With reference to
In addition, the shoe-upper material 11 is a one-piece three-dimensional braid, but the invention is not limited to the braid only, but any other equivalent material such as leather can be used instead. Since the shoe-upper material 11 is formed by a weaving method, and weaving threads are usually not closely woven, therefore the shoe-upper material 11 has a plurality of pores 113.
When the melted plastic material 13 is coated onto the shoe-upper 111 and the footrest underside 112 of the shoe-upper material 11, the plastic material 13 is covered onto the shoe-upper 111 and the footrest underside 112 of the shoe-upper material 11 and also permeated into the plurality of pores 113 of the shoe-upper material 11, After the plastic material 13 is cured gradually within a period of time the plastic material 13 permeated into the plurality of pores 113 is cured to connect and seal each pore 113, so that the plastic material 13 can be attached tightly onto the shoe-upper material 11.
However, the shoe-upper material 11 is a braid with insufficient supporting force to support its own weight and the shoe-upper material 11 is a three-dimensional form, so that when after the plastic material 13 is cured, the plastic material 13 has a specific hardness to become a three-dimensional structured support member 131 for supporting the shoe-upper material 11, and the framework of the shoe-upper material 11 is generally attached onto an external surface (including the shoe-upper 111 and the footrest underside 112) of the shoe-upper material 11 to provide a supporting force to the whole shoe-upper material 11 and support the shoe-upper material 11 in a three-dimensional form.
Beside providing the supporting force to the shoe-upper material 11, the support member 131 also has other functions, such as the adjustment of the mold according to the design requirements during the manufacture, so that when the plastic material 13 is injected to the shoe-upper material 11, the plastic material 13 forms a stylish form corresponding to the mold on the shoe-upper material 11, and the plastic material 13 has a specific shape on the shoe-upper material 11, and the color of the plastic material 13 is selected to match with the color of the shoe-upper 111 while completing the coloring operation. The invention can save the manufacturing cost and time effectively. For example, the conventional shoemaking methods require attaching the stylish parts one by one onto the shoe-upper material 11, and some methods even require a sewing process to fix the parts. Now, the present invention injects the plastic material 13 directly to form the parts onto the shoe-upper material 11, not only achieving a better attachment of the parts with the shoe-upper material 11, but also saving the manpower and manufacturing time required for the attaching and sewing operations effectively.
It is noteworthy that the shoe-upper material 11 cannot support itself before the manufacture, so that it is necessary to use a shoe shaped inner mold 14 installed inside the shoe-upper material 11 to provide a supporting force during the manufacture. The detailed description of the shoemaking method of an automated process production is given below.
Even though the concept of shoemaking method of an automated process production of the present invention has been described in the process of describing the shoes of an automated process production of the present invention, the following flow charts are provided to give a more detailed description of the shoemaking method.
With reference to
S11: Providing a one-piece three-dimensional structured shoe-upper material, wherein the shoe-upper material includes a shoe-upper and a footrest underside, and the shoe-upper is coupled to the footrest underside along an edge of the footrest underside.
S12: Providing a shoe sole, installed at the footrest underside and disposed at a position corresponding to the footrest underside.
S13: Coating a plastic material onto the shoe-upper and footrest underside and filling the plastic material between the footrest underside and the shoe sole by a gluing step to glue the shoe sole to the footrest underside.
S14: Forming at least one support member attached onto the shoe-upper and the footrest underside by the plastic material to support the upper material.
In addition, the gluing step further comprises the following steps:
S131: Setting the shoe-upper material onto a shoe shaped inner mold, wherein the shoe shaped inner mold can be a movably stretchable shoe last, and adjust the size of the shoe-upper material to fit different sizes of shoes.
S132: Putting the shoe-upper material and the shoe sole in a shaping mold body having at least one preset mold cavity, and pressing the shoe-upper material by the shaping mold body, wherein the shaping mold body includes at least three movable shaping mold blocks having the at least one preset mold cavity. For example, this embodiment adopts three mold blocks for pressing both sides of the shoe-upper and the footrest underside respectively, but the quantity of mold blocks is not limited to three but it can be adjusted according to actual requirements. It is noteworthy to point out that the shoe sole is placed onto one of the mold blocks corresponding to the footrest underside.
S133: Injecting a plastic material into the at least one preset mold cavity of the shaping mold body by a plastic injection molding machine to coat the plastic material onto the shoe-upper and the footrest underside and fill the plastic material between the footrest underside and the shoe sole.
S134: Removing the shoe shaped inner mold and the shaping mold body by a demolding step.
Before the demolding step takes place, the shoemaking method of the invention further comprises the following steps:
S1331: Permeating the plastic material into the plurality of pores of the shoe-upper material to connect the plastic material to the shoe-upper material.
S1332: Waiting till the plastic material is cured and shaped, the plastic material forms an intermediate glue layer between the footrest underside and the shoe sole to glue the shoe sole to the footrest underside.
For short, the shoe-upper material and the shoe sole are placed into predetermined positions in the mold, and then an injection molding method is used to inject the melted plastic material into the mold and shape and cure the plastic material in the mold, while the plastic material is tightly fixed onto the shoe-upper material, and the shoe sole is also tightly fixed onto the plastic material of the footrest underside. Therefore, the manufacturing process can be simplified to facilitate the manufacture, and the plastic material can be used effectively to support the shoe-upper material and fix the shoe sole, while giving a decorative effect.
The detailed description and implementation of the shoemaking method of an automated process production of the present invention have been described previously in the section of the shoes of an automated process production of the present invention, and thus will not be repeated.
