Description

Transfer printing method for integrally molded colored soles

The present invention relates to a transfer printing method for integrally formed colored soles, in particular, it is applied to general shoe sole forming molds by using transfer printing paper to produce soles with colorful patterns.

Since the production of general shoe soles uses rubber as the main material, it uses hot pressing to produce soles with raised lines on the bottom surface. Therefore, the rubber only has a single color, so the produced soles cannot have colorful patterns. If you want to shape the soles After processing to produce soles with colorful patterns, because the soles have been formed with embossed patterns, it will be quite difficult to reprocess and draw patterns, so the cost is not economical.

In view of this, the inventor, with years of experience in this industry, actively researched and developed, and after actually verifying its feasibility, finally produced the present invention's "transfer printing method for an integrally formed colored sole".

The main purpose of the present invention is to provide a manufacturing method for printing color patterns on the sole while the sole is being formed.

Its main feature is that it uses a pre-printed transfer paper with colored patterns to stick it on the bottom mold of the shoe sole molding mold, and then puts the shoe sole material on the transfer paper to make the pressure mold squeeze Put the shoe sole material together with the transfer paper on the bottom mold, and raise the press mold and the bottom mold to a specific temperature to shape the shoe sole material and transfer the pattern of the transfer paper to the formed shoe sole material at the same time, to achieve The purpose of printing colorful patterns on the soles.

In order to enable the examiner to have a better understanding of the method and its features of the present invention, a detailed explanation is given below with the accompanying drawings.

Fig. 1 is a flow chart of the method of the present invention.

Fig. 2 is a schematic diagram of the present invention applied to a shoe sole molding die.

As shown in the flow chart of Fig. 1, the transfer printing method of the integrally formed colored sole of the present invention is mainly to use a transfer paper and be applied on a sole forming mold to make a sole with a color pattern, and the sole forming mold Can refer to shown in Fig. 2, it comprises a bottom mold 10 and a pressure mold 11, can insert a sole material 20 (such as rubber etc.) between this bottom mold 10 and pressure mold 11, and this bottom mold 10 is to have The opposite groove shape lines of the required shoe sole embossment, and the stamper 11 is used to apply pressure to the sole material 20 to make it stick to the bottom mold 10 and form it. Since the shoe sole molding mold is a known structure, No more details here; and the method of the present invention comprises the following steps:

Firstly, pre-design the color pattern to be printed on the sole into a pattern draft.

Utilize the mode of color printing to print this pattern draft on a transfer paper 30, at this moment, the pattern on this transfer paper is just the inverse pattern of the original pattern draft, and the ink that it uses can be resin It has the characteristics of high temperature resistance.

Thereafter, the transfer paper 30 printed with colored patterns is pasted on the bottom mold 10 of the shoe sole forming mold, wherein the pattern on the transfer paper 30 can be compared with the bottom at the beginning of the pattern draft design. The depression 101 of the mold 10 leaves a blank 301, so that when it is pasted on the bottom mold 10 of the shoe sole forming mold, the blank 301 can just stick to the depression 101 of the bottom mold.

Then, actuate the die 11 of the shoe sole forming mold, make the die 11 squeeze the sole material 20 together with the transfer paper 30 on the bottom die 10, and raise the die 11 and the die 10 to a specific temperature If it is a rubber material, its forming temperature is about 150 degrees centigrade, so that the shoe sole material 20 is shaped according to the grooves designed by the bottom mold 10, and at the same time, the pattern of the transfer paper 30 is transferred to the existing Formed sole material 20.

Finally, the stamper 11 is opened to take out the sole material 20 printed with a colored pattern, and the material other than the required sole shape is removed to become the final finished product of the sole.

Furthermore, because the transfer paper 30 will be squeezed by the die 11 and the bottom mold 10, in order to avoid the phenomenon of cracking during the extrusion process, the transfer paper can be made of an elastic material so that the extrusion process The transfer paper in has the proper toughness without cracking to maintain the integrity of the pattern.

In addition, in the above method, the purpose of leaving blanks on the transfer paper 30 relative to the depressions 101 of the bottom mold 10 is that when the sole is formed, the depressions 101 of the bottom mold 10 are just the protruding lines of the sole, and the convexity The pattern is used to be in contact with the ground, so there is no need to print a pattern, so there is a blank at the recessed part 101 relative to the bottom mold 10 .

From the above disclosure, it can be seen that the method of the present invention is mainly to apply a transfer paper to a shoe sole molding mold, and the transfer paper printed with a pre-designed pattern can be pasted on the bottom mold of the shoe sole molding mold, and It is integrally formed with the sole, and its advantage is that it can print the color pattern simultaneously during the forming process of the sole. appearance.

Based on the above, the "transfer printing method of integrally formed colored sole" of the present invention can indeed achieve the expected effect through the above method, and it has not been seen in publications or used publicly before the application, which meets the requirements of the patent.
