本発明は軟質合成樹脂製筒材相互の溶着方法と
これに使用する溶着用金型に関し、筒部材相互の
溶着が、単一溶着工程で確実に為し得る溶着方法
と金型を提供することを目的としている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for welding cylindrical materials made of soft synthetic resin to each other and a welding mold used therefor, and a welding method that can reliably weld cylindrical members to each other in a single welding process. The purpose is to provide molds and molds.

不体裁となる。 Traditionally, cylindrical members are welded together by pressing the overlapping peripheral parts of the parts to be welded several times with a mold of a predetermined length with the welded parts partially overlapping, or by using a split mold. I'm doing it by whatever means I can. but,
In the former method, continuous peripheral edge portions must be welded several times, resulting in a large number of welding steps and poor work efficiency. In addition, the latter method results in incomplete welding of the abutting portions of the split molds, making it impossible to apply to items such as gloves that require liquid-tightness, and the split line being exposed, resulting in an unsightly appearance.

い。 The method of the present invention solves the above-mentioned conventional drawbacks, and in welding cylindrical members made of soft synthetic resin to each other, a hollow lower die in which the lower welding blade part is truncated and conical is provided with openings at both ends to be welded. After capping the cylindrical member from one open end and making the periphery of the other open end face the truncated cone-shaped slope, the other cylindrical member to be welded is placed into the hollow part of the lower mold, and one end of the cylindrical member is capped. Turn the opening periphery over and overlap it on the periphery of the cylindrical member which has been made to face the surface, and then use an upper mold having an upper welding blade part with an inner surface tapered corresponding to the truncated conical lower welding blade part, and then apply the overlapping part to the cylindrical member. It is characterized by being welded together. Incidentally, the overlap may be such that either side is on top.

うな場合である。 The welding of the soft synthetic resin cylindrical members to be welded together in the above method is, for example, when the transparent arm part of a laundry glove and the glove part are welded together as shown in FIG.
次に上記方法に用いる溶着用金型を、図示例に
おいて詳述する。 Next, the welding mold used in the above method will be described in detail with reference to illustrated examples.

The lower mold 1 has a lower welding blade 5 removably fixed to a hollow cylindrical base 3 with a screw 6, leaving a peripheral edge 4 at the upper end. has been done. The lower welding blade 5 has a welding surface formed with unevenness 7 and a truncated cone-shaped slope, and a through hole 8 is bored in the body of the hollow cylindrical base 3.
上型２は、下型１の溶着面に対応するテーパ形
内面の上溶着刃９を具備し、天部には貫通気孔１
０が穿設されている。 The upper mold 2 has an upper welding blade 9 on the tapered inner surface corresponding to the welding surface of the lower mold 1, and has through holes 1 in the top part.
0 is provided.
これら上下の金型は、従来と同様に高周波溶着

着ニする場合を図解説明する。 These upper and lower molds are used by setting them in a high-frequency welding machine so that the upper mold moves up and down, as in the past.Illustrated explanation of the case in which these molds are used to weld the laundry gloves shown in Figure 4. do.
まず下型１に透明腕部分となる筒部材イを被冠
して、一方の開口端を下溶着刃の上縁に一致する
よう覆う（第３図Ａ）。 First, a cylindrical member 2, which will become a transparent arm portion, is placed on the lower mold 1, and one open end thereof is covered so as to coincide with the upper edge of the lower welding blade (FIG. 3A).
次に手袋ロを、手挿入口ハを上方に向けて下型

明腕部の開口端縁に重ねる（第３図Ｂ）。 Next, hang the glove (2) into the hollow part of the lower mold (1) with the hand insertion port (C) facing upward, and fold back the periphery of the hand insertion port (C) outward, so that the edge can be seen through the transparent arm portion. It overlaps the opening edge of the transparent arm so as to match the lower edge of the lower welding blade (FIG. 3B).
最後に上型２を下降させて、透明腕部分となる
筒部材と手袋ロの手挿入口ハ周縁との重なり部分
を、下溶着刃と上溶着刃の間に挾み、該溶着部分
全周を一度に溶着する（第３図Ｃ）。 Finally, the upper mold 2 is lowered, and the overlapping part of the cylindrical member that will become the transparent arm part and the periphery of the hand insertion opening of the glove bottom is sandwiched between the lower welding blade and the upper welding blade, and the entire circumference of the welded part is (Fig. 3C).
尚、上下型を閉じた際に型内に密封される空気

気孔から逃出させる。 Note that the air sealed in the mold when the upper and lower molds are closed is allowed to escape through the through holes and through holes provided in each of the upper and lower molds.

型代も安い。 As described above, one of the upper and lower molds is hollow, and the welding surface is a truncated pyramidal slope (truncated pyramid or truncated cone), one of the cylindrical members to be welded is placed over the lower mold, and the other is By inserting the cylindrical member into the hollow and partially turning it over, an overlapping portion to be welded to the periphery of the upper end of the lower mold is formed. This overlapping part is exposed without intervening within the operating range of the upper mold, so if the upper mold corresponding to the overlapping part is closed, the entire circumference will be welded in a liquid-tight manner in one welding operation, and the welding Work efficiency is significantly improved. Furthermore, the mold used in the method of the present invention has a very simple structure, comprising a truncated cone-shaped welding blade and a corresponding welding blade, so the mold cost is lower than that of a split mold or the like.
しかも、溶着部分は全周が連続する一溶着であ
るから、ズレとか未溶着部による不体裁のないも
のとなり、製品外観を良好にする。 Moreover, since the welded part is a continuous weld all around the circumference, there is no unsightly appearance due to misalignment or unwelded parts, which improves the appearance of the product.
