인서트 매입형 사출금형의 인서트 받침구조Insert bearing structure of insert-molded injection mold

제1도는 본 고안의 적용위치를 나타낸 사출기에서 핵심부를 단면으로 표시한 정면도.Figure 1 is a front view showing the core portion in cross section in the injection machine showing the application position of the subject innovation.

제2도는 본 고안의 상세도.2 is a detailed view of the present invention.

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

1 : 금형 2 : 인서트1: mold 2: insert

3 : 받침3: stand

본 고안은 금속제 피봇 같은 매입부재 즉, 인서트를 갖는 성형물을 사출할 때 그 금형 내부에 투입인 상기 인서트를 금형조합시의 충격으로부터 보호하는 동시에 정확한 매입위치에 머물도록 받쳐주는 구조에 관한 것이다.The present invention relates to a structure for supporting the insert, such as a metal pivot, that is, the insert which is inserted into the mold when it is injected into the mold, while protecting the insert from the impact during the mold assembly and staying at the correct embedding position.

사출한 성형물의 물성에 비해 강도나 경도가 놓은 다른 재질로 제조한 피봇, 고정축 따위의 인서트를 금형내에 투입한 상태에서 가동 및 고정 금형을 조합하면, 이때의 충격으로 인하여 인서트가 일그러지는 일이 있고, 또는 인서트의 위치가 변동되는 수도 있다.When the movable and stationary molds are combined while the inserts, such as pivots and stationary shafts made of materials of different strength or hardness, are inserted into the molds, the inserts may be distorted due to the impact. Or the position of the insert may be varied.

이때문에 당초 의도했던 인서트 매입 성형물 금형도 손상되는 불이익을 보게 된다.Because of this, the original insert-molded molding die also suffers a disadvantage.

종래의 인서트 매입형 사출금형에서는 금형 조합시에 그 충격으로부터 인하여 인서트와 금형을 다같이 보호할 만한 아무런 구조도 갖추고 있지 않았다.Conventional insert recessed injection molds do not have any structure to protect both the insert and the mold due to the impact during the mold assembly.

이러한 실정하에서 본 고안이 나오게 된 것이다.Under these circumstances, the present invention came out.

즉, 본 고안은 금형(1)내에 인서트(2)를 탄력적으로 받쳐줄 받침(3)을 구비하고 있어 상기 종래와 같은 결점을 개선할 수가 있다.That is, the present invention is provided with a support (3) to elastically support the insert (2) in the mold (1) can improve the drawbacks as described above.

이 받침(3)은 발포수지, 고무 또는 발포고무 혹은 발포체는 아니더라도 고유의 탄성을 가진 것이면 어떤 재질로 하든지 가리지 않는데, 교환성, 경제성 등을 고려할 때에 바람직하기로는 합성수지나, 고무 구체적으로는 우레탄 고무를 들수가 있다.The support (3) is not foamed resin, rubber or foamed rubber or foam, but any material as long as it has inherent elasticity, it does not select any material, preferably in consideration of exchangeability, economical efficiency, synthetic resin, rubber, specifically, urethane rubber Can be raised.

또한, 이 받침(3)은 인서트(2)의 축선단면에 면접촉하도록, 아울러 인서트(2)와 축일치하도록 설치한다.Moreover, this support 3 is provided so that it may surface-contact with the axial end surface of the insert 2, and it is axially coincident with the insert 2. As shown in FIG.

이러한 탄성 받침구조(3)를 인서트 매입형 사출 금형에 적용하면, 가동 및 고정 금형(1)(4)이 조합될때 인서트(2)에 그 축방향으로 규정 압력(인서트의 길이와 양 금형 내면간 거리가 동일할때를 일컬음)이상 작용하면 규정압력을 초과한 압력분 만큼 탄성 받침(3)이 탄력적으로 수축되는 것에 의하여 상쇄되며, 바로 이같은 탄성받침(3)의 환충역활로써 인서트(2)와 금형(1)(4)이 보호되고 또한 이들간의 정확한 면접촉에 따라 바른위치, 바른 자세로서 인서트(2)는 성형물(5)상에 매입 고정될 수 있는 것이다.When such an elastic support structure 3 is applied to an insert-injection injection mold, when the movable and stationary molds 1 and 4 are combined, a predetermined pressure in the axial direction of the insert 2 (between the length of the insert and both mold inner surfaces) When the distance is the same), the elastic bearing (3) is offset by the elastic contraction by the amount of pressure exceeding the prescribed pressure, and this is the circular role of the elastic bearing (3) and the insert (2) and The mold 2 is protected and the insert 2 can be embedded and fixed on the molding 5 in the correct position and posture according to the correct surface contact therebetween.

Claims (1)

피봇, 고정축 따위의 인서트(2)에 매입형 사출금형에 있어서, 인서트(2)의 선단쪽에서 작용하는 금형(1)내에 인서트(2)의 축중심선상에 놓이게 탄성받침(3)을 설치하여서 된 인서트 매입형 사출 금형의 받침구조.In the injection molding mold embedded in the insert 2 such as the pivot and the fixed shaft, an elastic support 3 is provided in the mold 1 acting on the tip side of the insert 2 so as to lie on the axis center line of the insert 2. Structure of inserted insert recessed injection mold.
