Description

부시 제품의 가황 성형 진공장치{vacuum apparatus vacuum for vulcanization form of bush goods}Vulcanization apparatus vacuum for vulcanization form of bush goods

본 발명은 자동차 등에 소요되는 고무 재질로 이루어지는 부시 등의 제품을 제작하기 위한 금형에 있어서, 금형에 투입되는 황이 포함된 생지 고무 원료에 열을 가하여 화학반응으로 블렉시블하게 되도록 부시 등을 제작하는 가류 사출 금형 장치에서, 사출 성형시 그 성형기의 런너에 공기가 들어가 불량이 발생하는 것을 방지하기 위한 장치에 관한 것이다The present invention is a mold for manufacturing a product such as a bush made of a rubber material used in automobiles, etc., to produce a bush or the like to be flexible by chemical reaction by applying heat to the raw material rubber material containing sulfur to be injected into the mold In a vulcanization injection mold apparatus, it relates to a device for preventing air from entering into the runner of the molding machine during injection molding and causing a defect.

종래의 경우, 생지 고무를 이용한 가류 금형 사출시, 공기가 사출 성형기의 캐비티에 들어가면 고무가 덜 채워져 불량이 발생한다In the conventional case, when vulcanizing mold injection using dough rubber, when air enters the cavity of the injection molding machine, the rubber is filled less and a defect occurs.

따라서 이를 방지하기 위해, 종래는 성형 장치의 박스 전체에서 진공을 걸어 공기를 뽑아내어 왔는데, 이 경우, 진공도가 높지 않으며 진공 효율이 떨어진다Therefore, in order to prevent this, conventionally, vacuum has been drawn out from the entire box of the molding apparatus, in which case the degree of vacuum is not high and the vacuum efficiency is inferior.

또한 그 진공을 위한 진공 설비의 부피가 크게 되고 부품도 많이 소요되는 단점이 있다.In addition, there is a disadvantage in that the volume of the vacuum equipment for the vacuum is increased and a lot of parts are required.

본 발명은 이를 해결하기 위하여 발명한 것으로, 사출 성형 장치의 런너에 공기를 뽑아 줄 수 있는 통로를 형성하여, 진공펌프와 연결하여 진공을 가해줄 수 있게 구성하여 부시 등의 불량률을 크게 줄이고, 진공 장치의 소형화, 경량화 및 설비 운용의 비용이 최소화하게 한 것이다The present invention has been invented to solve this problem, by forming a passage for drawing air to the runner of the injection molding apparatus, it is configured to connect to the vacuum pump to apply a vacuum to significantly reduce the failure rate of the bush, vacuum Minimization, weight reduction and cost of equipment operation are minimized.

본 발명은 부시 제품을 가황 성형으로 제작시 사용되는 금형의 구조에 있어서, 금형 내부의 런너판(1)의 런너(2)와 소통되게 공기 인출로를 형성하여, 런너판(1)의 외측에 형성시킨 연결통로(7)와 연결되게 구성한 것을 특징으로 하며, 상기한 인출로는, 런너(2)와 연결되는 공간(3)과, 공간(3)의 외측으로 연결되는 직선형의 통로(4)와, 통로(4)와 외측으로 연결되는 외측공간(5)과, 외측공간(5)과 직선으로 연결되는 도출로(6)로 이루어지며, 도출로(6)는 연결통로(7)와 연결되는 것을 특징으로 하며, 상기한 통로(4)는 3 개 형성되는 것을 특징으로 하며, 상기한 통로(4)와 도출로(6)는 직선으로 연결되는 것을 특징으로 하며, 상기한 연결통로(7)에는 진공 펌프(30)가 연결되는 것을 특징으로 하며, 상기한 인출로는 런너판(1)에서 좌우, 전후 대칭 구조로 형성하는 것을 특징으로 한다According to the present invention, in the structure of a mold used when manufacturing a bush product by vulcanization molding, an air outlet path is formed in communication with the runner 2 of the runner plate 1 inside the mold, and is formed outside the runner plate 1. It is characterized in that it is configured to be connected to the formed connecting passage (7), the draw path, the space (3) connected to the runner (2), the linear passage (4) connected to the outside of the space (3) And an outer space 5 connected to the outside of the passage 4 and a drawing passage 6 connected to the outer space 5 in a straight line, and the drawing passage 6 is connected to the connecting passage 7. Characterized in that, the passage 4 is characterized in that three is formed, characterized in that the passage 4 and the draw path 6 is connected in a straight line, the connection passage (7) ) Is characterized in that the vacuum pump 30 is connected, the drawer is formed in the left and right, front and rear symmetrical structure in the runner plate (1) It is characterized by

본 발명에 의하면, 성형장치의 런너에서 진공을 바로 가해 줄 수 있어, 그 진공 효율이 매우 우수하고, 진공을 위한 설비를 소형화할 수 있있으며, 아울러 그 운전 비용과 보수 유지 비용도 최소화할 수 있다According to the present invention, it is possible to directly apply a vacuum in the runner of the molding apparatus, and the vacuum efficiency is very excellent, and the equipment for the vacuum can be miniaturized, and the operation cost and the maintenance and maintenance cost can be minimized.

상기한 본 발명의 특징 외의 다른 특징 및 구성에 대하여 이하, 첨부 도면에 의거 추가로 상술한다Other features and configurations other than the features of the present invention described above will be further described below based on the accompanying drawings.

