[0020] In the embodiment, the number of the first slider 41 and the second slider 42 is two respectively, and the cavity 3 is located between the two first sliders 41 and the two second sliders 42, and the two first sliders 41 are located on the two sides of the cavity 3 respectively, and the two second sliders 42 are located on the other two sides of the cavity 3 respectively.
[0021] That is, for the shell product 6 provided with the buckle 7, it is usually a cuboid, and the four sides are all provided with the buckle 7. Therefore, the utility model surrounds the cavity 3 by the two first sliders 41 and the two second sliders 42, and forms the buckle 7 by the corresponding first insert 43 / second insert 44, so as to realize the one-time forming of the shell product 6.
[0022] Specifically, the number of the cavity 3 is n, and the n cavities 3 are located between the two first sliders 41 and the two second sliders 42, the first slider 41 is provided with kn first inserts 43 corresponding to the n cavities 3, and the second slider 42 is provided with ln second inserts 44.
