Description

회전식 다중 사출 금형Rotary multi injection mold
본 발명은 회전식 다중 사출 금형에 관한 것으로서, 보다 상세하게는 중공 형상을 갖는 사출 제품을 대량으로 생산하기 위해 중앙의 중심축을 기준으로 동일 수평면 상에 일정 각도 마다 회전 합체 시 다른 형상이 되는 복수개의 캐비티를 형성하는 고정측 금형과 가동측 금형을 서로 마주하도록 동시에 설치하고 가동측 금형을 고정측 금형에 대해 소정 각도로 회전시켜 캐비티의 형상을 변경시키면서 사출 수지를 주입하는 방식으로 최종적으로 원하는 사출 제품을 순차적으로 대량 생산하는 회전식 다중 사출 금형에 관한 것이다.The present invention relates to a rotary multi-injection mold, and more particularly to a plurality of cavities which are different shapes when rotationally coalesced at a predetermined angle on the same horizontal plane with respect to the central axis in order to mass produce an injection product having a hollow shape. At the same time, the fixed side mold and the movable side mold are formed so as to face each other and the movable side mold is rotated at a predetermined angle with respect to the fixed side mold to change the shape of the cavity to inject the injection resin while finally injecting the desired injection product. It relates to a rotary multi-injection mold to sequentially mass production.
일반적으로, 합성 수지 재질의 사출 제품을 대량으로 생산하기 위해 사출 금형이 주로 사용되고 있다. 이러한 사출 금형은 한 쌍의 금형이 합체시 내부에 사출 제품의 형상에 대응하는 캐비티가 형성되며 여기에 용융된 수지를 주입함으로써 사출 제품을 생산한다.In general, injection molds are mainly used to mass-produce injection products made of synthetic resin. Such an injection mold has a cavity corresponding to the shape of the injection product formed therein when a pair of molds are merged, and produces an injection product by injecting molten resin therein.
이러한 사출 제품 중 특히 내부에 중공 형상을 갖는 사출 제품을 효율적으로 대량 생산하기 위해 한 쌍의 금형 내 복수개의 캐비티를 형성하여 중간 사출 성형품의 제조한 후 이들을 상호 합체하는 방식으로 사출 제품을 제조하는 다중 사출 금형이 개발되었다.In order to efficiently mass-produce an injection product having a hollow shape among these injection products, a plurality of cavities are formed by forming a plurality of cavities in a pair of molds to manufacture an intermediate injection molded product, and then integrating them. Injection molds have been developed.
이러한 다중 사출 금형의 대표적인 예가 도 28에 도시된 선행기술문헌인 일본공개특허공보 제1987-87315호에 개시된 DSI(die sliding injection) 방식의 다중 사출 금형이 있다.A typical example of such a multi-injection mold is a die injection injection (DSI) type multi-injection mold disclosed in Japanese Laid-Open Patent Publication No. 1987-87315, which is a prior art document shown in FIG.
DSI(die sliding injection) 방식의 다중 사출 금형은 합체시 형성되는 2개의 서로 다른 캐비티에 용융 수지를 각각 주입하여 2개의 중간 사출 성형품을 제조한 후 고정측 금형에 대해 가동측 금형을 슬라이딩 방식으로 직선 이동하여 합체한 후 접합부에 용융 수지를 주입하여 중공 형상을 갖는 사출 제품을 생산한다.DSI (die sliding injection) multi-injection mold manufactures two intermediate injection molded products by injecting molten resin into two different cavities which are formed at the time of coalescence, and then linearly moves the movable mold against the fixed mold. After moving and coalescing, molten resin is injected into the joint to produce an injection product having a hollow shape.
그런데 이러한 DSI 방식의 다중 사출 금형은 슬라이딩 이동에 따른 금형의 직선 이동 공간을 확보해야 하는 문제점이 있을 뿐만 아니라, 슬라이딩 이동에 따라 캐비티를 형성하는 성형부가 외부로 장시간 노출되어 오염이 됨으로써 사출 제품의 불량이 증대되는 문제점이 있다.However, the multi-injection mold of the DSI method has a problem of securing a linear movement space of the mold according to the sliding movement, and the molding part forming the cavity according to the sliding movement is exposed to the outside for a long time, resulting in contamination of the injection product. There is a problem that is increased.
