Description

Manufacturing method of accessory hair strap {Accessory Band}

The present invention relates to an accessory hair strap for tying up the hair, and more particularly, the connection work of the band and the coupler having shrinkage elasticity and the butt connection operation of both ends of the band are made at the same time through the injection molding process for the attachment The present invention relates to a method for manufacturing an accessory hair strap.

Accessory hair straps are made by connecting both ends of a band having elasticity such as rubber bands (also known as straps and rubber bands, hereinafter referred to as bands) with a knot to form a ring, and hanging a ornament on one side of the band to bundle hair. It is to make the accessory function together with the function.

When the decoration is suspended on the band constituting the accessory hair strap, a 'U'-shaped ring having a flange is provided at both ends to insert a portion of the band in the groove, and then, the base plate is adhered to the upper part, and the upper plate is decorated. It is common to attach it, and sometimes the decoration is attached directly without the base plate.

However, in this case, the loop is free to move from the band, and the knots are exposed to the outside, so that the most important aesthetics of the accessory functions are deteriorated. When a tensile force is applied to the ring and the decoration was broken there was a problem.

As another example, there may be a case in which through holes are formed on both sides of a ring body having a decorative coupling surface on one side, and filled with an adhesive, and then both ends of the band are inserted and attached to form a ring, and then a decoration is attached to the adhesive surface.

However, in this case, it is difficult to insert both ends of the flexible band into the inside of the through-hole filled with the adhesive, and the workability is inferior.In addition, after the insertion, both ends of the band are completely attached. Because it has to be a long time, productivity decreases, such as taking a long time, which increases the cost of the product, as well as the defect that the attached band easily falls off, and due to the characteristics of the product where the tensile force is continuously applied, the durability is short due to the weak adhesive part. There is this. And this also has a problem that the phenomenon of falling rings and decorations.

In addition, in the conventional hair straps, there is a type in which a metal plate is rolled around the end in order to connect both ends of the band, and the end is closed by a jig and pressed and fixed to both ends of the band, but the metal plate itself is cold and hard. Not only can the texture be felt, but the sharp edges often result in scratches on the skin.

The present invention has been devised to solve the above-mentioned disadvantages, the object of which is the connection operation of the two ends of the band in the injection process for manufacturing the coupling for the decorative attachment to the band and the connection of the band and the coupler The present invention provides a method of manufacturing a robust, beautiful and safe accessory hair strap while being able to manufacture it quickly and easily without an adhesive by making it simultaneously in one process.

The present invention headband manufacturing method for achieving the above object,

In manufacturing an accessory hair strap having a band having a contractile elasticity and a coupler while being connected to the band,

The first and second molds are formed on the facing surface, and include first and second molds formed by forming a band through groove penetrating the coupler forming groove and the coupler forming groove and injecting resin into the coupler forming groove. Install it,

After connecting the both ends of the band in the open state of the first and second molds, the connecting portion is positioned in the coupling hole forming groove and exposed to the band through groove, and then the first and second molds are joined together. After injecting the resin into the coupling hole forming groove by operating the injection machine is cooled for a certain period of time after the mold opening is characterized in that the connection between the coupler and the band and both ends of the band is made at the same time during the injection process of the coupler.

The accessory hair strap of the present invention is connected to the band integrally by the injection molding and the both ends of the band is also integrally connected at the same time, the connection process of the band and the coupling in one injection process for the manufacture of the coupling Both ends of the band and the connection at the same time can be done quickly and easily, productivity is improved and you can get a solid product, as well as there is no defect. And since the connection part of the band is not exposed to the outside, there is an advantage that can achieve a clean and simple product.

In addition, metal clips or iron pins for connecting both ends of the band of the head strap are integrally integrated inside the joint molding so that they are never exposed to the outside and the shape of the joint itself is smooth and rounded. Likewise, the phenomenon of damaging the user's skin has the advantage of never occurring safety.

Figure 2 is a manufacturing process of the accessory hair strap according to the present invention.
Figure 3 is a band and coupler assembly state of the accessory hair strap according to the invention.
Figure 4 is a decorative attachment state of the accessory hair strap according to the present invention.

Hereinafter, with reference to the accompanying drawings, the structure of the accessory hair strap of the present invention will be described in detail.

As shown in FIG. 1, the accessory hair strap 10 of the present invention is connected to both ends of the band 10 to form a ring structure, the ornament 40, and the base plate 30 for attaching the ornament and the base plate. Composed of a coupler 20 for coupling the 30 and the band 10.

