Method for making a sole model and a sole model

The invention relates to the manufacturing technology of the sole model, in particular to a method for manufacturing a sole model and a sole model produced, which utilizes the production technology of shell and hollow ribs to save production time and material cost.

In the footwear industry, the sole model is required for the production of each pair of shoes. The traditional method of making the sole model is to use a machinable material, such as wood and plastic, to be machined by a computer numerically controlled machine tool (CNC) to complete the sole model. However, the sole model is often designed with many patterns, bumps or grooves. The overly complex model structure not only causes the computer numerical control tool to be machined for a long time, but also has a problem of machining dead angle that cannot be processed by the machine tool. Manually trimmed. Moreover, the sole model processed by the block material has a solid structure inside, and when accumulated in a large amount, the accumulated weight of the sole model is not only caused by the shelf test of the storage sole model, but also the cost of transportation is increased.

Therefore, for the sole model making, avoiding the occurrence of machining dead angles and reducing the weight of the mold and reducing the raw material cost are still issues to be improved.

In view of the foregoing problems, the main object of the present invention is to provide a method for manufacturing a sole model and a sole model produced by using a laminate manufacturing technique to make a sole model to avoid processing dead angles, and to make the sole model have a cavity and reduce the shell shape. The effect of weight.

In order to achieve the above object, the present invention provides a method of making a sole model comprising the steps a), using a computer having a computer-aided design software for operating a computer-aided design software to generate a digital sole model. And, in step b), the digital sole model is formed by a laminate manufacturing technique, and the shell-shaped mold body forms a cavity through a laminate manufacturing process, and the shell-shaped mold body forms at least one rib disposed in the cavity. .

In addition, the present invention also provides a sole model comprising a shell-shaped mold body forming a cavity, the shell-like mold body forming at least one rib, the rib being disposed in the cavity.

It should be noted that, in the present invention, the laminated manufacturing technology is a three-dimensional printing technique.

Furthermore, the ribs form at least a consistent aperture. Also, the number of ribs is plural, and each of the ribs is located in the cavity and is at right angles to each other.

Referring to Figures 1-2, the present invention provides a method of making a sole model. In the method for manufacturing a sole model, a computer 11 is first prepared, and the computer 11 has a Computer aided design software 111. The user operates the computer 11 and operates the computer aided design software 111 through the computer 11 to generate a digital sole model 12. Next, the user creates the shell model body 15 conforming to the digital sole model 12 through the additive manufacturing technique 13 (Additive Manufacturing). In the present embodiment, the laminate manufacturing technique 13 is a three-dimensional printing technique. Since the multi-layered sole design 12 utilizes the digital sole model 12, the shell-like model body 15 is produced by layer-by-layer stacking of discrete materials (liquid, powder, silk, sheet, plate, block, etc.), which is a bottom-up ( Bottom-up) The manufacturing technique of material stacking, because of the layered stacking material, processing dead angles can be avoided compared to conventional CNC machining. Further, a cavity 151 is formed inside the shell-like mold body 15 through the laminated manufacturing technique 13, and a rib 152 is formed in the cavity 151.

Referring to FIG. 2, the sole model of the present invention comprises a shell-shaped model body 15. It should be particularly noted that the term "shell" as used herein refers to a form having a uniform thickness.

The shell-like mold body 15 defines a cavity 151 which forms at least one rib 152, the rib 152 being located within the cavity 151. By the structural design of the shell-shaped mold body 15 having the cavity 151, the amount of material used can be reduced, and the shell-shaped mold body 15 can be made into a shell shape to achieve weight reduction. By adding the rib 152, the structural strength of the shell-shaped mold body 15 can be enhanced.

Due to the characteristics of the laminated manufacturing technology 13, the manufacturing method of the sole model can be directly made into a shell-shaped model, and there is no disadvantage that the CNC is difficult to process complicated patterns, and the materials used in the laminated manufacturing technology 13 are lighter than the conventional wooden molds, and are easy to store. It is also easier for operators to take. However, the physical strength resistance of the shell model is not as good as that of the solid model, and the material used in the laminate manufacturing technique 13 is difficult to be as solid as a block, so that if the shell model is put into the process of making the mold, the cause may be generated. The strength of the material is not sufficient to resist damage due to process strength. Therefore, the invention is more Further at least one rib 152 is first established in the inner casing cavity of the digital sole model 12 prior to the shell-like model body 15 and directly fabricated by the laminate manufacturing technique 13.

Please refer to Figure 2-4. Since there are many soles and different patterns and groove cavities, even if the strength of each point is not uniform in the same process strength, the present invention can be used in the early stage of design. The sole model of the biting flower, the size, the groove cavity, and the like can be differently processed for the arrangement and shape of the rib 152. In addition to the ribs arranged at right angles, the ribs can be constructed in an equidistant or parallel arrangement. In addition, if the strength is sufficient, only one rib 152 may be built in, or the rib may be capable of supporting the shell-like model in order to prevent damage during the process due to a more complicated structure.

It should be noted that in the present embodiment, the number of the ribs 152 is taken as an example, but the design of the single rib 152 can achieve the effect of the present invention. In addition, each of the ribs 152 forms at least a consistent aperture 153 to enhance weight reduction. Further, each of the ribs 152 is located in the cavity 151 and is at right angles to each other, and the shell-like mold body 15 can also be used to further enhance the structural strength on the basis of the ribs 152.

As can be seen from the above description of the embodiments, the present invention uses the laminated manufacturing technique to make a sole model and the sole model has a cavity 151 and the cavity 151 is enlarged to make the shell-shaped model body 15 have a thin shell shape, which can surely avoid the processing dead angle and reduce The effectiveness of the sole model weight.
