin positioning rod 42 contacts the skin 3, such as... Figure 4 As shown;

[0039] 3) As the upper mold 1 continues to descend, the skin positioning rod 42 will press the skin 3 downwards until the skin 3 contacts the edge-sealing block 2, such as Figure 5 As shown;

[0040] 4) At this point, if the upper mold 1 continues to descend, the skin positioning rod 42 rotates upward under the action of the torsion spring 45, thereby ensuring the positioning of the skin 3 while preventing the skin positioning rod 42 from damaging the skin 3 and the edge-sealing block 2. Figure 6 As shown.

[0041] like Figure 7 As shown, in the above embodiment, preferably, to improve versatility and prevent the limiting rod 43 from damaging the edge-binding block 2, when the upper mold 1 continues to descend and the limiting rod 43 contacts the edge-binding block 2, the limiting rod 43 will compress the spring inside the spring telescopic rod 44, so that the spring telescopic rod 44 drives the limiting rod 43 to retract, achieving soft contact between the limiting rod 43 and the edge-binding block 2.

[0042] like Figure 8 As shown, in the above embodiment, preferably, when the upper mold 1 rises, the limiting rod 43 pops out under the action of the spring inside the spring telescopic rod 44 to return to its original position so as to correctly limit the skin positioning rod 42.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
