Sole manufacturing method with different material studs

The present invention provides a method of manufacturing a sole having a different material stud, which is related to a method of manufacturing a footwear component.

Studs, or foot nails, are mostly placed on the soles of soccer shoes or athletic shoes, mainly for providing shock absorption, improving grip or improving controllability, while the early sole 10 with studs is shown in FIG. The shoe sole 10 is combined with a plurality of studs 11 and the studs 11 are made of a metal material. The studs 11 are screwed to the sole 10 through a screw 111, and the sole 10 is coupled to the shoe body, and the manufacturing process is performed. It is extremely cumbersome and is not conducive to mass production; therefore, there is a method for manufacturing a sole having a stud, which is mainly formed by one injection molding of two plastics having different material properties, thereby improving production efficiency, however, although The stud and the sole have different material properties, but the stud and the sole are still in a plastic material, so that the performance of the stud in the grip is not as expected, so there is still a need for improvement; of course, there is also The sole of rubber studs is made of plastic material, and the studs are made of rubber. Because the forming conditions and working methods of rubber and plastic are not the same, the general shaper And can not be simultaneously molded rubber and plastic, and therefore it is necessary to respectively After the pre-forming, the steps of gluing or bonding are separately performed, and if the glue is not reliably and stably positioned, there may be a lack of bonding stability or a defect in the bonding product; in view of this, the inventors have concentrated on Research and deeper conceiving, after many research and development trials, finally invented a method of manufacturing a sole with different studs.

The present invention provides a method for manufacturing a sole having a different material stud, the main purpose of which is to improve the manufacturing process of a shoe sole generally having a stud, the lack of grip, or the lack of stability of the joint.

In order to achieve the foregoing objective, the present invention provides a method for manufacturing a sole having a different material stud, comprising: sequentially performing a step of forming a stud, forming a stud having an outer surface and a bonding surface; and the step of inserting the stud into the mold The formed stud is placed in a first mold, the first mold has a forming groove, the forming groove has a notch, each of the studs is received in the forming groove, and each of the studs has the outer surface Adhering to the forming groove, after each of the studs is received in each of the forming grooves, a range between each of the studs and the notch of the forming groove is a forming space; a surface treatment step, a coating liquid surface treatment a coating agent on the bonding surface of each of the studs, the surface treating agent is a butanone treating agent, after coating and drying; then a colloid molding step, after the surface treatment step, a colloid is placed into the forming space and Applying to the surface treatment agent; clamping the second mold to the first mold, the second mold has a corresponding forming portion, and the second mold is provided with a feeding passage through the corresponding forming portion. The second mold has the corresponding forming portion Clamping the molding groove and the slot closed, and the feeding into the communication channel Forming space; the sole material is ejected, the sole material is heated and melted into a liquid state, and the material is injected into the forming space, the sole material and the stud are made of different materials; and the hot-melt bonding step is performed after the sole material is injected into the forming space. The heated melted sole material is then combined with the bonding surface of the stud through the adhesive body; the input of the sole material is stopped and then the colloid is melted and then cooled, and after cooling, the sole material is cooled and hardened into a sole, and the colloid is cooled and solidified. The sole and each of the studs; and a mold opening step of separating the first mold and the second mold and removing the through-sole combined sole and the stud.

The present invention simplifies the production process and improves the production efficiency and economic benefit by placing the preformed stud and the colloid in the injection molding die, forming the sole and then the stud through the process of colloid and injection molding.
