てはよく知られている。About a method for manufacturing slush-molded shoes having anti-slip elements integrated into the sole by placing anti-slip elements in advance at predetermined locations on the bottom contact surface of a slush-molding mold, and then slush-molding plastisol, such as vinyl chloride paste, by a conventional method. is well known.

滑子をどの工程で底に取りつげるかが問題となる。In plastisol slush-molded shoes, plastisol is injected into the mold, heated from the outside of the mold, and the plastisol in contact with the inner wall of the mold becomes a semi-gel.
A layer of desired thickness with no fluidity is formed, then the mold is turned upside down, the ungelled plastisol in the mold is allowed to flow out, and the semi-gelled layer remaining on the inner wall of the mold is heated again and melted. By doing this, the sole of the uniform gel layer and the laces are integrated to form a shoe body, and the interior is processed as appropriate to create a product. In manufacturing, the problem is which process to attach the anti-slip element to the bottom.

を有するスラッシュ成形靴の製造方法が知られている。The conventional method is to first form a groove for embedding the anti-slip element in a predetermined location on the ground surface side of the bottom of the slush mold, simply insert the foot of the anti-slip element into this groove, and then inject plastil. A method for producing slush-molded shoes with a slip preventer at the bottom is known by heating the mold to form a semi-gelled layer on the inner surface, inverting the mold, and discharging the ungelled plastisol. It is being

に確実に埋設することが困難である。In this method, the mold is tilted or moved during the process of injecting plastisol into the slush mold, heating the mold, or discharging ungelled plastisol, so the slip preventer separates from the mold groove. , moving or falling over, making it difficult to reliably embed the anti-slip element in a predetermined position in the sole.

ゲル化層を損傷し不良品にする危険が大きい。Next, a recess into which the foot can be inserted is formed on the bottom ground side of the slush mold, and plastisol is injected into this mold and heated to form a semi-gelled layer on the inner surface. The foot of the shoe is inserted into the recess and held by the elastic recovery force of the semi-gelled layer within the recess.Then, the inner layer is welded to the outer layer using plastisol that is compatible with the outer layer, and at the same time the anti-slip element is attached to the sole. In the method of manufacturing slush-molded shoes that are buried, after injecting plastisol into the slush-molding mold, the mold must be heated to form a semi-gelled layer on the inner surface of the mold. The semi-gelled layer becomes hot and there is a risk of burns, so the worker cannot work with bare hands, so he picks up the anti-slipper with his hands protected by thick gloves, and fills it with the semi-gelled layer. The operator has to insert it into the recess, which is extremely troublesome and inefficient, and the recess is covered with a semi-gelled layer, making it difficult to know where it is. The child must be inserted into the recess, which is an uncertain and inefficient operation, and may touch the semi-gelled layer on the inner wall of the mold, damaging the formed semi-gelling layer and resulting in defective products. There is a great risk of doing so.

および防滑子の接着作業は面倒かつ困難である。Furthermore, a protrusion having the same shape as a polyvinyl chloride anti-slip element made by partially enlarging the anti-slip metal core is provided at a predetermined location on the ground surface side of the bottom of the slush molding mold, and plastisol is injected into this mold. A slush molded shoe is molded using a conventional method, and the anti-slip element is fitted and fixed into a recess formed at a predetermined location on the ground surface of the sole of the slush-molded shoe. In the method for manufacturing molded shoes, the anti-slip element is bonded with an adhesive to the recess formed in the bottom of the slush molded shoe after molding. Since the mold release agent is resistant to adhesion, the work of applying adhesive to increase the adhesive force and the work of gluing the anti-slip element are troublesome and difficult.

業が面倒で不経済であった。Furthermore, as clearly disclosed in Japanese Patent Publication No. 47-28221, if the tip of the vulcanized soft rubber piece of the core material of the anti-slip fitting is inserted into the recess provided in the ground plane of the heel part of the slush mold. The vulcanized soft rubber piece is held in the concave part by its elasticity, and then, in the method of manufacturing non-slip slash shoes having a vulcanized rubber piece with a non-slip fitting name attached to the heel part, the vulcanized soft rubber piece is held in the concave part by its elasticity. If you try to insert each leg of the non-slip metal core surrounded by a soft rubber piece into the recess so that it will not fall even when the slush mold is turned upside down, the elasticity of the rubber piece It is not easy to insert the rubber piece because it is repelled by the force, and since the recess is narrow and individually sealed, when the rubber piece is inserted into the recess, the air inside the recess is hermetically compressed. As a result, it becomes difficult to insert the shoe into the specified position, and the sulfur rubber piece with the non-slip metal fitting comes into contact with the heel of the wearer, making it difficult to obtain the desired slush-molded shoe. The repair work was troublesome and uneconomical.
