그리고, 도 4를 통해 알 수 있듯이, 회전판(320)의 회전에 의해 회전판(320)에 설치된 취출바(400)의 일단부는 회전핀(410)을 중심으로 회전되면서 밀판(111)과 근접한 위치로 이동된다.And, as can be seen through Figure 4, one end of the take-out bar 400 installed on the rotating plate 320 by the rotation of the rotating plate 320 is rotated around the rotating pin 410 to a position close to the mill plate 111 Is moved.

이 과정에서, 상기 취출바(400)의 타단부는 밀판(111)을 밀면서 하부금형(110)의 공간부(110a)로 이동한다.In this process, the other end of the take-out bar 400 moves to the space portion 110a of the lower mold 110 while pushing the wheat plate 111.

이하, 도 5a 내지 도 5c를 참조하여 상기한 구성으로 이루어진 압축성형장치의 작용에 대해 설명하도록 한다.Hereinafter, the operation of the compression molding apparatus having the above-described configuration will be described with reference to FIGS. 5A to 5C.

하부금형(110)의 공간부(110a)에 성형소재가 수용되고, 도 5a에 도시된 바와 같이 상형프레스(200)가 하강하여 상부금형(210)으로 하여금 상기 성형소재를 가압시킨다.The molding material is accommodated in the space 110a of the lower mold 110, and the upper mold press 200 descends to press the upper mold 210 as illustrated in FIG. 5A.

이때, 도 5a에 도시된 바와 같이, 상형프레스(200)에 설치된 열림 방지 지지대(220)는 하부금형(110)의 열림판(113)을 지지하고 있다.At this time, as shown in Figure 5a, the opening preventing support 220 installed in the upper mold press 200 supports the opening plate 113 of the lower mold (110).

다음으로, 일정시간 동안 성형이 이루어지고, 성형이 완료된 후에는 회전부(300)의 회전판(310)이 회전된다.Next, molding is performed for a predetermined time, and after the molding is completed, the rotating plate 310 of the rotating part 300 is rotated.

이때, 도 5b에 도시된 바와 같이, 회전판(310)의 회전력은 변환부재(330)로 전달되고, 이 변환부재(330)는 상기 렉(500)을 상승시킨다.At this time, as shown in Figure 5b, the rotational force of the rotating plate 310 is transmitted to the conversion member 330, the conversion member 330 raises the rack 500.

이 과정에서, 취출바(400)의 일단부는 밀판(111)측으로 이동되어 취출 바(400)의 타단부로 하여금, 밀판(111)을 밀어내도록 한다.In this process, one end of the take-out bar 400 is moved toward the plate 111 to cause the other end of the take-out bar 400 to push out the plate 111.

이에 따라, 밀판(111)과 함께 성형된 제품은 하부금형(110)의 공간부(110a)로부터 외부로 취출된다.Accordingly, the product molded together with the wheat plate 111 is taken out from the space portion 110a of the lower mold 110.

이때, 열림판(113)은 취출되는 성형 제품의 힘에 의해 힌지를 중심으로 회전되어 공간부(110a)를 개방하게 된다.At this time, the opening plate 113 is rotated about the hinge by the force of the molded product is taken out to open the space portion (110a).

이후, 도 5c에 도시된 바와 같이, 회전판(310)이 회전되면, 취출바(400)의 위치는 복원되고, 열림판(113)은 다시 하부금형(110)의 공간부(110a)를 폐쇄시킨다.Then, as shown in Figure 5c, when the rotating plate 310 is rotated, the position of the take-out bar 400 is restored, the opening plate 113 again closes the space portion 110a of the lower mold 110. .

이후, 상기한 일련의 과정이 반복적으로 진행된다.Thereafter, the above series of processes are repeatedly performed.

본 발명의 바람직한 실시예에 따른 압축성형장치에 의하면, 성형이 완료된 제품의 취출 과정이 자동화되어 이루어짐으로써, 작업성이 크게 향상되는 효과가 있다.According to the compression molding apparatus according to the preferred embodiment of the present invention, the take-out process of the finished product is automated, the workability is greatly improved.

또한, 작업자는 고온의 성형 제품을 만지지 않아도 됨으로써, 안전사고를 예방할 수 있다. In addition, the operator does not have to touch the hot molded product, thereby preventing a safety accident.
