製造されている。Conventionally, the manufacturing method for this roll-up sole usually involves using an unvulcanized rubber compound that has a small elastic recovery rate during vulcanization, a design mold having a sole design shaping surface that shapes the design surface of the sole, and a design mold that has a sole design shaping surface that shapes the design surface of the sole. It is placed in the cavity for sole molding formed inside the mold of a shoe sole molding mold consisting of a lid mold that fits into the design mold, and then the sole molding mold is heated at room temperature or relatively low temperature. It is manufactured using the cold press method, which pressurizes the shoe to form the sole.

なシート状のものが使用されている。In addition, the mold temperature of this mold for forming shoe soles is 70 to 9, which is the same mold temperature for both the design mold and the lid mold.
0 'C, and the unvulcanized rubber compound used in this method of manufacturing soles is usually a smooth sheet with powdered zinc stearate having a melting point of 116"C, which is a lubricant, sprinkled on the surface. are used.

取り出し難かった。In addition, as mentioned above, both the design mold and the lid mold a have the same mold temperature of 70 to 90°C, so when the mold is removed from the mold after sole molding, the molded sole is not in the design mold or the lid mold. Which side of the lid mold should it be attached to?
Each manufacturing case was different, and it was difficult to remove the sole from the mold for forming the sole.

となる恐れもあった。Furthermore, as mentioned above, compared to the mold temperature (70 to 90°C) of the design mold and the lid mold, the melting point of zinc stearate, which is the powder sprinkled on the surface of the sheet of unvulcanized rubber compound, is 116°C. Because of this high temperature, when this heated mold is press-fitted to form the sole (hereinafter simply referred to as "pressing"), the powder does not melt and migrate into the unvulcanized rubber compound. There was a risk that the product would be deposited on the design surface of the sole of the design mold, thereby staining the design mold, or that the reproducibility of the design would be insufficient, especially if the design to be molded was sharp.

Ｃ，蓋モールドが６０〜９０℃としている。[Function] In the method for manufacturing a shoe sole of the present invention, first, an unvulcanized rubber compound having a small elastic recovery rate during vulcanization is molded into a design mold having a sole design contour surface that shapes the design surface of the shoe sole. The design mold is inserted into a sole molding cavity formed inside the mold of a shoe sole molding mold, which is made up of a lid mold that is fitted into the design mold. At this time, the mold temperature is 100~130'' for the design mold.

きる。Further, as the filler added to this rubber raw material, for example, a silicic anhydride-based filler can be used. As this silicic anhydride-based filler, for example, it is generally called white carbon and contains silicic anhydride and a small amount of water. It is a reinforcing filler and is commercially available under trade names such as Hi-Seal, Carplex, Nib-Seal VN-3, and Toku-Seal TP. In addition to this silicic anhydride filler, sulfur, a vulcanization accelerator, etc., which are commonly used as compounding agents for rubber, can be mixed and used at the same time.

なお、そのほか、未加硫ゴム配合物１０中には、−船便
用されている種々の添加剤も添加することができる。In addition, various additives commonly used in shipping can also be added to the unvulcanized rubber compound 10.
そののち、第２図に示すようにこの所定温度に加熱され
た靴底成形用金型Ｘを加圧嵌合して靴底Ｋを成形させる
。Thereafter, as shown in FIG. 2, the sole molding die X heated to a predetermined temperature is fitted under pressure to form the sole K.

靴底にの取り出しも容易となる。In this way, the mold temperature of the design mold 20 is 100 to 1
Because the temperature is as high as 30°C, the flow viscosity of the melted unvulcanized rubber compound 10 is relatively low, and therefore, the unvulcanized rubber compound 10 fits well into the narrow surface 20a with the sole design of the design mold 20. At the same time, when releasing from the mold after forming the shoe sole, the molded sole K is more likely to separate from the relatively high temperature design mold 20 than the relatively low temperature lid mold 30 due to the flow temperature. It is also easy to take out the shoe sole after molding from inside the sole molding mold X.

の再現性の低下をも防止することができる。Further, dust powder such as zinc stearate (not shown) sprinkled on the surface of the unvulcanized rubber compound 10 also becomes molten and enters the unvulcanized rubber compound 10 due to the high heating temperature of the design mold 20. Therefore, staining of the design mold 20 and deterioration of design reproducibility caused by the adhesion of powder (not shown) can also be prevented.

製造するものである。In addition, the sole manufactured in this way has, for example, a third layer.
As shown in the figure, while applying adhesive to the lower part of the shoe cover 50, wipe the surface to which it is attached to the sole with a solvent. Roll it up to the veranda and stick it to the lower part of this cover 50 using a notebook, and then, for example, at a temperature of 130" C1 and an air pressure of 3 kg.
By placing the shoes in a c4 indirect vulcanizer for 55 minutes to cure the sole and the adhesive, a sole K with 2 rolled up at the toe and 3 rolled up at the heel is formed at the bottom of the shoe cover 50. Shoes S having the following are manufactured.

う効果が得られる。In the present invention, when molding the shoe sole by pressure fitting the shoe sole molding mold in this way, the mold temperature of the design mold is 100%.
Since the temperature is as high as ~130'C, the viscosity of the melted unvulcanized rubber compound is relatively low, and therefore the unvulcanized rubber compound blends well with the designed face of the sole of the design mold, and the viscosity of the unvulcanized rubber compound is relatively low. When releasing from the mold after sole molding, due to flow temperature, the molded sole is more likely to separate from the relatively high temperature design mold than from the relatively low temperature lid mold. The effect is that the sole can be easily taken out after molding.

という効果も得られる。In addition, the dust sprinkled on the surface of the unvulcanized rubber compound melts due to the heat of the design mold, which is heated to a relatively high temperature, and migrates into the unvulcanized rubber compound. It is also possible to prevent staining of the design mold and deterioration of design reproducibility caused by adhesion of powder.
