【発明の詳細な説明】 （産業上の利用分野） この発明は、靴の成形法に関するものである。[Detailed description of the invention] (Industrial application field) This invention relates to a method of molding shoes.
（従来の技術）
従来、ゴム靴底を射出成形によって胛被に直接的に加硫
成形する靴の成形方法が提案されているが、ゴムは塩化

ップ部と胛被との間隙より、パリがはみ出し、これがリ
ップ部の上辺において胛被にすり込み付着されるため、
靴成形後パリを除去することが困難であった。(Prior art) Conventionally, a shoe molding method has been proposed in which a rubber sole is vulcanized directly onto a shoe shoe by injection molding, but compared to thermoplastic synthetic resins such as vinyl chloride, rubber Due to the high viscoelasticity during molding, high pressure is required for injection molding, and for this reason, during sole injection molding, the pad protrudes from the gap between the lip of the side mold and the shoe cover, which causes the lip to Because it is rubbed and attached to the cover on the upper side,
It was difficult to remove the pad after shoe molding.
このため靴底成形に先立って、サイドモールドのリップ
部を胛被に強く圧接させることによって、リップ部と胛

った。For this reason, an attempt has been made to prevent the formation of a gap between the lip part and the shoe cover by strongly pressing the lip part of the side mold against the shoe cover before forming the sole, but the lip part prevents the gap from forming between the lip part and the shoe cover. There was a drawback that the cover was eaten away. In addition, in such a method, in order to force the lip of the side mold into strong contact with the sleeve, the same pattern must be used so that no gap is formed between the lip and the sleeve when the side mold is closed. Even in the case of this type of cover, it is necessary to prepare many types of side molds depending on the thickness of the cover, which has the drawback of increasing molding costs.

ものである。(Means for Solving the Problems) This invention will be explained below with reference to drawings showing the state of implementation of the invention.
An unvulcanized rubber tape 2 is pasted on the rubber tape 2, and after it is semi-vulcanized, the lip portion 51.51 of the side mold 5.5 is pressed into the side surface of the rubber tape 2, and the side mold 5.5 is pressed into the lower part of the side mold 5. A sole molding cavity 0 is formed by the mold 5.5 and the bottom mold 6, and this sole molding cavity O
A shoe sole molding material 3' made of unvulcanized rubber is introduced by injection,
The gist of the invention is a shoe molding method characterized by vulcanizing and pressurizing this to form a rubber sole 3 on the lower part of the shoe cover 1, and pressing the lower side of the rubber tape 2 to the shoe cover 1. It is something to do.
この発明において、ゴムテープ２と靴底成形材３′とは
配合的には別配合でもよいが、同一配合にしておけば靴
底３射出成形時に、ゴムテープ２と靴底３とを相互に加
硫一体化できるので便利である。In this invention, the rubber tape 2 and the sole molding material 3' may be mixed separately, but if they are the same, the rubber tape 2 and the sole 3 will be mutually vulcanized during injection molding of the sole 3. It is convenient because it can be integrated.
この発明において、ゴムテープ２の厚みは、サイドモー
ルド５．５を閉じた時、サイドモールドのリップ部５１
．５１と胛被１との間に形成される間隙の幅に応じて、
それよりも厚肉に形成されている。In this invention, the thickness of the rubber tape 2 is such that when the side mold 5.5 is closed, the thickness of the rubber tape 2 is
．． Depending on the width of the gap formed between 51 and the cover 1,
It is thicker than that.

意匠欠けを回避できる。In this invention, the lip portion 51.5 of the side mold
If the lower side part 21 of the rubber tape 2 that is attached to the cover 1 at the lower part of the cover 1 is made thinner than the upper side 22, the lower periphery 11 of the cover 1 which is curved while stretching the lower side 21 Moreover, the tape molding gap OI formed adjacent to the lower periphery 11 of the rubber tape does not narrow the rubber tape, and the tape molding gap 0' prevents the flow path of the sole molding material during sole injection molding. The shoe sole 3 formed in this way can avoid tape chipping and design chipping on the contact surface.
この発明において、ゴムテープ２を胛被１の下周辺１１

に対する密着性が良好となり、貼着作業が能率的に行え
る。In this invention, the rubber tape 2 is attached to the lower periphery 11 of the cover 1.
If you keep the unvulcanized rubber tape warm before applying it to the rubber tape 2, the rubber tape 2 will become soft and
The adhesion to the adhesive is good, and the adhesion work can be done efficiently.

を胛被１に圧着成形するものである。In addition, in this invention, if the last 7 with the shoe cover 1 suspended thereon is heated in advance to keep the shoe cover 1 warm, and the unvulcanized rubber tape 2 is attached to the lower periphery 11 of the heated shoe cover 1, the sole of the shoe can be It is convenient because the rubber tape 2 can be easily semi-vulcanized before molding the rubber tape 3. In this invention, after semi-vulcanizing the unvulcanized rubber tape 2 stuck to the lower periphery 11 of the cover 1, the side mold 5.5 is closed and the lip portion 51.5 of the side mold is closed.
1 is put into pressure contact with the rubber tape 2 attached to the lower periphery 11 of the cover 1, and a side mold 5 is attached to the lower part of the cover 1.
．． 5 and the bottom mold 6 to form a sole molding cavity O, and a sole molding material 3' made of unvulcanized rubber is injected into the sole molding cavity 0 by a conventional method to form a rubber sole 3. At the same time as vulcanization molding, the lower side of the rubber tape 2 is press-molded onto the cover 1.

２を簡単に除去できる。After forming the sole 3 in this way, the side mold 5.5 is opened and the completed shoe is removed from the last 7, and the lip portion 51.51 of the side mold is removed when the sole is formed.
If the upper side part 22 of the rubber tape located at the upper part is torn off from the lower side part 21 and removed, the lower side part 21 of the rubber tape was pressure-bonded and vulcanized to the shoe cover 1 during the sole molding, and the upper side part 22 of the rubber tape is removed. Since it is in a semi-vulcanized state, the upper side 2 of the rubber tape is closer to the lip part of the side mold.
2 can be easily removed.
（発明の作用効果）
この発明は以上のように構成されており、ゴム靴底射出
成形時にサイドモールドのリップ部５１．５１と胛被と

はみ出し形成されたりすることがない。(Operations and Effects of the Invention) The present invention is constructed as described above, and the gap between the lip portion 51, 51 of the side mold and the cover is sealed with the semi-vulcanized rubber tape 2 during injection molding of the rubber sole. As a result, unlike in the past, the collar is not cut off by the lip portion of the side mold, and the pad is not formed protruding from between the lip portion and the collar.
また胛被１が同一パターンで肉厚が相違する場合、ある

る。Also, if the laces 1 have the same pattern but different thicknesses, or even if the laces 1 are of different types such as sneaker type, saddle type, moccasin type, slip-on type, etc., the thickness of the rubber tape 2 can be changed. As a result, the same side mold, last mold, and bottom mold can be used in combination, making the molding cost low and economical.