도 1 은 본 발명에 따라 금형의 런너에 공기 배출 통로를 형성시킨 것을 보여 주기 위한 도면이다1 is a view for showing that the air discharge passage is formed in the runner of the mold according to the present invention;

도시한 바와 같이, 런너판(1)에 런너(2)가 형성되어 있으면 이곳에서 외부로 향하는 위치에 공간(3)을 형성시킨다. 예를 들어 약 0.2mm 정도의 깊이로 납작하게 공간(3)이 형성되게 한다. 일정 면적을 갖는 공간으로 형성하는 이유는, 이 공간(3)으로 런너(2)에 잔류하는 잔류 공기가 충분히 모여 도출될 수 있게 하기 위한 것이다. 도면의 실시예에서는 사각 형상의 공간이 형성되게 하였다As shown in the figure, if the runner 2 is formed in the runner plate 1, the space 3 is formed in the position which faces to the outside from this. For example, the space 3 is formed flat to a depth of about 0.2 mm. The reason for forming into a space having a predetermined area is to allow the residual air remaining in the runner 2 to be sufficiently collected and drawn out in the space 3. In the example of the figure, a rectangular space is formed.

그리고 여기서 다시 외부로 연장되게 인출되는 인출 통로(4)를 여러 개 형성시켰다. 이 통로(4)의 깊이는 예를 들어, 약 0.5mm 정도로 한다. 그리고 다시, 다소 넓은 면적으로 이루어지는 외측공간(5)을 형성하였다. 외측 공간(5)도 일정한 면적으로 공간이 형성되게 한 이유는 상기한 공간(3)의 형성 이유와 동일하다. 이 외측공간(5)의 깊이는 예를 들어, 0.2mm 정도 깊이로 한다.Here, several withdrawal passages 4 are formed to be drawn out again to extend to the outside. The depth of the passage 4 is, for example, about 0.5 mm. And again, the outer space 5 which consists of a rather large area was formed. The reason why the outer space 5 is also formed in a constant area is the same as the reason for forming the space 3 described above. The outer space 5 has a depth of about 0.2 mm, for example.

상기한 공간(3)과 외측공간(5)이 없이 바로 공기를 뽑아내면 진공 부하가 많 이 걸리므로 바람직하지 못하다. 특히 런너(2)의 구조상 얕은 깊이로 공간을 만들기 때문에 공기의 도출로가 90도로 절곡되는 곳에서는 특히 진공을 위한 흡입 부하가 많이 걸리므로 이렇게 넓은 면적으로 공간(3)과 외측공간(5)을 형성시킨다It is not preferable to extract air immediately without the space 3 and the outer space 5 because a large vacuum load is required. In particular, since the space of the runner 2 makes a space with a shallow depth, the suction path for the vacuum is particularly high in a place where the air flow path is bent at 90 degrees, so that the space 3 and the outer space 5 are largely spaced. Forms

외측공간(5)에서는 다시, 직각으로 충분히 깊은 통로로 이루어지는 도출로(6)와 통하게 연결되고 최종 연결통로(7)와 직각으로 연결된다. 연결통로(7)는 하나 또는 2 개 이상 설치도 가능하며, 도시하지 않은 진공 펌프와 연결되어 캐비티 내에 들어 있는 공기를 빼어 준다In the outer space 5, again, it is connected to the lead-out passage 6 consisting of a sufficiently deep passage at right angles and connected to the final connection passage 7 at right angles. One or two or more connecting passages 7 may be installed, and are connected to a vacuum pump (not shown) to extract air from the cavity.

이와 같은 구성으로 좌우 대칭 및 상하 대칭으로 형성시킨다. 그러나 런너판(1)의 구조에 따라 대칭이 아닌 구조로 만들 수 있음은 물론이다In such a configuration, the left and right symmetry and the vertical symmetry are formed. However, according to the structure of the runner plate 1 can be made of a structure that is not symmetrical of course

도 2 는 도 1 의 우측면도이다 FIG. 2 is a right side view of FIG. 1. FIG.

도시한 바와 같이 공간(3), 통로(4), 외측공간(5), 도출로(6), 및 연결통로(7)의 깊이를 확인할 수 있다As shown, the depth of the space 3, the passage 4, the outer space 5, the draw passage 6, and the connection passage 7 can be confirmed.

도 3 은 참고로 성형 몰드 베이스 조립체의 상면을 도시한 것으로, 그 내부에 런너판(1)이 설치되어 있음을 보여준다. 런너(2)가 형성된 런너판(1) 주위에는 진공림(11)이 여러 층 빙 둘러 실링처리되어 외기와 공기 유통이 되지 않게 기밀 유지된다.3 shows the upper surface of the molded mold base assembly for reference, and shows that the runner plate 1 is installed therein. Around the runner plate 1 in which the runner 2 is formed, the vacuum rim 11 is sealed around several layers, and it is kept airtight so that air and air circulation may not be carried out.

도 1 은 본 발명에 따른 런너판의 구조를 설명하기 위한 상면도1 is a top view for explaining the structure of the runner plate according to the present invention;

도 2 는 도 1 의 우측면도FIG. 2 is a right side view of FIG. 1

도 3 은 몰드 베이스 조립체에서 그 내부에 설치되는 런너판의 구조를 보여 주기 위한 상면도3 is a top view for showing the structure of the runner plate installed in the mold base assembly therein;
