Description

The forming process of tooth brush formed tooth brush hair pieces}

The present invention relates to a toothbrush molding method associated with the present invention Utility Model Nos. 20-1999-8238 and 20-2000-8396, more specifically, to the toothbrush bar by banding the toothpiece inserted with a leaf spring By attaching to the present invention, it is possible to mass-produce high-quality dental hairpieces in a short time, and thereby to a molding method of a toothbrush which can minimize the production cost of the dental hairpieces.

In recent years, the inventors of the Japanese Utility Model Application Nos. 20-1999-8238 and 20-2000-8396 have devised a toothbrush that can densify or space the hairs to facilitate the washing and drying of the hairs. A toothed assembly which is bent by inserting a plurality of toothed pieces into the leaf spring is mounted at the tip of the toothbrush, and an operation plate is mounted on one side of the toothbrush to allow the toothpiece assembly to be pulled out.

In the case of manufacturing the toothbrush formed as described above, the densely-formed toothpiece forming mold with a thin partition is compacted and then molded and molded, but the synthetic resin inserted into the mold is leaked to the outside of the mold, whereby each toothpiece is pressed to generate a large amount of defective products. There is a closed end of the back, and in recent years, the toothed pieces with the fitting holes are individually molded and inserted into the leaf springs, but this is not only inefficient due to the large amount of work time, but also causes a cost increase. Problems such as this occur.

Therefore, there is a tooth piece molding apparatus (Patent Application No. 10-2001-0060083) invented by the present inventors to solve the above problems, the present invention relates to a method for molding a toothbrush molded toothbrush using the device. will be.

The tooth piece forming chamber 101-1 in which the plurality of tooth hole forming pins 101-3 are formed inside the upper mold 101 mounted to the left and right sides is molded at a predetermined interval, and the lower part of the upper mold 101 is formed. In the center, the leaf spring (2) is mounted to allow the densification and separation of the tooth piece (1). Is fitted with a longitudinal fitting groove 101-4, and inserted into a magnet 101-5 and a plate spring fixing hole that adsorbs the leaf spring 2 between each of the toothpiece forming chambers 101-1. And a locking pin 101-6 for fixing the leaf spring 2, and the upper outer surface of the lower mold 102 is opposed to the tooth piece forming chamber 101-1 of the upper mold 101. In the conventional toothbrush molding method using the toothpaste molding apparatus 100 in which the toothpaste molding chamber 102-1 and the synthetic resin inflow passage 102-2 are formed, the present invention is a leaf spring as shown in FIG. A bending step (S1) of banding both ends of the leaf spring (2) by dense each of the plurality of tooth pieces (1) inserted at (2) at predetermined intervals on both sides; Cutting step (S2) for cutting the intermediate portion of the leaf spring (2) is bent at both ends with a cutter (10); Toothbrush piece forming step (S3) of inserting the toothbrush piece (1) inserted into the banded leaf spring (2) in the toothbrush bar forming apparatus 20 of a predetermined shape and forming the toothbrush bar (3) to the bottom of the toothbrush piece (1) and ; An operation plate mounting step (S4) for mounting an operation plate 4 for moving the toothed piece 1 on one side of the toothbrush stand 3 formed above; It is characterized in that it consists of a combination of planting step (S5) to plant the pulp by using the hair removal device 30 in the toothed piece (1) of the toothbrush stand (3) on which the operating plate (4) is mounted.

In the above, the tooth spring piece 1 is inserted into the leaf spring (2) without the cutting step (S2) through the tooth shaping device 100, both ends are separately injection-molded, toothbrush forming step (S3), banding It may be formed of a toothbrush through the step (S1), operating plate mounting step (S4) and planting step (S5).

Reference numeral 100 in the drawings is a tooth piece molding apparatus.

As described above, the present invention has a synthetic resin inflow path of the tooth shaping device (A) (Patent Application No. 10-2001-0060083) formed of the upper mold 101 and the lower mold 102 as shown in FIG. 2A or 2B. When the synthetic resin solution is introduced into the 102-2), the synthetic resin solution is introduced into the synthetic resin solution into the pulp piece forming chambers 101-1 and 102-1 of the upper mold 101 and the lower mold 102, and the fitting groove 101-4 is provided. In the outer periphery of the leaf spring (2) inserted into the plurality of tooth pieces (1-3) and the operating plate guide path (1-2) is formed at predetermined intervals. In the above, the tooth piece 1 is the upper mold (1-4) due to the difference in the width of the upper mold 101, the tooth mold forming chamber 101-1 and the lower mold 102, the tooth mold forming chamber 102-1. The width of the lower part of the toothpiece (1-5) is molded differently. In addition, the plurality of toothpieces 1 inserted into the leaf spring 2 are dense and spaced apart due to the smooth outer surface of the leaf spring 2.

When the plurality of tooth pieces 1 are inserted into the leaf springs 2, which are divided into two sides based on the center, and the injection molding is performed, both sides of the tooth pieces 1 are spaced at a predetermined interval as shown in FIG. 3. If the same force is given due to the difference in width between the upper part of the tooth piece (1-4) and the lower part of the tooth piece (1-5), the width of the upper part of the upper part (1-4) is wider than that of the upper part (1-4). Narrow toothpiece lower portion (1-5) is the curvature becomes large, so the leaf spring (2) is bent at a predetermined interval.

The plate spring (2) and the toothed piece (1) undergoing the bending step (S1) are cut through the cutting machine 10 as shown in Figure 4, the middle portion of the leaf spring (2) is cut into two, separated a plurality of The leaf spring 2 and the tooth piece 1 are inserted into the toothbrush bar forming apparatus 20 in which the toothbrush bar shaping chamber 20-1 of a predetermined shape is formed as shown in FIG. 5, and the inside of the toothbrush bar shaping chamber 20-1. It is injection molded integrally with the toothbrush bar 3 by the synthetic resin introduced into. On one side of the toothbrush bar (3) in which the leaf spring (2) and the toothed piece (1) is formed, an operating plate (4) capable of densifying or spaced apart the toothed piece (1) is mounted as shown in FIG. (4) is mounted through the hair removal step (S5) for implanting the hair 5 in the pulp hole (1-3) as shown in Figure 7a or 7b through the conventional hair removal device (30). Is completed.

And another embodiment of the present invention, as shown in Figure 8a or 8b through the tooth piece forming apparatus 100, both ends of the tooth spring piece (1) is inserted into the leaf spring (2) only to one side is not largely divided. After injection molding, the tooth spring 1 into which the leaf spring 2 is inserted is inserted into the toothbrush bar forming apparatus 20 to mold the toothbrush bar 3, and the tooth spring piece 1 is already compacted to form the leaf spring 2 After going through the bending step (S1) of bending), the operating plate (4) is mounted on the toothbrush stand (3), the toothed plate (1) on which the operating plate (4) is mounted, It is completed by planting into the pores 1-3.

As seen from the above, the present invention minimizes the production process by injection molding the toothed piece 1 in a state in which the leaf spring 2 is inserted, the upper part of the tooth piece 1-4 and the lower part of the tooth piece 1-5. Due to the difference in the width of the banding by the compact without a separate banding device is possible, thereby maximizing the efficiency of the work, it is possible to minimize the production cost.

In this way, the present invention is banded to the toothbrush bar (3) by bending the injection molded toothpiece (1) through the toothbrush molding apparatus (A), to form the operating plate (4) and the bristles (5) on the toothbrush bar (3). By not only shortening the production process, but also maximizing the efficiency of the work, it is effective in mass production of high quality products by minimizing defective products and reducing the production cost through injection molding.
