Therefore, the above is a description of each component of the device 100 for integrally forming the upper three-dimensional texture provided by a preferred embodiment of the present invention, and the assembly manner thereof, and then the following features are described as follows:

First of all, when the invention is in operation, it is located by two operators respectively. On the side of the mold carrier 40 below the heater 60, each operator takes a colored upper semi-finished product 90 having a plurality of positioning holes 91, and places it on the gas permeable mold 50 at the corresponding position. Each positioning post 52 on the gas permeable mold 50 extends through each of the positioning holes 91 to position the upper semi-finished product 90 on the gas permeable mold 50.

Next, the indexing disk 20 drives the turntable 30 to perform a 90 degree (including but not limited to 90 degrees) rotation, and the mold carrier 40 of the upper semi-finished product 90 is placed and rotated to the position below the heater 60 (as shown in FIG. 4). ). At this time, the linear reciprocating unit 70 is actuated to rise to the rising position (as shown in FIG. 5), so that the top cover 81 of the negative pressure generator 80 abuts against the position of the corresponding air guiding hole 34, and the negative pressure generator is made. The suction generator 84 of the 80 and the electromagnetic valve 83 are opened, and suction is generated to the air guiding hole 34, so that the gas in the mold carrier 40 passes through the air passage 413, the air suction hole 412, the air guiding hole 34, the top cover 81 and the air delivery pipe 82, It is aspirated by the suction generator 84 (as shown in Fig. 6). The mold positioning area 411 of the mold carrier 40 is in a vacuum negative pressure state, and the gas permeable mold 50 has a gas permeable characteristic; therefore, the vacuum suction state is formed in the mold positioning area 411, and the suction force is also transmitted through the gas permeable mold 50. And forming a suction force on the upper semi-finished product 90, so that the upper semi-finished product 90 is properly adhered to the three-dimensional grain 51 of the gas permeable mold 50; at this time, the upper semi-finished product 90 is heated by the heater 60, and further The surface of the upper semi-finished product 90 is softened, and the effect of shaping the negative pressure is increased.

After being heated for a predetermined period of time, the solenoid valve 83 of the negative pressure generator 80 and the suction generator 84 are closed, so that the negative pressure generator 80 no longer generates suction to the gas permeable mold 50 and the mold positioning area 411; and the linear reciprocating unit 7 is engaged. 0 moves linearly to the lowered position, and the top cover 81 is disengaged from abutting against the turntable 30 (as shown in Fig. 7). At this time, the indexing plate 20 drives the turntable 30 to rotate 90 degrees (including but not limited to 90 degrees), so that the negative-formed upper semi-finished product 90 and its mold carrier 40 are rotated to the position below the non-heater 60. The upper semi-finished product 90 of the upper pressure-finished shape is conveniently removed by the operator from the gas permeable mold 50 to obtain an upper formed three-dimensionally textured upper.

It can be seen from the above description that the present invention utilizes the method of negative pressure and heating, and can integrally shape the three-dimensional texture on the upper, which is not only labor-saving in comparison with the conventional method of manually or multi-machine operation.
