Abstract

본 발명은 가죽시트와 합성수지로 이루어진 본체 사이의 경계면이 외관에 나타나지 않는 케이스부품을 성형하며, 성형불량이 일어나는 것을 방지하기 위한 사출성형금형을 제공하는 것을 목적으로 한다.An object of the present invention is to provide an injection molding mold for molding a case part in which the interface between the leather sheet and the main body made of synthetic resin does not appear in appearance and preventing molding defects from occurring.

본 발명의 사출성형금형은 가죽시트로 이루어진 표면을 갖는 성형부품을 성형하기 위하여, 제1금형과 제2금형을 구비한다. 제1금형은 성형부품의 외면과 대응하는 형상이 형성되어 있으며, 가죽시트가 제자리에 위치하도록 하기 위한 위치설정수단을 갖춘 캐비티블록을 가진다. 제2금형은 성형부품의 내면을 형성하기 위한 코어블록을 가진다. 제1금형의 캐비티블록과 제2금형의 코어블록 사이에는 캐비티공간이 형성된다. 사출성형금형은 가죽시트의 가장자리가 상기 캐비티공간 내로 변형하게 하기 위한 수단을 더 구비한다.The injection molding mold of the present invention includes a first mold and a second mold for molding a molded part having a surface made of a leather sheet. The first mold has a shape corresponding to the outer surface of the molded part, and has a cavity block having positioning means for positioning the leather seat in place. The second mold has a core block for forming the inner surface of the molded part. A cavity space is formed between the cavity block of the first mold and the core block of the second mold. The injection molding mold further comprises means for causing the edge of the leather seat to deform into the cavity space.
