본 발명은 제1메니폴드와 제2메니폴드를 연결하여 길게 연장해야 하는 플라스틱제품 성형용 확장메니폴드에 있어서, 제1,2메니폴드의 수지통로입출구에 호퍼형 확장공과 대확장공을 형성하여 양단 내면이 테이퍼지고 중앙에 돌출링이 형성되며 양 확장공과 대확장공의 합한 길이보다 짧은 부시를 상기 대확장공과 확장공에 억지끼움이나 나사결합으로 대응되게 삽입하되, 제1메니폴드와 부시의 돌출링사이에 접시스프링에 의해 열팽창완충공간이 형성되게하고 상기 부시의 양단 내측에는 부시와 메니폴드사이에 열팽창완충공간이 형성되게한 것으로 구성되는 플라스틱스 성형용 열팽창완충 확장메니폴드에 관한 것이다.According to the present invention, in the expansion manifold for molding a plastic product, which must be extended by connecting the first and second manifolds, the inner surface of both ends is formed by forming a hopper type expansion hole and a large expansion hole at the resin passage inlet and outlet of the first and second manifolds. A protruding ring is formed at the center of the bearing, and a bush shorter than the combined lengths of both the expansion holes and the expansion holes is inserted into the expansion holes and the expansion holes correspondingly by interference fitting or screwing, and the plate is formed between the first manifold and the projection ring of the bush. It relates to a thermal expansion buffer expansion manifold for plastics molding that is formed by a spring to form a thermal expansion buffer space and a thermal expansion buffer space formed between the bush and the manifold inside both ends of the bush.
종래의 제1,2메니폴드를 연결시켜서 사용하는 확장메니폴드에 있어서는, 도1에서 도시된 바와 같이, 양측의 제1,2메니폴드의 수지통로로 흐르는 용융수지의 열에 의해 제1,2메니폴드의 중심(a)(b)이 일치되지 않고 틀어져서 양 메니폴드의 위치공차가 발생하게 되고 이렇게 되면 용융수지의 원활한 공급이 어렵게되고 그 수지의 흐름이 원활치 못하게 되면 플라스틱 제품의 원활한 성형이 이루어지지 못하는 결점이 있을 뿐 아니라 이로인해 연장하는 각개의 메니폴드들을 수시로 자주 교체해야하는 번거로움과 이로인해 제품의 원가상승 요인이 되는 결점이 있었다.In the conventional expansion manifold used by connecting the first and second manifolds, as shown in FIG. 1, the centers of the first and second manifolds are formed by the heat of the molten resin flowing through the resin passages of the first and second manifolds on both sides. a) (b) is misaligned and distorted, which causes position tolerance of both manifolds, which makes it difficult to supply molten resin smoothly, and when the flow of resin is not smooth, plastic molding of plastic products cannot be performed. Not only that, there was also the hassle of having to frequently replace each manifold that extends frequently, and this resulted in a defect in the cost of the product.
본원은 상기한 바와 같은 종래의 확장메니폴드의 결점을 해소하여 용융수지의 열에 의해서 메니폴드가 열팽창되는 현상을 완충시켜주는 작용을 하는 열팽창완충 확장메니폴드를 제공코저하는 것으로서, 제1메니폴드와 제2메니폴드의 수지통로입출구에 호퍼()형태의 확장공을 각각 천설하되, 제1,2메니폴드중 어느하나의 메니폴드에는 확장공 입구가 계단이 지도록 더 넓은 대확장공을 형성하고, 다른 하나의 메니폴드에는 확장공 내벽에 암나사를 형성한 다음, 양 단부의 내면에는 테이퍼면을 갖고 그 본체길이 전체는 상기 제1,2메니폴드의 확장공 및 대확장공 전체의 길이보다는 짧으며 그 외주면 중앙에는 상기 메니폴드의 대확장공의 내경과 일치되는 돌출링을 형성하고 그 본체 일측의 외주면에는 숫나사를 형성하거나 평면으로된 부시(Bush)를, 상기 어느 하나의 메니폴드에 형성된 대확장공과 확장공들에 대응되게 부시의 돌출링과 부시 양측을 삽입하되, 상기 대확장공의 계단과 부시의 돌출링사이에는 열팽창완충공간 형성용 접시스프링을 내장하고 사기 부시의 타측은 다른 하나의 메니폴드의 확장공에 억지끼움을 하거나 확장공의 암나사와 부시에 형성된 숫나사에 의해 나사결합하므로써, 상기 부시 본체의 양단과 상기 메니폴드의 확장공들의 테이퍼부의 경계선사이에 용융수지에 의해 발생되는 열팽창을 흡수, 완충시킬 수 있는 열팽창완충공간이 자연스럽게 형성되도록 구성한 것이다.The present invention is to provide a thermal expansion buffer expansion manifold to solve the drawbacks of the conventional expansion manifold as described above to buffer the phenomenon that the manifold thermal expansion by the heat of the molten resin, the first manifold and the second manifold Hopper at the resin channel entrance and exit of Each of the first and second manifolds is laid with a wider expansion hole, and a wider expansion hole is formed in the manifold of the first and second manifolds so that the entrance of the expansion hole is stepped, and another thread is formed in the inner wall of the expansion hole in the other manifold. Next, the inner surface of both ends has a tapered surface and the entire body length is shorter than the lengths of the entire expansion and expansion holes of the first and second manifolds, and the center of the outer circumference thereof coincides with the inner diameter of the large expansion hole of the manifold. Form a protruding ring and insert a male or flat bush on the outer circumferential surface of one side of the main body, and insert the protruding ring of the bush and both sides of the bush so as to correspond to the large expansion holes and the expansion holes formed in the manifold. A built-in dish spring for forming a thermal expansion buffer space is formed between the step of the large expansion hole and the protruding ring of the bush, and the other side of the fraudulent bush is the expansion hole of the other manifold. It is possible to absorb and buffer the thermal expansion caused by the molten resin between the both ends of the bush body and the boundary line of the tapered portion of the expansion holes of the manifold by forcibly fitting or screwing in by the female screw of the expansion hole and the male screw formed in the bush. The thermal expansion buffer space is configured to form naturally.

One side of the main body 4 'is first press-fitted, or the other side of the bush main body 4 is inserted into the expansion hole 7 of the other manifold 2 or the male screw 10 and the expansion hole 7 of the outer peripheral surface of the bush. One of the methods of inserting the other side first by screwing the female screw 8 is carried out, and between the protruding ring 4 and the step of the expansion hole 6, the plate spring 12 is inserted to insert a thermal expansion buffer space. In this case, since the length of the entire bush 11 is shorter than the total length of the expansion holes 6, 7 and the large expansion hole 9, the amount of the bush 11 is increased. However, thermal expansion buffer spaces 13 and 14 are generated between the inner line and the boundary line between the tapered portions 15 and 15 'of the expansion holes 6 and 7 of the first and second manifolds 1 and 2. Therefore, the thermal expansion buffering effect by the thermal expansion buffering space (13) (14) and the thermal expansion buffering space by the interposed spring (12) between the protruding ring (4) and the large expansion hole (9) of the first manifold (1) By the heat of the resin flowing through the bush 11 and the resin passages 5 and 5 'of the manifold 1 and 2, the manifolds 1 and 2 are not thermally expanded. (2) maintains a constant position at all times without the position tolerance of the centers (a) and (b), and the resin flows smoothly. The taper portions 15 and 15 'on both sides of the expansion holes 6 and 7 of the manifold 1 and 2 allow the resin to flow smoothly without being caught or delayed.
