또한, 가로형 로터리식 사출성형기는 2개의 다른 사출장치와 회전가능한 인덱스 테이블을 지닌 형체장치로 구성된 사출성형기로서, 2종류의 다른 색을 지닌 제품의 일체성형이나 2종류의 다른 재료의 일체 성형을 수행하는 장치이다. In addition, the horizontal rotary injection molding machine is an injection molding machine consisting of two different injection devices and a molding device having a rotatable index table, which performs integral molding of two different colors or integral molding of two different materials. Device.

이러한 종래의 사출성형기는 제품마다 금형이 제작되어 생산수에 도달하면, 금형교환작업에 의해 생산완료형을 분리한 다음, 생산형을 붙여서 작업을 하는데, 성형조건 설정과 제품 품질을 확인한 다음, 다음 생산을 개시하는 공정을 반복하는 것이다. 따라서, 금형의 탈부착 및 성형조건 설정 등의 순서작업에 많은 시간이 소요되고, 그에따라 제품의 종류가 늘어나면, 작업시간이 늘어나서 생산수가 적은 제품에서는 상당히 생산효율이 저하되는 문제점이 있었다.
When the mold is produced for each product and reaches the number of production, such a conventional injection molding machine separates the completed mold by a mold exchange operation, attaches the production mold, and checks the molding conditions and product quality, and then The process of starting production is repeated.

Figure 2 is an explanatory view of a mold arrangement state of the rotating die of the present invention from the side.

이하, 본 발명의 실시를 위한 구체적인 내용을 첨부된 예시도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings, the specific content for the practice of the present invention will be described in detail.

본 발명은 도 1에 도시된 바와 같이, 서보모터 또는 유압모터와 같은 구동수단(도시되지 않음)에 의해 회전되는 축(10)과, 이 축(10)과 직각방향으로 결합되어 회전되면서 사출장치(20)에 의해 원료가 주입되는 복수의 금형(31)을 가지는 회전형판(30)과, 상기 축(20)에 결합되어 회전되면서 회전형판(30)의 각 금형(31)과 대응되는 금형(41)이 형성된 복수의 형개폐실린더(40)가 설치되는 형개폐 회전형판(50)으로 이루어진 구조이다. The present invention, as shown in Figure 1, the shaft 10 which is rotated by a driving means (not shown), such as a servo motor or a hydraulic motor, and coupled to the shaft 10 in a direction perpendicular to the injection device Rotating die 30 having a plurality of molds 31, the raw material is injected by the (20) and a mold corresponding to each mold 31 of the rotating die 30 while being rotated coupled to the shaft ( 41) is formed of a mold opening and closing rotary mold 50 is installed a plurality of mold opening and closing cylinder 40 is formed.

또한, 상기 형개폐실린더(40)와 더불어, 예를 들어 유압회로에 의해 형개폐실린더(40)에 공급되는 유압공급라인을 각 성형공정에 따라 변경시켜주는 방향전환밸브(도시되지 않음)가 더 설치된다. 유압의 공급은 별도 유압원으로부터 모터에 의해 구동되는 펌프에 의해 방향전환밸브를 거쳐서 형개폐실린더(40)에 공급되어 형개폐실린더(40)가 각 성형공정에 맞게 동작되도록 하는 것이다.
Further, in addition to the mold opening and closing cylinder 40, for example, a direction switching valve (not shown) for changing the hydraulic supply line supplied to the mold opening and closing cylinder 40 by the hydraulic circuit according to each molding process is further included. Is installed. The hydraulic pressure is supplied to the mold opening / closing cylinder 40 through a direction switching valve by a pump driven by a motor from a separate hydraulic source so that the mold opening and closing cylinder 40 is operated for each molding process.

본 실시예에서 상기 회전형판(30)에 구비되는 금형(31)은 각기 다른 형상을 가지는 금형으로서 6개를 설치하여 60도 간격을 두고 회전되도록 되어 있다.In the present embodiment, the mold 31 provided in the rotatable plate 30 is installed as six molds having different shapes so as to rotate at intervals of 60 degrees.

또한, 회전형판(30)에 구비되는 금형(31)은 순차적으로 형체, 사출, 제 1냉각, 제 2냉각, 형개, 압출공정을 거치도록 되어 있다. In addition, the mold 31 provided in the rotatable plate 30 is subjected to a mold, injection, first cooling, second cooling, mold opening, and extrusion processes sequentially.

또한, 상기 형개폐 회전형판(50)은 회전형판(30)과 간격을 두고 마주보도록 설치되고, 이 형개폐 회전형판(50)에 형성된 금형(41)은 회전형판(30)에 형성된 금형(31)에 대응되도록 6개가 60도 간격을 두고 설치된다. In addition, the mold opening and closing rotatable plate 50 is installed so as to face at intervals with the rotating mold 30, the mold 41 formed on the mold opening and closing rotatable plate 50 is a mold 31 formed on the rotating mold 30 6 units are installed at 60 degree intervals.

