この発明は、軟質合成樹脂板等軟質シート表面に凸部を
形成するための金形およびその金形を用いた凸部形成方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mold for forming protrusions on the surface of a soft sheet such as a soft synthetic resin plate, and a method for forming protrusions using the mold. be.
（従来の技術）
従来、マットやサンダル合算軟質合成樹脂等軟質シート
の表面に凸部を形成する場合には、第１図に示すように
、多数の凹部２を設けた金形１を用い、金形ｌの凹部２

熱加圧して凹部内へ合成樹脂を没入させ、冷却して凸部
を形成している。(Prior Art) Conventionally, when forming convex portions on the surface of a soft sheet such as a mat or a soft synthetic resin for sandals, a mold 1 having a large number of concave portions 2 is used as shown in FIG. Concave part 2 of mold l
A synthetic resin plate 3 is placed on the mold from above, heated and pressurized in the direction of the recess 2 to force the synthetic resin into the recess, and then cooled to form a convex portion.
（発明により解決しようとする課題）
従来の方法では、金形ｌに合成樹脂板３に加熱加圧した
場合に、凹部２内の空気４の逃げ場がなく、合成樹脂板
３が凹部２の底まで没入せず、従って金形工どおりの凸
部が出来ない。(Problem to be Solved by the Invention) In the conventional method, when the synthetic resin plate 3 in the mold l is heated and pressurized, there is no place for the air 4 in the recess 2 to escape, and the synthetic resin plate 3 collapses to the bottom of the recess 2. Therefore, the convex part cannot be formed as the metal molder does.
そこで金形の凹部の底にピンホールを設けて空気抜きを
する方法も採用されているが、この場合、成形して出来
た凸部の先端に、更に小さい凸起が出来て、そのままで
は商品となら、ず、凸部の数が多い場合にはこの除去の
ために大変な時間と手数がかかる問題がある。Therefore, a method of venting air by making a pinhole at the bottom of the concave part of the mold is also adopted, but in this case, an even smaller convexity is formed at the tip of the convexity formed by molding, and if it is left as it is, it will not be a good product. If there are a large number of protrusions, there is a problem in that it takes a lot of time and effort to remove them.
更にサンダルにおいては、サンダル台につっかけベルト
をミシンを使用して縫い付けるためにはサンダル台を約
８０鶴以下厚みにする必要があるが、従来の有底凹部の
ある金形では加圧のために相当厚い軟質合成樹脂シート
で加圧し冷却した後に、サンダル台を削いで薄くする必
要があり、時間および材料を無駄にしている。Furthermore, for sandals, in order to use a sewing machine to sew a belt onto the sandal base, the thickness of the sandal base must be approximately 80 mm or less, but with the conventional mold with a bottomed recess, it is difficult to apply pressure. Therefore, it is necessary to pressurize and cool the sandal base with a fairly thick soft synthetic resin sheet and then shave the sandal base to make it thinner, which wastes time and materials.
この発明は、従来の技術の上記欠点を改良して、製作に
手数および費用がかからず、使用の簡便な金形およびそ
の金形を使用して凸部形成方法を提供することを目的と
する。An object of the present invention is to improve the above-mentioned drawbacks of the conventional technology and provide a mold that is easy to use and does not require much labor and cost to manufacture, and a method for forming a convex portion using the mold. do.
（課題を解決するための手段） 金形において、有底の凹部の代わりに貫通孔を設ける。(Means for solving problems) In the mold, a through hole is provided instead of a bottomed recess.
貫通孔を設けた金形に皮、ゴム、合成樹脂等の軟質シー
トを当接させ、加熱加圧した後、冷却し、軟質シートの
表面に凸部を形成する。所望の凸部の高さは、加圧圧力
の調整または貫通孔の径の選定により求められる。A soft sheet made of leather, rubber, synthetic resin, etc. is brought into contact with a metal mold provided with through holes, heated and pressurized, and then cooled to form convex portions on the surface of the soft sheet. The desired height of the convex portion is determined by adjusting the pressurizing pressure or selecting the diameter of the through hole.
軟質シートを金形に加熱加圧する際に、金形に軟質シー
トを当接させ、更に軟質シートにゴムシート等軟質シー
トを重ねた後、ゴムシートを介して加熱加圧すれば、薄
い軟質シートの表面に凸部を形成することができる。When heating and pressing a soft sheet into a mold, the soft sheet is brought into contact with the mold, and a soft sheet such as a rubber sheet is placed on top of the soft sheet, and then heated and pressed through the rubber sheet to form a thin soft sheet. A convex portion can be formed on the surface.

配置に従う。(Example) As shown in FIG. 2, a through hole 6 is bored in a zeta mold 5. The diameter of the through hole 6 is designed depending on the diameter of the convex portion desired to be formed in the soft synthetic resin sheet. The arrangement of the through holes 6 follows the arrangement of the convex portions to be formed.

シートの裏面を削ればよい。The method shown in FIG. 3 uses a relatively thick soft synthetic resin sheet 7.
This is for forming a convex portion 8 on the surface of the plate. That is, when the soft synthetic resin sheet 7 is brought into contact with the mold 5 and heated and pressurized, a part of the soft synthetic resin sheet 7 sinks into the through hole 6. When a predetermined pressure P is applied and the sheet is cooled, the portion recessed into the through hole 6 is formed as a convex portion 8 on the surface of the soft synthetic resin sheet. Shallow recesses 9 are formed on the back surface of the soft synthetic resin sheet 7 at positions corresponding to the protrusions 8. The recesses 9 improve cushioning properties, but if they are not necessary, the back surface of the soft synthetic resin sheet can be scraped off.

When the soft sheet 7a is cooled and taken out, the portion recessed into the through hole 6 forms a convex portion 8. The height of the convex portion 8 is adjusted by the strength of pressure or the diameter of the through hole. The recess 9a formed on the back surface of the soft synthetic resin 7a is larger than the recess 9 in the case of FIG. 3, even if the diameter and pressure P of the through hole 6 are the same as in the case of FIG. You can increase your sexuality.
