몰드 금형의 성형품 공기 주입구 밀폐장치Molded Product Air Inlet Sealing Device of Mold Mold

제1도는 본 고안의 사시도.1 is a perspective view of the present invention.

제2a도, 제2b도는 본 고안의 작동 단면도.2a, 2b is a cross-sectional view of the operation of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1, 2 : 금형 1', 2' : 성형홈1, 2: Mold 1 ', 2': Molding groove

1", 2" : 공기유입홈 101 : 스프링실1 ", 2": air inlet groove 101: spring chamber

102 : 안내구멍 3 : 작동구102: guide hole 3: operating port

4 : 스프링 5 : 고정판4: spring 5: fixing plate

본 고안은 금형 내의 재료를 압축공기압으로 팽출시켜 성형하는 몰드금형의 성형품 공기 주입구 밀폐 장치에 관한 것이다.The present invention relates to a molded article air inlet closure device of a mold mold for expanding and molding the material in the mold with compressed air pressure.

몰드 금형에 의하여 내부에 공기가 충입되게 성형품을 성형시키고자 할 때는 성형품이 냉각된 상태에서는 성형품의 공기 주입구도 냉각되어 붙지 않게 됨으로 이의 밀폐효율을 높이기 위해서는 성형품이 금형 내에서 성형됨과 동시 냉각되기 직전에 성형품의 공기 주입구를 밀폐시켜 줌이 바람직하다 하겠는데 아직까지 이에 만족할 만한 금형장치가 인출된 바 없어 내부에 공기를 충입 성형하는 몰드 금형의 성형품 제조에 많은 어려움이 따르게 되었다.When molding a molded product so that air is filled in by the mold die, the air inlet of the molded product is not cooled and adhered while the molded product is cooled. Therefore, in order to increase the sealing efficiency, the molded product is molded in the mold and simultaneously cooled. It is desirable to seal the air inlet of the molded article, but there is no mold device that satisfies this yet, so that a lot of difficulties have been made in the manufacture of the molded article of the mold mold filled with air therein.

본 고안은 이와 같은 결점을 해결하기 위하여 성형품이 냉각되기 직전에 성형품의 공기 주입구를 압압하여 간단히 밀폐시킬 수 있도록 한 매우 합리적인 구조의 몰드 금형의 성형품 공기 주입구 밀폐 장치를 안출하게 된 것인데 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve this drawback, the present invention has devised a device air inlet sealing device of a mold mold having a very reasonable structure that can be simply closed by pressing the air inlet of the molded part immediately before the molded part is cooled. When described in detail as follows.

성형홈(1')(2') 및 공기유입홈(1")(2")이 형성된 한쌍의 금형(1)(2)으로 하여 금형(1)(2)에는 공기 유입 구멍(201)을 형성한 것에 있어서, 금형(1)에는 공기 유입홈(1")과 관통되는 스프링실(101) 및 안내구멍(102)을형으로 뚫어서, 작동구(3)의 일부가 외방으로 노출되게 스프링(4)으로 탄력시켜 고정판(5)으로 고정시켜서 된 것이다.A pair of molds (1) and (2) formed with forming grooves (1 '), 2' and air inlet grooves (1 ", 2") are provided with air inlet holes (201) in the mold (1) (2). In the forming, the mold 1 has a spring chamber 101 and a guide hole 102 penetrating through the air inlet groove 1 ". Drilled into a mold, the part of the operating port (3) is to be fixed to the fixing plate (5) by elasticity with the spring (4) to be exposed to the outside.

미설명 부호 6은 압축공기주입판이고, 7은 압축공기에 의하여 튜우브상으로 성형되는 성형품이고, 7'은 성형품의 공기주입구이며, 8은 볼트이다.Reference numeral 6 denotes a compressed air injection plate, 7 is a molded product molded into a tubular shape by compressed air, 7 'is an air injection port of the molded product, and 8 is a bolt.

이와 같이 된 본 고안은 양 금형(1)(2)의 성형홈(1')(2') 내에다 성형 재료를 내입한 다음 금형(2)의 공기유입구멍(201)을 통하여 압축공기를 유입하여 튜우브형의 성형품(7)을 성형시키게 됨은 주지인바, 이의 몰드 성형 과정에서 내부에 공기를 충입시킨 성형품(7)을 성형코자 할 때는 본원은 외부에 노출된 작동구(3)의 단부를 제2도 (b)와 같이 압압하게 되면 금형(1) 내의 작동구(3)의 단부는 이동되어 공기 주입구(7')를 서로 압접시켜 밀폐시키게 되며 작동구(3)의 압압력을 해제하면 작동구(3)는 스프링(4)의 탄발력에 의하여 제2a도의 원상태로 복귀하게 되는 것이다.In this way, the present invention inserts the molding material into the forming grooves 1 'and 2' of both molds 1 and 2, and then introduces compressed air through the air inlet hole 201 of the mold 2. It is well known that the tubing-shaped molded product 7 is molded. In order to mold the molded product 7 filled with air in the mold molding process, the present application removes an end portion of the operation opening 3 exposed to the outside. When pressed as shown in (b) of FIG. 2, the ends of the actuating holes 3 in the mold 1 are moved to seal the air inlets 7 ′ by pressing them together. The sphere 3 is to be returned to the original state of FIG. 2a by the spring force of the spring 4.

이와 같은 본 고안은 금형(1)에다 직접 매우 합리적인 구조의 성형품(7)의 공기주입구(7')를 밀폐 시키는 밀폐장치를 구성하였으므로 공기주입구(7')의 밀폐붙량이 발생될 염려가 없음과 아울러 성형 작업의 능률을 향상시킬 수 있는 효과가 있다.The present invention has a sealing device that seals the air inlet 7 'of the molded article 7 having a very reasonable structure directly to the mold 1, so that there is no fear that the amount of airtight seal of the air inlet 7' will occur. In addition, there is an effect that can improve the efficiency of the molding operation.