이러한 문제점을 해결하기 위해 도 29에 도시된 선행기술문헌인 일본공개특허공보 제1992-91914호 및 도 30에 도시된 선행기술문헌인 한국공개특허공보 제 2007-41115호에 각각 개시된 DRI(die rotary injection) 방식의 다중 사출 금형이 개발되었다. DRI 방식의 다중 사출 금형은 가동측 금형을 고정측 금형에 대해 슬라이딩 방식이 아닌 회전 방식을 통해 중공 형상을 갖는 사출 제품을 대량으로 생산할 수 있어 DRI 방식의 다중 사출 금형이 갖는 문제점을 해결할 수 있는 장점이 있다.In order to solve this problem, DRI (die rotary) disclosed in Japanese Laid-Open Patent Publication No. 1992-91914, which is shown in Fig. 29, and Korean Laid-Open Patent Publication No. 2007-41115, which is shown in Fig. 30, respectively. An injection type multiple injection mold has been developed. The multi-injection mold of the DRI method can solve the problem of the multi-injection mold of the DRI method by producing a large amount of injection products having a hollow shape by rotating the moving mold with respect to the stationary mold rather than the sliding method. There is this.
그러나 도 29에 도시된 DRI 방식의 다중 사출 금형은 가동측 금형의 경우 지지부(51)에 대해 가동 다이(2)가 직접적으로 맞닿은 상태에서 회전을 하기 때문에 회전 마찰 저항이 발생한다. 이러한 회전 마찰 저항을 줄이기 위해서는 맞닿는 부분에 별도의 오일리스(oilless) 부품을 설치하여야 하며, 오일리스 부품은 소모품이므로 주기적인 교체가 필요하여 설치 및 관리에 많은 시간과 비용이 소요되는 불편함이 있다.However, in the case of the multi-injection mold of the DRI method shown in FIG. 29, since the movable die 2 rotates in a state where the movable die 2 is directly in contact with the support 51, rotational frictional resistance is generated. In order to reduce such rotational frictional resistance, an oilless component must be installed at the contact portion, and since the oilless component is a consumable part, periodic replacement is required, resulting in inconvenience that requires a lot of time and cost for installation and management. .
한편, 도 30에 도시된 DRI 방식의 다중 사출 금형은 가동측 금형(30a, 30b)이 가동측 원판(3)으로부터 승하강판(7)에 의해 고정측 금형(10a, 10b)을 향해 돌출된 상태로 회전이 가능하므로 도 29에 도시된 DRI 방식의 다중 사출 금형이 갖는 문제점을 해결할 수 있다.On the other hand, in the multi-injection mold of the DRI method shown in FIG. 30, the movable side molds 30a and 30b protrude from the movable side disc 3 toward the fixed side molds 10a and 10b by the elevating plate 7. Since the furnace can be rotated, the problem of the multiple injection mold of the DRI method shown in FIG. 29 can be solved.
그러나 도 30에 도시된 DRI 방식의 다중 사출 금형은 회전 시를 제외한 상태에서는 가동측 금형(30a, 30b)이 가동측 원판(3)에 수용되어 있는 상태이기 때문에 캐비티에 주입되는 고온의 용융 수지를 효율적으로 냉각할 수 있는 냉각수 주입 부재를 가동측 금형의 캐비티 부근 내부까지 설치할 수 없는 문제점이 있었다. 뿐만 아니라 가동측 금형(30a, 30b)을 가동측 원판(3)으로부터 돌출 또는 수용시키기 위해서는 회전 장치 이외에 승하강판(7)을 전진 또는 후진 시키기 위해 외부 전원 등에 의해 구동되는 별도의 구동 장치를 구비하여야 하는 문제점이 있었다.However, the multi-injection mold of the DRI method shown in Fig. 30 is a state in which the movable side molds 30a and 30b are accommodated in the movable side disk 3 in the state except for the rotation, and thus the hot molten resin injected into the cavity is used. There has been a problem that a cooling water injection member that can be cooled efficiently cannot be installed inside the cavity vicinity of the movable side mold. In addition, in order to protrude or accommodate the movable side molds 30a and 30b from the movable side disc 3, a separate driving device driven by an external power source or the like for moving the elevating plate 7 forward or backward must be provided in addition to the rotary device. There was a problem.
따라서 본 발명이 해결하고자 하는 기술적 과제는 회전 방식인 종래의 DRI 방식의 다중 사출 금형의 문제점을 해결하여 가동측 금형에 별도의 오일리스(oilless) 부품을 설치할 필요가 없으며, 가동측 금형 내부의 캐비티 부근으로 냉각수를 용이하게 주입할 수 있는 구조를 가질 뿐만 아니라, 별도의 외부 전원 등의 공급이 없이도 회전에 따른 마찰을 없앨 수 있도록 가동측 금형의 일부분이 전진 또는 후진이 가능한 회전식 다중 사출 금형을 제공하는 데 있다.Therefore, the technical problem to be solved by the present invention is to solve the problem of the multi-injection mold of the conventional DRI method of rotation method, there is no need to install a separate oilless (oilless) parts on the movable mold, the cavity inside the movable mold Not only has a structure that can easily inject coolant into the vicinity, but also provides a rotary multi-injection mold in which a part of the movable mold can move forward or backward so as to eliminate friction due to rotation without supplying an external power source. There is.
