Disclosed in the present specification relates to the provision of a molding apparatus that improves the internal cooling efficiency of a dust cap during an injection molding process of the dust cap. According to an embodiment of the present disclosure, a molding apparatus for molding a dust cap having a space formed between a side wall and an inner wall includes: a lower mold including a cooling unit in which a spiral passage is formed inside an outer wall surrounding a hollow and a cooling line inserted into the hollow in a cylindrical shape in which an inner space is formed; a first upper mold including a sliding core surrounding the cooling unit; and a second upper mold capable of going up and down from an upper portion of the first upper mold towards upper and lower portions and having an injection hole for injecting a raw material into a lower surface thereof. When the second upper mold is lowered and the raw material is injected toward the upper portion of the cooling unit, the raw material is injected between the sliding core and the cooling unit and between the cooling unit and the cooling line to form the dust cap.

    본 명세서에 개시된 내용은 더스트캡의 사출성형 과정에서 더스트캡의 내부 냉각효율을 개선하는 성형장치의 제공에 관한 것이다. 본 명세서에 개시된 내용의 일 실시예에 따르면, 측벽 및 내벽사이에 공간이 형성된 더스트캡을 성형하는 성형장치에 있어서, 성형장치는 중공을 둘러싼 외벽 내부에 나선형의 통로가 형성되는 냉각부 및 내부공간이 형성된 원기둥 형태로 상기 중공에 삽입되는 냉각라인을 포함하는 하부금형, 상기 냉각부를 둘러싸는 슬라이딩코어를 포함하는 제1상부금형 및 상기 제1상부금형의 상부에서 상하부를 향해 승강이 가능하고, 저면에 원료를 주입하는 주입구가 형성된 제2상부금형을 포함하고, 상기 제2상부금형이 하강하여 상기 원료가 상기 냉각부의 상부를 향해 주입되면 상기 슬라이딩코어 및 냉각부 사이와 상기 냉각부 및 냉각라인 사이에 상기 원료가 주입되어 상기 더스트캡이 성형된다.