또한, 상기 축(10)의 양쪽 단부는 지지대(11)(12)에 의해 지지되고, 축(10)의 회전시 원활하게 회전되도록 베어링(13)(14)이 설치되어 있다. In addition, both ends of the shaft 10 are supported by the supports 11 and 12, and the bearings 13 and 14 are installed so as to rotate smoothly when the shaft 10 rotates.

또한, 한쪽 지지대(11)의 상부측에는 사출장치(20)가 설치되어서 회전형판(30)의 각 금형(31)에 원료인 사출물을 주입하도록 되어 있고, 본 발명에서는 1개의 사출장치(20)만으로 사출작업이 이루어진다. In addition, an injection apparatus 20 is installed on the upper side of one support 11 to inject an injection material, which is a raw material, into each mold 31 of the rotating mold 30. In the present invention, only one injection apparatus 20 is used. Injection work takes place.

또한, 도면에는 도시되지 않았지만, 본 발명의 사출성형기는, 성형공정중 사출공정후 회전형판의 각 금형이 각각의 위치에 따라 수행하는 냉각, 형개, 압출공정을 제어하는 제어부가 탑재되어 있다.
In addition, although not shown in the drawings, the injection molding machine of the present invention is equipped with a control unit for controlling the cooling, mold opening, and extrusion process performed by each mold of the rotating mold after the injection process during the molding process according to each position.

이러한 구성을 가지는 본 발명은 구동수단에 의해 축(10)이 회전하면, 이 축(10)과 직각방향으로 결합된 회전형판(30)과 형개폐 회전형판(50)이 동시에 회전하게 되는데, 연속적으로 회전하는 것이 아니라, 순차적으로 각 공정에 맞게 회전하는 것이다.In the present invention having such a configuration, when the shaft 10 is rotated by the driving means, the rotary mold 30 and the mold-opening rotary mold 50 coupled to the shaft 10 at right angles are rotated at the same time. It is not to rotate, but to sequentially rotate for each process.

다시 말해서, 형개폐실린더(40)를 통해 금형(41)과 회전형판(30)의 금형(31)과 결합하는 형폐 및 형체과정과, 사출장치(20)에서 성형하고자 하는 원료인 사출물을 계량 및 사출하여 회전형판(30)의 해당 금형(31)에 주입하는 과정과, 냉각과정, 형개과정, 압출과정의 순서로 작업공정이 이루어지고, 이 작업공정에 맞게 축(10)이 60도 간격을 두고 회전하여 회전형판(30)과 형개폐 회전형판(50)의 각 단계별 공정이 이루어진다. In other words, through the mold opening and closing cylinder 40, the mold closing and clamping process coupled with the mold 41 and the mold 31 of the rotating mold 30, and the injection material, which is a raw material to be molded in the injection apparatus 20, is measured and measured. The process of injection and injection into the corresponding mold 31 of the rotating mold 30, the cooling process, the mold opening process, and the extrusion process are performed in order, and the shaft 10 is spaced 60 degrees according to the work process. By rotating and leaving each step of the rotating mold 30 and the mold opening and closing rotating mold 50 is made.

따라서, 1대의 사출성형장치로 복수의 제품을 동시에 성형할 수 있으므로, 다품종 소량생산에서의 금형교환작업, 작업조건 설정과 같은 번거로운 작업에 의해 낭비되는 시간을 없애고, 효율적으로 생산이 가능한 것이다.
또한, 본 발명은 상기 회전형판(30)이 축(10)에 직각방향으로 결합되도록 수직하게 세워진 구조를 가지므로, 수평상태로 배치하는 것에 비해 공간적인 제약을 덜 받으며, 축(10)의 구동에 의해 회전형판(30)과 형개폐 회전형판(50)을 동시에 회전시키므로, 그 만큼 단순한 구조를 이루면서 여러 성형품을 제조할 수 있고, 장치의 내구성 및 수명도 향상되는 것이다.
Therefore, since a single injection molding apparatus can mold a plurality of products at the same time, it is possible to eliminate the time wasted by cumbersome work such as mold replacement work and work condition setting in small quantity production of multi-products, and to produce efficiently.
In addition, the present invention has a structure erected vertically to be coupled to the rotational plate 30 in a perpendicular direction to the shaft 10, less space constraints than the horizontal arrangement, the drive of the shaft 10 By rotating the rotatable plate 30 and the mold opening and closing rotatable plate 50 at the same time, it is possible to manufacture a variety of molded articles while making a simple structure, the durability and life of the device is also improved.
