Description

[0001] EARTIP MANUFACTURING APPARATUS WITH DUAL SUPPORT [0002]

The present invention relates to an ear tip manufacturing apparatus having a double support, and more particularly, to an ear tip manufacturing apparatus having a double support capable of manufacturing an ear tip having a property of being slowly restored while having excellent elasticity.

Generally, eartips are inserted into the ear of a worker for the purpose of reducing the noise level in a place where a loud noise such as a factory or a business site is used, or used for listening to voice or music personally through a device such as a smart phone or MP3 The earphone is connected to the earphone for user's convenience and is used for the part contacting the ear.

As described above, since the ear tip is used in contact with the ear, the ear tip is made of a soft material to enhance the feeling of wearing. As a conventional technique, Korean Patent Registration No. 1323805 discloses a method of manufacturing an ear tip using a silicone material. However, in the case of manufacturing a ear tip using a silicone material as in the prior art, the thickness of the ear tip must be made thin or made low in order to enhance the wearer's feeling. Therefore, the eartip made of a silicone material can be comfortably worn, There is a disadvantage that the pressure is applied when inserting into the ear, and the degree of deformation is shaped, resulting in a problem that the degree of contact of the ear drops according to the size of the ear canal.

In addition, when manufacturing the ear tip using a material such as polyurethane, which is excellent in elasticity and slowly recovering property, there arises a difficult problem such as gas discharge in forming an extremely small ear tip to be inserted into a user's ear . In more detail, in general, when a product is manufactured from a material such as polyurethane, a gas outlet must be formed in the mold in order to remove gas generated during molding of polyurethane or the like. However, since the eartip is small enough to fit into the ear of a person, it is very difficult to form a gas outlet one by one in a small-shaped eartip mold, and even if a gas outlet is formed in each eartip shape, There arises a problem that unnecessary cost is incurred because the product must be removed one by one and the completeness of the product is lowered.

In addition, in the case of manufacturing an ear tip using a material such as silicon or polyurethane, it is necessary to end-treat the ear tip for removing the molded product. It takes time and effort to manually carry out the end treatment of the small ear tip In particular, in the case of producing an eartip with a non-uniform upper portion, there arises a problem that it is difficult to be manually handled.