The band 10 is made of elastic material, such as a rubber band, and is integrally connected to the connecting portion and the coupling sphere 20 connected to both ends of the band 10 butt when manufacturing the coupling sphere 20.

That is, when injection molding the injection hole 20, the connection portion 12 of both ends of the band 10 is placed in the fitting hole 52 of the first and second molds 50a and 50b to be injected during injection molding. Molding treatment is performed integrally by the resin to be used.

When looking at the structure of the coupling tool mold to support this, as shown in Figure 2 the first and second molds 50a, 50b of the mating portion formed in the coupling hole forming groove 52 and the coupling hole forming groove 52 Band through grooves 54 are formed therethrough. Particularly, the coupling hole forming groove 52 formed in the first and second molds 50a and 50b is bisected into the coupling tool 20 in half to the first and second molds 50a and 50b, respectively. Is formed, the band through groove 54 toward the center of the coupler forming groove 52 is formed on both sides.

Of course, the general injection apparatuses for forming the first and second molds 50a and 50b are installed, including the gate 56 for injecting resin into the coupler forming groove 52 which is basically configured in the injection mold. do.

Looking at the process of manufacturing the band 10 in the state equipped with such an injection machine as follows.

First, as shown in FIG. 2, both ends of the band 10 are tied to form a knot 14, or both ends are wound with a tape 16 wrapped around them, or both ends are bent iron pins 18. Force the two ends of the band (10) to the both ends of the force), or insert both ends of the band (10) in the inside of the curled metal plate, and then twist both ends of the metal plate with a jig to press the both ends of the band Temporarily connect both ends of the band 10 by way.

In addition, as shown in FIG. 2A, both ends 12 of the band 10 are connected to the first and second molds 50a and 50b in a state in which the first and second molds 50a and 50b are opened. The band 10 is inserted into the band through groove 54 formed at both sides, while being positioned at the center of the coupling hole forming groove 52 of the first and second molds 50a as shown in FIG. ) 50b is molded and resin is injected into the coupler forming groove 52 as shown in FIG.

Since the band 10 placed in the band through groove 54 by the combination of the first and second molds 50a and 50b is subjected to strong pressure and is in a watertight state, the injected resin does not flow out.

When the resin is sufficiently cured after a predetermined time, the first and second molds 50a and 50b are opened as shown in FIG. 2D, and the band 10 and the coupling tool 20 are removed from the mold. The accessory band 10 in which the sphere 20 and the band 10 are integrated is manufactured. That is, the connection work between the band 10 and the coupler 20 and both ends of the band 10 are simultaneously performed by one coupling tool 20 injection process.

In particular, a knot 14 formed by tying both ends of the band 10, an adhesive tape 16 which is wound around both ends of the band and wound around the band 10, or iron pins 18 that are forcibly stuck and connected to both ends of the band 10 are connected. ), The connecting portion 12 is connected to the center of the coupling sphere 20 by rolling a metal plate around the band 10 in a state in which both ends of the band 10 are rolled around, and pressing the pins at both ends of the band. Since it is located inside the iron pin 18, knot 14, the metal plate (clip), etc. in the inside of the cured resin is to act as a locking step. Therefore, even if the band 10 is strongly pulled to both sides around the coupler 20, the band 10 is not separated or detached from the coupler 20 to achieve a rigid coupling state.

Attaching the decoration to the coupler 20 manufactured in this way, the accessory hair strap 10 is completed.

When the decoration is attached to form a plane on one side of the coupler 20 can be attached to the decoration via an adhesive.

As another method, in the structure for attaching the decoration 40 to the band 10 as shown in Fig. 1, 3, 4, the flange 22 is formed around the upper end of the coupling hole 20, the coupling It is provided with a base plate 30, which forms an assembling hole 32 through which the sphere 20 is inserted and formed therein, and a locking step step 34 on which the flange 22 of the coupler 20 is seated. Assembling the band 10 through the opening of the upper side and both sides of the coupler 20, and inserts the coupler 20 together with the band 10 into the assembly hole 32 of the base plate 30 After the flange 22 of the sphere is engaged with the latching step 34 of the base plate 30, it is completed by attaching a decoration 40 to the upper surface of the base plate 30.

At this time, if the band 10 is interfered with the inner end of the assembly hole 32 after the assembly of the band 10 and the coupling hole 20, the band 10 may be damaged due to frequent use and may be easily broken. Therefore, in order to prevent this, as shown in FIGS. 1, 3, and 4 to form a band exposure groove 36 in the inner end portion of the assembly hole 32 corresponding to the band 10 to remove the contact factor with the band 10. It may be. In some cases, the exposed grooves 28 may be formed in both lower portions of the coupler 20.
