The embossing plate 4 is attached to the front surface of the upper material 1; at the same time, the vacuum pump mechanism connected to the lower mold base 2 is no longer actuated to generate suction, so that the front surface of the upper material 1 can be adsorbed by the pattern stencil 4 to form a negative pressure plastic. Shape (the three-dimensional shape and texture of the surface of the pattern stencil is obtained by rubbing), and the second upper mold base 5 is actuated to lower the pattern stencil 4 downwardly to lower the mold base 2 (as shown in Fig. 7), so that the lower mold base 2 is opposite The back surface of the upper material 1 forms a positive pressure (ie, the surface of the pattern stencil is convex), whereby the strength of the positive and negative pressure is applied to the upper material 1 to make the three-dimensional shape and texture on the pattern stencil 4, and the proper embossing ( The rubbing is obtained on the upper material 1.

The above step of obtaining the finished product S16; referring to Fig. 8, the second upper mold base 5 stops adsorbing the upper material 1, and blows the upper material 1 by a gas to fall into the concave chamber of the lower mold 2 21, and remove the second upper mold base 5 is no longer pressed against the upper material 1 and the lower mold base 2, so that the user can obtain the plasticized finished upper material 1 from the concave chamber 21 of the lower mold base 2 . In one embodiment, by suspending the vacuum pump mechanism connected to the second upper mold base, the air compressor is operated to supply a gas pressure from the blow hole, and the groove 511 is passed through the pattern stencil 4 to the surface of the pattern stencil 4, and The upper material 1 forms a thrust to move the upper material 1 into the recess 21 of the lower mold base 2.

According to the above steps, the upper of the shoe produced according to the present invention is integrated into one. In addition to saving the process and material loss of each shoe spare parts preparation, the process of sewing and the like can be omitted; further, since the upper of the invention is integrally formed, it has a process corresponding to the sewing combination. Better structural strength and ease of production.

Please refer to FIGS. 5 and 9 for the manufacturing method of the above-mentioned pattern stencil 4 of the present invention, which comprises the production of S21 first 矽 rubber relief printing S22, the first 矽 rubber relief splicing S23, and the epoxy resin gravure production. Steps S24, second rubber relief printing S25, and pattern stencil forming S26 are performed to obtain the texture of the surface of the upper-like plate (for example, the upper 9 shown in Fig. 10), and a pattern 4 having a breathable pattern is provided.

The above-mentioned ruthenium rubber gravure preparation step S21; taking a silicone rubber SI (Silicone Rubber) coating material coated on the surface of a predetermined shoe-like plate material to obtain the three-dimensional shape and texture of the surface of the shoe-like plate material (including but not limited to sewing thread) coating.
