[0021] like Figure 1-3 As shown, a digital printing mold of a preferred embodiment of the utility model comprises a supporting surface 1 and an abutting surface 2 arranged opposite to each other, wherein the supporting surface 1 is used to support the inner surface of the bottom shell of the mobile phone case and is completely matched with the inner surface of the bottom shell, and a positioning hole 3 is provided on the abutting surface 2, and the positioning hole 3 is used to cooperate with the positioning pin on the transfer platform of the printing machine, and the supporting surface 1 is connected to the abutting surface 2 through a connecting surface 8. After the mobile phone case is installed, the side shell of the mobile phone case abuts against the connecting surface 8, and in order to avoid damage to the side shell of the mobile phone case, the connecting surface 8 is in an arc shape.

[0022] The digital printing mold based on the above technical features is provided with a relative supporting surface 1 and abutting surface 2, and a positioning hole 3 matched with the positioning pin is provided on the abutting surface 2. When printing is required, the mobile phone case is first put on the mold, and then the positioning hole 3 is put on the positioning pin, so that the abutting surface 2 abuts against the transfer platform, that is, the positioning installation of the mobile phone case on the transfer platform is realized. Since the supporting surface 1 is used to support the inner surface of the bottom shell of the mobile phone case and is fully adapted to the inner surface of the bottom shell, the mold fully supports the transfer surface of the mobile phone case when the silicone roller is pressed down for transfer, thereby avoiding deformation and displacement of the mobile phone case during the printing process and ensuring the printing effect.

[0023] In this embodiment, a groove extending toward the supporting surface is provided on the abutting surface 2, a positioning column 4 is provided in the groove, and the positioning hole 3 is provided on the positioning column 4. By providing the groove, the overall weight of the mold can be reduced, raw materials can be reduced, and costs can be saved. However, it is also necessary to ensure the overall strength of the positioning column 4 and the mold, so a first reinforcing rib 5 is connected between the side wall of the positioning column 4 and the inner wall of the groove. In order to accurately position, there are multiple positioning columns 4, and the multiple positioning columns 4 are evenly distributed along the length direction of the groove, and a second reinforcing rib 6 is connected between two adjacent positioning columns 4. Under the action of the first reinforcing rib 5 and the second reinforcing rib 6, the overall strength of the mold can be effectively guaranteed.

[0026] In this embodiment, grooves are provided at the four corners of the mold, which can not only reduce the total weight of the mold, but also improve the overall strength of the mold. During production, the positioning holes 3 of various mobile phone case molds have the same size, and the grooves at the four corners extend outward according to the size of the mobile phone case.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
