ー内に、予め成形したゴム製、皿状の補強片を固定し、
発泡ポリウレタン液を注型、硬化させるものである。Japanese Patent Publication No. 60-57842 describes a method of manufacturing this type of shoe sole. In this method, a preformed rubber-made dish-shaped reinforcing piece is fixed in the cavity of the shoe sole molding die,
It is used to cast and cure polyurethane foam liquid.

ン液を発泡硬化させ、離型後、該つばを切り取る。<< Means for Solving the Problems >> A method for manufacturing a shoe sole according to the present invention is to place a rubber dish-shaped outsole having an outer shape matching the cavity in a cavity of a lower shoe mold. The upper mold is fitted to the lower mold so that a collar integrally extending outward from the peripheral edge of the outsole is sandwiched therebetween. Then, the polyurethane liquid introduced into the space formed by the inner surface of the outsole and the upper mold is foamed and cured, and the collar is cut off after releasing the mold.
アウトソールの位置決めを容易にするため、該つばに突
条に形成しておき、この突条を該下型の上面に形成され
た溝に係合させるようにすることが必要である。In order to facilitate the positioning of the outsole, it is necessary to form a ridge on the collar and engage the ridge with a groove formed on the upper surface of the lower mold.

４は接地面に形成されている滑り止めの突起である。<< Example >> In this manufacturing method, first, a rubber outsole 1 as shown in FIGS. 2 and 3 is molded using a press mold. The outsole 1 is formed in a dish shape, that is, the rising portion 1b extends around the bottom portion 1a. Further, a thin collar 2 integrally extends from the edge of the rising portion 1b. A protrusion 3 having a semicircular cross section is formed on the lower surface of the collar 2 so as to surround the outsole body. Reference numeral 4 is a non-slip projection formed on the ground surface.
アウトソールの内面は、発泡ポリウレタンとの親和性を
良くするために、事前にプライマー処理する。布を貼っ
てもよい。The inner surface of the outsole is pre-primed in order to improve its compatibility with the polyurethane foam. You may stick a cloth.
このアウトソール１を第１図に示すように、靴底形成用
下型５のキャビティー６内にはめ込む。なお、アウトソ
ール１は、該キャビティー６と同一形状に作られてい
る。As shown in FIG. 1, this outsole 1 is fitted into the cavity 6 of the shoe bottom forming lower die 5. The outsole 1 has the same shape as the cavity 6.
下型５の上面には、溝７が形成されており、この溝に、
アウトソール１のつば２を外側に引っ張るようにして突
条３をはめ込み、アウトソール１と下型５を間に空隙が
できないようにする。A groove 7 is formed on the upper surface of the lower die 5, and in this groove,
The rib 3 of the outsole 1 is pulled outward so that the protrusion 3 is fitted therein so that no space is formed between the outsole 1 and the lower mold 5.
一方、上型８には、甲被９と中底１０を被せたラスト１
１を、該ラスト１１の底が下面から覗くように支持して
おく。On the other hand, the upper mold 8 is covered with the instep 9 and the insole 10 and the last 1
1 is supported so that the bottom of the last 11 can be seen from the lower surface.
準備ができたら、下型５にはめ込んだ皿形のアウトソー
ル１の中に発泡ポリウレタン液１２を注ぎ、下型５の上
に上型８を合わせ閉じる。このとき、アウトソール１の
つば２は両型５，８の間には挟みつけられる。When ready, the foamed polyurethane liquid 12 is poured into the dish-shaped outsole 1 fitted in the lower mold 5, and the upper mold 8 is closed on the lower mold 5. At this time, the brim 2 of the outsole 1 is sandwiched between the molds 5 and 8.
こうして、発泡ポリウレタンの原料液１２は発泡しなが
ら膨張し、型の内部空間を埋め尽くす。つば２が型５，
８の間に挟まれているので、発泡ポリウレタン液がアウ
トソール１の裏側に侵入することはないことに注目すべ
きである。In this way, the raw material liquid 12 of the polyurethane foam expands while foaming and fills the internal space of the mold. The brim 2 is the mold 5,
It should be noted that the polyurethane foam liquid does not penetrate into the back side of the outsole 1 because it is sandwiched between the eight.
なお、原料樹脂液１２は、上下の型５，８を合わせた
後、型の内部に射出してもよい。The raw material resin liquid 12 may be injected into the mold after the upper and lower molds 5 and 8 are combined.
発泡ポリウレタンが硬化したら、型から取り出し、つば
２を切り取れば、靴ができあがる。When the polyurethane foam is cured, remove it from the mold and cut off the brim 2 to complete the shoe.
でき上がった靴は第４図に示すように、発泡ポリウレタ
ン層１３がゴム製アウトソール１ですっぽり覆われたも
のとなる。As shown in FIG. 4, the finished shoe has the polyurethane foam layer 13 completely covered with the rubber outsole 1.
このようなダイレクトソーリング法によらず、靴底だけ
を成形するときは、前記上型８は単なる蓋でよい。When molding only the shoe sole without using such a direct sawing method, the upper mold 8 may be a simple lid.
《効果》 請求項１の製造法においては、アウトソールの周囲に設
けられているつばを上下の型の間に挟むようにしたの
で、発泡ポリウレタン液がアウトソールの裏側に侵入す
ることがなく、したがって、アウトソールの外面に発泡
ポリウレタンが付着することがない。<< Effect >> In the manufacturing method of claim 1, since the brim provided around the outsole is sandwiched between the upper and lower molds, the foamed polyurethane liquid does not enter the back side of the outsole. Therefore, the polyurethane foam does not adhere to the outer surface of the outsole.
また、つばに設けられている突を下型の溝に係合させる
ようにしたので、アウトソールを下型のキャビティー内
に隙間なく保持することができる。Further, since the protrusion provided on the collar is engaged with the groove of the lower mold, the outsole can be held in the cavity of the lower mold without any space.
