この考案は、オープンテープリールに係り、こ
れの上下のフランジ外表面に入れられるべきサイ
ド表示に特徴を有する。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an open tape reel, and is characterized by side markings to be placed on the outer surfaces of the upper and lower flanges of the open tape reel.

た。
This type of open tape reel has side markings (AB side markings) on the top and bottom outer surfaces, but conventional side markings were placed in the center of the flange or in areas near the outer periphery that did not touch the outer periphery edge.

てゆく形態がとられていた。 In addition, this type of open tape reel has a pair of upper and lower reel structures 8a and 8b as shown in FIG.
When injection molding the reel components 8a and 8b, the injection gate for the plastic material is generally set at the center of the reel, and the raw material is press-fitted from the hub to the flange. It took the form of
かかる従来形態では、第１にサイド表示の形成

In this conventional form, firstly, there is a problem with the formation position of the side display, and it is difficult to find the side display with the hand holding the reel in a dark place. It was also inconvenient for blind people.

けが発生し、このガス焼けが進行すると成形後の
フランジ外周縁にバリが出る。 Second, when using conventional injection molding, the air in the molding space in the mold and the gas generated from the plastic material are condensed at high pressure at the outer peripheral edge of the flange molding space and combusted, causing the gas to flow inside the mold. Burning occurs, and as this gas burn progresses, burrs appear on the outer peripheral edge of the flange after forming.

全体の交換が必要であつた。 When the occurrence of burrs becomes severe, a mold repair process is performed to polish the parting surface of the mold and remove the gas burnt part, but if this mold repair is repeated, the shape and thickness of the outer periphery of the flange will change. (gradually becoming thinner) and the entire mold needed to be replaced within a relatively short period of time.

得ることを第２の目的とするものである。 The present invention has been proposed in order to eliminate such conventional problems, and aims to make it possible to find the side markings 11a and 11b that should be provided on the outer surfaces of the upper and lower flanges 6 and 7 very easily even by groping. The first purpose. A second object of the present invention is to obtain an open tape reel that can extend the life of the mold by improving the way the side indicators 11a and 11b are inserted.

As shown in the figure, in an open tape reel having flanges 6 and 7 on the upper and lower sides of a hub 1, the outer circumference of each flange 6 and 7 is placed on the outer surface of the outer circumference end 10 which becomes the final filling part of the molding resin. Side display 11a, 11b hanging on the edge
It is characterized in that it is formed into an uneven shape by the mold insert 14.

1 and 2 show a typical example of an open tape reel according to the present invention, which has a hub 1 for tape winding and a center hole 2 for positioning.
A drive pin hole 3 is provided vertically through the hub 1, and a tape insertion hole 5 having a tape end locking and fixing slit 4 is formed in a recessed manner, and tape protection flanges 6, 7 are inserted from the upper and lower ends of the hub 1. It has a structure in which it is connected to the outer periphery.

You can get it by twisting it. In each of the upper and lower flanges 6 and 7, three fan-shaped holes 9 are provided for monitoring the amount of tape and for reducing weight.

Side display 11 that hangs over the outer peripheral edge of the flange at 0
a and 11b are integrally molded in an uneven shape. The side indicators 11a and 11b in the illustrated example are arranged at locations corresponding to the circumferential center of each punch hole 9 in the flange outer peripheral end 10, and each has a shape with one recess on the upper flange 6 side. The lower flange 7 side has two recesses. Each side display 11a, 11b
The formation position is where the aforementioned gas burns and weld marks are most likely to occur during molding.

In this case, a mold insert 14 is separately assembled to a portion of the flange molding space 15 constituted by the upper and lower molds 12 and 13 that will be the final resin filling part, and molding is performed using the mold insert 14.
In other words, each of the side markings 11a, 11b is formed at a portion on the outer peripheral edge of the outer surface of the upper and lower flanges 6, 7, which is also formed at a circumferentially central portion of the outer periphery of each punch hole 9 in the figure.

なる。 During injection molding, plastic material is injected through a gate set near the center of the mold and flows from around the punch hole 9 into the flange forming space 15. At this time, the gas sealed in the molding space 15 is condensed near the mold insert 14, and the gas burnt of the mold is concentrated on the mold insert 14. Therefore, upper and lower molds 1
Leave 2 and 13 as they are, and replace mold insert 1 as necessary.
Only 4 will be replaced. In the open tape reel thus obtained, the recessed portions of each side display 11a, 11b are preferably filled with luminous paint 16 as shown in FIG. In such cases, the presence of this luminous paint 16 makes the side display 11
a and 11b can be easily seen even in a dark place, and it is also possible to clearly check whether the reel is rotating during use or whether the rotation speed is appropriate.

Make it a large one that exceeds 0, and display this side display 11
A and 11b are integrally formed with numbers 1 and 2 in an embossed manner. Of course, the side displays 11a and 11b may be formed integrally with the letters A and B in embossed form.

As described above, according to the present invention, the side markings 11a, 11b hanging on the outer peripheral edges of the upper and lower flanges 6, 7 are placed on the outer surface of the outer peripheral end portion 10, which is the final filling part of the molding resin. Since the mold insert 14 is formed into a concave and convex shape, by sliding the hand holding the open tape reel along the outer periphery of each flange 6, 7, the side displays 11a, 11b can be easily found even if it feels like groping. It is easy to use. Moreover, during molding, the gas in the molding space 15 can be condensed in the area where the mold insert 14 is present, and gas burns can be concentrated there, so that the life of the main mold can be extended by replacing only the mold insert 14. It has the advantage of being able to
