[0050] As Figure 6 In the present embodiment, the printing plate 1 is detachably connected and fixed with the printing substrate 2 by the locking member 4, and the shoe mold 23 is printed on the printing substrate 2, and the shoe mold 23 is directly 3D printed on the printing substrate 2, so that the shoe mold 23 does not need to be cut off from the printing plate 1, and a process of cutting the shoe mold 23 from the printing plate 1 (generally linear cutting) is saved, and a process of preparing the printing plate 1 again (generally milling) is also saved.

[0051] In the present embodiment, the printing plate 1 has a mounting surface 11 for mounting the printing substrate 2, and a plurality of locking members 4 are arranged in an array in the mounting surface 11 to adapt to the fixation of printing substrates 2 of different sizes.

[0052] As Figure 9, the locking member 4 comprises a plurality of waist-shaped holes 41 and a plurality of connecting screws 42 arranged on the printing plate 1; the plurality of waist-shaped holes 41 are arranged in an array; the connecting screw 42 has a rotating nut, and the connecting screw 42 is clamped or released on both sides of the waist-shaped hole 41 by rotating the nut, so as to fix or remove the connection between the printing plate 1 and the printing substrate 2.

[0053] As Figure 8 , the clamping of the locking member 4 is formed by the connecting screw 42 penetrating the waist-shaped hole 41 of the printing plate 1 and the printing substrate 2 in sequence, and by rotating the nut to drive the connecting screw 42 to press against the printing substrate 2 and at the same time to be resisted by the nut at both end faces of the waist-shaped hole 41 to form a clamping and fixing by friction force, and the clamping and fixing by friction force can be released by reverse rotation. The connection between the connecting screw 42 and the printing plate 1 can ensure that the deformation of the printing plate 1 is within the allowable range.

[0054] In the embodiment, the number of the waist-shaped holes 41 is set to 30, and the distribution of the number, the spacing of each waist-shaped hole 41 and the size of the waist-shaped hole 41 itself are adapted to printing all shoe size of men's, women's and children's shoes.

[0055] Further, the waist-shaped hole 41 is designed as a through hole with a semicircular arc at both ends and a parallel plane in the middle, and the displacement amount of the connecting screw 42 is formed by the spacing distance between the two semicircular arcs, and in the released clamping state, the connecting screw 42 can move left and right in the waist-shaped hole 41 to adjust the installation position of the printing substrate 2, and the displacement amount includes the movement amount of fine adjustment between similar shoe sizes, which can ensure that the printing plate 1 can adapt to different sizes of the printing substrate 2.

[0056] In the embodiment, preferably, the waist-shaped holes 41 are arranged in two rows along the wide edge of the printing plate 1, forming the connection and fixation of the printing substrate 2 on both sides, further fixing the printing substrate 2 on the printing plate 1 and keeping the stability of the printing substrate 2, while ensuring that the deformation of the printing plate 1 is within the allowable range.

[0057] As Figure 10 -11, preferably, the side of the printing plate 1 away from the mounting surface 11 is recessed to form a stepped surface 12 at the positions corresponding to the waist-shaped holes 41; the stepped surface 12 and the end face of the side of the printing plate 1 away from the mounting surface 11 form a height difference for accommodating the nut, and in the clamping state, the nut is resisted on the stepped surface 12, and the arrangement of the stepped surface 12 can ensure the flatness of the end face of the side of the printing plate 1 away from the mounting surface 11, and when the printing plate 1 is installed at the position of the 3D printer, the printing plate 1 can be stably installed at the specified position of the 3D printer for printing. At the same time, the stepped surface 12 can also satisfy the connection and fixation structure of the waist-shaped hole 41 and the connecting screw 42.

[0058] In the embodiment, the printing plate 1 is installed with the 3D printer, mainly by the printing plate fixing hole 14 and the fixing bolt installed and fixed on the printing plate 1.

[0059] As Figure 12 In the embodiment, the shoe mold frame 3 has a shoe mold positioning hole 31 for assembling with the printed substrate 2 after printing the shoe mold 23; the shoe mold frame 3 has different sizes of shoe mold positioning holes 31 to adapt to different shoe sizes of the shoe mold 23. The shoe mold frame 3 used in the embodiment is different from the shoe mold frame 3 used in the traditional 3D printing shoe mold 23 method. The shoe mold positioning hole 31 in the embodiment is hollow and bottomless, which can be processed by CNC or wire cutting.

[0060] As Figure 13 Further, the shoe mold frame 3 is assembled with the printed substrate 2 by a fastener to be detachably connected and fixed, the shoe mold frame 3 includes a fastening screw hole 33 arranged on four sides, and the fastener is a fastening screw to realize the detachable connection and fixation of the shoe mold frame 3 and the printed substrate 2 by screw spiral locking.

[0061] In order to better implement the technical solution of the embodiment, in the embodiment, positioning devices are arranged between the installation of the printed substrate 2 and the printing plate 1 and the assembly of the printed substrate 2 and the shoe mold frame 3, which facilitates the positioning adjustment of the two before installation.

[0062] As Figure 7 Further, the installation and positioning of the printed substrate 2 and the printing plate 1 are as follows: a first positioning pin 21 is arranged on one end surface of the printed substrate 2 and the printing plate 1 during installation, and a first positioning hole 13 is arranged on the installation surface 11 of the printing plate 1 to adapt to the first positioning pin 21; the first positioning pin 21 and the first positioning hole 13 cooperate to position the printed substrate 2 during installation.

[0063] The assembly and positioning of the printed substrate 2 and the shoe mold frame 3 are as follows: a second positioning pin 22 is arranged on one surface of the printed substrate 2 and the shoe mold frame 3 during assembly, and a second positioning hole 32 is arranged on the shoe mold frame 3 to adapt to the second positioning pin 22; the second positioning pin 22 and the second positioning hole 32 cooperate to position the shoe mold frame 3 during assembly.

[0064] A 3D printing shoe mold 23 printing method using a 3D printing shoe mold 23 mold, the printing method is as follows:

[0065] Step 1, when starting 3d printing shoe mold 23, select the appropriate shoe size of the printing substrate 2, first fix the printing substrate 2 on the printing plate 1. The printing substrate 2 is positioned by the positioning pin on the printing plate 1, and after adjusting the connection position with the printing plate 1, it is locked on the printing plate 1 by the connecting screw 42;

[0066] Step 2, after fixing the printing substrate 2, model the 3D printing shoe mold 23 on the printing plate 1 substrate to form the shoe mold 23-substrate assembly; after 3d printing is completed, loosen the fastening screw, and take down the shoe mold 23-substrate assembly;

[0067] Step 3, finally, assemble the shoe mold frame 3 on the shoe mold 23-substrate assembly to form a complete shoe mold 23 lower mold, and perform 3D printing of the sole forming mold.

[0068] The above method of 3d printing shoe mold 23, compared with the traditional method of 3d printing shoe mold 23, saves a process of cutting the shoe mold 23 from the printing plate 1 (usually line cutting), and saves the process of preparing the printing plate 1 again (usually milling). At the same time, the shoe mold positioning hole 31 of the shoe mold frame 3 can be machined by milling or line cutting. In the traditional 3d printing method, due to the existence of the metal at the bottom of the shoe mold positioning hole 31, only milling can be used. Therefore, this method improves the work efficiency and reduces the cost.

[0069] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
