The press mold (4) has a lower mold (4a) having an uneven pattern (4ax) on the bottom surface, and an upper mold (4b) that cooperates with the lower mold (4a). , a cavity (4c) for molding a raised sole is formed. Furthermore, the mold surface of the lower mold is subjected to mold release treatment with a slight difference in the shape property so that the i-shaped object always adheres to one of the mold surfaces and is released from the mold. It is preferable to keep it. In the figure,

As shown in Figure 2, a rubber piece (3) is set in the lower mold (4a) of the press mold (4) using a press machine (not shown).
Pressure molding is performed (see Figure 8), and then the mold is released, resulting in an unvulcanized rubber shoe sole (5) with a raised portion (6a) shaped like a pot bottom, as shown in Figure 4. is obtained. The figure shows the case where an unvulcanized rubber sole (5) with a raised part is molded in one step using a press mold (4), but multiple types of upper molds are prepared, and the raised part (6a) is molded in one step. The process may be divided into several steps and molded in stages.

Considering processability, it is advantageous to carry out the process at a relatively low temperature in which vulcanization does not substantially occur.
The appropriate heating temperature is about 20 to 80° C., although it depends on the composition of compound (1).

For heating, there are cases where the unvulcanized rubber compound (1) is preheated, and there are cases where the press mold (4) is constantly heated (or cooled) to a predetermined temperature of IXK, and both are usually used in combination. . The molding pressure and molding time during the pressure molding operation are not particularly limited. It is selected and determined as appropriate, taking into consideration the temperature, the molding height of the rising portion, etc.

The rising part (6a) of the unvulcanized rubber sole (5) may be formed all around the circumference as shown in Figure 6, or it may be formed in a part as shown in Figures 6 and 7. may be formed;
In some cases, as a typical example, the toe part (see Figure 6),
The toe portion and heel portion (see FIG. 7) are illustrated. Of course, it may be formed only on the heel portion or the circumferential side portion. Since it is a plain molding method, even a rubber sole whose thickness gradually increases toward the heel as shown in FIG. 8 can be easily molded.

In this case, as shown in FIG. 9, press ff! If the rising portion (6a) is molded to open slightly outward from a predetermined dimension when forming the L-shape, the fitting work will be facilitated, and workability can be further improved. In this case, as shown in Figure 9, a gap (8) is created between the rising part (6a) and the lower side surface of the cover (7), but the rising part (6a) is unvulcanized and has no plasticity. Therefore, the rising portion (6a) can be easily brought into close contact with the opposing surface by applying pressure from the direction of the arrow (9), such as an air bag, as shown in FIG. 10, for example. The fitting attachment of the unvulcanized rubber sole (5) to the bottom surface of the shoe cover (7) is sometimes carried out as shown in Fig. 9.
After wiping the bonding area between the two with a solvent to remove the glue, an adhesive layer αQ such as a rubber, rubber glue layer or thin unvulcanized rubber tape is formed, and if there is a recessed part αIJ on the lower surface of the joint, VC is ,
It is preferable to fill it with a vulcanizable sheet tent or other suitable filler. In the jg9 diagram, the strawberry is in the middle,
α4 is the center core, and there are no restrictions on the use thereof, and the center sole 0 may be sewn over the lower edge K of the sleeve cover (7) as shown in FIG. The lower surface of the other yoke (7),
An appropriate intermediate member such as a sponge member α9 as shown in FIG. 14 may be interposed between the rubber soles (5). If dirt or small scratches are found on the side surface of the rising portion (6a), they can be easily repaired by wiping with a solvent or further cleaning.

FIG. 12 shows a product obtained using the rubber shoe sole shown in FIG. 8, in which reinforcements by rising portions (5a) K are formed at the toe and heel. Furthermore, when a rubber shoe sole (5) having a rising portion (5a) around the entire circumference as shown in FIG. 5 is used, the lower part of the shoe cover is reinforced over the entire circumference as shown in FIG. , the rising portion (5a) functions as a tape winding portion.

Figure 15 shows the elastic recovery rates of the unvulcanized and vulcanized rubber soles of the rubber soles with raised parts press-molded using the unvulcanized rubber compound having the above-mentioned composition as shown in Fig. 15. Table 1 shows the results of the tests for parts B, B, 0, and D.

Effects As described above, according to the manufacturing method of the present invention, the unvulcanized rubber shoe sole is molded using the cold press 7 method, so it is possible to eliminate the defects in design that can be seen in the case of the conventional one-calender method. The formation of the rising part not only improves the workability of aligning the lower surface of the shoe and the rubber sole, but also eliminates the troublesome work steps such as wrapping tape and pasting reinforcing pieces, which were previously considered indispensable. Overall, this type of shoe has features that simplify the manufacturing process.

Furthermore, in the present invention, since the raised part of the sole is integrally formed, the dimensional accuracy is much better than in the case of a separate structure, and the setting is always accurate regardless of the complex curved surface of the shoe. Not only can it be installed easily, but it is also strong and durable.
It is characterized by the ability to manufacture products with good appearance and quality without producing substandard or defective products.

Furthermore, in the present invention, on the lower surface of the shoelace suspended from the shoe last,
When fitting the rubber sole at the rising part, the rubber sole is still unvulcanized, and by utilizing its plastic deformability, fIk can be adjusted appropriately to a maximum of about 5 to 10 mm. Even if a dimensional error occurs on the bottom surface of the shoe due to variations in the thickness of the last or shoe material, this dimensional error can be corrected and absorbed by fine-tuning the dimensions of the rubber sole, making it possible to perform fine-tuning work on nine dimensions. It can be easily and easily carried out using the rising portion as a reference, and such fitting and attachment work can be carried out without any trouble, regardless of the dimensional error that occurs on the side of the cover.

(1) Pressure molding an unvulcanized rubber compound that has plasticity at room temperature or relatively low temperature and has a small elastic recovery rate upon vulcanization at room temperature or relatively low temperature to form a desired uneven pattern on the bottom surface. In addition, an unvulcanized rubber sole having a raised part integral with the main body is molded on part or all of the periphery, and this unvulcanized rubber sole is hung on the lower surface of the shoe last, as necessary. A method for manufacturing shoes with rubber soles, which comprises combining with other appropriate members, fitting and attaching the shoes, and then subjecting the shoes to hot air vulcanization in a conventional manner.
