본 발명은 각종 음향기기용 이어폰에 덮어 씌우는 스폰지 덮개를 정확한 규격품으로 양산할 수 있게한 이어폰용 스폰지 덮개 제조 방법에 관한 것이다.The present invention relates to a method for producing a sponge cover for earphones that can mass-produce a sponge cover to cover the earphones for various acoustic devices to an accurate standard product.

각종 음향기기용 이어폰에 덮어 씌우는 스폰지 덮개는 스폰지 원재를 1개씩 절연선으로 절단 및 절삭 가공 제품하는 것이 알려져 있는 바, 본 발명은 이와같은 1개씩의 절단 및 절삭 가공 제품하는 방법을 지양해서 정확한 규격품을 양산할 수 있도록 발명한 것이다.It is known that the sponge cover which covers the earphones for various sound equipments is cut and cut products of the raw material of sponge by one insulation line, and the present invention avoids the method of cutting and cutting the pieces one by one. It is invented so that it can be done.

본 발명은 이어폰 본체가 감입될 요입부 여러개를 미리절단 형성한 스폰지 기재판과 덮개판부가될 스폰지 기재판을 겹쳐서 이를 가열 금형으로 절단과 용해 접착이 되도록 1회의 가공 동작으로 여러개의 제품을 양산할 수 있도록 발명한 것으로서 이를 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention superimposes the sponge base plate formed by cutting a plurality of concave inlet parts to be inserted into the earphone body and the sponge base plate to be a cover plate, and mass-produces several products in one processing operation to cut and dissolve and glue them with a heating mold. When the invention is described in detail based on the accompanying drawings as follows.

본 발명은 실시례에 있어 16개의 통공(2)를 스폰지 기재판(1)에 천공 배설한 것과 평판으로 된 스폰지 기재판(3)을 겹쳐서 통공(2)와 동일한 배설로 되는 금형 요입부(7)과 금형원테(6)을 각기 형성한 가열금형 기틀판(5)위에 재치하고 금형요입부(7)과 금형원테(6')를 각기 형성한 가열 금형기틀판(5')를 프레스 실린더(10)의 작동으로 하강 압압하므로서 스폰지 기재판(1), (3)은 금형요입부(7) 형태로 성형되면서 금형기틀판(5), (5')내에 장설된 전열선(8)에 의하여 적정열이 유지되는 금형원테(6), (6')가 서로 합치되면서 통공(2)주위를 원형으로 용해 절단함과 아울러 그 주위 언저리는 용착부(4)로서 용해 접착되어 제5도 표시와 같은 제품을 16개 제품하게 되는 것이다.According to the present invention, in the embodiment, the mold recess 7 which is formed by puncturing the sixteen through holes 2 on the sponge base plate 1 and overlaps the sponge base plate 3 made of a flat plate with the same excavation as the through holes 2 is provided. ) And the heated mold base plate 5 'on which the mold recess 7 and the mold circle 6' are formed, respectively, are placed on the heated mold base plate 5 on which the mold circle 6 is formed. 10, the sponge base plate (1), (3) is molded in the shape of the mold inlet portion (7) by pressing down by the operation of the heating element (8) installed in the mold base plate (5), (5 '). Mold elements (6) and (6 '), which maintain alignment, coincide with each other to melt and cut the periphery of the through hole (2) in a circular shape, and the edges around them are melted and bonded as the welding portion (4), as shown in FIG. You will have 16 products.

이와같이 본 발명은 여러개의 통공(2)를 미리 천설 형성한 스폰지 기재판(3)을 겹쳐서 통공(2)와 합치되는 배설을 한 가열형 금형원테(6), (6') 및 금형 요입부(7)이 형성된 프레스 금형으로 1회 가공에 16개 또는 그 이상의 양산 효과를 거두고 또한 정확한 규격품을 제품할 수 있게 되는 것이다.Thus, the present invention overlaps the sponge base plate 3 formed in advance through the formation of a plurality of through holes (2), the heating mold molds (6), (6 ') and excavation portion ( 7) is a press mold with 16 or more mass production effects in one process and accurate standard products.
