成されたものがある。(Prior Art) A typical switching goggle body 13 is shown in FIG. 6 (only one side is shown), and a mold for injection molding this is shown in FIG. 7. As shown in the figure, the movable side mold 1 is made into a separate body, and the movable side columnar body 3 is formed by mirror-finishing the end surface 3a corresponding to the lens surface 14 of the goggle body 13, and the columnar body 3 is fitted into the movable side columnar body 3 to form an attachment/detachment eye. It has a cylindrical hollow body and the end edge 2a has a wedge-shaped cross section.
There is one that mainly consists of a two-part shrine with a movable mold body 2 formed in the mold body 2.

フェツジに形成する必要があった。Here, in order to give the lens surface (14) of the goggle body (13) a mirror finish and the other frames 1 and 15 a normal finish, it is necessary to 1. Separate molds at the boundary locations. ) Therefore, it was necessary to form the edge portion 2a into a knife edge as described above.
（発明が解決しようとする課題）
」二記従来の技術においては、以下のような課題が生じ
ていた。(Problems to be Solved by the Invention) 2. In the conventional technology, the following problems have occurred.
■ 端縁部２ａがナイフェツジでその先端２１）が可動
側柱状体３の端面３ａの周縁３ｈの高さと一致するとこ

において樹脂の流動圧をもろに受けて変形したり、ひど
い場合には破損したりすることもあった。また、このよ
うな端縁部２ａの変形によって所謂パリが発生して、不
良品産出の原因になっていた。■ The end edge 2a is a knife, and its tip 21) is located at a location that matches the height of the circumferential edge 3h of the end surface 3a of the movable columnar body 3, and it is difficult to make these heights match perfectly during mold manufacturing. Therefore, the end edge 2a is at its tip 2b.
In some cases, the resin was subjected to the flow pressure of the resin, resulting in deformation or, in severe cases, damage. In addition, such deformation of the edge portion 2a causes so-called cracks to occur, resulting in the production of defective products.
■ 所謂度付きゴーグルを成形する場合には、レンズの

ものとなる。■ When molding so-called prescription goggles, it is necessary to increase the thickness of the peripheral edge of the lens, and for this purpose, the movable side columnar body 3 is slightly erected in the movable side mold body 2 to thicken the edge. 2a may be made to slightly protrude into the goggle body molding chamber 10 to intentionally form a wedge-shaped groove 18.
If a foreign object remains in such a wedge-shaped groove 18, it is very difficult to remove it, narrowing the field of view and causing discomfort to the user.
■ 更に、上記楔状溝１８に防曇剤等の薬品が侵入した
場合や、フレーム部１５の開口部に開方向に大きな力が
働いた場合に、前記楔状溝１８の先端からクランクが発
生しやすい。Furthermore, if a chemical such as an anti-fogging agent enters the wedge-shaped groove 18, or if a large force is applied to the opening of the frame portion 15 in the opening direction, cranking is likely to occur from the tip of the wedge-shaped groove 18. .
本発明は、上記課題を解決し、金型の変形や破損を防止

品価値の高い製品を提供することを目的とする。The present invention solves the above problems, prevents deformation and breakage of the mold, and further improves its durability.The present invention also improves the product value of the goggle body, which is a molded product, by not forming wedge-shaped grooves. The aim is to provide high quality products.

ことである。(Means for Solving the Problems) In order to achieve the above object, the technical means adopted by the present invention is, as a first means, on the end surface 3a side of the movable side columnar body 3 of the movable side mold body 2. The cross-sectional shape of the end edge 2a around the movable mold body 2 is formed into a truncated wedge shape. This is because the columnar body 3 is placed seven times in advance in a state in which it projects upwardly beyond the tip 2h of the edge 2a.

１３に楔状溝１８が形成されることはない。(Function) In the first means, the end edge 2 of the movable mold body 2
The cross-sectional shape of a! ! Since the head is wedge-shaped, the edge portion 2a is relatively thick and has increased strength, and furthermore, the wedge-shaped groove 18 is not formed in the goggle body 13.

が樹脂の流動圧によっては変形し難い状況となる。Further, in the second means, since the peripheral edge 3h of the end surface 3a of the movable side columnar body 3 projects in advance beyond the tip 2b of the end edge portion 2a of the movable side mold body 2, the mold body 2 slightly Even if the tip 2b has a slight height difference due to manufacturing errors, the tip 2b will not protrude into the goggle body molding chamber 10. Therefore, the wedge-shaped groove 18 is not formed in the goggle body 13, and the tip 2h
However, depending on the flow pressure of the resin, it becomes difficult to deform.
（実施例） 以下、図に従い本発明に係る実施例について詳述する。(Example) Embodiments according to the present invention will be described in detail below with reference to the drawings.

(only one side) is formed. In addition, this goggle body 13
Depending on the shape of the side core 7 is not required (therefore,
In some cases, the angular pin 9 is not required.

The goggle body 13 is provided with columnar bodies 3 and 6 on each movable and fixed side, and the molds 1.4 on each side are constructed separately.
This is to make only the lens surface 14 smooth, and each end surface 3a, 6a of each side columnar body 3, 6 is mirror finished.

の原因となることがほとんどない。Of the injection mold constructed as described above, Figure 1 (
a) to FIG. 1(C) show a first embodiment, in which the movable side columnar body 3 and the molding chamber 10 are located in the upper part of the movable side mold body 2.
The cross-sectional shape of the portion sandwiched between the edges (edge portion 2a) is shaped like a truncated wedge. In this specification, the truncated wedge shape does not necessarily refer to the one shown in FIG.
As shown in Figure (C), the upper outer tip of the edge portion 2a may be rounded. In this case, first of all, it is relatively thicker than the conventional wedge-shaped end edge 2a,
The edge portion 2a is hardly deformed by the flow pressure of the resin, and a highly durable mold can be obtained. Second, when molding prescription goggles, in order to make the peripheral edge side of the lens surface 14 thicker, the columnar body 3 is slightly buried in the movable mold body 2 to intentionally form the groove 16. In some cases, the groove 16 is formed in the shape of a truncated wedge with a bottom surface 17 (see FIG. 4), so that foreign matter is less likely to remain therein, and furthermore, it hardly causes cracks.
また、第２図は第２実施例を示し、前記可動側柱状体３

することもない。Further, FIG. 2 shows a second embodiment, in which the movable columnar body 3
is attached so that the peripheral edge 3b of the end surface 3a thereof protrudes beyond the tip 2b of the end edge 2a of the movable mold body 2. In this case, even if there is a slight manufacturing error in the edge portion 2a, the tip 2b will not protrude into the molding chamber 10, so the edge portion 2a will not be deformed by the flow pressure of the resin. Further, the wedge-shaped groove 18 is not formed in the goggle body 13.
更に、第３図は第３実施例を示し、可動側柱状体３を図

が得られ、楔状溝１８は形成されない。Furthermore, FIG. 3 shows a third embodiment, in which the movable side columnar body 3 is molded to be thicker than the conventional one as shown in the figure, and the tip end 2b of the movable side mold body 2 is lowered to the illustrated position. Not only the lens surface 14 of the goggle body 13 but also the frame portion 1
5 is also formed from this columnar body 3. In this case as well, the same effects as in the second embodiment can be obtained, and the wedge-shaped groove 18 is not formed.

is provided, and a ring-shaped part 20 of different color is placed in this circumferential notch 19.
You can also install it.

に生産性がよくなる。(Effects of the Invention) According to the present invention, in both the first means and the second means, the wedge-shaped groove 18 is not formed in the goggle body 13, so that various inconveniences (foreign particles) caused by the wedge-shaped groove 18 can be avoided. (retention of water, generation of squeaks, etc.) are eliminated, and furthermore,
Since the edge portion 2a is not deformed or damaged by the flow pressure of the resin, there are almost no defective products produced, and the durability of the mold itself is further improved, resulting in extremely high productivity.
尚、度付きゴーグルを成形する際に、敢えて溝１６を形

ることができる。Incidentally, when molding prescription goggles, there are cases where the groove 16 is deliberately formed, but in the first means, in such a case, the groove 16 is formed in a truncated wedge shape having a bottom surface 17. Prescription goggles with high commercial value can be obtained because foreign substances are difficult to accumulate and hardly cause scratches.
